Question

我的MongoDB查询结果受会话值的影响，例如recipientsDetails.find({ paymentStatus:{$in: Session.get('pendingFilter')} }).fetch();

设置这些 pendingFilter会话值以启用过滤结果，从而仅需要集合中的特定值，例如仅显示：成功付款的交易，失败的交易或冲销的交易等

默认情况下，pendingFilter会话值为空，因此，当我的页面第一次加载时，整个集合（未过滤的）都会显示，但是在我使用了各种过滤后的功能之后，现在想返回整个集合未过滤的默认状态，显示为失败。有人可以帮忙解释为什么这不起作用并提供解决方案吗？

下面是我实际的MongoDB查询的样子，其后是yield：

var userIdCode = Meteor.userId(); 
var phoneNumber = Meteor.users.findOne({_id: userIdCode }, { fields: { "profile.telephoneNumber": 1 } },  {sort: {paymentDate: -1 }} ); 
var usersPhoneNumber = phoneNumber.profile.telephoneNumber; 

recipientsDetails.find({ 
                          paymentStatus:{                                                                            
                             $in: Session.get('pendingFilter')
                             },
                          recipientPaymentStatus: {
                              $in: Session.get('pendingFilter')
                             }
                        },                                                       
                        { $or: [ { payersNumber: usersPhoneNumber },                                                                 
                        { recipientNumber: usersPhoneNumber } ] }, 

                        {sort: {paymentDate: 'desc' }}).fetch();

上面的查询产量：

0:
  payersName: "Sa Acea"
  payersNumber: "+254705087633"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Success"
  recipientPaymentStatus: "Reversed"
  recipientNumber: "+254705087633"
  _id: "D3gY4BoR2tvxdK4xv"
1:
  payersName: "Paul Acea"
  payersNumber: "+254705557688"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Pending"
  recipientPaymentStatus: "Success"
  recipientNumber: "+254705087633"
  _id: "ajCjYbLaDP7x4iAFK"
2:
  payersName: "Simon Bolton"
  payersNumber: "+25470887633"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Success"
  recipientPaymentStatus: "Complete"
  recipientNumber: "+254705087633"
  _id: "K4d6wDrjRRdSyCkhW"

我有三个过滤器函数，它们在单击时仅显示指定的集合值。如下所示：

  'click .reversedSubMenu' (event, instance) {
      event.preventDefault();
      Session.set('pendingFilter', [ "Success", "Reversed" ]);
    },

这正确地产生了：

0:
  payersName: "Sabiti Asea"
  payersNumber: "+254705087633"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Success"
  recipientPaymentStatus: "Reversed"
  _id: "D3gY4BoR2tvxdK4xv"

。

   'click .inPescrowSubMenu' (event, instance) {
      event.preventDefault();
      Session.set('pendingFilter', [ "Success", "Pending" ]);
    },

这正确地产生了：

0:
  payersName: "Paul Asea"
  payersNumber: "+254705557688"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Pending"
  recipientPaymentStatus: "Success"
  _id: "ajCjYbLaDP7x4iAFK"

。

   'click .paidSubMenu' (event, instance) {
      event.preventDefault();
      Session.set('pendingFilter', [ "Success", "Complete" ]);
    },

这也可以正确产生：

0:
  payersName: "Simon Bolton"
  payersNumber: "+25470887633"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Success"
  recipientPaymentStatus: "Complete"
  _id: "K4d6wDrjRRdSyCkhW"

此处的问题是下面的.reset函数无法按设计运行。单击后，pendingFilter会话将重置为null，但是我无法根据需要查看整个集合。

   'click .reset' (event, instance) {
      event.preventDefault();
      Session.set('pendingFilter', []);
      var testing = Session.get('pendingFilter');
      console.log("Testing PendingFilter: " +testing )
    },

上面在浏览器控制台中产生：Testing PendingFilter:

单击.reset后，期望的结果是使该结果显示整个/未过滤的大学，如下所示：

0:
  payersName: "Sabiti Asea"
  payersNumber: "+254705087633"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Success"
  recipientPaymentStatus: "Reversed"
  recipientNumber: "+254705087633"
  _id: "D3gY4BoR2tvxdK4xv"
1:
  payersName: "Paul Asea"
  payersNumber: "+254705557688"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Pending"
  recipientPaymentStatus: "Success"
  recipientNumber: "+254705087633"
  _id: "ajCjYbLaDP7x4iAFK"
2:
  payersName: "Simon Bolton"
  payersNumber: "+25470887633"
  paymentDate: "2019-03-28 22:38:30"
  paymentStatus: "Success"
  recipientPaymentStatus: "Complete"
  recipientNumber: "+254705087633"
  _id: "K4d6wDrjRRdSyCkhW"

如何制定我的重置功能/或查询以启用上述期望的结果？

预先感谢

我不知道为什么我没有早点弄清楚这个，但是我要做的 RESET 只是将所有数组值添加到会话中，如下所示：< / p>

   'click .reset' (event, instance) {
      event.preventDefault();
      Session.set('pendingFilter', [ "Pending", "Complete", "Success", "Reversed" ]);
      var testing = Session.get('pendingFilter');
      console.log("Testing PendingFilter: " +testing )
    },

如何在查询中重置会话以再次显示整个集合？
