Question

我查看了这个问题Meteor display array inside a collection，但解决方案对我不起作用。我有以下模板：

<template name="remesasList"> 
    <table class="table table-sm" id="remesasList">
        <thead>
            <tr>
                <th>Dia emitido</th>
                <th>Nombre deudor</th>
                <th>Nombre de Factura</th>
                <th>Importe</th>
                <th>Status</th>
            </tr>
        </thead>
        <tbody>
            {{#each remesas}}
                {{> remesa}}
            {{/each}}  
        </tbody>
    </table>   
</template>

我从remesasList.js获取集合remesas：

Template.remesasList.onCreated(function remesasListOnCreated() {

 var self = this;
 self.autorun(function(){
  remesasHandle = self.subscribe('remesas', {
    onError: function (error) { console.log("onError", error.reason); }
  });
  self.state = new ReactiveDict();
  self.state.set("currentdate", new Date().getTime());
});
});

Template.remesasList.helpers({
  remesas() {
    if( remesasHandle && remesasHandle.ready() ) {
    const instance = Template.instance();
      var currentdate = new Date(instance.state.get("currentdate"));
      var firstDay = new Date(currentdate.getFullYear(), currentdate.getMonth(), 1);
      var lastDay = new Date(currentdate.getFullYear(), currentdate.getMonth() + 1, 0);
      console.log(firstDay);
      moment.locale('es');
      return Remesas.find({dia_emitido: {$gte: firstDay, $lte: lastDay}});
    } else {
      console.log("No hay remesas");
    }
  },

我为每个remesa迭代该集合：

<template name="remesa">

  <tr id={{_id}} class="js-row-info">
      <td>{{fecha_default dia_emitido}}</td>
      <td>{{nombre_deudor}}</td>
      <td>{{nombre_factura}}</td>
      <td>{{importe_total}}</td>
      <td>{{boolean_a_si_no pagado}}</td>
  </tr>
  <tr>
  <td>
    <div>
        {{#each item in items}}
            {{item.tipo}}
        {{/each}}
    </div>
  </td>
  </tr>
</template>

我有以下对象remesa，我想显示所有“tipo”字段：

{
 "_id" : "qHDQypADCGodRDFt7",
 "dia_emitido" : ISODate("2017-03-24T23:00:00Z"),
 "nombre_deudor" : "asdsad", 
 "nombre_factura" : "asdsa", 
 "items" : [ 
    { "numeroItem" : 1, "tipo" : "Alquiler", "concepto" : ISODate("2017-02-28T23:00:00Z"), "importe" : 1111 }, 
    { "numeroItem" : 2, "tipo" : "Alquiler", "concepto" : ISODate("2017-02-28T23:00:00Z"), "importe" : 2222 }, 
    { "numeroItem" : 3, "tipo" : "Alquiler", "concepto" : ISODate("2017-09-30T22:00:00Z"), "importe" : 789 }, 
    { "nombre" : "Item 4", "tipo" : "Otro", "concepto" : "un concepto", "importe" : 124578 } 
    ], 
 "numero_de_items" : 4, 
 "importe_total" : 128700 
}

当我运行此代码时出现以下错误：

Exception from Tracker recompute function:
meteor.js?hash=27829e9…:930 Error: {{#each}} currently only accepts arrays, cursors or falsey values.

    at fireCallbacks (blaze.js?hash=813922c…:2013)

为什么每个部分都失败了？我以为那些物品是一个阵列...
