HAML Issues

[Brian Haberer]

I'm having trouble converting an existing project over to haml.

After adding the haml gem to my environment.rb and converting all my erb files to haml per the README caveat (Re HAML clashing with ERB) I'm now getting the following issue on any pages with a facebook_sign_(in||out)_link call.

NoMethodError in Home#index

Showing app/views/layouts/application.html.haml where line #19 raised:

undefined method `<<' for #Haml::Helpers::ErrorReturn:0xb63fbc98
Extracted source (around line #19):

 16:         .fb_card_info
 17:           - if current_user_admin?
 18:             = link_to 'A', admin_path, :class => 'sign_out', :style => 'float: right;'
 19:           = facebook_sign_out_link :user, :v => '2', :size => :small
 20:           %span= current_user.name
 21:     - else
 22:       = facebook_sign_in_link :user, :v => '2', :size => :small

If you know what might be causing this, or if I need to do anything beyond simply removing all ERB files from my project, please let me know.

It works fine with Haml 2.x. In Haml 3.x you need to update "facebook_sign_in_link method" in lib/devise_facebook_connectable/view_helpers.rb and most likely change "<<" in line 68 to "+".

[Brian Haberer]

Changing the method to + on the various relevant lines didn't do anything, but down ranking the version of the HAML gem to 2.2.24 seems to have done the trick.

Thanks for the tip!

Here's a patch that solves the problem of running this gem with Haml 3: szimek/devise_facebook_connectable@133fabb

I can confirm that this fixes the issue, I've been using it for a few days.

Thanks Szimek.
