How to handle UniqueConstraint failure in Django Meta Class?
I have created a UniqueConstraint Meta Class for my model, and it works when I test it by intentionally creating a duplicate but I am getting an error page instead of being redirected back to the original page. Where do I insert the code to go back to the page that I was just on? I assume the issue is in the view, but I have no idea what code to put in there and the Django docs contain nothing alluding to this problem. Model: class StudentScheduledClass(models.Model): student = models.ForeignKey("users.User", on_delete=models.CASCADE, db_column="Student") scheduled_class = models.ForeignKey("ScheduledClass", on_delete=models.CASCADE, db_column="ScheduledClass") grade = models.FloatField(db_column="Grade", blank=True, null=True) class Meta: managed = True db_table = "StudentScheduledClass" verbose_name_plural = "StudentsScheduledClasses" constraints = [ models.UniqueConstraint(fields=['student', 'scheduled_class'], name='student scheduled class restraint') ] View: class StudentScheduledClassCreateView(LoginRequiredMixin, CreateView): model = StudentScheduledClass context_object_name = "student_scheduled_class" fields = ["student"] def form_valid(self, form): scheduled_class = self.kwargs["scheduled_class"] form.instance.scheduled_class = ScheduledClass(scheduled_class) return super().form_valid(form) def get_success_url(self): scheduled_class = self.kwargs["scheduled_class"] return reverse("scheduled-class-detail", args={scheduled_class}) I'd like to just go back to the original page with an error message, instead I get this traceback: IntegrityError at /classes/student_scheduled_class_create/1/ UNIQUE constraint failed: StudentScheduledClass.Student, StudentScheduledClass.ScheduledClass Request Method: POST Request URL: http://localhost:8000/classes/student_scheduled_class_create/1/ Django Version: 2.2.2 Exception Type: IntegrityError Exception Value: UNIQUE constraint failed: StudentScheduledClass.Student, … -
How to disable django registration password helpt_tetxt

Design solutions for multiple Django forms for POST form fields
I have a template page for multiple forms. The user chooses the form of choice and it is rendered. After the form is filled out the user submits it and the data goes through to a POST. At the moment the code has a long amount of if/else implementation that links what the form is to the POST. Right now, if I were to add a new form, I have to update my function that helps the user choose a form and renders that form. In addition, I have to update my function that sends a POST request for that specific form. I'm looking for a better design solution so I won't have to update both functions every time a new form is added. My current implementation follows this scheme... My form selector function if type is FormA return formA() //render elif type is FormB return formB() ... My form fill function if type is FormA return formA(request.POST) elif type is FormB return formB(request.POST, request.FILES) ... -
pages' + button for drop down menu gone after applying theme
I am using Mezzanine and in the admin page, when I go to "pages" each row doesn't show me options to make lower hierarchy page. For instance, from what I remember there was a button like Add.. it allowed me to make each row's expanding item pages. I still have some rows that still have this "drop down" and still working but further creation seems to have been somehow blocked. I downloaded some themes and just extracted it to my mysite folder (and it works) but I think maybe it affected the behavior of the admin website? How can I fix this? Thank you for your answer in advance. -

How to create a collapsable form in Django with JQuery?
I am trying to create a collapsible form in Django which would toggle a form once a button is clicked.

Django queryset: order_by ForeignKey boolean attribute
I'm trying to order a queryset so that: the first elements of the queryset are those which have a ForeignKey boolean attribute (first) set to True, and amongst them, they are ordered by creation date the following elements are those having ForeignKey first attribute set to False, and again amongst them, they are ordered by creation date Here is an example of the models: class A(models.Model): first = models.BooleanField(blank=False, default=False) class B(models.Model): a = models.ForeignKey(A) created = models.DateTimeField(auto_now_add=True) The queryset looks like: queryset = B.objects.all().order_by("-a__first", "-created") This snipper, however, is not doing the work. A solution that I'm thinking of is to use two different databases call (one filtering for a__first=True and the other filtering for a__first=False), and then sum up the querysets results. But I would like to understand if there is a better and cleaner way of solving this problem. -
Django : Storage of unique, important and frequently changing constants

Send logging messages with sentry for loggers with propagate false
I'm using django and sentry-sdk. In my django settings' logger section I have the following handler: 'loggers': { 'my_module': { 'level': 'WARNING', 'handlers': ['console', ], 'propagate': False } } And the sentry-sdk is initialized as follows: import logging import sentry_sdk from sentry_sdk.integrations.django import DjangoIntegration from sentry_sdk.integrations.logging import LoggingIntegration sentry_logging = LoggingIntegration( level=logging.INFO, event_level=logging.ERROR ) sentry_sdk.init( dsn="...", integrations=[DjangoIntegration(), sentry_logging], ) However, the following example does not send an error event to sentry import logging logger = logging.getLogger('my_module') logger.error('Why do I not appear in sentry?') On the other hand, others do, as for example import logging logger = logging.getLogger('another_module') logger.error('Why do I not appear in sentry?') Question: How can I fix this for modules with propagate=False? -

Django Template - Regroup and order by number of items in the re grouping?
Im regrouping a query set in a template and I then want to order the grouped results by how many items are in each group. printing our the regrouped list I get the below data: GroupedResult(grouper=<CircuitType: FTTC>, list=[<DeviceCircuitSubnets: DeviceCircuitSubnets object (7406)>]), GroupedResult(grouper=<CircuitType: DSL>, list=[<DeviceCircuitSubnets: DeviceCircuitSubnets object (7415)>, <DeviceCircuitSubnets: DeviceCircuitSubnets object (7321)>]), GroupedResult(grouper=<CircuitType: 4G>, list=[<DeviceCircuitSubnets: DeviceCircuitSubnets object (7412)>, <DeviceCircuitSubnets: DeviceCircuitSubnets object (7413)>, <DeviceCircuitSubnets: DeviceCircuitSubnets object (7414)>])] So looking at the above there are 1 x FTTC item, 2 x DSL items, and 4 x 4G items. Id then like the groups to be put in the order below when displayed in the template 4G,DSL,FTTC does anyone know if this is possible to do? Thanks -

How to use pg_restore with AWS RDS correctly to restore postgresql database
I am trying to restore my Postgresql database to AWS RDS. I think I am almost there. I can get a dump, and recreate the db locally, but I am missing the last step to restore it to AWS RDS. Here is what I am doing: I get my dump $ pg_dump -h my_public dns -U myusername -f dump.sql myawsdb I create a local db in my shell called test: create database test; I put the dump into my test db $ psql -U myusername -d test -f dump.sql so far so good.

Is there any way to get primary key using record when creating tables in django_tables2
I'm trying to get the primary key of my table in tables.py using django-tables2 by using the variables record.pk.

How to manage 2 settings files in Django by using Honco app?
My question is based on the following existing question: Django: How to manage development and production settings?

Question is , in *.env file what exact code should I write to use for example following settings file: “myproject.production_settings.py” something like this? DJANGO_SETTINGS_MODULE=myproject.production_settings or it should be different somehow? Thank you!
