我正尝试在博客文章中发布评论,并将这些评论作为每个帖子的数组。
我设法将评论发布,但是我无法从帖子中调用信息。注释模型中包含文本和作者,但注释仅包含模型的作者部分。当评论显示在帖子上时,它们仅显示撰写评论的用户名。我已经检查了数据库,并且comment.text根本没有通过。
评论创建路线
router.post("/", ensureAuthenticated, (req, res) => {
Blog.findById(req.params.id, (err, blog) => {
if(err){
console.log(err);
res.redirect("/blog");
} else {
Comment.create(req.body.comment, (err, comment) => {
if(err){
req.flash("error", "Something went wrong");
console.log(err);
} else {
//add username and id to comment
comment.author.id = req.user._id;
comment.author.name = req.user.name;
comment.author.email = req.user.email;
comment.save();
//save comment
blog.comments.push(comment);
blog.save();
req.flash("success", "Successfully added comment");
res.redirect("/blog/" + blog._id);
}
});
}
});
});
评论模式
const mongoose = require("mongoose");
var commentSchema = new mongoose.Schema({
text: String,
author: {
id: {
type: mongoose.Schema.Types.ObjectId,
ref: "User"
},
name: String,
email: String
}
});
module.exports = mongoose.model("Comment", commentSchema);
显示评论的部分显示页面
<div class="card-body">
<% blog.comments.forEach(function(comment){ %>
<div class="row">
<div class="col-md-12">
<strong><%= comment.author.name %></strong>
<span class="float-right">10 days ago</span>
<p class="card-text">
<%= comment.text %>
</p>
<% if(user && comment.author.id.equals(user._id)) { %>
<a class="btn btn-warning btn-sm d-inline-block" href="/blog/<%= blog._id %>/comments/<%= comment._id%>/edit">Edit</a>
<form class="d-inline-block" action="/blog/<%= blog._id %>/comments/<%= comment._id%>?_method=DELETE" method="POST">
<button class="btn btn-danger btn-sm">Delete</button>
</form>
<% } %>
<hr>
</div>
</div>
<% }) %>
</div>
我希望显示页面显示每个评论的文本。
