Form_remote_tag and form parameters problem in edge


#1

Hi guys,

anybody encountered such a problem that <% form_remote_tag … %>
doesn’t send the data present in the form on submit?

Let me explain:

I have Products and the products have Properties.

routes.rb

map.resources :products do |product|
product.resources :properties
end

I have a product edit form, which lists all the properties currently
assigned to the product row by row, simple.

_properties.rb

<% @product.properties.each do |property| %>



<% form_remote_tag( :url => property_path( @product,
property ), :method => :put ) do %>


<%= submit_tag “Save” %>
<% end %>


<% end %>

The property controller takes care of updating:

properties_controller.rb

def update
return false unless request.xhr?
@property = ProductProperty.find( params[:id] )

debug

logger.info “PARAMS: #{params.inspect}”

@property.update_attributes( params[:property] )
@product = Product.find( params[:product_id] )
end

All fine and dandy, there are 3 properties listed, I changed the
values in the form and click save next to it. Log says:

development.log

ProductProperty Columns (0.007000) SHOW FIELDS FROM
product_properties
ProductProperty Load (0.002000) SELECT * FROM product_properties
WHERE (product_properties.id = 18)
PARAMS: {“action”=>“update”, “product_id”=>“1”, “id”=>“18”,
“controller”=>“properties”}

NoMethodError (You have a nil object when you didn’t expect it!)

Of course nil, because params[:property] is nil and i’m trying to
udpate_properties( ) on it. Log says, no additional parameters passed
along with the request, but which were present in the form_remote_tag
declaration.

Some additional info: same situation, plain <% form_tag … %> works
like a charm. Seems like a bug in <% form_remote_tag … %>.

Am I missing something? Tried everything at my disposal, still no
luck. I’m on edge rails, latest revision.

Thanks and my best regards,
András

I think the problem you’re having is probably related to the fact that
you’re hardcoding the form elements rather than letting Rails know about
them. Try switching to text_field or text_field_tag and see if that
doesn’t
help.
