django 用一个提交按钮提交两种不同的表单 [英] django submit two different forms with one submit button

问题描述

是否可以在 django 中使用一个提交按钮提交两种不同的表单?我有一种称为仪器"的表格和 4 种相同的配置"表格.现在我想总是提交一个配置和仪器.例如仪器 + 配置 1 和仪器 + 配置 2. 每个配置都有自己的提交按钮.

is it possible to submit two different forms, with one submit button in django? i have one form called "instrument" and 4 equal forms "config". now i'd like to submit always one config and instrument. e.g. instrument + config 1, and instrument + config 2. and every config have its own submit button.

我用配置表单中的一个按钮尝试过:

i have tried it with one button in the config form:

<input onclick="submitForms()" class="btn btn-primary cfg" type="submit" value="Start" >

并调用一个js函数'onclick':

and call a js function 'onclick':

submitForms = function(){
    console.log('ok'); //only for testing
    document.forms["firstForm"].submit();
    document.forms["secondForm"].submit();
}

这是我在views.py中的方法:

this is my method in the views.py:

if request.method == 'POST':
        form1 = dataproviderInstrumentForm(request.POST)
        form2 = dynamicTimeseriesForm(request.POST)
        print(request.POST)
        if form1.is_valid() or form2.is_valid(): 
            # do some stuff

else:
    form1 = dataproviderInstrumentForm() # an unbound form
    form2 = dynamicTimeseriesForm() # an unbound form

推荐答案

不要在 html 中使用多个

标签，只使用一个 标记并在其下添加所有表单的字段.

Instead of having multiple <form ..> tags in html, use only one <form> tag and add fields of all forms under it.

模板中的示例

<form >
    {{ form1.as_p }}
    {{ form2.as_p }}
    {{ form3.as_p }}
</form>

因此，当用户提交表单时，您将看到所有表单数据，然后您可以在视图中执行您正在执行的操作.作为

So when user submits the form you will get all forms data in view, then you can do what you are doing in view. As

if request.method == 'POST':
        form1 = Form1(request.POST)
        form2 = Form2(request.POST)
        print(request.POST)
        if form1.is_valid() or form2.is_valid(): 

最好使用表单前缀 在这种情况下.

Its better to use form prefix in such cases.

所以你可以这样做

if request.method == 'POST':
        form1 = Form1( request.POST,prefix="form1")
        form2 = Form2( request.POST,prefix="form2")
        print(request.POST)
        if form1.is_valid() or form2.is_valid(): 
else:
        form1 = Form1(prefix="form1")
        form2 = Form2(prefix="form2")
