passing json parameter in ruby on rails

[amvis]

Just i called one function in my program, but i need to pass one json parameter...But getting the error like

ArgumentError (Unknown key: branch_id):

CODE

branch1(params[:branch])

def branch1(branch)

  branch123 = Branch.find(params[:branch])

end

And my rest-client body is 

{"user": {"password":"password","user_name":"user2"},"branch":{"branch_id":"1"}}

Do you mean that is the value of params? If so then params[:branch]
is a hash rather than a id value. Perhaps you mean
find(params[:branch][:branch_id]), or perhaps I misunderstand what you
are trying to do.
