Hey all,
I keep getting the following error:
You have a nil object when you didn't expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.size
Based on the current user, when they navigate to a page, I want to limit
them to what they can see based on their site. Problem is there is no
association between site and user table directly. A contact has_one user
(user information is stored in current_user variable). A site has_many
contacts. And a site has_many students, where students table has a foreign
key of site_id. So there is a link between students and site, so when the
current user navigates to students page, they can only see students from
same site as them. I can do this by hard coding a number in a named_scope to
only display students for the site of the current_user. But different users
will belong to different sites so when logged in, the site their associated
with will change. That's the problem - to dynamically set that value in a
named_scope. This is what I have:
StudentsController
def index_scoper
if current_user.role_id == 8
super.site_staff_limit while current_user[:site_id] #The problem is the
user table has no site_id. There is no direct link between the users table
and sites table. However, there is a link between users and contacts and
then site and contacts and then site and students, where students table has
site_id.
else
super.with_state.with_site
end
end
Student Model
named_scope :site_staff_limit, lambda {|site_id| {:conditions =>
{:site_id => site_id}}}
Thanks for any suggestions.
