Knock: login without email

[ernandejr]

My application logs in with username, how can I generate the token with username instead of email?

You can modify the default behavior implementing within your entity model a class method from_token_request that takes the request in argument.

class User < ActiveRecord::Base
  def self.from_token_request(request)
    username = request.params["auth"] && request.params["auth"]["username"]
    self.find_by(username: username)
  end
end

You might also need to override strong parameters:

app/controllers/user_token_controller.rb

class UserTokenController < Knock::AuthTokenController

  private

  def auth_params
    params.require(:auth).permit(:username, :password)
  end
end

app/models/user.rb

class User < ActiveRecord::Base
  def self.from_token_request(request)
    username = request.params["auth"] && request.params["auth"]["username"]
    self.find_by(username: username)
  end
end

I’m also using a username and no emails. What about making this configurable?
