Q: master/child where children are added with ajax

Rails
1

Say my user creates an Article and an Article has_many :links. The edit
form
for article contains an “add link” link_to_remote that brings up an edit
line for links for further reading. The problem is that there is that
the
Article is not yet saved, so it’s unclear how to accumulate or remove
these
items.

I’m sure others have implemented similar things. Hints?

Thanks

Save the parent before using it then you have the ID. If the users
cancels, destroy it

So you’re advocating:

link_to_remote ‘new child’, :url => {:action => ‘do_something’}

def do_something
save_master_record
fall_through_to_rjs_add_child_records
end

BTW: Sorry about the numerous posts of the same question. Nabble hung
and I
didn’t know whether the post got through. Maybe email is better :slight_smile:
