502 Error while downloading a huge zip file containing multiple images in it
So,I want the user to be able to click a button and download a zip file containing a bunch of images. A view gets called upon clicking the button, which fetches the images from an SFTP server using pysftp module and creates a zip file and sends a response to the user for download. Now this thing works absolutely fine in most of the cases but in some cases the server throws a 502 proxy error which is because the images are either large in size (This is a hunch) or in number. I assume this is a timeout kinda thing where its taking a lot of time for view to process things. It would be really helpful if anyone could suggest a solution for this. I dont want "502 proxy error" to come in any case. def download_images(request): if request.GET.get('profile_id') and request.GET.get('mattersheet_id'): profile_id = request.GET.get('profile_id') mattersheet_id = request.GET.get('mattersheet_id') cnopts = pysftp.CnOpts() cnopts.hostkeys = None sftp = pysftp.Connection(host=Conf.IMG_SERV_IP, username='blabla',cnopts=cnopts) file_dir = f'''{Conf.DIR_CATALOG_PRODUCT_PATH}/{profile_id}/{mattersheet_id}/products/''' # import pdb; pdb.set_trace() response = HttpResponse(content_type="application/force-download") zip_file = ZipFile(response, 'w') products = products = MatterSheetProducts.objects.filter(matter_sheet_id=mattersheet_id).values('product_code','product_name','product_id','product_category_name').distinct('product_category_name','product_name') import time a = time.time() for product in products: try: if sftp.exists(f"{file_dir}{product.get('product_id')}.jpg"): fh = sftp.open(f"{file_dir}{product.get('product_id')}.jpg",'rb') category_name = product.get('product_category_name') if product.get('product_category_name') else '' … -
How to launch a script based on date/time field
I have set up MariaDB for the backend database for Ptyhon Django project. As it is in the initial POC stage, I will change the database also if you suggest anything. There is a table where the user data will be stored for all the entries the users create. And the table contains a data/time field. I want to trigger email when the date/time field value is equal to current time. Like, if the record1 is having value of tomorrow's 12:31 PM then immediately the email should be triggered to the email ID of the user. The email sending part we can take care but how to trigger the event when the datetime field value is equal to the current date/time. One option is to continuously run a background job to check the date/time value but that is not feasible as 1000s of records will be there. Please suggest, I am a newbie to the Python web projects. -
Django reading json and fetching data to bulk create with optimized approach and minimum resources
Basically i was wondering if i could somehow use a single for loop to achieve a task I am new to python and i am learning about the efficient ways to achieve stuff This is the current scenario json = { items: [ {'uuid': 'some uuid', 'quantity': 2}, {'uuid': 'some uuid', 'quantity': 3}, {'uuid': 'some uuid', 'quantity': 4}] } I am receiving this json and have to make a query to fetch each of these items based on the provided uuid. After fetching these items i have to create their entry in another model which is related to this model. My approach is to separate the uuids and quantity into two separate lists through a for loop for item in json: item_uuids.append(item['uuid']) item_quantities.append(item['quantity']) Fetch item objects q = Q() [q.add(Q(uuid=uuid), Q.OR) for uuid in item_uuids] items = model.objects.filter(q) Then do a list comprehension item_objs = [] [item_objs.append(model(uuid=uuid, quantity=quantity)) for uuid, quantity in zip(items, item_quantities)] Then after all of this I make the final query model.objects.bulk_create(items) Is there any efficient way to achieve this, as it constantly disturbs me i might be following the wrong approach here. Any help would be really appreciated. Thanks in advance -

Django admin custom descending and ascending field
I am using Django Admin to visualize and edit data of my Model. One of the model's field is date and unfortunately is a CharField but with a validator ( dd.mm.yyyy ). I am trying to figure out of a solution to sort those dates in the correct way when the admin press on the sort button that is default from django. In my experience with Java it was all about overwriting the compare function of the class. data_de_montat = models.CharField(help_text="eg: 02.07.2020 or 12.9.2021", max_length=15, validators=[ RegexValidator(r'^[0-9]{1,2}.[0-9]{1,2}.[0-9]{4}$', message='It should be dd.ll.aaaa', code='wrong format' )]) -

DRF nested serializers. Write only primary key, but on read get whole object
I don't need nested create/update operations. I just want to write pk of created object to FK/M2M field and after creating main object get object from this FK/M2M field. Not its primary key. For instance, I got ValueRel and Value models. This is how they are related: class ValueRel(BaseModel): table = models.ForeignKey( Table, on_delete=models.PROTECT, ) object_id = models.CharField(max_length=36) @property def related_object(self): related_model = self.table.get_model() related_object = related_model.objects.filter(pk=self.object_id).first() return related_object class Value(BaseModel): profile = models.ForeignKey( Profile, on_delete=models.SET_NULL, blank=True, null=True, related_name="app_values", ) # I want to write into this field `pk` and get its object value_rel = models.ManyToManyField( ValueRel, blank=True, related_name="values", ) ... After creating ValueRel's instance and writing it to value_rel of Value's instance I want to get ValueRel's instance like object. Actual result (JSON response from API) "value_rel": [ "6a740343-0d37-4e6b-ba56-0c60ac51477f" ] Expecting this: "value_rel": [ { "pk": "6a740343-0d37-4e6b-ba56-0c60ac51477f" "table": "Speciality", "object_id": "02548144-a27d-4c17-a90b-334ccf9e1892", "related_object": "Information system" } ] Is there a way not to adding another field just for expected object representation and get it from value_rel? -
{% translate s %} passed in {% include ... with s=s %} not in .po file
I have a basic feed I am trying to render in my Django project. I have created a feed.html file as a base template for slight variations of the same type of feed. Among those variations, is the header of the feed. Importantly, I want that header to be translated into multiple languages. I have implemented this "variation" idea using {% include "feed.html" with variation=variation %}. However, I am having problems translating those variations. I am trying the following in feed.html: {% translate header %} Then in one of the templates where I want a variation of feed.html I have: {% include "feed.html" with header="Header" %} The problem is, the string "Header" does not make it into any of my .po files and therefore remains untranslatable. What am I doing wrong? Should I use different syntax? -

Heroku Redirect non-www to www on Django website
I currently have a website domain with Bluehost. Bluehost cannot redirect https://example.com to https://www.example.com using 301 redirects since I am not hosting with them. Now in my DNS settings, I have a CNAME (Alias) record that points @ to <string1>.herokudns.com and I have another CNAME (Alias) that points www to <string2>.herokudns.com. I have contacted Bluehost and they said one solution would be to point both www and @ to <string1>.herokudns.com but that does not seem to be a redirection to me. How can I manage to redirect the naked domain to www within Heroku on Python? I cannot test them a lot since Bluehost TTL is 4 hours and I cannot manage to change my configurations fast. Appreciate any help in advance!
