I need to open a modal if a condition is satisfied and get the post value. Is this possible in django?
In my app there are several if conditions. In one of the if condition a modal with two buttons will be shown. if the user clicks one button it should go execute a statement. If user clicks another one it should execute another statement. Is it possible in django. In my views.py def something(request): if statement: (modal should pop up in window) and from the post value from the modal another process should be done. -
Django. Pytest and Postman are getting different results on a single default value when testing
I'm starting to get into Django and pytest. I created a project with few basic components, and it all works well as designed. Except for a Pytest result The model is: class Opportunity(models.Model): class OpportunityQualityLevel(models.TextChoices): H = "High" M = "Medium" L = "Low" class StageProbability(models.TextChoices): A = "Signed Contract" B = "Verbal Confirmation" C = "Resumes First" D = "Nothing Firm" name = models.CharField(max_length=60) value = models.IntegerField() quality = models.CharField(max_length=8, choices=OpportunityQualityLevel.choices, default=OpportunityQualityLevel.M, blank=True) Stage = models.CharField(max_length=24, choices=StageProbability.choices, default=StageProbability.D, blank=True) client = models.ForeignKey(Client, on_delete=models.CASCADE) is_active = models.BooleanField(default=True, blank=True) date_created = models.DateTimeField(auto_now_add=True, null=True, blank=True) last_updated = models.DateTimeField(auto_now=True) class Meta: verbose_name_plural = "Opportunities" def __str__(self): return self.name The Serializer is: class OpportunitySerializer(serializers.ModelSerializer): class Meta: model = Opportunity fields = ["id", "name", "value", "quality", "Stage", "client", "is_active", "date_created", "last_updated"] The view is: class OpportunityViewSet(ModelViewSet): queryset = Opportunity.objects.all().order_by("name", "client", "-is_active") serializer_class = OpportunitySerializer pagination_class = PageNumberPagination The URL is: router = routers.DefaultRouter() router.register("", views.OpportunityViewSet) urlpatterns = [ path("", include(router.urls)) ] The test itself is very simple: Creating a client and assigning an opportunity from that client. The problematic field on value is the "is_active" I configured it in the model to be "True" as can be seen in the model. When testing with Postman … -
How to allow a user to add objects in Django admin based on the user that has logged in
I want to have an admin where any user who logs in to the admin dashboard can add the objects from their operator email only. Now, the user can add a package object from another operator email as well. I don't want a user to add objects under the email of another operator's email. My Models: class UserProfile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, related_name='profile', on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) user_type = models.CharField(max_length=1, choices=USER_TYPES, default='g') first_name = models.CharField(max_length=255, default="") def __str__(self): return self.user.email class Package(models.Model): operator = models.ForeignKey(UserProfile, on_delete=models.CASCADE) destination = models.ForeignKey(Destination, on_delete=models.CASCADE) package_name = models.CharField(max_length=255) city = models.CharField(max_length=255) My package/admin.py: class PackageAdmin(ModelAdmin): icon_name = 'explore' autocomplete_fields = ['destination'] list_display = ('package_name', 'featured', 'price', 'discounted_price', 'savings', 'fix_departure', 'rating', 'date_created',) def get_queryset(self, request): abc = super(PackageAdmin, self).get_queryset(request) if request.user.is_superuser: return abc else: operator = request.user.profile return abc.filter(operator=operator) Here in the above image we can see that a user can add an object under another operator's email as well. I dont want that. The two solutions will be: Only the current user/profile visible in operator field. Although the emails are visible, cant add the package under another operator's ema -

How to make docker-compose django server run on local wifi network, so our iOS developer can test the API from the iPhone device?

Grouping by date intervals of multiple datetime columns
I have a queryset that I want to group by months, quarters, and years. However, instead of just grouping based on one datetime field of a model, I would want to group by several datetime fields. E.g., I have sign ups for multiple event types (different models) and each of them has a date associated with the sign up. Now, I would like to find how many sign ups I have in total for each month. I used Coalesce(TruncMonth(x), TruncMonth(y), TruncMonth(z)) but that only groups on the first none null field. Is there any other way? -

How do i Fix django.db.utils.DatabaseError
How do i fix Django Database error. I'm using MongoDB with Djongo. Everything was working fine until recently when i decided to add NewApp. Whenever i try to migrate it greets me with django.db.utils.DatabaseError .

Django, Many-to-one relationship with Abstract entities
Say object contains multiple types of objects (Models) in an array, like a Page, that could contain a Post, Blog, Picture, in any quantity or order, where the user scrolls down and sees the following element and that depending on the page, is next element one of these types of elements. Thus a Page could contain: A Post A Post A Picture Or something pretty different such as: A Picture A Blog A Picture An element could be an abstract entity that has an attribute as a ForeignKey relating itself with Page, and its inheritance would gain access to that relationship: class Page(models.Model): ... class PageElement(models.Model): page = models.ForeignKey(LandingPage, verbose_name="Page", on_delete=CASCADE) class Meta: abstract = True class Post(PageElement): ... class Blog(PageElement): ... class Picture(PageElement): ... With this approach, you can serialize Page with a REST serializer, but you wouldn't have access to an pageElement_set, instead you would need to call post_set, blog_set, picture_set and loose the order of the objects. The question is: How do you implement such relationships in Django? So that you can have an order set of PageElement instances, and be able to have the desired order. -

Django REST on Local Network
I know this is probably not the best place to ask but I can't seem to find a better one so here goes... I want to set up a local system using DJango REST and react.js/native as the UI for accessing the API on the same network e.g. a tablet which is fed a PWA would be fine. The server exists in-house and I do not want it connected to the web. Is it possible to deploy a production site from a local server and have it accessed only locally? It seems like it should be possible. If it is, how do you go about handling Https/SSL? I see self-signed certs but everywhere says not to use them on a production system. Can someone give me advice on how I can make this secure/possible? Edit: I should add that I would want to use Apache web server. -

How to generate multiple Dash App (and URLs) programmatically?
I have a simple Dash app with a choropleth map along with a simple dropdown. The data is sourced from a pandas dataframe and contains a few different metrics for each US state. I'd like to reproduce this standard layout for each of the US state but here's the problem: I'd like to avoid having to create 50 different dash apps (it doesn't look really practical neither scalable) I don't want to have a dropdown for users to select the state: the goal is to have multiple URLs, one for each state (mostly for search engine purposes). I was thinking of passing the US state as a URL parameter: I'd use this variable to filter the dataframe (limiting the dataframe scope will automatically make the choropleth zoom to the relevant state). However this is problematic since: Dash doesn't allow to set a default base URL for the app (at least as far as I could tell) The df cleaning/filtering happens before I can call the flask instance in Dash (this would be easily solvable though) as well as the app URL. I wanted to do this all within Dash for practicality but I guess I'd need to rely on Flask/Django … -
Django Allauth integration with Django CMS
I'm using DjangoCMS and AllAuth on a website I'm working on - I'm trying to get Django CMS to automatically send you to AllAuth's login page, instead of it's own admin page. Here's my current urls.py file: urlpatterns = [ path("sitemap.xml", sitemap, {"sitemaps": {"cmspages": CMSSitemap}}), path('en/accounts/', include('allauth.urls')), ] urlpatterns += i18n_patterns(path("admin/", admin.site.urls), path("", include("cms.urls"))) The issue is that DjangoCMS, when it's grabbing the admin page to show, using namespacing to get admin:login. Now, my thought was I can just have the namespace admin refer to AllAuth - but AllAuth doesn't support namespacing. Is there any way to either: Have that automatically redirect to AllAuth? I'd think it might be possible to have the default admin's page redirect in the view itself, but I'd rather not try to change the built in Django code Have that namespace get sent to a specific URL, even if AllAuth doesn't support it by default. Thanks! -

GenericViews - and pushing model name in URL
using Django Generic CreateView - is it possible for me to pass a value into the CreateView from the URL call, that defines which model/table to base the view on? I did try get_context_data but believe that is not the solution, as I think it only pushes it to the rendered template. You will see from my scripts - I am pushing the value 'syslog_policy' - i would like the view to set the model variable to be, what-ever value I push from the URL. The reason for this, I have some pages/models that are similar - so rather than create multiple html pages and views - I wouldn't need to if I could get this to work. URL Call <li><a href="{% url 'security_app:HardenTemplateCreate' 'syslog_policy' %}">Update/Delete Policies</a></li> urls.py path('HardenTemplateCreate/<str:element>', HardenTemplateCreate.as_view(success_url="/security_tooling/add_success") ,name="HardenTemplateCreate") views.py def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['element']= self.kwargs['element'] print(context['element']) return context model = !!<NEED VALUE SUPPLIED IN URL HERE>!! fields = ['name','template'] template_name = 'security_app/add.html'``` -
Generating audio files in a Django project template

Django 3.1 bug: Reflexive Many-to-many relations. Add creates two relationships instead of one
in the model called Business: sold_at_businesses = models.ManyToManyField('self', db_table='businesses_to_sold_at_businesses', related_name='businesses_selling') test code - ms is a Business instance. ms.sold_at_businesses.clear() b = Business.objects.get(slug="test-business") if b: ms.sold_at_businesses.add(b) Bug: This single add call adds two entries to the pivot table. m -> b and b -> m Why are two connections being created when I clearly specify only one? this seems like a reflexive model bug in Django. -
How to set dynamic attributes in django rest framework serializers?
I have some json in the following format: { "daySchedules": { "500000004061582000": { "scheduleName": "Friday-Sunday", "services": [ { "name": "Lunch", "hours": { "startTime": "12:00:00.000", "endTime": "16:00:00.000" }, "overnight": false }, { "name": "Dinner", "hours": { "startTime": "17:00:00.000", "endTime": "23:00:00.000" }, "overnight": false } ], "openTime": "12:00:00.000", "closeTime": "23:00:00.000" }, "500000004061559163": { "scheduleName": "Tuesday-Thursday", "services": [ { "name": "Breakfast", "hours": { "startTime": "04:00:00.000", "endTime": "11:00:00.000" }, "overnight": false }, { "name": "Lunch", "hours": { "startTime": "12:00:00.000", "endTime": "16:00:00.000" }, "overnight": false }, { "name": "Dinner", "hours": { "startTime": "17:00:00.000", "endTime": "20:00:00.000" }, "overnight": false } ], "openTime": "04:00:00.000", "closeTime": "20:00:00.000" } }, "weekSchedule": { "monday": null, "tuesday": "500000004061559163", "wednesday": "500000004061559163", "thursday": "500000004061559163", "friday": "500000004061582000", "saturday": "500000004061582000", "sunday": "500000004061582000" } } The attributes in the json 500000004061582000 and 500000004061559163 is dynamic and determined by what's returned in the weekSchedule. I wish to create the following serializers: class ScheduleForDaySerializer(serializers.Serializer): schedule_name = serializers.CharField() services = serializers.ListField() open_time = serializers.CharField() close_time = serializers.CharField() class WeekScheduleSerializer(serializers.Serializer): monday = serializers.CharField(allow_null=True) tuesday = serializers.CharField(allow_null=True) wednesday = serializers.CharField(allow_null=True) thursday = serializers.CharField(allow_null=True) friday = serializers.CharField(allow_null=True) saturday = serializers.CharField(allow_null=True) sunday = serializers.CharField(allow_null=True) class DaySchedulesSerializer(serializers.Serializer): # what comes here? class SchedulesSerializer(serializers.Serializer): day_schedules = DaySchedulesSerializer() week_schedule = WeekScheduleSerializer() I'm struggling to determine how …
