commentBlog(req, res) {
const comment = {
comment: req.body.comment,
author: req.params.id
}
Comment.create(comment, (error, comment) => {
if (error) {
console.log(error);
} else {
Blog.findById(req.params.id, (error, blog) => {
blog.comments.push(comment);
console.log(comment);
blog.save((error, savedBlog) => {
if (error) {
console.log(error);
} else{
res.redirect('/blogs/' + blog._id);
}
})
})
}
})
};
(这是型号) -------------------- const mongoose = require('mongoose'), Schema = mongoose.Schema;
var commentSchema = new Schema({
author: { type: Schema.Types.ObjectId, ref: 'user' },
comment: {type: String},
created: {type: Date, default: Date.now},
blog: { type: Schema.Types.ObjectId, ref: 'blog' }
});
var Comment = mongoose.model('comment', commentSchema);
module.exports = Comment;
this is the ejs file
---------------------
<body>
<% if(blog) { %>
<form action="/blogs/<%= blog._id %>/comment" method="POST">
<textarea name="comment[text]"
rows="10" cols="50">Write something here
</textarea>
<input type="submit" value="Post comment">
</form>
<% } %>
**i don't know why it doesn't display when i add like to any post it just

好吧,您没有在ejs
文件中显示博客内容。只渲染表单。您应该呈现博客字段以供显示。下面是一个显示博客标题的示例(假设博客对象中有标题字段)。
<body>
<% if(blog) { %>
<h2><%= blog.title %> </h2>
<form action="/blogs/<%= blog._id %>/comment" method="POST">
<textarea name="comment[text]"
rows="10" cols="50">Write something here
</textarea>
<input type="submit" value="Post comment">
</form>
<% } %>
然后,您可以使用上面的示例显示博客对象中的其他字段。
