Question

根据以下规则，我得到了一个缺失或不充分的权限错误，但仅用于更新。我可以创建新文档，但任何更新写入都被拒绝。我错过了什么？

match /msgs/{msgs} {
allow create: if request.resource.data.keys().hasAll(["name", "msg", "status", "time"]) &&
                request.resource.data.size() == 4 &&
                request.resource.data.name is string &&
                request.resource.data.msg is string &&
                request.resource.data.status is string &&
                request.resource.data.status == "new" || "viewed" &&
                request.resource.data.time is timestamp;
allow update: if request.resource.data.size() == 1 &&
                request.resource.data.keys().hasAll(["status"]) &&
                request.resource.data.status is string &&
                request.resource.data.status == "new" || "viewed";
}

我的更新代码非常简单：

docRef.update({
        status: "viewed"
    })

Answer 1

我认为这里的问题是在update上，尺寸不是＆＃39; t＆＃34;正在更新的字段数＆＃34;而是更新后的对象大小应用于请求，但在提交更新之前＃34;。这意味着request.resource.data是＆＃34;水合＆＃34;除了正在编写的内容之外，还有现有的字段/值。然后，您将检查以确保只有一个字段在变化。

这意味着您的规则可能如下：

allow update: if request.resource.data.size() == resource.data.size() &&
                 request.resource.data.name == resource.data.name &&
                 request.resource.data.msg == resource.data.msg &&
                 request.resource.data.time == resource.data.time &&
                 request.resource.data.status == "new" || "viewed";

收到Firebase支持团队的解决方案。事实证明，您需要使每个.data.key值声明分开且不同。所以正确的观察员才能完成这条规则：

func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath){
   if editingStyle == UITableViewCellEditingStyle.delete {
      let delete: NSFetchRequest<Messages> = Messages.fetchRequest()
      do { 
          var deleteMessage = try
          PersistenceServce.context.fetch(delete)
          PersistenceServce.context.delete(messages.remove(at: indexPath.row))
          PersistenceServce.saveContext()
          self.messages = deleteMessage
          SavedMessages.reloadData()
      } catch {}
   }
}

是这样的：

var map = null;
var markers = [];
var infowindow = new google.maps.InfoWindow()

function clickOpenInfowindow (id) {
  // find the marker by id
  var marker = markers.find ( m => m.id === id)
  if (marker) {
      var content = '<h3>' +  marker.name + '</h3>';
      content += marker.address + '<br>';
      content += maker.phone;

      var clickaction = "click";

      //check if mobile
      if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera 
      Mini/i.test(navigator.userAgent) ) {
        clickaction = "click";
     } else { 
       clickaction = "mouseover";
     }

    infowindow.setContent(content);
    infowindow.open(map, marker);
  }
}

function addMarker(info, icon) {
  var location = {lat: info.lat, lng: info.lng};
  var marker = new google.maps.Marker({
    position: location,
    icon: 'map/images/pin-icon-' + icon + '.png',
    map: map
  });

  // save info content to marker
  marker.id = info.id
  marker.name = info.name
  marker.addree = info.address
  marker.phone = info.phone

  var content = '<h3>' +  info.name + '</h3>';
  content += info.address + '<br>';
  content += info.phone;

  clickaction = "click";

   //check if mobile
   if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera 
     Mini/i.test(navigator.userAgent) ) {
     clickaction = "click";
   } else { 
     clickaction = "mouseover";
   }

  google.maps.event.addListener(marker, clickaction, function() {
    infowindow.setContent(content);
    infowindow.open(map,marker);

  });

 markers.push(marker);

}


function addMarkerPerCategory(category) {
  deleteMarkers();

  if (category == 'ALL') {
    for (var i = 0; i < mapPinInfo.restaurants.length; i++) {
      addMarker(mapPinInfo.restaurants[i], 1);
    }
    for (var i = 0; i < mapPinInfo.transportation.length; i++) {
      addMarker(mapPinInfo.transportation[i], 1);
    }
    for (var i = 0; i < mapPinInfo.shopping.length; i++) {
      addMarker(mapPinInfo.shopping[i], 1);
    }
  } else if (category == 'RESTAURANTS') {
    for (var i = 0; i < mapPinInfo.restaurants.length; i++) {
      addMarker(mapPinInfo.restaurants[i], 1);
    }
  } else if (category == 'TRANSPORTATION') {
    for (var i = 0; i < mapPinInfo.transportation.length; i++) {
      addMarker(mapPinInfo.transportation[i], 1);
    }
  } else if (category == 'SHOPPING') {
    for (var i = 0; i < mapPinInfo.shopping.length; i++) {
      addMarker(mapPinInfo.shopping[i], 1);
    }
  } 
}

function initMap() {
  addMarkerPerCategory('ALL');
}

感谢大家的帮助。
