Django, how to save a randomly generated variable for the next session after POST method
I have an integer in Views.py which is generated randomly. I send it to Index.html: return render(request, 'index.html', {'number':number}) Then I have a simple form in forms.py class AForm(forms.Form): information = forms.CharField(label='Your answer', max_length=100) And this form in Index.html with POST method: <form action="{% url 'index' %}" method = POST> {% csrf_token %} {{ form }} <input type="submit" value="Submit"> </form> which leads to the same page and function. And I want to return via this POST method that number which I previously sent, because now it is already another, taken randomly, because it is the same function. But I already need the previous one. In other words I generate a random number and I need to save it for the next loading, after POST Method. I would even not send that number anywhere if it is possible. Is there a simple, elegant way to do it? I've read about sessions in Django, probably it is the way, but is there an easier way? Thanks. -

I want to create an alert to delete users with sweetAlert, but in the script tag when I create my url from a variable passed as a parameter in the function, the result is only the name of the variable to display and not its value function delInscPart(id){ var url = "{% url 'suppPartners' " +id+" %}" Swal.fire({ "title":"Etes vous sure de vouloir supprimé l invité ?", "text":"Si vous confirmer cette opération, Vous supprimerais cette invité !", "icon":"", "showCancelButton":true, "cancelButtonText":"Anuller", "confirmButtonText":"Je confirme", "reverseButtons":true, }).then(function(result){ if(result.isConfirmed){ window.location.href = url console.log(url) } }) } <td><a href= "#" onClick="delInscPart('{{list.user_inscrit.username}}');"><i data-feather="trash-2"></i>Supprimer</a></td> the result is {% url 'suppPartners' +id+ %} instead {% url 'suppPartners' admin %} -
PyCharm: Cannot connect to postgres-db in docker container
as the title says, I'm having trouble to connect a rather simple database-configuration with my IDE PyCharm. docker-compose.yml db: restart: always image: postgres container_name: db volumes: - postgres_data:/var/lib/postgresql/data/ environment: - POSTGRES_USER=postgres - POSTGRES_PASSWORD=postgres - POSTGRES_DB=postgres ports: - "5432:5432" networks: - db-net Using it with django, here are my database-settings from the backend, which are working perfectly fine: settings.py DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", "NAME": "postgres", "USER": "postgres", "PASSWORD": "postgres", "HOST": "db", "PORT": 5432, } } But when trying to connect the database inside PyCharm with the following settings, I'm getting this error: Note: The field for password was of course filled -> get's cleared everytime someone hits Apply or tries to test the connection. Does anyone might know what I'm doing wrong or maybe had the same problem? Thanks for your help and have a great weekend! -
How Can I Check if Date is Passed from Django Model
I am really new in Django and I want to check if Date Stored in Model is passed.

How to loop websocket events in django in a roulette game
Hello fellow programmers, I'm currently using Django with WebSockets to create a replica close to https://bloxflip.com/roulette or any kind of online synchronized roulette you can have that involves multiple bets from all different players. I am at this stage attached image, and I'm trying to create a backend loop that will run between states (Waiting for bets, Calculating hashes, Rolling, Restarting), the only solution I got is using workers from Celery that will loop it on a Redis server. I wonder if there is any other solution that can help me make this loop in the backend so I can send it to the frontend with WebSockets. Let me know what other method i can use or if i can improve my actual code. consumers.py class RouletteConsumer(WebsocketConsumer): def connect(self): self.room_group_name = 'roulette' async_to_sync(self.channel_layer.group_add)( self.room_group_name, self.channel_name ) self.accept()` current_state = states[0] self.send(text_data=json.dumps({ 'type':'current_state', 'current_state': current_state })) def receive(self, text_data): text_data_json = json.loads(text_data) bet_data = text_data_json['bet_data'] async_to_sync(self.channel_layer.group_send)( self.room_group_name, { 'type':'send_bet', 'bet_data': bet_data, } ) def send_bet(self, event): bet_data = event['bet_data'] self.send(text_data=json.dumps({ 'type':'bet', 'bet_data': bet_data })) def current_state(self, event): state = event['current_state'] self.send(text_data=json.dumps({ 'type':'state', 'current_state': state })) -
How to store token from another api in Django?
In my DJango application I use another API external to my application. To authenticate on the external API, I must first make a POST with my credentials, and get a JWT token. Once this token is retrieved, I have to put it in the headers to be able to make requests on the api. Once the token is retrieved (thanks to requests), how to store it in a "global" way to be able to reuse it until it expires ? -
Store the primary key but display the name of an instance in Django Forms
I created a form through which the user can send an email to customers. I wanted to create a UI where the user can select a customer from the list of customers and automatically after clicking the customer, the email field is updated(i.e., the customer's email). I have done this before and the Foreign Key relation works the best but in this case, I think there is no need to create a different app for Email support and then give the foreign relations, etc. forms.py: class EmailForm(forms.Form): customer = forms.CharField(widget=forms.Select) email = forms.CharField(max_length=100) subject = forms.CharField(max_length=100) attach = forms.FileField() message = forms.CharField(widget = forms.Textarea) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['customer'].widget.choices = [(i.name, i.name) for i in Customer.objects.all()] email.html: {{ customer_data|json_script:"customerdata" }} <script type="text/javascript"> var customerdata = JSON.parse(document.getElementById('customerdata').textContent); document.getElementById('id_customer').onchange = function(event){ var cust = customerdata.find(({customer_id}) => customer_id == event.target.value); document.getElementById('id_email').value = cust && cust.email ? cust.email : ""; }; I am passing the Customer data to the email.html using JSON but I am not able to assign the email to the appropriate field because id_customer returns a String, i.e., The customer name and not the customer_id as I want. I understand that I am purposely displaying the customer_name instead of … -
Django.urls reversing urls through multiple url pattern lists within one app
I have a url.py inside my project which includes the following urls.py (belongs to my app). urls.py from django.urls import path,include from .views import Index, Foo bar_urlpatterns = [ path('foo/', Foo.as_view(), name='foo'), ] urlpatterns = [ path('', Index.as_view(), name='index'), path('bar/', include(bar_urlpatterns)),] I'm trying to outsource the subpaths of a path. The docs says the function include can include a pattern_list and when i call the url"http://myurl/foo/bar" directly, this seems to hold true. I can also load the view via ajax directly when i give it the string. But when i try to use the reverse {%url 'foo'} url template tag this throws: Uncaught SyntaxError: Invalid regular expression flags(at ...) Doing the same thing with non-outsourced url patterns works perfectly fine for me. The html elements where i use the function: <a onclick="load_tab_view({% url "foo" %})">Foo</a> <div id="tab_view_replaceable"></div> js (works fine with my other views) function load_tab_view(url){ replace_id = 'tab_view_replaceable'; $.ajax({ url: url, type: 'GET', dataType: 'html', success: function(data){ $('#'+replace_id).html(data); } }); } Is there a way in which im still able to outsource my subpaths and make use of the reverse url template tag? (I dont want to create a new app for bar) -
Celery scheduler not performing the task
I was trying to use Celery to query an external api at a regular frequency and update my database in my Django project with the new data. Celery schedules the task correctly and sends it to the celery worker but it never executes anything.

How to apply lookups in django filter query according to conditions?

Fail to enable Smartsheet webhook (502 Bad Gateway)
Django: 4.0.6 Smartsheet Python SDK: 2.105.1 Ngrok: 3.0.6 I have a Django server running on localhost, forwarded my localhost through Ngrok, have setup a callback route for accepting/responding to the Smartsheet-Hook-Challenge, and created a webhook instance using Python SDK. However, when I try to enable my webhook by running the following (documented here): Webhook = smartsheet_client.Webhooks.update_webhook(webhook_id,smartsheet_client.models.Webhook({'enabled': True})) Ngrok immediately returns 502 bad gateway, and my webhook instance's disabledDetails attribute becomes Request returned HTTP status code 502 (ref id: wtegm9). And I have no clue what's the cause of this 502. PS: While I'm writing this question, I was able to successfully enable my webhook using cURL command, so I can go ahead and start working. But enabling the same webhook instance with update_webhook python method still gives 502. Since updating webhook with cURL worked, could it be a bug in the Python SDK method itself? -

Django pull list of all users, but shows list of multiple users with only current users credentials

Django.db.models.field.CharField
I have a Django project that I'm trying to cobble together for a very basic survey that needs to be entered for demographic information. I've dummied up some data through the admin site in order to get my ListView working for the time being. Unfortunately I'm getting a strange response. I built the models.py to be a drop down of a full spelled out and then to keep it small, I've made the actual storage in the db 1-3 characters. When I get my list view, one that uses 1 character to store for gender presents as (<django.db.models.fields.CharField>,), I would like for it to present as as the larger name of "Male", "Female", "Non-binary". However for my race and ethnicity fields which are 2 & 3 characters, those are returning as the actual storage for the DB (i.e, 'AA', 'NHP'). I'm more comfortable with SQL, so I'm not opposes to adding a table for a key as there would only be 11 entries for now, but its possible that more things could be added down the line. models.py: from django.db import models from django.contrib import admin from django.contrib.auth.models import User # Create your models here. class StuData(models.Model): id_num = models.IntegerField(primary_key=True) …
