Does using @object,name also work (not @bject which you have written above)?

Actually the variable name is not @Object. Its some thing else.  Have checked spelling, copied and pasted it. But nope. It won't work.

What do you mean it will not fetch the relation?  What is the error message?

 

There shows no error, it just returns nil object. If I give @obj.friends.first.name , it would say undefined method first for nil object!

Then @object is nil.  Perhaps you should be using @bject.

Note that when posting code it is better to copy/paste then there will
be no confusion about what the code actually is.

Yup copied, pasted and banged my head on desk a 1000 times.

Say if in the action if I keep @object2 = Person.find params[:id] and if I use @object2 in code, it works perfectly everywhere. This bug is repeatable on server and my local system running ruby 2.1.0 and Rails 4.3.

Some how rails is forgetting what @object is in the middle of view.

I'm going to assume the "3" in "4.3" is a typo - otherwise, say hi to the future people for me. :)

Anyways, the usual cause of weird name-specific behavior is that you've picked a name which is used internally by part of Rails. Sanitizing your example to "@object" rather than the real name is going to make this difficult to troubleshoot...
