💡 Hint

Common Mistakes

Using Integer or Boolean types for password hash

Using Text which allows unlimited length but is less common here

The password hash is stored as a string with a max length, so String is the correct column type.

3fill in blank

hard

Fix the error in the method that sets the password hash.

Flask

def set_password(self, password):
    self.password_hash = [1](password)

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using check_password_hash instead of generate_password_hash

Trying to assign the password string directly

The generate_password_hash function creates a secure hash from the password string.

4fill in blank

hard

Fill both blanks to complete the method that verifies a password.

Flask

def check_password(self, password):
    return [1](self.password_hash, [2])

Drag options to blanks, or click blank then click option'

Acheck_password_hash

Bpassword

Cgenerate_password_hash

Dself.password

💡 Hint

Common Mistakes

Swapping the order of arguments

Using generate_password_hash instead of check_password_hash

The check_password_hash function compares the stored hash with the given password string.

5fill in blank

hard

Fill all three blanks to complete the User model with password methods.

Flask

class User(db.Model):
    id = db.Column(db.Integer, primary_key=True)
    username = db.Column(db.String(64), unique=True, nullable=False)
    password_hash = db.Column(db.String(128), nullable=False)

    def set_password(self, password):
        self.password_hash = [1](password)

    def check_password(self, password):
        return [2](self.password_hash, [3])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Mixing up generate_password_hash and check_password_hash

Passing the wrong argument to check_password_hash

The set_password method uses generate_password_hash to create the hash. The check_password method uses check_password_hash to verify the password against the stored hash.
