bypass attr_accessible/protected in rails -

-

I have a model, when instantiates an object, then creates another object from the same user id. 

  Square Fu & gt; ActiveRecord :: Base after_create: create_bar Personal Def create_bar Bar.create (: user_id = & gt; user_id # and other attributes) In the end end

in Bar.rb to protect me from hackers Attr_protected. 

  class bar> ActiveRecord :: Base attr_protected: user_id, created_at ,: updated_at end

Now it stands as I appear to disable attr_protected or to create a new bar object without having bar object Can not User_id be empty ...

How do I accept bar objects: atti_protected without losing security from foo to user_id attribute? Try

: 

  def create bar = bar Build (... other parameters ...) bar.user_id = user_id bar.save! End

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
