Rails控制器没有创建新记录

Question

I have a definition

def create
   @person = Person.new(params.require(:firstname, :lastname, :job).permit(loc))
   @person.save
   redirect_to @person

When I try to save a new person I get the following error:

ArgumentError in PeopleController#create
wrong number of arguments (5 for 1)

Is there an issue with the way I coded it? I also tried separating out each element with a separate ".require".

Answer 1

Typically you want something like params.require(:person).permit(:firstname, :lastname, :job, :loc) then have your Person model validate the required attributes.

As for your issue, my guess is if you check your params you will see something like {person: {firstname: "first", lastname: "last", job: 1, loc: "somewhere"}} coming through and that is why your Person.new is raising that error.
