Backbone model save

问题

I'm using rails and learning Backbone.

Help me please. Is there any way to set right model on save? When I create, for example, new user with some params and trying save it into the database, - on server side I have not user as object, but user fields in params. And only way to save user - is to set properties manually:

user = User.new(:login => params[:login], :password => params[:password]).save!

Is there any way which will generate real user model object (like a form_for generates)? I think actions described below I will need to use when I will update user and so on.

Thanks!

回答1:

There is a paramRoot 'parameter'. You say rails - so I'll assume coffee script:

class User extends Backbone.Model
  paramRoot: 'user'
<url or some other stuff>

回答2:

The 'paramRoot' parameter is used by the backbone_rails_sync adapter that backbone-rails gem provides. That's why you can't find it in backbone's website.

Another way, if you are not using the gem and it's adapter, is to render the user with :root => false

render json: @user, root: false
