Present Python variable in HTML Template in Django
I have a value extracted from JIRA API showing a total for a particular project. When I print the value, I can see the correct values and these are clearly being stored in the variable. # Emergency Changes Query jira_emergency_changes = jira.search_issues('labels = new-emerging-audit AND resolution = Unresolved').total # Open Issues Query jira_open_issues = jira.search_issues('project = UTILITY AND status = Open').total # Open JIRA Ticket Total Query jira_open_tickets = jira.search_issues('project = "UTILITY" AND status not in (Closed, Completed, Resolved) ORDER BY created DESC').total I want to add these values to a template page in a <p> tag, but no matter what method I try, it just doesn't render. Could some advice? :) -

Django custom admin filter: get filtered queryset before the current filter itself is applied

Django ORM filter model where all relation have value equals to
Lets say that I have two models: class Worker(models.Model): name = models.CharField(max_length=100) class Task(models.Model): worker = models.ForeignKey(Worker) name = models.CharField(max_length=100) I would like to retrieve all workers where ALL tasks are called "dig".

I've tried using filter and exclude with Q, like this: Worker.objects.filter(task__name='dig').exclude(~Q(task__name='dig')) But it didn't work, it don't remove those that have only one task like that. I could iterate over worker and tasks to find it, but is there any way to make this query using only orm? -

Django channels + Postgresql: Real-Time Database Messaging
I am currently developing an app with Django and PostgreSQL. Often, new information is sent to database (sometimes one time a day, sometimes over 30000 times a day). I have an UI (vue.js) and I want to see the data from the database showing to the client in real time. Currently I am using Django Channels. I implemented websocket and used psycopg2 library to listen to notifications from postgresql triggers. My consumer looks like this: class WSConsumer(WebsocketConsumer): def connect(self): self.accept() #the whole table is sent to the client after the connection self.send(json.dumps(ClientSerializer(Client.objects.all(), many=True).data)) #connecting to database conn = psycopg2.connect(dbname='...', user='...') conn.set_isolation_level(psycopg2.extensions.ISOLATION_LEVEL_AUTOCOMMIT) curs = conn.cursor() curs.execute("LISTEN update_clients_table;") #then I listen to any new data in this table and send it to the client while True: if select.select([conn],[],[],5) == ([],[],[]): print("Timeout") else: conn.poll() while conn.notifies: notify = conn.notifies.pop(0) print("Got NOTIFY:", notify.pid, notify.channel, notify.payload) message = notify.payload self.send(message) def disconnect(self): self.close() This is an example of handling changes in 1 table. I have 20 tables in total, and around 100 clients that can connect to the websocket. My question: is it a good way of building real-time app with Django and PostgreSQL? Is it simple, convenient, secure? Are there other ways to build … -

What is the best practice to store big sparse matrices in a django project?
I am finishing a public transport project that is using Dijkstra's algorithm. The algorithm is using adjacency matrices, with amount of nodes exceeding thousands -> propably going to scale this 10-100x, my matrices are sparse - <10% of non-zero values. The data is supposed to be updated once a day and is read-only. Since each of these values are evaluated multiple times per search, right now, I store non-zero values in the database, then create a matrix and save it as json file(n-lists of n-values), which is open and read every time the algorithm is run. What is the best practice to store and load this type of data? Should I store non-zero values the same way and just create sparse matrices with numpy and save it as HDF5 files? Would the HDF5 files introduce reading latency? I would like the final project to consist of 20-50k nodes, grouped into 1-5k matrices for each city and to be able to withstand something along the lines of a search a second. -

Django filter qs contains filename not working with underscores
my goal is to filter if the name of an uploaded document contains a search (a simple string from an input field submitted by the user). Strangely this works for long substring but not for short ones. Example My filter query is the following: Tab.objects.filter(document__file__icontains=search) where Tab is in simplest form a Model class like: class Tab(models.Model): name = models.CharField(max_length=50) and Document is another Model class wit a relation to Tabs and a file field. class Document(models.Model): tab = models.ForeignKey(Tab, on_delete=models.CASCADE) file = models.FileField(upload_to=custom_location) Weird behavior I've uploaded a file called example_test_123.pdf and if my search = example_test or test_123.pdf it results in a hit like expected. However, if search = test the filter doesn't find the file. Is this behaviour known or am I missing something here? Is it possible that the built-in name file is doing some trouble? Thanks.
