Scheduling a job with APScheduler: django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS [Django and Heroku]
I am trying to set a scheduled job in my Django app. I want this sheduled job to be run every x minutes while my app is on Heroku. I am following this article explaining how to scheduling jobs using custom clock on heroku (python). Inside my project main folder, I have my Procfile: web: gunicorn aqi_luftdaten.wsgi clock: python clock.py and my clock.py: from apscheduler.schedulers.blocking import BlockingSchedule # import the script I want to be run every x minutes # this fills a model with new data coming from an api from pm_lookup.processing.scheduled_processing import save_history_pm sched = BlockingScheduler() sched.add_job(save_history_pm, 'cron', id='run_every_1_min', minute='*/1') sched.start() I can see from my requirements.txt that I have installed APScheduler==3.6.3. In my heroku app settings I have installed the heroku/python buildpack Then I git add . git commit -m "implement scheduled job" git push heroku master And when it is successfully push I finally heroku ps:scale clock=1 But then I can see my model is not getting any new data.

Pagination not working with Django-Filter
I'm using Django-filters to filter results. The filter is working correctly, but now the pagination is not working. It's being rendered, but now all the products are being displayed in one page. I was using paginate_by = 6 as it is a class based view. Even after filtering results, for example there are 8 products matching the filter, everything is being displayed in one single page.

Conception: is my entity relation diagram correct?
I want to develop an app in Django to follow user account for our different applications. I have identify at least 3 entities: - Projects - Users - Applications A project can have many users. A user can be implied in many projects. A user in a project can have access to many applications. I think my first ER diagram is false (see below) because users will be duplicated for each projects it will be implied... I should have a many-to-many relationship between Projects and Users (intermediate models Project-User) and Applications should be related to this intermediate models Project-User with a FK. -
Django forms - nested filtering in a vew for form cleaned data validation
This is related to Filter queryset with multiple checks, including value_is_in array in a Django view, though addresses a slightly different issue. I need two levels of checking of my form data: I have a profile model with name, surname, and role (the last one is and array coming from a related model, one profile can have many roles). Upon submission of the form I need to check if a profile with a name and surname exists first; if it does, I need to check if that existing profile has already that role; if yes, throw an error. If not, keep the existing profile and only add the new role entered in the form. My models: class Role(models.Model): type= models.CharField(max_length=30) def __str__(self): return self.type class Profile(models.Model): first_name = models.CharField(max_length=120, null=True, blank=True) surname = models.CharField(max_length=120, null=True, blank=True) role = models.ManyToManyField(Role, blank=True) And this is what I have tried in my view: def clean(self): cleaned_data = super().clean() first_nameUnregistered = self.cleaned_data['first_nameUnregistered'] surnameUnregistered = self.cleaned_data['surnameUnregistered'] role = self.cleaned_data['role'] if Profile.objects.exclude(pk=self.instance.pk).filter( first_nameUnregistered=first_nameUnregistered, surnameUnregistered=surnameUnregistered ).exists(): if role__in=role: raise forms.ValidationError("This profile already exists") else: return cleaned_data return cleaned_data which gives me a syntax error on if role__in=role:.

using re.sub to find and replace all exact matches
The code below, aims to search hash signs in a string. If hash signed substrings ends in ([^\s#@$]*) it checks if the substring exists in database and if so it converts it to an anchor tag. if not bool(BeautifulSoup(content,"html.parser").find()): if "#" in content: title= re.findall(r"[#]([^\s#@$]*)(?=[\s#@$])", content) for i in title: if i not in check_list: check_list.append(i) try: title= Title.objects.get(title = i) c = re.sub("[#]({})([^\s#@$]*)".format(i,),"<a class='title-link' href='/titles/{}'>{}</a>".format(i,i),c) except: continue The problem occures when there is more then one hash signed substrings with the same value. Say the string is: "#title5 #title5xxx title5#title555" The result is: "<a class='title-link' href='/titles/title5'>title5</a> <a class='title-link' href='/titles/title5'>title5</a> title5<a class='title-link' href='/titles/title5'>title5</a>" But I want it to be: "<a class='title-link' href='/titles/title5'>title5</a> #title5xxx title5#title555" Because I want re.sub function to replace only exact matches starting with "#" and ending in [s-#-@-$] without replacing characters in which the string ends. As an amateur, I hope I expressed myself correctly without annoying you. Have a nice day! -
I want to be able to automatically mark a Boolean field as true after certain time frame, without using third party package
Am working on a django project, where users registered and pay if the payment have been verified i will update the paid attribute in the user Profile to True and automatically trigger a timer that calculate when the paid attribute will be return back to False after certain duration say 1 Day. How can this be done ? So far this is what i have achieved. class Profile(AbstractUser): paid = models.BooleanField(default=False) class TimeTracker(models.Model): user = models.OneToOneField(Profile,on_delete=models.CASCADE,related_name='usertime') created = models.DateTimeField(auto_now_add=True) @property def end_date(self): time_remaining = self.created + timedelta(days=1) time_remaining = time_remaining.strftime("%A %B %d %H:%M%p") since = str(time_remaining) return since I am able to Trigger the paid to True from the view function, when payment have been verified but i have not be able to set it back to false after 1 day. Something like if the difference between when the timer was created and now is 1 day, set the paid attribute to False. E.g if current_datetime - created == 1day: Profile.paid = False profile.save() I don't want this to be done by the user meaning,i want that function check to be running on his own and whenever i return true it update the user paid in its Profile to False. … -

Django channels group handler / group manager
I'm willing to use Django-channels for creating a game backend, for the question purpose let's say it's a [multiplayer] trivia game. A client connect to the server and a Consumers handle its socket. Then, the client send a message that connect him to a specific group (group will be 1 instance of a game) after there are some users in a group, the game should start.. My question is: is there any way to create a "group handler"/"group manager" that run on the server and also connect to the same channel group and manages the gameplay? like send the questions to all other players, says who wins, etc.. I saw there is some "worker" in the channel library but it's not seems to be the solution becuase it's not dynamic, you need to run the worker manually.. Thanks! -

Channels consumers garbage collector
What happens to a consumer instance after a websocket client disconnects? Is there any specific cleanup of the instance done, or just regular garbage collection? Is it possible to reconnect to a channels consumer instance to recover the state of that instance? -
Upload multiple files in Django admin
Django==3.0.6 models.py class Image(models.Model): image_42_webp_1 = models.ImageField(upload_to=_get_upload_to, validators=[validate_image,], blank=True, verbose_name="42 webp 1х") image_42_fallback_1 = models.ImageField(upload_to=_get_upload_to, validators=[validate_image,], blank=True, verbose_name="42 1х") image_42_webp_2 = models.ImageField(upload_to=_get_upload_to, validators=[validate_image,], blank=True, verbose_name="42 webp 2х") <...> There are much more image fields in the model. As a matter of fact more than 50. Why do I need them is another question. But in short every image is adjusted manually for better site performance. Anyway, there are a lot of image fields and I wouldn't like to overburden the admin by loading so many files one at a time. I'd like to use something for bulk upload. I have failed to find a ready made app. So, if you suggest me some app, that would be great. If not, well, any solution would suit. Maybe this can be somehow used? https://docs.djangoproject.com/en/3.0/topics/http/file-uploads/#uploading-multiple-files In model admin the template 'includes/fieldset.html' is responsible for creating/editing new model instance. What I need is just some means not fill the fields by hand. Any means, even Selenium would suit. Or maybe a raw http post request (though login is required and CSRF protection is switched on). Could you help mehere? -
Generating Custom html ids using Django for Bootstrap Carousels
I am generating a carousel for each gallery in my django model. However, as you know each Carousel in Bootstrap 4 requires their own id in order to use carousel-controls. To overcome this I tried to use the id of my model. However, instead of going back and forth between my images. The carousel buttons lead to a link with the id of the gallery selected. I've attached the code for my Carousel down below. {% for pics in gallery %} <div class="d-flex flex-column py-3 px-3 text-center"> <h4 class="">March 25th 2020</h4> <h1 class="mt-n2">{{pics.title}}</h1> <h6 class=""><a>View Full Gallery</a></h6> </div> <div class="container-fluid pb-4"> <div id="{{pics.id}}" class="carousel slide carousel-fade" data-ride="carousel"> <div class="carousel-inner"> <ul class="carousel-indicators"> {% for picture in pics.images.all %} {% if forloop.counter == 1 %} <li data-target="#{{pics.id}}" data-slide-to="{{forloop.counter0}}" class="active"></li> {% else %} <li data-target="#{{pics.id}}" data-slide-to="{{forloop.counter0}}"></li> {% endif %} {% endfor %} </ul> {% for picture in pics.images.all %} {% if forloop.counter == 1 %} <div class="carousel-item active"> {% else %} <div class="carousel-item"> {% endif %} <img src="{% thumbnail picture.image 1200x600 crop detail %}" alt="Image" class="d-block w-100"> <div class="carousel-caption"> <h3 class="h3-responsive">XXXXX</h3> <p> {{picture.description}}</p> </div> </div> {% endfor %} </div> <a class="carousel-control-prev" href="#{{pics.id}}" role="button" data-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="sr-only">Previous</span> </a> <a class="carousel-control-next" href="#{{pics.id}}" …
