Finally, your table needs some columns. Add Column, Integer, and String to your sqlalchemy imports. Create an id column

I'm a little confused about what they are telling me to do...

models.py 
# insert your code here
from sqlalchemy import create_engine, Column, Integer, String
from sqlalchemy.ext.declarative import declarative_base

engine = create_engine('sqlite:///movies.db', echo=False)
Base = declarative_base()

class Movie(Base):
    __tablename__ = 'movies'

Hi Javi! In this challenge, you're creating a database (movies.db) with a table called "Movie."

This task is asking you to include specific columns in your table.

You need:

  • an id column that holds numbers and is a primary key.
  • a column called movie_title that holds strings.
  • a column called genre that holds strings

Let me show you my code from another project, and what it is doing:

class Product(Base):
    __tablename__ = "products"
    product_id = Column(Integer, primary_key=True)
# creates a product_id column. It holds an integer, and it will act as a primary key ID for each item added to the database.
    product_name = Column("Product Name", String)
# creates a product_name column. All data in this column must be strings.)
# Note: you don't HAVE to include "Product Name" in the parentheses after Column. 
# All "Product Name" does is format the title of the column when you open the database in a program like DB Browser for SQLite.
    product_price = Column("Product Price", Integer)
# creates a product_price column. All data in this column must be integers.
    product_quantity = Column("Product Quantity", Integer)
# creates a product_quantity column. All data in this column must be integers.
    date_updated = Column("Date Updated", DateTime)
#creates a date_updated column. All data in this column must be DateTime objects.

I hope this is helpful! Let me know if you have more questions!
