请查看我通过事件检查问题的方式
@Get('视图/用户/事件')
异步查找所有事件（
@Req() req: Request,
@Res() res: Response,
@Query('page') page: number = 1,
@Query('limit') limit: number = 10,
@Query('name') name?: string,
@Query('type') type?: string,
）{
try {
if (req.cookies.user_jwt) {
return res.redirect('users-events');
}
const response = await this.eventsService.findAll(page, limit, name, type);
// console.log(response.events);
return res.render('users-events', {events: response.events, current: page, pages: response.pages, messages: req.flash() });
} catch (error) {
if (error instanceof NotFoundException) {
req.flash('error', error.message);
return res.render('users-events');
} else {
console.error('Error retrieving events:', error);
req.flash('error', error.message);
return res.render('users-events');
}
}
}
async findAll(页：数量 = 1，限制：数量 = 10，名称？：字符串，类型？：字符串) {
try {
const currentDate = new Date();
const skip = (page - 1) * limit;
const query: any = { event_date: { $gte: currentDate } };
if (name || type) {
query.$or = [];
if (name) {
query.$or.push({ event_name: { $regex: new RegExp(name, 'i') } });
}
if (type) {
query.$or.push({ event_type: { $regex: new RegExp(type, 'i') } });
}
}
const events = await this.eventModel
.find(query)
.select('_id image_url event_name event_type description location sponsors event_date')
.skip(skip)
.limit(limit)
.exec();
if (!events || events.length === 0) {
throw new NotFoundException('There are no upcoming events at this time.');
}
// Calculate total pages
const totalPages = Math.ceil(events.length / limit);
return {
message: 'Events retrieved successfully.',
totalPages: totalPages,
pages: `${page} of ${totalPages}`,
events: events,
statusCode: HttpStatus.OK
}
} catch (error) {
if (error.name === 'NotFoundException') {
throw new NotFoundException(error);
} else {
console.error('Error retrieving events:', error);
throw new Error('Error retrieving events.');
}
}
}
这是车把页面
{{#每个事件}}
{{this.event_name}}
{{这个.描述}}
{{这个位置}}
{{this.event_date}}
{{this._id}}
{{/每个}}
{{#每个事件}}
{{this.event_name}}
{{这个.描述}}
{{这个位置}}
{{this.event_date}}
{{this._id}}
这是对象数组
[
{
_id: new ObjectId('65fb4479787dbd450bb0f640'),
image_url: 'https://res.cloudinary.com/ddl8i/image/upload/v1710922731/aubjuene3kjkiaggenmu.png',
event_name: 'Dev Fest',
event_type: 'Tech',
description: 'Coding is magic',
location: 'Lagos',
sponsors: [],
event_date: 2024-04-04T00:00:00.000Z
}
]
是的，我找到了答案。
只需将 .lean() 添加到查找中
