Updating two fields at once with choices in django admin
I have x and y in my model as DecimalField. Something like this: class MyModel(models.Model): x = models.DecimalField() y = models.DecimalField() I want user to select these x and y from a list of dictionaries I have. It has to be selected together. As an example: [ { "x": 1, "y": 2, }, { "x": 3, "y": 4, }, ] We have two dictionaries in the example list so user should see two choices in a dropdown. Choice one with x: 1 and y: 2 Choice two with x: 3 and y: 4 Do I need to customize some widget or field for that? If I need how can I do that? -
Translation with variable is not working in django templates
I am using django translation to swith language. It is working fine but when get variable from database and try to translate in template, it's not working but it's working in views. example: msg = ugettext_noop('New van booking has been made - %(pk)d') % {'pk': booked.pk} Notification.objects.create(note_category='4', message=msg, role='Admin', booking=booked, van=van) I have also tried msg = gettext('New van booking has been made - %(pk)d') % {'pk': booked.pk} Notification.objects.create(note_category='4', message=msg, role='Admin', booking=booked, van=van) and message is as New van booking has been made - 8. I have also done makemessages and compilemessage #: .\van\views.py:563 #, python-format msgid "New van booking has been made - %(pk)d" msgstr "" "Une nouvelle réservation de van a été faite. Numéro de réservation - %(pk)d" but when I loop this in template, that does not work. {% for note in admin_note %} <span class="d-block">{% trans note.message noop %}</span> {% endfor %} it only shows New van booking has been made - 8 in all languages. But it's working in view fine. print(gettext('New van booking has been made - %(pk)d') % {'pk': 8}) Does anyone know how can I get translation in template. NOrmal translation is working fine. -
Autocomplete with API not working in Django
I am trying to autocomplete cities in Django and it is not working. I think something is wrong with my form.

A bunch more form entries ..... </form> Then we have the javascript, ajax to call the API to do the Autocomplete: function searchOpen() { var search = $("#search_city").val() var data = { search: search }; $.ajax({ url: '/api/get_city_state/', data: data, dataType: 'jsonp', jsonpCallback: 'searchResult' }); function searchResult(data) { $( "#search_city" ).autocomplete ({ source: data }); }; Here is my api function in views.py: def get_city_state(request): if request.is_ajax(): q = request.GET.get('city', '') results = search.find_city(q, best_match=False) data = request.REQUEST['callback'] + '(' + simplejson.dumps(result) + ');' else: data = 'fail' mimetype = 'application/json' return HttpResponse(data, mimetype) -

Django dynamically create not equal q objects
I'm working on creating dynamic filters using nested AND / OR logic, and would like to include NOT as an option. This leverages Q objects to create the nested AND / OR logic. The class takes in a json object like so: filters = { 'and': { "url__is": "www.test.com", "name__is": "test" } } This gets compiled down to .filter(Q(url__is='www.test.com') and Q(name__is='test') This works via a recursive function that really just does this on each level of the json tree. return source_queryset.filter(reduce(and_, filter_list)) and_ is from the python operator library and has been working great. I'd like to add NOT as an option as well though, and can't seem to find an equivalent option to reduce a list of Q objects to. Does anyone know a way to use reduce in a way that creates the idea of not equal to a list of q objects? -

DateField shows None in template, but correct date in Django Admin
I have this field in my model cancel_date = models.DateField(null=True, blank=True), but it's acting weirdly. In my admin it shows correctly with the date added, but when returning it in the template as {{model.cancel_date}}, it displays None instead. Is there a reason why that would be? -

How to to do Mask input in django?
I am working on a little app so I hope you will never mind if I ask some noob questions. I am taking a NIC number from a user but with proper format. Format: xxxxx-xxxxxx-x It means that when a user click in the input field, all the xx should remove and only - will be remains, so if a user types 17301, the - should be appear automatically and then user continue to write 362775 then a - should appear automatically and finally last digit entered by the user 6. This was the complete scenario, I hope I defined it very simple. Input Field Code <div class="col-md-3 mb-3"> <label for="validationCustom10">CNIC</label> <input type="number" class="form-control" id="validationCustom10" placeholder="xxxxx-xxxxxxx-x" name="contact" required> </div> -

stop Django admin actions from showing project wide
I've got a project with quite a few admin-actions. Currently I'm registering them like so: @admin.action(description='Some admin action description') def do_something_action(self, request, queryset): pass Some of these are being added to the admin-class of another app so I cannot simply add the function directly on the class where they are needed. The problem is that these actions are shown project-wide, on every admin-screen. How can I stop this behaviour, and manually set them where they are wanted? If it matters, it's Django3.2. -

Django update_or_create throws an error, but works properly from shell
Say I have two models which are bound by OneToOne relation. class Person(models.Model): ... class Pear(models.Model): consumer = models.OneToOneField( Person, on_delete=models.CASCADE ) color = models.CharField() ... Person ModelSerializer nests Pear ModelSerializer. Person ModelSerializer also has update method which calls update_or_create for Pear. It looks like this. class PearSerializer(serializers.ModelSerializer): class Meta: model = Pear fields = '__all__' class PersonSerializer(serializers.ModelSerializer): pear = PearSerializer(required=False) class Meta: model = Person fields = '__all__' def update(self, instance, validated_data): pear_data = validated_data.pop('pear') ... if pear_data is not None: obj, created = Pear.objects.update_or_create( consumer=pear_data.get('consumer'), defaults={'color': pear_data.get('color')} ) ... So it throws an error saying that the consumer field value should be unique. At the same time update_or_create with the same parameters and absolutely same data works perfectly if called through shell. What am I missing? Thanks. -

MySQL replication for Graphene Django
I'm using Graphene as a GraphQL server in Django. I set up a MySQL replica in Django. My setting is pretty simple. Read requests -> Replica. Write requests -> Source Mutations works in the next way: They modify data and then return modified/new data. Graphene modifies data in Source and immediately selecting them from Replica. The problem is that updated data is not immediately appearing in Replica DB (because of Replication delay). As result, some mutations simply do not work. I have a solution - specifying the Django database in every mutation. Didn't tried it yet. But the project is huge, and this requires a lot of changes in the codebase. I'm looking for simpler solutions. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'db_name', 'USER': 'root', 'HOST': MYSQL_HOST, 'PORT': '3306', }, 'read_replica': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'db_name_replica', 'USER': 'root', 'HOST': MYSQL_HOST_REPLICA, 'PORT': '3306', } } DATABASE_ROUTERS = ['app.db_router.DatabaseRouter'] class DatabaseRouter: def db_for_read(self, model, **hints): return 'read_replica' def db_for_write(self, model, **hints): return 'default' def allow_relation(self, obj1, obj2, **hints): return True def allow_migrate(self, db, app_label, model_name=None, **hints): return True -

This is problematic because instead of being able to move forward with the account creation, the user is shown an allauth default html page with a form to enter the email/username. I would like to skip this page altogether and I could if I had the email in the first place. The dictionary that I get is the "data" coming out of allauth/socialaccount/adapter.py function populate_user(populate_user(self, request, sociallogin, data). Maybe I should have the email at the different step? My settings are set up as such: LOGIN_URL = 'login' LOGIN_REDIRECT_URL = '/' LOGOUT_URL = 'logout' LOGOUT_REDIRECT_URL = 'login' SOCIAL_AUTH_RAISE_EXCEPTIONS = False ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_USERNAME_REQURIED = True ACCOUNT_AUTHENTICATION_METHOD …
