Python Django 1.8操作错误：没有这样的表

我发现了很多类似的问题/答案，建议使用“迁移”和“makemigrations”，但这不起作用。我使用Python2.7和pycharm 4.5.4作为IDE。 当我为product imagefield创建了一个新模型，注册到admin，然后运行“makemigrations”，然后运行“migrate”，然后在/admin/products/productimage上出现了这个错误/ 没有这样的表：products\u productimage。我错过了什么？下面是

model.py 管理员 makemigrations和migrate的输出

在浏览器上，我看到下面的错误如果您不在乎丢失数据，可以删除SQLite3文件，然后再次运行“makemigrations”和“migrate”命令。您可能还必须重新创建一个超级用户（python manage.py createsuperuser）

您是否尝试过

migrate zero--fake

然后再次

migrate

？这对我有效，我也有同样的问题。

你能在运行这些命令时显示它们的输出吗？@ThomasOrozco我已经更新了帖子。欢呼声可能不相关，但您是指

def product\u saved\u receiver…

和

post\u save.connect…

进一步缩进一级吗？只是确认一下：明确指定应用程序时是否创建了任何迁移

makemigrations产品

@mfcovington我认为缩进是正确的。我使用django admin上传图像时遇到了这个错误。我删除了“db.sqlite3”，还删除了应用程序名->迁移->0001_initial.py，0002_XXX.py中的文件，运行“makemigrations”，然后运行“migrate”

    from django.contrib import admin
    from .models import Product, Variation, ProductImage

    # Register your models here.
    admin.site.register(Product)
    admin.site.register(Variation)
    admin.site.register(ProductImage)
