Creating the House and HouseChecker Models

Creating the House and HouseChecker Models

Learn how to create models in Flask.

We'll cover the following...

Creating the House model

In our Core app, the House model will have the following attributes:

  • A name for identification of each house.

  • An image data of each house for visual recognition.

  • A description of each house.

First, we'll import the dataclass from dataclasses, like so:

from dataclasses import dataclass

Then, we can create our House model inside the core.py file, as shown below:

Press + to interact
@dataclass
class House(db.Model):
    id: int
    name: str
    image: str
    description: str
    id = db.Column(db.Integer, primary_key=True, autoincrement=False)
    name = db.Column(db.String(150))
    image = db.Column(db.String(150))
    description = db.Column(db.String(150))

  • Line 1: We instantiate the dataclass with @dataclass. This decorator enforces data validation and makes the data types in this model easily serializable. ...
