Hi all, Being a beginner in Ruby on Rails, I face issues with Drag & Drop. Would you please give a simple working complete example for Drag and Drop (with 2 lists)? Or please find the below snippet and please help me find a solution. Scenario: Two draggable and droppable lists. Any item from one list should be dropped to the other. Note: Relevant code snippet is given below. Issue: While dropping, the already existing items get replaced by the dropped one. Reason would be – When the update_sel action is called, @selected is not getting fetched with the old values (say, Project.find(:all, :conditions => "id <= 4")). Solution: A solved method or an entirely new method for drag & drop will do. I prefer a new complete drag and drop method to the solved code of the same. Tip on the look and feel enhancement will also be very helpful. A prompt response would be appreciated. Code Snippet: #Controller before_filter :get_projects, :only => [:update_all, :update_sel] def update_all render :partial =>"allproj", :object => @available end def update_sel #@selected.push Project.find(:all, :conditions => "id = " + params[:id]) #This gets error - but this needed @selected = Project.find(:all, :conditions => "id = " + params[:id]) render :partial =>"selected", :object => @selected end private def get_projects @projects = Project.find(:all) @available = Project.find(:all) @selected = Project.find(:all, :conditions => "id <= 4") #For the time being - later another table used end #View #index.rhtml <div id="all_proj" style="border:1px solid;"> <%= render :partial =>"allproj", :object => @available %> </div> <br /> <h5>Selected Projects</h5> <div id="sel_proj" style="border:1px solid;"> <%= render :partial =>"selected", :object => @selected %> </div> <%= drop_receiving_element("all_proj", :accept => ''sel_item'', :url => { :action => "update_all"}, :loading => visual_effect(:highlight), :complete => visual_effect(:fade), :update => ''all_proj'') %> <%= drop_receiving_element("sel_proj", :accept => ''all_item'', :url => { :action => "update_sel"}, :with => "''id='' + encodeURIComponent(element.id)", :loading => visual_effect(:highlight), :update => ''sel_proj'') %> #_allproj.rhtml <ul> <% allproj.each do |project| %> <% domid = "#{project.id}" %> <li class="all_item" id=''<%= domid %>'' style="cursor:move;"><%=project.proj_name %> <%= draggable_element(domid, :revert => true) %> </li> <% end %> </ul> #_selected.rhtml <ul> <% selected.each do |project| %> <% domid = "#{project.id}" %> <li class="sel_item" id=''<%= domid %>'' style="cursor:move;"><%=project.proj_name %> <%= draggable_element(domid, :revert => true) %> </li> <% end %> </ul> Thanks & regards, -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
