migration fails on FieldTable with `has_total=False` #58

Closed cliftonmcintosh closed 8 years ago

cliftonmcintosh commented 8 years ago

Is there a trick to migrations for a FieldTable where has_total=False? I've tried to create a FieldTable with that setting, but with no luck.

Here is my table declaration:

FieldTable(['life expectancy'], universe='Population', table_per_level=False,
           has_total=False)

Here is the error I get:

ValueError: I couldn't work out the columns from them model.

Is there another step that needs to be taken?

I see FieldTables with the has_total=False setting in wazimap-za. However, I also can't get python manage.py migration to run for them. Here is the output.

  File "/home/cmcintosh/code/wazimap-za/wazimap_za/tables.py", line 53, in <module>
    FieldTable(['type of crime', 'year'], id='crimes_type_of_crime_year', description='Contact and property crimes by year', year='2015', has_total=False, universe='Crimes', dataset='Police Crime Statistics 2006-2015')
