Question

我想在一个页面上有多个表单。到目前为止，我有一个简单的表单，用户输入数字并返回一个数字。当我试图在同一页面上添加另一个表单（我的模型中将是Post2）时，我无法。我最终得到了两次相同的表格。

所有帮助表示赞赏。

进行编辑添加以尝试使第二个表单正常工作 urls.py

{% load staticfiles %}


<form action="" method="POST">
    {% csrf_token %}
    {{ form.as_p }}

    <input type="submit" value="Submit" name="form1"/>
</form>

<form action="" method="POST">
    {% csrf_token %}
    {{ form.as_p }}

    <input type="submit" value="Submit" name="form2"/>
</form>


... 


{{ round1 }}
{{ round2 }}
{{ round3 }}
{{ betround1 }}
{{ betround2 }}
{{ betround3 }}

<br>
its the same as {{ thesameas }}

Answer 1

您有两个单独的视图，它们只返回特定的表单。在你的模板中，你重复代码，因此你得到它两次。返回支持任意数量的表单。在您的视图中，您可以这样做：

form1 = AmatForm()
form2 = AmatForm2()

args = {
'form2' = form1
'form2' = form2
}
return render(request, self.template_name, args)

然后，您可以在模板中使用：

{{ form1.as_p }}
{{ form2.as_p }}

我建议将表单字段设为可选，然后检查是否输入了任何数据，否则会遇到空表单字段的问题。

Django初学者表单，不能使两个表单在一个模板页面上工作
