makemigrations

[shiva singh]

Hello I am new in Django users group. I am using Django and faching a problem when i do any changes in existing models after run  makemigrations.

This is problem :-It is impossible to add a non-nullable field 'logo' to jobdetails without specifying a default. This is because the database needs something to populate existing rows.

Please select a fix:
 1) Provide a one-off default now (will be set on all existing rows with a null value for this column)
 2) Quit and manually define a default value in models.py.

Select an option: 2

please help how can i solve this problem .

Thank you

Django can't add a new field by itself without null values being allowed here, especially when you have unique=True set on this field. To solve that issue, you have to perform it in steps:

1. Add a column with null=True or without unique=True and with some default value
2. Make sure that all records in database will have a unique value.
3. Change the field to the final state.
