Okay, so this is really a beginner''s question. I''m just
starting to
move over from ColdFusion to Rails and I''m having some trouble
accessing ActiveRecord objects from within views.
I''m sure I''m missing something pretty obvious. I have a page
model, a
pages_controller, a content model and a content_controller. The idea
is for the content controller to manage the administrator''s
interaction with the content and for pages to display the content to
visitors.
But I''m having problems referencing the variables inside the
pages_controller. I have:
def show
@page=Page.find(params[:id])
@content = Content.find(:all)
end
I have a partial view _header.rhtml that just has:
<% for page in @pages %>
<ul>
<li><%=@page.title%></li>
</ul>
<%end%>
There are two problems: 1) It lists only the page currently being
shown (probably because of the @page=Page.find(params[:id]) line--I
need to figure out a way to list all of the pages and 2) Although I''ve
established the relationship between content and pages in their
respective model pages, I need a way of referencing only the content
associated with the page being viewed.
I know its basic, but if anyone could throw out some help, I''d
appreciate it.
Ron

If you define @pages (possibly with something like @pages = Page.find(:all)) you''ll have more luck. And as a seperate observation... you might want to just make ''content'' a text column on the pages table, and call it with @page.content, instead of making it an entire different class. -- http://www.5valleys.com/ http://www.workingwithrails.com/person/8078 --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hi Jon, Thanks! That''s helpful. I guess my thought behind making pages a separate controller is that I wanted to be able to login at some point down the road and edit the content of pages. For some reason, I got it in my head that it would be better to have a separate controller for the presentation part and another for the content part. I guess if I had just one controller, I''d just change the controller to require authorization to edit?

Depending on your implementation, you may want to do separate controllers, or maybe not. However, that wouldn''t change how you setup your models. It''s a common misconception I see with people just getting into Rails (I even had it myself once) that there is a 1 to 1 correlation to models and controllers. It''s not uncommon in complex Rails apps however to have some controllers deal with multiple models in a single action and to have several controllers that all share one model but do different things with it.
