在Devise上注册时堆栈级别太深

Question

I am currently getting an error while registering with devise. When I press submit on the sign up form, I am redirected to /users with this error:

SystemStackError in Devise::RegistrationsController#create stack level too deep

Rails.root: /Users/user/Desktop/Programming/Rails/Site

Request

Parameters:

{"utf8"=>"✓",
 "authenticity_token"=>"VTOUFUYrYxUD0sJpdCz5Mpn6Dvyf7CVqUjj5oDSIqf8=",
 "user"=>{"email"=>"example@gmail.com",
 "password"=>"[FILTERED]",
 "password_confirmation"=>"[FILTERED]"},
 "commit"=>"Sign up"}

I have read other people having similar problems, but none of their solutions have worked. Here is what I had tried: Running a migration, and checking for infinite recursion in routes.rb

Gems:

gem 'pg'

gem 'forem', :github => "radar/forem", :branch => "rails4"
gem 'forem-bootstrap', :github => "radar/forem-bootstrap", :branch => "master"

gem 'devise', '3.0.0'
gem 'kaminari'
gem 'friendly_id', github: "FriendlyId/friendly_id"
gem 'cancan'

gem "therubyracer"
gem "less-rails"
gem "twitter-bootstrap-rails"


gem 'twitter-bootstrap-rails'

gem 'rails_12factor', group: :production

This error generally happens when you accidentally recursively changing an attribute. If you have a xyz attribute in User model, and a virtual attribute named xyz, that is directly changing the xyz, you end up calling the virtual, the virtual calls the virtual again and so on.. Therefore, take a look on whether something like that happens somewhere in your code.
