now the problem is i want to show the username , total amount collections and total orders by individual users(is_agent).no name will be repeated twice though the queryset can have multiple orders agains a user.
i just want to show a users orders total amount and total deliveries in a table row,then other row will be for other users. N.B.filtering (delivery_status="Complete")
update:
agents = User.objects.filter(is_active=True,is_agent=True)
for agent in agents:
agent_id = agent.id
all_orders = Order.objects.filter(user_id = agent_id, delivery_Status="Pending", delivery_time__month = date,
delivery_time__year = year)
now in here i want every agents total delivery count and total amount collected from them but not like showing same user's all querysets but instead i want only by his name will appear once in the table and all deliveries total amount and total deliveries into that row just like the given table
itried this but this has no track of which collection is for whom
individual_orders = []
final_list = []
grand_final_list = []
order_amount = []
individual_orders_count = []
agents = User.objects.filter(is_active=True,is_agent=True)
for agent in agents:
agent_id = agent.id
all_orders = Order.objects.filter(user_id = agent_id, delivery_Status="Pending", delivery_time__month = date,
delivery_time__year = year)
if all_orders:
individual_orders.append(all_orders)
individual_orders_count.append(len(all_orders))
cash_collection = Order.objects.filter(user_id = agent_id, delivery_Status="Pending", delivery_time__month = date,
delivery_time__year = year).values('amount').aggregate(Sum('amount'))
for k,v in cash_collection.items():
if v:
order_amount.append(v)
for query in individual_orders:
for entry in query:
final_list.append(entry.user.username)
grand_final_list = list(dict.fromkeys(final_list))
this table
maybe this helps you?
all_orders = Order.objects.filter(user_id = agent_id, delivery_Status="Pending", delivery_time__month = date,
delivery_time__year = year).values(id, username=F(user__username)).annotate(total_amount = Sum('amount')).annotate(total_deliveries = Count('id))
finally i found a way i am showing the demo here
def driver_deliveries(request):
name = {}
data = []
count = Order.objects.filter(driver__is_driver=True).distinct()
for i in count:
query = Order.objects.filter(driver_id=i.driver.id,delivery_Status="Complete").count()
name[i.driver.username] = data
data.append(query)
data = []
print(name)
for k,v in name.items():
print(k)
for i in v:
print(i)
return render(request,'user/driver_deliveries.html',{'name': name})
I'm having a weird issue, I have a models' hierarchy, an abstract User class:

phone = PhoneNumberField()

notifications_token = models.CharField(max_length=255, unique=True, null=True)
photo = models.ImageField(null=True)
person_in_contact = models.CharField(max_length=32, null=True)
active = models.BooleanField(default=False)
confirmedEmail = models.BooleanField(default=False)
confirmedPhone = models.BooleanField(default=False)
completedProfile = models.BooleanField(default=False)
visible = models.BooleanField(default=True)
#property
def is_active(self):
return self.active
# def __str__(self):
# return "Client : " + self.user_name + " Email:" + self.email
def get_email(self):
return self.email
USERNAME_FIELD = 'user_name'
REQUIRED_FIELDS = ['user_name', 'phone', 'password']
class Meta:
abstract = True
then a person class and a company (no issue with this one) class that inherit from this one:
class Person(User):
GENDER = (('F', 'FEMALE'), ('M', 'MALE'))
name = models.CharField(max_length=50, null=True)
surname = models.CharField(max_length=50, null=True)
adress = models.CharField(max_length=255, null=True)
birth_date = models.DateField(null=True)
gender = models.CharField(max_length=1, choices=GENDER, null=True)
age = models.IntegerField(null=True)
def age(self):
today = date.today()
return today.year - self.birth_date.year
# def __str__(self):
# return super().__str__() + " Name : " + self.name
class Meta:
abstract = True
as you can see, the only field that's IntegerField() is the age field.
now i have a Traveller and a Driver classes that inherit from the person class,
the issue is the age field, doesn't show in the database, unless i override it in one of the classes, that's what i did, i override it in traveller so it appeared in the database, but didn't override it in the driver, so it didn't show.
Traveller:
class Traveller(Person):
photo = models.ImageField(null=True, upload_to='travellers/profile_pictures')
age = models.IntegerField(null=True)
class Meta:
verbose_name_plural = 'Travellers'
Driver:
class Driver(Person):
rating = models.DecimalField(default=0, decimal_places=1, max_digits=3)
driving_license = models.CharField(max_length=50, null=True)
insurance_number = models.CharField(max_length=50, null=True)
company = models.ForeignKey(TransportCompany, on_delete=models.DO_NOTHING, null=True)
photo = models.ImageField(null=True, upload_to='drivers/profile_pictures')
i need to know how i can fix this, or what's the issue, any help is appreciated.
The reason this happens is because your age field has the same name as the age function. As a result, the age = ... field is ignored by Python in favor of the age function, since that is the last time you defined the age variable.
For the same reason the age field pops up in sublasses: you defined an age variable over there, and that takes precedence over the "inherited" age method.
You should rename one of the two. For example with:
class Person(User):
GENDER = (('F', 'FEMALE'), ('M', 'MALE'))
name = models.CharField(max_length=50, null=True)
surname = models.CharField(max_length=50, null=True)
adress = models.CharField(max_length=255, null=True)
birth_date = models.DateField(null=True)
gender = models.CharField(max_length=1, choices=GENDER, null=True)
_age = models.IntegerField(null=True)
def age(self):
today = date.today()
bod = self.birth_date
before_dob = (today.month, today.day) < (bod.month, bod.day)
return today.year - self.birth_date.year - before_dob
class Meta:
abstract = True
Note that the calculation of the age was not completely accurate: if we are before the birthday of that year, you need to subtract one from the age.
I've been asked to design a way for people to search through multiple models on criteria they enter and allow them to export any number of fields they select.
Example:
User enters "Teacher" as a term for Job Title and "Google" for a Work Site Location but want to export "Employee ID", "First Name", "Last Name", "Date of Birth"
I'm sure this is possible, but I'm at a complete loss for where to start.

reservation_number = models.CharField(verbose_name='Номер брони', max_length=200, blank=True)
What I want is to have ability to edit Day on Reservation page
I try the following as in the django docs
class ReservedDaysInline(admin.TabularInline):
model = Reservation
extra = 1
class ReservationAdmin(admin.ModelAdmin):
inlines = (ReservedDaysInline,)
class DayAdmin(admin.ModelAdmin):
inline = (ReservedDaysInline,)
admin.site.register(Reservation, ReservationAdmin)
admin.site.register(Day, DayAdmin)
But it doesnt work.
What am I doing wrong ?
Try this from doc
class ReservedDaysInline(admin.TabularInline):
model = Reservation.reserved_days.through
extra = 1
class ReservationAdmin(admin.ModelAdmin):
inlines = (ReservedDaysInline,)
exclude = ('reserved_days',)
In Django 1.6.1 I have a vehicle model which might zero or up to 2 traded-in units. Every time I edit any record, whether the change is trade-in instance #1 or instance 2, both records are updated with values instance #2.
Vehicle model:
class Vehicle(models.Model):
stock = models.CharField(max_length=10, blank=False, db_index=True)
vin = models.CharField(max_length=17, blank=False, db_index=True)
#vinlast8 = models.CharField(max_length=8, blank=False, db_index=True)
make = models.CharField(max_length=15, blank=False)
model = models.CharField(max_length=15, blank=False)
year = models.CharField(max_length=4, blank=False)
registry = models.IntegerField(blank=True, verbose_name='Reg #', null=True)
plate = models.CharField(blank=True, null=True, max_length=10)
tagno = models.IntegerField(blank=True, null=True, verbose_name='Tag #')
tag_exp = models.DateField(blank=True, null=True, verbose_name='Tag Exp')
Tradein model:
class TradeIn(Vehicle):
TradeInVehicle = (
(1, 'First vehicle'),
(2, 'Second vehicle'),
)
vehicle_sale = models.ForeignKey(VehicleSale)
tradeinpos = models.IntegerField(choices=TradeInVehicle)
lienholder = models.CharField(max_length=15, blank=True, null=True, verbose_name='L/holder')
lhdocrequested = models.DateField(blank=True, null=True, verbose_name='D/Requested')
lhdocreceived = models.DateField(blank=True, null=True, verbose_name='D/Received')
class Meta:
db_table = 'tradein'
def __unicode__(self):
return self.stock
def save(self, *args, **kwargs):
self.stock = self.stock.upper()
self.vin = self.vin.upper()
return super(TradeIn, self).save(*args, **kwargs)
The related sections on view is:
These sections are related to request.GET
current_vehicle = VehicleSale.objects.get(pk=pk)
tradeIns = current_vehicle.tradein_set.all().order_by('tradeinpos')
# Also add tradein_form to t_data so it can be rendered in the template
t_count = tradeIns.count()
if t_count == 0:
t_data['tradein1_form'] = TradeInForm()
t_data['tradein2_form'] = TradeInForm()
if t_count >= 1 and tradeIns[0] and tradeIns[0].tradeinpos == 1:
t_data['tradein1_form'] = TradeInForm(instance=tradeIns[0])
t_data['tradein2_form'] = TradeInForm()
if t_count == 2 and tradeIns[1] and tradeIns[1].tradeinpos == 2:
t_data['tradein2_form'] = TradeInForm(instance=tradeIns[1])
Now these are related to request.POST:
if 'tradein-form' in request.POST:
if tradeIns.count() > 0:
if tradeIns[0]:
tradein1_form = TradeInForm(request.POST, instance=tradeIns[0])
if tradein1_form.is_valid():
tradein1_form.save()
if tradeIns[1]:
tradein2_form = TradeInForm(request.POST, instance=tradeIns[1])
if tradein2_form.is_valid():
tradein2_form.save()
While reviewing contents of request.POST, it does contain any change I make in either instance. But always, the 2nd instance is saved.
What am I missing or have wrong?
