Rails 4 + Devise DB Sign In: NoMethodError `login' for ActionDispatch::Request

Question

I'm having what I believe is the same issue as this user. I've also seen this error with "email" instead of "login" before I configured to allow username based sign in.

I can create a user fine. The user just can't sign in. Here are some key variables from config/initializers/devise.rb:

config.authentication_keys = [ :login ]
config.request_keys = [ :login ]
config.http_authenticatable = [false]

Here is the form from controllers/sessions/new.html.erb

<%= form_for(resource, as: resource_name, url: session_path(resource_name)) do |f| %>
  <div><%= f.label :login %><br />
  <%= f.email_field :login, autofocus: true %></div>

  <div><%= f.label :password %><br />
  <%= f.password_field :password, autocomplete: "off" %></div>

  <% if devise_mapping.rememberable? -%>
     <div><%= f.check_box :remember_me %> <%= f.label :remember_me %></div>
 <% end -%>

 <div><%= f.submit "Log in" %></div>
 <% end %>

Here are the parameters submitted:

{"utf8"=>"✓", 
    "authenticity_token"=>"yada",
    "user"=>{"login"=>"[email protected]", 
      "password"=>"[FILTERED]", 
      "remember_me"=>"0"}, 
    "commit"=>"Log in"}

rails 4.1, devise 3.4

Backtrace:

Any ideas?

Answer 1

You use a virtual attribute called login as the authentication key. What's missing is overriding Devise's find_for_database_authentication
