`poll` plugin was publishing on `/polls/[topic_id]` every time a non-first post was created. I can't imagine this being needed. It regressed 3 years ago in https://github.com/discourse/discourse/pull/6359
* DEV: Remove spec that we no longer need.
As far as we know, the migration has been successful for a number of
years.
* FIX: Validate number of votes allowed per poll per user.
They can use the remove vote button or select the same option again for
single choice polls.
This commit refactor the plugin to properly organize code and make it
easier to follow.
The endpoint the existence of the poll and if the current user can see it. It
will facilitate using a poll programmatically, especially if we'd like to create an external poll through a theme component.
Some plugins hook into Post after save to set custom fields and save again.
For example: https://github.com/discourse/discourse-category-experts/blob/main/lib/category_experts/post_handler.rb#L27
Problem is that in case like that `raw_changed?` is false but all callback are triggered. `extracted_polls` is class atribute therefore that should be reset with each attempt.
That was causing an error:
```
#<ActiveRecord::RecordNotUnique: PG::UniqueViolation: ERROR: duplicate key value violates unique constraint
"index_polls_on_post_id_and_name" DETAIL: Key (post_id, name)=(8967, poll) already exists.
```
Over the years we accrued many spelling mistakes in the code base.
This PR attempts to fix spelling mistakes and typos in all areas of the code that are extremely safe to change
- comments
- test descriptions
- other low risk areas
Headings with the exact same name generated exactly the same heading
names, which was invalid. This replaces the old code for generating
names for non-English headings which were using URI encode and resulted
in unreadable headings.
Poll markdown processing failed when there were any heading elements preceding a poll.
(Issue originally reported in babbebfb35 (commitcomment-42983768))
Adds an optional title attribute to polls. The rationale for this addition is that polls themselves didn't contain context/question and relied on post body to explain them. That context wasn't always obvious (e.g. when there are multiple polls in a single post) or available (e.g. when you display the poll breakdown - you see the answers, but not the question)
As a side note, here's a word on how the poll plugin works:
> We have a markdown poll renderer, which we use in the builder UI and the composer preview, but… when you submit a post, raw markdown is cooked into html (twice), then we extract data from the generated html and save it to the database. When it's render time, we first display the cooked html poll, and then extract some data from that html, get the data from the post's JSON (and identify that poll using the extracted html stuff) to then render the poll using widgets and the JSON data.
This required properly plumbing the guardian into the serializer.
Notably, the default state in the client was not changed - if you haven't voted in
the poll, you need to click the button to view the results instead of the results
being immediately visible on page load.
Implements https://meta.discourse.org/t/-/138108
The bug was mentioned here: https://meta.discourse.org/t/poll-name/136436
I added specs to cover existing behaviour and refactored can_see_results method.
Guard condition should apply only if the poll result setting is set to `staff_only`.
In other cases, user can see results when the poll result setting is set to `always` or user voted or poll is closed.
They were relying on a pristine message bus, however current implementation
still uses redis, stuff can get held up and we can end up publishing
distributed cache messages in the middle invalidating the tests
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
Includes support for flags, reviewable users and queued posts, with REST API
backwards compatibility.
