Django/Python additional parameter causes internal server error

Is set a param for CharField like upload_to param for FileField possible?
I have a WorkOrderUploadFile model like bellow: class WorkOrderUploadFile(models.Model): wo_num = models.CharField(max_length="16") filepath = models.CharField(max_length=128, default="images/qiyun_admin_servicemanage_workorder/") file = models.FileField(upload_to=generate_files_directory) ctime = models.DateTimeField(auto_now_add=True) uptime = models.DateTimeField(auto_now=True) You see, for the FileField there is a upload_to param, so I can use the generate_files_directory method to generate the file field value. Is is possible to set a method for CharField param? (because the wo_num CharField is need use a method to generate the number.) -

Rendering/Redirecting Django in AJAX Success function
Trying my best to understand more between Django and Ajax but now I'm having a problem how to use (or what to use) between render to window.location.url in the ajax function. This is something along the lines of this similar question. To put it simply my situation is this: I'd like to pass a json to Django view so I used AJAX. "POST" Then from the url passed in AJAX it goes to view_routes view. I know that AJAX is expecting a response data so what I know is using HTTPResponse Problem: I want to pass routes (Objects) and routes_geojson (JSON) to the url where it will redirect to an HTML Page. (So I can use routes normally with {%%} tags and routes_geojson for its own purpose.) The said HTML page will also use view_routesviewif I usewindow.location.href = url`. How can I pass it from ajax? Use another ajax now with type:"GET"? Am I on the right track? Also if you have a suggested reading particulary on AJAX and Django that would be nice. :) Thank you! def view_routes(request, query=None): routes = None if query is None: routes = Route.objects.all() else: #View: Routes in Queried Boundary if request.method == 'POST': … -

Strange GET requests to my site
In the last days, Google Analytics is showing me some strange GET methods that have been requested on my website. I have no clue if it is done by robots or humans or if it is some kind of attack or something harmless. It is coming from different countries, which for me is even more confusing because it seems like it is not only one person/robot. Some examples of these urls are: /en/?lipi=urn:li:page:d_flagship3_feed;ipLRICUhTrGXGdPXnW0tnQ== /en/?lipi=urn:li:page:d_flagship3_feed;3kcVPzepRVGxY7MZjonjig== /en/?lipi=urn:li:page:d_flagship3_feed;mFWFR+VMS0SHqJTkYN87EA== /en/?_sm_pdc=1&_sm_rid=7MV6JrjR5MSrPHJMDDrtjMMQZVz6lqJrH02kZVk Does anybody has an idea what that is? -

Role of kafka consumer, seperate service or Django component?
I'm designing a web log analytic. And I found an architect with Django(Back-end & front-end)+ kafka + spark. I also found some same system from this link:http://thevivekpandey.github.io/posts/2017-09-19-high-velocity-data-ingestion.html with below architect But I confuse about the role of kafka-consumer. It will is a service, independent to Django, right? So If I want to plot real-time data to front-end chart, how to I attached to Django. It will too ridiculous if I place both kafka-consumer & producer in Django. Request from sdk come to Django by pass to kafa topic (producer) and return Django (consumer) for process. Why we don't go directly. It looks simple and better. Please help me to understand the role of kafka consumer, where it should belong? and how to connect to my front-end.

Using https as standard with django project
I am learning django and trying to complete my first webapp. I am using shopify api & boilder plate (starter code) and am having an issue with the final step of auth. Specifically, the redirect URL -- it's using HTTP:// when it should NOT and I don't know how to change it.. #in my view def authenticate(request): shop = request.GET.get('shop') print('shop:', shop) if shop: scope = settings.SHOPIFY_API_SCOPE redirect_uri = request.build_absolute_uri(reverse('shopify_app_finalize')) #try this with new store url? print('redirect url', redirect_uri) # this equals http://myherokuapp.com/login/finalize/ permission_url = shopify.Session(shop.strip()).create_permission_url(scope, redirect_uri) return redirect(permission_url) return redirect(_return_address(request)) Which is a problem because my app uses the Embedded Shopify SDK which causes this error to occur at the point of this request Refused to frame 'http://my.herokuapp.com/' because it violates the following Content Security Policy directive: "child-src 'self' https://* shopify-pos://*". Note that 'frame-src' was not explicitly set, so 'child-src' is used as a fallback. How do i change the URL to use HTTPS? Thank you so much in advance. Please let me know if I can share any other details but my code is practically identical to that starter code -
