How to retrieve data from an SQL database stored in Azure with a Django WebApp (both in the same Azure resource group)?
I am trying to develop a WebApp for my company where the users can visualize data that is stored in an SQL SERVER database in Azure using a Django webapp. I have been using pyodbc in the past to send the queries and retrieve the required data but was wondering if there was a better way like adding a REST API to the SQL DB or directly setting the DB as part of the Django databases. Both the Django WebApp and the SQL DB are in the same Azure resource group. Thanks for your help. -

how to insert additional model without losing data stored on mysql
My django app has two model, for example model_A and model_B, and this app could run well on docker. The docker compose is following version: '3.8' services: app: build: ...... volumes: ..... db: image:mysql5.7 volume: ....... nginx: image:.... volumes: volume_mysql: ....... After running the app for a while, I want to add a model, for example model_C on the app, exchanging app container to new one containing model_C. docker-compose stop docker rm app docker rmi app docker-compose up -d --build And makemigrations/migrate process also work without any error message docker exec app python manage.py makemigrations docker exec app python manage.py migrate On the other hand, I did not update the volume_mysql, because volume_mysql contained a lot of important data (I was reluctant to remove the volume, which resulted in loose all data) When I tried accessing model_c (on admin page), however, error_message 1146, "Table 'race_record.result_model_C' doesn't exist" was displayed. I guess it seem to be because volume_mysql is old, having yet to conntain ‘model_c’, although migrate process was done well. So, how to add model_c without losing date stored on mysql -

Efficient way to continuously consume messages from Redis Streams while being connected to Websockets through Django Channels
I have written a Django application to receive updates of long running tasks. I am using Redis as a channel layer for web-sockets and also making use of Redis Streams to store the updates of the tasks that are currently running. I have spawned a thread from connect method of WebSocket Consumer to run an infinite loop to continuously check for updates from Redis Consumer. This seems to be a hackish solution for what I am trying to achieve i.e. to remain connected to the websocket and also simultaneously receive updates from Redis Streams. This is my code for Websocket Consumer. As you can see, I am running an infinite loop to check for any new messages in the stream through Redis Consumer. import json from threading import Thread from asgiref.sync import async_to_sync from channels.generic.websocket import WebsocketConsumer from django.utils import timezone from redis import ConnectionPool, Redis from redis_streams.consumer import Consumer class ProgressStateConsumer(WebsocketConsumer): def __init__(self): self.task_id = self.task_group_name = None connection_pool = ConnectionPool( host="localhost", port=6379, db=0, decode_responses=True, ) self.redis_connection = Redis(connection_pool=connection_pool) self.messages = [] super().__init__() def connect(self): task_id = self.scope["url_route"]["kwargs"]["task_id"] self.task_id = task_id self.stream = f"task:{self.task_id}" self.task_group_name = ( f"task-{self.task_id}-{round(timezone.now().timestamp())}" ) async_to_sync(self.channel_layer.group_add)( self.task_group_name, self.channel_name ) thread = Thread(target=self.send_status) thread.start() self.accept() def … -

django strawberry query choice field values
I am using strawberry graphql for my project. I have a form field where I need to show options from my choice fields. I have a model like class Product(models.Model): REQUIREMENT_CHOICES = ( ("N", "New"), ("O", "Old"), ("M", "Maintained"), ) requirement = models.CharField( max_length=50, choices=REQUIREMENT_CHOICES, blank=True, ) Here in my graphql query how can I query REQUIREMENT_CHOICES without without making custom query to handle this. django-graphene would give options query easily. How could I do this in strawberry ? -
setting up Celery with RabbitMQ
I'm trying to set up Celery (5.2.7) with RabbitMQ (3.8.19) (Django 4.1.5) As a result, the task appears in the “celery” queue with the “Unacked” status, and after 30 minutes it goes into the “Ready” status with a message. "amqp.exceptions.PreconditionFailed: (0, 0): (406) PRECONDITION_FAILED - delivery acknowledgement on channel 1 timed out. Timeout value used: 1800000 ms. This timeout value can be configured, see consumers doc guide to learn more" When calling the method directly (without .delay), everything works correctly. I have no idea what is configured incorrectly running celery: $ celery -A mylocal worker -l info -------------- celery@DEV2 v5.2.7 (dawn-chorus) --- ***** ----- -- ******* ---- Windows-1 - *** --- * --- - ** ---------- [config] - ** ---------- .> app: mylocal:0x18205ade830 - ** ---------- .> transport: amqp://<RMQLogin>:**@<RMQ_HOST>:<RMQ_PORT>/<RMQ_VIRTUAL_HOST> - ** ---------- .> results: disabled:// - *** --- * --- .> concurrency: 12 (prefork) -- ******* ---- .> task events: OFF (enable -E to monitor tasks in this worker) --- ***** ----- -------------- [queues] .> celery exchange=celery(direct) key=celery [tasks] . myapp.tasks.send_spam_email Project structure: mylocal | -mylocal | - init.py - celery.py - settings.py -myapp | - templates | - myapp | - celery.html - admin.py - forms.py - models.py - … -

How do I embed a QR scanner pop-out upon clicking the QR camera icon?
I am trying to get a UI dialog window to display a QR code scanner upon clicking on the icon button for that corresponding row. Currently, when I click on the icon, nothing happens. I am unsure of how to display the QR scanner in the form of a dialog box. I am relatively new to element-ui and would greatly appreciate any inputs. {% block mainbody %} {% verbatim %} <div id="app2" class="container"> <div class="emr-table"> <el-table ref="multipleTable" :data="list" stripe style="width: 50%" @row-click="handle" @selection-change="handleSelectionChange"> <el-table-column prop="id" label="Index"> </el-table-column> <el-table-column prop="order_id" label="Order ID"> </el-table-column> <el-table-column prop="ward_number" label="Ward No."> </el-table-column> <el-table-column prop="qr" label="QR"> <template slot-scope="scope"> <el-button size="mini" type="warning" icon="el-icon-camera" circle @click="launchQR(scope.row)"> </el-button> </template> </el-table-column> </el-table> </div> </div> {% endverbatim %} <script> new Vue({ el: '#app2', data() { return { list: [] } }, mounted() { this.getemrList() }, methods: { getemrList() { // Obtain EMR list axios.post(ToDJ('emrList'), new URLSearchParams()).then(res => { if (res.data.code === 0) { console.log(res.data.data) this.list = res.data.data } else { this.NotifyFail(res.data.data) } }) }, // Success notification NotifySuc(str) { this.$message({ message: str, type: 'success' }) }, // Error notification NotifyFail(str) { this.$message({ message: str, type: 'warning' }) } } }) </script> {% endblock %}
