Is it possible to see who voted in polls?

(Tobias Eigen) #1

I just tested out polls for the first time in a while, and it works quite well and I like it.

But I would like to have an open poll so we can see who voted for which option. Is this possible? Is there any way to see who voted for what?

You can run the following query to get a list of users who voted and their selected poll options.
Please choose the appropriate query for your Discourse version.

Query for Discourse v2.2.0.beta5 and newer

-- [params]
-- post_id :post_id
-- text :poll_name = poll

SELECT AS user_id, u.username, v.poll_option_id AS option_id, o.html AS option_html
FROM polls p
       JOIN poll_votes v ON ( = v.poll_id)
       JOIN poll_options o ON ( = v.poll_option_id)
       JOIN users u ON (v.user_id =
WHERE p.post_id = :post_id AND = :poll_name
ORDER BY u.username, v.poll_option_id

Query for older versions of Discourse up to v2.2.0.beta4

-- [params]
-- post_id :post_id
-- text :poll_name = poll

SELECT votes.user_id, users.username, votes.option_id, options.html AS option_html
  SELECT value1 ->> 'id' AS id,
    value1 ->> 'html' AS html
  FROM (
    SELECT json_array_elements(value :: JSON -> :poll_name -> 'options') AS value1
    FROM post_custom_fields
    WHERE post_id = :post_id AND name = 'polls' AND value :: JSON -> :poll_name ->> 'name' = :poll_name
  ) option_values
) options
       JOIN (
  SELECT key :: INTEGER AS user_id,
    trim(json_array_elements(value :: JSON -> :poll_name) :: TEXT, '"') AS option_id
  FROM json_each((
    SELECT value :: JSON
    FROM post_custom_fields
    WHERE post_id = :post_id AND name LIKE 'polls-votes'
) votes ON ( = votes.option_id)
       JOIN users ON (votes.user_id =
ORDER BY users.username, votes.option_id

How to find post_id

You can use the following query if you need to find the right post_id.

-- [params]
-- topic_id :topic_id
-- int :post_number = 1

FROM posts
WHERE topic_id = :topic_id AND post_number = :post_number

it works! thanks so much. :fireworks:

is there a query for quickly identifying the post ID containing polls? I used the .json URL method but it was surprisingly cumbersome to find the right post within it.

Default values are specified like this:

I updated the query. It’s now a lot simpler. :slight_smile:
