NoReverseMatch with keyword arguments not found when the keyword arguments match
I'm getting the error: Reverse for 'search_blog' with keyword arguments '{'search_terms': ''}' not found. 1 pattern(s) tried: ['blog/search/(?P[^/]+)/$'] So, my arguments match and yet I'm getting a NoReverseMatch... I've tried removing the <str:search_terms> pattern from the 'search_blog' path and excluded the kwargs parameter from my reverse call, and that worked. So, the problem must lie solely in the url pattern. I tried renaming the pattern to 'terms' but got the same error: Reverse for 'search_blog' with keyword arguments '{'terms': ''}' not found. 1 pattern(s) tried: ['blog/search/(?P[^/]+)/$'] Here are the relevant snippets: urls.py path('search/', views.nav_search_input, name='nav_search_input'), path('search/<str:search_terms>/', views.search_blog, name='search_blog'), views.py def nav_search_input(request): if request.method == 'POST': form = SearchBlog(request.POST) if form.is_valid(): return HttpResponseRedirect(reverse('search_blog', kwargs={'search_terms': form.cleaned_data['search_terms']})) else: form = SearchBlog() context = { 'form': form } return render(request, 'index.html', context) def search_blog(request, search_terms=''): posts = Post.objects.all() form = SearchBlog() if form.is_valid(): posts = Post.objects.all().filter(title__contains=search_terms) context = { 'form': form, 'posts': posts } return render(request, 'blog/search_blog.html', context) -
Django Selenium Chromedriver Saving Scraped Files to S3 Bucket
I created a scraping script with Selenium and Chromedriver. This is the header in sel.py. I used the example here: Downloading a file at a specified location through python and selenium using Chrome driver options = webdriver.ChromeOptions() prefs = {"profile.default_content_settings.popups": 0, "download.default_directory": DEFAULT_FILE_STORAGE, "directory_upgrade": True} options.add_experimental_option("prefs", prefs) driver = webdriver.Chrome(options=options) driver.get('https://unsplash.com/s/photos/download') I want to save the downloaded file into my S3 Bucket. I followed these tutorials: How to Setup Amazon S3 in a Django Project & Serve Django Static & Media files on AWS S3 | Part 2 Settings.py AWS_ACCESS_KEY_ID = 'xxxxxxxx' AWS_SECRET_ACCESS_KEY = 'xxxxxxxxx' AWS_STORAGE_BUCKET_NAME = 'xxxxxxx' AWS_S3_CUSTOM_DOMAIN = '%s.s3.amazonaws.com' % AWS_STORAGE_BUCKET_NAME AWS_S3_OBJECT_PARAMETERS = { 'CacheControl': 'max-age=86400', } AWS_LOCATION = 'static' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' STATIC_URL = 'https://%s/%s/' % (AWS_S3_CUSTOM_DOMAIN, AWS_LOCATION) DEFAULT_FILE_STORAGE = 'MyProject.storage_backends.MediaStorage' ADMIN_MEDIA_PREFIX = STATIC_URL + 'admin/' AWS_DEFAULT_ACL = None The "download.default_directory": DEFAULT_FILE_STORAGE in the sel.py is not working, because it keeps saving the photos in the downloads folder instead of S3. How can I make my S3 folder the download default directory? -
Does Django have the capability of sharing a field value between a pair of users such as a symmetric key?
I want a user to be able to take plaintext and paste it into a form to submit using a symmetric key and then receive the ciphertext. Then using the ciphertext another user who shares the symmetric key can use that key to decrypt that ciphertext. I'm new to Django and believe I need to setup a user model and use that model somehow to solve the problem but I'm not sure how and cannot find any information to help. I believe I need a special model because that's how you store and retrieve user information but I could be wrong. from django.contrib.auth.models import AbstractUser from django.db import models class CustomUser(AbstractUser): age = models.PositiveIntegerField(null=True, blank=True) key = models.?????? The actual results should be as follows: A user logs in and chooses from a list of users that they have "befriended" so to speak where they both share the same symmetric key(<--the topic of question). That user then takes plaintext such as a sentence or paragraph and pastes this information into an HTML form where they can click submit. Upon submission the plaintext is encrypted using the key respective of the intended recipient. Then that information runs through a encryption algorithm … -
Django/Apache Server Down but 403

Disable {% debug %} tag in Django template
Is there a way to prevent Django template from outputting a bunch of debug output? I tried setting DEBUG = False and setting my TEMPLATES option like so: TEMPLATES = [ { ... 'OPTIONS': { 'debug': False, 'context_processors': [ 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], } } ] Despite the above settings, whenever I put {% debug %} into my template, it still outputs a lot of debug information. -

Set up django-celery-email for local dev
It seems the best way to send emails from the django-allauth app asynchronously is to simply install django-celery-email. But the packages warns that This version requires the following versions:Python 2.7 and Python3.5, Django 1.11, 2.1, and 2.2 Celery 4.0 I've only been using python for several months and never encountered a situation where two python version are needed on a project. And I'm using the official recommendation of pipenv for local development. A quick google shows that it isn't possible to have two python interpreters installed in the virtual environment. Since the plugin seems so popular I wondered how others were setting it up? Apologies if I've missed something major that explains this. A bonus answer would also take into account that I am using docker and the docker image will install the python packages like this. RUN pipenv install --system --deploy --ignore-pipfile Many thanks in advance. -

DRF - How do I link back from model class with PrimaryKey to model class with ForeignKey
I have two models Job and JobDescription. I have a ForeignKey jobid defined in JobDescription. The django-rest-framework does its magic and finds the automatically created PK id in Job to link to. In serializers.py JobDescriptionSerializer jobid will give me a hyperlink to the Job id. So far so good. At this moment however, this is a one way street (JobDescription -> Job). I would like to add a field to Job model/serializer that will allow hyperlinking the other way around as well (Job -> JobDescription). I went through the Django models documentation around ForeignKey and there are some references to forward/backward relationships, but how do I implement this in the rest-framework models/serializers? Thanks for your help in advance! models.py: class Job(models.Model): title = models.CharField(max_length=100, default='') type = models.CharField(max_length=20, default='') location = models.CharField(max_length=100, default='') created_date = models.DateTimeField(auto_now_add=True) class Meta: ordering = ['id'] def __str__(self): return self.title class JobDescription(models.Model): jobid = models.ForeignKey(Job, related_name='desc2job', on_delete=models.CASCADE) description = models.TextField(blank=False) created_date = models.DateTimeField(default=timezone.now) class Meta: ordering = ['id'] def __str__(self): return str(self.jobid) serializers.py: class JobSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Job fields = ( 'url', 'id', 'title', 'type', 'location', 'created_date') class JobDescriptionSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = JobDescription fields = ('url', 'id', 'jobid', 'description', 'created_date') -
Django Testing - authenticate() returns None
Working on making some unittests with Django, and trying to make some testing with the login process with the login form. I am using modified User model just to make the email field unique; otherwise nothing drastically different. account/views.py def post(self, request): # Retrieve the username and password username = request.POST['username'] password = request.POST['password'] # Create a user object from authentication, or return None user = authenticate(username=username, password=password) # Check if user was created if user is not None: # Rest of the code, irrelevant... account/test_views.py def test_account_login_POST_successful_login(self): # Create a user to test login CustomUser.objects.create_user( username='test_user', email='test_user@intranet.com', password='flibble' ) response = self.client.post(self.login_url, { 'username': 'test_user', 'password': 'flibble' }) self.assertEqual(response.status_code, 301) account/models.py class User(AbstractUser): # Make the email field unique email = models.EmailField(unique=True) project/settings.py # Authentication AUTH_USER_MODEL = 'account.User' Funny thing is that login works normally on the web app, but when testing it always returns None. I've tried to check_password() with the created user, and it returns true in both the test method and the view method. I've also tried putting in AUTHENTICATION_BACKEND = ['django.contrib.auth.backends.ModelBackend'], but no go. -
Celery: different settings for task_acks_late per worker / add custom option to celery
This question is a follow up of Is there any way to find out the hash value of two files? I had a problem with celery (see the question that I follow up) and in order to resolve it I'd like to have two celery workers with -concurrence 1 each but with two different settings of task_acks_late. My current approach is not very beautiful. I am doing the following: in settings.py of my django project: CELERY_TASK_ACKS_LATE = os.environ.get("LACK", "False") == "True" This allows me to start the celery workers with following commands: LACK=True celery -A miniclry worker --concurrency=1 -n w2 -Q=fast,slow --prefetch-multiplier 1 celery -A miniclry worker --concurrency=1 -n w1 -Q=fast What would be more intuitive would be if I could do something like: celery -A miniclry worker --concurrency=1 -n w2 -Q=fast,slow --prefetch-multiplier 1 --late-ack=True celery -A miniclry worker --concurrency=1 -n w1 -Q=fast --late-ack=False I found Initializing Different Celery Workers with Different Values but don't understand how to embed this in my django / celery context. In which files would I have to add the code that's adding an argument to the parser and how could I use the custom param to modify task_acks_late of the celery settings. -
Django populating model in signal with accessing request
I am in trouble in populating a table, at first see my models. from django.contrib.auth.models import User class Group(models.Model): members = models.ManyToManyField( User, through='PersonGroup', related_name='person_of_the_group' ) class PersonGroup(models.Model): group = models.ForeignKey( Group, on_delete=models.CASCADE, related_name='group_person_of_group' ) person = models.OneToOneField( User, on_delete=models.CASCADE, related_name='group_person_of_group' ) I want when I create a group, the PersonGroup should populate automatically, I tried to achieve it in the signal but failed to do it, coz, I couldn't access request.user in signal @receiver(post_save, sender=Group) def create_person(sender, instance, created, **kwargs): if created: PersonGroup.objects.create( # ) Can anyone help to access to request in the signal? I need to solve this problem in signal at any means
