python - 谷歌应用程序引擎(Python): Using multiple forms on a single web page

Question

我在一个网页上有两个表单，其内容在分别提交时存储在两个不同的数据库中。

这是包含两种不同形式的源代码:

<form method = "post">
To:<input type = "text" name = "to"><br>
Amt:<input type = "text" name = "to_amt"> <br>
<input type = "submit">
</form>

<br>

<form method = "post">
By:<input type = "text" name = "by"><br>
Amt:<input type = "text" name = "by_amt"> <br>
<input type = "submit">
</form>

现在，当我从网页提交表单时，相关处理程序如何知道调用了哪个表单的 post 方法？当我在 main.py 文件中提交一个表单的内容时，如何区分这两个表单？

PS:我不想根据我提交的表单将应用程序的控件重定向到两个不同的 URL。还有其他替代解决方案吗？

Answer 1

添加一个隐藏字段来标识提交的表单，然后对代码进行适当的分支。

带注释的表单:

<form method = "post">
    To:<input type = "text" name = "to"><br>
    Amt:<input type = "text" name = "to_amt"> <br>
    <input type = "hidden" name = "form_name" value = "first">
    <input type = "submit">
</form>

然后只需检查您的处理程序:

def post(self):
    if self.request.get('form_name') == 'first':
        # the first form was submitted
