[Django]-Can you change a field label in the Django Admin application?

If your field is a property (a method) then you should use short_description:

class Person(models.Model):
    ...

    def address_report(self, instance):
        ...
    # short_description functions like a model field's verbose_name
    address_report.short_description = "Address"

As Javier suggested you can use verbose name in your fields in model.py. Example as below,

class Employee(models.Model):
     name = models.CharField(max_length = 100)
     dob = models.DateField('Date Of Birth')
     doj = models.DateField(verbose_name='Date Of Joining')
     mobile=models.IntegerField(max_length = 12)
     email = models.EmailField(max_length=50)
     bill = models.BooleanField(db_index=True,default=False)
     proj = models.ForeignKey(Project, verbose_name='Project')

Here the dob,doj and proj files will display its name in admin form as per the verbose_name mentioned to those fields.

If you want change the field label only on particular admin model without changing field of the model:

class MyModelAdmin(admin.ModelAdmin):    
    def get_form(self, request, obj=None, **kwargs):
        form = super().get_form(request, obj, **kwargs)
        form.base_fields["name"].label = "New label"
        return form

from django.db import models

class MyClassName(models.Model):    
    field_name = models.IntegerField(verbose_name='Field Caption')

Building on Javier’s answer; if you need one label in forms (on the front-end) and another label on admin it is best to set internal (admin) one in the model and overwrite it on forms. Admin will of course use the label in the model field automatically.

As far as the changelist view is concerned, this can be done with a simple field function.

class MyModelAdmin(admin.ModelAdmin): 

    list_display = (
        '_name',
        ...,
    )

    @admin.display(description='Customized field name here')
    def _name(self, obj):
        return obj.name

You can use verbose_name to change a field label in Django Admin as shown below.

# "models.py"

class MyModel(models.Model):                # Here
    name = models.CharField(max_length=255, verbose_name="My name")

In addition, you can put a field label to the 1st argument without verbose_name as shown below:

# "models.py"

class MyModel(models.Model):
    name = models.CharField("My name", max_length=255)
                            # Here
