Suppose I have a model:
class SomeModel(models.Model): id = models.AutoField(primary_key=True) a = models.CharField(max_length=10) b = models.CharField(max_length=7) Currently I am using the default admin to create/edit objects of this type. How do I remove the field b from the admin so that each object cannot be created with a value, and rather will receive a default value of 0000000?

To set default form values with Django Python, we create the form instance with the default values in the constructor arguments. Or we can put the default values in the form definition. to create a JournalForm instance with the initial argument set to a dictionary with the initial form values.
@AlfonsIngomar Incorrect, from the docs - docs.djangoproject.com/en/1.8/ref/models/fields/#null "If True, Django will store empty values as NULL in the database. Default is False."
required is often used to make the field optional that is the user would no longer be required to enter the data into that field and it will still be accepted. Let's check how to user required in a field using a project.
Set editable to False and default to your default value.
http://docs.djangoproject.com/en/stable/ref/models/fields/#editable
b = models.CharField(max_length=7, default='0000000', editable=False) Also, your id field is unnecessary. Django will add it automatically.

You can set the default like this:
b = models.CharField(max_length=7,default="foobar") and then you can hide the field with your model's Admin class like this:
class SomeModelAdmin(admin.ModelAdmin): exclude = ("b") If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
