Testing form_valid method in Django CreateView
I've been trying to test the form_valid() method in my Django createView and the assertion keeps returning false and i've tried using a normal post request with the client and also using the request factory but the outcomes are same. Below is my view and the approaches i've tried to used in doing the testing. class TextView(CreateView): model = Text form_class = TextForm @transaction.atomic() def form_valid(self, form): self.object = form.save() for i in range(1, form.cleaned_data.get('number_of_pages')+1): Page.objects.create(text=self.object, number=i) return super().form_valid(form) Below are the test i've class TestTextView(TestCase): def setUp(self): self.form_data = { 'name': 'test', 'template': SimpleUploadedFile('test.pdf', b'content') } def test_one(self): form = TextForm(data=self.form_data) self.assertTrue(form.is_valid()) def test_two(self): request = RequestFactory().post('/text') view = TextView() view.setup(request) form = view.form_valid(form=self.form_data) self.assertTrue(form.is_valid()) Both test are supposed to validate the form .

Django doesn't use atomic transactions by default?
I read the django documentation about Database transactions. Then, this section says: Djangoβs default behavior is to run in autocommit mode. Each query is immediately committed to the database, unless a transaction is active. So, as the section says, Django doesn't use atomic transactions by default? So, if Django doesn't use atomic transactions by default, when updating data in Django Admin Panel, there can be Race Condition right? -
How to solve refused to connect problem in Kibana?
I wrote a function for creating charts in Kibana. Firstly, I installed Kibana and Elasticsearch on my local PC. I am sending a request for creating data and charts and taking the embedded iframe code from there. In this scenario everything is okay. I could create charts clearly and my functions are working great. I could show charts on my page. Then I installed my project, kibana and elastic search on a server. And I get this error inside of the iframe tag: 2**...**6 refused to connect. What can be the problem? part of my functions elasticsearch_address= 'http://localhost:9200' self.es = Elasticsearch([elasticsearch_address], use_ssl=False, verify_certs=False, ssl_show_warn=False, send_get_body_as='POST', ) It works fine. I can get and post requests to this address.

Django - How to make a current object "ImageField attribute" as the pre-defined value in a Update_Object view?
I'm creating an update view using django-form for updating one of my objects that have the following fields: class Object(models.Model): name = models.CharField(max_length=40) logo = models.ImageField(upload_to='object_logo/') text_1 = models.TextField() text_2 = models.TextField() So, i have created the following form in forms.py: class ObjectForm(forms.ModelForm): class Meta: model = Object fields = [ 'name', 'logo', 'text_1', 'text_2', ] labels = { 'name': 'Name', 'logo': 'Logo', 'text_1': 'Text 1', 'text_2': 'Text 2', } and defined the following view called update_object: def update_object(request, value): object = get_object_or_404(Object, pk=value) if request.method == "POST": form = ObjectForm(request.POST, request.FILES) if form.is_valid(): object.name = form.cleaned_data['name'] object.logo = form.cleaned_data['logo'] object.text_1 = form.cleaned_data['text_1'] object.text_2 = form.cleaned_data['text_2'] object.save() return HttpResponseRedirect(reverse('myApp:detail_object', args=(value, ))) else: form = ObjectForm( initial={ 'name': object.name, 'logo': object.logo, 'text_1': object.text_1, 'text_2': object.text_2, } ) context = {'object': object, 'form': form} return render(request, 'myApp/update_object.html', context) My problem is: even with an "initial" value stetted up for logo, i have to select an image every time i will update my object (otherwise i receive the update_object page with the message "This field is required").

Revalidate on-demand a Next.js site from Django model's save method
I have a next.js site deployed to Vercel, that fetches data from an API provided by Django. Next.js has this new feature (Incremental Static Regeneration On-Demand) where you can rebuild a specific page without need to rebuild the entire site with an url like this: https://<my-site.com>/api/revalidate?secret=my-token I need the next.js site rebuild some pages when the database changes, so it shows the new data, and i tried to make a request (with requests package) in the save method like this: def save(self, *args, **kwargs): super(MyModel, self).save(*args, **kwargs) r = requests.get("https://<my-site.com>/api/revalidate?secret=<my-token>") It seems to work when it trigger that url from my browser, but it doesn't work when i trigger it from Django. The response of this Response object (r) is a 200 Status Code, as expected, with {"revalidated":true} (r.text), but it doesn't update the site anyways. How can i implement this? -
