Question

In my controller i have two actions: "Select_users" and "Make_something".
In “Select_users” i get a @var with a list of users (this users are generated from a search with a form in the same view) and i need to make an insert for each of those … like:

   @var.each do |v|
     Table.create(:atribute => v.name)
   end

When i have my list of selected users i use a Submit button to send me to the “Make_something” action.

So i was thinking to “pass” the @var variable to the “Make_something” action to make this create, but I can’t use @var in “Make_something” because it’s accesible only in “Select_users”.

I read about filters but i think they cant help me with this problem.

Thanks!

If you have code common to several methods, extract it out to another method.

def select_users
  @var = go_get_those_users
end

def make_something
  go_get_those_users.each do |v| Table.create(:atribute => v.name) end
end

private
def go_get_those_users
  # do whatever you need to populate your collection
  return [] 
end

Alternatively, you could pass the list of IDs of the selected users in the form that posts to “make_something”. Or if you really want to persist this somehow (I assume this is some form of “multi-step form wizard” of some description), user the db, not the session – have a “wizard” model that is retained in the DB. Each step would then pass the wizard_id, and save its own values to the wizard – this could have normal AR associations (for your selected users) through relationships.
