Django ModelAdmin - 字段集......表单中缺少字段“日期" [英] Django ModelAdmin - fieldsets ... field 'date' missing from the form

问题描述

我在写这个问题时发现了问题所在.无论如何我都会发布它，以防它可以帮助其他人.

错误:'FooAdmin.fieldsets[0][1]['fields']' 指的是表单中缺少的字段 'date'.

The error: 'FooAdmin.fieldsets[0][1]['fields']' refers to field 'date' that is missing from the form.

使用以下代码:

# models.py
from django.db import models

class Foo(Base):
    date = models.DateField(auto_now_add=True)
    title = models.CharField(max_length=255)

# admin.py
from django.contrib import admin

class FooAdmin(BaseAdmin):
    list_display = ("title", "date")
    fieldsets = (
        (None, {
            "fields": ("date", "title")
        }),
    )

admin.site.register(Foo, FooAdmin)

推荐答案

错误是由于日期具有 auto_now_add=True(或 auto_now=True).
由于该值是自动的，因此不可编辑，因此不在表单中.要解决这个问题，请在 FooAdmin 中添加:

The error is due to date having auto_now_add=True (or auto_now=True).
As the value is automatic, it's not editable, so it's not in the form. To solve that, add this in FooAdmin:

readonly_fields = ("date",)
