Ajax call doesn't prefix window.location.href if url starts with /
I have been seeing this behavior while trying to translate some backend calls. What happens is that $.ajax gets called with given arguments and the call that is made may or may not have the current location of the window (current url). For instance, At localhost:8000, a .js file calls $.ajax({ type: "GET", async: false, url: /myendpoint/v1/, data: champs, dataType: 'html', success: function (response) { something... } }) The result request translates to: curl "http://myendpoint/v1/" ^ -H "Accept: text/html, */*; q=0.01" ^ -H "Referer: http://localhost:8000/" ^ -H "X-CSRFToken: a-csrf-token" ^ -H "X-Requested-With: XMLHttpRequest" ^ -H "User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.114 Safari/537.36" ^ -H "Content-Type: application/x-www-form-urlencoded; charset=UTF-8" ^ --data-raw "some-data=1" ^ --compressed The preflight and the actual request fail. The preflight naturally gives a network/dns resolution error (failed) net::ERR_NAME_NOT_RESOLVED since "http://myendpoint/v1/" is not a valid hostname. However, if I declare the url without the leading slash, it actually calls the good host with the proper relative URL. Having http://localhost:8000 and a relative url to the server as /myendpoint/v1/ seems correct to me. I tried debugging ajax to see what it does but I didn't get to any conclusion. The RFC specification talks a bit … -
Pytest test suite randomly has errors on GitHub Actions without changes
I have a problem with running my tests for a Python project inside Github Actions. Locally the test suite works like a charm and always succeeds. When it is run on Github Actions it succeeds in 1 out of 3 runs with no changes between the individual runs. It seems as the creation of the Django app during the test doesn't always work as expected. Even though I try to assure it is created inside the pytest fixture. @pytest.fixture def installed_app(settings): app_name = f'test_theme_{str(uuid.uuid4()).replace("-", "_")}' app_path = Path(app_name) call_command("tailwind", "init", app_name) while not app_path.is_dir(): time.sleep(1) settings.INSTALLED_APPS += [app_name] settings.TAILWIND_APP_NAME = app_name app_label = app_name.split(".")[-1] app_path = Path(apps.get_app_config(app_label).path) yield app_name, app_path if app_path.is_dir(): shutil.rmtree(app_path) I am confused what the reason is. I also tried it with Travis CI with the same problem. Any help is highly appreciated. Here is the code of the tests.

Conflito sqlite durante o merge do git [closed]
Estou trabalhando com outra pessoa num projeto Django e ela é dona do repositório principal. Eu tenho um fork desse repositório e quero atualizá-lo com o original. Criei o upstream: git remote add upstream <endereço-do-repositorio.git> Depois: git fetch upstream Até aí correu bem, mas na hora de mergear (git merge upstream/master) apresentou o erro: warning: Cannot merge binary files: db.sqlite3 (HEAD vs. upstream/master) Unlink of file 'db.sqlite3' failed. Should I try again? (y/n) n error: failed to create path 'db.sqlite3': perhaps a D/F conflict? Auto-merging db.sqlite3 CONFLICT (content): Merge conflict in db.sqlite3 Automatic merge failed; fix conflicts and then commit the result. Eu entendi que o problema são as divergências do meu banco com o da outra pessoa, mas como podemos resolver pra conseguir trabalhar em equipe sem causar interferências no projeto principal?

URL resolution in Django with two patterns
There is a need to provide options to task and subtask in Django. where example task is abc_123 ,example subtask is xyz-987 example.com/abc_123/options example.com/abc_123/xyz-987/options My urls.py file urlpatterns = [ url(r'^/(?P<taskId>.+)/options$', views.AvailableOptions.as_view()), url(r'^/(?P<taskId>.+)/(?P<subtaskId>.+)/options$', views.AvailableOptions.as_view()), ] It is working fine when only taskId is sent. When both task and subtaskId is sent. The pattern is taking abc_123/xyz-987 as taskId. I need url to be resolved as abc_123 and xyz-987 as taskId and subtaskId respectively -
How can I make celery more robust with regards to dropped tasks?
Occasionally (read: too often) my celery setup will drop tasks. I'm running the latest celery 4.x on Django 1.11 with a redis backend for the queue and results. I don't know exactly why tasks are being dropped, but what I suspect is that a worker is starting a job, then the worker is killed for some reason (autoscaling action, redeployment, out-of-memory...) and the job is killed in the middle. At this point probably it has exited the redis queue and it won't be picked up again. So my questions are: How can I monitor this kind of thing? I use celerymon, and the task is not reported as failed, and yet I don't see in my database the data that I expected by the task that I suspect failed. How can I make celery retry such tasks without implementing my own "fake queue" with flags in the database? How do I make celery more robust and dependable in general? Thanks for any pointers! -
Django: Annotating price to row, then grouping rows by field, and annotating price sums to groups
My situation: Working on a delivery thingie. I have a Customer, which has one price sheet. The price sheet has pricing zones that are based on postal codes. The customer has DeliveriesOrders, which can have multiple Deliveries (pickups, drop offs) and the price is calculated according the postal code. The way I calculate prices to Delivery rows is: sheet_zones = customer.price_sheet.price_sheet_zones.filter(postal_codes__code=OuterRef("postal_code")) delivery_orders = DeliveryOrder.objects.select_related("customer") \ .prefetch_related( Prefetch( 'deliveries', queryset=Delivery.objects.annotate(price=Subquery(sheet_zones.values("price"))).order_by("-is_pickup"), to_attr="priced_deliveries" ) ) This enables me to have a price annotated for each Delivery row. I however cannot annotate a Prefetch-field, as it results in an error, so .annotate(Sum("priced_deliveries")) doesn't work. I am scratching my head quite hard to get a Sum of all deliveries in a delivery_order. But even more I am scratching my head how to group all deliveries by a field called "reference", and Sum all delivery prices per reference. Pertinent models: class DeliveryOrder(models.Model): customer = models.ForeignKey(Customer, on_delete=models.SET_NULL, null=True, related_name="delivery_orders") class Delivery(models.Model): delivery_order = models.ForeignKey(DeliveryOrder, on_delete=models.SET_NULL, null=True, related_name="deliveries") is_pickup = models.BooleanField(default=True) reference = models.CharField(max_length=64, blank=True, null=True) postal_code = models.IntegerField() Customer related models: class PriceSheet(models.Model): name = models.CharField(max_length=255) class Customer(models.Model): name = models.CharField(max_length=255) price_sheet = models.ForeignKey(PriceSheet, on_delete=models.SET_NULL, blank=True, null=True, related_name="customers") class PriceSheetZoneItem(models.Model): price_sheet = models.ForeignKey(PriceSheet, on_delete=models.SET_NULL, null=True, related_name="price_sheet_zones") zone … -

Image response from DetailView in Django
I'd like to have a DetailView respond with an image file that is saved to the model/object. I have seen this related question but what I am doing is a little different. I have the following model/views/urls - this allows me to display the image in an img tag inside a template when accessing the url localhost/MY-SKU-FIELD. I'd rather not use a template and just respond with the image directly. # models.py from django.db import models class SignModel(models.Model): sku = models.CharField('SKU', max_length=50) sign_image = models.ImageField(upload_to='images/sign') # views.py from django.views.generic import DetailView from signs.models import SignModel class SignDetailView(DetailView): model = SignModel template_name = 'signs/sign_detail.html' slug_url_kwarg = 'sku' slug_field = 'sku' # urls.py from django.urls import path from signs.views import SignDetailView urlpatterns = [ path('<slug:sku>', SignDetailView.as_view(), name='sign-detail'), ] {# 'signs/templates/sign_detail.html #} <img src="{{object.sign_image.url}}" alt=""> Based on the related question/answer, I figure I need to define my own get() method, then fetch the image, and then respond accordingly, but I'm not quite sure how to fetch the image based on the object fetched in DetailView. I've tried fetching with r = requests.get(self.sign_image.url) but that is clearly not working. How do I get the image and respond correctly? -
Bootstrap5 Streched-link doesn't work with a simple card
I have small problem, streched-link doesnt want to work with my card, I tried everything from Bootstrap docs. Tried also removing buttons cause i've read that they doesn't "live well" with streched-link. I use django-bootstrap-v5 (is it good to use this btw.?)

Add data to JWT payload using Django drf-social-auth2 library
I want to add data (such as the token expiration date or user info) to the payload of the JWT generated by this library. I don't have any serializer or view implemented, because the library manages the serializers and the views. I only have to declare the following URL in the urls.py file: urlpatterns = [ ..., path('auth/', include('drf_social_oauth2.urls', namespace='drf')), .../ ] and then I can make POST requests to generate or refresh the JWTs to auth/token/. I've seen solutions (of people that use other libraries) that try to modify the library, and others that implement a serializer and a view, but since the library I'm using is in charge of this task, I don't know how to address this problem. Note: The maintainers of the library indicate that drf-social-auth2 (the library I'm using) relies on python-social-auth and django-oauth-toolkit. The current decoded payload of a JWT is the following { "token": "sXF6EE6jlZRmKhx1mgodOCdUMuSE1I" } -
Saving a ZipFile to FileField in Django
I have the following model in Django: class AksOrder(models.Model): zip_file = models.FileField(upload_to='aks_zips/%M/%S/', blank=True) and in my views I have in essential these functions: def gen_zip(pk, name, vars): zipObj = ZipFile(os.path.join('/tmp/', str(name) + '_' + str(pk) + '.zip'), 'w') zipObj.write(pdf_files[0].path, '/filea.pdf') zipObj.write(pdf_files[1].path, '/fileb.pdf') def aksorder_complete(request, pk): ao = get_object_or_404(AksOrder, id=pk) zipObj = generate_shop_zip(ao.c.pk, ao.dl, ao.vars) ao.zip_file.save('file.zip', zipObj) I did not only try this version, but this one seems the most reasonable and logic one to me. I get a There is no item named 65536 in the archive. When I modify it slightly and close the file at the end of zip-writing in the first function, I get a ValueError: Attempt to use ZIP archive that was already closed message. Both times, the zip-File is generated properly in /tmp/ I could not work arount it. And that's only locally, I need to do it for S3 later... -
Post something if you are already in a group Django
I'm new to Django, and I've just finished an Udemy course based on Python and Django. It's a social media clone project, where, if you are logged in, you can create groups and posts in that group. The problem is that a user can post in any group whether it has joined it or not. I've been asked to code a function that allows a user to post something in a group only if the user is already in that group. It's a daunting task for me. Thank you. -
Get file from server with URL. (DJANGO)
I work in a web app that is used to run a program for students (this program can take some hours to finish) and I used to send the result file via email automatically to the student, but some files are bigger than the maximum size gmail allows to send as attachment. I'm thinking about sending a link via email where the student will click and the file will be downloaded, but I don't know how to create that. The web app works like this: the student uploads some files to the page and clicks run when the student clicks run, those files are copied to a directory in the server, togheter with the program that will run on those files. when the program finishes, it create an output file on that same directory. This is the file that I used to send via email (let's say its path to this file is '/program/<student_name>/output.txt') now, what I wanted to do is send a link via email so when the student clicks on it, it downloads the file in that path. -

HTML form doesn't wan't to send an image
I have a complicated task and for now I don't know reason why things don't work correctly. So I have 2 services - my Django main server and OCR service. OCR service is built with FastAPI and only takes image, processes it and returns response as JSON with data from image. That's how my fastapi file looks like: from fastapi import FastAPI, File, UploadFile, Request import celery_launch from cleaning_folders import cleaning_folder from config import save_img_from_form f_app = FastAPI() def save_img_from_form(image): ts = time.time() * 1000 digit = random.randint(0, 9) file_name = "img_{digit}_{ts}.jpg".format(digit=digit, ts=ts) with open(os.path.join('temp_img', file_name), 'wb') as buffer: shutil.copyfileobj(image.file, buffer) return buffer @f_app.post("/api/ocr") async def send_request(image: UploadFile = File(default='Any', media_type='multipart/form-data')): buffer = save_img_from_form(image) response = celery_launch.ocr_process( selected_town='Templates/Chernomorsk', raw_img_path=buffer.name, selected_billing_type=1 ) json_response = response.get() cleaning_folder('temp_img') return json_response so save_img_from_form() gets an image object from request and saves it to the disk for next processing. Then celery runs and does all OCR process and then returns a dict. So when I use Swagger UI as interactive API testing service, it all works, so in Swagger UI I can load my image through html input and then click the button to run my endpoint. And then I get right JSON as response. … -

Django MultipleObjectsReturned error on form submit
I've got quite the mysterious MultipleObjectsReturned error that just popped up after weeks of not having an issue. I'm hoping is just something simple that I'm missing. I've got an Order model, an OrderLine model, which has an Item foreign key. Each Item has a foreign key to a Product. Here are the dumbed down models: class OrderLine(models.Model): order = models.ForeignKey(Order, related_name="lines", on_delete=models.CASCADE) item = models.ForeignKey(Item, on_delete=models.SET_NULL, blank=True, null=True) class Product(TimeStampedModel): ... class Item(TimeStampedModel): product = models.ForeignKey(Product, related_name='items', on_delete=models.CASCADE) Now, when I use Django admin to edit an OrderLine which has more than one Item in the ModelChoiceField queryset: I get the following error during form clean: get() returned more than one Item -- it returned 2! Upon closer inspection of the logs, it appears the ModelChoiceField is getting passed the correct Item id/pk, but the self.queryset.get(**{key:value}) is somehow returning 2 Items from a single id/pk, even though the Items have different id/pks (49 and 50): Again, this only happens when the OrderLine form's Item field has more than one object in the queryset. If it's only a single Item, it saves just fine. Any ideas why I'm getting this error now? Thanks! The only thing I can think has … -
Vue3 / Vuex changing store state doesn't update computed prop
I work on a ecommerce website build with VueJS 3 and django. Currently facing some issues with the cart functionality. I want to update the amount of items inside the cart without reloading the page, so just updating the cart component. For this I set up a vue app which looks like this: Vue.js <li class="nav-item" id="navbar-app"> <a class="nav-link" href="#">Cart ([[ numItems ]])</a> </li> ...js const store = { state: { numItems: {{ cart.get_cart_length }} }, mutations: { increment(state, quantity) { console.log(quantity) state.numItems += quantity } } } const Navbarapp = { delimiters: ['[[', ']]'], store: store, computed: { numItems() { let cart_items = store.state.numItems return cart_items } } } Vue.createApp(Navbarapp).use(store).mount('#navbar-app') The get_cart_length function just queries the amount of items: cart.py def get_cart_length(self): return sum(int(item['quantity']) for item in self.cart.values()) If a user adds an item to the cart a fetch function is running. Everything works fine if I update the page I get correct results and correct items so this is not the problem. I tried to trigger the store that the computed prop numItems will update like this: (inside the fetch function) ... .then((res) => { this.store.commit('increment', 1) }) ... this throws an error: Cannot read property 'commit' of … -

Django two dependent dropdowns

When creating a document object in django admin, I want the article dropdown (actual language has several articles) only to show up when 'noun' is selected as word type. Currently I got it working to update the choices to '-' if it's not a noun, but the dropdown only updates with init. So I'm looking for a way to update the article dropdown automatically when word type changes. Maybe there is another (better) way of doing it, would be great if there was a solution to make article dropdown completely disappear when 'verb' or 'adjective' is selected as word type. I'm fairly new to django, couldn't find a solution for this since most tutorials assume article and word_type are dependent models, which is not the case for me. -

How can I query a particular percentage of database objects in Django ORM. Am unable to use limiting query set as it requires that the length of objects be specified. I only want get like 48 precent, 30 precent, or 70 Percent of the Django objects in the ORM.. Here's a sample code:: percentage = 60 results =Model.objects.filter()[: percentage]. I simply need a way to query a particular percentage of the objects. Thanks friends. I hope to hear from you all.. Please note that I want to query percentage i.e. 60 percentage, not the exact number of query because I don't know the exact counts Thanks
