You can see the documentation here
Mahmood

Also be sure you added the host to the host file of your os

Invalid block tag on line 32: 'else', expected 'endblock'. Did you forget to register or load this tag?

Read python template documentation... Maybe you're using space somewhere or maybe you're initialising the template wrongly....
Anurag
Check for spaces... And any extra braces

You might have opened a block but forget to {%endblock%}

class CourseMetaData(models.Model):
name = models.CharField(max_length=400)
price_total = models.FloatField()
modules_total = models.IntegerField()
price_per_module = models.FloatField(
editable=False, default=price_total / modules_total)
price_per_module is giving error saying: TypeError: unsupported operand type(s) for /: 'FloatField' and 'IntegerField'
what can I do to automatically calculate the per module price by division?

Riad
price_per_module = models.FloatField(

won't work. anyway, just fixed it by overriding save method
Riad
def save(self, *args, **kwargs):
self.price_per_module = round(
(self.price_total / self.modules_total), 2)
super().save(*args, **kwargs)
Rafael
or you can write the method
for emample
Rafael
Maxim
def save(self, *args, **kwargs):
self.price_per_module = round(
(self.price_total / self.modules_total), 2)
super().save(*args, **kwargs)
in this way you will lose the value of price_per_module if it is passed
Rafael
def calculate_price(self):
self.price_per_module=self.price_total/float(self.mofule_total)
and call it in save()
Riad
what does it matter?
how price_per_module will take input when editable is False? also, can you suggest a better way?

If the value of a field is determined only by the values of other fields, why store it at all?

hi guys, I have a hotel booking form and that form shown in each hotel page. When someone fills it, a letter goes to me. But I want to send hotel name along in that letter. But the problem is I don't know how to get that hotel name.
If I do this :
hotel = Hotels.objects.get(pk=1)
I am able to get hotel name. But how can I get pk automatically for that form? In this case I know exact pk, but what if I don't know? As this form will appear on any hotel.

This depends on how you’re creating and processing the form data, but if you’re using modelform, overriding the save method might be helpful here.
Like the second code in here, the saved object can be accessed in the save method like obj = super().save(commit=False)

Also this might give another idea how to get the same thing

I don't know if you used something like
specifichotel<str:pk>
in the urls
with that you can get the specific hotel name as the pk and then insert it into the letter
Suren
This is what I mean, if I indicate pk, I am getting hotel name, but getting this pk automatically while using CrateView looks like a problem. I understand it is possible if not using class view
Suren
class HotelBooking(models.Model):
name = models.CharField(max_length=255)
email = models.EmailField()
check_in = models.DateField(verbose_name='Check-in')
check_out = models.DateField(verbose_name='Check-out')
persons = models.IntegerField(default=1, verbose_name='Persons')
message = models.TextField(blank=True)
created_at = models.DateTimeField(auto_now_add=True)
Suren
I don't know if you used something like
specifichotel<str:pk>
in the urls
with that you can get the specific hotel name as the pk and then insert it into the letter
my url looks like:
path('booking/hotel/<slug:hotel_slug>/', HotelBookingFormView.as_view(), name='hotel_booking'),

my url looks like:

So you can always have the hotel slug to know which hotel is 🙂

Hello everyone, can you tell me how to make a global action. I want to make a form in the admin panel by which you can upload a csv file and update (according to my scenario) all the data. I can't find a solution at all.
UPD
It is not tied to any entity. The data is abstract, I want to preprocess it and write down the result of my calculations
