我正在使用Django 1.11,我尝试通过引用此链接https://code.djangoproject.com/wiki/DynamicModels来创建Django动态模型,通过执行它运行的每一步而没有任何问题,但是当我在Django管理员中看到注册的模型时面板,模型在相应的应用程序下可见,但它无法访问,我不知道我错过了什么。

def create_model(name, fields=None, app_label='', module='', options=None, admin_opts=None):
    """
    Create specified model
    """
    class Meta:
        # Using type('Meta', ...) gives a dictproxy error during model creation
        pass

    if app_label:
        # app_label must be set using the Meta inner class
        setattr(Meta, 'app_label', app_label)

    # Update Meta with any options that were provided
    if options is not None:
        for key, value in options.iteritems():
            setattr(Meta, key, value)

    # Set up a dictionary to simulate declarations within a class
    attrs = {'__module__': module, 'Meta': Meta}

    # Add in any fields that were provided
    if fields:
        attrs.update(fields)

    # Create the class, which automatically triggers ModelBase processing
    model = type(name, (models.Model,), attrs)

    # Create an Admin class if admin options were provided
    if admin_opts is not None:
        class Admin(admin.ModelAdmin):
            pass
        for key, value in admin_opts:
            setattr(Admin, key, value)
        admin.site.register(model, Admin)

    return model

此处模型测试11 是通过动态模型方法创建的,我无法访问该模型,添加/更改按钮也不存在,当我杀死服务器并重新启动它,动态创建的模型被隐藏。

如何访问此型号?我错过了这里的任何步骤或者它有什么问题吗?

我遇到了同样的问题,但是几行代码解决了这个问题。您将需要注册动态模型,然后重新加载并清除缓存。它看起来像这样:

from django.contrib import admin
from django.core.urlresolvers import clear_url_caches
from django.utils.module_loading import import_module

admin.site.register(model, admin_options)
reload(import_module(settings.ROOT_URLCONF))
clear_url_caches()
