rabl may be interfering with finding html templates (Rails 3.2.2)

[tolsen]

Rails 3.2.2 appears to have made things worse. While trying to render an html page, Rails seems to be insisting on trying to find a json template:

Template is missing

Missing template quarks/index with {:locale=>[:en], :formats=>[:json], :handlers=>[:erb, :builder, :coffee, :haml, :rabl]}. Searched in: * "/Users/tim/git/surround-release2/app/views" * "/Users/tim/.rvm/gems/ruby-1.9.3-p0/gems/devise-2.0.4/app/views" 

The controller action has a respond_to block with format.html and format.json defined.

The problem goes away if I remove rabl so I suspect some weird rabl interaction with regard to registering. Also, this problem did not happen in Rails 3.2.1.

This seems related: rails/rails@19433ce

In my case I found out that when using render template using rabl within another (html) layout, like for instance:

<%= render(template: 'users/current_user', formats: [:json], handlers: [:rabl]).html_safe %>

any following call to render insists on json, so I had to make the format explicit again there:

<%= render(partial: 'foo/bar', formats: [:html]) %> 

Maybe this is just the way it works in Rails now...

I had a bitch of a time finding all the other renderings in my massive list of partials (client-side heavy, lots of template partials).

So I added this to my helpers:

def with_format(format, &block)
  old_formats = formats
  self.formats = [format]
  result = block.call
  self.formats = old_formats
  result
end

• partially compiled from reading this and this.

Then I had a file like show.html.erb render this:

<%= render partial: "foo/bar", formats: :js, locals: { baz: baz } %>

Which then switches formats to JSON which bombs without the helper:

var test = <%= with_format(:json) { render(template: 'v1/recipes/show', formats: :json).html_safe } %>;

So the formats goes from :html to :json, renders out the RABL, and then back to :html

The formats: :json halts deprecation warnings.

GOOD NEWS 👏 👏 👏 ... There is a fix in 3.2 stable (unreleased):
rails/rails#5440
commit with tests!

Also, I added your comments to https://github.com/nesquena/rabl/wiki/RABL-and-Rails-3.2 thanks @carhartl

FYI, Rails 3.2.3 does include the fix and you won't get template not found errors anymore even if the output format is different.

Hi,
I still see this issue with rails 3.2.3 and ruby 1.9.3, but only with index page

Example:
Don't work
http://localhost:3000/api/projects.json

Error:

MissingTemplate (Missing template api/projects/index, application/index with {:locale=>[:en], :formats=>[:json], :handlers=>[:erb, :builder, :coffee, :rabl]}

Works!
http://localhost:3000/api/projects/1.json

What the code you're rending with?

I too having this issue:

respond_to do |format|
  format.html do
    render :template => "main/index"
  end
  format.json do
    render :status => 200 , :json => {:success => true, :explore =>  'some-data' }
  end
end

When i hit explore.json
It gives me...

Template is missing

Missing template main/index with {:handlers=>[:erb, :builder, :coffee, :rabl, :haml], :formats=>[:json], :locale=>[:en, :en]}. Searched in: * "D:/app/app/views" * "C:/Ruby/lib/ruby/gems/1.9.1/gems/devise-2.1.2/app/views" * "C:/Ruby/lib/ruby/gems/1.9.1/bundler/gems/rails_admin_tag_list-ca103dbca58e/app/views" * "C:/Ruby/lib/ruby/gems/1.9.1/bundler/gems/rails_admin-3684bd706770/app/views" * "C:/Ruby/lib/ruby/gems/1.9.1/gems/kaminari-0.14.1/app/views"

RABL is interfering in default handlers

I'm seeing this issue with rabl-0.8.5, rails 3.2.13 and ruby 1.9.3p194

must force format to :json, default format not working with :index method (other's are good)

GET /companies - template not found
GET /companies.json - template found
