Simply adding the simple_form gem to my Rails app wasn't enough to get an error; can you provide steps to reproduce this?

[seanlinsley]

I'm pruning inactive issues right now, so I'm going to close this ticket. Please feel free to post more information if you're still experiencing this.

I'm having the same issue using the following gems:

gem 'rails',                '4.0.1'

gem 'activeadmin',          github: 'gregbell/active_admin'
gem 'simple_form',          '~> 3.0.0'

@seanlinsley just adding the simple_form gem does not cause the issue, you need to have its initializer too.

[sashazykov]

Sorry, it was a new project and I had to move to formtastic, so I can't reproduce the error now.

[tgautier]

If you need any more details or anything please let me know. I'd be happy to contribute in any way.

[seanlinsley]

I ran the simple_form generator this time, and tried reproducing this in both Rails 3.2.15 and 4.0.1, but couldn't get any error to occur. @tgautier could you provide reproduction steps, or could you upload a Rails app to GitHub that has this problem?

[tgautier]

Here's a gist https://gist.github.com/tgautier/227dc5fe65427ff9f5ef with the error log I get with the above Gemfile and my two simple_form initializers.

Without the initializers active_admin is working as expected.

I don't know if this is related but I was already using devise with a User model before I tried to add active_admin. I've just ran the active_admin generator with the default AdminUer.

Oh, the problem is pretty obvious:

inputs = %w[
  CollectionSelectInput
  DateTimeInput
  FileInput
  GroupedCollectionSelectInput
  NumericInput
  PasswordInput
  RangeInput
  StringInput
  TextInput
]

inputs.each do |input_type|
  superclass = "SimpleForm::Inputs::#{input_type}".constantize

  new_class = Class.new(superclass) do
    def input_html_classes
      super.push('form-control')
    end
  end

  Object.const_set(input_type, new_class)
end

Formtastic looks up your custom input classes in the root namespace, just like it appears that simple_form does from your code above.

I feel quite dumb, I didn't really know about formstatic insides.

I've refactored this part and it works. Thanks !

[seanlinsley]

Awesome :)

For others that come across this problem later on, how exactly did you solve this?

Facing this problem. @tgautier Kindly update your gist.
