How can I access my static files from my Django app?
I have a Django app running in a Docker container. I am using Nginx to serve as the production server with a docker-compose file putting the app, Nginx and Postgres together in a network of containers. I set up my Dockerfile as follows: FROM python:3.9.6-buster ENV HOME=/home/app/ ENV APP_HOME=/home/app/web RUN mkdir -p "${APP_HOME}/staticfiles" # Create user ENV PYTHONBUFFERED=1 WORKDIR $APP_HOME COPY requirements.txt $APP_HOME RUN pip install -r requirements.txt COPY . $APP_HOME which as you can see sets a staticfiles directory. However, following normal Django principals my file structure is /home/app/web/quote_checklist/static/quote_checklist when I exec into the web container. I'm using the following in my settings.py BASE_DIR = Path(__file__).resolve().parent.parent STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, "staticfiles") When I access the index page I am getting an error that the directory/file /home/app/web/staticfiles/quote_checklist/css/base.css is not found, suggesting my app is looking in this staticfiles directory, which has nothing in it. I tried removing the /staticfiles/ bit from my static volume as well but then the system just looks in /home/app/web/static/quote_checklist/css/base.css rather than following the normal Django path, which would be to look in quote_checklist/static/quote_checklist/css/base.css. Does anyone have suggestions? -

Division between two annotations
I'm creating those two annotations as it follows: cs = Champion.objects.all() total_games = Match.objects.all().count() cs = cs.annotate( picked_games=Count( expression='participants__match__id', filter=Q(participants__role='BOTTOM'), distinct=True ), total_games=Value(str(total_games), output_field=IntegerField()) ) And everthing's alright until here. I fetch both the picked_games and total_games with correct results. >>> cs.get(name='Jhin').picked_games 27544 >>> cs.get(name='Jhin').total_games 97410 However, if i try to divide one by another: cs = cs.annotate( pick_rate=ExpressionWrapper( expression=F('picked_games') / F('total_games'), output_field=FloatField() ) ) This results on a 0: >>> cs.get(name='Jhin').pick_rate 0.0 I don't understand what's problem here.. I can get the result if divide them externally, so why can't i get the result on a different column for the whole queryset? >>> cs.get(name='Jhin').picked_games / cs.get(name='Jhin').total_games 0.28319474386613286 -

Requests to AWS using Django not using correct parameters on all files
I have a Django application that upon loading the admin, only receives 4 out of 6 of the necessary static files. The difference between the 4 successful and the 2 failed is that the following paramters are not present in the failed requests: X-Amz-Algorithm X-Amz-Credential X-Amz-Date X-Amz-Expires X-Amz-SignedHeaders X-Amz-Signature However the parameters are present in the request headers referer. Also it is consistently the same 2 files. And yes they exist as I will mention further down in this question. I installed django-storages and boto3 to work with AWS. Here are the relevant settings from settings.py: INSTALLED_APPS = [ ... 'storages', ... ] AWS_S3_ACCESS_KEY_ID = 'my-access-key' AWS_S3_SECRET_ACCESS_KEY = 'my-secret-access-key' AWS_STORAGE_BUCKET_NAME = 'my-bucket-01' AWS_S3_FILE_OVERWRITE = False AWS_DEFAULT_ACL = None DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' AWS_S3_REGION_NAME = 'eu-west-2' AWS_S3_SIGNATURE_VERSION = 's3v4' AWS_S3_ADDRESSING_STYLE = "virtual" A successful request: https:// my-bucket-01.s3.eu-west-2.amazonaws.com/admin/css/responsive.css?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=my-access-key%2F20220217%2Feu-west-2%2Fs3%2Faws4_request&X-Amz-Date=20220217T212138Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=31bc0e43fcc693f70c7662432ee6d88d8358652894611a0f7387ac35febf5ef9 A failed request: https:// my-bucket-01.s3.eu-west-2.amazonaws.com/admin/css/fonts.css Failed requests referer: https:// my-bucket-01.s3.eu-west-2.amazonaws.com/admin/css/base.css?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=my-access-key%2F20220217%2Feu-west-2%2Fs3%2Faws4_request&X-Amz-Date=20220217T212138Z&X-Amz-Expires=3600&X-Amz-SignedHeaders=host&X-Amz-Signature=af8fb82686dd0dcc2600eebdf9ceecec482dd44be02a3c3f3a9b793f96cee617 I went to the link in the referer and it worked. So my question is either: Why do only some of my requests include the correct parameters and how do I get them to use the correct ones? or How do I force the requests to use the referers? -
Filter urlencode with 2 Level reverse relationship
I have these models: class Issuer(models.Model): name = models.CharField() @property def investor_count(self): return Investment.objects.filter(offering__issuer_id=self.pk).count() or 0 def __str__(self): return self.name class Offering(models.Model): issuer = models.ForeignKey(Issuer, on_delete=models.CASCADE) name = models.CharField() def __str__(self): return self.name class Investment(models.Model): offering = models.ForeignKey(Offering, on_delete=models.CASCADE) name = models.CharField() def __str__(self): return self.name And I want to display in the Issuer list view the number of investments it has. This is the function I'm currently using, # link investments to page def view_investments_link(self, obj): count = obj.investor_count url = ( reverse("admin:crowdfunding_investment_changelist") + "?" + urlencode({"issuer__id": f"{obj.id}"}) ) return format_html('<a href="{}">{} Investment(s)</a>', url, count) view_investments_link.short_description = "NUMBER OF INVESTMENTS" And this is how it looks: But the line + urlencode({"issuer__id": f"{obj.id}"}) does not work. It changes my url to http://localhost:8000/app/investment/?e=1. Is there a way to filter Investments using the issuer_id? -

How to reload the current page when form was sent?
Hey, after the form was sent the page needs to be automatically reloaded / refreshed. Either just the current page is going to be reloaded or the variable slug_title (which would be part of the current page url) needs to be passed into the (' ') from HttpResponseRedirect. Do you have any suggestions? I would really appreciate it. :) views.py def posts(request, slug_titel): post = get_object_or_404(Thread, slug_titel=slug_titel) form = ThreadForm() if request.method == "POST": form = PostForm(request.POST) if form.is_valid(): form.save() return HttpResponseRedirect(' ') # <- here I need to put in slug_title from above -
How to add multiple values to checkbox field? Django
I am have a form with a checkbox field and hidden price field inside for loop like this: {% for item in inventory %} <input type="checkbox" name="item_name" id="{{forloop.counter}}" value="{{item.name}}"> <input type="hidden" name="item_price" value="{{item.price}}"> {% endfor %} But I also want to add item.price of the selected item to it. Basically I would like to get the data from views like this: item_name = request.POST.getlist('item_name') price = request.POST.getlist('price') Which would both have a list of chosen items. ['item name 1', 'item name 2'] ['item price 1', 'item price 2'] or together [['item name 1', 'item price 1']['item name 2', 'item price 2']] The second option would be better but I have no clue how to do that. Also I would like to add more values to it in the future. How do to do that? -
Listing objects field instead of Object in Django Rest Framework
I've got a model class Like(models.Model): product = models.ForeignKey('ProductInStore', on_delete=models.PROTECT) user = models.ForeignKey('users.CustomUser', on_delete=models.PROTECT) class Meta: unique_together = ('product', 'user',) and a serializer class LikeSerializer(serializers.ModelSerializer): user = serializers.PrimaryKeyRelatedField(read_only=True, default=serializers.CurrentUserDefault()) product = serializers.PrimaryKeyRelatedField(read_only=True) class Meta: model = Like fields = ('user', 'product',) class UserLikedProductsApiList(generics.ListAPIView): queryset = Like.objects.all() serializer_class = LikeSerializer And so if someone likes a product, adds it to favourites, it creates an Like object in database. And i want to create an endpoint users/me/likedProducts so that i can list all the products that self.user.request has liked. Meaning all the Like instances but instead of Like instances i want to show only Like.product instances. Lets say a person x has liked 4 items, and i want to show only 4 items in that list. Do you have any idea how to get around that in Django Rest Framework? -

Django apostrophe escaping change
While upgrading Django I noticed that the html escape function used to translate an apostrophe into &#39; whereas it now translates it into &#x27;. I understand the old value is the HTML code and the new value is the hex code. The change seems to have come about because Django used to do the translation itself but now hands it off to python's html module. My question is, are these functionally equivalent? Are there any case where I would need to worry about this change? Also, in case I am not asking the right questions, can anyone direct me to what I should read to understand why these 2 types of codes exist and how they are used? -

Django Image upload issue Cloundinary
i'm learning Django at present and just about getting to the deployment stage at hit a problem serving static/media with Cloudinary, following guides how to do this, it seems straight forward enough. I've checked the Cloudinary support but I can't find anything to help, just wondering if anyone has any input. The problem I have is that I am using Exiffield (to get image info) and ImageSpecField from ImageKit to resize the images for thumbnails and I think this is giving me problems with Cloudinary.

Secondly I get 400 Client Error: Bad Request for url: https://res.cloudinary.com/ **path to file*** when trying to open my site (which is being served locally and in development This is using ImageField as upload.

Django - Paypal Cancel Suscription
I recently used the django-paypal library in my project. All is working fine, the only problem I'm facing is that I don't find the way to implement a cancel button (to cancel a suscription) or an upgrade button (to change the suscription plan). There is no mention of those buttons in the documentation, so I guess I'm asking this question here to confirm that it can't be achieved with the django-paypal library -

Make select field toggle another field using Django Forms WITHOUT jQuery
How can I create a toggling behavior using Django form fields such as shown in the gif purely using Django?

In order to create the effect shown, I am using jQuery and some beginner Django code: <div class="col-md-5"> <label>Division </label> <select id="division" name="division" class="form-control select2"> {%for division, name in divisions%} <option value="{{ division }}">{{ name }}</option> {% endfor %} </select> </div> <div class="col"> <h3><strong>OR</strong></h3> </div> <div class="col-md-5"> <label>Center</label> <select id="center" name="center" class="form-control select2"> {%for center, name in centers%} <option value="{{ center }}">{{ name }}</option> {% endfor %} </select> </div> $(document).ready(function () { // Set option selected onchange $("#center").change(function () { // Set selected if ($("#division").val() != "None" && $("#center").val() != "None") { $("#division").val("None"); $("#division").select2().trigger("change"); } return; }); $("#division").change(function () { // Set selected if ($("#division").val() != "None" && $("#center").val() != "None") { $("#center").val("None"); $("#center").select2().trigger("change"); } return; }); }); However the rest of my fields are declared using django forms: class NewTitlesForm07(forms.Form): def __init__(self, *args, **kwargs): super(NewTitlesForm07, self).__init__(*args, **kwargs) self.fields['start_month'] = forms.ChoiceField(choices=MONTH_CHOICES, widget=forms.Select(attrs={'class': 'select2 form-control'})) self.fields['start_year'] = forms.ChoiceField(choices=YEAR_CHOICES_07, widget=forms.Select(attrs={'class': 'select2 form-control'})) … -
Set value of GeoDjango map widget in change form based on other field using jQuery

Processing a Django form
I have a problem using Django forms while learning Django and adapting code from a variety of online courses and examples. As a result, the code may be “messy” – but if I can get it to work the way I need, I can improve my coding style later. I wish to display a template that contains a form. Some of the data displayed in the page rendered in the template is read from one table/model, polls_CC_Questions, and I wish to write data input in the page into a related table, polls_CC_Resp_NoFK.
