Django check if any attr matches in a query
I have a "search" form, which searches for objects from my DB. This form has two fields, a Select (ChoiceField) where users can select which attribute they are searching by, and a text field they can fill. For example I can select "Search by name", and I type "Matt", so it will search for value "Matt" on column "name". Also I can search by other attrs. Everything work fine until here. The problem comes when I try to use my last search option, "Search by any coincidence", which should query for a match in any of the columns. forms.py: class BuscarAuxi(forms.Form): busqPor = forms.ChoiceField( required=False, widget=forms.Select, choices=SEARCH_AUXI, ) criterio = forms.CharField(max_length=100) busqPor.widget.attrs.update({'class': 'form-control'}) criterio.widget.attrs.update({'class': 'form-control col-7 m-2', 'placeholder': 'Criterio'}) views.py: def crudAuxi(request): if request.method == "GET": form = BuscarAuxi(request.GET) print('Entra a GET de BuscarAuxi. ') print(form.errors) if form.is_valid(): print('El formulario GET de BuscarAuxi fue válido. ') print(form.cleaned_data.get('busqPor')) critBusqueda = form.cleaned_data.get('criterio') tipoBusqueda = form.cleaned_data.get('busqPor') if tipoBusqueda == '1': try: busqueda = Auxi.objects.get(denom=critBusqueda) if busqueda: print('Encontró por nombre.

How to test a `admin.site.login` changing in the middle of a test
I'm using a global setting to optionally change the admin.site.login value in an admin.py within my app: if settings.DJANGO_ADMIN_FORCE_ALLAUTH: # Enforce /admin to go through django-allauth for login admin.site.login = decorators.login_required(admin.site.login) And I'm testing as follows: import sys from importlib import reload from django.test import LiveServerTestCase, override_settings from django.urls import reverse from django.contrib.admin import sites from selenium.webdriver.firefox.webdriver import WebDriver class AdminTestCase(LiveServerTestCase): @classmethod def setUpClass(cls): super().setUpClass() cls.selenium = WebDriver() cls.selenium.implicitly_wait(10) @classmethod def tearDownClass(cls): cls.selenium.quit() super().tearDownClass() @override_settings(DJANGO_ADMIN_FORCE_ALLAUTH=False) def test_admin_allauth_workflow_disabled(self): # This raises an expected `AlreadyRegistered` error try: reload(sys.modules['my_app.users.admin']) except sites.AlreadyRegistered: pass self.selenium.get(f'{self.live_server_url}{reverse("admin:index")}') self.assertEqual(self.selenium.current_url, f'{self.live_server_url}{reverse("admin:login")}?next={reverse("admin:index")}') @override_settings(DJANGO_ADMIN_FORCE_ALLAUTH=True) def test_admin_allauth_workflow_enabled(self): # This raises an expected `AlreadyRegistered` error try: reload(sys.modules[my_app.users.admin']) except sites.AlreadyRegistered: pass self.selenium.get(f'{self.live_server_url}{reverse("admin:index")}') self.assertEqual(self.selenium.current_url, f'{self.live_server_url}{reverse("admin:login")}?next={reverse("admin:index")}') I'm only using selenium so I can see the output myself, it's really not necessary for this test. I'm forcefully reloading the admin module so that my optional code gets called when I override the settings, but the admin.site.login is still returning the same. Right now, test_admin_allauth_workflow_disabled works and test_admin_allauth_workflow_enabled shouldn't work (since they're identical just with a changed setting), but they both work. What else do I need to reload in order for the admin.site.login value to be updated? If I put my settings in separate files, or separate … -

Deploying gunicorn with upstart, thwarted by import error
I'm trying to configure gunicorn 19.9.0 (Ubuntu 14.04) with upstart, but I keep getting an import error in /var/log/upstart/gunicorn.log. The error is ImportError: cannot import name Celery. However, this module is installed in my virtualenv. E.g. if type celery when myenv is activated, I get the module's usage help. Hence there's this possibility that gunicorn.conf is not being run from inside the correct virtual env. That's perplexing because I've triple checked my config - I believe the error is elsewhere. Here's the config: description "Gunicorn application server handling my server" start on runlevel [2345] stop on runlevel [!2345] respawn setuid ubuntu setgid www-data chdir /home/ubuntu/myapp/myproj/ exec /home/ubuntu/.virtualenvs/myenv/bin/gunicorn --chdir=/home/ubuntu/myapp/ -w 3 --timeout 60 --bind unix:/home/ubuntu/myapp/myproj/myproj.sock myproj.wsgi:application The traceback produced in /var/log/upstart/gunicorn.log is as follows: [2019-01-31 13:16:16 +0000] [5898] [INFO] Booting worker with pid: 5898 [2019-01-31 13:16:16 +0000] [5898] [ERROR] Exception in worker process Traceback (most recent call last): File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/arbiter.py", line 583, in spawn_worker worker.init_process() File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/workers/base.py", line 129, in init_process self.load_wsgi() File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/workers/base.py", line 138, in load_wsgi self.wsgi = self.app.wsgi() File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/app/base.py", line 67, in wsgi self.callable = self.load() File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 52, in load return self.load_wsgiapp() File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/app/wsgiapp.py", line 41, in load_wsgiapp return util.import_app(self.app_uri) File "/home/ubuntu/.virtualenvs/myenv/local/lib/python2.7/site-packages/gunicorn/util.py", line 350, in … -

Architecture of a CBV with the ability to optionally load blocks with AJAX
I have a view that reponds with a very large response. Many templates involved, many variables, a lot of data, a lot of JS code to be executed. I have tried optimizing templates and queries the best I could but I feel I have reached a limit. The loading time is acceptable for smaller objects, but when bigger ones are involved it gets very bad. Therefore I have thought about using pagination and the like. My question is about the architecture of the CBV to implement optional AJAX handling. Let me explain: The idea is to set up the view and the most relevant templates or slower blocks so that when the object is too big, the block is requested asynchronously instead of including it in the main request: some_template.html <div id="content-a"> {% if object.is_big %} <script> $(function () { $.get(contentAURL, function (data) { $('#content-a').html(data); }); }); </script> {% else %} {% include 'content-a-template.html' %} {% endif %} </div> And in the view we would fetch the necessary data depending on what we need: # this would be the main CBV def get_context_data(self, *args, **kwargs): context = super(ScheduleMakerView, self).get_context_data(**kwargs) if not self.object.is_big: context['content-a-related'] = self.object.content_a.select_related().prefetch_related('users') # etc... So when the … -
How do I convert a string, represented as a list in MySQL database to a list in Django Template, so that I can iterate over it?
I have stored a list of mailing addresses in the MySQL database like ['1212 Los Angeles, CA', 'Nariman Point, Mumbai, India']. I expect to print each element of the list in my HTML template. Unfortunately, each character is being printed. Now, when I try to iterate over the list, in the Django template, I get each character instead of each list element. I have tried the Django library, django-mysql to implement native JSONField. Tried building a list in Django template, using in-built template filters, with, cycle, as list, among others. ` <div class="container"> {% if my_requests_queryset and my_requests_queryset|length > 0 %} {% for req in my_requests_queryset %} <div class="row mb-1"> <div class="col-lg-2"></div> <div class="col-lg-8"> <a href="#" class="card-link"> <div class="card text-center"> <div class="card-header"> {{ req.title|title|truncatechars:36 }} </div> <div class="card-body"> <h5 class="card-title"> {% for address in req.locations %} {{ address }} {% endfor %} </h5> </div> </div> </a> </div> </div> {% endfor %} {% endif %} </div>` I expect to print each element in a list as: 1212 Los Angeles, CA Nariman Point, Mumbai, India -
Override form field validation django
I have a Device for which many Scans are associated and are created via a form. class Device(models.Model): uuid = models.UUIDField(primary_key=True, verbose_name="UUID") # fields omitted for brevity class Scan(models.Model): device = models.ForeignKey(Device, null=True, on_delete=models.SET_NULL) When a Scan is submitted via form, the UUID of the Device is included in the POST data. If the UUID exists, the Scan will be associated with the existing Device, otherwise a new Device will be created and the Scan associated with that. I am using generic forms: class DeviceForm(ModelForm): class Meta: model = Device class ScanForm(ModelForm): class Meta: model = Scan The view in question is this: @login_required def scan_test(request): if request.method == 'GET': device_form = DeviceForm() scan_form = ScanForm() # otherwise create a form instance and populate it with request data: elif request.method == 'POST': device_form = DeviceForm(request.POST) scan_form = ScanForm(request.POST, request.FILES) # is_valid is determining that UUID is not unique if device_form.is_valid() and scan_form.is_valid(): form_data = device_form.cleaned_data try: device = Device.objects.get(uuid=form_data['uuid']) except Device.DoesNotExist: device = Device( uuid=form_data['uuid'], ) device.save() scan = Scan(device=device, data=scan_form.cleaned_data['data']) scan.save() return HttpResponseRedirect(device.get_absolute_url()) return render(request, 'app/scan_form.html', {'device_form': device_form, 'scan_form': scan_form}) Creation of a new Device and associated Scan works OK.

How to fix "image not being saved into my database(i.e image model field)"?
I am building a Portfolio web app with Django. I am unable to save an image into my database in my web app. Also, to replace an existing image in the database does not work.
