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”}}

{"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.

Hi,

Get the data of

branch=params[:branch] [:branch_id] unless params[:branch].nil?

send this branch to the method.
