django - 当视图需要参数时，表单操作参数中包含什么？

发布于 2024-10-27 04:25:54 字数 775 浏览 0 评论 0原文

这就是我所拥有的：

myview.py，其视图采用参数user：

def myview(request, user):
   form = MyForm(request.POST)
   ....
   return render_to_response('template.html',locals(), context_instance=RequestContext(request))

user通过网址传递。

urls.py：

...

urlpatterns += patterns('myview.views',
    (r'^(?P<user>\w+)/', 'myview'),
)

...

我还有一个带有表单的 template.html：

<form name="form" method="post" action=".">
...
</form>

如果 myview 函数需要参数，表单操作参数中会包含什么内容？

现在我有 action="." 。我问的原因是因为当我填写表单（templates.html）并单击提交按钮时，我绝对没有看到从该表单传递的字段值。当我单击提交按钮时，这几乎就像我传递了一个空表单。有什么想法吗？谢谢你！

This is what I have:

myview.py with a view that takes a parameter user:

def myview(request, user):
   form = MyForm(request.POST)
   ....
   return render_to_response('template.html',locals(), context_instance=RequestContext(request))

The user gets passed through an url.

urls.py:

...

urlpatterns += patterns('myview.views',
    (r'^(?P<user>\w+)/', 'myview'),
)

...

I also have a template.html with a form:

<form name="form" method="post" action=".">
...
</form>

What goes in the the form action parameter if myview function requires a parameter?

Right now I have action="." . The reason I'm asking is because when I fill up the form In (templates.html) and click the submit button I see absolutely no field values passed from that form. It's almost like I'm passing an empty form when I click the submit button. Any ideas? Thank you!

如果您想显式设置操作，假设您的模板中有一个变量 username，

<form name="form" method="post" action="{% url myview.views username %}">

或者您可以在 urls.py 中为 url 分配一个名称，这样您就可以像这样引用它：

# urls.py
urlpatterns += patterns('myview.views',
    url(r'^(?P<user>\w+)/', 'myview', name='myurl'), # I can't think of a better name
)

# template.html
<form name="form" method="post" action="{% url myurl username %}">

If you want to explicitly set the action, assuming you have a variable username in your template,

<form name="form" method="post" action="{% url myview.views username %}">

or you could assign a name for the url in your urls.py so you could reference it like this:

# urls.py
urlpatterns += patterns('myview.views',
    url(r'^(?P<user>\w+)/', 'myview', name='myurl'), # I can't think of a better name
)

# template.html
<form name="form" method="post" action="{% url myurl username %}">

您将发布到也提供该表单的同一视图。因此，首先，视图被调用并为表单服务。当您发布表单时，会调用相同的视图，但这次您要处理表单。这就是为什么动作是空的。

它不应该要求任何东西。假设您位于以下网址：

www.yoursite.com/users/johnsmith/

您的表单应为：

<form name="form" method="post" action="">

此时，您已经在 myview 中，用户为 johnsmith。您的视图应如下所示：

if request.method == 'POST':
    form = MyForm(request.POST)
    if form.is_valid():
        # you should be able to extract inputs from the form here
else:
    form = MyForm()

It should not require anything. Assuming you are at the following url:

www.yoursite.com/users/johnsmith/

Your form should be:

<form name="form" method="post" action="">

At this point, you are already in myview with user johnsmith. Your view should look like the following:

if request.method == 'POST':
    form = MyForm(request.POST)
    if form.is_valid():
        # you should be able to extract inputs from the form here
else:
    form = MyForm()
