How do I use trans in a placeholder as an optional attr?
It's possible to render choice fields this way:
{% for radio in form.my_radio_field %}
{{ radio.tag }}
{{ radio.choice_label }}
{% endfor %}
This gives more control over the generated HTML. It's not currently possible to use widget tweaks template tags in this case. Eg.:
{% for radio in form.my_radio_field %}
{{ radio.tag|add_class:"some-class" }}
{{ radio.choice_label }}
{% endfor %}
Some attributes trigger behaviors and meanings simply by their presence, such as the readonly attribute. In these cases even an empty string passed to render_field will cause the field to have the readonly attribute and be read-only, so there is no way to do this and pass 'false' in any form.
In the way that render_field supports both = and += to set or append an attribute, a syntax to optionally add would be great. OR, explicit support for fields like readonly that would just ignore the attribute if the value given was false.
I'm getting a rather cryptic error "expected str instance, BoundField found"
Not sure what the issue is. add_class
works though...
Would it be possible to change or replace an html tag for a field? An example use case scenario is when I have to use a form element as a radio button. django renders it as a list of choices, but bootstrap does not, and hence the rendered form is ugly to look at.
This issue tracks the implementation of the Jazzband guidelines for the project django-widget-tweaks
It was initiated by @kmike who was automatically assigned in addition to the Jazzband roadies.
See the TODO list below for the generally required tasks, but feel free to update it in case the project requires it.

@kmike, can you help to find the way to realize feature of setting up attributes for options-tags inside rendering select-widget ('disabled', for example)?
Maybe, this work is not for widget-tweaks, but for separate widget?
I am using render_field inside loop how to pass loop counter value to render field methods
I tried with following code but loop counter taking as string
{% for u in formset.forms %}
{% render_field u.name class+="form-control" id="name-{{forloop.counter0}}" %}
{% endfor %}
Trying to use v 1.4.1 with Python 2.7 and 3.4 I can't get it working in Django 1.8
Always receiving:
'widget_tweaks' is not a valid tag library: Template library widget_tweaks not found
on
{% load widget_tweaks %}
Any help?
And yes, it is enabled in my INSTALLES_APPS section in the settings.py
I have this form rendering template in django, and render_field
is not working inside if-else
:
{% load widget_tweaks %}
{% for field in form %}
<div class="form-group">
{{ field.label_tag }}
{% if form.is_bound %}
{% if field.errors %}
{% render_field field class="form-control is-invalid" %}
{% for error in field.errors %}
<div class="invalid-feedback">
{{error}}
</div>
{% endfor %}
{% else %}
{% render_field field class="form-control is-valid" %}
{% endif %}
{% else %}
{% render_field field class="form-control" %}
{% endif %}
{% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text }}
</small>
{% endif %}
</div>
{% endfor %}
And it renders this:
But when I try a smaller version of the above code like following, then also it still doesn't work:
{% load widget_tweaks %}
{% for field in form %}
<div class="form-group">
{% if field.errors %}
{% render_field field class="form-control is-invalid" %}
{% else %}
{% render_field field class="form-control is-valid" %}
{% endif %}
{% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text }}
</small>
{% endif %}
</div>
{% endfor %}
And renders this:
But when I remove all if-else
's:
{% load widget_tweaks %}
{% for field in form %}
<div class="form-group">
{{ field.label_tag }}
{% render_field field class="form-control" %}
{% if field.help_text %}
<small class="form-text text-muted">
{{ field.help_text }}
</small>
{% endif %}
</div>
{% endfor %}
Then it renders correctly:
But I need the if-else's to check for form errors and add error messages to form accordingly, will appreciate any help. So why is render_field
not working with if-else
? How to resolve this ? Any other ways to use widget_tweaks to render error ?
Hi!
Judging from tox.ini
line 13 and the traceback I get with Django 2.1(.2 but not with 2.0.9), `django-widget-tweaks does not seem ready for Django 2.1. Are there plans to add support for it?
Thanks in advance!
Best, Sebastian
PS: The traceback is this:

When I Use wagtail 2 and pipenv i get ModuleNotFoundError: No module named 'widget_tweaks'
So i was getting a weird bug, the template would say:
And in the terminal (running the development server):
Any way, problem appear when using the render_field tag:
Digging in i found the problem on widget_tweaks/templatetags/widget_tweaks.py
(line 26, 31):
# if not PY26:
# # See https://bugs.python.org/issue1515.

# field = copy.deepcopy(field)
(doble comment :P)
So the comment says Django (1.7+), but i think there should be a second condition because it looks like in some newer version of Django, that statement stopped working.
My configuration:
Thanks for reading! 👍

Hey,
I discovered a change between Django 1.10.6 and 1.11, which causes set_attr
to silently ignore a Select widget with empty choices.
The incriminated line: https://github.com/kmike/django-widget-tweaks/blob/master/widget_tweaks/templatetags/widget_tweaks.py#L10
The underlying problem is that a Select widget with empty choices will evaluate to False
as its len
will be 0 in Django 1.11, while being 1
in <1.11.
I reported the change to the Django devs too, as this change is undocumented, and I'm not sure if it is intended that way. Link to the ticket: https://code.djangoproject.com/ticket/28058
If the change is intended, you'll have to update that check.
Cheers,
I would like to do something like this:
{{ form.name|attr:"placeholder:"some_variable }}
So that value of some_variable appears as placeholder of name field.
This obviously throws a Template Syntax Error .
Is there any other way to do this ?
I noticed a very strange behaviour when using an {% include %}
statement along with the Django debug toolbar enabled. Django-widget-tweaks filters are ignored when using the following (_field.html
just contains {{ field }}
):
{% include "_field.html" with field=form.foo|attr:"title:hello" %}
While it works fine when using {{ field }}
in the main template instead of the include
statement or when disabling the debug toolbar. Maybe the widget is rendered by the Django debug toolbar before being rendered in the page, and the original as_widget
method is put back before it's rendered again in the template.
I created a project here that demonstrates the bug: https://github.com/sephii/django-widget-tweaks-bug
Just pip install
the requirements, run the server, and go to https://localhost:8000/, you'll see the field that's included doesn't have the "title" attribute.
how about adding events dynamically i.e :
{% render_field field onchange='"function('+object.id +')"' %}
while object.id comes from server side.
is this possible?
I'm using django v1.11.7 with Jinja2 v2.10 as the template engine. I want to use django-widget-tweaks to integrate bootstrap, so I can style form elements in my website.
This package won't work with Jinja templates, since it needs to load a custom tag set into the Jinja environment. Loading tag sets can be complex, since I may need to write an extension. I don't want to switch from Jinja2 since it offers more flexibility compared to django templates.
Is there some way to get django-widget-tweaks to work with Jinja?
So I've been troubleshooting this for many hours now, without avail.
I've pip-installed django-widget-tweaks
, and included 'widget_tweaks' in my settings.py
file.
I also have this in my base.html
file:
{% load static %}
{% load i18n %}
{% load compress %}
{% load widget_tweaks %}
I've tried a gazillion ways to {{ field|add_class:"form-control" }}
or {% render_field...%}
, and each time it will throw an error along the lines of "did you forget to register this tag?
My .pug
file which extends base.html
:
div(class="col-lg-4 col-md-6 cold-sm-12")
- var da_form = form
H3 Bottle Form
//- TODO: fix fields to dynamically adjust
form(method="post" action=".")
| {% csrf_token %}
for field in da_form.visible_fields
div(class="form-group row")
label(class="col-lg-4 col-md-3 col-sm-6 col-form-label") {{field.label_tag}}
div(class="col-lg-8 col-md-3 col-sm-6")
| {{ field|add_class:"form-control" }}
input(class="form-control")(type="submit" value="submit")
Error when using add_class:
Invalid filter: 'add_class'
Error when using render_field
:
Invalid block tag on line 54: 'render_field', expected 'empty' or 'endfor'. Did you forget to register or load this tag?
Notice that while this is a .pug
file, the |
basically means this is treated the very same like HTML/django variable.
Things I've tried and didn't help:
widget_tweaks
and re-installingfor field in da_form
instead of for field in da_form.visible_fields
.pug
file and base.html
, either, and both.core.widget_tweaks
(where core
is the app where my settings.py file is, that threw an error that core.widget_tweaks
isn't a registered tag)All test environments except py26-dj12 using python 2.7 specified in testenv.
Widget tweaks cuts off initial classes provided to subwidgets.
Used both directly(not through custom widget, and with custom widget). Result is same.
Consider following usage:
Template:
{% render_field field class+='validate' %}
Form:
class MySparEditForm(forms.ModelForm):
posting_start = forms.SplitDateTimeField(widget=SplitDateTimeWidget(time_attrs={'class': 'datepicker'}, date_attrs={'class': 'timepicker'}))
class Meta:
model = Spar
widgets = {
'posting_end': DateTimePicker(),
'main_text': TextArea(),
'image': forms.FileInput(),
'active': CheckBox()
}
fields = [
'active',
'name',
'type',
'description',
'main_text',
'image',
'participants',
'posting_start',
'posting_end',
]
And DateTimePicker
widget code:
def add_classes(attrs, classes):
if 'class' in attrs:
attrs['class'] += f' {classes}'
else:
attrs['class'] = classes
class DateTimePicker(SplitDateTimeWidget):
datepicker_classes = 'datepicker'
timepicker_classes = 'timepicker'
def __init__(self, attrs=None, date_format=None, time_format=None, date_attrs=None, time_attrs=None):
date_attrs, time_attrs = date_attrs or {}, time_attrs or {}
add_classes(date_attrs, self.datepicker_classes)
add_classes(time_attrs, self.timepicker_classes)
super().__init__(attrs, date_format, time_format, date_attrs, time_attrs)
Then result is:
http://joxi.ru/MAjBv7I40kDdAe.png
It replaces initial classes on subwidgets with provided via +=
instead of concatenating them.
Hi I would like to know if it is possible to put a forloop counter inside the template tag something like:
{% for emergencycontact_form in emergency %}
{{ emergencycontact_form.emergency_province|add_class:"form-control first-choice class_province"|attr:"data-toggle:tooltip"|attr:"data-address:form-forloop.counter-emergency"}}
{% endfor %}
P.S. the issue of the forloopcounter is in the last attribute
The latest version here on GitHub (v1.4.2) isn't available through PyPI, I assume someone with the correct permissions needs to publish it?
I have {{ field|add_class:"mdl-textfield__input"|attr:"type:date"}}
and I expected <input type="date" name="start_date" value="2016-07-08" class="mdl-textfield__input" required id="id_start_date">
but in fact it produced <input type="text" name="start_date" value="2016-07-08" type="date" class="mdl-textfield__input" required id="id_start_date">
(notice the two types, with Google Chrome ignoring the second type)
I'm relying on this for a couple of small django apps because I didn't find any viable alternatives.
It appears as if the GitHub repository was moved sometime in the last year and since then nothing really happened.
I'd be willing to consider maintaining it, if @jazzband doesn't want to.
add_class is working fine with DateField but it is overriding the class when using it on a DateTimeField and after that, the calendar widgets do not appear. My guess is because DateTimeField is formed by two different inputs and when it executes the append_attr
function it doesn't detect their class so its lost during the next function calls.
Hi, thanks for the great repo! I am trying to add a textarea field and set the value with the render_field tag. I am unable to do this, and not sure if it is supported. Is so, please explain. Thanks!
from my django template
{% render_field my_form.my_text_field rows='10' value='foobar' %}
from my forms.py
class MyForm(forms.Form):
my_text_field = forms.CharField(widget=forms.Textarea())
What I want rendered
<textarea rows="10" name="my_field" id="id_my_field">foobar</textarea>
Hi,
How can I get to set a initial value like:
{% render_field form.data_entrega attr='required' value={{data_entrega}} required='required' class='form-control form-control-inline input-medium date-picker' %}
Thanks
I noticed this possible bug while writing tests for the render_field
tag.
Intuitively I think {{ form.simple|attr:"foo:bar"|attr:"foo:baz" }}
should return this:
<input foo="baz" type="text" name="simple" id="id_simple" />
Instead it returns
<input foo="bar" type="text" name="simple" id="id_simple" />
Test case to demonstrate this issue: treyhunner/widget-tweaks@a61c08d28150560da140d2480f239798e7ffa3df
I don't know if I'm doing something stupid, but when I use
{{ user_form.password1|add_class:"form-control pull-right" }}
,
a new "form-control pull-right" is added to the HTML output every time I refresh the page, so eventually I get something like
<input class="form-control pull-right form-control pull-right form-control pull-right form-control pull-right form-control pull-right ... />
Any ideas?
Please!
Is there any way to render a field with a different widget type?
I need to render a select input into a text input.
In the django Form class, for specific reason, I can't set widget=forms.TextInput, but I should be able to do it in a smart way like that:
{% render_field form.start_date class+="form-control" type="text" %}
But what I got is a HTML tag instead.
1 QUESTION: How to use django-tweaks with MultipleChoiceField field?
2QUESTION: I have form with MultipleChoiceField field which has dynamic list for choices
. Sometimes dynamic list can be empty []. So I want to show message in template when its empty but next code didnt show message.
forms.py:
class RequirementForm(forms.ModelForm):
symbol = forms.MultipleChoiceField(widget=forms.CheckboxSelectMultiple)
class Meta:
model = Requirement
fields = ('symbol',)
requirement_add.html:
{% load widget_tweaks %}
<form method="post" action="{% url 'project:requirement_add' project_code=project.code %}">
{% for field in form %}
{% render_field field class="form-control" %}
{% empty %}
<p>Form is empty!</p>
{% endfor %}
</form>
I am using the following the code to create a form.
Without col-md-6, the button will be aligned on vertically. But with it, the button floats to the right.
Any idea to fix this?
{% load widget_tweaks %}
<form class="form" classaction="" method="post">{% csrf_token %}
<div class="form-group col-md-6">
<label for="title">Title</label>
{%render_field form.title class="form-control" %}
</div>
<button type="submit" class="btn btn-success">Save</button>
</form>
Version 1.3 works fine, this only happens in 1.4.

I tried to add angular.js ng-class attr.
for example:
{% render_field form.name ng-class="{'form-control form-white actuator_name':true, 'form-error': errors.name}" %}
And it fails. this one approach works fine:
{{ form.name|attr:"ng-class:{'form-control form-white actuator_name':true, 'form-error': errors.name}" }}
It seems that the render_field fails because of this
https://github.com/kmike/django-widget-tweaks/blob/master/widget_tweaks/templatetags/widget_tweaks.py#L113
It matches the end of value in the wrong place (right after { in my case)
Hi! I try add the field_type filter as a class to a field as a follow:
{% with "{{field|field_type}}" as field_type %} {% render_field field class+="form-control {{field_type}}" required="true" %} {% endwith %}
But this way doesn't work.
Please, anyone could tell me how add this filter as a field's class?
Thanks!
PD: I'm sorry for my English!
{% url 'myurl-upload-os' as upload_file %}
{{form_upload.image |attr:"multiple" |attr:'data-url:"{% url upload_file %}' }}
thanks guys!!
<!-- attributes without parameters --> {{ form.search_query|attr:"required" }}
inserts required=""
instead required
#58 This still is not fixed. Django 1.11
I have this problem:
For my responsive html page i have to replicate my content 2 times with different css class and placeholder for my input field:
Here is the code:
{% trans "Search with keywords" as search_q_mobile_token %}
{% render_field form.q placeholder=search_q_mobile_token class="mobile-friendly" %}
{% trans "Search with keywords, name or email" as search_q_desktop_token %}
{% render_field form.q placeholder=search_q_mobile_token class="desktop-friendly" %}
Expected result:
<input class="mobile-friendly" id="id_q" name="q" placeholder="Search with keywords" type="search">
<input class="desktop-friendly" id="id_q" name="q" placeholder="Search with keywords, name or email" type="search">
What i see:
<input class="mobile-friendly" id="id_q" name="q" placeholder="Search with keywords" type="search">
<input class="desktop-friendly" id="id_q" name="q" placeholder="Search with keywords" type="search">
As you can see the first output is as I expected, instead the second have a correct css class but the same placeholder of the first.
I thought it was a {%trans%} templatetag problem but if I print it on my html page using {{search_q_desktop_token}} just before the second {% render_field ..%} I see the correct item..
Someone could helps me to resolve this strange problem?
Hello,
This:
{% render_field field placeholder=field.label.capitalize %}
Is actually rendering that:
<input ...placeholder="field.label.capitalize"...>
Cheers,

Hi!
I'm migrating my project from Django 1.9 to 1.11. I have the following code which was working great in Django 1.9 but doesn't work in Django 1.11:
{% render_field form.q type='search' required='required' class='term-input' %}
And here's my Django form:
class SearchForm(forms.Form):
q = forms.CharField(label='Search')
Only if I explicitly override the field widget's type
atribute - it works:
class SearchForm(forms.Form):
q = forms.CharField(label='Search', widget=TextInput(attrs={'type': 'search'}))
AFAIU, Django 1.11 has moved widgets rendering from Python code into templates (which is 100% positive change IMO), but now they treat type
attribute in a special way:
{# django-1.11.7/django/forms/templates/django/forms/widgets/input.html #}
<input type="{{ widget.type }}" name="{{ widget.name }}"{% if widget.value != None %} value="{{ widget.value|stringformat:'s' }}"{% endif %}{% include "django/forms/widgets/attrs.html" %} />
So when I override
{% render_field form.q required='required' class='term-input' data-x=1 %}
... - everything works great, but not when I change type
:(
It would be nice to have add_class be able to accept field labels.
See https://bitbucket.org/kmike/django-widget-tweaks/issues/6/not-able-to-add-class-on-label
I've originally posted this on the SO, however it seems that bug lays on the django-widget-tweaks
side.
I've tried a very basic load test on my django
app, something among the lines:
for _ in {1..50}; do for x in {1..50}; do curl http://example.com &> /dev/null; done & done
After a while server started returning http 500
, the reason for that was RecursionError

Now it seems that the culprit might be django-widget-tweaks
, but is it? The way I use widget-tweaks
is more or less copy/paste from their docs.
<div class="form-group{% if usr_form.email.errors %} has-error{% endif %}">
{{ usr_form.email.errors }}
{% render_field usr_form.email class+="form-control" placeholder="Email Address" %}
</div>
Below is the snipped from requirements.txt
:
Django==1.11.4
django-widget-tweaks==1.4.1
EDIT
I've refactored my forms to the:
class UserModelForm(ModelForm):
class Meta:
model = models.User
fields = ['name', 'email']
widgets = {
'name': TextInput(attrs={'class': 'form-control', 'placeholder': 'Full Name'}),
'email': EmailInput(attrs={'class': 'form-control', 'placeholder': 'Email Address'}),
}
And HTML:
<div class="form-group{% if usr_form.name.errors %} has-error{% endif %}">
{{ usr_form.name.errors }}
{{ usr_form.name }}
</div>
<div class="form-group{% if usr_form.email.errors %} has-error{% endif %}">
{{ usr_form.email.errors }}
{{ usr_form.email }}
</div>
Haven't seen http 500
since, so it's definitely django-widget-tweaks
bug.
Thanks for wonderful widget-tweaks! Unfortunately I'm currently facing serious problem with multiple-times rendering same field. Every subsequent field rendering repeats "type" attribute from previous rendering. Interestingly it works for all other usual HTML attributes I tried (class, id, ...).
This buggy behavior is the same for render_field
tag and filters like attr
, add_class
. Better to say it with example:
# render_field tag remembers first "type" forever:
{% render_field form.price_per_person type="disabled" class="form-control" %}
<input id="..." name="..." type="disabled" class="form-control" />
# even if not specified (it should be number because field is Django DecimalField):
{% render_field form.price_per_person %}
<input id="..." name="..." step="0.01" type="disabled" />
# the same "always remembered" applies for attr filter:
{{ form.price_per_person|attr:"type:disabled"|add_class:"form-control" }}
<input id="..." name="..." type="disabled" class="form-control" />
{{ form.price_per_person }}
<input id="..." name="..." type="disabled" />
Under some circumstances it will even stops you from manually overwriting "type" attribute to rescue:
# first occurrence is okay:
{% render_field form.price_per_person type="disabled" class="form-control" %}
<input class="form-control" id="..." name="..." type="disabled" />
# but subsequent usage keeps first-time used type value ONLY IF you specify any
# new attribute except "type" like "id". You specify hidden type, but it stays disabled.
{% render_field form.price_per_person id="..." type="hidden" %}
<input id="...." name="..." type="disabled" />
Using Django==1.9.7, django-widget-tweaks==1.4.1.
This is a feature request that may become a pull request if I decide to submit code for these features.
I have a modification of render_field
that I have been using (as render_multi_field
currently) that allows widgets from multi-widget fields to be rendered individually. This allows finer control over the rendering of fields using multi-widgets such as SplitDateTimeWidget
.
Another widget type that often requires more control than Django offers by default is the RadioSelect
widget which uses RadioInput
subwidgets. This widget could be rendered with more control if subwidgets were rendered individually. RadioInput's tag
method could be used to render each radio button when looping over them via the subwidgets
method.
