webscoket fails to connect after few successful connections in react application
I am using django channels to implement real time updates to react frontend. But the problem is after few successful connections from frontend with websocket, the connection drops and gives two different kind of error in firefox (can't establish connection to ws://url) and chrome (failed to connect due to unknown reason). But the connection works for the first few times but with time this error occurs. Below is the socket connection code in client-side. export default function Comment(props) { const socket = new WebSocket(`${WEBSOCKETURLCOMMENT}${props.reqID}/`); const socketLike = new WebSocket(`${WEBSOCKETURLLIKE}${props.reqID}/`); ........... const socketOpen = () => { console.log('Socket opened', 'mrlog'); } const syncWebsocketData = (e) => { try { let recData = JSON.parse(e.data); if (recData?.c) { setComm(recData.c[props.index].comments) setLoading(false) } } catch (error) { console.log('Error to parse'); } } useEffect(() => { socket.addEventListener('open', socketOpen) socketLike.addEventListener('open', socketOpen) socketLike.addEventListener('message', syncWebsocketData) socket.addEventListener('message', syncWebsocketData) return function cleanup(){ socketLike.removeEventListener('open', socketOpen) socket.removeEventListener('open', socketOpen) socketLike.removeEventListener('message', syncWebsocketData) socket.removeEventListener('message', syncWebsocketData) socket.close() socketLike.close() } }, []) ....... It works fine at first but after some udpates it can' connect anymore. -
Django query on event list: finding most recent events
I have a django model that collects events. It looks roughly like this: class Events(models.Model): class EventType(models.TextChoices): OPEN = ... CLOSE = ... OTHER = ... READ = ... user = models.ForeignKey(User, on_delete=models.CASCADE) box = models.ForeignKey(Box, on_delete=models.CASCADE) event_timestamp = models.DateTimeField(default=django.utils.timezone.now) event_type = models.CharField(max_length=6, choices=EventType.choices) Events occur when users do things with boxes. I have four very related queries I want to do, and I'm not at all sure how to do this without resorting to SQL, which usually isn't the right solution with django. For box B and user U, is the user most recently open or closed for this box? For Box B, how many users are in an open state? For Box B, I'd like to plot day by day how many users are open, so I'd like to get a grouped array of users who opened and closed on each day. I'd like a table over all boxes of how many users are in an open state. For example, in SQL these would have forms something like this (not tested code, I'm hoping it's easier to use django's query language): -- 1 SELECT event_type FROM Events WHERE event_type in ('OPEN', 'CLOSE') AND user = U HAVING max(event_timestamp); … -
Why does COUNT(*) in my SQL query return several values? How to get one single value for total rows found?
I have a Django class getting some order data from a PostreSQL database. I need to get the number of rows found in a query. Trying to get the found rows count from the following query with COUNT(*): sql = """SELECT COUNT(*) FROM mbraindb.sysmanufacturingorders o LEFT JOIN mbraindb.sysmanufacturingorderrows r ON o.manufacturingorderID = r.manufacturingorderID AND r.Enabled <> 0 left join ( select si.salesitemid, si.externalsalesid, p.productarticlenumber, p.productname from mbarticlemanagement.syssalesitems si join mbarticlemanagement.syssalesitemproducts ip on si.salesitemid = ip.salesitemid join mbarticlemanagement.sysproducts p on ip.tableid = p.productid group by si.salesitemid, si.externalsalesid, p.productarticlenumber, p.productname ) as salesitems on r.salesitemid = salesitems.salesitemid left join ( select r.manufacturingorderid, r.quantity, p.productarticlenumber, p.productname from mbraindb.sysmanufacturingorderrows r join mbarticlemanagement.sysproducts p on r.productid = p.productid group by r.manufacturingorderrowid, r.manufacturingorderid, r.quantity, p.productarticlenumber, p.productname order by r.manufacturingorderrowid asc ) as products on o.manufacturingorderid = products.manufacturingorderid %s GROUP BY o.manufacturingorderID, o.manufacturingorderCustomer, o.manufacturingorderOrgOrderID, o.Enabled, o.manufacturingorderDate, o.manufacturingorderFinishdate, o.manufacturingorderStatus, o.manufacturingorderIdentifier, coalesce(salesitems.externalsalesid, ''), coalesce(salesitems.salesitemid, 0) ORDER BY o.manufacturingorderFinishdate ASC, o.manufacturingorderOrgOrderID ASC, o.manufacturingorderID ASC;""" % (sqlwhere) When I print the result from the query above, I get a lot of data: [RealDictRow([('count', 256)]), RealDictRow([('count', 4)]), RealDictRow([('count', 32)]), RealDictRow([('count', 2)]), RealDictRow([('count', 32)]), RealDictRow([('count', 2)]), RealDictRow([('count', 9)]), RealDictRow([('count', 1)]), RealDictRow([('count', 1)]), RealDictRow([('count', 1)]), RealDictRow([('count', 1)]), RealDictRow([('count', 4)]), RealDictRow([('count', 4)]), RealDictRow([('count', 4)]), RealDictRow([('count', … -
Django get min and max value from PostgreSQL specific ArrayField holding IntegerField(s)
I have an ArrayField in my model holding IntegerFields. I'm looking for the best way in which I can extract the smallest and the biggest integer out of this array. The Django documentation doesn't give examples of something similar and I wonder if the right way would be finding out how and if I can use aggregation function on this ArrayField or if I can cast this to normal python list of integers somehow and use the build in min, max functions? Any suggestions for performing this would be helpful. Examples even more. -
How to handle Django model objects being saved concurrently?
Given I have the following Django model: class Details(models.Model): id = models.BigAutoField(primary_key=True) data = models.TextField() more_data = models.TextField() Now I have a celery task which is Updating data field of the model and rest API calls updating more_data field. Currently I have written within celery functions as: model_obj.data = data model_obj.save() and function called from API call as: model_obj.more_data = more_data model_obj.save() Now since the both functions can execute simultaneously for given id, it is possible that data might not be saved correctly. So, if I update above functions to : model_obj.data = data model_obj.save(update_fields=[data]) and model_obj.more_data = more_data model_obj.save(update_fields=[more_data]) will it work fine ? -
Retrieve Auth Code From URL Python \ Django
Devs, Im working with the SmartSheet API and it requires me to go out and pull a authroization code to establish a token for a session. Im able to to redirect to their link, than be redirected to my app in Django with the AUTH code in the URL. Here is my setup so far. Here is my View @login_required def SmartSheetAPI(request): record = APIInformation.objects.filter(api_name="SmartSheet").first() if record == None: print('Authorization Token Doesn't Exist In DB, Fetching New Token!') return redirect("https://app.smartsheet.com/b/authorize?response_type=code&client_id={}&scope=READ_SHEETS%20WRITE_SHEETS&state=MY_STATE".format(client_id)) So If you visit the following page on my app, it checks if a auth token exists in the database, if it doesnt exist than go out to the redirect and authorize it. I get dumped back to my app with the URL code in the URL to this view. The example is this on the return http://127.0.0.1:8000/api/smartsheet/smartsheetapiauth?code=123456789&expires_in=599905&state=MY_STATE I need to extract code. def SmartSheetAPIAuth(request): return render(request, 'smartsheetapiauth.html') -

Would it be a bad idea to use Django template tags to add context to a template? (Trying to imitate ease of Vue components)
One of the problems I have with Django (at least how I've learned to use it so far) is that there's not a great way to build components like in Vue. In my templates I have been using {% include %} statements to include more modular pieces of template code/components. the problem, though, is that if I use a piece of data in the component then it needs to be passed to every single view that I use it in. For example, suppose I have this template: <p>I'm a template!</p> {% include './components/weather.html' %} and then in ./components/weather.html: <p>The weather is {{ weather.status }} today.</p> Now, in any view that I want to use weather.html in, I will need to pass in 'weather' as a context variable. It would be better if I could just include a template in another template and know that it will automatically make the database requests needed to populate the context it needs. Is there any reason I can't use a tag for this? Like instead of {{ weather.status }} use {% weather %} and then in template tags something like: @register.simple_tag def weather(): return weather.get_status() Is this going to open up some vulnerability I … -
Syntax error when writing {% load static %} when trying to load an image

Using Django for communication between APIS?
I am new in the world of programming. I know a little python and i am learning Django. I understand that Django is very useful for webpages backend. But I don't just want a website or an webapp. What I want is to centralize all the operations of my company by communicating through APIS different applications such as CRM (costumer relationship management), SQL database, bulk mail software, etc. For example, I want that when I perform an action in my CRM software (sales), it activates a scrapy script that I am creating, which scrapes certain pages, and then stores information in my SQL database. Can I centralize all of this through Django as if it were a central base that connects all my scripts and the communications between APIS? -

Django form with redirect that is callable on each page
I have a search box that can redirect the user to several pages, based on the input. When i m put the searchbox on 1 specific page called "zoek", it works fine: def zoek(request): if request.method == "POST": form = SearchForm(request.POST) if form.is_valid(): q = form.cleaned_data["SearchQuery"] for result in util.list_entries(): if q.capitalize() == result: return HttpResponseRedirect(reverse("entry", args=[result])) return HttpResponseRedirect(reverse("searchresults", args=[q])) return render(request, "encyclopedia/zoek.html", { "form": SearchForm(), }) However, I want to put this searchform in a sidebar that is included on every page. The sidebar is constructed in a base called layout.html: {% load static %} <form action="{% url 'index' %}" method="post"> {% csrf_token %} {{ searchform }} <input type="submit" value="search"> </form> But I cannot return redirects on the layout. I tried using a custom context processor, but found out those are not suited for this. How could I make sure this form functions on every page that extends layout.html? -
What can slow down an ajax call?
I know I might get slammed for this because I cannot give a case that others might duplicate. However I have a problem and being fairly new to ajax I don't know where to turn I am using ajax to fire a django GET and the django response is almost instantaneous, the ajax function takes about 2 seconds to fire views.py class NewBoard(View): @staticmethod def get(request, board_selector): context={} print('NewBoard') return JsonResponse(context, safe=False) script.js function getNewBoard(board_selector) { setWaitCursor('wait') $.ajax( { type: "GET", url: 'new-board/'+board_selector, cache: false, success: function () { console.log('x') displayBoard(); } } ); console.log('a') setWaitCursor('default') } function displayBoard() { console.log('c') } When this runs, 'NewBoard' and 'a' appear in some fast sub-second time, but 'x' and 'c' do not appear until about 2.5 seconds later. I have other similar functions that work perfectly. Maybe I am doing something fundamentally wrong, but if not where can I start to look for a way to speed this up? -
