Querying for GroupBy in Django
class Author(models.Model): first_name = models.CharField(max_length=10) last_name = models.CharField(max_length=10, null=True, blank=True) def __str__(self): return f'{self.first_name} {self.last_name}' class Book(models.Model): name = models.CharField(max_length=100) author = models.ManyToManyField(Author, related_name='book_author') price = models.SmallIntegerField() def __str__(self): return self.name Hello there! I've been trying to group by the cost of books in the above model according to the author (as there can be multiple authors for a single book). I know it can be done using groupby but I don't know how to query for it in Django ORM, I tried searching the web but didn't get the relevant solution. What I'm trying to do is, for e.g., if a book 'Wonder' has two authors 'A' and 'B' and they have written together with other books as well, like 'Wonder' by 'A' and 'B' and 'New' by 'A' and 'B' So, I want to query for the books with the combination of their authors + a total cost field of all the books written by the authors (many-to-many author combination). If there is a way, please help and sorry for the bad English. -

Could not determine join condition between parent/child tables on relationship Product.collections
The relationship between Product and Collection is many to many. A product can be in many collections and each collection can have many products. For such case, I want to convert the django models to sqlalchemy in fastapi. Below is a table for product and collection in django models class Product(models.Model): product_type = models.ForeignKey( ProductType, related_name="products", on_delete=models.CASCADE ) name = models.CharField(max_length=250) slug = models.SlugField(max_length=255, unique=True, allow_unicode=True) class CollectionProduct(models.Model): collection = models.ForeignKey( "Collection", related_name="collectionproduct", on_delete=models.CASCADE ) product = models.ForeignKey( Product, related_name="collectionproduct", on_delete=models.CASCADE ) class Collection(models.Model): name = models.CharField(max_length=250, unique=True) slug = models.SlugField(max_length=255, unique=True, allow_unicode=True) products = models.ManyToManyField( Product, blank=True, related_name="collections", through=CollectionProduct, through_fields=("collection", "product"), ) background_image = VersatileImageField( upload_to="collection-backgrounds", blank=True, null=True ) I tried the below way to migrate django model to sqlalchemy.

How to access user details in all pages in django?
After login I want to access User details when ever I want (Particularly in navigation bar). I did not use user model provided in django. I created my own model like this for authentication. My database is stored in mysql on phpmyadmin(Xampp). AdminUser Modal class adminUser(models.Model): username=models.CharField(max_length=50) firstname=models.CharField(max_length=50) department=models.CharField(max_length=50) name=models.CharField(max_length=50) mail=models.CharField(max_length=50) id=models.IntegerField(primary_key=True) password=models.CharField(max_length=200) class Meta: db_table="admin_users" admin_users.py def login(request): if request.method == 'POST': username = request.POST.get('username') password = request.POST.get('password') if username is not None and password is not None: user=adminUser.objects.get(username=username) hashed_password = user.password is_check = bcrypt.checkpw(password.encode('utf8'),hashed_password.encode('utf8')) print(is_check) if is_check==True: return redirect(reverse('faq_index')) else: return render(request,'AdminUsers/login.html') return render(request,'AdminUsers/login.html') During the login User Details can be only access by login function but I want to access user details in all pages for navigation bar and also want to find out whether user is authenticated or not. As I am not using User Model in django so I can not user user.is_authenticated(). So How do I do this? -

import declarations may only appear at top level of a module and disallowed MIME type
I'm trying to load a script that includes an import statement, but Firefox shows the "import declarations..." error in the console. The import in my script looks something like this: import { foo } from './path/to/js/file'; I can get rid of this error by including type="module" as an attribute of the script tag in my HTML, but then I get a different error in the console: "Loading module from “http://localhost:8000/path/to/js/file” was blocked because of a disallowed MIME type (“text/html”)." It also shows a 404 in the console for the script I'm trying to import. Interestingly, I can get rid of both of these by appending .js to my import statement: import { foo } from './path/to/js/file.js'; But since file.js is part of a larger library with its own import statements, all subsequent import statements raise MIME type errors and 404s. I'm using Django as my backend framework and the application is in a docker container. What am I doing wrong? -

Iterate over variable and insert additional rows Postgres
Just to note, yes I have seen similar questions on here but none quite close enough for the particular issue. I have a table (let's call it 'table 1') in postgres with three columns based on a django model, 'ID' (auto incrementing value), 'affiliation', and 'entry'. What I need to do is take every entry where affiliation = 52, and then add an additional row with entry = query.entry and affiliation = 48 (just to reiterate, I need additional rows, not changed values). I also need to make sure that the entry + affiliation pair don't already exist. No matter what I do I get a syntax error! Any help? The latest call was: do $$ declare id_array int[]; begin insert into id_array table_1.entry where table_1.affiliation = 52; for id in id_array loop if not exists (select entry from table_1 where affiliation = 48) then insert into table_1 (affiliation, entry) values (48, id); else raise notice "already exists"; end if; endloop; end; $$ Any ideas? I'm at a complete loss...This is by far the most complex query I've ever ran. -

Django/Python change content.innerHTML to a src page
I am running a page that on a click, replaces the content in an iFrame. The JS in index.js looks like this: if (page == 'stationData') { content.innerHTML = '<h1>Station Data</h1>'; content.innerHTML += '<iframe class="site_data_tab" src="stationDataHTML.html"></iframe>'; } The old iFrame data goes away and the text "Station Data" appears as expected, but I can't figure out how to get the stationDataHTML.html page to appear in the iFrame. I've tried something like this: index.js: if (page == 'stationData') { content.innerHTML = '<h1>Station Data</h1>'; content.innerHTML += '<iframe class="site_data_tab" src="{% url \'data-stationData\' %}"></iframe>'; } urls.py: urlpatterns = [path('', AboutView.as_view(template_name="stationDataHTML.html")),] views.py: class AboutView(TemplateView): template_name = "stationDataHTML.html" When I run, and I click the button to change the iframe content, I recevie and error Not Found: /data/stationDataHTML.html [02/Sep/2021 16:02:04] "GET /data/stationDataHTML.html HTTP/1.1" 404 6279 Is there a a way to change the iframe content to a locally hosted page? (stationDataHTML.html)
