AttributeError: type object 'User' has no attribute 'create_user'

You have a formatting error. In your User class, all thing attributed to that class need to be indented. your class method create_user is not indented under the User class and is not being counted as part of that class. e.g.

class User(UserMixin, Model):
    username = CharField(unique=True)
    email = CharField(unique=True)
    password = CharField(max_length=100)
    joined_at = DateTimeField(default=datetime.datetime.now)
    is_admin = BooleanField(default=False)

# Everything below this line is not being counted as part of the User class

class Meta: 
    database = DATABASE
    order_by = ('-joined_at',)

def get_posts(self):
    return Post.select().where(Post.user == self)

def get_stream(self):
    return Post.select().where(
        (Post.user == self)
    )

@classmethod
def create_user(cls, username, email, password, admin=False):
    try:
        with DATABASE.transaction():
            cls.create(
                username=username,
                email=email,
                password=generate_password_hash(password),
                is_admin=admin)
    except IntegrityError:
        raise ValueError("User already exists")

class User(UserMixin, Model):
    username = CharField(unique=True)
    email = CharField(unique=True)
    password = CharField(max_length=100)
    joined_at = DateTimeField(default=datetime.datetime.now)
    is_admin = BooleanField(default=False)

    # everything below this line is now part of the User  class
    class Meta:
        database = DATABASE
        order_by = ('-joined_at',)

    def get_posts(self):
        return Post.select().where(Post.user == self)

    def get_stream(self):
        return Post.select().where(
            (Post.user == self)
        )

    @classmethod
    def create_user(cls, username, email, password, admin=False):
        try:
            with DATABASE.transaction():
                cls.create(
                    username=username,
                    email=email,
                    password=generate_password_hash(password),
                    is_admin=admin)
        except IntegrityError:
            raise ValueError("User already exists")

You probably have a typo in you create_user method in your model. Can you post your code?

Thank you for replying Seth, I appreciate the help. Here is my models.py file:

import datetime

from flask.ext.bcrypt import generate_password_hash from flask.ext.login import UserMixin from peewee import *

DATABASE = SqliteDatabase('social.db')

class User(UserMixin, Model): username = CharField(unique=True) email = CharField(unique=True) password = CharField(max_length=100) joined_at = DateTimeField(default=datetime.datetime.now) is_admin = BooleanField(default=False)

class Meta: database = DATABASE order_by = ('-joined_at',)

def get_posts(self): return Post.select().where(Post.user == self)

def get_stream(self): return Post.select().where( (Post.user == self) )

@classmethod def create_user(cls, username, email, password, admin=False): try: with DATABASE.transaction(): cls.create( username=username, email=email, password=generate_password_hash(password), is_admin=admin) except IntegrityError: raise ValueError("User already exists")

class Post(Model): timestamp = DateTimeField(default=datetime.datetime.now) user = ForeignKeyField( rel_model=User, related_name='posts' ) content = TextField()

class Meta: database = DATABASE order_by = ('-timestamp',)

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

and just incase, here is my app.py file:

Thank you again!

Help Please?

@Seth Reece I pushed it to my github account, and since i've been getting the error it won't pop up on my browser when i got to "localhost:8000", and i am unable to get the full log. and thank you for catching that typo, i went ahead and changed it. here is the repo, https://github.com/GabeRivera/python_project

Seth Reece Thank you so much, I indented it as you showed me and i stopped getting the error. Unfortunately I am still unable to get this working. Now when i try to run "python app.py" i get the following message: File "app.py", line 118, in <module> models.initialize() AttributeError: 'module' object has no attribute 'initialize'

When i checked the app.py file, i noticed that i also made an indentation error.

@app.route('/stream') @app.route('/stream/<username>') def stream(username=None): template = 'stream.html' if username and username != current_user.username: user = models.User.select().where(models.User.username**username).get() stream = user.post.limit(100) else: stream = current_user.get_stream().limit(100) user = current_user if username: template = 'user_stream.html' return render_template(template, stream=stream, user=user)

if name == 'main': models.initialize() try: models.User.create_user( username='GabeRivera', email='gabriel.f.rivera.10@gmail.com', password='turbo13negro', admin=True ) except ValueError: pass app.run(debug=DEBUG, host=HOST, port=PORT)

So i indented the if_name=='main_': section. and now it looks like so:

@app.route('/stream') @app.route('/stream/<username>') def stream(username=None): template = 'stream.html' if username and username != current_user.username: user = models.User.select().where(models.User.username**username).get() stream = user.post.limit(100) else: stream = current_user.get_stream().limit(100) user = current_user if username: template = 'user_stream.html' return render_template(template, stream=stream, user=user)

if __name__ == '__main__':
    models.initialize()
    try:
        models.User.create_user(
            username='GabeRivera',
            email='gabriel.f.rivera.10@gmail.com',
            password='turbo13negro',
            admin=True
        )
    except ValueError:
        pass
    app.run(debug=DEBUG, host=HOST, port=PORT)

but now anytime i try to run it on the console. "python app.py", i does nothing and just deletes what i typed. Now Im really lost haha, thank you for the help.
