I get an error that look like this: undefined method `post_image_will_change!' for #<Post:0xf4e9184> app/controllers/posts_controller.rb:43:in `new' app/controllers/posts_controller.rb:43:in `create' I've included this in my "post" model: attr_accessible :title, :name, :content, :post_image mount_uploader :post_image, PostImageUploader and in _form.html.erb I've added: :html => { :multipart => true } I looked CarrierWave Error but that doesn't help me.

I'm creating a multi-part form in the style that Ryan Bates describes here: http://railscasts.com/episodes/217-multistep-forms http://asciicasts.com/episodes/217-multistep-forms (text-based version) To summarize, I have one view (with a bunch of partials for each form step), and the form variables are stored in a session when the user clicks a next button and a different part of the form is displayed.

I followed this

I'm new to Rails and built something based on this http://railscasts.com/episodes/403-dynamic-forms but I have a problem with storing data in the additional fields... I have a ProductType object that has many ProductField objects. The ProductField object also belongs to a ProductType and Product object belongs to a ProductType. So,new dynamic fields can easily be added via the constructor ProductType, but when I try to set data in this fields via Product controller nothing happens. I am sure that problem is related to use strong parameters, but fix described here and here did't help. product

I've first set up a Twitter authentication, as done by Ryan himself. That worked flawlessly. I then moved on to adding a Facebook login. However, after authorizing the app the redirect to /auth/facebook/callback fails with: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed I am working on localhost.
