It should work two issue
1.Url is not matching your need to visit that is where you are getting that reverse error.
2.To pull that value through kwargs you need to use the get request so override the get method otherwise it should work fine.

--Hi,I'm trying to figure out how to fill a form field in the background using form_valid. However, everything I've tried doesn't work.As you can see in the model, there is a job field with a foreign key to Job.class JobDocket(models.Model):
EQUIPMENT_TYPE = (
('1', 'Air Conditioning'),
('2', 'Heating/Heat-Pump'),

end_time = models.TimeField()
rate = models.FloatField(default=80.00)
mileage = models.IntegerField()
description = models.CharField(max_length=1000, help_text='Description of work carried out', blank=False)

total_min = str(end_min - start_min)
total_time = total_hours + " hours" " and " + total_min + " minutes"
return total_time
def total_labour_price(self):

def __str__(self):
return str(self.technician)
def get_absolute_url(self):
return reverse('jobs:detail', kwargs={'pk': self.pk})In the View, I'm trying to get the pk for the job to automatically fill the field so that the logged in user doesn't have to.class JobDocketCreate(CreateView):
model = JobDocket
form_class = JobDocketForm
template_name = 'jobs/job_docket_create.html'
def get_success_url(self):
return reverse('jobs:my_job_dockets')
def form_valid(self, form):
form.instance.technician = self.request.user
# form.instance.job_id = Job.objects.get(pk=self.kwargs['job_id'])
# print(form.instance.job_id)
return super(JobDocketCreate, self).form_valid(form)
def get_initial(self):
Job.objects.get(pk=self.kwargs.get('job_id'))
initial = super(JobDocketCreate, self).get_initial()
initial['job'] = Job.objects.get(pk=self.kwargs['job_id'])
print(initial)
return initial
I've tried passing the pk of the job through the URL like so;path('<int:job_id>/jobdocketcreate/', JobDocketCreate.as_view(), name='create_job_docket'),
I have the template link referencing the job like this;<a class="tg-btn" href="{% url 'jobs:create_job_docket' job.pk %}">Add Job Docket</a>But I can't get it to work, the error I keep getting is;NoReverseMatch at /jobs/1/jobdocketcreate/
Reverse for 'create_job_docket' with arguments '('',)' not found. 1 pattern(s) tried: ['jobs\\/(?P<job_id>[0-9]+)\\/jobdocketcreate\\/$']Has anyone got experience making this work? How did you do it?Here is the Job model if you need it;class Job(models.Model):
JOB_TYPE = (
('1', 'Service'),
('2', 'Repair'),
('3', 'Quotation'),
('4', 'Consultation'),
('5', 'Report'),
('6', 'Design'),
)
ACCOUNT_TYPE = (
('1', 'Existing Customer'),
('2', 'Charge to Account'),
('3', 'New Customer'),
('4', 'Pre-Paid/C.O.D'),
('5', 'Issued and Acc App'),
)
company_name = models.ForeignKey(Company, related_name='jobs', verbose_name="Company Name", on_delete=models.CASCADE)
contact_person = models.CharField(max_length=50)
contact_number = models.IntegerField()
contact_person_email = models.EmailField(max_length=100, blank=True, null=True)
site_address = models.CharField(max_length=100)
job_type = models.CharField(choices=JOB_TYPE, max_length=50, default='1')
account_type = models.CharField(choices=ACCOUNT_TYPE, max_length=50, default='1')
job_details = models.CharField(max_length=1000)
created = models.DateTimeField(default=now, blank=True)
def __str__(self):
return str(self.company_name)
def get_absolute_url(self):
return reverse('jobs:detail', kwargs={'pk': self.pk})
And the form:class JobDocketForm(forms.ModelForm):
description = forms.CharField(max_length=1000, widget=forms.Textarea)
date = forms.DateField(widget=DatePicker)
start_time = forms.TimeField(widget=TimePicker)
end_time = forms.TimeField(widget=TimePicker)
class Meta:
model = JobDocket
exclude = 'rate', 'created', 'technician', 'job',
fields = (
'site_equipment', 'date', 'start_time', 'end_time', 'mileage', 'description'
)I've looked on StackOverflow for solutions like in the links below, but they don't work.I would really appreciate some help.Thanks,Sam
