Here’s a situation:
A product belongs to multiple categories and the categories are top
menus of a site.
I want to highlight the category of a product when the product detail
page is loaded.
If there’s some context, I can determine which category should be
highlighted.
(For example, I can track the categories that a user selected).
But sometimes there’s no context (for example, the user visits the page
directly without getting through categories).
How can you solve this problem?

That does not make sense, do you mean product has_many categories, or
more likely category has_many products and product belongs_to
category.

If you have a product, @product say, then the the category of the
product is @product.category, assuming you have setup the ActiveRecord
relationships correctly.

Sorry.
I was not clear about this.
Product and Category are m:n relationship.
Actually there’s a Categoryship model.

It would be easier if you could just supply the relationships. I
think you are saying category has_many products through categoryship
and product has_many categories through categoryship also. In that
case if you have a product then the categories are available as @product.categories. I am not sure what your question is.
The problem is that @product.categories is multiple.
I need to highlight only 1 category for the product and show only 1
breadcrumb.
If there’s some path that the user took, I can select the category but
if there’s no such context, I don’t know what to do.
I can make my own policy but I want to know how other developers are
doing.
So instead of products > category > product
you could do products > { multiple categories } > product
where the { multiple categories } is a mouseover dropdown to show
the list of relevant category links.
Yes, that will do.
Our top menus are categories.
I need to highlight the category.
Do you have any good idea for that?
