Generating the Devise Views: NoMethodError in Devise/registrations#new
I have been following along just fine up until this point. As this video started I generated the devise views without a problem using rails generate devise:views.
I then open up the file app/views/devise/registrations/new.html.erb
I added the 3 lines for first_name, last_name, and profile_name to the top of the file just like Jason does using the text_field form field for each of them. I checked this part carefully for typos several times.
I then saved the file, started the server, and went to the sign_up page and noticed that it says I am already signed in so I tried in a different browser. When I go to the url http://localhost:3000/users/sign_up in a different browser I get the following error message:
NoMethodError in Devise/registrations#new
undefined method `first_name' for #<User:0x31e3438>
Extracted source (around line #7):
4: <%= devise_error_messages! %> 5: 6: <div><%= f.label :first_name %><br /> 7: <%= f.text_field :first_name %></div> 8: 9: <div><%= f.label :last_name %><br /> 10: <%= f.text_field :last_name %></div>
Just trying some things, I changed all 3 of them from text_fields to password_fields and the form loads just fine.
I also downloaded the project code and replaced my code. Still the same error.
I am using the latest versions of everything and I am on a Windows 7 platform.
If anyone knows what could be going on please let me know.

I'm pretty sure I also remember those fields get replaced with other instance variable if you keep watching.
Yes the first thing I did was migrate my db. Yeah I would keep watching, but I want to get this working before I move on. It most likely has something to do with a Ruby version, Rails version, or my system setup. I even went back and started from the first video again and I am still getting the same error at that part.

Ah I see yeah, Brett keep watching and Jim will migrate his db and will run into the same errors and from there explains how to get around these errors.
Alright, I will give it a try and hopefully fix the error so I can go back and follow along with him.
Could you please let me know what section he runs into errors.
I took the code from stage 2 and started stage 3 fresh again and did not run into the problem. I wish I found out what it was, but at least I can move on now. Thanks for the help!
I am having similar problem on stage 3
