New User sign up issues on Ruby Rails

Im having trouble with user registrations with ruby on rails, Ive had issues with following along because I got signed in and dont know how to sign out (of the treebook app thing),

I also "destroyed" a "first" user. (not sure if this is the issue (error msg:

undefined method `first_name' for #<User:0x000001038fe770>) 

 now my new text fields (on user//users/sign_up.) 
wont come up, and i get this error:

NoMethodError in Devise/registrations#new

Showing /Users/macuser/treebook/app/views/devise/registrations/new.html.erb where line #7 raised:

undefined method `first_name' for #<User:0x000001038fe770>
Extracted source (around line #7):

Thanks Jason,

But I already figured it out. But still have a question.

What I did was, miss-spell one of my new registration form text strings things in the db/migrate/ devise create user (I spelled it :comany_name instead of company_name) , saved it or did the next step in creating the data base then when I started adding the fields they wouldn't match up and I would get a no method error.

Ive gone though and got it to work, but now that field is titled "comany" instead of "company", I guess my question now is "how do I change this, to company?" or "how do I re-title a column in my users table, without screwing everything up?"

Hey Ryan,

You can add a migration and rename the column from there:

rails generate migration change_company_name

Then open the migration and add the folowing:

rename_column :users, :comany_name, :company_name

Hope that helps!
