在Django中存储的数据库中的IntegrityError？

Question

'''

我的问题是数据库值无法正确存储在下面，我将视图功能文件，模型文件分解为图像。因此在模型中有三个字段，但是数据库仅存储图像，默认情况下存储的其他vlaues则为空值，因此您可以帮助解决我的问题。]

Answer 1

您正在尝试从c视图中的名为POSTed数据的userProblemModel中设置uploadoc变量。

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

但是在html端的表单中没有userProblemModel命名输入标签。这就是为什么要在None变量中获得c值的原因。
