Question

我有一个叫做agent的猫鼬收藏。我可以使用mongodb控制台查看更新的数据。但是无法使用$ .ajax或$ .get

获取更新的数据

我是nodejs和mongoose的新手。我更新的数据正在mongodb数据库上更新，但即使刷新后也不会在客户端上更新。

将更新后的集合发送到客户端的路由

router.get('/:function', function(req, res) {
  if (req.params.function === 'getWeeklyTarget') {
    helper.getWeeklyTarget().then(values => {
      res.send(values);
    })
  }
})

getWeeklyTarget函数

function getWeeklyTarget() {
    return new Promise((resolve, reject) => {
        // Find Current Week
        let this_month = `${moment().format('MMMM')} ${moment().format('YYYY')}`;
        let this_week;
        let team_targets = [];

        Month.find({name: this_month})
            .then(foundMonth => {
                foundMonth.forEach(month => {
                    if (month.name === this_month) {
                        this_week = month.current_week;
                    }
                    findTeams.then(foundTeams => {
                        let this_week_target = [];
                        foundTeams.forEach(team => {
                            let counter = 0;
                            let another_counter = 0;
                            team.members.forEach(agent => {
                                if (this_week === 'first_week') {
                                    counter += agent.weekly_target.first_week
                                    another_counter += agent.total_sales
                                }else if (this_week === 'second_week') {
                                    counter += agent.weekly_target.second_week
                                    another_counter += agent.total_sales
                                }else if (this_week === 'third_week') {
                                    counter += agent.weekly_target.third_week
                                    another_counter += agent.total_sales
                                } else if (this_week === 'fourth_week') {
                                    counter += agent.weekly_target.fourth_week
                                    another_counter += agent.total_sales
                                }
                            })
                            this_week_target.push({
                                name: team.name,
                                target: counter,
                                achieved: another_counter
                            })
                        })
                        resolve(this_week_target);
                    })
                })
            })
    }) 
}

更新收藏集后，我想将更新的数据提取到客户端

似乎resolve()方法被调用了一次以上，因为它在forEach循环中被调用了。请尝试在this_week_target循环之外声明forEach，并在forEach循环之外也调用resolve()。像这样

function getWeeklyTarget() {
    return new Promise((resolve, reject) => {
        // Find Current Week
        let this_month = `${moment().format('MMMM')} ${moment().format('YYYY')}`;
        let this_week;
        let team_targets = [];

        Month.find({name: this_month})
            .then(foundMonth => {
              let this_week_target = [];
                foundMonth.forEach(month => {
                    if (month.name === this_month) {
                        this_week = month.current_week;
                    }
                    findTeams.then(foundTeams => {
                        foundTeams.forEach(team => {
                            let counter = 0;
                            let another_counter = 0;
                            team.members.forEach(agent => {
                                if (this_week === 'first_week') {
                                    counter += agent.weekly_target.first_week
                                    another_counter += agent.total_sales
                                }else if (this_week === 'second_week') {
                                    counter += agent.weekly_target.second_week
                                    another_counter += agent.total_sales
                                }else if (this_week === 'third_week') {
                                    counter += agent.weekly_target.third_week
                                    another_counter += agent.total_sales
                                } else if (this_week === 'fourth_week') {
                                    counter += agent.weekly_target.fourth_week
                                    another_counter += agent.total_sales
                                }
                            })
                            this_week_target.push({
                                name: team.name,
                                target: counter,
                                achieved: another_counter
                            })
                        })
                    })
                })
                resolve(this_week_target);
            })
    }) 
}

猫鼬不会获取更新的数据，除非重启nodejs
