QUESTION - Is there a way to add a property to an already existing collection?

[aviral-batra]

I don't know where else to ask, I was wondering how you can add a property to an existing collection?

[aviral-batra]

I found the answer myself:

If you edit the data structure of a block/collection, then you can sync it to notion using set, i.e. to add a new property:

cvb = client.get_block(collection_view_block_url)

# inserts a new property into the cached dictionary
cvb.collection.get()['schema']['NewProp'] = {
    "name": 'New property',
    "type": 'text'
}

# loads the cached schema into a variable to make it easier to manipulate
schema = cvb.collection.get()['schema']

# syncs the locally cached schema to the notion server
cvb.collection.set(path=['schema'], value=schema)

N.B. if you add force_refresh=True in the get method before you set the dictionary, you will get the original i.e. the one stored in the actual notion database, not the cached one. Until you use set(), the structure/collection/block is not updated.
