Could not find devise mapping for path "/sessions/user" devise log in error
Solution 1
in your routes.rb file, try wrapping your routes inside the scope block as the error message suggests. Here is an example:
devise_scope :user do
get "signup", to: "devise/registrations#new"
get "login", to: "devise/sessions#new"
get "logout", to: "devise/sessions#destroy"
end
This will give you nicely named routes.
And by the way, if you are using Rails 4, get rid of the match method. you need to specify the HTTP verb.
OBSOLETE old answer:
(Below is the old obsolete version of the code, shown for reference. Use the code above.)
devise_for :users, path_names: { sign_in: 'login', sign_out: 'logout', sign_up: 'signup' }
AND
match '/sessions/user', to: 'devise/sessions#create', via: :post
Solution 2
Be careful if you nave namespaced routes to declare the devise_scope a little different:
namespace :api, defaults: {format: 'json'} do
namespace :v1 do
devise_scope :api_v1_user do
...
end
end
end
Solution 3
This error (AbstractController::ActionNotFound - Could not find devise mapping for path) can arise if devise_scope is passed a plural scope instead of a singular scope.
The devise_for method takes a plural form of model scope (i.e. :users) whereas the devise_scope takes the singular form (i.e. :user).
From the devise documentations (http://www.rubydoc.info/github/plataformatec/devise/ActionDispatch%2FRouting%2FMapper%3Adevise_scope):
Also be aware of that 'devise_scope' and 'as' use the singular form of the noun where other devise route commands expect the plural form. This would be a good and working example.
devise_scope :user do get "/some/route" => "some_devise_controller" end devise_for :users
Solution 4
devise_scope :user do
# add any route which is giving above error message
end
Solution 5
Error is telling you:
devise_scope :user do
match '/sessions/user', to: 'devise/sessions#create', via: :post
end
did you try that?

Very frustrating for the last few days.
I have a rails app with Devise installed where I generated a new User model and I generated Devise views as well.
This happens when I try to sign in as an existing user right when I click "Log in" after filling out the email and password fields:
AbstractController::ActionNotFound - Could not find devise mapping for path "/sessions/user". This may happen for two reasons: 1) You forgot to wrap your route inside the scope block. For example: devise_scope :user do get "/some/route" => "some_devise_controller" end 2) You are testing a Devise controller bypassing the router. If so, you can explicitly tell Devise which mapping to use: @request.env["devise.mapping"] = Devise.mappings[:user] : devise (3.2.4) app/controllers/devise_controller.rb:84:in `unknown_action!' devise

I can fill in the appropriate fields, click "Sign up" and it notifies me that I've logged in successfully and redirects me to the root URL showing the user as logged in. The error only occurs when I try to log in.
Here are my routes:
