Django Deployment on Heroku Issue
Folks I've been steadily working through error codes trying to deploy a Django app on Heroku since yesterday. Design/front end is more my skillset, and I'm struggling to get my head around it. I've worked through a lot of questions and fixes here that have got me further, but there's still something breaking the deployment, even though it says it's built and deployed. What else should I include in this post to help solve this issue? Many thanks in advance!

How can I handle multiple requests at the same time in Django?
I'm currently writing an API in which a user could transfer money from their account to a phone but I'm facing an issue which is the user can call the API more than once at the same time and ask for transferring the money. Normally the balance of his account wouldn't be correct after the calls so I searched a lot and found out that I can use atomic transactions and lock the database. Now if the user uses the API for example twice, one of them runs correctly but the other one gets django.db.utils.OperationalError: database is locked error. Any idea how can I handle both of them correctly? (I could use a while and wait until the database gets unlocked but I rather don't do that) models.py @transaction.atomic() def withdraw(self, amount, phone, username): property = transferLog.objects.filter(username=username).order_by('-time').select_for_update()[0] if property.property >= int(amount): self.username = username self.property = property.property - int(amount) self._from = username self._to = phone self.amount = int(amount) self.time = str(datetime.datetime.now()) self.save() return {'result': 'success', 'message': 'transfer complete', 'remaining': self.property} else: return {'result': 'error', 'message': 'not enough money'} -

Celery task has disabled backend until another task (from a different app) is imported
I'm having a problem with celery, redis backend in a django environment. When I import a celery task from one file the backend is DisabledBackend, and any calls to delay() hang/block. However when I import a celery task from another file, the backend is RedisBackend and any calls to delay() work fine. The weird part is that after importing the second task, the backend of the first task changes to RedisBackend and then works fine. See example below: >>> from file1 import task1 >>> task1.backend <celery.backends.base.DisabledBackend object at 0x7f2bf3582470> >>> from file2 import task2 >>> task2.backend <celery.backends.redis.RedisBackend object at 0x7f2bf2bc7668> # And now the very weird bit, the backend of task1 now is correct >>> task1.backend <celery.backends.redis.RedisBackend object at 0x7f2bf2bc7668> Both tasks are defined using the following construct from celery import shared_task @shared_task def task1(): # Logic here from celery import shared_task @shared_task def task2(): # Logic here I can't seem to find any reason why this might happen. When I inspect the celery log I see both tasks registered. - ** ---------- [config] - ** ---------- .> app: *redacted* - ** ---------- .> transport: redis://localhost:6379// - ** ---------- .> results: redis://localhost:6379/ - *** --- * --- .> concurrency: 2 … -

Django-rules makemigrations "No changes detected"
I'm using django-rules for object level security. I recently added a new field "managers" to my Location model, but python manage.py makemigrations doesn't detect it: No changes detected Given the following model: from django.db import models from django.conf import settings from django.contrib.auth.models import Group from rules.contrib.models import RulesModel # Create your models here.

Django form errors appearing without error
I made a research here in Stack and my problem is the opposite of the majority, I saw some ways to make it appear, but my problem is that it's appearing when the user hits the "Register" button / Refresh the register page.

How to pass onclick variable from javascript to django form
I am a beginner and I really need your help for a function. You have a table and when you click on a cell, it opens a form in a pop-up modal to enter some text called "trigramme". Then you select the "time" (corresponding to the row) and the "position" (corresponding to the column) on the pop-up form, submit it and it will put the text into the correct cell on the table. This works correctly. Now, I would like to take the "time/position" variables directly from the cell clicked and pass these variables to the django form, so that you only have to enter the text in the form and submit it. I have a function to pick up the time and position after clicking a cell that works to display the cell clicked position (column header related to this cell) and time (row header related to this cell) : $('table').on('click', 'td:not(:first-child)', function(e) { var time = e.delegateTarget.tHead.rows[1].cells[this.cellIndex], position = this.parentNode.cells[0]; alert([$(position).text(), $(time).text()]); }) I also have this function to display the modal that works correctly : $(function () { var cells = document.querySelectorAll('td:not(:first-child)'); cells.forEach((e)=>{ e.addEventListener("click", ()=>{ $.ajax({ beforeSend: function () { $("#modal-activity").modal("show"); }, success: function (data) { $("#modal-activity.modal-content").html(data.html_form); … -
Django, multiprocessing and python logging
I have a django view with a method that calls multiprocessing.Process() and I'd like to configure logging to write logs to separate file for each subprocess. I've read some examples in the Python logging cookbook which focus on multiprocessing and writing logs to a single file, but I want to write to separate files. So I'm trying to create a new logging instance within the child process. I've set logging to None in django settings (because I think this is only called once in setup()) and then applied a logging config under the multiprocessed method, like so - def run_upgrade(self, input_data, status): logger = logging.getLogger("parent") logger.setLevel(logging.DEBUG) formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s') # set the console handler ch = logging.StreamHandler() ch.setLevel(logging.DEBUG) ch.setFormatter(formatter) logger.addHandler(ch) # set the filehandler fh = logging.FileHandler(f'/var/log/example/{status.device}.log') fh.setLevel(logging.DEBUG) fh.setFormatter(formatter) logger.addHandler(fh) Within the modules that are imported, I've then called getLogger(parent.child) to get them to propagate back to the root logger. Is this the right approach? -
Extendend Django App System to a "module" system?
honestly, I am not totally sure if thats a suitable SO question but I thought I can most likely get insights or answers here from the community. We currently devlop a web application or rather an extensible framework on top of django (Version 3.1.5). We therefore also use reusable apps but we lack several features of "plain" django apps: Some require changes to the settings.py We want to share a certain level of configuration (we use django-constance for that) Each app may (or may not) bring other depdencies either as pip dependencies or other django apps that would need to be installed I know that django has a pretty opiniated approach and tries to strictly isolate what an app does and what is "site specific" and belongs to the settings.py. In our scenario, however, both models don't perfectly fit as we want to have several deployments of a subset of our apps which we want to manage automatically and so, we dont want to manually maintan a large set of settings.py files that also are very similar and share lots of code (which is against Django very natural DRY). Finally, we came up with the idea of "modules" which are … -
Django: Adding more code or a new database table
I don't know if anyone has been in this situation before.

Thanks in advance. -
How to check each key separately from a list in a loop without creating multiple loops. Which may have a KeyError etc
I wrote a code that takes 5 keys from API. The authors, isbn_one, isbn_two, thumbinail, page_count fields may not always be retrievable, and if any of them are missing, I would like it to be None. Unfortunately, if, or even nested, doesn't work. Because that leads to a lot of loops. I also tried try and except KeyError etc. because each key has a different error and it is not known which to assign none to. Here is an example of logic when a photo is missing: th = result['volumeInfo'].get('imageLinks') if th is not None: book_exists_thumbinail = { 'thumbinail': result['volumeInfo']['imageLinks']['thumbnail'] } dnew = {**book_data, **book_exists_thumbinail} book_import.append(dnew) else: book_exists_thumbinail_n = { 'thumbinail': None } dnew_none = {**book_data, **book_exists_thumbinail_n} book_import.append(dnew_none) When I use logic, you know when one condition is met, e.g. for thumbinail, the rest is not even checked. When I use try and except, it's similar. There's also an ISBN in the keys, but there's a list in the dictionary over there, and I need to use something like this: isbn_zer = result['volumeInfo']['industryIdentifiers'] dic = collections.defaultdict(list) for d in isbn_zer: for k, v in d.items(): dic[k].append(v) Output data: [{'type': 'ISBN_10', 'identifier': '8320717507'}, {'type': 'ISBN_13', 'identifier': '9788320717501'}] I don't know what … -
How to specify the SearchVector content manually in Django for Postgres?
Django supports the Postgres full-text-search using a SearchVectorField. The data has to be prepared using to_tsvector on the Postgres side which is done by the SearchVector function in Django: class SomeSearchableModel(PostgresModel): searchable = SearchVectorField() I need to populate this column with data not stored in other columns of the table. The default way to go would be: class SomeSearchableModel(PostgresModel): text = TextField() searchable = SearchVectorField() On every save: obj.searchable=SearchVector('text') # Column name to be read This application doesn't hold the searchable data in a usable format within the database. The content is prepared within some backend script. How do I provide the SearchVectorField content manually? Like: obj.searchable=SearchVector(some_processed_text) The PostgreSQL query part would be: INSERT INTO ... SET searchable=to_tsvector(...). Calculating the content in Postgres is no option. -
