发送好友请求时出错

我正在做一个Facebook克隆,在过去的几天里,我一直在努力想出发送朋友请求的逻辑。

这是我的FriendRequest架构。

const friendRequestSchema = new mongoose.Schema({
  sender: {
    type: mongoose.Schema.Types.ObjectId,
    ref: "User",
    required: true,
  },
  receiver: {
    type: mongoose.Schema.Types.ObjectId,
    ref: "User",
    required: true,
  },
  status: {
    type: String,
    enum: ["pending", "accepted", "rejected"],
    default: "pending",
  },
  createdAt: {
    type: Date,
    default: Date.now,
  },
});

这是我的发送好友请求按钮。输入被隐藏,因此只有按钮显示。

<form action="/friend-requests" method="POST">
  <input type="hidden" name="sender" value="<%= id %>" />
  <input type="hidden" name="receiver" value="<%= user._id %>" />
  <button type="submit">Send Friend Request</button>
</form>

这是我发送好友请求的逻辑。

// POST route to handle the friend request submission
router.post("/friend-requests", (req, res) => {
  const { sender, receiver } = req.body;

  // Create a new FriendRequest instance
  const newRequest = new FriendRequest({
    sender,
    receiver,
  });

  // Save the friend request to the database
  newRequest
    .save()
    .then(() => {
      // Redirect to a success page or send a response indicating success
      res.send("Friend request sent successfully!");
    })
    .catch((error) => {
      // Handle the error appropriately
      res.status(500).send("Error sending friend request");
    });
});

我想做什么

当用户选择 "Send Friend Request" 在用户配置文件页面上的按钮,一个请求通过并将用户添加到 pending 要求当上述用户检查他们的好友请求时,它会列出所有挂起的请求,他们可以接受也可以拒绝。这是非常基本的东西,但在过去几天里,我梳理了几十个线程后,很难将其全部设置好。

更新-更多代码

这是我的GET user 个人资料页。它会在您的页面上列出您自己的所有状态更新。

router.get("/:user", function (req, res, next) {
  Status.find({}, "content author createdAt")
    .sort({ title: 1 })
    .exec(function (err, list_status) {
      if (err) {
        return next(err);
      }
      res.render("profile", {
        status_list: list_status,
        id: id,
      });
    });
});

此代码发布来自 index 页面。

router.post("/:user", [
  // Validate and sanitize fields.
  body("content", "Content must not be empty.")
    .trim()
    .isLength({ min: 1 })
    .escape(),
  // Process request after validation and sanitization.
  (req, res, next) => {
    const errors = validationResult(req);

    const status = new Status({
      content: req.body.content,
      author: req.body.author,
    });

    if (!errors.isEmpty()) {
      async.parallel((err, results) => {
        if (err) {
          return next(err);
        }
        res.render("profile", {
          content: content,
          author: author,
          status,
          errors: errors.array(),
        });
      });
      return;
    }
    status.save((err) => {
      if (err) {
        return next(err);
      }
      res.redirect("/");
    });
  },
]);

我的用户架构

const userSchema = new mongoose.Schema({
  firstname: String,
  lastname: String,
  username: {
    type: String,
    unique: true,
    required: [true, "can't be blank"],
    match: [/^[a-zA-Z0-9]+$/, "is invalid"],
    index: true,
  },
  email: {
    type: String,
    lowercase: true,
    unique: true,
    required: [true, "can't be blank"],
    match: [/\S+@\S+\.\S+/, "is invalid"],
    index: true,
  },
  password: String,
  email: String,
  createdAt: { type: Date, default: Date.now },
  friends: [
    {
      type: mongoose.Schema.Types.ObjectId,
      ref: "User",
    },
  ],
});
