Django Rest Framewrok: got KeyError when write test for creating (post) nested serializer
I'm try to write test for creating sales data keep getting KeyError: 'content' when running python manage.py test. the test is to ensure user can add/create sales data with its details (nested) with this as reference to create writeable nested serializers models.py # abstract base table for transactions class Base_transaction(models.Model): is_paid_off = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) pass class Meta: abstract = True # sales table to store surface level sales information # consist of sales_id as pk, customer_name, sub_total, discount, user_id, # total, is_paid_off, created_at, updated_at class Sales(Base_transaction): sales_id = models.BigAutoField( primary_key=True, unique=True ) customer_name = models.CharField(max_length=25, blank=True) customer_contact = models.CharField(max_length=13, blank=True) user_id = models.ForeignKey( User, on_delete=models.PROTECT, null=True, db_column='user_id' ) def __str__(self) -> str: return f'{self.sales_id} at {self.created_at} | Lunas={self.is_paid_off}' class Meta: db_table = 'sales' # sales_detail table store the detail of sales per sparepart # consist of sales_detail_id as pk, quantity, individual_price, total_price # sales_id class Sales_detail(models.Model): sales_detail_id = models.BigAutoField( primary_key=True, unique=True ) quantity = models.PositiveSmallIntegerField() is_grosir = models.BooleanField(default=False) sales_id = models.ForeignKey( Sales, on_delete=models.CASCADE, db_column='sales_id' ) sparepart_id = models.ForeignKey( 'Sparepart', on_delete=models.SET_NULL, null=True, db_column='supplier_id' ) def __str__(self) -> str: return f'{self.sales_id} - {self.sparepart_id}' serializers.py class SalesDetailSerializers(serializers.ModelSerializer): sparepart = serializers.ReadOnlyField(source='sparepart_id.name') class Meta: model = Sales_detail fields = ['sales_detail_id', … -
Can't send a post requests
Hi everyone, I'm trying to send a post request through my localhost, my data is a json object, and my following code is: result = df_yahoo.get_history_data() df_yahoo_json = result.to_json() # Convert the Dataframe to JSON headers = { "Content-Type": "application/json", } # Send the POST request with the JSON data response = requests.post('https://localhost:8000/api_yahoo', json=df_yahoo_json, headers=headers) I try to send the request, and then I got the following error: requests.exceptions.ConnectionError: ('Connection aborted.', ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None)) I send the request through the views file in Django. After converting the Dataframe to JSON, I see that the Type of df_yahoo_json is str and not dict of JSON. I would appreciate your help, thank you. -
Django multiple sites using nginx and gunicorn
I am serving multiple websites using nginx and gunicorn and I would like to add another one. Sadly my lack of experience is limiting me, I have some experience with webdesign but always struggle on the server side...|-( (I am using Django because of my Python preference in scientific analysis). My problem: The new site seems to refer to the port used by another. Checking the gunicorn status I see that the site is running although nginx seems to be unable to refer to the correct Django folder. Could someone point me in the right direction? I have been looking around for the last hour or so... (I didn't include any code for now as I am not sure where the error might lie at this point...) -
Filter over jsonfiled with unknown keys in Django ORM
There is a model with JSONfield in Django model: class MyClass(models.Model): is_info = models.BooleanField() info = models.JSONField() The data inside table is like: is_info info false true {'key123':{'a':'1', 'b':'2', 'search_key':'text'},'key456':{'a':'1', 'b':'2', 'search_key':'another_value'}} And I need to filter somehow a query set to receive a set of rows where compound key 'search_key'='text' and not include in result values from 'info' field where 'search_key' has some other values. My keys of 'info' field (key123, key456 and etc.) are always different and I don't know the exact value. Please, help me!!!) I've tried: q = queryset.filter(info__icontains='text') but it return for me all the field info: {'key123':{'a':'1', 'b':'2', 'search_key':'text'},'key456':{'a':'1', 'b':'2', 'search_key':'another_value'}} when I need to receive only: {'key123':{'a':'1', 'b':'2', 'search_key':'text'}} -
How to use objects.filter for (one-to-many) releation
I have 3 tables: Job, Flight, and Image One job can have multiple flights and a flight can have only one job. And a flight can have many images. I get all flights related to the job using the query: flights = Flight.objects.filter(job_id=job_id) and now I want all images in those flights to call a function for all images but I couldn't implement it without a loop: for flight in flights: images = Image.objects.filter(flight=flight) data = process_images(images) I want something like: images = Image.objects.filter(flight=flights) so I call process_images only once, is that possible? -
Not able to retrieve variable in template in Django ajax call

FileNotFoundError at / [Errno 2] No such file or directory while saving an image
I want to create a qr-code generator for hashed values. However, it works pretty strange, because sometimes everything works good, but sometimes it gives me an error: FileNotFoundError at / [Errno 2] No such file or directory. For example, it can save a few qr-codes and then throw that error. Here is the code: def qr_creator(request): for i in range(50): hash_uuid = uuid.uuid4 hash = Hasher.encode(self=Hasher(), password=hash_uuid, salt=Hasher.salt(self=Hasher())) data = f"{hash}" img = make(data) img_name = f"{hash}.png" img.save(str(settings.MEDIA_ROOT) + '/qr_codes/' + img_name) return HttpResponse("Done!") As I understand, the problem lies in img_name as if I change it for example, like this: img_name = f"{hash}.png", everything works as it should be. But I need my qr-codes to be named strictly as hash values. So my question is how can I fix this so I can save my qr-codes with its values? Thanks in advance -

Django Models Reverse Lookup

The Use cases are: Query a school with all its properties including district and province. With: School.objects.all or School.objects.get/filter I can get all schools and the district details but I do not know how to reach the province model. Get all schools in a District With: School.objects.filter(district=x) I can get schools in a district with no problem here. Get all schools in a Province Say I have province ID as 2, how do I get all schools in province 2? Thanks for any help given. -

Django: objects.raw() resulting query but not records
I'm django newbie, I have one fundamental and one technical questions. I'm using Postgres DB. I used psycopg2 connection/cursor for fetching the data, there was some delay while establishing a connection. I read that, ORM takes care of low level activities such as establishing a connection, etc. If I use django, ORM will takes care of connection challenge ? 1.1. Can I expect same (low level activities) with raw() as well? objects.raw(sql) returning Query but not records from the table. I defined Student Model as below class Student(models.Model): firstname = models.CharField(max_length=100) surname = models.CharField(max_length=100) def __str__(self): return self.firstname While creating the view, def studentList(request): #posts = Student.objects.all() --> 1. working as expected (fetching all records firstname) cursor = connection.cursor() sql = "select * from api_student" cursor.execute(sql) posts = cursor.fetchone() --> 2. returning entire record #posts = Student.objects.raw(sql) --> 3. RETURNING SQL QUERY NOT RECORD FROM TABLE ??? print(posts) return render(request, 'output.html', {'posts':posts}) output: <QuerySet [<Student: Anil>]> <RawQuerySet: select * from api_student> --> this is the challenge, did I miss any ('Anil', 'kumar') -
Chart.js automatic background color selector on Django app
I'm working on a Django app with chart.js charts and I'm trying to use a function to automatically change the colors of all the labels. Although when I run the app it only colors one label and makes the other transparent. I tried changing it from labels to data and was getting the same result. It's difficult to share the code as it is pulling data from the app so I'll share what I can. Here is the random color generator code: const labels = ['Category Types']; const backgroundcolor = []; const bordercolor = []; for (i = 0; i < labels.length; i++) { const r = Math.floor(Math.random() * 255); const g = Math.floor(Math.random() * 255); const b = Math.floor(Math.random() * 255); backgroundcolor.push("rgba(" + r + ", " + g + ", " + b + ", 1)"); bordercolor.push("rgba(" + r + ", " + g + ", " + b + ", 1)"); } Here is the chart code: var categoryTypes = JSON.parse(document.getElementById('category_types').textContent) var transactionAmountSum = JSON.parse(document.getElementById('transactionAmountSum').textContent) console.log('categoryTypes', categoryTypes) console.log('transactionAmountSum', transactionAmountSum) $(document).ready(function() { var ctx = document.getElementById('myChart1').getContext('2d'); var myCategory = new Chart(ctx, { type: 'pie', data: { labels: categoryTypes, datasets: [{ label: 'Category Types', data: transactionAmountSum, backgroundColor: [backgroundcolor], borderColor: … -
Download TikTok mp4 on client-side in Django App
I am working on an app and want to download a TikTok video given a URL on the client's machine. I have tried the following to no avail. I would like to do this in as lightweight a manner as possible and with libraries that are popular and maintained, if possible. The issues I have gotten for the attempts are provided therein. Using https://github.com/davidteather/TikTok-Api While this works locally, it does not work when I deploy the application, as I get issues with the threading. I copied over the code from this library and messed around with the threading, but it still did not work fully. I would like to avoid this option as it is not super maintainable.
