我遇到了与EJS中两个或多个填充的集合中的渲染相关的问题。
为了传递我的问题"的最丰富的背景,我将在这里与您分享我的一些代码:模型,路线和视图。
模型架构
var mongoose = require("mongoose");
var playerSchema = mongoose.Schema({
namePlayer: String,
email: String,
playerTeam: {
id: {
type: mongoose.Schema.Types.ObjectId,
ref: "Team"
},
nameTeam: String
}
});
var coachSchema = mongoose.Schema({
nameCoach: String,
email: String,
nameTeams: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Team"
}
]
});
var teamSchema = mongoose.Schema({
nameTeam: String,
teamPlayers: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Player"
}
],
teamCoaches: [
{
type: mongoose.Schema.Types.ObjectId,
ref: "Coach"
}
]
});
module.exports = mongoose.model("Player", playerSchema);
module.exports = mongoose.model("Coach", coachSchema);
module.exports = mongoose.model("Team", teamSchema);
路由器架构
var express = require("express");
var passport = require("passport");
var router = express.Router();
var Player = require("../models/player");
var Team = require("../models/team");
var Coach = require("../models/coach");
// Find Team by ID
router.get("/resultTeam", function (req, res, next) {
var teamId = req.query.team;
Team.findById(teamId).populate("teamPlayers").populate("teamCoaches").exec(function(err, currentTeam) {
if(err){
console.log(err);
} else {
console.log(currentTeam);
res.render("./player/resultTeam", {teams: currentTeam });
}
});
});
的console.log(currentTeam)
{ teamPlayers:
[ { equipe: [Object],
_id: 5b20023443589331491e0903,
namePlayer: 'Zico',
email: 'lorem@ipsum.com',
__v: 0 },
{ equipe: [Object],
_id: 5b215e6460adc33528d29f06,
namePlayer: 'Pelé',
email: 'lorem@ipsum.com',
__v: 0 } ],
teamCoaches:
[ { equipes: [Object],
_id: 5b1f063b999c3c285aa9f3e7,
nameCoach: 'Harrison Ford',
email: 'lorem@ipsum.com',
__v: 1 } },
_id: 5b1f061c91b4a7284b6d4945,
nameTeam: 'Real Madrid',
__v: 1 }
在这里粘贴了我的所有代码和预期输出后,我现在想要实现的是在我的前端(ejs文件)中展示了关于我的"团队"的一些基本信息:
查看文件
<thead>
<tr>
<th><i class="fa fa-image"></i></th>
<th><i class="fa fa-star"></i> Athlete</th>
<th class="hidden-phone"><i class="fa fa-question-circle"></i> Coach</th>
<th><i class="fa fa-bookmark"></i> Email</th>
<th></th>
</tr>
</thead>
<tbody>
<% teams.teamplayers.forEach(function(player) { %>
<tr>
<td></td>
<td><a href="basic_table.html#"><%= player.namePlayer %></a></td>
<td class="hidden-phone"><%= coach.coachName %></td>
<td><%= player.email %></td>
<td>
<form style="display: inline" action="/player/<%= player._id %>" method="GET">
<button class="btn btn-default btn-xs"><i class="fa fa-search-plus"></i></button>
</form>
</td>
</tr>
<% }); %>
</tbody>
使用最后一个代码(ejs视图)一切正常,直到我添加这一行:
<td class="hidden-phone"><%= coach.coachName %></td>
显然这是错的,我不知道如何填充&#34;教练姓名&#34;对于每个单独的运动员或团队而言,没有给出第二个forEach法则,这也不会起作用。
顺便说一句,我对这个问题反应很多,我找不到解决问题的最佳方法......看起来像 async function 是可能的,但老实说,我不确定。
可能解决方案比我想象的要容易,但是在13个小时后,我无法自己解决这个问题。
答案 0 :(得分:0)
coach
对象不存在。但是你有teamCoaches
,这是一个数组。不确定是否可以有多个教练,如果您应该调整逻辑以循环遍历teamCoaches
,就像循环teamPlayers
一样。
如果下面的代码总是一个教练应该工作:
<td class="hidden-phone"><%= teamCoaches[0].nameCoach %></td>
答案 1 :(得分:0)
您的对象是 currentTeam,您应该从那里获取对象属性,如下所示:
<tbody>
<% currentTeam.teamplayers.forEach(function(player) { %>
<tr>
<td></td>
<td><a href="basic_table.html#"><%= player.namePlayer %></a></td>
<td class="hidden-phone"><%= coach.coachName %></td>
<td><%= player.email %></td>
<td>
<form style="display: inline" action="/player/<%= player._id %>" method="GET">
<button class="btn btn-default btn-xs"><i class="fa fa-search-plus"></i></button>
</form>
</td>
</tr>
<% }); %>
</tbody>
在这一行 <td class="hidden-phone"><%= coach.coachName %></td>
请像这样编辑它:<td class="hidden-phone"><%= player.coachName %></td>
那应该没问题
