Chromedriver not opening Django development server
I am formulating my first tests with Selenium and Chromedriver. I kept getting a NoSuchElementException in my test results. I tried to using an explicit wait but it timed out. I noticed that Chrome was raising ERR_FILE_NOT_FOUND so I made the path more explicit in my driver.get(file_uri()). Chrome found the html but was displaying my pure Django code instead of the generated html. If the development server was being launched properly I believe my test would be passing but I have no idea why it's not functioning as expected. Here is my test: class WebpageTests(unittest.TestCase): def test_title(self): driver.get(file_uri("network/templates/network/index.html")) open_form = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.ID, "new-post"))) open_form.click() form = driver.find_element_by_id("post-view") self.assertTrue(form.is_displayed()) if __name__ == "__main__": unittest.main() here is my setup: from sqlite3 import Timestamp from xxlimited import foo from django.test import Client, TestCase from .models import Post, User from selenium import webdriver import os import pathlib import unittest from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from selenium.webdriver.common.by import By def file_uri(filename): return pathlib.Path(os.path.abspath(filename)).as_uri() driver = webdriver.Chrome() Thank you in advance for your help! -
Django how to save User Model?
Good day again, so I have a form and a user can add multiple titles. Each submit will create a new object which includes the written title and the user who wrote it(submitted the form). I tried it with this but I don't know what to add in NewTitle.objects.create(title=title, ...) \views.py def title_view(request): try: profile = request.user.newtitle except NewTitle.DoesNotExist: profile = NewTitle(user=request.user) if request.method == 'POST': form = NewTitleForm(request.POST, instance=profile) if form.is_valid(): title = form.cleaned_data["title"] NewTitle.objects.create(title=title) #in the () I have to add the user= aswell return redirect('/another') else: form = NewTitleForm(instance=profile) return render(request, 'test.html', {'form': form, 'profile': profile}) \models.py class NewTitle(models.Model): user = models.OneToOneField( User, default=None, null=True, on_delete=models.CASCADE) title = models.CharField(max_length=200) I am working with basic User model. Currently, a user can submit the form and a new object will create just with the given title but without the user who wrote it because I just added title=title and not user=... Any ideas? -
Out of memory: Killed process (gunicorn) on AWS Lightsail
I am hoping someone can give me some direction on how to determine what is causing this out of memory to continue to occur. I am a novice in this arena, so any help will greatly be appreciated. I have a Django app using Gunicorn, Ngnix, PostgreSQL. I am also using Supervisor to monitor the app. If I reboot the sever it restarts the app automatically...no issues. The app was built using Flask prior to this and I never experienced this issue. Both apps had the following AWS: AWS Lightsail 512 MB Memory 1 Core Processor 20 GB SSD Disk 1 TB Transfer* Here are lines from the gunicorn error log: [2022-01-20 02:06:15 +0000] [723] [INFO] Booting worker with pid: 723 [2022-01-20 02:06:15 +0000] [724] [INFO] Booting worker with pid: 724 [2022-01-20 02:06:15 +0000] [725] [INFO] Booting worker with pid: 725 [2022-01-20 07:43:42 +0000] [708] [CRITICAL] WORKER TIMEOUT (pid:723) [2022-01-20 07:49:11 +0000] [708] [CRITICAL] WORKER TIMEOUT (pid:724) [2022-01-20 07:49:11 +0000] [708] [CRITICAL] WORKER TIMEOUT (pid:725) [2022-01-20 02:49:11 -0500] [724] [INFO] Worker exiting (pid: 724) [2022-01-20 02:49:11 -0500] [725] [INFO] Worker exiting (pid: 725) [2022-01-20 07:49:11 +0000] [708] [WARNING] Worker with pid 723 was terminated due to signal 9 [2022-01-20 07:49:11 … -

Django get primary key with JSON response

Django embed/dispaly .pdf in page
I am attempting to display .pdfs that have been uploaded by users. I can display the path to the pdf but not document itself. I attempted to use "" in the template but this is not working.

How to check for duplicate records in a Django admin inline?
How do you do perform validation checks involving multi-inline forms in Django admin inlines? For example, I have a simple Parent/Child model, with an admin interface showing the children in an inline table on the parent's admin change page. Each child has a "name" field which must be unique. On child model, I've implemented a clean() method to enforce this rule, raising a forms.ValidationError so the error is displayed in a user-friendly fashion in the admin UI. This method is called from the model's full_clean() method, which is called by Django admin during the validation step for each inline form. So, individually, if the user attempts to create a child record, that check caches the error. However, since Django runs the validation for each inline table separately before saving the records, it doesn't cache duplicates in the new data. So if the user creates two new inline rows and enters duplicate names in each of those rows, they pass the validation check, but then when Django goes to actually save the records, it encounters the exception, which is now handled like a very user-unfriendly 500 error. Is there an easy way to fix this? Looking through Django's code, I'm not … -
Restrict access to files from users except the superuser Django
I'm currently writing an app with Django and I want to restrict access to private files (except superuser). My files are served on Nginx For now, all the files request comes to the Django app and if the user has the right permission it will redirect to the Nginx to serve the file with the "X-Accel-Redirect" set in the Response: if user_has_right_permission or request.user.is_superuser: response = HttpResponse() response['X-Accel-Redirect'] = path return response else: raise PermissionDenied() These files need user authentication and to access each file user should send the token in the request header. The problem is when the superuser in the admin panel wants to download files got 403 Forbidden. because the token is not set in the request header. Can someone please tell me how to set the token in the request header when the superuser wants to download the file? Thanks. -
Can I manually feed the language code to Django gettext()?
I have a few strings in the backend I'd need to occasionally translate to other language before using them. I plan to save the user language selection into the database so it would be easy to get it from there. But, what is unclear for me, is if I implement localization and have a couple of different language files, how can I use the right language version? I can't read the language selection from cookies, url, user session etc. Can I use the language code from my database to choose which translation I'll use? -
Heroku / Django / MySQL : 2013 'Lost connection to MySQL server during query'
I've deployed a Django app to Heroku. The app works perfect in other environemnts, but in Heroku, one out of 5 request I got a Lost connection to MySQL server during query. I'm not hitting the app a lot, just testing it and it's unusable. I'm not sure where to start debugging this. I've added CONN_MAX_AGE = 60 to the django settings with the hope that keeping the connection alive would help, but no. -

I deployed the web app already to heroku and it works fine when CSRF protection is off, but when I add this protection I get the 403 error because: Origin checking failed - chrome-extension://theIDofMyExtension does not match any trusted origins.)

Can I add large numbers of filters programmatically

So I hoped that I could use a class decorator to define them as per this SO answer. No joy.

messages not appearing in admin on AWS dev server Django-3.1
context: Django 3.1 app deployed to a AWS lambda with terraform. I have not set up my production settings yet, this is my dev server. I'm using https://github.com/adamchainz/apig-wsgi I noticed that messages from django.contrib.messages don't appear when attempting to get the api key with djangorestframework-api-key via the admin. It being on the lambda means I'm unable to access the lambda REPL to create the api key programmatically. note: django-debug-toolbar also does not work and does so quietly, so I have a sneaking suspicion my context_processors settings are off so I don't have messages or DEBUG variables but I can't find the issue in my settings?? Below is my code without debug toolbar settings. project/settings/base.py DEBUG = True INSTALLED_APPS = [ 'app', 'rest_framework', 'rest_framework_api_key', 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', ] MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ os.path.join(BASE_DIR, 'templates'), ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] STATICFILES_FINDERS = [ 'django.contrib.staticfiles.finders.AppDirectoriesFinder', ] STATICFILES_STORAGE = 'storages.backends.s3boto3.S3StaticStorage' AWS_STORAGE_BUCKET_NAME= [redacted] AWS_DEFAULT_ACL = [redacted] AWS_QUERYSTRING_AUTH= [redacted] AWS_S3_REGION_NAME = [redacted] AWS_LOCATION = [redacted] USE_I18N = True STATIC_URL = '/static/' REST_FRAMEWORK = { ...
