Bummer! cannot import name 'HASHER'

I'm having trouble with this and kinda confused plus I keep getting the error

Bummer! cannot import name 'HASHER' import datetime

from peewee import * import hashlib

DATABASE = SqliteDatabase('recipes.db')

class User(Model): username = CharField(unique=True) password = CharField()

class Meta:
    database = DATABASE

@classmethod
def create_user(cls, username, password):
    try:
        cls.get(cls.username**username)
    except cls.DoesNotExist:
        user = cls(username=username)
        password = 'pa$$w0rd'
        h = hashlib.md5(password.encode)
        user.save()
        return user
    else:
        raise Exception("User already exists")

class Recipe(Model): name = CharField() created_at = DateTimeField(default=datetime.datetime.now)

class Meta:
    database = DATABASE

class Ingredient(Model): name = CharField() description = CharField() quantity = DecimalField() measurement_type = CharField() recipe = ForeignKeyField(Recipe)

class Meta:
    database = DATABASE

def initialize(): DATABASE.connect() DATABASE.create_tables([User, Recipe, Ingredient], safe=True) DATABASE.close()

@staticmethod def hash_password(password): return HASHER.hash(password)

Should pass the 2nd part watch you indentation. Also if you go a video ahead and load the workspace alot of times theres pretty much an example of the code they ask you to write; get use to lookin at the documentation on the web to. But yeah bangin my head on the desk alot with these.

GoodLuck.

@Jeff Bender Hey man check this code out and let me know what I am doing wrong it tells me that I need to name it user.hash_password but not sure where I need to put the name I had tried in both of the classes and now it tells me no longer passing and its the second part of the first question you helped me on

@classmethod def create_user(cls, username, password): try: cls.get(cls.username**username) except cls.DoesNotExist: user = cls(username=username) user= cls(user.hash_password) user.save() return user else: raise Exception("User already exists")

@staticmethod
def set_password(password):
    return HASHER.hash(password)
def verify_password(user, password)
    return HASHER.verify(user.password, password)
