- introduce bootstrap tabs to switch the views
- introduce `content_for :heading_class` to remove the padding below the bootstrap tabs
- update the rss-image to use a svg, adopted from https://icons.getbootstrap.com/icons/rss/ (without the outer border)
- move rss- and new-button away from the view-switching actions
- the `@tag` logic was broken. introduce new link to remove the tag-filter; the tabs keep the filter once given; use params[:tag] directly in the view
- use `&.` syntax nil-safety so we can remove `@display_name`
When the user wants to enable an external authenticator we need
to redirect to omniauth but that now needs to be a POST so use a
redirect that preserves the POST method.
Fixes#3114
This adapts to two changes in place handling by Nominatim:
* Place links that are computed by Nominatim are now found in
extratags['linked_places']. Keep the check for extratags['place']
as this may contain an explicitly mapped place label.
* Use address rank for guessing the admin level. This gets normalised
by Nominatim with respect to country-specific use of admin_level.
Also adds additional labels for admin levels, so that we now have
complete coverage for all levels that are in use in OSM.
It doesn't make a huge difference, since rails caches all the results
of the queries generated by point.trace lookups, but at least it cuts
down on the logs.
We can avoid using `html_safe` in various circumstances, through alternative approaches like i18n keys ending in `_html` or using `safe_join` to avoid converting via unsafe string types.
The `_html` keys approach only work for ActionView helper version of `t`, not the base `I18n.t` method.
It's a convention in rails to name your mailers with a Mailer suffix, and is also common to name the class after the recipient (e.g. User, Admin). So UserMailer seems a reasonable choice.
As we don't have any way to actually find the active sessions for
an account we instead store a fingerprint in the session, and refuse
to use any session with a different fingerprint.
