Question

In my app it was User model without ‘name’ field, when I added this field by migration. On my localhost my sign up form works fine, but on heroku I have this log:

ActionView::Template::Error (undefined method `name' for #<User:0x0000000518fb00>):
Rendered users/new.html.haml within layouts/application (3.1ms)
     5:       = f.input :name, required: 'true'
     6:       = f.input :email, required: 'true'
     3:     %h1 Sign up
     4:     = simple_form_for @user do |f|
     7:       = f.input :password
     8:       = f.input :password_confirmation, required: 'true'

What I’ve tried:

heroku run rake db:migrate
heroku run rake db:reset

but nothing helped.

Answer 1

you also have to restart heroku after migrating – you’d want to run

heroku run rake db:migrate
heroku restart
