Synchronize Django DB with Ionic Client
I have a model in my django project hosted on Google Cloud Projects. Which looks like the one below. class License(models.Model): PLATFORM_CHOICES = ( ("ios", "iOS"), ("android", "Android"), ) LICENSE_CHOICES = ( ("prod", "Production"), ("dev", "Development"), ) license = models.TextField() created_dt = models.DateTimeField(auto_now_add=True) expiration_dt = models.DateTimeField() license_type = models.CharField(max_length=11, choices=LICENSE_CHOICES) platform_type = models.CharField(max_length=7, choices=PLATFORM_CHOICES) I am using this model with a serializer to retrieve the data using an Ionic+Angular client. This license is used to activate a service, and this licenses change every X days. I do not want to check on every request whether the key is not expired or fetch the key everytime the service is being used. I want to save this key on local storage, and save automatically on local storage every time a new value is created or updated in the database. How can I make this possible? I am trying to avoid to do something like this: this.sharedService.getLicense().subscribe(licenses => { var todaysDate = new Date(); licenses.map(license => { if (this.platform.is('ios') && todaysDate <= new Date(license.expiration_dt)) { this.licenseKey = license; } }); }) Any ideas will be much appreciated. -
Django Rest Framework Datatables DELETE
Issue I would like to send a list of ID's to the Django Rest Framework API url (which is the rest_framework routers default). So far everything is working up to the point of sending the ID's. When I click the delete button the DELETE call goes to 127.0.0.1:8000/api/entries/_id_/ and does not add the proper ID's that are selected for deletion. Error Message From Server I'm sure this was more or less obvious: {detail: "Not found."} detail: "Not found." entry_list.html {% extends "dashboard/base.html" %} {% load i18n %} {% block content %} <style> table.dataTable tbody tr.odd.selected { background-color:#acbad4 } table.dataTable tbody tr.even.selected { background-color:#acbad5 } </style> <!-- Page Heading --> <div class="d-sm-flex align-items-center justify-content-between mb-4"> <h2 class="text-gray-800">{% block title %}{% trans "Imported Entries" %}{% endblock %}</h2> <a role="button" class="btn btn-success" href="{% url 'import' %}"><i class="fas fa-plus-circle"></i> Import New Entires</a> </div> <button id="countbutton">Count rows</button> <button id="deletebutton">Delete rows</button> <!-- Content Row --> <div class="row"> <div class="col-md-12"> <table id="entrytable" class="table-hover table display table-bordered" align="center" style="width:100%"> <thead> <tr role="row"> <th>id</th> <th>date</th> <th>amount</th> <th>price</th> <th>fee</th> <th>entry_type</th> <th>reg_fee</th> <th>transaction_id</th> <th>trade</th> <th>symbol</th> <!-- <th>created_by</th>--> </tr> </thead> </table> </div> </div> {% endblock %} {% block js %} <link rel="stylesheet" type="text/css" href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.5.2/css/bootstrap.css"/> <link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.22/css/dataTables.bootstrap4.min.css"/> <!--https://datatables.net/examples/server_side/select_rows.html--> <!--<link rel="stylesheet" type="text/css" … -
Django Websockets Data going to the wrong Socket
Using Django Websockets + Channels, I create a (One) group and the message back and forth works just fine. Lets call this Group A The problem starts when I open a SECOND group and a SECOND (Lets call this group B) WebSocket connection in a different browser. The messages that I am trying to send to group A (first WebSocket connection), are going to group B (second WebSocket connection). All the messages that belong to group A go to the second WebSocket and the group B messages also go to the second socket. Here's my consumer.py import json from asgiref.sync import async_to_sync import logging LOG = logging.getLogger(__name__) from channels.generic.websocket import WebsocketConsumer, AsyncWebsocketConsumer class EventConsumer(AsyncWebsocketConsumer): async def connect(self): self.id = self.scope['url_route']['kwargs']['id'] self.group_name = f'enl_events_log_{self.id}' # Join room group await self.channel_layer.group_add( self.group_name, self.channel_name ) await self.accept() async def disconnect(self, close_code): # Leave room group await self.channel_layer.group_discard( self.group_name, self.channel_name ) # Receive message from WebSocket async def receive(self, text_data): # text_data_json = json.loads(text_data) # message = text_data_json['message'] # Send message to room group await self.channel_layer.group_send( self.group_name, { 'type': 'send.message', 'message': "Message received" } ) # Receive message from room group async def send_message(self, event): message = event['message'] # Send message to WebSocket await … -

Django: Annotate with field from another table (one-to-many)
Good day. I wish to annotate my model with information from a different table. class CompetitionTeam(models.Model): competition_id = models.ForeignKey('Competition', on_delete=models.CASCADE, to_field='id', db_column='competition_id') team_id = models.ForeignKey('Team', on_delete=models.CASCADE, to_field='id', null=True, db_column='team_id') ... class Team(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=30) teamleader_id = models.ForeignKey('User', on_delete=models.CASCADE, to_field='id', db_column='teamleader_id') ... class Competition(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=30) ... Looping through my competitions, I wish to retrieve the list of competitionteam objects to be displayed with the relevant team's name. I tried: CompetitionTeam.objects.filter(competition_id=_competition.id).filter(team_id__in=joined_team_ids).annotate(name=...) -where instead of the ellipses I put Subquery expressions in. However, I'm unsure of how to match the team_id variable. eg. *.anotate(name=Subquery(Team.objects.filter(id=competitionteam.team_id)).values('name')) Related is the question: Django annotate field value from another model but I am unsure of how to implement that in this case. In that case, in place of mymodel_id, I used team_id but it only had parameters from the Team object, not my competition team object. I didn't really understand OuterRef but here is my attempt that failed: CompetitionTeam.objects.filter(competition_id=_competition.id).filter(team_id__in=joined_team_ids).annotate(name=Subquery(Team.objects.get(id=OuterRef('team_id')))) "Error: This queryset contains a reference to an outer query and may only be used in a subquery." -
