This also resolves a race condition scenario. Even if the report gets
rendered via websockets before the controller response is rendered then
the fallback script loads the report again. It's not the most beautiful
but probably okay until we replace websockts altogether.
I'm leaving websockets in at the moment because it can render the report
much quicker than polling can.
The helpers are more convenient but also allow us to add options like
smooth scrolling. I thought that looked nicer and is less confusing.
Please note that the `scroll_into_view` helper uses the `targets`
attribute instead of `target`. That attribute needs CSS selectors with a
leading `#` for ids.
I'm adding TurboPower for the scroll_into_view action. It adds all the
nice CableReady actions to Turbo Streams.
Note that I omitted `block: "start"` because that option is the default
in Javascript. And the generic `action` method doesn't support
parameters like this anyway. I'll work on that in the next commit.
I also re-introduced a race condition by rendering the "loading"
indicator after triggering the report rendering job. I'm planning to
resolve that later.
It wasn't really necessary, but I'm going to need this list in a moment, so we might as well use it.
Also it allows us to ensure the options are listed in a certain order.
Also maybe it will help protect against corrupt preferences.
The preference will be set from the admin interface in a new commit
It would be nice if we had an array/list type for preferences. Probably not too hard to implement, but this will do.
- Fix the scenario when per_page is selected as 100 and next page is clicked, then per_page is empty in the request.
- Expected behavior should be that it retains the per_page selected previously
- New variant unit_value is empty, so +VariantUnits::OptionValueNamer.new(variant).name+ returns ""
- Now we are making sure that new variant unit_value won't be empty
Sending large reports via Cable Ready is unreliable. The events are
dropped at an unknown point and the report is never displayed to the
user. Instead we just send a link to the report via Cable Ready and
offer a button to load the report on screen.
This has the UX benefit of warning the user about the size as well.
Weaker devices can struggle rendering big HTML documents.
