Rails: activeadmin overriding create action
Ruby on-RailsActiveadminInherited ResourcesRuby on-Rails Problem Overview
I have an activeadmin resource which has a belongs_to :user relationship.
When I create a new Instance of the model in active admin, I want to associate the currently logged in user as the user who created the instance (pretty standard stuff I'd imagine).
So... I got it working with:
controller do
def create
@item = Item.new(params[:item])
@item.user = current_curator
super
end
end
However ;) I'm just wondering how this works? I just hoped that assigning the @item variable the user and then calling super would work (and it does). I also started looking through the gem but couldn't see how it was actually working.
Any pointers would be great. I'm assuming this is something that InheritedResources gives you?
Thanks!

Solution 1 - Ruby on-Rails
I ran into a similar situation where I didn't really need to completely override the create method. I really only wanted to inject properties before save, and only on create; very similar to your example. After reading through the ActiveAdmin source, I determined that I could use before_create
to do what I needed:
ActiveAdmin.register Product do
before_create do |product|
product.creator = current_user
end
end
Solution 2 - Ruby on-Rails
Another option:
def create
params[:item].merge!({ user_id: current_curator.id })
create!
end

You are right active admin use InheritedResources
, all other tools you can see on the end of the page.
Solution 4 - Ruby on-Rails
As per the AA source code this worked for me:
controller do
def call_before_create(offer)
end
end
