Question

I have a code like this:

User.create(params[:user])

But if someone sends params through API like

{"userr":{"name":"Firstname"}}

then I get 500 error because of undefined method * for nil:NilClass. How should I handle this and should I at all?

Answer 1

Of course you should handle false input – this is a situation which might happen in production as well.

I’d simply do:

if params[:user].blank?
  # Handle false input here
else
  User.create(params[:user])
end
