Django form and redirect -

my code follwing : in views.py:

class projectdetailview(generic.detailview):     model = project     template_name = 'project_details.html'  class projectcreate(createview):     model = project     fields = ['project_name']     template_name = 'project_form.html'  def create_invite(request):     if request.method == "post":         invite_form = inviteform(data=request.post)         if invite_form.is_valid():             email1 = invite_form.cleaned_data['email1']             email2 = invite_form.cleaned_data['email2']             email3 = invite_form.cleaned_data['email3']             email4 = invite_form.cleaned_data['email4']             email5 = invite_form.cleaned_data['email5']             in invite_form.cleaned_data:                 invite = invitation.create(i)                 invite.send_invitation(request)             print("the mail went")             return reverse('website:projectdetails', kwargs = {'pk' : project.pk} )         else:             print("your form not valid")     else:         invite_form = inviteform()     return render(request, 'team_invite.html', {'invite_form': invite_form}) 

in form.py:

from django import forms   class inviteform(forms.form):     email1 = forms.emailfield(label='email 1')     email2 = forms.emailfield(label='email 2')     email3 = forms.emailfield(label='email 3')     email4 = forms.emailfield(label='email 4')     email5 = forms.emailfield(label='email 5') 

urls.py:

from django.conf.urls import url website import views  app_name = 'website'  urlpatterns = [     url(r'^candidateindex/$', views.candidateindex.as_view(), name='candidate_index'),     url(r'^hrcreate/$', views.projectcreate.as_view(), name='hr_create'),     url(r'^project/(?p<pk>[0-9]+)/$',views.projectdetailview.as_view(), name='projectdetails'),     url(r'^project/add/$',views.projectcreate.as_view(), name='addproject'),     url(r'^invite/$',views.create_invite, name='addteam'), ] 

like can see: have form send email invites user. using form have 2 issues :

1) seems instead of taking value in input email, seems take variable email1 or email2 ect..

2) when try redirect detail page using project pk error:

django.urls.exceptions.noreversematch: reverse 'projectdetails' keyword arguments '{'pk': <property object @ 0x10ecf79a8>}' not found. 1 pattern(s) tried: ['website/project/(?p<pk>[0-9]+)/$'] 

any ideas ?
