Solve the following python programming problem given the following code:
def create_app(config = None, debug = True) : 
    app = create_base_app (before_first_request, debug) 
    app.config ['DATABASE'] = { 
        'name' : 'example2.db', 
        'engine' : 'peewee.SqliteDatabase', 
} 
    db = Database (app) 
    class Role (db.Model, RoleMixin) : 
        name = TextField (unique = True) 
        description = TextField (null = True) 
class User (db.Model, UserMixin) : 
        email = TextField () 
        password = TextField () 
        last_login_at = DateTimeField (null = True) 
        current_login_at = DateTimeField (null = True) 
        last_login_ip = TextField (null = True) 
        current_login_ip = TextField (null = True) 
        login_count = IntegerField (null = True) 
        active = BooleanField (default = True) 
        confirmed_at = DateTimeField (null = True) 
class UserRoles (db.Model) : 
        ' Peewee does not have built-in many-to-many support, so we have to
        create this mapping class to link users to roles.' 
        user = ForeignKeyField (User, related_name = 'roles') 
        role = ForeignKeyField (Role, related_name = 'users') 
        name = property ((lambda self : self.role.name)) 
        description = property ((lambda self : self.role.description)) 
class Connection (db.Model) : 
        user = ForeignKeyField (User, related_name = 'connections') 
        provider_id = TextField () 
        provider_user_id = TextField () 
        access_token = TextField () 
        secret = TextField (null = True) 
        display_name = TextField () 
        full_name = TextField () 
        profile_url = TextField () 
        image_url = TextField () 
        rank = IntegerField (null = True) 
app.security = Security (app, PeeweeUserDatastore (db, User, Role, UserRoles)) 
    app.social = Social (app, PeeweeConnectionDatastore (db, Connection)) 
    @ app.before_first_request 
    def before_first_request() : 
        for Model in (Role, User, UserRoles, Connection) : 
            Model.drop_table (fail_silently = True) 
           ...

    
    

    Fix the buggy line: app = create_base_app (before_first_request, debug)
assistant
#Here is Python code to fix the buggy line: app = create_base_app (before_first_request, debug)
.

app = create_base_app (config, debug)
