How to set model default value to a result bring returned by a function?
I've got a function inside my model which generates a random value for the model field and I need to set that value as a default for the model field. I've got the following model class Info(TimeStampedModel): info_id = models.UUIDField(primary_key=True) generated_url = models.TextField( null=False, blank=False, default=random ) def random(self): return 'customer.random.domain.com.' + ("".join(random.choices(string.ascii_uppercase + string.digits, k=5))) I wish the default value for the generated_url to be coming from the method inside the model named as random. but I get the following exception at Runtime: TypeError: random() missing 1 required positional argument: 'self' If I add parenthesis at the end of the function name as generated_url = models.TextField( null=False, blank=False, default=random() ) Then in that case I get a compile time error as the same: TypeError: random() missing 1 required positional argument: 'self' -

Search for user first name and last name together in django
I have a web page where it display the user's details such as their first name and last name, username, email etc. But I only can search either the user's first name or the last name in the search bar, how do I make it so that the user is able to type both the user's first name and last name and display the details out?

init function inside serializer class in django rest framework
This is a question of comprehension rather than code issue. I came across a code snippet of other person who has used init function inside the serializer class. I had to write update code on it. I wrote overriding the update method inside that serializer class which is as follows: class ProfileInfoApiview(UpdateAPIView): serializer_class = ProfileInfoSerializer def get_object(self): return self.request.user My serializer that i have wrote: class ProfileSerializer(serializers.ModelSerializer): class Meta: model = User fields = ["name", "mobile","user_type"] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) print("iam init") for field in self.fields: self.fields[field].required = True def update(self, instance, validated_data): print("iam update") user = instance user_type = validated_data.get("user_type") if user_type: if user_type == "student": Student.objects.create(user=user) if user_type == "parent": Parent.objects.create(user=user) if user_type == "teacher": Teacher.objects.create(user=user) instance.save() super(ProfileSerializer,self).update(instance,validated_data) return instance The confusion here is the init function that was written above. I just wrote the update function. The init was there already. Even if I remove the init function it works as expected and even I keep it there, it works fine. The print command is working that means init is working. But what is its use there?? If it does something why it is working when I removed it?? When is the init function called … -
Django Migrate table creation not consistent - multiple Legacy Databases

How to maintain user session across different devices and browsers from the access code email link in django
After validating the user, I'm sending out the access token to user's email along with the link to come back to the same page. [![Access Token email][1]][1] [1]: https://i.stack.imgur.com/OWezf.png This works well when the user opens the email in the same browser where he has been validated but if he opens the mail on his mobile or some other browser and clicks the link, he is taken back to the first validation page where he has to enter his user details again. How can I maintain the same session across different platforms in Django. I know there are some methods to do that like, we need an API which takes an encrypted request id as a parameter which will be included as a token in the access code email link to landing page. The API will decrypt the encrypted request id and then return the payload back associated to the same request id and we can use the data on the Front End to identify the user and resume the access-code verification step. But I donno, how to implement that or if there is any better solution? -

Free text in Select2ListView django-autocomplete-light
:) I'll expose my case as detailed as possible: I'm using the functionality of autocomplete to automatically populate a value that is dynamic into the form. The form has several values, when you fill the first 3 I'm able to run an operation (with those values) and return a suggested value to the user. I needed to adapt a bit the return of parameters but I achieved it with Select2ListView class MyFunctionAutocomplete(autocomplete.Select2ListView): def get_list(self): if not self.request.user.is_authenticated: return [""] try: field1_pk = self.forwarded["field1"] field2_pk = self.forwarded["field2"] field3_pk = self.forwarded["field3"] except AttributeError: return [""] try: ObjField1 = ModelField1.objects.get(pk=field1_pk) ObjField2 = ModelField2.objects.get(pk=field2_pk) ObjField3 = ModelField3.objects.get(pk=field3_pk) return_value = ObjField1.get_result(param1=ObjField2, param2=ObjField3) except (ModelField1.DoesNotExist, ModelField2.DoesNotExist, ModelField3.DoesNotExist): return [""] return [return_value] With this code I'm able to do what I need when the requirements (forwarded value) are present. So far, so good My problem: I cannot ADD any value as an extra option. This value IS NOT a ForeignKey, it's a simple Float. I want the user to be able to use my suggested value or instead just replace it by another value of their choice. Let's say in the dropdown they have the value 3.22221 and they want to write 12.11.

Issue Django Migrations Tree - Deployment Pythonanywhere
guys I have been having this issue when managing Django migrations on deployment, and I would like yo know what approach should I take: I am developing an application using Django and I am using Pythonanywhere to deploy the webapp, I am using sqlite as the database. I understand the Django Migrations work like a tree or a sequence (001, 002), but every time I make a change in a field locally it works fine because the tree have been save and the sequence have not changed, but when deploying the changes through github (having deployed the webapp and calling the migrations and migrate command, which creates another migrations files and sequence), usually I got an error indicating that the migration tree is broken; so I have to go to the app's migration folder and delete them and call again the migrations and migrate command. This is causing me a lot of problems due that I do not want to mess with schema of the database and loss the information. So, It is just me or anyone else is having this issue the migrations tree, not only on pythonanywhere but on others servers. Thank you guys! -
