Re: It is impossible to add a non-nullable field 'details1' to feature without specifying a default. This is because the database needs something to populate existing rows.

2023-03-27 Thread Erik Manuel Herazo Jimenez 
hello, you must apply the default=None, or default="" feature, so that
those fields can be filled.
ex:
details1 = models.CharField(max_length=500, default="")

Re: It is impossible to add a non-nullable field 'details1' to feature without specifying a default. This is because the database needs something to populate existing rows.

2023-03-26 Thread Sandip Bhattacharya 
So what would you want for existing entries in the table which were added 
before you changed the model?

If you are ok with them being empty, you should use:
details = models.CharField(max_length=500, default=“”)

And run migrate again.

If you are ok instead of this column being null, then:
details = models.CharField(max_length=500, null=True, blank=True)

I don’t have a huge experience with migrations, so others can correct me if I 
am wrong, but intuitively I feel that defaults should be captured in code than 
doing one-off fixes manually while running migrations at the command line.

Thanks,
  Sandip

2023-03-25 Thread Henock Lungele 
That means you have done some changes in your model python file. So you
have to drop your data base, delete the migration files, recreate the
database with the same name as in your configuration python file and do
migrations again. This will work or you can add default parameter with a
value after max_length parameter for example default="" this will work too
but if you take a look to your sql codes, you have define a default
behavior if the user type nothing in the input field.
I'm sorry, i speak a little bit english i'm from a french country.

Thats because you have values in the database...
If you don't need the data... eliminate the 001, 002, etc files of the
migration folder...(this folder is in each application folder) and
applicate the migrations again.

You are seen that error probably because you modified your models after
