Help needed with Notion API and related tables

I’m struggling to fetch data from linked columns in my Notion databases. When I try to access information from these related columns, I can’t seem to get the connected block details. Does anyone know a good way to retrieve this linked data?

Here’s a basic example of what I’m trying to do:

notion_db = client.databases.query(database_id='your_database_id')
for item in notion_db['results']:
    linked_property = item['properties']['Related_Column']['relation']
    # How do I get the actual data from the linked item?

I’ve looked through the Notion API docs but couldn’t find a clear solution. Any help or pointers would be greatly appreciated!

I’ve worked extensively with the Notion API, and retrieving linked data can indeed be tricky. Here’s a solution that’s worked well for me:

def get_linked_data(client, linked_property):
    linked_data = []
    for relation in linked_property:
        page = client.pages.retrieve(page_id=relation['id'])
        linked_data.append(page['properties'])
    return linked_data

notion_db = client.databases.query(database_id='your_database_id')
for item in notion_db['results']:
    linked_property = item['properties']['Related_Column']['relation']
    linked_info = get_linked_data(client, linked_property)
    # Process linked_info as needed

This approach efficiently fetches the linked data for each item. Just be cautious of API rate limits with large datasets. Consider implementing pagination or batching if you’re dealing with numerous relations.

hey emmad, i’ve dealt with this before. you gotta make a separate api call for each linked item. something like:

for relation in linked_property:
    linked_page = client.pages.retrieve(page_id=relation['id'])
    # now u can access the linked data

hope that helps! let me know if u need more info

I’ve encountered this issue before while working on a project that heavily relied on Notion’s relational databases. The key is to use the Pages API endpoint to fetch the linked data. Here’s an approach that worked for me:

for item in notion_db['results']:
    linked_property = item['properties']['Related_Column']['relation']
    for relation in linked_property:
        linked_page = client.pages.retrieve(page_id=relation['id'])
        linked_data = linked_page['properties']
        # Process the linked_data as needed

This method allows you to access all the properties of the linked page. Just be mindful of API rate limits if you’re dealing with a large number of relations. You might want to implement some form of caching or batch processing to optimize performance.

Also, don’t forget to handle potential errors, as some linked pages might not be accessible due to permissions or other issues.
