python coverage - specify the working directory
I have a django application called edison with multiple django-apps in it. I run tests on them using coverage: coverage run --source='.' edison/manage.py test application_one coverage run --source='.' edison/manage.py test application_two ... My repo structure is: -- edison [the repo name] -- edison [a django application] -- schuedled_jobs -- internal_packages In my tests files I import stuff from internal_packages directory and when I run the coverage commands i get the error ModuleNotFoundError: No module named 'internal_packages'. My question is: how do I change the working directory of coverage to be the root directory - so it will recognise all modules? -
Django static files to AWS S3 return 403 forbidden
I'm working on a Django(3) project which is deployed at Heroku. I'm trying to connect AWS S3 using Django Storages to upload Static and Media files to S3 Bucket. Note: I have googled a lot and tried every solution I found, but nothing solved my issue, so don't mark this as duplicate, please! I have created an S3 bucket with the Public access enabled and added the following CORS configuration: [ { "AllowedHeaders": [ "*" ], "AllowedMethods": [ "GET", "PUT", "POST" ], "AllowedOrigins": [ "*" ], "ExposeHeaders": [] } ] Also, created an IAM user with programmatic access and gives the permission as S3FullAccess And here's what I have in **settings.py** AWS_ACCESS_KEY_ID = os.environ.get('AWS_ACCESS_KEY_ID') AWS_SECRET_ACCESS_KEY = os.environ.get('AWS_SECRET_ACCESS_KEY') AWS_STORAGE_BUCKET_NAME = os.environ.get('AWS_STORAGE_BUCKET_NAME') AWS_QUERYSTRING_AUTH = False AWS_S3_FILE_OVERWRITE = False AWS_DEFAULT_ACL = None AWS_S3_REGION_NAME = 'us-east-1' DEFAULT_FILE_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3StaticStorage' If I open files from the bucket directly I can see the file in the browser, but when I load my site (pythonist.org) these files return with 403 forbidden Here's the response from browser's Network tab for a file: Summary URL: https://s3.amazonaws.com/pythonist.org/css/normalize.css Status: 403 Forbidden Source: Network Initiator: pythonist.org:18 Don't know what's wrong here, Thanks in advance! -

How to get current user in models.py?
I have a model like this class Orders(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) The logic is the companies to send offers to get the specific travel. When you send an offer you will not have access to that travel anymore untill the base company accept or reject your offer. So when the specific company logged in I want to show them if they sent an offer or not. The company name is saved in the user that is logged in. What I tried to do is this class Order(models.Model): @property def has_sent_offer(self): Offer.objects.filter(order=self.pk, company=request.user.company) But in the models.py I don't have access to request.user -

django CSRF_TRUSTED_ORIGINS not working as expected

Im receiving a 403 error after the post stating the the csrf check has failed. I thought that adding the site to CSRF_TRUSTED_ORIGINS should make the site exempt from csrf checks.

Why this search doesn't work for another entry but CSS?
So I'm currently working for Harvard CS50 Project1:Wiki and I have a difficulty for this project.

How To Create An Article Parser Loop With Apscheduler in Django
I have a script in Django that helps me parse RSS feeds for my own daily consumption. It gets the jobs done so far. Its made 3 models: class Categories(models.Model): category_name = models.CharField(max_length=50, verbose_name='Categories') ''' Categories = ['Business', Sports, Politics, Tech] ''' class FeedSource(models.Model): feed_url = models.URLField(verbose_name='RSS Feed Link') ''' FeedSource = ['http://rss.cnn.com/rss/edition.rss', ''https://www.espn.com/espn/rss/news, 'http://rss.politico.com/politics.xml'] ''' class Posts(models.Model): ... source = models.ForeignKey(FeedSource, on_delete=models.CASCADE, verbose_name='Source') category = models.ForeignKey(Categories, on_delete=models.CASCADE, verbose_name='Category') The Apscheduler command is as follows. As you can see, there is a bit of repetition in the fetch_articles functions that parse different links because each link belongs to a different Feedsource & Category. The same applies to Handle function. Each fetch_articles function has its own scheduler. import logging from django.conf import settings from django.core.management.base import BaseCommand from apscheduler.schedulers.blocking import BlockingScheduler from django_apscheduler.jobstores import DjangoJobStore from Posts.models import Posts, FeedSource, Categories import time logger = logging.getLogger(__name__) def save_new_articles(feed, source_id, category_id): """Function that parses & saves new articles to DB""" ... if not Posts.objects.filter(guid=item.guid).exists(): post = Posts( ... guid = item.guid, source_id = selected_source_id category_id = selected_category_id ... ) post.save() def fetch_siteA_articles(): """Fetches news artices from siteA""" feed = feedparser.parse("siteA") source = FeedSource.objects.get(pk=1) source_id = int(source.pk) category = Categories.objects.get(pk=3) category_id = int(source.pk) … -

How to use variable to get attributes of another another variable in Django templates
I am trying to populate a CSS grid in a Django template with specified columns and rows. To my best understanding, I need to do something like “nested variables” in the Django template to achieve what I’m looking for. I tried this, but it does not work: {% for parent_row in parent_rows %} {{ parent_row }} <div>p1</div> <div>p2</div> {% for child_row in children_rows %} <div> {{ child_row}} </div> {% for guy in guys %} <input type=”text” value=”{{guy}}.{{child_row}}”></input> {% endfor %} {% endfor %} {% endfor %} The {{guy}}.{{child_row}} neither some of the similar variants I tried do not work. I manage to get the result I'm looking for by just writing the whole HTML open, and then by looping through each guy on separate rows, as I can use for example guy.name to get the desired value to each row, but this means lots of repetition. parent_rows could look something like this for example: “names”, “contact_information”, “hobbies” children_rows could look something like this for example: “forename”, “family_name”, “phone_number”, “mail”, “favourite_hobby” and two records in the guys would be like this (both identical, to ease illustration): “forename”: “Mike” “family_name”: “McMediocre” “phone_number”: “123” “mail”: “mike@mediocre.com” “favourite_hobby”: “tennis” I am trying to populate … -
Django custom model manager for derived class - filtering on base class attribute

I get the error message: 'ApprovedPublishedArticlesManager' object has no attribute 'approved_objects' Which makes sense, since ApprovedPublishedArticlesManager does not derive from Authorisable. How do I create a custom manager that allows me to filter based on base class properties - does my custom manager have to derive from models.Manager and the relevant base class (Authorisable in this case)? -

(See code below) But now I'm getting the following error. django.template.exceptions.TemplateDoesNotExist: activate_email.html Even though the template exists: views.py # import file with html content html_version = 'activate_email.html' # 'templates/activate_email.html' also doesn't work html_message = render_to_string(html_version, {'context': context, }) email = EmailMessage( 'MySubject', html_message, 'info@example.co', [user.email], ) email.send() settings.py TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'django_backend/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', ], }, }, ] Can anyone point me in the right direction what I'm doing wrong? I'm using Django 4.0 and DRF 3.13.1 -
Bootstrap 5 get rid of big number input fields
I have a table that can be used as a form, which all quite works well, but I do not manage to reduce the space a number input takes: here is a view from when it is not a form: What argument can I put in th class or td so the green areas get minimized? Fixed width in pixels would be an option (is this possible?). I already tried <th class="w-25"> or <td class="w-25"> (and both). I achieved adding a class="w-50" argument to the number input fields, so this seems to work. <table class="table table-striped table-hover"> <thead class="thead-dark"> <tr> {% for col in header %} {% if col == "number" %} <th>{{ col }}</th> {% else %} <th>{{ col }}</th> {% endif %} {% endfor %} <th class="text-end">action</th> </tr> </thead> <tbody id="table"> <tr> {% for key, value in product.data.items %} <td>{{ value }}</td> {% endfor %} </tr> </tbody> </table>
