Celery Tasks are executing multiple times in Django Application
I have a Django application where I defined a few @task functions under task.py to execute at given periodic task. I'm 100% sure that the issue is not caused by task.py or any code related but due to some configuration may be in settings.py or my celery worker. Task does execute at periodic task but at multiple times. Here are the celery worker logs: celery -A cimexmonitor worker --loglevel=info -B -c 4 [2019-09-19 21:22:16,360: INFO/ForkPoolWorker-5] Project Monitor Started : APPProject1 [2019-09-19 21:22:16,361: INFO/ForkPoolWorker-4] Project Monitor Started : APPProject1 [2019-09-19 21:25:22,108: INFO/ForkPoolWorker-4] Project Monitor DONE : APPProject1 [2019-09-19 21:25:45,255: INFO/ForkPoolWorker-5] Project Monitor DONE : APPProject1 [2019-09-20 00:22:16,395: INFO/ForkPoolWorker-4] Project Monitor Started : APPProject2 [2019-09-20 00:22:16,398: INFO/ForkPoolWorker-5] Project Monitor Started : APPProject2 [2019-09-20 01:22:11,554: INFO/ForkPoolWorker-5] Project Monitor DONE : APPProject2 [2019-09-20 01:22:12,047: INFO/ForkPoolWorker-4] Project Monitor DONE : APPProject2 If you check above time interval, tasks.py executes one task but 2 workers of celery takes the task & executes the same task at the same interval.

Catching bulk events in Django
I have Book model. It has some fields like title, year publish and etc. Also, i have overrided save() method. When new books is adding, it checks if book exsists, it creating new directory with name self.title in MEDIA_ROOT path. def save(self, *args, **kwargs): book_dir = os.path.join(MEDIA_ROOT, self.title) # check that at least one file is loading if all([self.pdf, self.fb2, self.epub]): raise ValidationError("At least 1 file should be uploaded!") # create book's directory if it not exists if os.path.exists(book_dir): raise ValidationError("This book is already exists!") else: os.mkdir(book_dir) # rename and edit storage location of books to book_dir for field in [self.image, self.pdf, self.fb2, self.epub]: field.storage.location = book_dir super().save(*args, **kwargs) # Call the "real" save() method. Also i have overrided delete() method, that just remove directory of deleted book. def delete(self, *args, **kwargs): book_dir = os.path.join(MEDIA_ROOT, self.title) rmtree(book_dir) super().delete(*args, **kwargs) # Call the "real" delete() method. delete() method works well if i delete only 1 book. But, if i want to delete multiple files (all actions take place in the admin panel), only DB records got deleted. So, i want to just catch this moment to remove directory of deleted book. -
m2m_changed when items added and removed
I'm wondering if it's possible to gather the 'end state' of a m2m field in Django? I'm currently using m2m_changed.connect(myfunction, sender=MyModel.tests.through) And I have: myfunction(**kwargs): action = kwargs.pop('action', None) instance = kwargs.pop('instance', None) if action in ["post_remove", "post_add"]: instance.owned_tests = instance.tests.count() instance.save() My problem is that if I add and remove items from the m2m field and then save, two m2m_changed signals are fired, one for the add, and one for the remove. Is there any way to group these together in order to only have myfunction called once when all changes to the m2m field are finished? -

How to implement a button of the searchbar erasing the query? Django environment)
I am developing a webapp in Django. I developed a nice search bar with two buttons. One of these (fa fa-search) is to search and display the results of the database, and it is altrady working.

Django fieldset.html override
So I decided to override all the Django templates for a custom look and feel for my WebApp. One problem I'm coming across though, is that I want to change the classes of these fields to form-control (I'm using bootstrap). I see that there's a built in function is_checkbox but there isn't anything to see if it is an input tag or a select tag. What I basically want to do is for Django to iterate over all the fields in the field set if a field is an input tag, I want to add the form-control class to it and if it is a select tag, I want to add the selectpicker class to it. Here's the Django code I'm referencing: <fieldset class="module aligned {{ fieldset.classes }}"> {% if fieldset.name %}<h2>{{ fieldset.name }}</h2>{% endif %} {% if fieldset.description %} <div class="description">{{ fieldset.description|safe }}</div> {% endif %} {% for line in fieldset %} <div class="form-row{% if line.fields|length_is:'1' and line.errors %} errors{% endif %}{% if not line.has_visible_field %} hidden{% endif %}{% for field in line %}{% if field.field.name %} field-{{ field.field.name }}{% endif %}{% endfor %}"> {% if line.fields|length_is:'1' %}{{ line.errors }}{% endif %} {% for field in line %} <div{% … -

I have looked at several examples on how to build a modal from scratch but I'm stuck at getting the display property to change using my JavaScript code. <script type="text/javascript"> var span = document.getElementsByClassName("ex"); var modal = document.getElementsByClassName("vid-modal") function clearModal() { modal.style.display == "none"; } function windowOnClick(event) { if (event.target === span) { clearModal(); } } function fireWhenReady(func) { document.addEventListener('DOMContentLoaded', func) } fireWhenReady(windowOnClick); </script> .vid-modal { position: fixed; background-color: rgba(0, 0, 0, 0.4); width: 1000px; height: 500px; top: 250px; left: 50%; margin: 0 auto; z-index: 1002; transform: translateX(-50%); /* display: initial; */ /* aug 21 still working on modal display */ display: initial; } <div class="vid-modal"> <span class="vexit"><i class="fa fa-window-close ex" aria-hidden="true"></i></span> <div class="vid-box"> <iframe id="front-video" src="https://www.youtube-nocookie.com/embed/Hua4MRTKmy0?rel=0&amp;controls=0&amp;showinfo=0;autoplay=1" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe> </div> </div> I expect to set the display property to "none", and apply more advance solutions to this code. -
How to call the correct view method in Django?
I have a project with these files and folders: ... old project new common manage.py ... I access the "old" using http://127.0.0.1:8000/old and there are views, form urls, etc files inside this folder. all works fine. I have similar files inside "new" folder as well. It also runs well: http://127.0.0.1:8000/old However I run into problems when I have a method inside view ("method1") and I declare it inside urls. However it searches for the method1 inside folder "old" not in "new". $.post('{% url "method1" %} inside urls I have path('method/', views.method1, name='method1'), I have no idea why this js searches for method1 inside "old". When I declare method1 inside old folder, it works fine. What am I missing here? -
django all-auth authenticating via twitch
I am trying to authenticate a user from twitch Auth using Django and reactjs. I am able to authorize the user and store its details in the Django admin from backend but not sure how to do it from reactjs. What I tried so far: Following the documents from here: https://django-allauth.readthedocs.io/en/latest/installation.html I configured everything as: settings.py: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'rest_framework.authtoken', 'rest_auth', 'django.contrib.sites', 'allauth', 'allauth.account', 'allauth.socialaccount', 'allauth.socialaccount.providers.twitch', 'django_extensions', 'users.apps.UsersConfig', ] SITE_ID = 1 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', ] ROOT_URLCONF = app-name.urls' TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [], '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', ], }, }, ] WSGI_APPLICATION = 'sphinx.wsgi.application' REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication', ], } I also registered the social application in the Django admin. When I hit: http://localhost:8000/accounts/twitch/login/ It takes me to the twitch authorization page, Which when I click on "Authorize" saves the user details in the Django admin redirects me back to the url: http://localhost:8000/accounts/profile/ The problem is I need to make sure the LOGIN_REDIRECT_URL page '/accounts/profile/' has some authentication so only the logged in user can access it and to display the username of that …
