How Do I Detect And Properly Display Events On Calendar That Overlaps Months in Python?
I used a tutorial I found online to create an event calendar in Python. I've tried to improve it to schedule events that may have a start and end time range that overlap months. Meaning it may start in June and end in July. I've got it partially figured out...I can display the events based on the start day being lte day in the Python HTMLCalendar module. I can't figure out how to pick up the remaining day for July 1. June displays perfectly. Thanks in advance for any thoughts. Here's my code... HTMLCALENDAR Utility.. class Calendar(HTMLCalendar): def __init__(self, year=None, month=None, dropdown=None): self.dropdown = dropdown self.year = year self.month = month super(Calendar, self).__init__() # formats a day as a td # filter events by day def formatday(self, day, requests): requests_per_day = requests.filter(start_time__day__lte=day,start_time__month=self.month) d = '' for request in requests_per_day: d += f'<li> {request.get_html_url} </li>' if day != 0: return f"<td><span class='date'>{day}</span><ul> {d} </ul></td>" return '<td></td>' # formats a week as a tr def formatweek(self, theweek, requests): week = '' for d, weekday in theweek: week += self.formatday(d, requests) return f'<tr> {week} </tr>' # formats a month as a table # filter events by year and month def formatmonth(self, withyear=True): # … -

Reverse proxy in Nginx causes "SyntaxError: unexpected EOF while parsing in python"
I know there are a lot of similar questions to my question, and also I know how to fix the error. But I have no idea the reason for the error. ( So, please don't give my question immediately a -1, if you don't have time to read it all ) I changed HTTP to HTTPS in my Nginx, now I am getting the "SyntaxError: unexpected EOF while parsing". However, the code is still working locally with HTTP and HTTPS, and also it was working on the server with HTTP until I changed the proxy from HTTP to HTTPS. Here is my code: if filter_name == "kunde": konzern_qs = Konzern.objects.filter(kunde__name_slug__in=field_input).values_list("name") commitments = commitments.filter(expr_filter) | eval(" | ".join( ["commitments.filter(konzern='{}')".format(k[0]) for k in konzern_qs])) and the error: File "/home/webapps/visoon_backend/venv/lib/python3.6/site-packages/rest_framework/mixins.py", line 38, in list queryset = self.filter_queryset(self.get_queryset()) File "/home/webapps/visoon_backend/visoon_backend/visoon/views.py", line 1353, in get_queryset ["commitments.filter(konzern='{}')".format(k[0]) for k in konzern_qs])) File "<string>", line 0 ^ And this error appears only if konzern_qs = [] but if there is data, it is working.
