In update date i get all updated value while i checked it with debugger but its not save in database. I found one reason is "add_taxes" method which successfully called in create but not called in update operation. Also remember my "taxes" variable is serialize and i used accepted_nested_attributes _for.</p> <p>Can anyone please help me. </p>
