Django char field with choices list
So, I want to implement a char field with choices list. The idea is that it looks like a common char field but when you click on it and start typing something in, a dropdown menu pops up and you can choose something (also it sorts choices depending on what user types in). How do we do that? -
Can't get LightSlider (JQuery) working in my Django application
For a website I am creating I want to add a slider/carousel using LightSlider (JQuery). For some reason it is not working and I can't figure out what the problem is. I tested if JQuery is working and it is. Thereby I tested the code outside of Django, so only with HTML, CSS, JS, JQuery, and it worked. What am I doing wrong?

Adding an item to a chart in django - Attribute Error
I am working on my first django-project and I am trying to build an e-commerce website from scratch. I tried to write a logical flow for adding an item to my chart but somewhere I'm mistaken. It continuously raises an error that I do now know how to handle. In models.py I created the model for an item that will be added to the chart and it'll be displayed on the chart.html page. models.py class UserItem(models.Model): name = models.CharField(max_length=50, blank=True, null=True) price = models.FloatField(blank=True, null=True) img = models.ImageField(upload_to='gallery', blank=True, null=True) quantity = models.IntegerField(default=1) prod_id = models.ForeignKey(to=ComputerScienceProducts, on_delete=models.CASCADE, blank=True, null=True) def add_item_to_cart(self, prod_id): prod = ComputerScienceProducts.objects.get(pk=prod_id) try: existing_prod = UserItem.objects.get(prod) existing_prod.quantity += 1 existing_prod.save() except: new_prod = UserItem.objects.create(name = prod.name, price=prod.price, img=prod.img) new_prod.save() In views.py, the logic I tried to implement in coding lines is: If the user clicks the button "add to chart", will be sent through a GET method the pk of the product he wants to add on his or her chart. From that point, I look for the product that has that PK in the database. Then I check whether the product is already in the cart and if so, I just increase the quantity by 1, … -
Stuck on "Waiting for (domain)..." after submitting form in django application
I have a simple django application that has a 'contact' page where the user can submit a form directed to my gmail account. The form works fine when I run it on localhost on my computer, but when running on my linux server, my browser gets stuck on "Waiting for (domain name)..." after I click submit, and the page just sits there (no errors, just stuck on 'waiting') Since it works locally. I have a feeling it has something to do with my server (ubuntu running apache), but this is my first time managing a server and I'm lost.

Django Filter Forms: How Can I Use Buttons As Replacement For Multple Choice
I am filtering using ModelMultipleChoiceFilter but i don't like the way it looks so i want to use buttons instead of the default widget and i don't want to use checkboxes either. I have seen this done before so i just need to know how to actually do it. Is there a way to use buttons as multiple choice instead of the default widget where you have to press CTRL to select multple choices from the list? Is there a way to maybe create a custom widget or some work around?

docker containers on the same net (from compose) don't see each other

Why pytz.localize and datetime.replace return different results?
As documentation of pytz says: def localize(self, dt, is_dst=False): '''Convert naive time to local time''' if dt.tzinfo is not None: raise ValueError('Not naive datetime (tzinfo is already set)') return dt.replace(tzinfo=self) So as the last line shows, localize and dt.replace are the same. Because the algorithm above, if we remove the if part, is return dt.replace(tzinfo=self) which just use datetime.replace. But we know that the output are different: time = datetime.now() tehran_tz = pytz.timezone('Asia/Tehran') print(tehran_tz.localize(time)) print(time.replace(tzinfo=tehran_tz)) Output: 2021-02-22 21:15:29.781400+03:30 2021-02-22 21:15:29.781400+03:26 It's not about which one is correct which is discussed here. But why they are different while their code are the same. -

Django: How To Pass List Of Arguments Through URL
![enter image description hereI am trying to create a search page where buttons can be clicked which will filter the posts like in this page Splice Sounds (i think you need an account to view this so ill add screenshots). To do this i think i need to pass a list so that i can filter by that list but i can't find a way to do this. having a GET form for each genre (which is being created by a for loop) would allow me to filter by one genre at a time but i want to filter by multple genres at once so that won't work in the site that i linked to: they pass the genres/tags into the url so how could i do this in django? Also: i could make seperate url paths and link to those but then i would have to do this for every combination of genres/tags which would be too much so i can't do that. here is some relevant code: this is how i want to filter which is why i need to pass a list of args for arg in args: Posts = Posts.filter(genres=arg) -
How to make one view from one app be shown in all urls in Django?
I have created an app for the main template of my project (All other templates inherit from this one). The template includes header, footer and an aside in which i can add and delete posts from the admin panel. Now, when rendering all the templates everything (header, footer and the respective {% block content %}) is shown correctly but not the aside because i'm not passing any url to the view managing it. I'm trying to pass that view to every URL of my project so the aside is always shown. I just dont get the way of doing it. Just to clarify: Following the code i'm going to show now the aside is shown in localhost:8000 only. Not in localhost:8000/inicio nor any other url.

How to match a list with a dict and time related values
I got this in my views.py # Get the amount of kilo attached to products product_data = {} for product in ProductSpy.objects.all(): product_data[product.id] = {"product_id": product.product_id, "kilo": product.kilo} # Get quantity bought of each product total_qty_bought = self.order_item_model.objects.values("product").annotate(Sum("quantity")) So in my product_data dump I got this here: 6: {'product_id': 32, 'kilo': Decimal('25.00')}, and in my total_qty_bought dump I got this: {'product': 32, 'quantity__sum': Decimal('5')}, Now as the product_id match the product, I want it to return 125, as we got 5 times the quantity of 25 kilo. In my total_qty_bought dump you'd find id's not relevant, so if they dont match any in my product_data dump, I want them ignored. How can I achieve this smartest? print dump: product_data: {4: {'product_id': 30, 'kilo': Decimal('25.00')}, 5: {'product_id': 31, 'kilo': Decimal('25.00')}, 6: {'product_id': 32, 'kilo': Decimal('25.00')}, 7: {'product_id': 33, 'kilo': Decimal('25.00')}, 8: {'product_id': 37, 'kilo': Decimal('15.00')}, 9: {'product_id': 38, 'kilo': Decimal('15.00')}, 10: {'product_id': 39, 'kilo': Decimal('10.00')}, 11: {'product_id': 40, 'kilo': Decimal('10.00')}, 12: {'product_id': 41, 'kilo': Decimal('5.00')}, 13: {'product_id': 42, 'kilo': Decimal('2.50')}, 14: {'product_id': 43, 'kilo': Decimal('5.00')}, 15: {'product_id': 44, 'kilo': Decimal('2.50')}, 17: {'product_id': 50, 'kilo': Decimal('2.50')}, 18: {'product_id': 51, 'kilo': Decimal('5.00')}, 19: {'product_id': 52, 'kilo': Decimal('10.00')}, 20: {'product_id': 53, 'kilo': … -
