I have to sites running on port 3000 and 3001

I read the Client model via ActiveResource. Creating and deleting  
is working but updating causes the following error:

NoMethodError in ClientsController#update  
undefined method `update\_attributes’ for #Client:0x22fce78

Is ActiveResource broken?

I run Rails 2.1.0.

Thanx

To update a resource, you should be able to just change your  
attributes as desired and then call object.save(). ActiveResource  
should translate that to a PUT request, which the server app should  
then map to the update() action on the server resource.

Unless I’ve misunderstood your question…?

Ok, I just changed this:

def update  
@client = Client.find(params[:id])

```
 respond_to do |format|
   # if @client.update_attributes(params[:client])
   if 1 == 1
     @client.lastname = "BLAHBLAH"
     @client.save
     flash[:notice] = 'Client was successfully updated.'
     format.html { redirect_to(@client) }
     format.xml { head :ok }
   else
     format.html { render :action => "edit" }
     format.xml { render :xml => @client.errors, :status

```

=\> :unprocessable\_entity }  
end  
end  
end

It works! THanx. So the standard code generated by script/generate …  
is useless?
