Extjs on rails - return value


#1

working on extjs on rails for tree structure
when creating a node, no value should be returned to the json
its giving an alert of the return value

def additem
@return_val = Tree.new(:parent_id=>params[:parentID],:node_name=>‘New
Folder’)
@return_val.save
return_data = ‘’
render :text=>return_data.to_json, :layout=>false
end

can anyone help to figure out the problem please!!

Thanks in advance!!
