Model update/create not saved to params[]


#1

I’m trying to build a form to create or update a model using remote
call. When I submit the form, I see that the changes aren’t applied. I
started the server with --debugger and noticed the params hash doesn’t
receive the updates. My code for update form is this:

/app/views/vendors/_vendor.html.erb

This is in the partial b/c there’s also an option to render a

read only view as a table row with vendor_nnn as its id

<% if edit_mode -%> <% form_for @vendor, :vendor, { :action => 'update', :id => @vendor } do |f| -%> <%= f.text_field :name %> <%= f.text_field :location %> <%= link_to_remote 'save', :url => { :action => 'update', :id => @vendor } %> <% end -%> <% end -%>

vendors_controller.rb

def update
@vendor = Vendor.find(params[:id])
if @vendor.update_attributes(params[:vendor])
flash[:notice] = “Vendor #{@vendor.name} was successfully
updated.”
respond_to do |format|
format.html { redirect_to vendors_path }
format.js
end
end
end

update.js.rjs – this is just to

id = params[:id]

this puts

page.replace “vendor_#{id}”,
:partial => ‘vendor’,
:object => Vendor.find(id),
:locals => { :edit_mode => false }

page.replace_html ‘flasher’, params[:vendor] unless
params[:vendor].blank?
page.remove “active_vendor”

When submitting the form it just renders the previous data, without the
changes.

You will want to use remote_form_for instead of form_for.

A bit of unasked-for advice:

Write your tests or specs and run them all the time. Make sure
everything works without the ajax. Tail your logs and watch the
actions invoked and parameters passed.

Hope this helps.
