Discourse Data Explorer SQL Query

[JohnMcDonald]

I have a question that is very similar to (but different from) the question posted here: `DataExplorer::ValidationError: Missing parameter` when running Data Explorer queries with [params] via API.

My query in Data Explorer looks like this:

-- [params]
-- topic_id :topic_id

SELECT * FROM posts WHERE topic_id = :topic_id

This works fine in Data Explorer. Then, when I try and run it via the API I get:

{"success":false,"errors":["DiscourseDataExplorer::ValidationError: Missing parameter topic_id of type topic_id"]}'

Here is my python request:

headers = {
    'Content-Type': 'multipart/form-data;',
    'Api-Key': API_KEY,
    'Api-Username': USERNAME_SYSTEM
}

params = {"topic_id": 398}

response = requests.post(url="[REDACTED]/admin/plugins/explorer/queries/10/run", headers=headers, params=params)

I gather from the error than I cannot pass “topic_id” as a string, but I don’t see how else I can pass it as a key. Any thoughts on this?

The parameters are not passed in the URL.

Maybe something like: data={“params”: ‘{“topic_id”:"398"}’?

I had to try a lot of different alternatives, but this worked:

                         headers=headers, data={'params': '{\"topic_id\": "398"}'})```

So, the answer is a combination of that prior post (which said you have to escape the quotes when you are sending from a Windows machine and Arkshine's post which says it needs to be passed as data and not as a params kwarg.  What I find odd though, is I thought the whole point of the params kwarg in the Python requests module was to pass parameter information.

[Arkshine]

I’m glad it worked!

I tried sending Linux (wsl) or Windows; I don’t have the same issue, and it worked for both.

data = {
    'params': '{"topic_id": "3"}'
}

response = requests.post(
    url="http://localhost:4200/admin/plugins/explorer/queries/4/run", 
    headers=headers, 
    data=data
)
