Passing JSON from custom view to template
So I have worked with a Django program that was working before, got some code got lost and I managed to recover the most, but have some issues left. I have a class that's building different dictionaries that are supposed to be passed on to the frontend, where there are some Javascript function that's work with that data. My problem is I can't get the pass the data from the view to the template. I have tried to use HttpResponse, but then it just displays the data on a blank screen. I just want to pass it to the template and let the JavaScript functions there work with it. class ReportDashboardView(AuthMixinLineManager, ReportDashboard, generic.TemplateView): """Team report view, build data required for graphs and tables.""" template_name = 'index.html' http_method_names = ['get'] def get(self, request): data_left, data_joined, data_changed_team = self.init_report() data_left = json.dumps(data_left) return HttpResponse(json.dumps(data_left), content_type="application/json") Looks like this I instead just want to "feed" the data to the already existing HTML-template and use the escapejs to access the data that comes from the view. I know the URL-patterns is correct. And here is a example of how the JavaScript functions looks. So my questions is, does anyone have any suggestion on how … -
How to filter many2many field with another many2many?
I have following model in my Django: class Filter(models.Model): min_price = models.PositiveIntegerField(null=False, blank=False) max_price = models.PositiveIntegerField(null=False, blank=False) trait = models.ManyToManyField(Trait, null=True, blank=True) class Flat(models.Model): living_area = models.DecimalField(max_digits=7, decimal_places=2, null=True, blank=True, db_index=True) trait = models.ManyToManyField(Trait) class Trait(models.Model): name = models.CharField(max_length=255, blank=False, null=False, db_index=True) In my case trait can be for example: elevator. If there is connection between Flat and Trait(name="Elevator") then I can assume that Flat has elevator. What I want to do is to searching flats based on traits - traits from Flat and traits from Filter should be the same. I did somethink like this: filte_obj = Filter.objects.get(pk=pk) flat = Flat.objects.filter(trait__id__in=[x.id for x in filter_obj.trait.all()]) Unfortunately I does not work as I want. I want to see only Flats which Traits QuerySet is the same as Filter's traits QuerySet. How can I do that? -
How can I filter out static logs on Heroku Papertrail for a Django App?
I am trying to filter out logs related to static files on a Heroku/Django App. Based on this answer django - how to filter out GET static and media messages with logging? I added the following code snippet in settings.py def skip_static_requests(record): if record.args[0].startswith('GET /static/'): # filter whatever you want return False return True LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { # use Django's built in CallbackFilter to point to your filter 'skip_static_requests': { '()': 'django.utils.log.CallbackFilter', 'callback': skip_static_requests } }, 'formatters': { # django's default formatter 'django.server': { '()': 'django.utils.log.ServerFormatter', 'format': '[%(server_time)s] %(message)s', } }, 'handlers': { # django's default handler...

Why is Django giving me a ValueError when I reference a class within the same model?
I'm building a simple recipe app, and so far I have two models: Ingredient and Recipe. Each recipe should have multiple ingredients, so I laid out my model like this: class Ingredient(models.Model): name = models.CharField(max_length=50) class Recipe(models.Model): title = models.CharField(max_length=100) ingredients = models.ForeignKey(Ingredient, on_delete=CASCADE) instructions = JSONField() date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, on_delete=SET_DEFAULT, default='Chef Anon') When I makemigrations, I get nothing, but when I migrate, I get this ValueError: ValueError: Cannot alter field cookbook.Recipe.ingredients into cookbook.Recipe.ingredients - they do not properly define db_type (are you using a badly-written custom field?) Following the example here (Django: Add foreign key in same model but different class), I've tried setting ingredients=models.ForeignKey(Ingredient, on_delete=CASCADE) as well as using lazy syntax ingredients=models.ForeignKey("Ingredient", on_delete=CASCADE), but each time, makemigrations shows no changes, and migrate gives me the same ValueError. -
Django Multilanguage - allow users to translate their own input
I'm writing a multilanguage application for renting out property. I've succesfully translated all of the static content inside my application, but the input that the user gives is dynamic and needs to be translated by them. Example: The user needs to create all the different rental types that are available for a client to choose from. However, for each language this type has a different name because it needs to be translated. Ideally, when creating a rental type, the user should see multiple input fields for the name: one for each language. Django should then determine by the client's language which name to show. I've tried using django-modeltranslation and that created some extra columns on my database, but I cannot find a way for a user to edit all of these columns from one view. This is my translation.py # translation.py from modeltranslation.translator import register, TranslationOptions from .models import RentalType, Costs @register(RentalType) class RentalTypeTranslationOptions(TranslationOptions): fields = ('type', 'slug') @register(Costs) class CostTranslationOptions(TranslationOptions): fields = ('name',) Which were succesfully migrated to my database: Migrations for 'main': main\migrations\0014_auto_20211202_1559.py - Add field name_en to costs - Add field name_fr to costs - Add field name_nl to costs - Add field slug_en to rentaltype - … -

Django rest framework upload nested form data
I have a front end react.js app that send a form data to a django rest framework end point. Basically, I want to create an order that consists of multiple ads, for now I am testing it using one ad.

How to customize the admin form for a custom image model in Wagtail CMS?
I need to add a string based unique ID to Wagtail’s image model. These IDs are a relatively short combination of letters, numbers and punctuation, e.g. "AS.M-1.001". So I am using a custom image model with Django’s standard CharField for that with the argument unique=True. But the editing form unfortunately does not check if the ID is unique. So I can use the same ID for multiple images. This check for uniqueness does work in any other standard form in Wagtail, e.g. the Page model. But not for the image model. from django.db import models from wagtail.images.models import Image, AbstractImage class CustomImage(AbstractImage): custom_id = models.CharField(max_length=32, unique=True, null=True, blank=True) admin_form_fields = ( 'custom_id', ) + Image.admin_form_fields My approach would be to override the editing form with a custom one to display more warnings and errors, like you can do with base_form_class for Wagtail’s Page model etc., as documented here. I tried both wagtail.admin.forms.WagtailAdminModelForm as well as wagtail.images.forms.BaseImageForm. from wagtail.images.forms import BaseImageForm from wagtail.admin.forms import WagtailAdminModelForm class CustomImageForm(WagtailAdminModelForm): # add more logic here pass class CustomImage(ArtButlerIDMixin, AbstractImage): ... base_form_class = CustomImageForm Both lead to the same exception: raise AppRegistryNotReady("Models aren't loaded yet.")

Using a GIN index in Django which was created in postgreSQL
I have created a model in Django. class MyModel(models.Model): features = TextField(blank=True, default='') There are several possible ways to store the data in the feature field. Some examples below. feature1;feature2 feature1, feature2 feature1,feature2 And so on. I created a GIN index for that field. That's postgreSQL code I used inside migrations.RunSQL. CREATE INDEX features_search_idx ON "mymodel" USING gin (regexp_split_to_array("mymodel"."features", E'[,;\\s]+')); The migration worked and I managed to find that index using, for example, \di+ mymodel_features_search_idx. Now I would like to use that created index to filter my queryset. I thought something like the code below would work MyModel.objects.annotate(F('features_search_idx')).filter(features_search_idx__in=['Feature1', 'Feature2', 'Feature3'].count() Unfortunately an error occurred django.core.exceptions.FieldError: Cannot resolve keyword 'feature_search_idx' into field..
