ruby on rails - How to restrict user access page in RoR? -

-

I know that after the user login I can have a session and at the same time, I have an assistant method called "Current_User" I have not created any other people who can not get signed access to the page. How can I do this by doing this?

I can do that people are not allowed to gain access to the content, but I do not want to see the user blank pages within the login itself. 

  & lt;% if current_user% & gt; My content & lt;% end% & gt;

Make the first_filter, which checks that the current_user variable is set, and redirects the user Does some other place (root, signup page, something) if it is not. Something like this: 

  class ApplicationController & lt; ActionController :: Base DF login_require redirect_to ('/') if current_user.blank? End and class microcontroller & lt; ApplicationController before_filter: login_required ,: only = & gt; : Action_aviable_only_for_logged_in def action_aviable_only_for_logged_in ... and 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...
