How to create REST API using Pyramid

Pyramid is a lightweight python web framework following MVC architectural pattern. In this article, we will set up a web application and API using Pyramid.

Pyramid is a suitable framework for large scale MVC applications and it comes with flexible bootstrapping tools.

Cornice, a library from Mozilla, makes it easy to develop RESTful web services with pyramid.

Installation

First we create a virtual environment which helps us in separating project specific python packages installations from other projects. After activating the virtual environment, we install pyramid framework using command:

pip install pyramid

Create models

We create a models.py file with a class Note which maps to the data table storing all the values of notes.

# pyramidapp/models.py
class Note(Base):
    __tablename__ = 'Note'
    id = Column(Integer, primary_key=True)
    title = Column(Text)
    description = Column(Text)
    create_at = Column(Text)
    create_by = Column(Text)
    priority = Column(Integer)
    def __init__(self, title, description, create_at ,create_by, priority):
        self.title = title
        self.description = description
        self.create_at = create_at
        self.create_by = create_by
        self.priority = priority
    @classmethod
    def from_json(cls, data):
        return cls(**data)
    def to_json(self):
        to_serialize = ['id', 'title', 'description', 'create_at', 'create_by', 'priority']
        d = {}
        for attr_name in to_serialize:
            d[attr_name] = getattr(self, attr_name)
        return d
