Is there a quick way to grab a the ending of current page url? Django
I have a page. www.example.com/chat/testuser I want to grab the username (testuser). I'm doing this within the template in order to pass along in an ajax call. Is there a simple way? Something like {{ request.path }} (this returns full path). -

Two annotations in a single query
I am trying to build a query set to do a count, the query set involves three models. class Owner(models.Model): name = models.Charfield(max_length=10, null=false) class Location(modes.Model): name = models.Charfield(max_length=10, null=false) tenant = models.ForeignKey(Owner, on_delete=models.SET_NULL, null=True, blank=True) class Asset(models.Model): name = models.Charfield(max_length=10, null=false) tenant = models.ForeignKey(Tenant, on_delete=models.SET_NULL, null=True, blank=True) Location = models.ForeignKey(Owner, on_delete=models.SET_NULL, null=True, blank=True) I am trying to do a count for Locations for the owner and Assets for the owner, I can achieve this as two separate Querysets as follows: locations = Owner.objects.all().annotate(locations=Count('location')) assets = Owner.objects.all().annotate(assets=Count('asset')) This works fine, but what I'm trying to do is get a single row for both values and build a table similar to the one below. | Owner | Assets | Locations | |--------+--------+-----------| | owner1 | 10 | 3 | | owner2 | 100 | 20 | | owner3 | 70 | 50 | I've tried to put both annotations in a single query but I don't appear to get the right results, the count is either the same for both assets and location or I get very large numbers which I assume because both count operations are impacting each other. Query below gives me the same numbers for both asset and … -

keep getting error when trying to run makemigrations locally with Django/Postgres/Heroku site
I need to be able to add models to my site and I was unable to migrate new models to heroku. I've read that the only way peope are able to do it is to run the migrations locally.

Django AJAX Request Only Getting Last Element (not getlist issue)
I'm trying to make a tagging system in Django. Basically I'm passing through a list of tags (checkboxes in a form) through AJAX to a Django view which will update the list of tags with a new selection of relevant tags in an httpresponse. The problem is that Django only seems to be receiving the last element of the list on its own even after getlist. In fact, if I print the entire request.GET, it shows just one element in each list. The javascript/jQuery code is here: $(document).on('change', '.form-check-input',function () { var all_tags = $("input:checkbox").map(function() { return this.id; }).get(); var selected_tags = $("input:checkbox:checked").map(function() { return this.id; }).get(); alert(all_tags); alert(selected_tags); $.ajax({ url: "{% url 'AJAX_tagFilter' %}", data: { 'all_tags': all_tags, 'selected_tags': selected_tags }, cache: false, type: 'GET', success: function (data) { alert(selected_tags); $('#test').html(data); console.log('success'); } }); }); And I did a couple of alerts so that I can see what is being passed is correct at each stage. I see all the tags I expect it to. 12,13,21,16,17,15,11,7,18 12,13 But when it gets to the Django view: def getTagFilterSidebar(request): if 'selected_tags[]' in request.GET: all_tags = request.GET.getlist("all_tags[]") selected_tags = request.GET.getlist("selected_tags[]") debug_text4 = str(request.GET) I don't see the list of tags. This is … -
Overriding get_context_data is blocking some context data going to the template

django model for view with multiple joins
I have a question about making a Django model for a Postgres View. My view is created in my database, and it uses joins on multiple tables. This is my view: select cp.trade_date, ins.symbol, mgr.username, pt.strategy, pt.substrategy, pos.quantity, cp.price from position pos join manager mgr on pos.manager_id = mgr.id join instrument ins on pos.instrument_id = ins.id join price cp on cp.instrument_id = ins.id and cp.trade_date = pos.trade_date join portfolio pt on pt.manager_id = mgr.id and pos.portfolio_id = pt.id Among other fields, I believe the trade_date and manager_id fields are the most confusing to me in terms of setting up the model. The field trade_date lives on the following two tables, position and price. Similarly, the manager_id field lives on the following three tables, manager, position, and portfolio. All of the tables are properly using foreign keys as described in the JOIN statements above, and I can share their Django models if desired (my models share a name with the database tables). This is how I picture the View's model (to get the trade_date field) being completed but ManyToManyField doesn't have a 'to_field' option. Both tables position and price have many records with the same trade_date. I have read about the … -

How to display datetime field with a certain format
I have a datetime field column where I use in my detail view template. I show this in my HTML page as: {{ post.created_at }} and the output is: July 15, 2018, 7:03 p.m Which is way verbose than I need it to be. I would like the following: If I posted a post 59 minutes ago, it should display as 59m If I posted a post 23 hours ago, it should display as 23h If I posted a post 6 days ago, it should display as 6d Now anything that exceeds a week's time, should be displayed as day, month, year. In the example we have above it should be: 15 Jul 18 with no time. Is there a way to accomplish this in the HTML page using Jinja? -

Custom method for unlimited *args with set() function usage?

So, as you can see we have same usage with set() function. And I need to change this usage with custom method. I tried to write a method like this; def _get_deleted_lists(self, *args): value = set() for arg in args: value |= set(arg) return value and usage will be change like; lists_to_delete = self._get_deleted_lists(list_x, list_y, ...) instead of this; lists_to_delete = set(list_x) - set(list_y) But my custom method not return same value as before. How can I achieve this? -

However when trying to log in by tenant1.domain.com/admin getting login screen but after entering credentials getting ProgrammingError at /admin/login/ relation "auth_user" does not exist Looks like it is not picking up my tenant1 schema? What I have to change in configuration? -
How do I read this line given to me by django debugger? (NoReverseMatch)
There are several posts on here already about NoReverseMatch, I've read the documentation and understand why I am receiving this error (what raised it) but I'm struggling to find out how to fix it. I was originally going to post hoping someone could tell me what I'm doing wrong so I could fix it. I figured that wouldn't help me much so I instead was wondering if someone could tell me how to read this line: Reverse for 'detail' with arguments '('', 2, 1)' not found. 1 pattern(s) tried: ['projects\\/categories\\/(?P<category_slug>[-a-zA-Z0-9_]+)\\,\\ (?P<category_id>[0-9]+)\\/(?P<project_id>[0-9]+)$'] Specifically: ['projects\\/categories\\/(?P<category_slug>[-a-zA-Z0-9_]+)\\,\\ (?P<category_id>[0-9]+)\\/(?P<project_id>[0-9]+)$'] Obviously, this is a common type of syntax used by Django (and I believe programming in general) so I'd rather be taught to understand this so I can then better debug these situations myself. Thanks! Relevant Code index.html {% block content %} <h1>Recent Projects</h1> {% for project in recent_projects %} <li><a href="{% url 'projects:detail' project.category.slug project.category.id project.id %}">{{ project.name }}</a></li> {% endfor %} {% endblock %} urls.py app_name = 'projects' urlpatterns = [ path('', views.index, name='index'), path('categories/', views.categories, name='categories'), path('categories/<slug:slug>, <int:category_id>/', views.category_detail, name='category_detail'), path('categories/<slug:category_slug>, <int:category_id>/<int:project_id>', views.detail, name='detail') ] The relevant view: def detail(request, project_id): project = get_object_or_404(Project, pk=project_id) return render(request, 'projects/detail.html', {'project': project}) -

Upload image using Django built in forms
I am trying to upload an image using the Django built in forms, and can't seem to get the image to actually be stored. The form functions as expected, where I can browse for a file, and submit the form (everything else from form is posted and saved), but the image does not get saved into the "media/images" folder What am I missing here? models.py from django.db import models from django.conf import settings from django.contrib.auth.models import AbstractUser from django.db.models.signals import post_save from django.db.models.signals import pre_save from django.core.files.storage import FileSystemStorage class CustomUser(AbstractUser): customerTag = models.CharField(max_length=50,) deviceSerial= models.CharField(max_length=50,) image = models.ImageField(upload_to='images/', blank = True) forms.py from django import forms from django.contrib.auth.forms import UserCreationForm, UserChangeForm from .models import CustomUser class addNewEquipmentForm(UserCreationForm): class Meta(UserCreationForm.Meta): model = CustomUser fields = ('username', 'email', 'customerTag', 'deviceSerial','image', ) urls.py from django.urls import path, include from . import views from django.conf.urls.static import static from django.conf import settings urlpatterns = [ #path('', views.home), path('login/', include('django.contrib.auth.urls')),#django powered login page path('newequipment/',views.addEquipment.as_view(), name='newEquipment'), ] + static(settings.MEDIA_URL, document_root = settings.MEDIA_ROOT) settings.py STATIC_URL = '/static/' MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, 'media') STATICFILES_DIRS = [ os.path.join(BASE_DIR, "static") ] STATIC_ROOT = os.path.join(BASE_DIR, "static_files") -
django rest framework api to make a connected API of various views.
I have a Django view which goes like this. def active_part_redirect(request): user = request.user if user.is_authenticated: student_state_ = CurrentActiveState.objects.filter(user= user) if student_state_.exists(): student_state = student_state_.first() if student_state.active_part == 1: return redirect('content:show-content') elif student_state.active_part == 2: return redirect('content:illustrations') elif student_state.active_part == 3: return redirect('content:questions') elif student_state.active_part ==4: return redirect('content:report') elif student_state.active_part ==6: return redirect('content:move') else: return redirect('content:report') It takes the URL and redirects it to the active part of student either content, illustration or other. I want to make the same thing in API. How can I do so? Problem is I have certain post requests within these also. For example, a student can view the content (GET) and can give answers to some questions via POST. student.active_state changes by 1 as the student move between on part to other, for example from content to illustrations. (It becomes 1 to 2).
