use nginx to serve dynamically created media images in Django/React
I have a React front-end and a Django backend. I am also using nginx server. In the admin panel, I am able to add pdfs which go directly into a 'media' folder inside of the django application. In development, everything works correctly but In production, when Debug = false, the media files do not show up. I am thinking of using the nginx server to re-route to the media folder. But I think something is wrong, as the media files do not show up. Also, is this the best method to redirect to the media files? Below is my ngnix server server { listen 80; client_max_body_size 60M; location / { proxy_pass http://frontend:3000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; } location /api { proxy_pass http://backend:8000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; } location /admin { proxy_pass http://backend:8000/admin; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; } location ~^ /media { autoindex on; alias /path/to/media; } location /nginx-health-check { access_log off; return 200; } } -
TypeError at /formpage '>' not supported between instances of 'str' and 'int' also the error is specific in form.is_valid
This is forms.py from django import forms from django.core import validators def check_for_z(value): if value[0].lower() !='z': raise forms.ValidationError("NAME NEEDS TO START WITH Z") class FormName(forms.Form): name = forms.CharField() email = forms.EmailField() text = forms.CharField(widget= forms.Textarea) botcatcher = forms.CharField(required=False, widget=forms.HiddenInput, validators=[validators.MaxValueValidator(0)]) This is views.py from django.shortcuts import render from . import forms from .forms import FormName from django.http import HttpResponseRedirect def index(request): return render(request,'formapp/index.html') def form_name_view(request): form = forms.FormName() if request.method == "POST": form = forms.FormName(request.POST) if form .is_valid (): # do something code print("Validations scuces") print("NAME: "+form.cleaned_data["name"]) print("EMAIL: "+form.cleaned_data["email"]) print("TEXT:"+form.cleaned_data['text']) # return HttpResponseRedirect("/thanks/") else: form= FormName() return render(request,'formapp/form_page.html',{'form' : form}) Now actually it is throwing error on the line form.is_valid() and is showing TypeError at /formpage '>' not supported between instances of 'str' and 'int' And this is happening when I change/add attribute in the botcatcher i.e i add value='joke' Everything else is similar to normal django -
Are coding applications such are android app dev, normal django, python coding and some ethical hacking use many cores or a single core
I am planning to buy a pc, and I am confused between some parts because I don't know what type of hardware likes coding. Like a good 6 core 12 thread would be better, or an 8 core, 16 thread be better. If both are superior overpowered, Would a good 4 core machine with 8 threads do the work? -

Django Models inheritance and Serializers
I want to have several models inhering from NoticeModel but currently I only have one: class NoticeModel(SpicerModel): userId = models.ForeignKey( 'account.User', on_delete=models.CASCADE, null=False, blank=False, related_name='notice_user' ) is_read = models.BooleanField(null=False, blank=False, default=False) context = models.CharField(max_length=64, null=False, blank=False, choices=NoticeContext.CHOICES) message = models.CharField(max_length=255, null=False, blank=False, default='') class BookingRequestNotice(NoticeModel): booking_request = models.ForeignKey( BookingRequest, on_delete=models.CASCADE, null=False, blank=False, related_name='booking_event_notice' ) And here are the serialisers: class NoticeModelSerializer(serializers.HyperlinkedModelSerializer): userId = serializers.ReadOnlyField(source='userId.email') class Meta: model = NoticeModel fields = [ 'id', 'userId', 'is_read', 'context', 'message' ] class BookingRequestNoticeSerializer(NoticeModelSerializer): class Meta: model = BookingRequestNotice fields = NoticeModelSerializer.Meta.fields + ['booking_request'] To get all of the Notices, I do: class NoticeList(APIView): permission_classes = [permissions.IsAuthenticated] def get(self, request): user = getCurrentUser(request) notices = NoticeModel.objects.filter(userId=user).filter(is_read=False) serializer = NoticeModelSerializer(notices, many=True, context={'request': request}) return Response(serializer.data) The problem is that, since I am using NoticeModelSerializer I am only getting objects with the common fields (I do not get booking_request). How can I return the specific serializers without having to query each one of them individually? -
django template refresh causing session data loss
I am having a problem where I don't seem to be able to identify the root cause. I explain. I have a template where the user make a search and graphs and data make it to the page. From the query value that the user inputed, I need to pass it in a session to another template. here is what the view look like: @method_decorator(login_required, name='dispatch') class SupplierPage2(LoginRequiredMixin,APIView): def get(self, request, *args, **kwargs): query = request.GET.get('search_ress', None) print(query) context = {} #if query and request.method == 'GET': Supplier = supplier2.objects.filter(supplier = query) labels = Item2.objects.filter(fournisseur = query).values_list('reference', flat=True)[:10] labels = list(labels) default_items = Item2.objects.filter(fournisseur = query).values_list('number_of_sales', flat=True)[:10] default_items = list(default_items) label1s = Item2.objects.filter(fournisseur = query).values_list('reference', flat=True)[:10] label1s = list(label1s) default_item1s = Item2.objects.filter(fournisseur = query).values_list('number_of_orders_placed', flat=True)[:10] default_items1s = list(default_item1s) context.update({'Supplier' : Supplier, 'labels':labels, 'default_items':default_items,'label1s':label1s, 'default_item1s':default_item1s}) context2 = {'query':query} print("context",context2) request.session['query_dict'] = context2 return render(request, 'Supplier2.html',context) and here is what I get in the log when trying to query 'BOLSEI': BOLSEI context {'query': 'BOLSEI'} start 2020-11-11 14:32:10.714716 start 2020-11-11 14:32:10.715460 None context {'query': None} start 2020-11-11 14:32:20.765804 start 2020-11-11 14:32:20.766572 supplier name {'query': None} it works in a first time, as the query contains a value and all, but then when the … -
Django REST Framework | Ordering by Count from a ManyToMany Field
I'm following a Django REST Framework's Course, but I got stuck trying to set the ordering configuration from django_filters into a ViewSet. ordering = ('-members__count') In the original code of the Course, -members__count is used as query to return total members count, but when I try to use the same syntax I got this error: Error: Cannot resolve keyword 'count' into field. Choices are: auth_token, circle, created, date_joined, email, first_name, groups, id, invitation, invited_by, is_active, is_client, is_staff, is_superuser, is_verified, issued_by, last_login, last_name, logentry, membership, modified, password, phone_number, profile, user_permissions, username Maybe I'm misunderstanding this error, but all these suggested options correspond to Fields from my model. Also, in the Course its indicated that is a query representation format to get the total count of that field, so I'm a little confuse about that. Anyway, this is a resume of my code but you also can see my full detailed code in this repo in case to be required: https://github.com/cadasmeq/comparte_ride/tree/master/cride/circles.

How to annotate a queryset with time extracted from timestamp in seconds?
I have model with record_time field which is of IntegerField type. It stores timestamp in second (Unix epoch time). I need to annotate the queryset with time only which should be extracted from record_time. I came up with this so far annotated_qs = WorkerData.objects.annotate( time_e=datetime.fromtimestamp(F('record_time')).time() ) But this results in error (which make sense): an integer is required (got type F) How can I make this to work? -
Django: Ordering by last item in reverse ForeignKey relation
I'm trying to implement a qs.sort_by operation, but I'm not sure how to go about it. Given the following models class Group(models.Model): name = models.CharField(max_length=300) ( ... ) class Budget(models.Model): ( ... ) amount = models.DecimalField( decimal_places=2, max_digits=8, ) group = models.ForeignKey( Group, related_name="budgets", on_delete=models.CASCADE, ) Where each Group has either 0 or > 5 budgets assigned I am trying to sort a Group.objects.all() queryset by the amount of their last (as in, most recently assigned) Budget. I know that if it was a OneToOne I could do something like the following: Group.objects.all().order_by('budget__amount') With ForeignKey relations I was hoping I could do something like Group.objects.all().order_by('budgets__last__amount') But alas, that is not a valid operation, but I am not sure on how to proceed otherwise. Does anyone know on how to perform this sorting operation? (if it is indeed possible) -

How to decode SAMLResponse in Django View?
I am writing a view to create a user in project that has logged into another site. Whenever the user logins to that site he/she gets redirected to url:https://localhost:127.0.0.1:8000/auth/ad/reply/. The site sends me an SAMLResponse from which I want to extract the email address, firstname & lastname for the user. Following is my views.py and urls.py: views.py from django.shortcuts import render, redirect from django.http import HttpResponse from django.views.decorators.csrf import csrf_exempt # Create your

How to Remove Item In the Django Admin for ManyToMany Multiple Select
My Django admin interface is rendering a multiple select, reflecting a many-to-many relationship between Contact and Email. E.g. I can choose multiple emails per contact in the add Contact page. The emails are stored in a separate table that contains just the emails. From the admin interface is it possible to remove one or all of the emails from a Contact that is already created? Is it some setting/argument used in the email admin class? -

JQuery link onClick event sends image - how to get the link object instead?
I have a dropdown list with image and text on each link item. The data tags are on the link which wraps both text and image. When I click on the text, the jQuery.fn.init gives me the a.dropdown-item as I'd expect, but if the image gets clicked, it gives me the image object instead with the a.dropdown-item as parent. I thought I'd specified the filter correctly in the function call, but obviously not - can anyone point me in the right direction? Dropdown item contruct: <a class="dropdown-item" href="/i18n/setlang/" data-nextpage="/ca" data-languagecode="ca"> <img src="/static/ca.png" class="d-inline-block align-middle pb-1" alt="" loading="lazy"> &nbsp;Català </a> Script start: $(document).ready(function() { $('#languagelist a').on('click', function(event) { event.preventDefault(); let target = $(event.target); let nextpage = target.data('nextpage'); let url = target.attr('href'); let language_code = target.data('languagecode'); ..... I thought specifying 'a' would just give me the link object, but when the image is clicked that's what comes as target (without data tags obviously). Any help much appreciated :) -

How to create a queue for python-requests in Django?
REST API service has a limit of requests (say a maximum of 100 requests per minute). In Django, I am trying to allow USERs to access such API and retrieve data in real-time to update SQL tables. Therefore there is a problem that if multiple users are trying to access the API, the limit of requests is likely to be exceeded. Here is a code snippet as an example of how I currently perform requests - each user will add a list of objects he wants to request and run request_engine().start(object_list) to access the API. I use multithreading to speed up requests. I also allow retrying failed API requests via setting a limit on the number of requests for each request object upper_limit. As I understand there should be some queue for API requests. I anticipate there must be a more elegant solution for this, however, I could not find any similar examples. How can one implement/rewrite this for usage with Django? import requests from multiprocessing.dummy import Pool as ThreadPool N=50 # number of threads upper_limit=1 # limit on the number of requests for a single object class request_engine(): def __init__(self): pass def start(self,objs): self.objs={obj:{'status':0,'data':None} for obj in objs} done=False … -
Pass data from django view to Javascript file
I have table data in PostGreSQL which is easily accessed in my Django View. Now I want to pass this data to a javascript .js file whose purpose is to use this data and visualize using d3.js This is what I have tried as an example, but no luck views.py def view_function(request): data = 'test_data' return render(request, 'test.html', context = {'data':data}) test.html <head> </head> <body> <script src="{% static 'test.js' %}">myFunction({{data}})</script> </body> test.js function myFunction(view_data) { console.log(view_data); }
