Polish Your Python Chops by Connecting Your App with WordPress

WordPress has develop into essentially the most used content material administration system (CMS) due in no small half to its utility programming interface (API). The WordPress REST API allows WordPress to “speak” with different purposes written in varied languages — together with Python.

Python is an extensible programming language with numerous makes use of and a human-readable syntax, making it a strong device for remotely managing WordPress content material.

Listed here are some WordPress REST API use circumstances to your apps and the way you need to use Python to assist them:

  • Use predefined templates to allow your app to show uncooked information into formatted posts with explanations rapidly.
  • Construct a back-office utility on Django and Python that shows limited-time provides to your clients each time an object-specific low cost or gross sales occasion happens.
  • Combine Python scripts to run inside your WordPress website

This tutorial will assist you to create a easy Python console utility that communicates with and executes operations on the WordPress REST API. The entire undertaking code can be out there.


Putting in and Configuring WordPress

First, let’s set up and run a WordPress web site domestically in your growth machine. This is a superb option to begin with WordPress because you don’t should create an account or purchase a site title for webhosting.

Earlier than putting in WordPress domestically, some parts are required to run in your pc, together with the Apache internet server, an area database, and the PHP language through which WordPress is written.

Luckily, we are able to use DevKinsta, a free native WordPress growth suite out there for all main OSes (you don’t should be a Kinsta buyer to make use of it).

DevKinsta is obtainable for Home windows, Mac, and Linux, and installs WordPress plus all of its dependencies in your native machine.

Earlier than putting in DevKinsta, it’s essential to have Docker operating domestically, so obtain and install the Docker Engine in case you haven’t but.

After putting in Docker Desktop, you possibly can automatically download the package deal that matches your OS.

DevKinsta set up web page.

Whenever you run the DevKinsta installer, Docker begins initializing instantly:

DevKinsta's starting Docker screen.
DevKinsta begins Docker domestically.

Subsequent, select New WordPress website from the Create new Web site menu:

DevKinsta's create new WordPress site screen.
DevKinsta’s Create New Web site menu.

Now the DevKinsta installer requires you to create the credentials for the WordPress admin account:

DevKinsta's new WordPress site creation screen.
DevKinsta displaying the New WordPress website type.

As soon as put in, DevKinsta is a standalone utility. Now you possibly can entry each the WordPress website (through the Open Web site button) and the WordPress admin dashboard (WP Admin button).

DevKinsta’s Web site information panel.

Subsequent, you could allow SSL and HTTPS to your web site. This improves the safety of your web site by means of an SSL certificates.

Enabling DevKinsta's SSL and HTTPS option.
DevKinsta’s “SSL and HTTPS” possibility.

Now go to the DevKinsta app and click on the Open website button. A brand new browser tab will present the house web page of your WordPress website:

The home page of your local WordPress site.
WordPress homepage.

That is your WordPress weblog, the place you can begin writing. However to allow Python to entry and use the WordPress REST API, we should first configure the WordPress Admin.

Now click on the WP Admin button on the DevKinsta app, then present your person and password to entry the WordPress Dashboard:

WordPress admin dashboard login screen.
WordPress login type.

When you’re logged in, you’ll see WordPress Dashboard:

Welcome to WordPress admin screen.
WordPress Dashboard web page.

WordPress makes use of cookie authentication as its normal technique. However if you wish to management it utilizing the REST API, it’s essential to authenticate with a way that grants entry to the WordPress REST API.

For this, you’ll use Application Passwords. These are 24-character lengthy strings that WordPress generates and associates with a person profile that has permission to handle your web site.

To make use of Software Passwords, click on the Plugin menu on the Dashboard, then seek for the plugin with the identical title. Then set up and activate the Software Passwords Plugin:

Installing and activating WordPress Application Passwords plugin.
Software Passwords plugin for WordPress.

To start creating your utility password, begin by increasing the Customers menu and clicking All Customers:

Expanded Users WordPress menu.
Expanded Customers menu.

Now, click on Edit beneath your admin person title:

Click the
WP-Admin WordPress interface.

Scroll down the Edit Consumer web page and discover the Software Passwords part. Right here, present a reputation for the Software Password, which you’ll use later to authenticate your Python app requests and devour the REST API:

Application Passwords plugin dashboard.
Software Password web page.

Click on Add New Software Password so WordPress can generate a random 24-character  password for you:

The new password generated by Application Passwords plugin.
New Software Password web page.

Subsequent, copy this password and reserve it in a protected location to make use of later. Bear in mind, you received’t be capable of retrieve this password when you shut this web page.

Lastly, it’s essential to configure permalinks. WordPress lets you create a customized URL construction to your permalinks and archives. Let’s change it so {that a} WordPress submit titled, e.g., “Your First WordPress Web site” may be accessed by means of the intuitive URL https://your-website.native:port/your-first-wordpress-website/. This method brings a number of advantages, together with improved usability and aesthetics.

To configure permalinks, develop the Settings part and click on the Permalinks menu. Right here, change the Frequent Settings to Submit title:

Changing WordPress permalink settings.

Setting the permalink construction utilizing the Submit title construction can be obligatory as a result of it’ll enable us to retrieve posts later in our Python code utilizing the JSON format. In any other case, a JSON decoding error will likely be thrown.

How To Management WordPress From Python

WordPress is written in PHP, however it has a REST API that allows different programming languages, websites, and apps to devour its content material. Exposing the WordPress content material in REST structure makes it out there in JSON format. Due to this fact, different companies can combine with WordPress and carry out create, learn, replace and delete (CRUD) operations with out requiring an area WordPress set up.

Subsequent, you’ll construct a easy Python app to see how you need to use the WordPress REST API to create, retrieve, replace, and delete posts.

Create a brand new listing to your new easy Python undertaking and title it one thing like PythonWordPress:

../PythonWordPress

Now, you’ll create a digital setting to your undertaking, permitting it to keep up an unbiased set of put in Python packages, isolating them out of your system directories and avoiding model conflicts. Create a digital setting by executing the venv command:

python3 -m venv .venv

Now, run a command to activate the .venv digital setting. This command varies by OS:

  • Home windows: .venvScriptsactivate
  • Mac/Linux: .venv/bin/activate

Subsequent, retailer the configuration associated to your WordPress account. To separate the app configuration out of your Python code, create a .env file in your undertaking listing, and add these setting variables to the file:

WEBSITE_URL="<>"

API_USERNAME="<>"

API_PASSWORD="<>"

Luckily, studying the info above from a Python app is straightforward. You’ll be able to set up the Python-dotenv package deal so your utility can learn configuration from the .env file:

pip set up python-dotenv

Then, set up aiohttp, an asynchronous HTTP shopper/server for Python:

pip set up aiohttp

Now add a file named app.py with the next code:

import asyncio

menu_options = {

1: 'Checklist Posts',

2: 'Retrieve a Submit'

}

def print_menu():

for key in menu_options.keys():

print (key, '--', menu_options[key] )

async def principal():

whereas(True):

print_menu()

possibility = input_number('Enter your alternative: ')

#Verify what alternative was entered and act accordingly

if possibility == 1:

print('Itemizing posts...')

elif possibility == 2:

print('Retrieving a submit...')

else:

print('Invalid possibility. Please enter a quantity between 1 and 5.')

def input_number(immediate):

whereas True:

attempt:

worth = int(enter(immediate))

besides ValueError:

print('Unsuitable enter. Please enter a quantity ...')

proceed

if worth < 0:

print("Sorry, your response should not be destructive.")

else:

break

return worth

def input_text(immediate):

whereas True:

textual content = enter(immediate)

if len(textual content) == 0:

print("Textual content is required.")

proceed

else:

break

return textual content

if __name__=='__main__':

asyncio.run(principal())

The code above shows a console menu and asks you to enter a quantity to decide on an possibility. Subsequent, you’ll develop this undertaking and implement the code that allows you to listing all posts and retrieve a particular submit utilizing its submit id.

Fetching Posts in Code

To work together with WordPress REST API, it’s essential to create a brand new Python file. Create a file named wordpress_api_helper.py with the next content material:

import aiohttp

import base64

import os

import json

from dotenv import load_dotenv

load_dotenv()

person=os.getenv("API_USERNAME")

password=os.getenv("API_PASSWORD")

async def get_all_posts():

async with aiohttp.ClientSession(os.getenv("WEBSITE_URL")) as session:

async with session.get("/wp-json/wp/v2/posts") as response:

print("Standing:", response.standing)

textual content = await response.textual content()

wp_posts = json.hundreds(textual content)

sorted_wp_posts = sorted(wp_posts, key=lambda p: p['id'])

print("=====================================")

for wp_post in sorted_wp_posts:

print("id:", wp_post['id'])

print("title:", wp_post['title']['rendered'])

print("=====================================")

async def get_post(id):

async with aiohttp.ClientSession(os.getenv("WEBSITE_URL")) as session:

async with session.get(f"/wp-json/wp/v2/posts/{id}") as response:

print("Standing:", response.standing)

textual content = await response.textual content()

wp_post = json.hundreds(textual content)

print("=====================================")

print("Submit")

print("     id:", wp_post['id'])

print("     title:", wp_post['title']['rendered'])

print("     content material:", wp_post['content']['rendered'])

print("=====================================")

Discover the usage of the aiohttp library above. Trendy languages present syntax and instruments that allow asynchronous programming. This will increase the applying responsiveness by permitting this system to carry out duties alongside operations like web requests, database operations, and disk I/O. Python provides asyncio as a basis for its asynchronous programming framework, and the aiohttp library is constructed on prime of asyncio to deliver asynchronous entry to HTTP Consumer/Server operations made in Python.

The ClientSession perform above runs asynchronously and returns a session object, which our program makes use of to carry out an HTTP GET operation in opposition to the /wp-json/wp/v2/posts endpoint. The one distinction between a request to retrieve all posts and a request for a particular one is that this final request passes a submit id parameter within the URL route: /wp-json/wp/v2/posts/{id}.

Now, open the app.py file and add the import assertion:

from wordpress_api_helper import get_all_posts, get_post

Subsequent, modify the principal perform to name the get_all_posts and get_post features:

if possibility == 1:

print('Itemizing posts...')

await get_all_posts()

elif possibility == 2:

print('Retrieving a submit...')

id = input_number('Enter the submit id: ')

await get_post(id)

Then run the app:

python app.py

You’ll then see the applying menu:

Starting the Python app connected to WordPress.
Python utility menu.

Now attempt possibility 1 to view the listing of posts that your Python app retrieves, and possibility 2 to pick out a submit:

Try option 1 to view the list of posts that your Python app retrieves, and option 2 to select a post.
Python app exhibiting the posts listing and a single user-selected submit.

Creating Posts in Code

To create a WordPress submit in Python, start by opening the wordpress_api_helper.py file and add the create_post perform:

async def create_post(title, content material):

async with aiohttp.ClientSession(os.getenv("WEBSITE_URL")) as session:

async with session.submit(

f"/wp-json/wp/v2/posts?content material={content material}&title={title}&standing=publish"

, auth=aiohttp.BasicAuth(person, password)) as response:

print("Standing:", response.standing)

textual content = await response.textual content()

wp_post = json.hundreds(textual content)

post_id = wp_post['id']

print(f'New submit created with id: {post_id}')

This code calls the submit perform within the session object, passing the auth parameter beside the REST API endpoint URL. The auth object now comprises the WordPress person and the password you created utilizing Software Passwords. Now, open the app.py file and add code to import create_post and the menu:

from wordpress_api_helper import get_all_posts, get_post, create_post

menu_options = {

1: 'Checklist Posts',

2: 'Retrieve a Submit',

3: 'Create a Submit'

}

Then add a 3rd menu possibility:

elif possibility == 3:

print('Making a submit...')

title = input_text('Enter the submit title: ')

content material = input_text('Enter the submit content material: ')

await create_post(title, f"{content material}")

Then, run the app and check out possibility 3, passing a title and content material to create a brand new submit in WordPress:

Creating a WordPress post with Python.
Python app displaying newly created WordPress submit.

Selecting possibility 1 once more will return the id and the title of the newly added submit:

Returning the id and the title of the newly added post.
Python app returning the brand new submit’s title and id.

You can too open your WordPress web site to view the brand new submit:

The newly created post in the browser.
Browser picture of the brand new WordPress submit.

Updating Posts in Code

Open the wordpress_api_helper.py file and add the update_post perform:

async def update_post(id, title, content material):

async with aiohttp.ClientSession(os.getenv("WEBSITE_URL")) as session:

async with session.submit(

f"/wp-json/wp/v2/posts/{id}?content material={content material}&title={title}&standing=publish"

, auth=aiohttp.BasicAuth(person, password)) as response:

print("Standing:", response.standing)

textual content = await response.textual content()

wp_post = json.hundreds(textual content)

post_id = wp_post['id']

print(f'New submit created with id: {post_id}')

Then open the app.py file and add code to import update_post and the menu:

from wordpress_api_helper import get_all_posts, get_post, create_post, update_post

menu_options = {

1: 'Checklist Posts',

2: 'Retrieve a Submit',

3: 'Create a Submit',

4: 'Replace a Submit'

}

Then, add a fourth menu possibility:

elif possibility == 4:

print('Updating a submit...')

id = input_number('Enter the submit id: ')

title = input_text('Enter the submit title: ')

content material = input_text('Enter the submit content material: ')

await update_post(id, title, f"{content material}")

Then run the app and check out possibility 4, passing a submit id, title, and content material to replace an current submit.

Python app exhibiting the up to date menu.

Selecting possibility 2 and passing the up to date submit id will return the main points of the newly added submit:

Returning the details of the newly updated post.
Python app exhibiting the up to date submit.

Deleting Posts in Code

You’ll be able to go the submit id to the REST API to delete a submit.

Open the wordpress_api_helper.py file and add the delete_post perform:

async def delete_post(id):

async with aiohttp.ClientSession(os.getenv("WEBSITE_URL")) as session:

async with session.delete(

f"/wp-json/wp/v2/posts/{id}"

, auth=aiohttp.BasicAuth(person, password)) as response:

print("Standing:", response.standing)

textual content = await response.textual content()

wp_post = json.hundreds(textual content)

post_id = wp_post['id']

print(f'Submit with id {post_id} deleted efficiently.')

Now open the app.py file and add code to import delete_post and the menu:

from wordpress_api_helper import get_all_posts, get_post, create_post, update_post, delete_post

menu_options = {

1: 'Checklist Posts',

2: 'Retrieve a Submit',

3: 'Create a Submit',

4: 'Replace a Submit',

5: 'Delete a Submit',

}

Then, add a fifth menu possibility:

elif possibility == 5:

print('Deleting a submit...')

id = input_number('Enter the submit id: ')

await delete_post(id)

Now run the app and check out possibility 5, passing an id to delete the present submit in WordPress:

Deleting a WordPress post with the Python app.
Python app exhibiting deletion of the chosen submit.

Notice: The deleted submit should seem in case you run the Checklist Posts possibility:

Python app listing posts.
Python app exhibiting unique submit listing.

To substantiate that you just’ve deleted the submit, wait a number of seconds and check out the Checklist Posts possibility once more. And that’s it!
