如何在django models.py中编写一个使用定义的函数？

from .utils import your_custom_function

class YourModel(models.Model):
    your_field = models.CharField(max_length=100)

class YourModel(models.Model):
    your_field = models.CharField(max_length=100)

    @property
    def your_custom_function_result(self):
        return your_custom_function(self.your_field)

from django.contrib import admin

class YourModelAdmin(admin.ModelAdmin):
    readonly_fields = ('your_custom_function_result',)

admin.site.register(YourModel, YourModelAdmin)
