Django3:如何在HTML template和/或Admin中显示模型函数的结果

# models.py
from django.db import models

class MyModel(models.Model):
    name = models.CharField(max_length=100)

    def my_function(self):
        # 这里可以执行一些逻辑并返回结果
        return f"Hello, {self.name}!"

# views.py
from django.shortcuts import render
from .models import MyModel

def my_view(request):
    instance = MyModel.objects.get(pk=1)  # 获取模型实例
    return render(request, 'my_template.html', {'instance': instance})

<!-- my_template.html -->
<p>{{ instance.my_function }}</p>

# admin.py
from django.contrib import admin
from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    list_display = ('name', 'my_function')  # 添加'my_function'到显示列表

admin.site.register(MyModel, MyModelAdmin)

# models.py
class MyModel(models.Model):
    name = models.CharField(max_length=100)

    def my_function(self):
        return f"Hello, {self.name}!"

    # 专用于Admin的方法
    def display_my_function(self):
        return self.my_function()
    display_my_function.short_description = 'Custom Function Result'  # 设置列标题

# admin.py
class MyModelAdmin(admin.ModelAdmin):
    list_display = ('name', 'display_my_function')
