Because the site admin is sending a message to themselves, there is only one user in the topic_allowed_users, and `.last` returns nil.
Attempt to recognize this situation and continue, or bail without doing anything if this somehow happens another way.
* 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.
We want to wrap the `Ember.run.debounce` function and internally call `Ember.run` instead when running tests.
This commit changes discourseDebounce to work the same way as `Ember.run.debounce`.
Now that `discourseDebounce` works exactly like `Ember.run.debounce`, let's replace it and only use `DiscourseDebounce` from now on.
Move debounce to discourse-common to be able to reuse it in different bundles
Keep old debounce file for backwards-compatibility
You might wonder why this matters. It turns out in some locales like
French, we replace quotation marks with « and » -- this should likely
not happen before BBCode is parsed but that is not the case for this
plugin. The plugin has code to handle this situation, but it means extra
spaces are inserted around the time zone which breaks it.
This fix allows us to supply extra whitespace and will show the correct
time zone.
Using arrow functions changes `this` context, which is undesired in tests, e.g. it makes it impossible to setup things like pretender (`this.server`) in `beforeEach` hooks.
Ember guides always use classic functions in examples (e.g. https://guides.emberjs.com/release/testing/test-types/), and that's what it uses in its own test suite, as do various addons and ember apps.
It was also already used in Discourse where `this` was required. Moving forward, it will be needed in more places as we migrate toward ember-cli.
(I might later add a custom rule to eslint-discourse-ember to enforce this)
Due to the new enhanced copy-paste handling, the URL would be included in the user's reply as code, too!
By surrounding the link in angle brackets, we prevent the bot from accidentally including the link itself and spoiling the surprise.
I considered having the bot automatically edit the user's post to remove the backticks. I very quickly ran into a problem with spurious whitespace, and it would also look _super weird_ for the bot to edit your post when that's not what's being taught.
The seemingly bare link not automatically embedding is also weird, but slightly less so.
Fun fact: this doesn't work on localhost, because the onebox engine refuses to issue requests to localhost :)
In newer Embers jQuery is removed. There is a `find` but it only returns
one element and not a jQuery selector. This patch migrates our code to a
new helper `queryAll` which allows us to remove the global.
More seriously: discobot wasn't reacting properly if users used their
emoji keyboard to insert a real herb emoji, which works just as well
in a real post.
While we're here, use String#include? instead of constructing a new regexp.
