Only show content when certain criteria is met?
- by Elliot
I'm wondering if theres a best practice for what I'm trying to accomplish...
First we have the model categories, categories, has_many posts.
Now lets say, users add posts.
Now, I have a page, that I want to display only the current user's posts by category.
Lets say we have the following categories: A, B, and C
User 1, has posted in Categories A and B.
In my view I have something like:
@categories.each do |category|
category.name
@posts.each do |post|
if post.category_id==category.id
post content here
end
end
end
The problem with this, is I'm going to show the empty category, as well as the categories that do have content.
Is there a more efficient way of going about this? As I don't want to show the empty categories.
Best,
Elliot
