Python 使用 wsgi.py 和 apache2 的 Django 每次重新启动时都会乱序加载过滤器字段

Question

我有一个 Django 应用程序，当运行 python manage.py 在本地运行服务器命令时，它工作正常。当我尝试迁移它并修改我的 apache 配置文件以使用 wsgi.py 时，除了 Django 过滤器字段在 Django table 之上的一页之外，一切正常。每次我重新启动 apache 服务器时，过滤器字段都会以新的顺序重新洗牌。本地服务器总是以正确的顺序显示过滤器字段。有谁知道为什么会这样？

本地服务器使用 python runserver 命令

使用 wsgi 的 apache 服务器

apache2.conf

    WSGIDaemonProcess /SeedInv python-home=/path/to/Software/anaconda3/envs/Django python-path=/path/to/WebServer/SeedInv

                                )

    def __str__(self):
        return self.genotype

    class Meta:
        verbose_name_plural = "Genotypes"

感谢您的帮助！

，你不应该依赖被订购的字典。如果键的顺序很重要，您可以使用 OrderedDict。

from collections import OrderedDict

class GenoFilter(django_filters.FilterSet):

    class Meta:
        model = Genotypes
        fields = OrderedDict([
            ('parent_f_row', ['icontains']),
            ('parent_m_row', ['icontains']),
            ('parent_f_geno', ['icontains']),
            ('parent_m_geno', ['icontains']),
            ('genotype', ['icontains']),
            ('seed_count', ['lt', 'gt']),
        ])

Python 使用 wsgi.py 和 apache2 的 Django 每次重新启动时都会乱序加载过滤器字段

Python Django using wsgi.py with apache2 loads filter fields out of order every restart

python

apache
