Can I make an admin field not required in Django without creating a form?
PythonDjangoDjango ModelsDjango AdminDjango FormsPython Problem Overview
Every time I enter in a new player in the Admin portion of Django I get an error message that says "This field is required.".
Is there a way to make a field not required without having to create a custom form? Can I do this within models.py or admin.py?
Here's what my class in models.py looks like.
class PlayerStat(models.Model):
player = models.ForeignKey(Player)
rushing_attempts = models.CharField(
max_length = 100,
verbose_name = "Rushing Attempts"
)
rushing_yards = models.CharField(
max_length = 100,
verbose_name = "Rushing Yards"
)
rushing_touchdowns = models.CharField(
max_length = 100,
verbose_name = "Rushing Touchdowns"
)
passing_attempts = models.CharField(
max_length = 100,
verbose_name = "Passing Attempts"
)
Thanks

Solution 1 - Python
Just Put
blank=True
in your model i.e.:
rushing_attempts = models.CharField(
max_length = 100,
verbose_name = "Rushing Attempts",
blank=True
)
Solution 2 - Python
Use blank=True, null=True
class PlayerStat(models.Model):
player = models.ForeignKey(Player)
rushing_attempts = models.CharField(
max_length = 100,
verbose_name = "Rushing Attempts",
blank=True,
null=True
)
rushing_yards = models.CharField(
max_length = 100,
verbose_name = "Rushing Yards",
blank=True,
null=True
)
rushing_touchdowns = models.CharField(
max_length = 100,
verbose_name = "Rushing Touchdowns",
blank=True,
null=True
)
passing_attempts = models.CharField(
max_length = 100,
verbose_name = "Passing Attempts",
blank=True,
null=True
)

If the field is set blankable in model level, it really means empty string are allowed. An empty string and a null really aren't the same thing. Don't break your data integrity only because the framework has set some bad default features.
Instead of setting the blank, override the get_form -method:
def get_form(self, request, obj=None, **kwargs):
form = super().get_form(request, obj, **kwargs)
form.base_fields["rushing_attempts"].required = False
