I'm trying to figure out how to use wisper with Devise.
When a new user account is registered, I want to create some sample data for that user.
So in my user model I would have:
include Wisper::Publisher
after_create :notify
def notify
publish(:user_created, self)
end
and my listener would be something like:
class SampleDataCreator
def user_created(user)
user.widgets.create!(name: "Your First Widget")
end
end
But I can't figure out how to tie this into Devise. How can I configure the SampleDataCreator to listen for events from the Devise user model?
UPDATE
I've tried attaching the listener in the Devise registration controller as follows:
class RegistrationsController < Devise::RegistrationsController
def create
super do |resource|
resource.subscribe(SampleDataCreator.new)
end
end
end
but it seems the listener never gets triggered.
UPDATE 2
I realised the above approach wasn't working because the record is saved before yield is called. It seems tricky to hook into Devise before this point, so instead I overrode the whole method:
def create
build_resource(sign_up_params)
resource_saved = resource.save
yield resource if block_given?
resource.subscribe(SampleDataCreator.new) # <-------------------- my addition
if resource_saved
if resource.active_for_authentication?
set_flash_message :notice, :signed_up if is_flashing_format?
sign_up(resource_name, resource)
respond_with resource, location: after_sign_up_path_for(resource)
else
set_flash_message :notice, :"signed_up_but_#{resource.inactive_message}" if is_flashing_format?
expire_data_after_sign_in!
respond_with resource, location: after_inactive_sign_up_path_for(resource)
end
else
clean_up_passwords resource
respond_with resource
end
end
This now works, although it's not very elegant.
UPDATE 3
I found a much simpler way, I can just hook into build_resource:
class RegistrationsController < Devise::RegistrationsController
def build_resource(sign_up_params)
super.subscribe(SampleDataCreator.new)
end
end
