Django not finding static js scripts in the correct folder
I've already run collectstatic and created the static directory in my urls.py, and all other static files work fine (bootstrap, the custom CSS) and other scripts in the same directory work perfectly fine. This is the error code in the console. Failed to load resource: the server responded with a status of 404 (Not Found) ... jquery.formset.js:1 (http://localhost:8000/static/js/django-dynamic-formset/jquery.formset.js) (index):86 Uncaught TypeError: $(...).formset is not a function at (index):86 This is the script section from the rendered html For the second error, I've run into a similar problem before. Moving the jQuery CDN tags above the script itself solved the issue then, but it's not working now. This is my root urls.py urlpatterns = [ path('admin/', admin.site.urls), path('showroom/', include('showroom.urls')), path('', RedirectView.as_view(url='/showroom/', permanent=True)), # Redirect homepage to showroom path('accounts/', include('allauth.urls')), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) if settings.DEBUG: urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) settings.py # Static and media files STATIC_URL = '/static/' STATIC_ROOT = ( os.path.join(BASE_DIR, 'static') ) MEDIA_URL = '/media/' MEDIA_ROOT = ( os.path.join(BASE_DIR, 'media') ) <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script> <script src="/static/js/django-dynamic-formset/jquery.formset.js"></script> <script type="text/javascript"> $('.formset_row-image_set').formset({ addtext: 'add another', deleteText: 'remove', prefix: 'image_set', }); </script> </body> For context, this is an object creation form.

CSRF verification failed on submit after rendering the template via Ajax before
I have a large model formset with initial data, which is injected by ajax through a seperates rendered template. I also pass the csrf token to the template. In the inspector you can also see that the csrf hidden input looks exactly like the other forms on the same page. However, if I want to submit the form, I still get a csrf error. So the complete interface works and also the token is rendered into the template, only I can't submit the form and I don't know why I already tried to render the form without input and inject the inputs via Ajax, but the result was the same. views.py that is called by ajax POST request def render_revolver_table_form(request, product_id, production_step): context = {} context['csrfmiddlewaretoken'] = _get_new_csrf_token template = 'products/product_details/setup_revolver_table.html' SetupRevolverMapFormSet = modelformset_factory(SetupRevolverMap, exclude=( 'product', 'production_step', 'kanal', 'id'), form=SetupRevolverMapForm) setup_revolver_maps = SetupRevolverMap.objects.filter( product=product_id, production_step=production_step).all() context['formset'] = SetupRevolverMapFormSet( queryset=setup_revolver_maps.filter(kanal=1)) return render(request, template, context) injected template <table class="table"> <thead class="thead-dark"> <tr> <!-- Here is content from the formset --> </tr> </thead> <form id="setup_revolver_form_kanal_1" action="" method="POST"> <input type="hidden" name="csrfmiddlewaretoken" value={{csrfmiddlewaretoken}}" /> {{ formset.management_form }} <tbody> <!-- Here is content from the formset --> </tbody> </form> </table> ajax.js csrftoken = $('input[name="csrfmiddlewaretoken"]').val() $.ajax({ url: … -

JavaScript / Django - Displaying Prices on the JQuery date picker calendar
I have implemented a JQuery UI date picker on my "booking" website. I can choose from and to dates, and submit them and make a reservation for the apartment. What I would like to do next is to display prices for each individual day. I also need to be able to do "price-ranges", so one price from date 01-05, another price from 06-12, etc. I'm doing this in Django, as a task I was given, only the calendar is JS, which I don't have much experience with. In the Django backend there is a model where I store the "start_price_date and "end_price_date", aswell as the "price". When I query the backend in JS, this is what I get : 0: "3-10-2019" 1: "999" 2: "4-10-2019" 3: "999" 4: "5-10-2019" 5: "999" 6: "20-10-2019" 7: "666" 8: "21-10-2019" 8: "666" 10: "22-10-2019" 11: "666" So, I get back the dates, and the price for each date. I am having trouble implementing this in the JQuery calendar since I have little to no experience with JS/JQuery. I have tried googling, and went over a few stack overflow posts, tried a few functions but I honestly dont know what I'm doing, this is … -
Django exclude field from all queries
I am running Django on Heroku with zero-downtime feature. This means that during deployment there are two version of code running (old and new) on the same database. That's why we need to avoid any backward incompatible migrations. It there a possibility to exclude a field from Django query on a given model? Let say we have a model (version 1): class Person(models.Model): name = models.CharField() address = models.TextField() In some time in the future we want to move address to the separate table. We know that we should not delete a field for older code to work so Person model may look like (version 2): class Person(models.Model): name = models.CharField() address = models.ForeignKey(Address) _address = models.TextField(db_name='address') This way if old code will query for address it will get it from Person table even if database has been migrated (it will be an old value, but let assume thats not a big issue). How now I can safetly delete _address field? If we will deploy version 3 with _address field deleted then code for version 2 will still try to fetch _address on select, even if it's not used anywhere and will fail with "No such column" exception. Is there … -

How to serialize distinct queryset in django rest framework?
I have a model that handles Italian's VAT rates. There are three types of rate: 'Ordinaria', 'Ridotta', 'Minima' each type of rate can store multiple values according to a date. For example the current rate for ordinary VAT is 22% and has been set on the 1st oct 2013 but rates have changed during time and I need to store changes and to retrieve the three rates according to a specific date. The model to describe rates is called AliquoteIVA. I use a custom manager to retrieve the current rates as of today or by providing a specific date: class AliquoteIVAManager(models.Manager): def current(self, data): return self.filter(data__lte=data) \ .order_by('descrizione', '-data') \ .distinct('descrizione') class AliquoteIVA(models.Model): """ Modello delle aliquote IVA """ data = models.DateField( blank = False, ) descrizione = models.CharField( blank = False, max_length = 1, default = IVA.IVA_ORDINARIA, choices = IVA.IVA_TIPOLOGIA_CHOICES, ) aliquota = models.DecimalField( blank = False, null = False, default = '0', max_digits=19, decimal_places = 2, validators = [MinValueValidator(0.0)], ) objects = AliquoteIVAManager() def __str__(self): str_aliquota = "{0:.2f}".format(self.aliquota).replace('.', ',') return "IVA {descrizione} al {aliquota}% in vigore dal {data}".format( descrizione=self.get_descrizione_display(), aliquota=str_aliquota, data=self.data ) class Meta: ordering = ('-data', 'aliquota',) verbose_name = 'Aliquota IVA' verbose_name_plural = 'Aliquote IVA' I've tested … -

Making field required = False on ModelForm
I've got a model of UserCoupon that a user can create and edit. Upon edit, I only want them to be able to edit the 'code' field on the instance of UserCoupon if there are no orders associated with that code. When there are orders associated with that coupon code, rather than outputting {{form.code}} on the edit coupon form, I'm outputting {{form.instance.code}}. When the user attempts to submit the form, I get an error saying that the field is required. How can I make this field not required or otherwise address this situation so that the user can submit the form when one of the fields defined for the model form shows up in the template as an instance of the field rather than an input box? Models.py class UserCoupon(models.Model): code = models.CharField(max_length=15, unique=True) amount = models.DecimalField(max_digits=10, decimal_places=2, null=True, blank=True) forms.py class EditUserCouponForm (forms.ModelForm): class Meta: model = UserCoupon def __init__(self, *args, **kwargs): self.user = kwargs.pop('user',None) super(EditUserCouponForm, self).__init__(*args, **kwargs) def clean(self): cleaned_data = super(EditUserCouponForm, self).clean() template {% if coupon_order_count > 0 %} {{form.instance.code}} {% else %} {{form.code}} {% endif %} Thanks! -
Django Unittest mockset patching doens't always work

Django - change datafield on database
i am creating a real estate website in Django. I want users to insert/delete images for their properties. It´s all working as expected, except the delete images. In my views.py i have the code: listing = Listing.objects.get(id=1511) if listing: listing.photo_5 = None listing.save(['photo_5']) return True photo_5 is an Imagefield and i want to change the value of that field in database to None. I am saving the image to media folder and save the url in database. photo_5 = models.ImageField(upload_to='photos/%Y/%m/%d/', blank=True) Then when the user clicks in trash can icon, i have an ajax request (working and receives response from view) to delete the image from database. But there is the problem, i am not able to update the url in database or to delete. I already tried with update Listing.objects.all().filter(id = 1511).update(photo_5 = None) It seems that i can not change the value of photo_5. Why is not changing? -

How can I achieve that? so that my output would be: Key one is 19 Key two is 19 Key three is 99
