It seems as though the default in Django when creating tables is to place a constraint that doesn't allow null values (contrary to what I've learned is the default for SQL in general). I have a model which has a date attribute, and which I now want to be able to hold null values, but when I tried doing this by adding 'null = True' and 'blank = True' to the model's field options, Django generates a
model.date may not be NULL error when I try to leave the field blank in the Django admin interface. This suggests I need to change something about the database, rather than the model, correct? If so, what is the SQL syntax for doing this? My research online has only turned up how to apply a "not-null" constraint on a database table when creating the table, not how to remove a "not-null" constraint on a table after it's been created. Thanks in advance for any help on this! -- You received this message because you are subscribed to the Google Groups "Django users" group. To post to this group, send email to [email protected].
