Implementing PUT and PATCH user

To update the user, we need a page such as new_user(), but we want the form pre-populated with existing data. We also want to add another field for the user to confirm the old password. Let's look at the steps:

  1. Change the edit_user() function signature to the following:

    pub async fn edit_user(mut db: Connection<DBConnection>,    uuid: &str, flash: Option<FlashMessage<'_>>) -> HtmlResponse {}
  2. To get the existing user, append the following lines inside the function body block:
    let connection = db
        .acquire()
        .await
        .map_err(|_| Status::InternalServerError)?;
    let user = User::find(connection, uuid)
        .await
        .map_err(|_| Status::NotFound)?;
  3. After that, we can append the HTML, such as new_user(),...
