Re: django models

[Soumen Khatua]

Yes,You are right as_data is custom made function inside the same
class,here is the code:



def as_data(self):
"""Return the address as a dict suitable for passing as
kwargs.Result does not contain the primary key or an associated user."""
data = model_to_dict(self,exclude=['id','user'])
if isinstance(data['country'], Country):
data['country'] = data['country'].code
if isinstance(data['phone'], PhoneNumber):
#as_e164 is a phonenumber format information
data['phone'] = data['phone'].as_e164
return data


But here other is an argument so we need to pass it then without passing
how we can compare with self.as_data varibale?

Thank you for your response.

django models

[Soumen Khatua]

Hi Folks,

I didn't  understand this code please help me to understand this code.

class AddressQueryset(models.QuerySet):
def annotate_default(self, user):
# Set default shipping/billing address pk to None
# if default shipping/billing address doesn't exist
default_shipping_address_pk, default_billing_address_pk = None, None
if user.default_shipping_address:
default_shipping_address_pk = user.default_shipping_address.pk
if user.default_billing_address:
default_billing_address_pk = user.default_billing_address.pk
return user.addresses.annotate(
user_default_shipping_address_pk=Value(
default_shipping_address_pk, models.IntegerField()),
user_default_billing_address_pk=Value(
default_billing_address_pk, models.IntegerField()))


default_shipping_address & default_billing_address_pk is available in my
User table it is a foreignkey of Address table  and  addresses is also
avialable in my User table as ManytoManytoField refering to same Address
Table and the last i'm using this inside Address table just like this :
objects = AddressQueryset.as_manager()

Re: Redirect

[Soumen Khatua]

Thanks for your help. But it should be redirect to these custom page if and
only if  I'll click login button and at the same time it should not
redirect to custom page if it is coming by loginrequired functionality.

Can you share me the code, please if it is possible.

Thank you once again.

NotImplementedError: This backend doesn't support absolute paths.

[Soumen Khatua]

Hi Folks,

I'm using AWS S3 Bucket to store media folder(images) but I want to resize
each every image in 300*300. So, I'm overriding the save method inside
django model class. But I'm getting one error caled:
*   NotImplementedError: This backend doesn't support absolute paths.*

*My django models look like:*

* class Profile(models.Model):*













*user = models.OneToOneField(AUTH_USER_MODEL,
on_delete=models.CASCADE,related_name="profile")profile_pic
= models.ImageField(default = 'profile.jpg',upload_to =
user_directory_path, null = True)def save(self, *args, **kwargs):
  super().save(*args, **kwargs)img =
Image.open(self.profile_pic.path)if img.height > 300 or img.width >
300:output_size = (300, 300)
img.thumbnail(output_size)img.save(self.image.path)*



I don't know how to solve this issue.

Thank you in advance

soumen

Restriction to create multiple instance

[Soumen Khatua]

Hi Folks,

Actually I'm extending user model as foreignkey into my own model called
Skills. So, suppose a user called X has skill of python and another user
called Y has the same skill set then I'm creating two instance into my
Skills table. But I want to do something like if X and Y have same skill
then they should be under same hood which python(skill) like python---(X,
Y) and if Y's another skill match with some others users then it should be
like Django(Y, Z). I know it is related to many to many relationship
but I don't know how to implement it. I'm also searching about it if you
people know how to solve it then it will save lots of time.

Thank you in advance.

filter on multiple tables

[Soumen Khatua]

Actually I want to filter all users those are matched with currently logged
in users based on location or education details like maybe institute_name
or specialization. Is it possible to search in multiple tables?!
I almost spent 2 days but still I stuck in the position.
Any help would be appreciated.

Thank You

Regards,
Soumen

*class Profile(models.Model):user = models.OneToOneField(
settings.AUTH_USER_MODEL,on_delete = models.CASCADE,

Re: filter on multiple tables

[Soumen Khatua]

Hi,

whenever I'm trying to filter as per your convention I'm getting some error
like FieldError:
*Eg.* *profile =
Profile.objects.filter(education__profile__institute_name="IIT KGP")*

of course, I'm getting this error because Profile is working here as a
Foreign Key, in Education table.

actually I want to fetch all the users those are from the same Institution
or Specialization or location.


Thank you for your response and time.

Regards,
Soumen

User table inside custom table

Hi Folks,

Actually my problem is very simple, here I'm calling to those users I'm
following but whenever I'm sending the data inside the serializers.I'm not
getting any value. I don't know what is happening here?!


*models.py---*






*class Follow(models.Model):follower = models.ForeignKey(User,on_delete
= models.CASCADE,related_name = 'following')followee =
models.ForeignKey(User,on_delete = models.CASCADE,related_name =
'followers') created_at = models.DateTimeField(auto_now_add = True,
null = True)updated_at = models.DateTimeField(auto_now = True, null =
True)class Meta:   unique_together = ("follower", "followee")*










*views.py--class FolloweeAPIViewList(APIView,
PaginationHandlerMixin):def get(self,request,*args,**kwargs):followee_qs =
Follow.objects.filter(follower = request.user).select_related('followee')
  serializer = UserFollowSerializer(followee_qs,many = True)return
Response(serializer.data,status=status.HTTP_200_OK)serializers.py--*











*class UserDetailSerializer(serializers.ModelSerializer):class Meta:
model = Userfields =
('full_name','email','phone_number','bio')class
UserFollowSerializer(serializers.ModelSerializer): user =
UserDetailSerializer(read_only=True) class Meta:  model =
Follow  fields = ('user','created_at')*


any help will be appreciated.

Re: Capture Content Id

[Soumen Khatua]

Yeah but in this way the time complexity will be very high, just think if
I'll have more than 1 million post than it will check all the field if it
is available or not.
However my query is different I want to fetch the data based on ID only but
I want to make url as slug  name, so it means the function will take slug
as a parameter not ID.

muliple queryset result

[Soumen Khatua]

Hi Folks,

Actually I have one *Primary *Table called *CustomUser *and I'm extending
this model as *Foreign *Key in *UserContactDetails model*. So now
basically *one
user have multiple contact details.* But whenever I'm applying *filter
*on *Primary
Table field* as well as *Foreign Key table* field, this queryset is
returnning  multiple Object inside queryset, like If my *ContactDetails *have
3 numbers of record for a user then it's returning the same record 3 number
of times inside queryset, can you guys tell me, How can I solve this
problem? I almost spend three hours on it, please help me.

*models.py*
**




















*class CustomUser(AbstractBaseUser, PermissionsMixin):email =
models.EmailField(_('email address'), unique=True)company_name =
models.CharField(max_length = 150)sap_code =
models.CharField(max_length = 150)is_staff =
models.BooleanField(default=False)is_active =
models.BooleanField(default=True)date_joined =
models.DateTimeField(default=timezone.now)USERNAME_FIELD = 'email'
REQUIRED_FIELDS = []objects = CustomUserManager()class
UserContactDetails(models.Model): user_details =
models.ForeignKey(CustomUser, related_name = 'usercontactdetailes',
related_query_name = 'usercontactdetaies', on_delete = models.CASCADE)
address = models.CharField(max_length = 150) mobile_no =
models.CharField(max_length = 150) primary_contact =
models.BooleanField(default = False)*


*views.py*
**

*query = request.GET.get('param')*





* user_data = CustomUser.objects.filter(
 Q(usercontactdetaies__address = query)|
 Q(usercontactdetaies__mobile_no = query)|   Q(company_name__exact =
query) |   Q(sap_code__exact = query)  )*

* >,
>, >]>*

*Instead of returnning one matched object inside queryset it's returnning
three matched object because I have three contact details for this user.*


*Thank you in advance*

*Regards,*
*Soumen Khatua*

Djago Rest framework Error

[Soumen Khatua]

Hi Folks,

I'm getting this error when I declared like this:


def post(self, request):
serializer = ProfileSerializer(data=request.data)
username = request.user.username
user_details = User.objects.get(username = username)
if serializer.is_valid():
serializer_data = serializer.save(commit=False)
serializer_data.user = user_details
serializer_data.save()

 File
"/home/sou/halanx/env/lib/python3.6/site-packages/rest_framework/serializers.py",
line 188, in save
"'commit' is not a valid keyword argument to the 'save()' method. "
AssertionError: 'commit' is not a valid keyword argument to the 'save()'
method. If you need to access data before committing to the database then
inspect 'serializer.validated_data' instead. You can also pass additional
keyword arguments to 'save()' if you need to set extra attributes on the
saved model instance. For example: 'serializer.save(owner=request.user)'.'


please help me guys for this issue!!!

Thank You
