Question

I’m creating a profile that is associated with a member id based on Devise authentication.

When creating the profile, the values aren’t inserted into the database.

Routes file.

  resources :troopers do
     resource :trooper_profile
  end

Trooper model

has_one :trooper_profile 

Trooper Profile model

belongs_to :trooper

Trooper Controller #create action

  def create
 @trooper = current_trooper
 @profile = @trooper.build_trooper_profile(params[:profile])  
 respond_to do |format|
   if @profile.save
     format.html { redirect_to(trooper_trooper_profile_path, :notice => 'Profile was successfully created.') }
   else
     format.html { render :action => "new" }
   end
 end

end

Profile Form

<%= form_for @profile, :url => trooper_trooper_profile_path(@trooper) do |f| %>
<%= f.label :first_name %><br />
<%= f.text_field :first_name %><br /><br />
<%= f.label :last_name %><br />
<%= f.text_field :last_name %><br /><br />
<p><%= submit_tag "Create Profile" %></p>
<% end %>

I’ve got this same setup in another application and can’t see why this isn’t working.

Change the following…

@profile = @trooper.build_trooper_profile(params[:trooper_profile]) 

It appears the parameters being passed are :trooper_profile

trooper_profile"=>{"first_name"=>"Robert", "last_name"=>"", "commit"=>"Create Profile", "trooper_id"=>"1"}

However, you’re referencing :profile
