流星发布异常：使用 aldeed:tabular 时未在发布期间检查（）所有参数

Question

我有以下出版物：

Meteor.publish( 'usersadmin', function() {
  return Meteor.users.find( {}, { fields: { "emails": 1, "roles": 1, "profile": 1 } } )
});

并且我在以下 table 中使用 aldeed:tabular 显示该出版物：

TabularTables.UsersAdmin = new Tabular.Table({
      name: "User List",
      collection: Meteor.users,
      pub: "usersadmin",
      allow: function(userId) {
        return Roles.userIsInRole(userId, 'admin');
      },
      columns: [{
        data: "emails",
        title: "Email",
        render: function(val, type, doc) {
          return val[0].address;
        }
      }, {
        data: "roles",
        title: "Roles",
        render: function(val, type, doc) {
          return val[0]._id;
        }
      }]);

table 显示正常，但在服务器端出现以下异常：

 Exception from sub usersadmin id 2d7NFjgRXFBZ2s44R Error: Did not check() all arguments during publisher 'usersadmin'

这是什么原因造成的？

Answer 1

您收到此错误是因为您需要使用 check(value, pattern).

检查传递给 usersadmin 发布函数的参数

在aldeed:tabular包中实现的响应式数据表，将参数tableName、ids和fields传递给发布功能；这就是抛出异常的原因。

根据documentation，您需要满足以下要求：

Your function:

MUST accept and check three arguments: tableName, ids, and fields

MUST publish all the documents where _id is in the ids array.

MUST do any necessary security checks

SHOULD publish only the fields listed in the fields object, if one is provided.

MAY also publish other data necessary for your table

这应该可以修复错误：

Meteor.publish('usersadmin', function(tableName, ids, fields) {
  check(tableName, String);
  check(ids, Array);
  check(fields, Match.Optional(Object));
  return Meteor.users.find({}, {fields: {"emails": 1, "roles": 1, "profile": 1}});
});
