Is Django bulk_update slower than update?
I am trying to create and update around 30k data rows at once in the database from Django. This is taking me around 2-5 mins because all these rows have 90+ fields to be updated too, thus to reduce some time in this storage procedure I was planning to use bulk_update and bulk_create in the Django. But after the implementation I realised that this is taking a lot more time than my older process (upsert - update_or_create). Even if I remove the time taken for determining whether to create or insert (which I now realise can be directly done using an arguement in the bulk_create) it is still taking 4 times more time then my query. Based on the name of the function, I was thinking that this should be a better approach for bulk create and update of these many rows and save me sometime, but I don't know why this isn't working like that. Can anyone explain why is this happening and if there is a way to make it faster? The only reason I can come up with till now is that I have too many fields to be updated in a row, i.e., apart from 4-5 … -

JWT token sent as cookie is being deleted when refreshing page (Next.js 14)
I'm using Django REST Framework as backend to handle login, if the user is verified, the service send a cookie with a JWT token. The code below works, I can see the cookie set in my browser. Login view: class Login(APIView): def post(self, request): email = request.data['email'] password = request.data['password'] user = Usuariso.objects.filter(email=email).first() ... key = os.getenv('JWT_KEY') token = jwt.encode(payload, key, algorithm='HS256') res = Response() res.set_cookie( key='jwt', value=token, httponly=True, secure=True, max_age=60*60*24, expires=60*60*24, path='/') res.data = { 'jwt': token } return res The problem occurs when I refresh the page, CSRF and JWT cookies are deleted. The code below fetch login API: app/components/loginForm.js const login = async () => { try { const response = await fetch('http://127.0.0.1:8000/api/user/login', { method: 'POST', headers: { 'Content-Type': 'application/json' }, key: 'Access-Control-Allow-Origin', credentials: 'include', body: JSON.stringify({ email: email, password: password }) }); if (response.ok) { console.log("it works"); } } catch (error) { console.log(error) } }; I have read about JWT, when setting httOnly to true, cookie can not be accessible from javascript, so I think I should not need an third party library to commit this What I have tried: Setting httpOnlny and secure = False Commenting out httpOnly and secure Setting domain as 'localhost' -
NoReverseMatch: Reverse for '...' not found. '...' is not a valid view function or pattern name - for path include name
I have this setup: # Django Project: core/urls.py def redirect_index(request): return redirect(reverse('account'), permanent=False) urlpatterns = [ path('', redirect_index, name='index'), path('account/', include('identity.urls'), name='account'), ] # Django App: identity/urls.py app_name = 'identity' def redirect_index(request): return redirect(reverse('identity:login'), permanent=False) def view_login(request): context = {"test_context": 'This is a test context'} return render(request, "common/base.html", context) urlpatterns = [ path('', redirect_index, name='index'), path('login', view_login, name='login'), ] When I visit http://localhost:8000/, I get this error: NoReverseMatch at / Reverse for 'account' not found. 'account' is not a valid view function or pattern name. What I want is this: If user goes to /, it should redirect to /account/, and from there redirect to /account/login. I know there are 2 redirects, but I'd like to have them separate so that I can set each one separately. But I get the above error. It looks like when there is an include, the name cannot be reversed. Of course, when I use reverse('identity:index') or reverse('identity:login') instead of reverse('account') in core/urls.py, it works. Is there no way I can do it the way I described earlier? -
Angular 14 / NGIX Server | White screen on Firefox and Chrome
Recently we are having issues with the deployment of our Angular App. Its angular 14, running in a ngix server. The issue arises when we do BGD (Blue green deployment, we have two prod environments, we switch between them to have 0 downtime, while one is serving the other is building the new version), our Angular app freezes on a white screen, just loading what is in the index.html (cookies popup, Analytics, etc). Sometimes works on Firefox but not on Chrome, or viceversa. Now it only fails on Firefox and I got some extra insights, looks like when tries to load runtime.js the HTTP call fails with error: NS_ERROR_CORRUPTED_CONTENT. I checked the file exists and it does, and the content is complete, seems correct. The MIME types are correct to for js files. The weirdest thing is that if switch the boolean sourceMap on the angular.json, it works again. Its not that it works being true, it just works again when we switch from true to false or viceversa. I'm running out of ideas or thing to check, and I can't find info related with this. If anyone had a similar issue or haves any insight or different thing to … -

Unable to connect to cloud datastore from local legacy project based on python2.7 and django 1.4
I have a django==1.4 project (python==2.7) that I wanted to run and make some changes. I am unable to connect to cloud datastore from my local codebase. Right now, when I run the project using dev_appserver.py like: dev_appserver.py PROJECT_NAME --enable_console It runs three different servers: API server on localhost:RANDOM_PORT Module default at localhost:8080 Admin server at localhost:8000 Now I visit http://localhost:8000/console and browse interative console and then run some python script like importing User model and fetching if there is anything there or not. And there isn't, why? Because it connects to the local AppIdentityServiceStub. And obviously there isn't any data unless I create some. Now I want to connect this codebase to my cloud datastore and I have tried different implementations that are already on stackoverflow and other platforms. One of them is setting environment variable GOOGLE_APPLICATION_CREDENTIALS to a keyfile.json that service account provides. I have the keyfile.json and I have set it to env variable but still I get connected to local datastore which has no data. Let me know if I am running this project wrong? or is there any other way to connect to cloud datastore from my local? Also, one more thing, when I do … -

how to correctly derive a function book.user_max2() to make xlsx export fast
When exporting .xlsx, the book.user_max2() function increases the load and clogs up the RAM. If you just take book.price from the model, there is no such problem.

Is the __unicode__ method still required for a dynamic Django model? [duplicate]
I found code in our codebase that defines a __unicode__ dunder method for a dynamically created Django model. We are using Python 3.11 and Django 4.2. Is the __unicode__ method still required?

When I egnerate the form, I print the form output and it has 'style "display: none"' emedded in it. from pathlib import Path from django import forms from django_jsonform.forms.fields import JSONFormField from testsite import settings class ConfigurationForm(forms.Form): configuration = JSONFormField(schema=Path(settings.CONFIG_ROOT) / 'config2.schema.json') def configuration(request: Request): if request.method == "POST": form = ConfigurationForm(request.POST) if form.is_valid(): return HttpResponseRedirect("/thanks/") else: with open(Path(settings.CONFIG_ROOT) / 'config.json') as configFile: data = json.load(configFile) form = ConfigurationForm(initial={'configuration': data}) print(f'form data = {form}') return render(request, "admin/preferences/preferences.html", context={"form": form}) The print(f'form data = {form}') statment produces this: form data = <tr> <th><label for="id_configuration">Configuration:</label></th> <td> <div data-django-jsonform-container="true" class="django-jsonform-container"></div> <textarea cols="40" id="id_configuration" name="configuration" rows="10" style="display: none;" data-django-jsonform="{&quot;data&quot;: &quot;{ <!-- sensitive data removed --> }&quot;, &quot;schema&quot;: {}, &quot;fileHandler&quot;: &quot;&quot;, &quot;fileHandlerArgs&quot;: {&quot;field_name&quot;: &quot;configuration&quot;, &quot;model_name&quot;: &quot;&quot;}, &quot;errorMap&quot;: {}, &quot;validateOnSubmit&quot;: false, &quot;readonly&quot;: false}"></textarea> </td> </tr> So what am I doing wrong? -
Django Templates - How can I have correct Root vs App Lookup
How can I have view load the templates from the corresponding app (root vs child)? Here's the full structure: Create django project - universe Created an app - let's call it earth. Created a (container) template for / -> universe/universe/templates/main.html Created a (container) template for /earth -> universe/earth/templates/main.html Created a (content) template for / and /earth at universe/universe/templates/index.html and universe/earth/templates/index.html respectively. In universe/universe/views.py, I have: from django.shortcuts import render def index(request): context = {} return render(request, 'index.html', context) In universe/earth/views.py, I have the same: from django.shortcuts import render def index(request): context = {} return render(request, 'index.html', context) When I run this, I get an error TemplateDoesNotExist at /. Why are templates not found? If I update universe/universe/settings.py TEMPLATES = [ ... 'DIRS': [ BASE_DIR / 'universe/templates' ] ] only the universe templates are picked up. How can I ensure that when I refer to the correct index.html based on the app? -

Limit the dropdown to logged in user for a table field
My tables are: class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.PROTECT, primary_key=True, ) address_line_1 = models.CharField(max_length=200,blank=True) class ProfileCar(models.Model): profile = models.ForeignKey(Profile,on_delete=models.CASCADE) car_model = models.ForeignKey(CarModel,on_delete=models.CASCADE) class AvailableRide(models.Model): profilecar = models.ForeignKey(ProfileCar,on_delete=models.CASCADE) ride_route = models.ForeignKey(Route,on_delete=models.CASCADE) ride_datetime = models.DateTimeField(default=timezone.now) In AvailableRide table, when running it, it shows the complete list of profilecar values, meaning all the users get listed. I want to limit this list to only logged in user. The list needs to be limited to logged in user only, who has onetoone profile record. -
Django: Generate multiple random time
I have Schedule class which has dates, routes and time. I have a problem generating random time. I saw this, (Create random time stamp list in python), but it only generate random time which only has minutes gap each. This is how I did mine, which is just very simple: no_of_route = int(request.POST.get('no_of_route')) time = random.sample(range(1, 24), no_of_route) But this one is just a whole number, I wanted to have results like 9:30, 1:45, and so on. There is no need of min and max time. Is this possible? I'm new to this, so I'm not sure how to do it exactly. Thank you for your help.
