Trouble with Rails ActiveRecord relationships and adding a record for one model within another models view

I put all the code in this gist because I can't get the formatting to work.

https://gist.github.com/anonymous/72e66308c236a0277943

What I am trying to do is to have a form for the prof_comments model on the Professors page.

Whenever I try and submit the form I currently have for the prof_comments model, it tries to post to the current professors show page (/professors/1)

I've been trying to follow the following StackOverflow posts, but no luck yet.

Rails: Show form from different model in a view

Possible to add a form into another models view in rails

Routes.rb

Rails.application.routes.draw do


  root :to => "welcome#index"
  devise_for :users
  resources :users

  resources :professors
  resources :prof_comments
  resources :classes
  resources :class_comments

end

I'm not sure about the approach you were trying but this will do exactly what you are trying to do: have the professor's comments appear under it's show page.

You can nest prof_comments under professors

your routs will look like this: 

resources :professors do 
   resources :prof_comments, shallow: true
end

prof_comments controller: 

 def create 
    @professor = Professor.find(params[:id]) #this pulls specific professor by :id
    @prof_comment = @professor.prof_comments.create(prof_comment_params)
    redirect_to professor_path(@professor) # this will rout you to professor's show page once the comment is created. 
    end
 end

in app/views/professors/show.html

 h2>Add a comment:</h2>
  <%= form_for([@professor, @professor.prof_comments.build]) do |f| %>

   <%= f.label :commenter %><br> #commenter with the actual attribute_name
   <%= f.text_field :commenter %> #commenter with the actual attribute_name

   <%= f.label :body %><br> #body should be replaced with your actual attribute_name
   <%= f.text_area :body %> #body should be replaced with your actual attribute_name

   <%= f.submit %>

<% end %>

these comments will appear under the professor show view. the comments are nested under it. Treat the professor's controller as usual. you'll be using to create the comments using prof_comments controller.
