How to run an url in views in Django?
I have a PDF uploading form. When a user sends this form I want to trigger a URL in my views. I want the invoked URL address to be opened only once in the backend. The user cannot view this page. The reason I want this is that the API I call from here enables me to do another process. How can I run an URL in my views backend? views.py def upload_pdf(request, id): if request.method == 'POST': customer = get_object_or_404(Customer, id=id) form = PdfForm(request.POST, request.FILES) if form.is_valid(): new_pdf = form.save(commit=False) new_pdf.owner = customer new_pdf.save() name = new_pdf.pdf.name.replace(".pdf", "") url = 'https://api..../perform/{0}'.format(name) return redirect('ocr', id=new_pdf.id) else: form = PdfForm() customer = get_object_or_404(Customer, id=id) return render(request, 'upload_pdf.html', {'form': form, 'customer': customer}) -
How to add custom Header in Authlib on Django
I would need some of your help adapting Authlib with Django. I'm trying to develop a Django app using OpenId and Authlib to connect my users and facing an issue with the access token, the issue invalid_client occurs. Using Postman I found out that the OpenId provider needs some parameters in the Header like 'Content-Length' or 'Host'. When the Header param is defined in client.py, it works like a charm. However, I'd like to pass the custom header from views.py (mostly to avoid defining the Host directly in the package), but authorize_access_token doesn't allow multiple arguments, def auth(request): token = oauth.customprovider.authorize_access_token(request) Maybe the "Compliance Fix for non Standard" feature might help, but I wasn't able to adapt it for Django and the Header parameter https://docs.authlib.org/en/stable/client/oauth2.html#compliance-fix-oauth2 from authlib.common.urls import add_params_to_uri, url_decode def _non_compliant_param_name(url, headers, data): params = {'site': 'stackoverflow'} url = add_params_to_uri(url, params) return url, headers, body def _fix_token_response(resp): data = dict(url_decode(resp.text)) data['token_type'] = 'Bearer' data['expires_in'] = int(data['expires']) resp.json = lambda: data return resp session.register_compliance_hook( 'protected_request', _non_compliant_param_name) session.register_compliance_hook( 'access_token_response', _fix_token_response) Does anyone know a way to pass a custom Header to Authlib or defining it using the Compliance Fix and Django? Thank in advance ! -

Is there a way to display the extra forms at the top when using django InlineModelAdmin instead of the bottom after all the existing forms?
Am using inlines(InlineModelAdmin) in my django Admin interface to make it easier to edit the models of the Parent model. However, by default, the extra forms for models appear at the bottom. The problem is that there may be a lot of previous records such that you have to scroll to the bottom to add a new record. Is there a way to change this default behavior such that the new extra forms appear at the top? -

Is there a way to run django constantly on the server to update a database based on live data
I am developing a virtual stock market application on django and came upon the following problem. In any stock market application, there is an option of limit buy, stop loss and target sell. This essentially means to buy a share if it ever touches a price which is lower than the current price, to sell a share if it touches a very low price and to sell a share if it touches a high price respectively. For this, the server needs to constantly monitor the live data coming in from the API of a particular stock and perform the action if it happens. However, during this time no one may be making any requests on the site so how do I get django to monitor the prices of the stocks every 5 seconds or so to check if the order needs to be executed or not? -

How to set read only property to entire Django forms based on session user
I have created a form that can be used to update/create/view records. When a user selects a record that record data is rendered in the form. So that user will able to view/edit the form. The problem statement here is that if a record is created by some other user then the session user will not able to edit (only the creator should have access to edit). I am thinking to write a logic so that when the record is created by the session user then only he/she will edit. Otherwise, the user will just view the record using the same form. Below is my view file current_blog = Blog.objects.get(pk=blog_id) init_dict = { "blog_title": current_blog.blog_title, "blog_description": current_blog.blog_description, "last_modified": current_blog.last_modified } form = NewBlog(initial=init_dict) return render(request, "myblog/blog.html", {"new_blog": form}) form.py class NewBlog(forms.Form): blog_title = forms.CharField(label="Form Title", max_length=250, widget=forms.TextInput( attrs={"class": "form-control", "placeholder": "Enter title here"} )) blog_description = forms.CharField(label="Blog Description", widget=forms.Textarea( attrs={"class": "form-control", "placeholder": "Enter blog Description"} )) blog.html {% for field in new_blog %} <div class="col-sm-12"> <fieldset> {{ field.label }} {{ field }} <div class="text-danger">{{ field.errors }}</div> </fieldset> </div> {% endfor %} -

I am implementing user authentication in my first Django app. I decided to follow a tutorial from here. I just finished the implementation, and it happens that when I add the following route path('api/app', include('app.urls')),to the url.py, I get the following error, which crashes t he platform: .... File "/Users/frankydoul/opt/anaconda3/lib/python3.8/site-packages/django/urls/resolvers.py", line 123, in _check_pattern_startswith_slash if regex_pattern.startswith(('/', '^/', '^\\/')) and not regex_pattern.endswith('/'): RecursionError: maximum recursion depth exceeded while calling a Python object Removing it let the platform running. Is anybody familiar with the error please ? -
