CodePudding user response：

Are you doing search system? If you do, so use get_queryset(self). That will return username, that you search. And get_context_data()

 def get_queryset(self):
    return User.objects.filter(username__icontains=self.request.GET.get("q"))

def get_context_data(self, *args, **kwargs):
    context = super().get_context_data(*args, **kwargs)
    context["q"] = f'q={self.request.GET.get("q")}&'
    return context

Write down this one into your view, where is your search app. in template, search form must have name='q'

Assume you have a model named class Department(models.Model) with 2 fields (name, description) in models.py like this:

from django.db import models

class Department(models.Model):
    DEPT_NAME = (
        ('Staff', 'Staff'),
        ('Manager', 'Manager'),
    )
    name = models.CharField(max_length=15, choices=DEPT_NAME)
    description = models.CharField(max_length=100, null=True, blank=True)

    def __str__(self):
        return self.name

At Django admin page you only want search result of name field.

In your admin.py, use the search_fields attribute of the ModelAdmin:

from django.contrib import admin
from .models import *

@admin.register(Department)
class DepartmentAdmin(admin.ModelAdmin):
    DEPT_NAME = (
        ('Staff', 'Staff'),
        ('Manager', 'Manager'),
    )
    name = models.CharField(max_length=15, choices=DEPT_NAME)
    description = models.CharField(max_length=100, null=True, blank=True)
    search_fields = ('id', 'name',) # <-- Choose any field you want Django search
