python - Django 获取表单未排序列表

Question

我在创建新对象时更改了我的管理表单以隐藏某些字段，但它按字母顺序排列字段，我想按它们在我的模型中的顺序排列它们。有什么建议吗？

_add_fields = ('name', 'size', 'slug',
               'img', 'description', 'quantity')

def get_form(self, request, obj=None, **kwargs):
    model_form = super(ItemAdmin, self).get_form(
        request, obj, **kwargs
    )

    if obj is None:
        model_form._meta.fields = self._add_fields
        model_form.base_fields = {
            field: model_form.base_fields[field]
            for field in self._add_fields
        }

    return model_form

Answer 1

您需要使用 collections 模块中的 OrderedDict 来实现:

from django.contrib import admin
from collections import OrderedDict


class ItemAdmin(admin.ModelAdmin):

    _add_fields = ('name', 'category',
                   'img', 'description', 'quantity')

    def get_form(self, request, obj=None, **kwargs):
        model_form = super(ItemAdmin, self).get_form(
            request, obj, **kwargs
        )

        if obj is None:
            model_form._meta.fields = self._add_fields
            d = OrderedDict()
            for field in self._add_fields:
                d[field] = model_form.base_fields[field]
            model_form.base_fields = d
        return model_form
