Django + Bootstrap modal form still shows Djangos default errors, not bootstrapped errors?
I am struggling with displaying bootstraps form errors in a popup form modal. When I submit the form, with some missing required fields, I am still getting Django's built in basic form error messages, or even if a field requires a decimal, I enter text, I get an error but it's still django's built in basic validation error. I am using crispy-forms and bootstrap to try to display the errors in a nicer way on the page. This is the way errors are being displayed now.... I have a simple form here... {% load crispy_forms_tags %} <form role="form" method="post" name="employee-add" id="employee-add" action="{% url 'employee_add' company_id %}"> {% csrf_token %} <input type="hidden" id="companyID" name="comp" value="{{ company_id }}"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> <h4 class="modal-title">Add Employee</h4> </div> <div class="modal-body"> <div class="modal-inner defult-inner"> {% for field in employee_form %} <div class="form-group{% if field.errors %} has-error{% endif %}"> {{ field|as_crispy_field }} {% for error in field.errors %} <span class="error-msg">{{ error }}</span>s {% endfor %} </div> {% endfor %} <div class="footer-button employee-footer"> <button class="btn btn-default" data-dismiss="modal">Cancel</button> <button class="btn btn-danger" id="save">Save</button> </div> </div> </div> </form> The modal form is populated with an AJAX GET request. $(function () { // GET request … -
Django: how set default random value for readonly_field in admin view?
In django project, I created a default function called "create_code" to randomly generate a default value for "code" field in models.py file. # models.py class Project(models.Model): name = models.CharField("Project name", max_length=255) code = models.CharField("Code", max_length=10, default=create_code, editable=False) In admin.py file, I set "code" as a readonly_field. #admin.py @admin.register(Project) class ProjectAdmin(admin.ModelAdmin): fields = ('name', 'code') readonly_fields = ('code', ) The problem occours when I create a new Project object in admin page. The default value for "code" appers (eg. ABCD), but when I save the data this value change to another one (eg. EFGH). I think two objects are been created: one when loads the page and other when save the data. How can I read the "code" value from first object to overwrite the last one and save "ABCD" instead of "EFGH"? -
Django ORM bulk update with group by condition
At first have a look at models and query: This is my models class Dish(models.Model): restaurant = models.ForeignKey( restaurant, on_delete=models.CASCADE, related_name="dishes", ) is_active = models.BooleanField(default=True) start = models.DateTimeField(null=True, blank=True) and this is my query def update_dish_status(): today = datetime.today().strftime('%Y-%m-%d') for dish in Dish.objects.all(): if str(dish.start.date()) == str(today): dish.is_active = True dish.save() else: dish.is_active =False dish.save() You may notice that i am updating dish to change is_active and is_active status. Currently it's working the way i dont want that way. I want to when in a restaurant at least one dish's date are same as today's date, then that restaturant's all the dish should be active status False except the dish that is date is same as today date. and if any restaurants dont have such dish that start date matched with today's date, then those restaurants all the dish status should be active, i mean is_active=True For example, i have a restaurants, and in my restaurants 10 dishes. if at least one dish's start date is same as today's date, then that dish will is_active=True and all those dish whose date are not same as today, those dish will be is_active=False But there is another case should be handled like, … -

How to mock serializer in django testing?
So i was testing a rest api method in with we are returning json formatted serializer.data but when we tried to make testcases for this object we couldn't able to mock serializer properly. views.py data = {Something in jason format} serializer = ClassName1(data=data) serializer.is_valid(raise_exception=True) rec_data = {Something in json format} rec_serializer = ClassName2(data=rec_data) rec_serializer.is_valid(raise_exception=True) return Response({'key01':serializer.data, 'key02':rec_serializer.data}) test_views.py @mock.patch('myapp.serializers.ClassName1.data') @mock.patch('myapp.serializers.ClassName2.data') @mock.patch('myapp.serializers.ClassName1.is_valid') @mock.patch('myapp.serializers.ClassName2.is_valid') def test_serializer(TestCase, mock_c2_isvalid, mock_c1_isvalid, mock_c2_data, mock_c1_data): url = reverse('view-name') mock_c2_data.return_value = {dummy json data} mock_c1_data.return_value = {dummy json data} req = RequestFactory().get(url) response = views.Class.as_view()(req) self.assertEquals(response.status_code, 200) above test case is working but we have to patch two times for one serializer if there is any way to mock the serializer object if self and use that to return value for some method. let me know if there is another better way to mock serializer. -

I'm trying to use factory_boy in my tests.

Is there an Visual Studio Code extension for formatting Django template tasg in Javascript?
I have a piece of code here I want to format <script> objectArray = [] {% for object in allObject %} myObject = { title: "{{object.title}}", number: parseFloat("{{object.number}}"), dateCreated : "{{object.dateCreated}}", } objectArray.push(myObject) {%endfor%} </script> After I "Shirt" + "Alt" + "F" to format it with Beautifier extension, it becomes this <script> objectArray = [] { % for object in allObject % } myObject = { title: "{{object.title}}", number: parseFloat("{{object.number}}"), dateCreated: "{{object.dateCreated}}", } objectArray.push(myObject) { % endfor % } </script> Beautifier can format Django template tags in HTML but it becomes strange when it's in Javascript I think a lot of people have the same problem.

Django form.is_valid() is False, but not hitting the else statement?
I am working on something that should be pretty simple, but running into a very odd form issue. @csrf_protect def employee_create(request, company_id): template_name = 'business/employee-create.html' data = dict() company = Company.objects.get(id=company_id) if request.method == 'POST': employee_form = EmployeeForm(request.POST) if employee_form.is_valid(): logger.debug('Valid') emp = employee_form.save(commit=False) emp.company = venue emp.user = request.user emp.save() return redirect('comp_detail', company_id=company_id) else: logger.debug('Error') else: employee_form = EmployeeForm() data['html_form'] = render_to_string( template_name, {'form': employee_form, 'company_id': company.id}, request=request, ) return JsonResponse(data) The GET request is just a popup bootstrap form. But my odd situation is happening in the POST request. I am sending an invalid form that is completely empty(in the form modal I get djangos built in form errors popping up) , but the else statement never gets hit, that is supposed to print Error in my django logger. The form is invalid, but is also not invalid? There has to be something that I am missing here?? Thanks in advance for anyone that takes a glance! -

404 Not Found error on Django deployment with Apache2 Web Server
I rent a VPS and deployed my Django project to it. And placed my project under /var/www/html which is the accessible directory for Apache2. I get 404 Not Found error.

Django all-auth Slack: Redirect URL as https instead of http and Social Network Login Failure

Django: "AttributeError: type object 'AutoField' has no attribute 'rsplit'" after adding "DEFAULT_AUTO_FIELD" to settings.py
I just updated my Django project from 3.1.6 to 3.2.3. After running python manage.py runserver, the server ran with these warnings: core.CoreUser: (models.W042) Auto-created primary key used when not defining a primary key type, by default 'django.db.models.AutoField'. HINT: Configure the DEFAULT_AUTO_FIELD setting or the CoreConfig.default_auto_field attribute to point to a subclass of AutoField, e.g. 'django.db.models.BigAutoField'. Then I remembered that I need to add a DEFAULT_AUTO_FIELD setting to settings.py after updating a project to Django from version < 3.2 to version >= 3.2, so I did: # settings.py DEFAULT_AUTO_FIELD = django.db.models.AutoField Then I tried python manage.py runserver again, but this time I got a different warning: (venv) C:\Users\Chris\my_project>python manage.py runserver Traceback (most recent call last): ... (truncated for brevity) File "C:\Users\Chris\my_project\venv\lib\site-packages\django\utils\module_loading.py", line 13, in import_string module_path, class_name = dotted_path.rsplit('.', 1) AttributeError: type object 'AutoField' has no attribute 'rsplit' I thought that something about my migrations or database was causing the issue, so I deleted db.sqlite3 and all of the app's migrations. Then I ran a fresh python manage.py makemigrations, except that caused the same error: AttributeError: type object 'AutoField' has no attribute 'rsplit' Any ideas why this might be happening? -

When I want to download it, it looks like messy and doesn`t match the html file. Here is my views file. How can I add a css file to the DownloadPDF function. views.py class InvoiceView(DetailView): # vanilla Django DetailView model = Invoice template_name = 'accounting/invoices/invoice_pdf.html' class CustomWeasyTemplateResponse(WeasyTemplateResponse): # customized response class to change the default URL fetcher def get_url_fetcher(self): # disable host and certificate check context = ssl.create_default_context() context.check_hostname = False context.verify_mode = ssl.CERT_NONE return functools.partial(django_url_fetcher, ssl_context=context) class InvoicePrintView(WeasyTemplateResponseMixin, InvoiceView): # output of MyModelView rendered as PDF with hardcoded CSS pdf_stylesheets = [ settings.STATIC_URL + 'core/static/assets/css/pages/invoice.css', ] # show pdf in-line (default: True, show download dialog) pdf_attachment = False # custom response class to configure url-fetcher response_class = CustomWeasyTemplateResponse class InvoiceDownloadView(WeasyTemplateResponseMixin, InvoiceView): # suggested filename (is required for attachment/download!) pdf_filename = 'invoice.pdf' class InvoiceImageView(WeasyTemplateResponseMixin, InvoiceView): # generate a PNG image instead content_type = CONTENT_TYPE_PNG # dynamically generate filename def get_pdf_filename(self): return 'foo-{at}.pdf'.format( at=timezone.now().strftime('%Y%m%d-%H%M'), ) Many Thanks, -

Passing JsonResponse data (from Django views) as a url parameter in Javascript is not working
I am making a website in django that has paypal client side payment integration. My payment works fine but after payment is completed, i send the delivery data to a django views function using fetch API and views function returns me a JsonResponse. I am trying to pass data from that response as a url parameter to another django view which will render a success page about the order with a few details in it. The problem I encounter is as follows: NoReverseMatch at /product-details/payment Reverse for 'order_successful' with keyword arguments '{'DATA': ''}' not found. 1 pattern(s) tried: ['order_successful/(?P[^/]+)$'] here is code for checkout.html which is calling paymentComplete.views <script> function completeOrder(){ var url = "{% url 'paymentComplete' %}" fetch(url, { method: 'POST', headers:{ 'Content-type': 'application/json', 'X-CSRFToken': csrftoken, }, body:JSON.stringify({'prodID': prodId, 'quantity': quantityBought, 'bill': total, 'fName': fName, 'lName': lName, 'apt': apt, 'street': street, 'city': city, 'state': state, 'zipcode': zipcode, 'country': country, 'email': email, 'phone': phone}) }) .then(response => response.json()) .then((data) => { console.log('Success ', data); console.log(typeof data); alert('Transaction Completed'); window.location.href = "{% url 'order_successful' DATA=data %}" }) } </script> following is code for paymentComplete.views def paymentComplete(request): body = json.loads(request.body) prod_ID = int(body['prodID']) prod_Qt_bought = int(body['quantity']) bill_paid = str(body['bill']) #loading product from … -

Problem with decimal field in django v3.2
After upgrading from version 3.1 to version 3.2, I found precision problem in using decimal field. Following example is a small code which could regenerate problem. from django.db import models class Foo(models.Model): amount = models.DecimalField( null=False, decimal_places=18, max_digits=44) # A simple insertion example from api.models import Foo from django.db.models import F from decimal import Decimal f = Foo.objects.create(amount=Decimal('0.5')) f.amount = F('amount') - Decimal('0.4') f.save(update_fields=['amount', ]) f.refresh_from_db() print(f.amount) This code generates 0.099999999999999980 but same code in previous version generate expected result 0.01. By checking mysql query generated for update query, I found that in new version number has sent using a quotation but in previous one there were no quotation. i.e in new version we have something like this UPDATE `api_foo` SET `amount` = (`api_foo`.`amount` - '0.4') WHERE `api_foo`.`id` = 1 but in previous one we had UPDATE `api_foo` SET `amount` = (`api_foo`.`amount` - 0.4) WHERE `api_foo`.`id` = 1. Also I must mention that this happens just in mysql driver not in sqllite. I know this seems like a bug, but I guessed that I am missing something trivial. I am using mysql-8.0.19 and I got the same value in versions 3.2 and 3.2.3 of django.
