我正在使用angular bootstrap datetimepicker。我想为过去的日期和时间制作Invitation.objects.filter(...).delete()。
我该怎么做？

我假设您使用的是angular-bootstrap-datetimepicker，因此您需要使用before-render callback。
代码看起来像这样：
function BeforeRender ($dates) {
var activeDate = moment();
$dates.filter(function (date) {
return date.localDateValue() >= activeDate.valueOf()
}).forEach(function (date) {
date.selectable = false;
})
}
自述文件有一个example of a date range picker可以满足您的需要。

正如您在其网站上看到的那样（https://angular-ui.github.io/bootstrap/#/datepicker)，您可以通过配置对象a＆＃34; dateDisabled＆＃34;。
这是示例的html：
<style>
.full button span {
background-color: limegreen;
border-radius: 32px;
color: black;
}
.partially button span {
background-color: orange;
border-radius: 32px;
color: black;
}
</style>
<div ng-controller="DatepickerDemoCtrl">
<pre>Selected date is: <em>{{dt | date:'fullDate' }}</em></pre>
<h4>Inline</h4>
<div style="display:inline-block; min-height:290px;">
<uib-datepicker ng-model="dt" class="well well-sm" datepicker-options="inlineOptions"></uib-datepicker>
</div>
<h4>Popup</h4>
<div class="row">
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" uib-datepicker-popup="{{format}}" ng-model="dt" is-open="popup1.opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" alt-input-formats="altInputFormats" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open1()"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
<div class="col-md-6">
<p class="input-group">
<input type="text" class="form-control" uib-datepicker-popup ng-model="dt" is-open="popup2.opened" datepicker-options="dateOptions" ng-required="true" close-text="Close" />
<span class="input-group-btn">
<button type="button" class="btn btn-default" ng-click="open2()"><i class="glyphicon glyphicon-calendar"></i></button>
</span>
</p>
</div>
</div>
<div class="row">
<div class="col-md-6">
<label>Format: <span class="muted-text">(manual alternate <em>{{altInputFormats[0]}}</em>)</span></label> <select class="form-control" ng-model="format" ng-options="f for f in formats"><option></option></select>
</div>
</div>
<hr />
<button type="button" class="btn btn-sm btn-info" ng-click="today()">Today</button>
<button type="button" class="btn btn-sm btn-default" ng-click="setDate(2009, 7, 24)">2009-08-24</button>
<button type="button" class="btn btn-sm btn-danger" ng-click="clear()">Clear</button>
<button type="button" class="btn btn-sm btn-default" ng-click="toggleMin()" uib-tooltip="After today restriction">Min date</button>
</div>
这是JavaScript：
angular.module('ui.bootstrap.demo').controller('DatepickerDemoCtrl', function ($scope) {
$scope.today = function() {
$scope.dt = new Date();
};
$scope.today();
$scope.clear = function() {
$scope.dt = null;
};
$scope.inlineOptions = {
customClass: getDayClass,
minDate: new Date(),
showWeeks: true
};
$scope.dateOptions = {
dateDisabled: disabled,
formatYear: 'yy',
maxDate: new Date(2020, 5, 22),
minDate: new Date(),
startingDay: 1
};
// Disable weekend selection
function disabled(data) {
var date = data.date,
mode = data.mode;
return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6);
}
$scope.toggleMin = function() {
$scope.inlineOptions.minDate = $scope.inlineOptions.minDate ? null : new Date();
$scope.dateOptions.minDate = $scope.inlineOptions.minDate;
};
$scope.toggleMin();
$scope.open1 = function() {
$scope.popup1.opened = true;
};
$scope.open2 = function() {
$scope.popup2.opened = true;
};
$scope.setDate = function(year, month, day) {
$scope.dt = new Date(year, month, day);
};
$scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];
$scope.format = $scope.formats[0];
$scope.altInputFormats = ['M!/d!/yyyy'];
$scope.popup1 = {
opened: false
};
$scope.popup2 = {
opened: false
};
var tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);
var afterTomorrow = new Date();
afterTomorrow.setDate(tomorrow.getDate() + 1);
$scope.events = [
{
date: tomorrow,
status: 'full'
},
{
date: afterTomorrow,
status: 'partially'
}
];
function getDayClass(data) {
var date = data.date,
mode = data.mode;
if (mode === 'day') {
var dayToCheck = new Date(date).setHours(0,0,0,0);
for (var i = 0; i < $scope.events.length; i++) {
var currentDay = new Date($scope.events[i].date).setHours(0,0,0,0);
if (dayToCheck === currentDay) {
return $scope.events[i].status;
}
}
}
return '';
}
});
注意这一行：
dateDisabled: disabled,
通过在配置对象中传递此功能，可以将功能禁用设置为禁用日期的处理程序。所以在几行后你可以阅读禁用的功能：
// Disable weekend selection
function disabled(data) {
var date = data.date,
mode = data.mode;
return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6);
}
该功能的两个参数是：
date是一个普通的JavaScript日期对象，您可以使用所有date methods来实现此目的。
模式是日期模式，您可以在此示例中看到验证模式是否等于＆＃34; day＆＃34;。
因此，您可以通过这种方式禁用一系列日期或自定义日期。

我最近遇到了这个问题，在阅读了一些stackoverflow答案之后，我想到了以下代码：
这也可以照顾白天，小时和分钟。
$scope.startDateBeforeRender = function($view, $dates, $leftDate, $upDate, $rightDate) {
const minDate = moment().local().startOf($view).valueOf();
for(let i=0; i < $dates.length; i++) {
if($view === 'day' || $view === 'hour') {
if (minDate > $dates[i].localDateValue()) {
$dates[i].selectable = false;
}
} else {
if (minDate >= $dates[i].localDateValue()) {
$dates[i].selectable = false;
}
}
}
};
HTML为：
<md-input-container class="md-block" flex-gt-sm>
<label>Time</label>
<div class="dropdown">
<a class="dropdown-toggle" id="dropdown2" role="button" data-toggle="dropdown" data-target="#" href="javascript:void(0);">
<div class="input-group">
<input type="text" class="form-control" data-ng-model="data.dateDropDownInput"><span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
</div>
</a>
<ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
<datetimepicker data-ng-model="data.dateDropDownInput" data-before-render="startDateBeforeRender($view, $dates, $leftDate, $upDate, $rightDate)" data-datetimepicker-config="{ dropdownSelector: '#dropdown2' }"/>
</ul>
</div>
</md-input-container>
