cannot update attribute within users model in custom action


  • Your form is not submitting the values properly may be. So inspect your params in the binery select action.
  • record#update_attributes doesn't take a single value, it accepts hash. So the proper code should be something like:

    rails version < 4

    if @user.update_attributes(params[:user])

    in rails 4.*

    if @user.update_attributes(user_params)

in controller make sure you have permitted the user parameters.

Custom Action for Wix Installer failing after first time run
Without seeing your entire WiX file, it will be hard to tell you what is going wrong. There are many elements which may be blocking it.
