Add RJS, Prototype, and Scriptaculous helpers to Rails 3.1+ apps

prototype-rails provides Prototype, Scriptaculous, and RJS on Rails 3.1 and later.

Prototype and Scriptaculous are pulled in by the asset pipeline, so you don't need to copy the source files into your app. You may reference them in your s app/assets/javascripts/application.js:

//= require prototype
//= require prototype_ujs
//= require effects
//= require dragdrop
//= require controls

prototype-rails supports RJS debugging. RJS responses are wrapped to catch exceptions, alert() them, and re-raise the exception. Debugging is disabled by default. To enable in development, set config.action_view.debug_rjs = true in config/environments/development.rb.

Support for Rails 4.1 and above

Unfortunately, due to limited manpower and resources, the Rails core team has not been able to confirm if this gem currently works with Rails 4.1 and above. If you have found any problems while upgrading your application, please report them at the issue tracker, or better yet, submit patches by sending a pull request.

In any case, this gem will NOT be officially supported on Rails 5.0 and above.

Add License information to Gemspec

This will make it show up on rubygems.org. I'm doing due diligence on our gems and need to find out the licenses for all the gems. Having it show up on rubygems.org cuts out the step of having to go to the github repo.

Does not looks compatible with Rails 3.1.0rc2

When trying to start Rails I am getting the following error:

flash message not displaying while using the rcs

Hi,
rcs file is loaded,but the flash message is not loaded properly.
The content of the rcs file is below

#page['ajax-indicator'].set_style :display => ''
data = @DaTa || :data
output = @output || :output
#page.alert(page[:subject_form])
#page[:subject_form].reset()
if @successful
page[data].replace_html :partial => @partial_render
page[output].replace_html flash_messages
else
if(flash[:notice] or flash[:error])
page[output].replace_html flash_messages
else
page[output].replace_html error_messages_for @model
end
end

#page.visual_effect :fade, 'ajax-indicator'
#page['ajax-indicator'].set_style :display => 'none'

The output for adding I got as follow

$("data").update("\n\u003cp class='info'\u003eNo data to display\u003c/p\u003e\n\n");
$("output").update("\u003cp class='success'\u003eNew activity is added successfully\u003c/p\u003e\u003cbr\u003e");
new Effect.Fade("ajax-indicator",{});

But I want this output with flash with appropriate image.

Kindly help me to resolve this issue.

cannot load such file -- action_view/vendor/html-scanner (LoadError)

Hello,
I am upgrading rails application to 4.2 and i am facing html-scanner issue when attempting to start the webrick server.
I found that the issue is causing with prototype-rails gem from other blogs and I tried updating my Gemfile with below line.

After I add this line, bundle install and restart the server, server starts fine but none of the assets are loading in the UI when I navigate to localhost:3000.
Any suggestions on this issue would be appreciated!!

Below is some more details of the error

undefined method `debug_rjs=' for ActionView::Base:Class

Prototype.js library 1.7.1 or 1.7.2 or higher

We were wondering if there any any plans to update the Prototype.js library (1.7) to the latest versions?

Thanks

ActiveSupport::JSON::Variable is deprecated in Rails edge

it is used in prototype_helper.rb

Not running with 3.1.1

I'm trying to transform a Rails 2.3.14 to 3.1.1 application.
Prototype rails should provide all the lost remote_foo..
But it doesn't work at all for me. It's like if the gem was not enable anymore.
I installed it, reinstalled it, bundle install/update, add/remove/add gem into Gemfile, test it as a plugin, everything, but I still have got this error "undefined method `remote_function' ".

The function seams to be there, into the prototype-rails gem into prototype helpers file, but my application don't see it, why ? Do you have an idea ?

uninitialized constant ActionView::Helpers::JavaScriptCollectionProxy::ActiveSupport

After upgrading to Rails 3.1rc6 I started getting this error with my RJS.

uninitialized constant ActionView::Helpers::JavaScriptCollectionProxy::ActiveSupport

Anyone else getting this? Mainly seems to be with page.select for me.

uninitialized constant AbstractController::Rendering in Rails 4.2

I'm trying to migrate an app that still uses prototype from Rails 4.1 to 4.2.

I'm using Rails 4.2.rc2.

Steps to reproduce:

rails new testapp -j prototype
cd testapp
rails s

Throws this error:

ruby/gems/2.1.0/gems/actionpack-4.2.0.rc2/lib/action_controller/base.rb:204:in `<class:Base>': uninitialized constant AbstractController::Rendering (NameError)

`require': cannot load such file -- action_view/vendor/html-scanner (LoadError)

Seems like I can't upgrade to Rails 4.2 while using prototype-rails. I've tried using the deprecated sanitizer gem (gem 'rails-deprecated_sanitizer', '~> 1.0.3') but that hasn't fixed the load error. I know this isn't technically supported, but is there any way this is fixable?

Port of prototype-rails' RJS and helpers to jquery

Based on both jrails gem and prototype-rails, I have been able to get prototype-rails replaced with its full API and using jquery with everything working: RJS and its helpers and other helpers from prototype-rails

The code is at: https://github.com/coletivoEITA/jrails

Could you please indicate under which license this code is available?

Conflict With ActionMailer?

While setting up actionmailer and testing it, I have been running into an error. It appears to be caused by prototype-rails, since my example works when I use jquery. I don't know enough about the internals to track the source of the bug down.

Update for rails 5.1.1

we need update of this gem for rails 5.1.1

Generated page_update javascript is incorrectly escaped.

The javascript being generated by update_page is incorrectly marked as html_safe. This causes a problem when you include an update_page fragment as an option on an HTML tag.

For example:

<%= submit_tag('Save', :disable_with => 'Please wait...', :onclick => update_page {|p| p.hide("cancel-update")}) %>

The onclick option is passed through to the tag helpers and eventually the text is processed by ERB::Util.html_escape. However, the html_escape method does not escape the string if it is marked as html_safe. All output from update_page is marked as html_safe, even though it isn't.

The output from update_page in the above example is

"Element.hide(\"cancel-update\");"

Clearly, the output has not been escaped as the " characters have not been converted -

"Element.hide("cancel-update");"

The solution is to remove the html_safe method from the output of update_page -

def update_page(&block)
  JavaScriptGenerator.new(self, &block).to_s
end

I realize that it's pretty futile raising an issue here in the hope that the official gem might be updated. However, for any other users out there with large amounts of Prototype code that can't afford to instantly convert everything to JQuery, then this might help you.

It would be nice if the Rails developers sometimes recognized that in the real world, we don't necessarily have all the resources to instantly jump on the latest bandwagon. Sadly Prototype has fallen out of favour and has now been neglected to the point where nobody bothers to fix any errors.

config.action_view.debug_rjs

I'm trying to move an app from 3.0 to 3.2. When I do so, I have to comment out the config.action_view.debug_rjs = true line otherwise I get this error:

~/.rvm/gems/ruby-1.9.3-p125@rigse/gems/actionpack-3.2.2/lib/action_view/railtie.rb:34:in block (3 levels) in <class:Railtie>': undefined methoddebug_rjs=' for ActionView::Base:Class (NoMethodError)

looking at the prototype-rails code I don't see how the config.action_view.debug_rjs = true line could work because prototype-rails doesn't seem to create the debug_rjs method anywhere.

Release 4.0.0 gem

Warning message when bundling (4.2 branch)

prototype-rails at /Users/murphy/.rvm/gems/ruby-2.1.5@schatten/bundler/gems/prototype-rails-d7c004222485 did not have a valid gemspec.
