Jeg har lavet endnu et Django-eksperiment med https://ugenr.dk som det store forbillede.
På https://wallnot.dk/kalender kan du altid finde en Mayland-style-kalender med helligdage og ugenumre. Kalenderen understøtter år 1 til 9999.
Den er lavet med tre side-funktioner: En der altid viser nuværende halvår (kalindex), en der viser et hvilket som helst halvår (kalperiod) og en der kan vise et hvilket som helst år (kalyear). Alle tre funktioner kalder en fjerde funktion get-dates der returnerer datoer i kalenderen for det år og/eller halvår, der efterspørges.
Her er views.py:
from django.shortcuts import render
import datetime
from workalendar.europe import Denmark # Module containing most Danish holidays
from django.http import Http404
# Function to return all calendar dates and other context data
def get_dates(year, period, now):
now_isocalendar = now.isocalendar()
### HOLIDAY LIST FOR YEAR IS GENERATED ###
# Create dictionary with all holidays of the year
holidays = Denmark().holidays(year)
all_holidays = {}
all_holidays[datetime.date(year,5,1)] = ["Første maj", "Særlig dag"]
all_holidays[datetime.date(year,6,5)] = ["Grundlovsdag", "Særlig dag"]
all_holidays[datetime.date(year,12,31)] = ["Nytårsaften", "Særlig dag"]
holiday_lookup = {
"New year": ["Nytårsdag", "Helligdag"],
"Holy Thursday": ["Skærtorsdag", "Helligdag"],
"Good Friday": ["Langfredag", "Helligdag"],

}
for holiday in holidays:
# Check for two holidays on same day
if holiday[0] not in all_holidays:
all_holidays[holiday[0]] = (holiday_lookup[holiday[1]][0], holiday_lookup[holiday[1]][1])
# If two on the same day, names are concenated
else:
all_holidays[holiday[0]] = (holiday_lookup[holiday[1]][0] + "/" + all_holidays[holiday[0]][0] , holiday_lookup[holiday[1]][1])
### DATES FOR YEAR ARE GENERATED IN A DAY AND MONTH DIMENSION ###

Sidens skabelon index.html ser en lille smule rodet ud (af hensyn til at minimere sidens størrelse). Skabelonen genererer en tabel ved at gennemgå alle dagene i kalenderen og tilføje særlige layout-regler for lørdage, søndage, helligdage, den nuværende uge, dag og ugenummer osv.
Her er den del af den, der benytter sig af Djangos skabelon-funktioner. (Resten af koden kan du finde ved at bruge “view source” på https://wallnot.dk/kalender):
