I have a Post model and my controller looks like this:
class Admin::PostsController < Admin::AdminController
active_scaffold :posts do |config|
config.columns = [:title, :body, :user_id]
config.list.columns = [:title, :body, :user_id]
end
end
Each Post belongs to one User, each User has many Posts. Pretty
basic.
First Question: Using the code above, when I go to create or edit a
post, the user_id appears as an input field in the form and the poster
actually has to manually enter their user_id in order for the
association to be written to the database. How can I do this
automatically. I know how to remove the user_id field and label from
the form. Do I have to do this in my model? Like a before_create
filter or something?
Second Question: I want to allow admins to be able to change the
user_id for each post. This would best be accomplished by having a
drop-down select menu that is greyed out unless the user is an admin.
Again, I think I can figure out how to grey the select-box out for
admins, but I am having trouble getting the user_id to appear in a
select box in the first place. From reading the docs, I was under the
impression that the following code might work, but it just throws up a
noMethodError (which I would be happy to post, if anyone needs to see
it):
config.columns[:user_id].form_ui = :select
I also tried this code using "record_select" instea of just "select"
I'm a bit stuck, any help would be really great.
Thanks in advance.
