Overview

In the following article, I described how to create new content.

Adding Content to Drupal Using Python

This time, I'll try updating and deleting existing content.

Filtering Items

With the following program, you can retrieve registered content. This time, I retrieved content with the title "Pre-update title." res["data"] is an array.

username = "xxx"
password = "xxx"
host = "xxx"

query = {
    "title": "更新前のタイトル"
}

item_type = "article"

filters = []

for key, value in query.items():
    filters.append(f'filter[{key}]={value}')

filter_str = '&'.join(filters)

endpoint = f'{host}/jsonapi/node/{item_type}?{filter_str}'

r = requests.get(endpoint, headers=headers, auth=(username, password))

res = r.json()

len(res['data'])

Getting the ID of the Content to Update

An ID like 730f844d-b476-4485-8957-c33fccb7f8ac is obtained.

item = res['data'][0]
item_id = item['id']

Updating

Specify the type and id to update.

payload = {
    "data": {
        "type": f"node--{item_type}",
        "id": item_id,
        "attributes": {
            "title": "更新後のタイトル"
        }
    }
}

url = f"{host}/jsonapi/node/{item_type}/{item_id}"
r = requests.patch(url, headers=headers, auth=(username, password), json=payload)

r.json()

Deleting

Deletion can be executed as follows.

requests.delete(url, auth=(username, password))

Summary

I hope this serves as a useful reference when editing content on Drupal programmatically.
