What Does ActiveRecord::MultiparameterAssignmentErrors Mean?

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

This error can also occur with webrat/cucumber when filling in form data using a table.

eg this doesn't work:

When I fill in the following:
  | report_from_1i | 2010     |
  | report_from_2i | January  |
  | report_from_3i | 1        |
  | report_to_1i   | 2010     |
  | report_to_2i   | February |
  | report_to_3i   | 1        |

but this does:

When I fill in the following:
  | report_from_1i | 2010 |
  | report_from_2i | 1    |
  | report_from_3i | 1    |
  | report_to_1i   | 2010 |
  | report_to_2i   | 2    |
  | report_to_3i   | 1    |
