Can't use ransack on a field called "item_type"

[fernandomm]

Hi,

I have a field called item_type on a model called Version. When i try to use this:

<%= f.text_field :item_type_cont, :class => "input-medium search-query" %>

It throws an exception:

uninitialized constant Version::Item

It works fine for other fields. Any ideas of why this happens?

Thanks.

Which version of Ransack is this happening in?

Do you have a test Rails application that I can take a look at and
duplicate this problem?

I'm having the same issue with Rails 3.2.8, ruby 1.9.3 and Ransack 0.7.0. I'm trying to search id and type fields of a polymorphic model. For instance, the model is called DataError and has an errorable_id and errorable_type field. Attempting to search either of them gets a NameError: uninitialized constant DataError::Errorable

Do you have a dummy application that reproduces this issue? This would aid
us greatly in tracking down what is causing this issue.

Sure thing.

I'm having the same issue... Any news on that?

[ascoppa]

Same here 👎

Has anyone figured out a solution for this (or at least a workaround)?

Thanks

I had the same issue and I found a WA: remove association from polymorphic model:

class Comment < ActiveRecord::Base
  # belongs_to :subject, polymorphic: true
end

It seems, that error occurs in view layer, I mean that

Comment.search(:subject_type_eq => "Article")

with uncommented belongs_to :subject works.

@radar, I wrote a test for this: #312

I figured out this strange behavior. For example, I have in my form:

<%= f.text_field :notable_type_cont %>

This line calls respond_to? method in Ransack::Search and passes "notable_type_cont_before_type_cast" as first argument. Then it calls attribute_method? in Ransack::Nodes::Grouping. In this method before processing it strips unnecessary info from string. So in case when I do

Note.search(notable_type_cont: "Article")

string "notable_type_cont" became "notable_type". In first form case it doesn't happen because of "_before_type_cast".

So I think when it calls attribute_method? in Ransack::Context the string should look like notable_type, not notable_type_cont_before_type_cast.

@radar I wrote a fix for that, but I'm not sure if I'm doing right thing. Can you see it? #313

Looks like this was the same error I was experiencing over here: #173 (comment)
