我有一个在PC上缓慢建立的项目，它运行正常。我只是想将其放到服务器上，但出现此错误：
django.db.utils.ProgrammingError：关系“ django_content_type”确实 不存在
我无法解决该问题，Stackoverflow上的帖子建议删除并重新创建迁移，我做了，但是存在相同的问题。如果您能指导我寻找的东西，我将不胜感激。
这是我的追踪记录：

EDIT添加了ApplicationForm
class ApplicationForm(forms.ModelForm):
class Meta:
model = Application
exclude = ['applied_at']
widgets = {
'job' : forms.HiddenInput(),
'user' : forms.HiddenInput(),
'apply_name' :forms.TextInput(attrs={ "class" : 'form-control'}),

'apply_cv' : forms.FileInput(attrs={'class' : 'form-control',
'id' : 'input-file'}),
'ip_address' : forms.HiddenInput()
}
答案 0 :(得分：0)
Alain对它进行了排序。
这是在第一次迁移时发生的。
问题是urls.py。
将url_patterns = [...]包围在try-Except构造中，并在Exception部分中设置urlpatterns = []。您的错误可能正在发生，因为您的代码正试图对尚未建立的数据库执行操作。
