Lecture 354:- Showing the Avatar, Connecting the Dot

I assume that "Connecting the Dot" here means to connect the uploaded avatar image to the user's account/profile. To do this, we need to update the user's document in the database with the file path of the uploaded avatar image.

Here are the general steps to connect the uploaded avatar image to the user's account/profile:

1. Update the user's schema to include a new field for storing the avatar image file path. For example:

arduinoCopy code

const userSchema = new mongoose.Schema({  // existing fields  avatar: {    type: String  } });

1. When a user uploads an avatar image, save the file to a directory on the server using Multer.
2. After the file has been saved, get its file path and update the user's document in the database with the file path. You can do this by finding the user by their ID and then using the updateOne method to set the avatar field to the file path. For example:

csharpCopy code

router.post('/upload-avatar', upload.single('avatar'), async (req, res) => {  // Get the file path of the uploaded avatar image  const avatarPath = req.file.path;  // Update the user's document with the file path  const userId = req.user._id;  await User.updateOne({ _id: userId }, { avatar: avatarPath });  // Redirect to the user's profile page  res.redirect('/profile'); });

1. In the user's profile page, display the avatar image using the file path stored in the avatar field of the user's document. For example:

phpCopy code

<img src="{{ user.avatar }}" alt="Avatar">

Note that you need to pass the user object (which includes the avatar field) to the view when rendering the user's profile page.
