This is a crappy example of how to use https://github.com/ledermann/rails-settings in a form. The setting get turned into a hierarchy of SetttingsObjects and then are used to set the form values. The settings will come back as "project"=>{ "settings"=>{"colors"=>{"edge"=>"red", "fill"=>"blue"}}} from the form and are proccessed in the controller code. strong_parameters is completely ignored. This is probably a bad thing that could be fix |
