This guide covers using a custom authentication setup with Spree, such as one provided by your own application. This is ideal in situations where you want to handle the sign-in or sign-up flow of your application uniquely, outside the realms of what would be possible with Spree. After reading this guide, you will be familiar with:
- Setting up Spree to work with your custom authentication
This guide assumes that you have a pre-existing model inside your
application that represents the users of your application already. This
model could be provided by gems such as
Devise. This guide also assumes
that the application that this
User model exists in is already a Spree
This model does not need to be called
User, but for the purposes
of this guide the model we will be referring to will be called
User. If your model is called something else, do some mental
substitution wherever you see
To begin using your custom
User class, you must first edit Spree’s
initializer located at
config/initializers/spree.rb by changing this
Spree.user_class = 'Spree::User'
Spree.user_class = 'User'
Next, you need to run the custom user generator for Spree which will
create two files. The first is a migration that will add the necessary
Spree fields to your users table, and the second is an extension that
lib/spree/authentication_helpers.rb to the
Spree::Core::AuthenticationHelpers module inside of Spree.
Run this generator with this command:
bundle exec rails g spree:custom_user User
This will tell the generator that you want to use the
User class as
the class that represents users in Spree. Run the new migration by
bundle exec rails db:migrate
Next you will need to define some methods to tell Spree where to find your application’s authentication routes.
There are some authentication helpers of Spree’s that you will need to
possibly override. The file at
contains the following code to help you do that:
module Spree module AuthenticationHelpers def self.included(receiver) receiver.send :helper_method, :spree_login_path receiver.send :helper_method, :spree_signup_path receiver.send :helper_method, :spree_logout_path receiver.send :helper_method, :spree_current_user end def spree_current_user current_user end def spree_login_path main_app.login_path end def spree_signup_path main_app.signup_path end def spree_logout_path main_app.logout_path end end end
ApplicationController add those lines:
include Spree::AuthenticationHelpers include Spree::Core::ControllerHelpers::Auth include Spree::Core::ControllerHelpers::Common include Spree::Core::ControllerHelpers::Order include Spree::Core::ControllerHelpers::Store helper 'spree/base'
Each of the methods defined in this module return values that are the most common in Rails applications today, but you may need to customize them. In order, they are:
spree_current_userUsed to tell Spree what the current user of a request is.
spree_login_pathThe location of the login/sign in form in your application.
spree_signup_pathThe location of the sign up form in your application.
spree_logout_pathThe location of the logout feature of your application.
URLs inside the
spree_logout_path methods must have
main_app prefixed if they
are inside your application. This is because Spree will otherwise
attempt to route to a
inside of itself, which does not exist. By prefixing with
you tell it to look at the application's routes.
You will need to define the
logout_path routes yourself, by using code like this inside your
config/routes.rb if you’re using Devise:
devise_for :users devise_scope :user do get '/login', to: "devise/sessions#new" get '/signup', to: "devise/registrations#new" delete '/logout', to: "devise/sessions#destroy" end
Of course, this code will be different if you’re not using Devise.
Simply do not use the
devise_scope method and change the controllers
and actions for these routes.
You can also customize the
spree_logout_path methods inside
lib/spree/authentication_helpers.rb to use the routing helper methods
already provided by the authentication setup you have, if you wish.
Any modifications made to
while the server is running will require a restart, as wth any other
modification to other files in
In your User Model you have to add:
include Spree::UserMethods include Spree::UserAddress include Spree::UserPaymentSource
The first of these methods are the ones added for the
spree_roles. This association will retrieve all the roles that
a user has for Spree.
The second of these is the
spree_orders association. This will return
all orders associated with the user in Spree. There’s also a
last_incomplete_spree_order method which will return the last
incomplete spree order for the user. This is used internal to Spree to
persist order data across a user’s login sessions.
The third and fourth associations are for address information for a user. When a user places an order, the address information for that order will be linked to that user so that it is available for subsequent orders.
The next method is one called
has_spree_role? which can be used to
check if a user has a specific role. This method is used internally to
Spree to check if the user is authorized to perform specific actions,
such as accessing the admin section. Admin users of your system should
be assigned the Spree admin role, like this:
user = User.find_by(email: '[email protected]') user.spree_roles << Spree::Role.where(name: 'admin').first_or_create
To test that this has worked, use the
has_spree_role? method, like
If this returns
true, then the user has admin permissions within
Finally, if you are using the API component of Spree, there are more
methods added. The first is the
spree_api_key getter and setter
methods, used for the API key that is used with Spree. The next two
which will generate and clear the Spree API key respectively.
This is only applicable for Spree 4.0 and older. Spree 4.1 and newer releases handle this out of the box.
To make the login link appear on Spree pages, you will need to modify
spree/shared/_nav_bar.html.erb file which you can copy over from Spree codebase
to your project (detailed in View Customization section).
You will need to add this code:
<%% if try_spree_current_user %> <li> <%%= link_to Spree.t(:logout), spree_logout_path, method: :delete %> </li> <%% else %> <li> <%%= link_to Spree.t(:login), spree_login_path %> </li> <li> <%%= link_to Spree.t(:sign_up), spree_signup_path %> </li> <%% end %>
This will then use the URL helpers you have defined in
lib/spree/authentication_helpers.rb to define three links, one to
allow users to logout, one to allow them to login, and one to allow them
to signup. These links will be visible on all customer-facing pages of
In Spree, there is a promotion that acts on the user signup which will not work correctly automatically when you’re not using the standard authentication method with Spree. To fix this, you will need to trigger this event after a user has successfully signed up in your application by setting a session variable after successful signup in whatever controller deals with user signup:
session[:spree_user_signup] = true
This line will cause the Spree event notifiers to be notified of this event and to apply any promotions to an order that are triggered once a user signs up.
