Question

我有autoform创建的门票收藏。创建一个故障单后，我需要上传一个与附件相关的文件。当文件与任何人没有关系时，一切正常。但是当我尝试使用当前对象ID在集合中添加字段时，不会出现任何内容。我的代码：

收集：

tickets = new Mongo.Collection("tickets");
var Schemas = {};
Schemas.tickets = new SimpleSchema({

    title: {
      type: String,
      label: "Titolo"
    },
    description: {
      type: String,
      label: "Descrizione"
    },
    deadline: {
      type: Date,
      label: "Deadline prevista"
    },
    user: {
      type: String,
      autoValue:function(){ return this.userId; }
    },
    status: {
      type: String,
      autoValue: function(){ return "open"; }
    }

});

tickets.attachSchema(Schemas.tickets);

SimpleSchema.messages({
  "required title": "Il [label] è richiesto",
  "required description": "La [label] è richiesta",
  "required deadline": "La [label] è richiesta"
});
//
Files = new FS.Collection("Files", {
  stores: [new FS.Store.FileSystem("Files", {path: "~/uploads"})]
});

和模板：

Template.dashboard.events({
  'click #fileUpload' : function(event, template) {
    var file = template.find('.myFileInput').files[0];
    var ticket = this._id;
      Files.insert(file, function (err, fileObj) {
        if (err) {
          console.log(err);
        } else {
          console.log(ticket);
          tickets.update({_id: ticket}, {$push: {files: ticket}});
        }
      });
  }
});

如果您有任何其他方法建议我，请告诉我。

这有助于：https://github.com/CollectionFS/Meteor-CollectionFS#storing-fsfile-references-in-your-objects

或者，您可以为文件集合创建“元数据”字段，然后将其与故障单集合连接起来：

Template.dashboard.events({
  'click #fileUpload' : function(event, template) {
    var file = template.find('.myFileInput').files[0];
    var ticket = this._id;
    var newFile = new FS.File(file);
    newFile.metadata = {
        ticketId: ticket //ticket id - so you know that this file is from particular ticket, you can then find it by Files.find({'metadata.ticketId': ticket});
    };
      Files.insert(newFile, function (err, fileObj) {
        if (err) {
          console.log(err);
        }
      });
  }
});
