:seedling: Seed your Django database with fake data

django-seed's Issues

fake-factory dependency error

Command:
seeder = Seed.seeder()
Error:

ImportError: The ``fake-factory`` package is now called ``Faker``.
Please update your requirements.

Unique value

I want to use same email for my generated code.

seeder.add_entity(User, 10, {
    'username': lambda x: seeder.faker.name(),
    'email': lambda x: seeder.faker.email(),
    'password': lambda x: seeder.faker.password(),
})

In this code, I want to use same email that is in email field for username. Is there any way I can do tha?

Issues with max_length

DataError: value too long for type character varying(50)

Seeding should take into account the max_length of the field.

using naive date times when timezone is active

If the django settings uses time zones, DateTimeFields throw the following Runtimewarning:

RuntimeWarning: 
DateTimeField StoryPost.published received a 
naive datetime (1978-07-06 22:37:20) 
while time zone support is active.
  RuntimeWarning)

Possible solution:
when populating date time fields, check if timezone is active via settings.py, and if it is,
set the field value via timezone.now()

error: unrecognized arguments: --seeder

"--seeder" arg not working in management command

this command:
./manage.py seed location --number=10 --seeder "Address.hours" "None"

gives me:
manage.py seed: error: unrecognized arguments: --seeder Address.hours {}

Django==3.2.4
Python 3.8.10

DateTimeField with auto_add_now always has now value

I have a DateTimeField with auto_add_now=True.
When I run

seeder.add_entity(Item, 15, {'date': lambda x: seeder.faker.date_time_between(start_date='-1y'),})
seeder.execute()

(or without defining the date generator) I only get Items with the date equal to the time I run the code.

I believe this is incorrect behaviour, please correct me if I'm wrong.

Not respecting uniqueness

https://github.com/Brobin/django-seed/blob/master/django_seed/seeder.py#L30-L36

This pulls a random value from inserted values; it needs to be one to one.

Add_entity and execute actions returns numbers elements multiplied by 2.

Hi.
I discover problem with package. Execute operation doubles numbers of elements. More on the screen from debug actions.

Best regards.

pip install doesn't give management command

Using Django 1.7.7 and Python 2.7.5 I did a pip install and the management command doesn't get installed. I even tried pip installing using git+git://github.com/Brobin/django-seed.git and that didn't work either.

Calling `.seed()` on instances is deprecated.

Hi,

Using django_seed with Faker 3.0.0 causes the following exception:

TypeError: Calling `.seed()` on instances is deprecated. Use the class method `Faker.seed()` instead.

It can be traced up to line 35, faker method:

  File "/Users/User/Projects/Django/MyProject/TestApp/management/commands/generate.py", line 13, in generate
    seeder = Seed.seeder()
  File "/Users/User/Projects/Django/MyProject/lib/python3.7/site-packages/django_seed/__init__.py", line 42, in seeder
    faker = cls.fakers.get(code, None) or cls.faker(codename=code)
  File "/Users/User/Projects/Django/MyProject/lib/python3.7/site-packages/django_seed/__init__.py", line 35, in faker
    cls.fakers[code].seed(random.randint(1, 10000))
  File "/Users/User/Projects/Django/MyProject/lib/python3.7/site-packages/faker/proxy.py", line 79, in __getattribute__

I believe the issue may lie in the fact that since Faker v2.0.4, calling seed on Faker instances has been disabled.

Check https://faker.readthedocs.io/en/master/fakerclass.html#breaking-change for the rationale and fix.

The moment I got this exception I was using:

Faker 3.0.0
django-seed 0.1.9 
python 3.7

Thanks,

Eddie

Not taking into account CharField with a max_length < 5

I have the following model in one of my apps:

class Currency(models.Model):
    abbrev = models.CharField(max_length=3, unique=True)

As the CharField is currently implemented, I am having problems getting a word that has a maximum length of 3

Problems with postgres fields

Django now supports postgres fields like ArrayField, JSONField, HStoreField etc.

https://docs.djangoproject.com/en/1.9/ref/contrib/postgres/fields/

seed management command as well as seeder.add_entity fails since they are not been detected with FieldTypeGuesser.

It would be great to have this support at least at the add_entity level.

django_seed.exceptions.SeederException: Field demo_models.Waiter.name cannot be null

attempting to run my code as:

from django_seed import Seed

seeder = Seed.seeder()

from report_builder_demo.demo_models.models import Waiter, Restaurant,Foo,Place,FooExclude,Bar
seeder.add_entity(Waiter, 15)
seeder.add_entity(Restaurant, 10)
seeder.add_entity(Place, 5)
seeder.add_entity(Bar, 10)
seeder.add_entity(FooExclude, 5)
seeder.add_entity(Foo, 10)
inserted_pks = seeder.execute()

django_seed.exceptions.SeederException: Field demo_models.Waiter.name cannot be null

the model is as follows:

class Waiter(models.Model):
    restaurant = models.ForeignKey(Restaurant)
    name = models.CharField(max_length=50)

    def __str__(self):
        return "%s the waiter at %s" % (self.name, self.restaurant)

Figure out if seeded data should interact with existing data

In cases where a model wants a relationship with another model through one-to-one, many-to-one, or many-to-many, currently, it can only use objects that were created in the current execute. It can look in the database and find other objects that match, but those might not have been created by django-seed. It would be helpful to have a flag that allowed django-seed to make relationships with existing data when seeding. Otherwise it should only use objects that are stored in the inserted list from the current django-seed session.

This will also require looking into how the "inserted" list is stored over multiple executes.

AttributeError(field): Need attention regarding possible PR

Hi Brobin.

I opened the ticket regarding this line

In my project I use a field 'Point' from GeoDjango and I faced AttributeError.

I can make a PR for this field, but I am sure, that time will come and someone will face AttributeError again.

I see few possible ways how AttributeError can be solved (at least how to add some flexibility) and would like to discuss it with you in order to avoid work which will not be merged.

Solution # 1:
Ignore fields if field has "null=True"

Solution # 2:
If dict has 'some_new_field' (field which is not covered by django-seed), AttributeError should not be raised, because dict already has info what type of faker must be used.

seeder.add_entity(Player, 10, {
    'score':    lambda x: random.randint(0,1000),
    'some_new_field': lambda x: seeder.faker.some_item(),
})

Solution # 3:
Just to add an optional flag, something like 'ignore_unknown_fields=True'

seeder.add_entity(Player, 10, {
    'score':    lambda x: random.randint(0,1000),
    'some_new_field': lambda x: seeder.faker.some_item(),
},
ignore_unknown_fields=True
)

and let django-seed to work just with known fields.

Solution # 4:
Implement all solutions :)

What is acceptable? Maybe you have your own thoughts?
Thanks.

AttributeError: 'str' object has no attribute 'isoformat'

File "/home/vagrant/.local/lib/python2.7/site-packages/django_seed/seeder.py", line 149, in execute entity = self.entities[klass].execute(using, inserted_entities) File "/home/vagrant/.local/lib/python2.7/site-packages/django_seed/seeder.py", line 92, in execute for field, field_format in self.field_formatters.items() AttributeError: 'str' object has no attribute 'isoformat'

This happens when running seeder.execute() upon ajax call.

How do I run the seeder from model instances?

I made a file called seed.py in the root of my Django project (next to manage.py) so I can use Seed.seeder() .
When I run the command like this:

$ python seed.py

I get the following error:

django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

AttributeError: 'Generator' object has no attribute 'seed_instance'

I cannot seem to get it to create data for any application I have so far.

python manage.py seed booking --number=15

Error message:

 cls.fakers[code].seed_instance(random.randint(1, 10000))
AttributeError: 'Generator' object has no attribute 'seed_instance'

Using python3.8

Add missing field types to FieldTypeGuesser

Add these new fields. There should be faker methods for most of these.

• BinaryField: binary data?
• CommaSeparatedIntegerField: extends CharField ex -> "1,2,3"
• DurationField: needs a timedelta object
• FileField: not sure...
• FilePathField: Extends CharField
• GenericIPAddressField: same as IPAddressField which is deprecating?
• PositiveIntegerField: random.randint
• PositiveSmallIntegerField: random.randint
• UUIDField: like CharField? See ff3f9c7

Default value in help

Param number has default value but it's not obvious from help text.

Array Field is still not properly supported in latest version(0.3.1)

Connected issue.
#104

We are using the latest version, but Array Field is still not properly supported.

pip list

django-seed 0.3.1

No matter what form the model is modified, Array Field is not properly recognized.

models.py

1. blablaField = ArrayField(models.TextField(), blank=False, size=6, null=True)
 
2. blablaField = ArrayField(
        models.TextField(),
        blank=True,
        size=6,
        null=True,
    )

3. blablaField = ArrayField(
        models.TextField(
            max_length=100,
            null=True,
        ),
        blank=True,
        size=6,
        null=True,
    )

4. blablaField = ArrayField(
        models.TextField(
            max_length=100,
            null=True,
            blank=True,
        ),
        blank=True,
        size=6,
        null=True,
    )

When I deleted the field only right, it worked.

models.py

~~~

(delete blablaField)

~~~

I think an error occurs when the model is verified in the add_entity process. This is because an error occurred even if a field value was not added within add_entity.

seed_blablas.py

class Command:

def handle(self, *args, **options):
        total = options.get("total")

psycopg2 is required for ArrayField even if project isn't using postgres

Even though I'm not using Postgres for Django (just yet), the use of ArrayFields requires me to have it installed.

I'm getting this error while trying to seed this model:

class Contact(models.Model):
    telephone = models.CharField(max_length=50, null=True, blank=True)
    mobile_phone = models.CharField(max_length=50, null=True, blank=True)
    address = models.CharField(max_length=50, blank=True, null=True)
    postal_code = models.CharField(max_length=50, null=True, blank=True)
    email_address = models.EmailField(max_length=100, blank=False, null=False)
    website = models.URLField(null=True, blank=True)

I suspect this is due to the address field, since faker.address() may return an address longer than 50 chars.

Can't install from requirements file via chef / bash script - but I can manually

When I try to install django-seed by running pip install -r requirements.txt I get the following stack trace complaining about django-seed's setup.py not being able to import django. As you can see from the earlier output of the command, Django 1.8 is installed in the VE before django-seed is requested so I am not sure why the import fails.

Error with content_type ForeignKey

django_seed.exceptions.SeederException: Field product.QASection.content_type cannot be null

Unrecognized Arguments: --number

I just installed this lib and tried to create some fake data with the command provided by the documentation. But it fails with the following error:

python manage.py seed member --number=15
usage: manage.py seed [-h] [--version] [-v {0,1,2,3}] [--settings SETTINGS]

manage.py seed: error: unrecognized arguments: --number=15

Any idea what's going on?

django-seed Version: 0.1.6
Django: 1.10.2
Python: 3.5

UUID issue

I use UUIDField as primary key for my models:

id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)

If I run seed manage command it can't handle it and tries to create all records with the same uuid.

Field cannot be null, but actually, it can.

I got this exception

django_seed.exceptions.SeederException: Field myapp.MyModel.description cannot be null

everytime I run command:

python manage.py seed myapp

model definition

class MyModel(models.Model):
    description = models.TextField('description', blank=True, null=True, default=None)

Any ideas? Thank you.

(using Django 1.8.3, Python 2.7.6, django-seed 0.1.3)

Enhancement list

This is just a list of features that I should look into

• Fields that have choices should have one chosen from the options
• Option to clean a table before starting execution
• Regression in many-to-many

any way to generate fake user data to populate test database?

Is there an example of how django-seed can generate fake users to populate test database?

I have a django app called trainers in which I implement login / logout API's, and inside this app I created a serializer for the User model imported from django.contrib.auth.models

When I ran python manage.py seed trainers --number=15, I get django_seed.exceptions.SeederException: No classed found. Did you add entities to the Seeder? Is there an entity step I'm missing to be able to generate data for Django's User model? If so, how would one go about adding this entity to the Seeder?

Problems with model inheritance

django-seed seems to ignore the fields in the base model when I try to seed them. It seeds the fields on the inherited model correctly but when it tries to save the model it throws an error because the fields on the base model are not filled.

I'll take a look at this later and see if I can fix this.

It might be useful to add Proxy models to the tests as well.

How ignore duplicates?

Hi, have a way to ignore duplicates?

Without use IntegrityError.

try:
    # code
except django.db.utils.IntegrityError:
    pass

django.db.utils.IntegrityError: duplicate key value violates unique constraint "core_response_application_id_campaign_id_userId_86e1adfd_uniq"

Thanks!

requirements are not up-to-date

requirements.txt or README does not mention the following packages which are required to run tests:

• coverage
• django-nose
• nose

This causes errors when executing python runtests.py

All cases corresponding to =or> have been put in, but the same error occurs. I think raise error occurs because it is not filtered from if at guessers.py.

I know that this is because it is an old version. Can you tell me how I can handle this with hardcoding?

I already checked the link below.

remove warning suppression in management command for non-timezone aware datetimes

The management command file management/commands/seed.py suppressed warning for non-timezone aware date times which is not documented or can simply be undesirable in outputs. Instead, the warnings should be shown and / or timezone support should be added for faked date time fields.

Same data are created when using add_entity method

Getting unexpected SeederException for BooleanField

I have a models file with the following field:

I also have also overriden the save method in this model as follows

This is my test case. After seeder.excute() some models, I cannot create this model instance without set created_at field, because turn_off_auto_add update filed attr but not recovery.

class MyModel(models.Model):
    name = models.CharField(max_length=255)
    created_at = models.DateTimeField(auto_now=False, auto_now_add=True)


class MyTest(TestCase):

    def test(self):
        faker = fake
        seeder = Seeder(faker)
        MyModel.objects.create(name='1')  # no error
        seeder.add_entity(MyModel, 1)
        MyModel.objects.create(name='2')  # no error
        seeder.execute()
        # error: django.db.utils.IntegrityError: NOT NULL constraint failed: django_seed_mymodel.created_at
        MyModel.objects.create(name='3')

        manager = self.model.objects.db_manager(using=using)
        turn_off_auto_add(manager.model) # only turn off but not recovery

        # max length restriction check
        for data_field in faker_data:
            field = self.model._meta.get_field(data_field)

            if field.max_length and isinstance(faker_data[data_field], str):
                faker_data[data_field] = faker_data[data_field][:field.max_length]

                    getattr(obj, field).add(related_obj)

        return obj.pk
