yes, i think i'm following exactly the tutorial, however it doesn't
work...
here's the code:
#profile model:
class Profile < ActiveRecord::Base
belongs_to :company
has_and_belongs_to_many :services
[...]
end
#
#service model:
class Service < ActiveRecord::Base
has_and_belongs_to_many :profiles
validates_presence_of :name
end
#
#profile_controller
def update
params[:profile][:service_ids] ||= []
@profile = Profile.find(params[:id])
@total_services = Service.find(:all, :order => 'name')
@profile.update_attributes(params[:profile])
@company = @profile.company
redirect_to :action => 'show', :id => @company.id
end
#
#partial that displays the services (i'm calling @total_services from
the show controller)
<table>
<% for s in @total_services -%>
<tr>
<td></td>
<td>
<%= check_box_tag "profile[service_ids][]", s.id,
@profile.services.include?(s) %>
<%= s.name -%>
</td>
</tr>
<% end %>
</table>
#
#
I've checked the generated log, and it creates the insert query when i
have newly checked services in my view, but it doesn't create the
delete query when i do uncheck.
