问题: 我有许多组,每个组都有属于不同组的成员。每个成员在每个组中都有一个头衔(角色)。我正在尝试列出所有组并显示组中的每个成员及其标题。我正在使用 reywood:publish-composite,一切正常,除了我无法显示每个成员的标题。我认为问题出在 Template.groupMembers.helpers 文件中
title: function() {
console.log(this.roleId); // this shows up in the console for each member
return Titles.findOne({titleId: this.roleId}); // but this doesn’t work
},
收藏:
groups {
"_id" : "xFSzAHBEps2dSKcWM",
"name" : "Generic Group",
"logo" : "generic-logo-hi.png"
}
members {
"_id" : "vyDtiaKKukZYQdFvs",
"groupId" : "xFSzAHBEps2dSKcWM",
"memberId" : "hRx8GBTyB5X8iQQ52",
"roleId" : "1"
}
Meteor.users {
"_id" : "hRx8GBTyB5X8iQQ52",
"profile" : {
"name" : "Bob Lorros"
},
}
titles {
"_id" : "bYsKpsyYtyKR8NYpm",
"titleId" : 1,
"title" : "Staff (non-voting)"
}
