What Does ActiveRecord::MultiparameterAssignmentErrors Mean?

Question

I have a rails form with a datetime_select field. When I try to submit the form, I get the following exception:

ActiveRecord::MultiparameterAssignmentErrors          


        

Answer 1

ActiveRecord throws the MultiparameterAssignmentErrors exception when you try to set an invalid date to a models attribute.

Try to pick a Nov 31 date from the date_select or datetime_select dropdown and you will get this error.
