This post is an extension of Abhijit's article here - http://kiprosh.com/blog/180(Customizing Devise authentication, to disable or enable user authentication.)
It helped me to add further customization to check if user has active chargify_subscription and then only proceed to login otherwise show custom message instead of default devise message.
Here is what we did (2 step process).
- In our user model (specifically user_extensions) override devise method active_for_authentication as follows
def active_for_authentication? super && !is_locked && active_subscription? end
Calling super first is very important here, to have devise perform all its regular checks first and then upon success we can proceed to add our custom checks.
is_locked is a flag and active_subscription? is a user instance method in our model that checks if user has active subscription in Chargify.
In the above code, we have added custom checks "is_locked" and then "active_subscription?"
Accordingly we also show custom message to user based on the user's lock or subscription state. To do so, override method "inactive_message".
- In our user model (specifically user_extensions) override devise method inactive_message as follows
def inactive_message return :unauthorised unless active_subscription? !is_locked ? super : :is_locked end
Here :unauthorised is a custom message in our config/locales/devise.en.yml as follows
devise: failure: already_authenticated: 'You are already signed in.' unauthenticated: 'You need to sign in or sign up before continuing.' unconfirmed: 'You have to confirm your account before continuing.' invalid: 'Invalid email or password.' is_locked: 'Your account has been locked. Please contact owner of this account.' unauthorised: "You do not have an active subscription. Please subscribe to log in to your account."
