Frustrated with rails has_many problem

Ruby
1

hello there all,

i am writing a website in rails, i love it, but i am banging my head
here .

ok, i have a table called sites ( means customer sites )
each site has_many :site_notes
so, site_note belongs_to :site

i used a scaffold to generate the site notes files. site notes work
kinda
like comments to a blog.
a customer has sites and for each site, i want him to be able to post
notes
about what what his machines are doing.

so, my link to the sites controller looks like this.
<%= link_to “site notes”, :action => “list”,
:id => @site,
:controller => ‘site_notes’ %>

and in the site_notes_controller.rb i have this
def list
@site = Site.find(params[:id])
@site_notes = SiteNote.find(:all, :conditions => [“site_id”,
@site.id])
@site_note_pages, @site_notes = paginate :site_notes, :per_page =>
10
end

everything seems to work, it lists the right notes, i can edit and
delete
them etc…
but when i try to add a new one, it tells me that it cannot find a Site
without an id.
so, i guess i need to know how to put something either in the model or
controller, (or view, whatever works)
that will automatically add site_id = @site.id when i create a new note

thanks

You need to do that by hand, sorry.

so, in my situation, would i need to keep passing the Site.id (or, for
the
site_notes table, site_id) as a variable from action to action in the
controller?

thanks

you can do this:

<%= link_to “site notes”, :action => “list”,
:id => @site.id, # here will using @site.id
:controller => ‘site_notes’ %>

and in the site_notes_controller.rb i have this

def list
@site = Site.find(params[:id])
@site_notes = @site.site_notes # if you use has_many association you
can
just write this
@site_note_pages, @site_notes = paginate :site_notes, :per_page => 10
end

thanks, that helped a lot, i am able to move around the controller
passing

@site to each next action, and putting it in the form as a hidden field.
Thanks for the tip there
