NoMethodError in Devise::Registrations#new

I'm working on rails project and have couple of issues with the new version of Bootstrap. When I install Devise and put columns of first, last and profile name on new.html.erb file, I've got error message and wasn't able to figure how to solve. ```

<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %> <%= devise_error_messages! %>

<div class="field"> <div><%= f.label :first_name %><br /> <%= f.text_field :first_name %></div>

<div><%= f.label :last_name %><br /> <%= f.text_field :last_name %></div>

<div><%= f.label :profile_name %><br /> <%= f.text_field :profile_name %></div> </div>

Error Message:
NoMethodError in Devise::Registrations#new
undefined method `first_name' for #<User:0x007feb75a8a1e8>
 <%= f.text_field :first_name %></div>

You have to show us the whole file, it's impossible to tell what's wrong by looking at those 4 lines.

Hi Maciej, good point. I moved the files to github. https://github.com/sarahkwak/cookiebook.git

The issue file is: app/views/devise/registrations/new.html.erb

Your User schema does not have the attributes you mention here, like first, last and profile name. You have to run rake db:migrate to apply the migrations and get those attributes. Also, I see you're using Rails 4.1.6. Bear in mind that this course will not be easy if you're not using version 3.2.

If you did run it and they still don't show up, it means you did the rake db:migrate and then modified the user migration. If you, you'd need to do rake db:reset to delete the whole database and remake it using all the migrations from scratch.

Thanks Maciej, I've gone through the workaround link you've posted but found that there are still several issues. I think I will just reset and delete the whole database and remake it. Thanks anyway!!
