why don't you learn directly from a tutor?

Greetings. Saying just a portfolio site, basically there will no Django book that will teach u that. U have to get a tutor and start from a base. I do offer some Django courses from beginner level to advanced

RE: DJANGO MODELS

i have created an application called expense in django which has two fields in the models.py file which looks like class Transactions(models.Model):

    income = models.IntegerField(null=False, blank=False)
    expense = models.IntegerField(null=False, blank=False)

I want my application to allow users to enter their expense and income themselves and these fields must be provided, it should not be empty. But when i run the command python manage.py makemigrations i get the this: It is impossible to add a non-nullable field 'expense' to transactions 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: Please select a valid option: Please select a valid option:

i have chosen option 2 but still got the same prompt. how do solve this.

You are getting this because the database needs to have a value for existing row(s), you can set default value or make the new field nullable

Either of these would work for you

Transactions(models.Model):

    income = models.IntegerField(null=True, blank=True)
    expense = models.IntegerField(null=True, blank=True)

Or

Transactions(models.Model):

    income = models.IntegerField(default=0)
    expense = models.IntegerField(default=0)
