how to utilize same list view for search and category queryset in django
I am trying to build functionality in my Django app in which we can get data with two methods: Using Search Selecting a Category Since both of them require to get data from the dataset, I am wondering if there is a way I can utilize same ListView (not a CBV) to output data. urls.py path('datalist/<slug:category_slug>/' views.problemlist, name="problem_list_category"), path('datalist/search/' views.problemlistbysearch, name="problem_list_search"), views.py def problemlist(request, category_slug): qs = DataModel.objects.get(category_slug=category_slug) return render(request,'list.html',{'qs':qs} ) def problemlistbysearch(request): if request.method == 'GET': querry = request.GET.get('name') objlst = DataModel.objects.all() qs = objlst.filter(title__icontains=querry) return render(request, 'seach.html', {'qs':qs}) -

Django: save(commit=False) on formset CBV is triggering customized model save() actions
I'm using CBV CreateView to display a couple of pages with formsets to the user. When the model behind a given formset/CreateView is a common one (it will became clearer later), everything works fine using the following logic on the view: class Create(CreateView): ... def form_valid(self, formset): instances = formset.save(commit=False) for instance in instances: instance.user = self.request.user instance.save() return super(Create, self).form_valid(formset) However, on one of the models, I had to add extra actions to the model save() method. Namely, I need to create child objects when the parents are saved. Something like: class Parent(models.Model): ... def save(self, *args, **kwargs): super().save(*args, **kwargs) self.child_set.create(...., *args, **kwargs) In this particular case, the child object is being created twice and I believe that the formset.save(commit=False) is the culprit. I tried replacing the child_set.create() for child = Child(...parameters, parent=self) child.save(*args, **kwargs) But it yields the same result. How can I prevent that? -

AWS Postgresql RDS instance "does not exist" with docker-compose and Django
My RDS and web container are not connected. But I did all the database-related settings in Django's settings, and I also set up AWS RDS properly. What should I do more? This is DATABASES of settings file of Django. DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "NAME": env("SQL_DATABASE"), "USER": env("SQL_USER"), "PASSWORD": env("SQL_PASSWORD"), "HOST": env("SQL_HOST"), "PORT": env("SQL_PORT"), } } I skipped the docker-compose.yml with enginx-proxy or TLS. When I tested in local, I made and mounted DB containers on docker-compose, butin prod environments, I didn't make DB containers because I use RDS. Will this be a problem? Please help me.

Creating a index for a Django Full Text Search
I'm implementing full text search on a blog using Django 3.2 and PostgreSQL 12.8. I have a database with 3.000 posts and my searchbar searches through post_title, post_subtitle and post_text.

Which software to use to build scalable web site that supports forums, e-commerce, and collaboration?
I am not sure where to ask this question, hope you guys don’t mind I post it here. Which open source software that has most built-in support to build a web site with the following characteristics: Users can form sub-groups and a user can belong to multiple sub groups. Each group has more than one moderator with majority needed to delete postings. Reputation rating for users A user can view list of other users that meet specified characteristics Private messages between any users or set of users A user has his/her own web pages and tools to manage them. Discussion topics that viewable to all or sub-groups Live discussion (while looking at common document) that viewable to all or sub-groups Transaction support between any two users Scalable (to support more users) by essentially adding more hardware with minimal programming if possible. With my extremely limited knowledge, it seems something based on WordPress, Django-CMS, or phpBB are the choices. Although it seems none of them support all/most of the above spec. Many thanks for your thought. -
What is the usage of 'quaryset' attribute of the Django 'CreateView'?

Using two tables or single table with multiple rows?
I have two functions one is used for "requesting documents" (it can be more than 3) and another function is "Sending documents" (it also can be more than 2) Now my problem is both has various purpose, so should i need to create two table or single table with a differentiation ? How to handle this efficiently ? Option1: Create two table named "RequestedDocuments" & "SendDocuments" and save accordingly or Option2: Create a single table named "Documents" and have field named "Type" and save accordingly with some types like "request" & "send"?** My another concern is, In one of the view i need to show all the two in separate tables and in another view i need to show only one of the above ! So which is more efficient ? -

django Model.objects.create not immediately assign primary key to variable how to access that?
I have django Student model like below class Student(models.Model): id = models.IntegerField(primary_key=True) name = models.CharField(max_length=20) score = models.DecimalField(max_digits=10, decimal_places=2) def __str__(self): return f"Student(id: {self.id}, name: {self.name}, salary: {self.score})" I have created some users in database also below is django shell output >>> s = Student.objects.create(name="erik", score=90) >>> print(s) Student(id: None, name: erik, salary: 90) # <----- here is showing id None >>> Student.objects.all() <QuerySet [<Student: Student(id: 1, name: alex, salary: 40.00)>, <Student: Student(id: 2, name: john, salary: 60.00)>, <Student: Student(id: 3, name: erik, salary: 90.00)>]> when i have called Student.objects.all() then it is showing id. I want to get id from s variable because i am performing unit testing like below. class GetSingleStudentTest(TestCase): def setUp(self): Student.objects.create(name="student1", score=50) Student.objects.create(name="student2", score=55) Student.objects.create(name="student3", score=80) Student.objects.create(name="student4", score=36) def test_get_single_student(self): # get API response response = client.get(reverse("student-detail", kwargs={"pk" : self.student2.pk })) # get data from db student = Student.objects.get(pk=self.student2.pk) serializer = StudentSerializer(student) self.assertEqual(response.data, serializer.data) So when i have tried to access self.student2.pk it is None like we saw in django shell also. So how can i get that id? because as i know Model.objects.create creates a user and also save into database then why id is None here?

Best practice Django : make sure User.username is unique even when User is deleted
I would like to know your thoughts about the Django best practice to ensure the uniqueness of a field value, even if objects are deleted. For example I create a CustomerUser with username = "carlos" , delete this user, then if I create another CustomerUser with username= "carlos" I will get an error. models.py class CustomUser(models.Model): username = models.CharField(max_length=100 , unique=True) shell user_one = CustomUser.objects.create(username="carlos") user_one.delete() user_two = CustomUser.objects.create(username="carlos") ---> This should not be possible. Should I save in another model all the usernames created or there is a Django function that assures the uniqueness of the username will be always True even after object deletion ? Thanks -

Lazy load pagination in django
I have a function that makes 100 queries to an API, however there is a rate limit of something like 15 requests per second. Therefore, I tried using Django EL(Endless) Pagination in order to get something like Twitter style pagination. The effect I wanted was something in which by default it would only show the first ten items, and once the user scrolls to end, it would load the next ten items. However, it seems that pagination only paginates the template, not the view in which the data is requested. It seems that what the pagination is doing is: Call the function to send 100 queries. Display first 10 elements. When user reach the end, call again the function to send 100 queries. Show another 10 elements. Basically, each time the next page is requested, the view function is called. The view function is something like this: def user_info(request, user_account, template="entry_list.html"): # Function that makes the 100 requests entry_list = helpers.get_summary_list(user_account) context = { "entry_list": entry_list, } if request.is_ajax(): template = "entry_list_page.html" return render(request, template, context) Then in the template: {% load el_pagination_tags %} {% lazy_paginate entries %} {% for entry in entries %} {# your code to show the … -

Django-contrib-comments fails to get authenticated user

AttributeError at /comments/post/ 'Account' object has no attribute 'get_full_name' class Poller(models.Model): poller_id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) created_by = models.ForeignKey(Account, on_delete=models.CASCADE) [..] The post_comment view fails here: def post_comment(request, next=None, using=None): data = request.POST.copy() if request.user.is_authenticated: if not data.get('name', ''): data["name"] = request.user.get_full_name() or request.user.get_username() # fails here My custom user model inherited from AbstractBaseUser: class Account(AbstractBaseUser): email = models.EmailField(verbose_name='email', max_length=60, unique=True) username = models.CharField(max_length=40, unique=True) [..] -

passing django database entries into messages within the line messenger api (linebot)
i would like the linebot to send all classes stored in the database, on a given a particular day, depending on the user input, through line messenger. e.g user types "hello" linebot responds with "hello" user types "monday" linebot sends monday's class schedule user types "studentlist(tutorname)" linebot sends all students in the list of that tutor so far, i can receive the echo, the linebot is storing the user data corectly in the model database too. the bot can differentiate between message type. (i.e "text", "image" etc) everything i seem to do stops the main messages being sent. How would be best to write the loops required to get my desired reponse? I was hoping to using the information in this way and pass that somehow into the message data = Lessons.objects.all().filter(headed_by__name="Tutor Name").filter(day__icontains="Monday") below is not working, and stops the rest of the elif functions from working. elif event.message.type=="text" | event.message.text=="Monday" : message.append(TextSendMessage(text='Monday? Coming right up')) line_bot_api.reply_message(event.reply_token,message) and this is the code that i am using to receive the messages currently @csrf_exempt def callback(request): if request.method == "POST": message=[] signature=request.META['HTTP_X_LINE_SIGNATURE'] body=request.body.decode('utf-8') message.append(TextSendMessage(text=str(body))) try: events = parser.parse(body,signature) except InvalidSignatureError: return HttpResponseForbidden() except LineBotApiError: return HttpResponseBadRequest() for event in events: if isinstance(event, …
