ruby on rails - How to change values overriding the 'to_json' method? -

-

i using ruby on rails 3 , override to_json method.

at time use following code in order avoid export important information.

  def to_json     super(       :except => [         :password       ]     )   end

if want change value using method, how can do?

for example, capitalize user name

:name => name.capitalize

on retrieving this

@user.to_json

if want render :json => @user in controller rails 3, can override as_json in model: 

class user < activerecord::base   def as_json(options={})     result = super({ :except => :password }.merge(options))     result["user"]["name"] = name.capitalize     result   end end

here's post differences between to_json , as_json.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.
