This commit introduces a way to fetch the "serialized voters" for
multiple polls.
* Use a single query to fetch voters for all types of polls
* Refactor to introduce all_serialized_voters
* Cache serialized voters
These fields are often used when serializing topics which may contain
multiple polls. On average, serializing a poll took 2+N queries where N
is the number of options. This change reduces the number of queries to
3, one for each field (Poll#voters_count, PollOption#voters_count and
Poll#has_voted?).
The "migration to Glimmer" has been broken out here from #27155 to make the review process less onerous and reduce change risk:
* DEV: migrates most of the widget code to Glimmer in prep for IRV additions
* NB This already incorporates significant amounts of review and feedback from the prior PR.
* NB because there was significant additional feedback relating to older Poll code that I've improved with feedback, there are some additional changes here that are general improvements to the plugin and not specific to IRV nor Glimmer!
* There should be no trace of IRV code here.
Once this is finalised and merged we can continue to progress with #27155.
Skipping methods we don't use gives us mem/perf gains (minuscule but still), but more importantly fixes warnings about `Poll#open` (created by `enum :status`) conflicting with some internal AR method. 😃
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.
* DEV: Remove with_deleted workarounds for old Rails version
These workarounds using private APIs are no longer required in the latest version of Rails. The referenced issue (https://github.com/rails/rails/issues/4306) was closed in 2013. The acts_as_paranoid workaround which this was based on was removed for rails > 5.
Switching to using a scope also allows us to use it within a `belongs_to` relation (e.g. in the Poll model). This avoids issues which can be caused by unscoping all `where` clauses.
Predicates are not necessarily strings, so calling `.join(" AND ")` can sometimes cause weird errors. If we use `WhereClause#ast`, and then `.to_sql` we achieve the same thing with fully public APIs, and it will work successfully for all predicates.
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.
* FEATURE: Staff only poll results
These changes allow only staff to see the results of a poll.
Non-staff users will be shown a screen like this:

The "Votes are public" message has been removed from the info section,
and the button to show the votes has been replaced with a message
stating the results will only be shown to staff.
* Update PR based on feedback
* Update plugins/poll/app/models/poll.rb
make sure we return a boolean

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
