Minor improvements

[germannp]

Just collecting small ideas :-)

• Show number of selected pilots when listing trainings?
• Write down useful information for new pilots (e.g. toilets, drinking water, parking spots, prices, ...)
• Add links to Birdwing and other partners
• Go back to page after updating signup from paginated trainings list
• Only to for next Saturday from Monday on, still go by default to today if it's Sunday
• Add columns to admin table of Training (e.g. max_pilots) and Signup (e.g. is_certain)
• Batch role change in admin panel
• Success URL when ending up on login and having to register
• Try 4.1's bulk_create for creating Trainings, as it might be able to update existing Trainings
• Make pre-filled texts when updating training a drop-up, they are not visible on mobile. Also color code might be nice.
• Check priority date is before start when bulk creating or updating trainings
• Ask for address in membership form
• Make form's error more useful (e.g. state which field is required, might have to set required=False and clean everything manually)
• Sign up for several days at once? Date range selector? Picking several trainings from list?
• Prefill stored Training.infos when updating Training!
• Fix margin between "Über uns" and "Partner" cards
• Explain, that we don't store postal addresses with holiday plans
• Use "einschreiben" everywhere (e.g. in "Über uns" we use "Anmeldung)
• Require is_certain or WholeDay for is_motivated?
• Add sidebar to contact.html and 404.html maybe too?
• Make upcoming trainings more readable: grey out count of canceled signups, warn-color for 75% and not WholeDay
• Print week day in signups success message, to make mistakes easier to notice
• add season begin and end to infos
• Add link to AirG and mention that we also have those demos
• sleeping options
• admin: sort signups by descending date, trainings too
• validate phones, apparently chrome fills in emails sometimes ... Also use these tags for readers?
• Make login cookies live longer than two weeks
• Assert no emergency mail was sent, before sending; currently I guess two orgas could be sending one at the same time 🤔
• Make emergency button clickable to list phone numbers of participants, and rather disable send button for emergency mail
• Paginate SignupListView by year (along the lines of ReportListView)
• Forward to QR code when paying by TWINT
• Add warning for earlier unpaid Signup in create_bill
• "Bitte Kassenstand erfassen" warning should not show up, when any cash_at_end is saved
• URL to Bilanz should be berichte/bilanz
• Welcome email after registration; someone was not sure whether registration worked 🤷 and might help to figure out with which email one registered 🤔
• Replace None with ? in list_reports before Report.cash_at_end is saved
• There might be a bug in update_bill when flights were paid (and not from abo)
• Aggregate TWINT transactions by week (as we get weekly receipts)
• ReportListView and BalanceView are getting slower with every report ...
• Show IBAN in create_absorption
• Redirect when creating report before sending emergency mail
• Add pull-to-refresh Works now on Firefox
• List all active pilots of season
• Yesterday's training is still listed for the one or two hours after midnight, when UTC is still yesterday; likely create_report also goes wrong ...
• Would be nice to have checkboxes for CTR/TMA, parking tickets, and briefing if new pilots are there, when creating a report.
• Use MessagesTestMixin.assertMessages() from Django 5
• Add Absorptions to TWINT revenue in balance
• Show amounts paid by the pilots in report_update table
• Show mode of transportation in report_update table
• Use Django standard password validation when creating account; currently you can use 123 as password, but not change one to 123 (because too short and too common)
• Show numbers of lift day passes & numbers of flights with Postauto in Bilanz
