一页多个表单上的Django值错误
我在一个模板上有一个表单，每当我点击提交按钮，我就会被重定向到一个抛出值错误的页面。我曾尝试在网上搜索帮助，但没有成功，另一个表单在模板上运行得非常好，只是文档表单。我在网上搜索了处理一个模板上的多个表单，发现了一组类似这样的代码。但由于一些奇怪的原因，我无法让它工作，我试图为我的第二个表单编写一个单独的视图，但没有运气。我对django还是个新手一页多个表单上的Django值错误,django,Django,我在一个模板上有一个表单，每当我点击提交按钮，我就会被重定向到一个抛出值错误的页面。我曾尝试在网上搜索帮助，但没有成功，另一个表单在模板上运行得非常好，只是文档表单。我在网上搜索了处理一个模板上的多个表单，发现了一组类似这样的代码。但由于一些奇怪的原因，我无法让它工作，我试图为我的第二个表单编写一个单独的视图，但没有运气。我对django还是个新手 def modify_land(request, pk): # Query Sets land = get_object_or_40
