Creating Dynamic Form Fields in Django ModelForm
I am looking to search the instance, check a value in a specific field and then return a list for the field to Meta but it doesn't appear the __init__ can return anything. How can I make a dynamic form that based on a value in a field, shows only a predetermined other fields. Goal: Ultimately if subgrade_02_weight != None then make subgrade_02_title, subgrade_02_weight, subgrade_02_1_star, etc. visible. I have over 100 fields that I would need to make visible and do not want to do this in a hack way in the template. It seems like JS is the best approach but I have 0 experience in JS. class Inspection_ResultForm(forms.ModelForm): #work on this tomorrow def __init__(self, user, *args, **kwargs): super( Inspection_ResultForm,self).__init__(*args, **kwargs) #if user.groups.filter(name='Operations Manager').exists(): fields_list = ["subgrade_00_title", "subgrade_00_weight", "subgrade_00_1_star", "subgrade_00_2_star", "subgrade_00_3_star", "subgrade_00_4_star", "subgrade_00_5_star", "subgrade_01_title", "subgrade_01_weight", "subgrade_01_1_star", "subgrade_01_2_star", "subgrade_01_3_star", "subgrade_01_4_star", "subgrade_01_5_star" ] if self.instance.inspection_request.sample.order.specification.subgrade_02_weight != None: fields_extends = ["subgrade_02_title", "subgrade_02_weight", "subgrade_02_1_start", "subgrade_02_2_star", "subgrade_02_3_star", "subgrade_02_4_star", "subgrade_02_5_star"] fields_list.extend(fields_extends) print(fields_list) fields = fields_list return fields class Meta: model = Inspection_Result fields = ('subgrade_00_title', 'subgrade_01_title',) #would like this to be equal to field list calculated in __init__ -

Django on button click open modal and populate the form
I have a modal which contains a HTML form with customer details. On button click I want to get the details for the customer from view, open the modal and populate the details in the modal <td><a href="/edit_customer/{{ customer.customer_name }}" class="btn btn-primary" data-toggle="modal" data-target=".bd-example-modal-lg"><i class="fa fa-fw fa-edit"></a></td> It opens the modal but does not calls the function in view. I tried this way <td><a href="/edit_customer/{{ customer.customer_name }}" class="btn btn-primary edit_btn"><i class="fa fa-fw fa-edit"></a></td> By handling everything in js $(".edit_btn").click(function(){ var _url = $(this).attr('href'); $.ajax({ url: _url, success: function(response){ //show the modal //populate the form document.getElementById("customer_name).value = ""; ... }, error: function(error){ console.log(error) } }); }); But I don't want to do this way. I want to to populate in template only. Something like this - <form> <label>Customer Name:</label> {{ customer.customer_name }} <br> </form> Is it possible? -

Requests in Vuejs returning different response than Postman from django-rest-framework backend
I have been trying to implement the Twitch user authorization code flow. I am working on getting the authorization url generated from the django backend and pass it to my Vue front end so the user can open the user authorization page. Postman recovers the generated url perfectly however when i try to do the same in Vue using Requests it is giving me an entirely different object. Object { _events: {…}, _eventsCount: 1, _maxListeners: undefined, uri: {…}, method: "POST", readable: true, writable: true, explicitMethod: true, _qs: {…}, _auth: {…}, … } auth.js:37:12 and here is what Postman returns "{'url': 'https://id.twitch.tv/oauth2/authorize', 'client_id': 'xxx', 'redirect_uri': 'http://localhost:8000/api/twitch/callback', 'grant_type': 'token', 'scope': 'user_read'}" I'm not sure what could be causing this.

Many to many relationship does not work with django-safedelete as i want
I am using a library called django-safedelete to avoid permanently deleting records from the database, the technique is called "safedelete". Here is the documentation of the library https://django-safedelete.readthedocs.io/en/latest/managers.html I have a problem and it is that when I softdelete a record in the intermediate table between Actor and Film (Participation) the QuerySet ignores it completely, I mean when I execute a query to know in which film an actor has been, the Queryset ignores that the intermediate register that links the actor and the film is softdelete and shows in any case the films in which the actor has participated. here is an example of what happens: >>> Actor.objects.get (pk = 1) <Actor: Actor object (1)> >>> Film.objects.get (pk = 1) <Film: Film object (1)> >>> Participation.objects.all_with_deleted (). Values ('id', 'actor', 'film', 'deleted') <SafeDeleteQueryset [{'id': 1, 'actor': 1, 'film': 1, 'deleted': datetime.datetime (2021, 9, 4, 0, 43, 50, 125046, tzinfo = <UTC>) }]> >>> Actor.objects.get (pk = 1) .films.all () <SafeDeleteQueryset [<Film: Film object (1)>]> As you can see, it ignores that the participation record is softdelete and also shows the film in which the actor participated, what I need is not to show that the actor participated in that … -

How can I execute ModelAdmin.save_model asynchronously?
A Django-based website I'm building may occasionally need to run shell commands when initiated by an administrative user. Anticipating this, I decided it would be a good idea to write these processes to be asynchronous considering asyncio supports shells right out-of-the-box. I am executing these processes from the save_model() function of ModelAdmin, not an async view. My issue is when long-running processes are executed, the supposedly 'async' server gets completely hung-up on them and doesn't answer any other requests from clients until they are finished. I'm 100% certain this is because I'm running these processes in a sync function, albeit asynchronously (see below). I need to be able to tell the administrative user if the process they are running has succeeded or failed. I'm currently doing this through the messages API provided by Django. Here is the function executing the shell commands (Linux): import asyncio import sys async def run_subprocess(cmd: str) -> Tuple[int, bytes, bytes]: """Run a subprocess command asynchronously. Notes: This will execute the subprocess in a shell under the current user. Args: cmd (`str`): The command to run. Returns: exec_info (`tuple`): `(retcode, stdout, stderr)` from the subprocess for processing. """ # Create an execute the future try: proc … -

Django-Storages with SFTP: GET-requests fail
I a trying to use django-storages to access my "Hetzner" Storage Box (https://www.hetzner.com/storage/storage-box) using SFTP which should hold media data, i.e. image files which users of my website can upload dynamically. The corresponding part of my settings.py file looks like: DEFAULT_FILE_STORAGE = 'storages.backends.sftpstorage.SFTPStorage' SFTP_STORAGE_HOST = 'username.your-storagebox.de' SFTP_STORAGE_ROOT = '/media' SFTP_STORAGE_PARAMS = { 'username': 'username', 'password': 'password', 'allow_agent': False, 'look_for_keys': False, } The strange thing is that, when the user uploads an Image, it is placed on the storage space as I can confirm using SFTP. But getting the images from the storage box fails, no Image is displayed. An excerpt from the console: [03/Sep/2021 22:34:01] "GET /media/filename.jpg HTTP/1.1" 404 1962 I could figure out that Django is still looking inside my MEDIA_DIR for the files. Againg, the corresponding part of my settings: MEDIA_DIR = 'media' MEDIA_ROOT = os.path.join(BASE_DIR, MEDIA_DIR) MEDIA_URL = '/media/' So in a nutshell: Using SFTP seems to be working for putting files into storage, but getting them again somehow fails. I am hoping for some help. Thanks in advance! -
Django Celery broken after moving secret key to environment variable
I'm working on a Django project that uses Celery for periodic tasks. For improved security, I moved Django's SECRET_KEY into an environment variable. The app ran fine, so Django was certainly able to find the environment variable and set the SECRET_KEY. But an unexpected side effect was that all the regularly occurring Periodic Tasks stopped triggering. I was able to run the tasks manually from Django Admin, so the Celery workers were still alive and well, but the tasks wouldn't trigger themselves like they usually do. The app settings and Celery config are both located in a directory called server. Here's the file structure: -server -__init__.py -celery.py -settings.py Before moving the secret key, it was in settings.py like this: SECRET_KEY = "secret" After moving to an environment variable, the line in settings.py was like this: SECRET_KEY = os.environ.get("SECRET_KEY") And here's the contents of celery.py, in case that's relevant: os.environ.setdefault("DJANGO_SETTINGS_MODULE", "server.settings") app = Celery("server") app.config_from_object("django.conf:settings", namespace="CELERY") app.autodiscover_tasks() As soon as I moved the secret key out of the environment variable and back into settings.py, the tasks started firing again. I'm hoping to figure out why moving the secret key broke the periodic tasks so I can move the secret key back … -
Django Migrations stuck after executing in incorrect order
I made two changes to different models in my database. The first operations = [ migrations.DeleteModel( name='Settlement', ), ] And the second: operations = [ migrations.RemoveField( model_name='invoice', name='settlement_deducted', ), migrations.RemoveField( model_name='invoice', name='settlement_supporting', ), ] The issue is that they ran in this order, and the second one failed. The field being removed in the second migration uses the "Settlement" model, but since that model was deleted in the first migration it throws this error: ValueError: The field invoices.Invoice.settlement_deducted was declared with a lazy reference to 'accounting.settlement', but app 'accounting' doesn't provide model 'settlement'. The field invoices.Invoice.settlement_supporting was declared with a lazy reference to 'accounting.settlement', but app 'accounting' doesn't provide model 'settlement' Now when I try to do anything to fix it, it seems to just be stuck in that error state and continuously throws that same error. I have tried reverting the first migration to the previous migration on that model, adding that model back in and running makemigrations and then migrate so that the Settlement model exists again, and deleting the second migration (though it was never run anyway). All of these options are still throwing the same error. I am surprised that Django didn't catch this dependency issue … -
Reportlab in Django Application error - Forbidden (CSRF token missing or incorrect.)
I come from more of a data science background, but for fun I have been building a web application. I am new to django, javascript, and HTML, and it's a lot to wrap my head around - so if my coding appears unconventional I apologize. Feel free to offer any feedback. Within my application, I am trying to create a button on a webpage that does the following: Reads data input from an HTML table entered by the user in JavaScript (as an array). Using ajax, sends the data to a Python view. There, a function will be performed on the array, and the output will be returned to the user as a PDF generated by the reportlab library. Unfortunately, I continue to get the following error: Forbidden (CSRF token missing or incorrect.): /get_custom_bingo Here is the full error: Forbidden (CSRF token missing or incorrect.): /get_custom_bingo [03/Sep/2021 16:07:17] "POST /get_custom_bingo HTTP/1.1" 403 2513 [03/Sep/2021 16:07:17] "POST /pages/custom_bingo.html HTTP/1.1" 200 4320 [03/Sep/2021 16:07:17] "GET /static/JS/scripts.js HTTP/1.1" 304 0 I have tried to get it to go away, but nothing I can find online seems to be helping my current scenario. Does anybody know how to resolve this? (See the relevant sections … -
