数据库中的IntegrityError在django中存储的值吗？

Question

“”“

我的问题是数据库的值不能正确地存储在下面我上传的视图函数文件中，模型文件作为图像。因此，在模型中有三个字段，但数据库只存储图像，默认情况下存储其他值，获取空值，因此您可以帮助解决我的问题。

Answer 1

您正在尝试从uploadoc视图中名为POSTed的userProblemModel数据中设置c变量。

c = request.POST.get('userProblemModel')

但是在HTML端的表单中，没有命名为userProblemModel的输入标记。这就是在c变量中获取None值的原因。
