ruby on rails - Rendering Partial with specific :category_id -

-

i created categories scaffold. user's can upload image , add category it. categories created in scaffold shown in dropdown users select.

on image show page link category ->

<%= link_to @pin.category.name, @pin.category%>

it takes me (for example)

localhost:3000/categories/1

on category show page want display images share same category.

how do ?

in models define catagory

has_many :images

and image

belongs_to :category

  • image should have category_id member of course

then , when have category object in hand (let's @cat), iterate @cat.images

you can read more models , relation in here
