Get Started with Python SDK and Live Preview

This guide will help you get started with Contentstack Python SDK to build apps powered by Contentstack.

Pre-requisites

• Contentstack account
• Python version 3

Installation and Setup

To use the Contentstack Python SDK with your existing project, perform the following steps:

1. Open the terminal, create a project, and move inside it as follows:

   mkdir project_name
   cd project_name

2. Create a virtual environment:

   python3 -m venv venv

3. Activate the virtual environment:

   source venv/bin/activate

4. Install pip Contentstack as follows:

   pip install contentstack

You can download the latest dependency version here.

Initializing the Stack with Live Preview

Since the Live Preview Utils SDK is responsible for communication, you need to initialize it within your stack.

Use the following command to initialize the stack:

stack = contentstack.Stack('api_key', 'delivery_token', 'environment', live_preview= {
  'enable': True,
 'authorization': 'management_token',
 'host': 'api.contentstack.io',
});

Note: By default, the host parameter points to the North America endpoint. If your website is hosted on the European data center, then pass the European endpoint against the host parameter.

Create an Interceptor using Flask

Use the following code to create an interceptor using Flask:

from flask import request
from flask import Flask
app = Flask(__name__)

@app.before_request
def before_request():
   request_str = str(request.query_string)
   stack.live_preview_query(request_str)

For Server-side Rendered Websites

To install and initialize the Live Preview Utils SDK, you can refer to our SSR Live Preview Setup documentation.

Query Request

Contentstack SDKs let you interact with the Content Delivery APIs and retrieve content from Contentstack. They are read-only in nature. The SDKs fetch and deliver content from the nearest server via Fastly, our powerful and robust CDN.

To get an entry, you need to specify the content type UID and the UID of the entry.

entry = stack.content_type("content_type_uid").entry();
result = entry.fetch()
