* Update filtering_rules_modal.html
* Update email.html-fragment
* Update email.md
Why remove:
* For self-hosters, payment-related features are unused and dead weight
* For SaaS (any would-be Healthchecks.io competitors), the existing
payment handling logic is not very useful either, as it would need to
be heavily modified to match their business model, pricing, chosen
payment gateway
* For the hosted service (Healthchecks.io), the up-to-date billing code
lives in a private fork of this repo. Maintenance is easier if this
repo does not have an older, diverging version of the same
functionality
A few payment-related bits are staying at least for time being:
* the "USE_PAYMENTS" setting
* the hc.payments.models.Subscription model
* tiny stubs for the "Pricing" and "Billing" pages
They are used in various places in the code and templates,
and I think ripping them out in one go would be too disruptive.
* Use the custom-styled checkbox
* Use PNG instead of icon font for channel kind logos
* Show channel's description the same way as in the channels list
(using a reusable template, templates/front/channel_description.html)
* MVP for notification groups.
* Addressed review comments.
* Push notification group to the front.
* Updated icons.
* Reduce code duplication.
* Show groups at the top.
* Add label to group forms.
* Add checkboxes for integration selection.
* CSS for checkboxes.
* Added tests for group notify.
Pagination, filtering, and result counting in Ping admin is tricky
as the pings table can contain millions of rows.
We previously used "select reltuples from pg_class" trick to
estimate the total number of rows. This only works on Postgres,
and does not handle WHERE filters.
This commit removes the search box, and changes the pagination
template to allow pagination between pages 1-9 and nothing more.
