It seems like the Crop coordinates values are not being set.
This is what I get in my params hash after submitting:

"profile_photo"=>{"crop_x"=>"", "crop_y"=>"", "crop_w"=>"", "crop_h"=>""}, "commit"=>"Crop Photo", "user_id"=>"2", "profile_id"=>"2", "id"=>"7"}

Notice how all the crop_* are empty? What could be the reason?

I have both
attr_accessor :crop_x, :crop_y, :crop_w, :crop_h

attr_accessible :crop_x, :crop_y, :crop_w, :crop_h


I m trying to use this gem and run into some issues. I managed to get around most of them, but now I am getting a seg fault. I believe it is happening in the controller where I have this code

from [based on material from here](
@regions = Region.filter(:params => params)

``` here is the seg fault message I am getting

/home/danny/.rvm/gems/ruby-1.9.3-p362/gems/activerecord-3.2.9/lib/active_record/relation.rb:241: [BUG] Segmentation fault

Never mind, I found the issue and fixed it.


I first implemented this episode and it work. However, I am using simple_for in my project, so I switched from 'form_for' o 'simple_form_for' in the devise new registrations view.

When the user log in using Twitter, for example, they are redirected to the new registration form as eexpected, since I my project requires email and Twitter does not provide user email address.

The project is that the registration form is not pre-populated with the first and last name on first pass. However, when you lick on the 'log in with Twitter' link again, then the correct behaviour (pre-populating the first name and last name fields) happens.

My question is, how do I avoid having to click the link twice in order to get the correct behaviour?



I have tried to follow this tutorial to implement it in my own project, but I am never able to get it work. After adding the new.js.erb and adding the js code shown in the video, when I click 'Add Post' link nothing happens. I have followed the trouble shooting steps recommended by Ryan, still no dice. Although, I did get a n/w status of 304 unmodified as opposed to the 200 ok that Ryan got in the video. Any ideas as to what I am doing wrong?
