Django 1.11 is not loading css files
I have the next configuration: urls.py urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^manager/', include('manager.urls')), #Static pages url(r'^index', TemplateView.as_view(template_name='index.html'), name='index'), url(r'^', TemplateView.as_view(template_name='index.html'), name='index'), url(r'^contact', TemplateView.as_view(template_name='contact.html'), name='contact'), url(r'^services', TemplateView.as_view(template_name='services.html'), name='services'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) settings.py import os BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'django.contrib.sites', 'pf.app.pfs', ] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [ os.path.join(BASE_DIR, "assets"), #'/var/www/static/', ] I executed the command: python manage.py collectstatic And the files are generated, also I added a css file with a single rule but and executed the command again.

django channels send many in single function
I am new in django channels. It is a image uploads app. Since it takes a long time. I am trying to print log onto front end. My code is like: def upload(m): m.reply_channel.send({ 'accept': True, }) socket_handler = SocketHandler(m) inst = ImageUpload(socket_handler=socket_handler) inst.newPic(m) m.reply_channel.send({ 'close': True, }) return And SocketHandler is like: class SocketHandler(logging.Handler): def __init__(self, message, *args, **kwargs): super().__init__(*args, **kwargs) self.message = message def emit(self, content, *args, **kwargs): self.message.reply_channel.send({ 'text': '['+datetime.datetime.now().strftime('%Y-%m-%d %H-%M-%S')+'] '+content.name+' '+content.msg, }) But not like my expectation, the logging only shows up on front end after the upload function returned. I would like to list the logs one by one. So what can I do? -

Progress bar for back end python programs on Django or other web frameworks
I've been searching and iterating a lot recently trying to figure out how to have a real time progress bar on the webpage to show the progress of programs running at the backend at the server. Right now I'm using Django for building the website as I need to run python programs on the server. So far when the web user click "submit" button, it will take the python program (written in views.py) about one minute to present the result and having a progress bar can really help here. Hope I provided enough detail about my question and thank you in advance for any one who can help. -

How to track the time Django takes to run migrations?
I have multiple Django apps with loads of migrations, and they can take a long time to run when building on a VM. For logistic reasons, and to identify areas where we can increase speed I'd like to be able to view the time it took for all migrations to run. What would be the preferred way of doing so? Maybe a management command that kicks off when you run migrate? Can't seem to find much on the topic. -

Block malicious user creation with Django?
I have an issue with a user who is creating many malicious accounts with the intent of spamming our service. I'd like to block this user from creating additional accounts. My first thought is to store users' IPs, identify the IP this user is posting from, and then require all users posting from the user's IP to go through additional verification (some kind of real ID, tax ID, phone number, etc. -- something that isn't as easily duplicated as an email address) (along the lines of this question How can I track IPs to block malicious users?). Are there other ways that are recommended for preventing the creation of malicious accounts, more generally? Is there a specific Django best practice to avoid this problem? I am thinking that I will save the IP in an associated Profile model, but wanted to make sure that there wasn't another, accepted way of preventing this issue, since it must be a fairly common problem. -
Django url disspatcher matches the wrong regex

Django Material navbar issue
We're using Django Material (MaterializeCSS as CSS framework) on a new project we are building, and we got an issue with a language selector in the admin navbar. The issue is happening on Firefox, not on Chrome, and I couldn't find what's causing this. Can you check it please? The URL is: https://accountant.swapps.io. Here is how it looks for reference. The templates doesn't have a lot, and the CSS for this is minimal but I can provide code if needed. Thanks! -

Get next work-item in Django with PostgreSQL
Imagine you have a simple table with work-items: |ID |OWNER|... +---+-----+--- |123| |... |456| |... |789| |... We want to provide a http API to get the next work-item which does not have an owner yet. We use PostgreSQL. We access the table with Django-ORM. I guess there are several race-conditions if the API gets access simultaneously by many users. How can I ensure with the given tools (PostgreSQL, Django) that all race conditions are solved (it is a major fault if a work-item is given to two ore more users). -

Basically, how can I select the attributes which are shown for each object on that page? -

How to implement FirebaseDB with a Django Web Application
Am trying to implement Firebase Realtime Database with my Django Web Application. After properly setting up the configuration with Firebase, I got confused about how data will write into my Firebase Database from my Django website instead of using Sqlite, or Postgres.

Form overriding: is it the good "Python-way" of doing this?
Form and ModelForm are two different things, but they both inherit BaseForm. I need to have both my own custom ModelForm and my own custom Form that share the same constructor.

Django let me log in in Firefox but not in chrome
I recently started playing with Django. When I try to log in into the admin panel, it succeeds in Firefox but doesn't in Google Chrome.
