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
