I have some problems with doing some kind of “my own controller” in
Ruby when returning a complete class.
Let’s say we start with the following:
I have a …
- … model called Asset which has several attributes and methods.
- … model called Picture which inherits from Asset (class Picture <
- … model called Video which inherits from Asset
So far so good. In a gallery controller, I know trough a parameter for
which kind of assets a user wants to search (videos, pictures, …).
Now I had the following idea, which is not working for me and clearly
has some misunderstanding of OO.
I created a class called Media which looks like this (pseudo-code):
In my gallery-controller, I have a before-filter similar to:
params[:media] = picture
@media = Media.new(params[:media])
Later, I expect to do something like:
The important thing is, that I only want to see pictures!
I see that it is not possible to return a complete class definition.
Even returning a “Picture.new” doesn’t give me my methods defined in
the Picture model. I also don’t expect to see @media.find(:all)
working, if @media was created with a Picture.new.
Does anybody has hints in which direction to look or how to solve this
Thanks in advance!
