EJS / Mongoose-帖子倾向于在发布后两次显示，当我尝试获得同一页面时，它显示了两次

基本上是我发布创建邮政控制器时，帖子一次显示，问题是当我获得同一页面时，它显示了两次？

我该如何解决此问题，以便如果帖子已经存在，那么即使我得到页面也不应该显示另一个时间？

我的目标是在用户帖子或获取页面上，它仍然应该显示一次。

管理员控制器

const path = require('path');
const bcrypt = require("bcryptjs");
const mongoose = require("mongoose");
const _ = require("lodash");
const {
    User,
    Post,
} = require("../models/model");
exports.getMyPostsPage = (req, res) => {
    res.render("admin/myposts", {
        path: "/myposts",
        pageTitle: "My Posts",
    })
}
exports.getCreatepostPage = (req, res) => {
    res.render("admin/createpost", {
        path: "/create",
        pageTitle: "Create",
    });
}

exports.getPostsPage = async (req, res) => {
    try {
        const posts = await Post.find({})
        res.render("admin/posts", {
            path: "/posts",
            pageTitle: "Posts",
            posts: posts
        });
    } catch (err) {
        console.log(err);
    }

}
exports.postCreatePost = async (req, res) => {
    const {
        title,
        description,
        context
    } = req.body;
    const post = new Post({
        title,
        description,
        context,
        author: req.user
    });
    try {
        const savedPost = await post.save()
        const usersPost = await req.user.posts.push(post);
        console.log(req.user.posts)
        const posts = await Post.find({})
        res.render("admin/posts", {
            pageTitle: "Posts",
            path: "/posts",
            posts: posts
        })
    } catch (err) {
        console.log(err);
    }
}

posts.ejs

<%- include("../includes/head.ejs") %>
<link rel="stylesheet" href="/css/admin.css">
</head>
<body>
    <%- include("../includes/navigation.ejs", ) %>
    <% for (const post of posts) { %>
    <div class="posts">
        <form action="/post" method="POST">
            <h1><%=post.title%></h1>
            <p><%=post.description%></p>
            <input type="hidden" name="_csrf" value="<%= csrfToken %>">
            <button type="submit">
                See Post
            </button>

        </form>
    </div>
    <% } %>
    <%- include("../includes/footer.ejs") %>

const mongoose = require("mongoose"),
    Schema = mongoose.Schema,
    bcrypt = require("bcryptjs");


const postSchema = new Schema({
    title: String,
    description: String,
    context: String,
    author: {
        type: Schema.Types.ObjectId,
    }
});

const userSchema = new Schema({
    name: {
        type: String,
        required: true
    },
    email: {
        type: String,
        required: true,
    },
    password: {
        type: String,
        required: true
    },
    posts: [postSchema]
});

userSchema.pre("save", async function save(next) {
    const user = this;
    if (!user.isModified("password")) return next();
    const hashedPassword = await bcrypt.hash(user.password, 10);
    user.password = hashedPassword;
    next();
});

const Post = mongoose.model("Post", postSchema);
const User = mongoose.model("User", userSchema);
module.exports = {
    User,
    Post
}

我在使用F5按钮时遇到了问题，它重复了帖子部分，但是现在很好，实际上这不是一个真正的问题，只是一个错误。
