Developing an application with angular I came into a problem. In my application I use cancan ( https://github.com/ryanb/cancan ). Now when showing data in a table i have to filter if the logged user can or cannot edit, view etc, and thus disabling buttons that allow given operations. When using ror its not a problem: %td -if can? :edit,script %a{:href=>edit_script_path(script)} edit but when i need to do the same thing with angular i need to mark the row data inside the controller with a flag eg. can_edit, can_view and then so i come up with an idea to add an attribute to each row before rendering to json: @scripts.each do |script| script[:can_edit]=can?(:edit,script) end
but then i get the depriciation warning: Writing arbitrary attributes on a model is deprecated. Please just use `attr_writer` An option to add columns can_edit, can_view to my table is out of the question, allso taking the cancan logic into angular is allso not an option as I think that all of the logic is allready in cancan. So for me it comes down to how can I add the attributes that are not in my tables to models? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
