The object here is "data" and you should be able to easily access this information on the client side. Next, you can limit which fields get returned from a SQL query using 'find(:all, :select => "arg1, arg2, ...", ... )'. Finally, the easiest way to convert an AR instance to JSON is to use to_json method on the instance (i.e. object.to_json). Otherwise, you can write a simply method, to_hash or to_h, which returns the hash of the AR. Then you'll have something like this: def to_hash { :name => self.name, :username => self.username, :role => self.role } end render :json => { :success => true, :data => record.to_hash } Good luck, -Conrad > render :json => > { > :success => true, > :data => record # Without to_json method > } > > The output will be: (the data attribute is an object) > {"success":true,"data":{"name":"The > > Administrator","username":"admin","role":"admin","id":1,"password":"d033e22ae348aeb5660fc2140aec35850c4da997"}} > > Instead of: (the data attribute is a string) > {"success":true,"data":"{\"name\":\"The > Administrator\",\"username\":\"admin\",\"role\":\"admin\"}"} > > The problem is, I want to hide several attributes from the output, and > the only method that I know is to use :except parameter from to_json > method. > > So, my objective is to get the output similiar to output #1, but without > the ID and password attribute. > -- > Posted via http://www.ruby-forum.com/. > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]<rubyonrails-talk%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
