Celery beat not sending task to worker in heroku, configured in a single dyno in free tier
I am making a website, where the user has to accept an agreement and then an expiration date is set for the user. On that date the contract is supposed to get expired by setting a contract_expired boolean field to True and sending an email to the respective user about the same. I used celery beat for this. Now since the site is in tessting phase, it is hosted in a free tier dyno in heroku, so I had to configure one dyno for web and the other for both celery worker and beat. I scheduled a task for beat where it would run daily on 9 am, to check the exipiries for the users and then do the work as mentioned above. This function was running correctly when I was testing it in the localhost, i.e., by running two seperate terminals for worker and beat. But today at 9 am it did not run in heroku. Below are the codes that i wrote for the entire process procfile release: python manage.py migrate web: gunicorn jgs.wsgi --log-file - celeryworker: celery -A jgs.celery worker & celery -A jgs beat -l INFO & wait -n celery.py from __future__ import absolute_import, unicode_literals import … -
How to use temporary file from form upload - Python Django
I have a form where users can upload up to 1,000 images at a time. I have changed my FILE_UPLOAD_MAX_MEMORY_SIZE in Django settings to 0 so all files uploaded via a form are written to a temp directory in my root folder. I am then trying to process the images with OpenCV. original_img = cv2.imread(temp_image.temporary_file_path()) gray = cv2.cvtColor(original_img,cv2.COLOR_BGR2GRAY) temp_image.temporary_file_path() This returns the absolute file path of the temp image in a string format So I put that in the cv2.imread, however, it creates a NoneType instead of a numpy array like it should and then my program cannot run when it reaches gray = cv2.cvtColor(original_img,cv2.COLOR_BGR2GRAY) How do I read the temporary file into OpenCV? Any help is much appreciated. -
Issue finding which comment to reply to using django-mptt for nested comments in a blog
I'm trying to create a nested comment system with djano-mptt. I have got it working and the comments are displaying as designed. However, when the issue I'm having is coming up with the logic for the user to choose which comment to reply to. Through the form I can display all the post and parent field and that allows the user to select a post and comment. Although the issue being they can comment on any post and any comment in the list. Trying to implement logic where if the user is on that post they can only comment on that post and can choose which comment (if they want) to reply to.

jQuery .addClass applying to everything
I have a like button that uses jQuery. The like button works as expected however due to the way I have it setup it changes every icon on the page to a heart code: if (data.liked) { updateText(this_, data.likescount, "") $(".like-btn").prepend("<i></i>"); $("i").addClass("fa fa-heart-o liked-heart"); //problem line } else { updateText(this_, data.likescount, "") $(".like-btn").prepend("<i></i>"); $("i").addClass("fa fa-heart-o unliked-heart"); //problem line From what i userstand the issue is that I am appending the class fa fa-heart-o ... to all i elements.

Logging in Django does not work when using uWSGI

Is there any other option for on_delete other than models.CASCADE for a ForeignKey in Django models>

How do I prepopulate Foreign key fields on django admin inline?
I have Service Groups and Services. Together, they create a unique relation GroupService which includes some other foreign keys.So, in django admin, upon creation of a group, I want to prepopulate service inlines with two default services' ids. I've tried overriding the BaseInlineFormSet for my inline but no success. Here's what I've tried, now it gives me KeyError: "Key 'id' not found in 'GroupServiceForm'. Choices are: counter, deduction, numerator, service.". When I tried to implement it using self.empty_form, I actually succeeded at displaying default services' foreing keys but could not save the form even if I had all my fields filled in. class CustomInlineFormSet(BaseInlineFormSet): def __init__(self, data=None, files=None, instance=None, save_as_new=False, prefix=None, queryset=None, **kwargs): super().__init__(data=data, files=files, instance=instance, save_as_new=save_as_new, prefix=prefix, queryset=queryset, **kwargs) default_services = Service.objects.filter( is_default=True).values_list('id', flat=True) services = [form['service'].initial for form in self.forms] for default_service in default_services: if default_service not in services: empty_form = self.form(initial={'id': 12, 'group': instance.id, 'service': default_service}) # empty_form.is_valid() self.forms.append(empty_form) class GroupServiceInline(CompactInline): model = GroupService fieldsets = ( (None, {'fields': ('service',)}), ('KPI', {'fields': ('counter', 'deduction', 'numerator')}), ) formset = CustomInlineFormSet extra = 2 -
Selenium: get file URL from WebElement (django, pytest)
I'm trying to test a django web app via Selenium and pytest. My test page has the following link displayed within a table (along with other links of the same format): <a href="/download_file/?file_path=serve/myid/results_XYZ.csv"><input type="button" value="Results (.csv)" /></a> I can get that webelement by using the following code: input_fields = self.driver.find_elements(By.CSS_SELECTOR, '\\input') for elem in input_fields: value = elem.get_attribute("value") if value == "Results (.csv)": csv_link = elem # more elif clauses to get the various links calling .click() on that webelement leads to a successful download of the file, so that works. Now, I also need to extract the actual download link from that element, to get the filename. What I have tried: print(mylink.get_attribute("href")) # prints None print(mylink.get_attribute('outerHTML')) # prints <input type="button" value="Results (.csv)"> print(mylink.get_attribute('innerHTML')) # prints nothing print(mylink.get_attribute("ownerElement")) # prints None The latter is surprising to me, because the following: mydic = mylink.get_property('attributes')[0] for key in mydic: print(f"\t{key}:\t{mydic[key]}") prints, among other things, ownerElement: <selenium.webdriver.remote.webelement.WebElement (session="c470b6e33d0b2fbec3f1a0e7e26dec55", element="81bdc092-0b8b-4069-a1ec-8a685fda18a5")> So I'm confused why I can't get that ownerElement. And also, why .get_attribute('innerHTML'), which I have seen advertized everywhere, does not give me anything. But mostly, I need to know: How do I get the file-url from such a download link? -
Google OAuth2 for Android using python-social-auth
I have a Django project, that implements Google OAuth2 with python-social-auth package. It works fine for Web applications. My config in settings.py: SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = os.getenv('GOOGLE_OAUTH2_KEY') SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = os.getenv('GOOGLE_OAUTH2_SECRET') AUTHENTICATION_BACKENDS = ( 'entity.oauth.backends.CustomGoogleOAuth2', 'entity.oauth.backends.CustomFacebookOAuth2', 'django.contrib.auth.backends.ModelBackend', ) SOCIAL_AUTH_STRATEGY = 'entity.oauth.strategies.CustomStrategy' After completing the request I generate JWT tokens for the user: def jwt_do_complete(backend, login, user=None, redirect_name='next', *args, **kwargs): ... if user: if user_is_active(user): # Get the JWT payload for the user. refresh = TokenObtainPairSerializer.get_token(user) payload = { 'refresh': str(refresh), 'access': str(refresh.access_token) } else: raise RuntimeError('Unauthorized', 'The user account is disabled.', status.HTTP_401_UNAUTHORIZED) else: raise RuntimeError('Unauthorized', 'The user account does not exist.', status.HTTP_401_UNAUTHORIZED) return user, payload So the workflow of the authorization is the following: Frontend authenticates by Google form and receives code and other information. It sends it to the complete route of the Django server. Django verify the code with help of python-social-auth. Django sends back JWT tokens. Here is the complete view: @never_cache @csrf_exempt @psa(f'{NAMESPACE}:complete') def complete_with_jwt(request, backend, *args, **kwargs): """Authentication complete view""" try: user, token_info = jwt_do_complete( request.backend, _do_login, user=request.user, redirect_name=REDIRECT_FIELD_NAME, request=request, *args, **kwargs ) except RuntimeError as e: if len(e.args) != 3: raise return HttpResponse(json.dumps({ 'status': e.args[0], 'message': e.args[1], }), status=e.args[2]) return HttpResponse(json.dumps(token_info)) It works fine as I said … -

NoReverseMatch for Django and DjangoCMS App

The links look like this <a href="{% url 'article-list-by-tag' %}{{ tag }}" class="badge badge-info" >{{ tag }}</a> The URL pattern article-list-by-tag comes from a DjangoCMS app called AldrynNewsblog.
