有人能告诉我如何防止在Django模型中存储多个输入的空白输入字段吗

Question

在我的表单中有多个输入字段，这意味着有两个字段集，其中有相同的输入字段，我想将这两个输入存储到不同id中的模型中。它是有效的，但当我只填写了一个输入字段并点击提交按钮时，第二个字段也被存储为空白，但我想阻止它。这意味着我只想将填写的输入字段存储到模型中，而空白字段不会被存储。

我的表单.html

<form class="well form-horizontal" method="post" action="{% url 'fixed_doclist' %}">

Answer 1

由于您只想在提供了所有字段的情况下创建一个Doc实例，因此应该只检查是否为所有字段设置了某些内容。由于您可能没有两个Doc实例的数据，因此不需要批量创建。

例如：

def fixed_doclist(request):
print("Form is submitted successfully!")
doc_args = {
dname: request.POST.get("dname", False), 
exp: request.POST.get("exp", False), 
renewdt: request.POST.get("renewdt", False), 
purpose: request.POST.get("purpose", False), 
remark: request.POST.get("remark", False)
}
doc1_args = {
dname: request.POST.get("dname1", False), 
exp: request.POST.get("exp1", False), 
renewdt: request.POST.get("renewdt1", False), 
purpose: request.POST.get("purpose1", False), 
remark: request.POST.get("remark1", False)
}
if all(doc_args.values()):
Doc.objects.create(**doc_args)
if all(doc1_args.values()):
Doc.objects.create(**doc1_args)
return render(request,'fixeddoclist.html')
