使用过滤器将表单提交到 django-admin 模型

我想要一个自定义的 html 表单代码片段，允许用户选择一个“训练”，然后将其用作“参与者”的 django-admin 模型过滤器的查询参数。

我已经在 modeladmin 上成功创建了过滤器：

class ParticipantAdmin(RestrictedModelAdmin):
    list_filter = ('training__name',)

可能值得注意的是 RestrictedModleAdmin 是 ModelAdmin 的子类，它为模型提供行级安全性；登录的用户应该只能看到他们拥有的行。

因此，当仅使用该管理界面时，使用此过滤器的网址看起来像这样：

/admin/core/participant/?training__name=Menno+Ropes

一切都很好。现在我想我应该能够创建一个非常简单的表单，允许选择有效的“训练”并将其作为 GET 提交到 /admin/core/participant/ 。

<form method="GET" action="/admin/core/participant/">{% csrf_token %}
    <ol>
        <li>Select your training:
            <select name='training__name'>
                <option value=''>&mdash;</option>
                {% for training in trainings %}
                <option value='{{ training.name }}'>{{ training }}</option>
                {% endfor %}
            </select>
        </li>
        <li>See participants for that training.
            <input type='submit' name='submit' value='Submit' /></li>
    </ol>
</form>

最后一点似乎不起作用。 django 内部的一些神奇的 foo 似乎总是将提交弄乱：

/admin/core/participant/?e=1

这显然没有选择适当的过滤器值，因此显示了未经过滤的“参与者”列表。

这是怎么回事？我该怎么做才能让它允许我的 GET 参数传递到管理模型？

提前致谢。

I would like to have a custom snippet of html form code that takes allows the user to select a 'training' that is then used as a query parameter to a django-admin model filter for 'participants'.

I've successfully created the filter on the modeladmin:

class ParticipantAdmin(RestrictedModelAdmin):
    list_filter = ('training__name',)

It's probably worth noting that RestrictedModleAdmin is a subclass of ModelAdmin that provides row-level security for the model; logged in users should only see rows they own.

Thus, urls using this filter look something like this when just using that admin interface:

/admin/core/participant/?training__name=Menno+Ropes

All that works great. Now I think I should be able to create a very simple form that allows selecting a valid 'training' and submitting that to /admin/core/participant/ as a GET.

<form method="GET" action="/admin/core/participant/">{% csrf_token %}
    <ol>
        <li>Select your training:
            <select name='training__name'>
                <option value=''>—</option>
                {% for training in trainings %}
                <option value='{{ training.name }}'>{{ training }}</option>
                {% endfor %}
            </select>
        </li>
        <li>See participants for that training.
            <input type='submit' name='submit' value='Submit' /></li>
    </ol>
</form>

This last bit doesn't see to work. Some magic foo in the django innards seems to always mangle the submission to be:

/admin/core/participant/?e=1

This obviously doesn't select the appropriate filter value and thus shows an unfiltered list of 'participants'.

What's going on? What can I do to get it to allow my GET parameter to pass through to the admin model?

Thanks in advance.

问题是您的中有一个 name 属性，导致出现额外的 GET 参数：submit这会引发无效查找错误，因此 e=1

删除 name 属性就可以了。

我做了一个小实验来确认，因为我认为服务器可能以某种方式以不同的方式对待浏览器 GET 很奇怪。

这有点棘手，但对我有用：

def changelist_view(self, request, bill_id, extra_context=None):
    """queryset is an extra parameter"""
    req = request.GET.copy()
    if 'queryset' in req:
        queryset = req.pop('queryset')[0]
    else:
        queryset = request.META['HTTP_REFERER'].split('queryset=')[1]
        url = "/admin/billing/invoice/%s/select_to_move/?%s&queryset=%s" % (bill_id, request.GET.urlencode(), queryset)
        return HttpResponseRedirect(url)  
    request.GET = req
    # Do stuff with queryset.
    return super(MyAdminClass, self).changelist_view(request, context)

It's a little bit tricky, but it works for me:

def changelist_view(self, request, bill_id, extra_context=None):
    """queryset is an extra parameter"""
    req = request.GET.copy()
    if 'queryset' in req:
        queryset = req.pop('queryset')[0]
    else:
        queryset = request.META['HTTP_REFERER'].split('queryset=')[1]
        url = "/admin/billing/invoice/%s/select_to_move/?%s&queryset=%s" % (bill_id, request.GET.urlencode(), queryset)
        return HttpResponseRedirect(url)  
    request.GET = req
    # Do stuff with queryset.
    return super(MyAdminClass, self).changelist_view(request, context)
