Django CBV with pagination from ajax request and filtering
I have a class based ListView which is called by an ajax request where I also may pass some filtering params. The template should be paginated. Every thing is working fine. The only issue I cannot switch to the second or third page. The shown content is always the same, the one from the first page. The pagination is displayed well in the template.

Why doesn't my Django application on AWS EC2 doesn't read data from DB?
So I have my Django application running on AWS EC2. The application is a CRUD application, where users can freely create posts. I've just created a post, but wasn't able to see the post in my application. I've checked the admin, and made sure that the data is saved perfectly. It just doesn't show up on the page where it's supposed to be. This worked perfectly fine in the local server, before deploying. What could be the problem here? Thanks. *I'm using Postgres for the engine. -
Multiple Instances Of One Model In A Single Form
A user can have many books attached to his account. Each book a user has also has a model holding data unique to that User/Book pair: class BookData(models.Model): user = models.ForeignKey(User, related_name='user_book_data', on_delete=models.CASCADE) book = models.ForeignKey(Book, on_delete=models.CASCADE) read = models.BooleanField() class Book(models.Model): title = models.CharField(max_length=200) author = models.CharField(max_length=200) On a User's profile page I am displaying a table of all that User's Books along with their title, author and a checkbox for 'read'. Displaying the title and author are easy as these do not need a form as the user cannot edit this data. The checkbox 'read' however does need a form as the user can mark each book as being read or not. My problem is how to get all instances of BookData with a foreignKey to user within a single form. I would usually populate forms like this form = Form(instance=request.user.userform), but obviously this wont work. I'd imagine it's something like form = StudentModuleDataForm(StudentModuleData.objects.filter(student_id=studentUserModel.student.id)) I also read about formsets, but I think these are more for when users can add extra fields to a form. Thank you. -

Django Rest Framework : Login
I'm trying to make a django rest API. I've already created the registration API, now, I want to create the login API. In my form, I'm sending two data : email and password. I would like to check if there is an account that matched with these two fields. I don't really know if what I am doing is the good way to do a login api. Here is my code : views.py : ... #Log in @api_view(['POST', ]) def log_in(request): if request.method == 'POST': data = {} email = request.POST.get['email'] password = request.POST.get['password'] password = hashlib.sha1(password, encode('utf-8')) account = memberArea.objects.filter(email = email, password = password) if account: data['succes'] = "Successfully connected" data['id'] = account.id data['email'] = accound.email else : data['error'] = "email and password doesn't match !" return Response(data) When I run my code, I get this error : 'method' object is not subscriptable. I think it's because email and password are not QuerySet. If it's the method to login an user, how can I turn email and password into QuerySet ? If there is another way which is commonly used to make login api, what is it? Thanks by advance for your help. -
Django filtering large dataset taking too long
I know there have been a lot of questions regarding this subject, but I couldn't find any of my case. My problem is rather simple. In my influencer app, I have Note model which contains about 30 fields: class Note(models.Model): desc = models.TextField() likeCount = models.PositiveIntegerField() commentCount = models.PositiveIntegerField() ... tags = models.ManyToManyField(Tag) postTs = models.DateTimeField(null=True) And there is more than 1 million Notes in my PostgreSQL database hosted by AWS RDS. Now when I execute the following code: notes = ( Note.objects.filter(desc__icontains='some word') .values("likeCount", "collectCount", "shareCount", "commentCount", "postTs")[:10] ) print(len(notes)) # Output: 10 it takes around 7 seconds. The resulting SQL query is: SELECT "influencer_note"."likeCount", "influencer_note"."collectCount", "influencer_note"."shareCount", "influencer_note"."commentCount", "influencer_note"."postTs" FROM "influencer_note" WHERE UPPER("influencer_note"."desc"::text) LIKE UPPER('%some word%') LIMIT 10 I think I have done pretty much everything to optimize the query (such as selecting the only necessary fields and limiting the number of data -- 10 is obviously a small number), but it's still taking abnormal amount of time. What are the possible causes for this problem and how can I further optimize this? Ultimately, I need to make a chart with the filtered queryset, which is why I need a solution other than pagination or LIMIT. Thank you in … -

Django Rest Serializer with double foreign keys
Hey I'm rather new to the whole REST framework. I'm doing a project where I want to get all the users and their projects they are currently working on. However I'm not quite sure how I would go about linking the serializer together for the JSON output. Right now my 3 models look like this class User(models.Model): first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) email = models.EmailField() def __str__(self): return str(self.first_name) class ProjectUser(models.Model): project = models.ForeignKey("Project", on_delete=models.CASCADE) user = models.ForeignKey("User", on_delete=models.CASCADE) is_lead = models.BooleanField(default=False) class Meta: unique_together = (("project", "user"),) def __str__(self): return str(self.id) class Project(models.Model): name = models.CharField(max_length=255) client = models.Charfield(max_length=255) def __str__(self): return str(self.name) I think a custom serializer would be best for this, but I'm lost as to how to query the data to it. -

Confusion with templates in django

Should I create two separate templates for that, that is, one template that uses col-sm-4 and the other template that does not use col-sm-4? Would that be correct? -
