Question

Not sure what’s going on. I’ve used the following bit of code to try and edit the name of a category, but I’m getting the error message above. My code for the form and submit for the edit is: –

<% form_for :category, :url => categories_url(@category),:html => { :method => :put } do |f| -%>
<p>Name: <br /><%= f.text_field :name, :size => 60 %></p>
<%= submit_tag 'Save' %> or <%= link_to 'cancel', admin_categories_url%>

So pretty straight forward stuff. My controller code is: –
def edit
@category = Category.find(params[:id])
end

# PUT /categories/1
# PUT /categories/1.xml
def update
@category = Category.find(params[:id])
@category.update_attributes(params[:category])

respond_to do |wants|
  wants.html { redirect_to admin_categories_url }
  wants.xml  { render :xml => @category.to_xm }
end  

end

This code has worked for other things – such as blog articles, so I’m not sure where I{“m going wrong. Help??

Answer 1

I think you want :url => category_url(@category) (non-plural).
