如何在Django管理页面中包含内嵌引导日历选择器？

我正在根据以下内容创建自定义表单和模板：Django admin add custom filter 它适用于文本字段。我想将日历添加到此。

如何包含此特定表单的JS和CSS文件？
如何将选择的值传递给表单？

YearMonthForm

class YearMonthForm(forms.Form):
        def __init__(self, *args, **kwargs):
            self.field_name = kwargs.pop('field_name')
            super(YearMonthForm, self).__init__(*args, **kwargs)
            self.fields['%s__gte' % self.field_name] = forms.DateField()

YearMonthFilter

class YearMonthFilter(admin.filters.FieldListFilter):
    template = 'maindashboard/filter.html'

    def __init__(self, *args, **kwargs):
        field_path = kwargs['field_path']
        self.lookup_kwarg_since = '%s__gte' % field_path
        super(YearMonthFilter, self).__init__(*args, **kwargs)
        self.form = YearMonthForm(data=self.used_parameters, field_name=field_path)

    def expected_parameters(self):
        return [self.lookup_kwarg_since]

    # no predefined choices
    def choices(self, cl):
        return []

    def queryset(self, request, queryset):
        if self.form.is_valid():
            filter_params = {
                p: self.form.cleaned_data.get(p) for p in self.expected_parameters()
                if self.form.cleaned_data.get(p) is not None
            }

            startBillingDate = filter_params["billingDate__gte"]
            year = startBillingDate.year
            month = startBillingDate.month
            day = calendar.monthrange(startBillingDate.year, startBillingDate.month)[1]
            endDate = date(year, month, day)
            filter_params["billingDate__lte"] = endDate

            return queryset.filter(**filter_params)
        else:
            return queryset

filter.html

{% load i18n admin_static %}
<h3>{% blocktrans with filter_title=title %} By {{ filter_title }} {% endblocktrans %}</h3>

{% with choices.0 as i %}

    <label>Filter by Year-Month:</label>
    <div id='InlineMenu'></div>

<form method="GET" action="">
    {{ spec.form.media }}
    {{ spec.form.as_p }}
    <p class="submit-row">
        {# create hidden inputs to preserve values from other filters and search field#}
        {% for k, v in i.get_query.items %}
                <input type="hidden" name="{{ k }}" value="{{ v }}">
        {% endfor %}
    <input type="submit" value="{% trans "Search" %}">
    <input type="reset" value="{% trans "Clear" %}">
    </p>
</form>

{% endwith %}

我不确定{{spec.form.media}}标签的作用。但是我在其他示例中也看到过，它们向表单添加了媒体功能。

文件夹结构 文件夹结构：

 -projectportal
     - maindashboard
     - templates
         - filter.html
     - static
         - maindashboard
             - css
                 - MonthPicker.min.css
             - js
                 - monthPicker.js
                 - monthPicker.min.js

如何为此特定形式引用css和js文件？

更新

弄清楚如何引用此表单/模板的JS和CSS文件。但是，整个“管理”页面现在的样式有所不同。日历现在显示在管理过滤器下。现在，我需要弄清楚如何捕获日期更改事件并提交表单。

@property
    def media(self):
        return forms.Media(
            css= {'all': ('maindashboard/css/bootstrap.min.css', 'maindashboard/css/bootstrap-theme.min.css', 'maindashboard/css/bootstrap-datepicker.min.css',)},
        js = ('maindashboard/js/jquery-3.3.1.slim.min.js', 'maindashboard/js/bootstrap.min.js', 'maindashboard/js/bootstrap-datepicker.js', 'maindashboard/js/bootstrap-datepicker.min.js', 'maindashboard/js/monthPicker.js'))

Answer 1

css和js文件是从YearMonthForm类中的media方法引用的。

在“ monthPicker.js”文件中提交的表单之后，将传递所选的“年月”。

$("#InlineMenu").datepicker().on("changeDate", function(e){
// Increase month by 1
$("#id_billingDate__gte").val(e.date.getFullYear() + "-" + (e.date.getMonth()+1) + "-1");
$("#billing_calendar").submit();

}）;

如何实现Bootstrap DatePicker（年/月）到Django管理员过滤器？
