What folder structure is required for a publishable Django app?
I have a Django app developed as part of my existing Django site that I'd like to separate out and publish on PyPI. What folder structure is required to make the app suitable for publishing to PyPI and importable via pip? Current folder structure (truncated): mysite/ - conf/ - mysite/ - __init__.py - settings.py - myapp/ - __init__.py - admin.py - models.py - manage.py -
Deploying django project with apache 2.4 doesn't work publicly
I am deploying a django project and I have configured the apache server with mod_wsgi as in many tutorials on the internet and the website was served successfully within the internal network using the server's IP and Port (80). After setting the ServerName, I still can access the website within the internal network using the IP but I can neither use the domain name I want internally nor publicly. I have made a special inbound rule in the firewall for my Port (80) to allow accessing the server. WSGIApplicationGroup %{GLOBAL} ServerName my.website.com:80 #ServerName localhost:80 <Directory /> AllowOverride none Require all granted </Directory> What else can I do to make my server publicly available using the domain? Thank you. -

Django-tables2: Change attribute for multiple columns in __init__()
I can't figure out how to change attribute for multiple columns in one for loop. I want to set orderable=False to multiple columns. The only way which works is to explicitely define all these columns so I can add orderable=False to constructor. class PizzaTable(tables.Table): class Meta: template_name = 'django_tables2/bootstrap-responsive.html' model = Pizza fields = ['created', 'ham', 'olives', 'corn', 'price',] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) unorderable_columns = ['ham', 'olives', 'corn',] for column in unorderable_columns: self.columns.get(column).orderable = False This raises: 'BoundColumns' object has no attribute 'get' It has to be able to do it somehow, otherwise I would have to specify all of those columns: ham = tables.Column(accessor='ham',orderable=False) Do you have any ideas? -
If Statement To Check if a Table is contained in an Iframe
Sorry if this question seems basic, but I cannot find any simple explanations and I'm new to JavaScript, so please give any help/feedback you can. Basically I have an HTML iframe called iframe, and I would like a JavaScript if-statement to see if any <table> objects are in it. I don't know exactly how to reference that in the if-statement. Any help would be much appreciated. -
Celery in dockerized django project
I have a django project consisting of blog, article and comment applications. Comment model has a generic relation to Article model from article app and Entry from blog app. I want the two models (Entry and Article) to show the number of comments.

django annotate related fields at once with Count()
My Profile model have two m2m fields in one model - region and country. And as you know, country has there own region with foreignkey. I want to try counting profiles per region - not only include region but also in country__region. i.e.) If some have only has Africa region, and other has only Congo country (with the region Africa), I want to filter them at one. I try to solve it using annotate. I can find count of region individually like below profiles = Profile.objects.all() region_count = profiles.values('region').annotate(region_count=Count('region')) country_count = profiles.values('region').annotate(region_count=Count('country__region')) But how can I count queryset with specific region, filtering with region and region__country at once? Is there any possible method? Here's my profile / country model. The region model just has name field. class Profile(models.Model): region = models.ManyToManyField( Region, verbose_name="Region(s) of interest", blank=True, ) country = models.ManyToManyField( Country, related_name="country", verbose_name="Countries of interest", blank=True, ) ... clsas Country(models.Model): region = models.ForeignKey( Region, null=True, blank=True, ) ...

Bootstrap navbar dropdown populated with database entries in Django 2
I am trying to populate a navbar "dropdown-menu" with individual "dropdown-item"'s populated from data in the sqlite3 DB. I have something similar working on other pages but I cant get it to work in my navbar. I am creating a record label, and want the list of artists populated from entries in the DB.

For example, when user's vacation is between 10 July and 20 July and in my report I set start date to 11 July it will return 0 days but it should calculate days between. This is because vacation_filter = models.Q(vacation__status=2, vacation__start__gte=self.start, vacation__end__lte=self.end) -- it uses vacation__start__gte - which … -
