django 2.1 HTML form submitting to db error - django

Question

i am trying to post the data from html form to my db, however i get the error that the url does not exist. what am trying to do is later on turn the test form into dynamic add fields using HTML and Jquery rather than using formset for ease UI designing and handle it in dango back end.
also note that am assigning the foreign key which is the startup_name by passing it through the url to test view.
the code is as following:
models.py:
class Startup(models.Model):
author = models.ForeignKey(User, on_delete=models.CASCADE)
startup_name = models.CharField('Startup Name', max_length = 32, null = False, blank = False)
class Team (models.Model):
str_team = models.ForeignKey(Startup, on_delete=models.CASCADE)
name = models.CharField('Name',max_length = 32, null = False, blank = False)
position = models.CharField('Title/Position', max_length = 32, null = False, blank = False)
qualification = models.CharField('Degrees/Qualifications', max_length=32,null=False,blank=False)
views.py:
def create_startupform(request):
if request.method == 'POST':
form = startupform(request.POST)
if form.is_valid():
result = form.save(commit=False)
result.author = request.user
result.save()
return redirect('test', startup_id = result.pk)
else:
form = startupform()
return render(request, 'str_name.html', {'form': form})
def test (request, startup_id):
e = Startup.objects.values('startup_name')
if request.method == 'POST':
na = request.POST.get("name")
po = request.POST.get("position")
qu = request.POST.get("qualification")
ref = Team(name = na, position = po, qualification = qu, str_team = e)
ref.save()
return redirect('str_dashboard')
return render(request, 'test.html')
forms.py:
class startupform(forms.ModelForm):
class Meta:
model = Startup
fields = ('startup_name',)
widgets = {
'startup_name': forms.TextInput(attrs = {'class':'form-control'}),
}
def clean(self):
super ( ).clean ( )
startup_name = self.cleaned_data.get ( 'startup_name' )
startup_qs = Startup.objects.filter ( startup_name = startup_name )
if startup_qs.exists ( ):
raise forms.ValidationError ( 'This Startup Already Exist!' )
test.html:
<form id="add-extra" class="form" method="post" action = "{% url 'test' %}">{% csrf_token %}

URLS:
from django.urls import path
from . import views
urlpatterns = [
path ( 'str_dashboard/' , views.str_dashboard , name = 'str_dashboard' ),
path ( 'create_startupform/' , views.create_startupform, name = 'create_startupform' ),
path('test/', views.test, name='test'),
]
Error:
Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/test/
Using the URLconf defined in sourcing.urls, Django tried these URL patterns, in this order:

Answer 1

You are trying an url which is not in the urls.py:
urlpatterns = [
...
path('test/<int:startup_id>/', views.test, name='test'),
path('test/', views.test, name='test_base'), # add this
]
The url 'http://127.0.0.1:8000/test/' won't match because it would need to have 'startup_id' attached with your urls.py.
http://127.0.0.1:8000/test/1 would work.
If you do like i wrote above, make sure that your view is taking startup_id as optional. Or use another function for the call without startup_id.
