I am trying to create an application where you can create project-based expenses, and each project should have a list of approvers who will approve the expense once uploaded to the project, how do I replicate this in Django.
What I tried to do.
I got the approvers into the form as a ModelMultipleChoiceField
self.fields['approvers'] = forms.ModelMultipleChoiceField(queryset=Profile.objects.all())
and saved it as a list into the database
def getApprovers(approvers):
id = []
for profile in approvers:
id.append(profile.id)
return id
in project create function
project.approvers = getApprovers(form.cleaned_data['approvers'])
I created a templatetag to display the list of approvers as the Profile Queryset objects. I tried to iterate over the saved list of approvers, but I keep getting errors
def approvers_list(approvers):
for profile in list(approvers):
profiles = [Profile.objects.filter(pk = i) for i in
list(approvers)]
return profile
I got this error
Field 'id' expected a number but got '['.
This is the result I got after changing the approvers_list method
def approvers_list(approvers):
p = []
for profile in list(approvers):
p.append(profile)
return p
This is the result
['[', '1', ',', ' ', '2', ',', ' ', '3', ']']
How can I turn this into a list of ids, so I can use it to get individual profiles of the approvers?
How can I get this to work best?
Here are the models
class Project(MiscClass):
owner = models.ForeignKey(Profile, on_delete=models.CASCADE, null=True, blank=True)
organisation = models.ForeignKey(Organisation, on_delete=models.SET_NULL, null=True, blank=True)
title = models.CharField(max_length=200, null=True, blank=True, unique=True)
slug = models.SlugField(max_length=500, null=True, blank=True, unique=True)

def __str__(self):
return str(self.title)
def save(self, *args, **kwargs):
self.slug = slugify(self.title)
super(Project, self).save(*args, **kwargs)
class Expense(MiscClass):
PROCESSING = 1
APPROVED = 2
DECLINED = 3
APPROVAL_STATUS = (
(PROCESSING, 'Processing'),
(APPROVED, 'Approved'),
(DECLINED, 'Declined')
)
owner = models.ForeignKey(User, on_delete=models.SET_NULL, blank=True, null=True)
title = models.CharField(max_length=300, null=True)
slug = models.SlugField(max_length=300 , null=True, unique=True)
amount = models.CharField(max_length=200, null=True, blank=True)
status = models.IntegerField(choices=APPROVAL_STATUS, default=PROCESSING)
description = models.TextField(blank=True, null=True)
refrence_number = models.CharField(max_length=300, unique=True, null=True)
category = models.ForeignKey('Category', on_delete=models.SET_NULL, null=True, blank=True)
date_due = models.DateTimeField(auto_now_add=False, null=True, blank=True)
merchant = models.CharField(max_length=200, null=True, blank=True)
expense_date = models.DateTimeField(auto_now_add=False, null=True, blank=True)
def __str__(self):
return str(self.title)
def save(self, *args, **kwargs):
self.slug = slugify(self.title)
return super(Expense, self).save(*args, **kwargs)
I want to update a field which is called level. My relation is like this. i am using django User model. Which is extended to Extended user like this below:-
class ExtendedUser(models.Model):
levels_fields = (
("NEW SELLER", "NEW SELLER"),
("LEVEL1", "LEVEL1"),
("LEVEL 2", "LEVEL 2"),
("LEVEL 3", "LEVEL 3")
)
user = models.OneToOneField(User, on_delete=models.CASCADE)
email = models.EmailField(null=True, unique=True)
contact_no = models.CharField(max_length=15, null=True)
profile_picture = models.ImageField(upload_to="images/", null=True)
country = models.ForeignKey(Country, on_delete=models.CASCADE, null=True)
city = models.ForeignKey(City, on_delete=models.CASCADE, null=True)
level = models.CharField(max_length = 120, null=True, blank=True, choices=levels_fields, default="NEW SELLER")
I have a field call "Level" which is full of choices. Now i have a model named Checkout
This is the checkout model :-
class Checkout(models.Model):
ORDER_CHOICES = (
("ACTIVE", "ACTIVE"),
("LATE", "LATE"),
("DELIVERED", "DELIVERED"),
("CANCELLED", "CANCELLED"),
)
user = models.ForeignKey(User, on_delete=models.CASCADE)
seller = models.ForeignKey(
User, on_delete=models.CASCADE, null=True, related_name='seller')
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now_add=True)
first_name = models.CharField(max_length=120)
last_name = models.CharField(max_length=120)
package = models.ForeignKey(OfferManager, on_delete=models.CASCADE)
quantity = models.PositiveIntegerField(default=0)
price = models.DecimalField(decimal_places=2, max_digits=10, default=0.00)
total = models.DecimalField(decimal_places=2, max_digits=10, default=0.00)
grand_total = models.DecimalField(
decimal_places=2, max_digits=10, default=0.00, null=True)
paid = models.BooleanField(default=False)
due_date = models.DateField(null=True)
order_status = models.CharField(max_length=200, choices=ORDER_CHOICES, default="ACTIVE")
is_complete = models.BooleanField(default=False, null=True)
I have another model which is called SellerSubmit and the checkout is the foreign key here. Here is the model :-
class SellerSubmit(models.Model):
checkout = models.ForeignKey(Checkout, on_delete=models.CASCADE, related_name="checkout")
file_field = models.FileField(upload_to="files/", null=True)
submit_date = models.DateField(auto_now_add=True, null=True)
def __str__(self):
return str(self.id)
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
Now when a seller post in the SUbmitModel it will update the level to LEVEL1. How can do it,
This is what i tried :-
def sellerSubmitView(request, pk):
form = SellerSubmitForm()
if request.method == "POST":
file_field = request.FILES.get("file_field")
try:
checkout = Checkout.objects.get(id=pk)
# print(file_field)
except:
return redirect("manage-order")
else:
SellerSubmit.objects.create(checkout=checkout, file_field=file_field)
checkout.order_status ="DELIVERED"
chk = checkout.is_complete = True
l = Checkout.objects.filter(is_complete = True).filter(seller=request.user).count()
print("Count:" + str(l))
if l > 5:
out = checkout.seller.extendeduser.level = "LEVEL1"
print(out)
checkout.save()
print(chk)
checkout.save()
return redirect("manage-order")
args = {
"form": form,
"checkout_id": pk,
}
return render(request, "wasekPart/sellerSubmit.html", args)
checkout.seller.extendeduser.level = "LEVEL1"
checkout.seller.extendeduser.save()
This should solve your problem
out = checkout.seller.extendeduser.level = "LEVEL1"
print(out)
checkout.seller.extendeduser.save()
checkout.save()
It's my bad that didn't notice ExtendedUser is not extended from User.
Please let me know if it's worked or not
I don't want to add data to the database, like what djangorestframework-datatables is trying to do with the POST request. I need to use a POST request instead of a GET request because the URI for the GET request is too long (I had to change nginx and gunicorn limits on the production server, to unlimited length (max wasn't enough) which opens the site up to ddos attacks, which is obviously not ideal.

Override the create method in ReportViewset
def create(self, request, *args, **kwargs):
serializer = self.get_serializer(data=request.data)
serializer.is_valid(raise_exception=True)
#self.perform_create(serializer)
headers = self.get_success_headers(serializer.data)
return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)
self.perform_create(serializer) is what access the database.
Hi I am recreating a website in django and this happens...
Django throw this error,
ValueError: save() prohibited to prevent data loss due to unsaved related object 'fk_deal'.
even though I have saved the foreign key related object. This is the view part.
if request.method == "POST":

The database was created from an existing MySQL database....
I send the data to the view using jquery POST....
I can't seem to find out what the problem is. Also even after saving the model if I print the id field it returns None instead....
Can somebody help me?
I have a question that I hope someone can help me with. I'm using a form to have the user select a "plan". Now I want to list all the members in the plan, in the form. I have a function 'get_owners' that grabs all the members in the plan, by using this function:
def get_owners(self):
owners = self.planmember_set.filter(ownership_type__code__in=["primary","joint"])
return owners
Only problem is that I get an output of:
[<PlanMember: Doe, John (Primary)>, <PlanMember: Doe, Jane(Joint Subscriber)>, etc]
Now is there a way for me to just show their names and the member type (the words in brackets)?
A bit of background code.
Here is my views.py:
if request.POST:
form = PlanMaturityYearForm(Plan.objects.all().filter(profile = p), request.POST)
if form.is_valid():
selected_plan = form.cleaned_data['plans']
plan = get_object_or_404(Plan, pk=selected_plan.pk)
investment_list = Investment.objects.all().filter(Q(plan = plan)).order_by('maturity_date')
context['investment_list'] = investment_list
context['plan'] = plan
context['today'] = now
context['current_yr'] = current_year
context['next_yr'] = next_year
context['show_report'] = True
else:
form = PlanMaturityYearForm(Plan.objects.all().filter(profile = p))
context['form'] = form
return render_to_response('reports/planmaturities_year.html', RequestContext(request, context))
And my forms.py:
class PlanMaturityYearForm(forms.Form):
def __init__(self, plans, *args, **kwargs):
super(PlanMaturityYearForm, self).__init__(*args, **kwargs)
self.fields['plans'] = forms.ModelChoiceField(
plans,
required=True,
widget=forms.Select(attrs={'size': 20}),
error_messages={'required':'Please select the plan you wish to build the report for',}
)

owners = self.planmember_set.filter(ownership_type__code__in=["primary","joint"]).values_list('name_field', 'ownership_type__code')
return owners
Write where and how you use get_owners if not correct.
