116 PointsFor SQLAlchemy, it is asking me to create a movie and add movie to session. Unsure what I'm doing wrong
Grateful for any help! :) The question is: Now you can create a movie to add to your database. Use a variable named new_movie. Create a Movie() with whatever movie_title and genre you want. Then add your movie to session.
My code is:
from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy.orm import sessionmaker
engine = create_engine(‘sqlite:///movies.db’, echo=False)
Session = sessionmaker(bind=engine)
session = Session()
Base = declarative_base()
class Movie(Base):
__tablename__ = ‘movies’
id = Column(Integer, primary_key=True)
movie_title = Column(String)
genre = Column(String)
if __name__ == "__main__":
Base.metadata.create_all(engine)
new_movie = Movie(movie_title = "Elf", genre = "Christmas")
session.add(new_movie)
My error is: Bummer: You should have a variable called new_movie that creates an instance of Movie(). Traceback (most recent call last): File "", line 16, in test_init_code AssertionError: Regex didn't match: 'new_movie\s*=\s*Movie\(\s*\r*\n*movie_title=\\'?\"?\’?[a-zA-Z0-9\s\-\\'\&\:\,\!]\\'?\"?\’?\s,\s*\r*\n*genre=\\'?\"?\’?[a-zA-Z\s\-\\']\\'?\"?\’?\s\r*\n*\)' not found in 'from sqlalchemy import create_engine, Column, Integer, String\nfrom sqlalchemy.ext.declarative import declarative_base\nfrom sqlalchemy.orm import sessionmaker\n\n\nengine = create_engine(‘sqlite:///movies.db’, echo=False)\nSession = sessionmaker(bind=engine)\nsession = Session()\nBase = declarative_base()\n\n\nclass Movie(Base):\n tablename = ‘movies’\n\n id = Column(Integer, primary_key=True)\n movie_title = Column(String)\n genre = Column(String)\n \nif name == "main":\n Base.metadata.create_all(engine)\n \n new_movie = Movie(movie_title = "Elf", genre = "Christmas")\n \n session.add(new_movie)' : You should have a variable called new_movie that creates an instance of Movie().

session.commit()
to the end of your code to make sure that SQLAlchmey recognises that you want to ad da table or add a record to it. :)

116 PointsI thought it might be that - it still doesn't work though. Very strange. Thanks for your help! :)
