Datetime dictionary group by Date Key
I have been heavily customizing an admin.py page where it shows the history of a user accessing specific endpoints. My client, however, wants me to group this list by date. The list is also the work of my customization. Let me show you what I mean. class UserAdmin(BaseUserAdmin): form = UserChangeForm add_form = UserCreationForm list_display = ('email', 'level', 'is_admin', 'is_active', 'user_counts') def user_counts(self, x): return x.counts.count() list_filter = ('is_admin',) fieldsets = ( (None, {'fields': ('email', 'password',)}), ('Personal info', {'fields': ('level',)}), ('Permissions', {'fields': ('is_admin', 'is_active',)}), (None, {'fields': ['user_counts_detail']}), ) readonly_fields = ['user_counts_detail'] def user_counts_detail(self, x): visits = [{"id": a.id, "date": a.date_time.date().strftime("%Y-%M-%d"), "time": a.date_time.time().strftime("%H:%M:%S") } for a in x.counts.all()] return visits Here the 'visits' list contains the id and the date and the exact time of each visit. However, the list is not as organized and can be a bit cryptic for non-developers. Below is the screenshot of the admin page. My question is: Is there anyway I can group such dictionaries by "date" key? I tried to find a way to do grouping in list comprehension but I failed to find any way to do this. Thanks a lot in advance! -
