Highlight entire row in Django admin list
I've been stuck on this issue for days. I have a change_list with applicants, now I want to highlight the rows of objects that have been changed recently. To do this I made a custom property: @property def has_recently_been_modified(self): return datetime.now() - self.updated_at < timedelta(days=5) Which I use in the admin.py to create a field that houses a class I need: def recently_modified(self, obj): if obj.has_recently_been_modified: return mark_safe("<span class='row_yellow'></span>") recently_modified.allow_tags = True list_display = ('custom_status','viewed', 'updated_at', 'first_name', 'last_name', 'vacancy', 'created_at', 'recently_modified') And with JS I use that class to color the row: window.onload = function () { const x = document.getElementsByClassName("row_yellow"); let i; for (i = 0; i < x.length; i++) { let ligne = x[i].parentNode; while (ligne.tagName !== "TR") { ligne = ligne.parentNode; } ligne.style.backgroundColor = "yellow"; } } Although it does color the entire row, the extra empty column at the end of the row is a real thorn in my eye. Removing it from the list_display doesn't obviously work. So my question is, is there a clever way to "hide" it? Or even a completely different method to color the row? I have tried using django-liststyle, but that seems like a broken package. I immediatly get a … -
How to test an OTP-secured Django form?
I'm building a Django application using the django_otp OTP extension, and I'm running into some issues with automated testing of forms. Specifically, despite everything I've tried, attempts to call a form decorated with otp_required results in getting shown the 'you need to enable OTP on this account' redirect page. I've made several attempts at implementing things suggested by google searches, such as this one and several others. Right now, during the TestCase __init__ I create a user with the following code: # Set up a user: self.testuser = User.objects.create(username='testuser') self.testuser.set_password('12345') self.testuser.is_superuser = True self.testuser.is_verified = True self.otp_device = self.testuser.staticdevice_set.create(name='Testdevice') self.otp_device.confirmed = True self.otp_device.save() self.testuser.save() And when using a Client object to make a request: def setup_client(self): client = Client() client.force_login(self.testuser) client.session.save() return client The failing test case is: def test_connection_create_form_no_circuit(self): testdata = baseData() client = testdata.setup_client() client_group = ClientGroup.objects.get(name='testgroup') context_id = Context.objects.get(name='testcontext').id bandwidth_id = BandwidthProfile.objects.get(name='testprofile').id conntype_id = ConnectionType.objects.get(name='testconntype').id postdata = { 'id_enabled': True, 'id_circuitless': True, 'id_debug_info': False, 'id_connectionref': 'Test 1234', 'id_customer': '321', 'id_install_address': '123 Stockton Bvd.', 'id_carrierref': 'nil', 'id_c_context': context_id, 'id_c_bandwidthprofile': bandwidth_id, 'id_c_connectiontype': conntype_id, 'id_ppp_username': 'test_conn_123', 'id_ppp_password': 'pass_54321', 'id_ipv4_address': '1.2.3.4' } response = client.post('/radius/clientgroup/%d/connection/' % client_group.id, postdata) self.assertEqual(response.status_code, 200) Rather than a 200 I'm getting a 403 and the 'You … -
What should a django view that processes the post request from esp32 look like
I have a challenge sending data from esp32 to my django server. I am using HttpClient and my site is hosted on ngrok.

Returning data to Django form for editing
I am using multiple forms which opens in modals from the same page at my Django app. I got it to work with custom functions, but now I'm a bit struggling on how to add editing functionality since I am very new to Django. Since this way working with forms is very new to me I got lost where should I provide instance that form would show already entered data for that instance. This is form variable in views.py edit_employment_form = _get_form(request, EditEmploymentForm, "edit_employment_form_pre") This is function I use to differiante between forms. (Or at least i think that this does it) def _get_form(request, formcls, prefix): data = request.POST if prefix in request.POST else None return formcls(data, prefix=prefix) This is my full view in views.py to better understand structure. Below request.method condition is variable employment_id which I am going to use to filter instance. I get that id from button in html which itself is form and returns me item id from for loop. @login_required def person_profile(request, person_id): current_user = request.user user = Person.objects.get(user=current_user) people = Person.objects.all() jobs = Job.objects.all() person = Person.objects.get(pk=person_id) employments = Employments.objects.filter(person_id=person_id).order_by("-start_date") workflows = Workflows.objects.filter(person_id=person_id).order_by("-workflow_date") sources = Sources.objects.filter(person_id=person_id).order_by("-source_date") tags = Tags.objects.filter(person_id=person_id) comments = Comments.objects.filter(person_id=person_id) person_calls = … -

request.session[] doesn't work on mobile phone (chrome) but works on desktop. Why?
I've made a store and it is super strange, it works on desktops and iPads without any bugs but when I check it on my mobile phone it has a strange bug. The bug is: There are a store page and the cart page. I add the first item to request.session[] on the "store page", I go to "cart page" and I see that the item is there, right from the request.session[]. Then I go back to the "store page" and add another item. I go back to the "cart page" again and I don't see the second item in the cart! I can click the "cart" link again and again. And there will not be the 2nd item. I can go to another page and then go back to the "cart" page again, and there will not be the 2nd item, but if I just refresh the page - the item will appear. Why? Why do I need to refresh the page, even going back and forward doesn't work, but only refreshing works... After refreshing it shows all items from the request.session[]. I really can't understand how it can be. Do you have a clue? I wanted to connect … -
