Ruby on rails: Devise, want to add invite code?

I would like to add a开发者_如何学JAVAn invite_code requirement for users to sign up. Ie. in addition to requiring them to specify an email/password combo, I want an additional field :invite_code. This is a temporary fix so that non-wanted users cannot login during a given alpha period.

I'm confused since Devise doesn't add controllers. I'm sort of familiar with the concept of virtual attributes, and it strikes me that I could add a :invite_code to the model, and then just hard code a step now where it says invite code must equal 12345 or whatever for now.

Does this make sense with devise authentication? And how do I go approaching this from a proper rails restful approach?

Thank you very much.


1) A virtual attribute usually needs a setter in addition to a getter.

Easiest way is to add

attr_accessor :invite_code
attr_accessible :invite_code # allow invite_code to be set via mass-assignment
    # See comment by James, below.

to the User model

2) I presume that Devise wants the User model to validate. So you could stop the validation by adding

validates_each :invite_code, :on => :create do |record, attr, value|
    record.errors.add attr, "Please enter correct invite code" unless
      value && value == "12345"
end

NOTE: added :on => :create since the invite_code is only needed for creating the new user, not for updating.


Try this: http://github.com/scambra/devise_invitable

It adds support to devise for sending invitations by email (it requires to be authenticated) and accept the invitation setting the password.

It works with Devise >= 4.0 If you want to use devise 3.0.x, you must use 1.2.1 or lower If you want to use devise 3.1.x, you must use 1.3.2 or lower If you want to use devise >= 3.2, you must use 1.6.1 or lower...


According to the docs, invitable gives you control over who gets to invites others. People cannot distribute invites if there is a "0" setting for invitation_limit.

From the docs:

invitation_limit: The number of invitations users can send. The default value of nil means users can send as many invites as they want, there is no limit for any user, invitation_limit column is not used. A setting of 0 means they can't send invitations. A setting n > 0 means they can send n invitations. You can change invitation_limit column for some users so they can send more or less invitations, even with global invitation_limit = 0.
