django - python - Skip weekend and public holiday when calculating duration between 2 datefield -


greeting everyone,

i have 2 datefield in form, start_date , end_date , floatfield called duration. figure out how automatically save duration without user input calculating duration of start , end date, how can give condition skip weekend, , particular public holiday?

any appreciated

below code :

model.py : 

class leave(models.model):     employee = models.foreignkey(employee, on_delete=models.cascade, related_name='+')     start_date = models.datefield()     end_date = models.datefield()     duration = models.floatfield(null=true, blank=true)

form.py :

class leavesdetailform(forms.modelform):     class meta:         model = leave         fields = ('employee', 'start_date', 'end_date', 'duration')         widgets = {'start_date': forms.dateinput(attrs={'type': 'date'}),                    'end_date': forms.dateinput(attrs={'type': 'date'}),                    'employee': forms.hiddeninput(),                    'duration': forms.hiddeninput()}

view.py :

def my_leaves_view(request):     """    leaves view     :param request:     :return:     """     form = leavesdetailform(request.post or none)         if form.is_valid():             inst = form.save(commit=false)             inst.start_date = form.cleaned_data['start_date']             inst.end_date = form.cleaned_data['end_date']             duration = (inst.end_date - inst.start_date).days             inst.duration = duration             inst.save()             return httpresponseredirect('/hrm/employee/leaves')     return render(request, 'hrm/employee/details/my_leaves.html', context)

a possible solution can use numpy's busday_count function:

import numpy np   def my_leaves_view(request):     ...     inst.duration = np.busday_count(inst.start_date, inst.end_date)     ...

which gives days count without weekends , holidays.

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj...
