Thanks for responding Shawn, I am using south, and have tried using a schemamigration --auto on the database... I get the error:
? The field 'Photo_Log.sample_id' does not have a default specified, yet is NOT NULL. ? Since you are removing this field, you MUST specify a default ? value to use for existing rows. Would you like to: ? 1. Quit now, and add a default to the field in models.py ? 2. Specify a one-off value to use for existing columns now ? 3. Disable the backwards migration by raising an exception. I tried 2 things without success, and continued to get this same error message. 1. With the postgresql table defining the sample_id as NOT NULL, I set the default=0 in the model definition for this foreign key e.g. sample = models.ForeignKey(Sample, verbose_name='Sample Name', default=0). 2. Removed the postgresql NOT NULL constraint on the column sample_id and set the model definition to: e.g. sample = models.ForeignKey(Sample, verbose_name='Sample Name'). I get the same error regardless?? On May 18, 12:55 pm, Shawn Milochik <sh...@milochik.com> wrote: > You have three choices. > > 1. Use South. #1 recommendation by me.http://south.aeracode.org/ > > 2.
