birth_date 应该是数据库中的必填字段。
我试着在 user.save 之前分配 birth_date 就像
这个：
def signup(self, request, user):
self.cleaned_data['password1'] = 'unknown'
print("Birth date", self.cleaned_data['birth_date'])
user = super(CustomSignupForm, self).save(commit=False)
password = User.objects.make_random_password()
user.set_password(password)
user.birth_date = self.cleaned_data['birth_date']
user.save()
return user
但我仍然得到同样的错误。
仅当我从 table 中删除“birth_date”并迁移时它才得到修复。但这不是我想要的解决方案，因为我想要一个 birth_date 字段，这是必需的。
我尝试调试，但我看不到 cleaned_data 集合中的内容。
我不明白为什么会出现此错误。
如何修复此错误？
似乎由于您在用户 class 中设置 birth_date 属性的方式而引发此错误。您设置了 null=False 和 blank=True，所以我假设 NOT NULL 约束失败，因为您试图将字段设置为 None，而由于 blank=True 而不允许这样做.我建议在您对 birth_date 的定义中删除一个或另一个，但如果能看到 cleaned data 里面的内容，就可以知道传递给 Django 的到底是什么。
我找到原因了。一开始我以为它保存了所有其他数据，但事实并非如此。它不保存任何数据。我在网上遵循了一些 allauth 指南并使用了 def signup()，我应该只使用 def save()。我在网上找到了解决方案：

user = super(CustomSignupForm, self).save(commit=False)
password = User.objects.make_random_password()
user.set_password(password)
user.birth_date = self.cleaned_data['birth_date']
user.save()
return user
但我仍然得到同样的错误。
仅当我从 table 中删除“birth_date”并迁移时它才得到修复。但这不是我想要的解决方案，因为我想要一个 birth_date 字段，这是必需的。
我尝试调试，但我看不到 cleaned_data 集合中的内容。 我不明白为什么会出现此错误。
如何修复此错误？
似乎由于您在用户 class 中设置 birth_date 属性的方式而引发此错误。您设置了 null=False 和 blank=True，所以我假设 NOT NULL 约束失败，因为您试图将字段设置为 None，而由于 blank=True 而不允许这样做.我建议在您对 birth_date 的定义中删除一个或另一个，但如果能看到 cleaned data 里面的内容，就可以知道传递给 Django 的到底是什么。
我找到原因了。一开始我以为它保存了所有其他数据，但事实并非如此。它不保存任何数据。我在网上遵循了一些 allauth 指南并使用了 def signup()，我应该只使用 def save()。我在网上找到了解决方案：
