Problem with ForeignKeyWidget

I’m following the docs on ForeignKeyWidget very closely, and am still getting an error when uploading an Excel file. My resource looks like this:

class AssignmentResource(resources.ModelResource):
	instruction_type = fields.Field(
		column_name='instruction_type',
		attribute='instruction_type',
		widget=ForeignKeyWidget(InstructionType, 'type')
	)

	class Meta:
		model = Assignment
		fields = ('instruction_type',)

type is a string field on the InstructionType model. When I try to upload a spreadsheet that has string values, I get this error:

Line number: 1 - Column 'instruction_type': invalid literal for int() with base 10: 'Research'

What am I doing wrong?

So… I never actually added the line resource_class = AssignmentResource to my AssignmentAdmin class.

Sorry for the runaround!

I told myself I couldn’t possibly have forgotten this and lo and behold I checked and…I also forgot to do this. THANK YOU!
