The "show" for a row from feeds works correctly, showing both rows
which that feed row. However, I''d like to add a "add" button
(and a
"remove"?) to the "Editing feed" page so that the the rows
from
categories will be associated/unassociated with that feeds row.
(There''s a many-to-many relationship between "feeds" and
"categories".)
Feed: feed1
Edit | Back
Itemized Categories
cat1
category2
<http://localhost:3000/feeds/show/1>
Feed: feed2
Edit | Back
<http://localhost:3000/feeds/show/2>
Editing feed
Feed
Category
Show | Back
<http://localhost:3000/feeds/edit/1>
