connection.queries returns me nothing django
from django.db import connection, reset_queries Prints: [] reset_queries() p = XModel.objects.filter(id=id) \ .values('name') \ .annotate(quantity=Count('p_id'))\ .order_by('-quantity') \ .distinct()[:int(count)] print(connection.queries) While this prints: reset_queries() tc = ZModel.objects\ .filter(id=id, stock__gt=0) \ .aggregate(Sum('price')) print(connection.queries) I was trying to print MySQL queries that Django makes and came across connection.queries, I was wondering why doesn't it prints empty with first, while with second it works fine. Although I am getting the result I expect it to. Probably the query is executed. Also am executing only one at a time. -

Django: prefetch_related has no effect
I'm trying to optimize a DB query using prefetch_related without success. models.py class Order(models.Model): # some fields ... @property def last_operation(self) -> Optional['OrderOperation']: try: return self.orderoperation_set.latest() except OrderOperation.DoesNotExist: return None @property def total(self) -> Optional[Decimal]: last_operation = self.last_operation return last_operation.total if last_operation else None class OrderOperation(TimeStampable, models.Model): order = models.ForeignKey(Order) total = DecimalField(max_digits=9, decimal_places=2) Running a shell, I can see the problem: orders = Order.objects.prefetch_related('orderoperation_set') # There are 1000 orders result = sum([order.total for order in orders]) len(connection.queries) >>> 1003 As we can see, there is one query per order.total, so 1000 queries, that makes the whole request very bad, with performance linear to the number of orders. Trying to understand why this is happening, I found this in the prefetch_related Django doc: Remember that, as always with QuerySets, any subsequent chained methods which imply a different database query will ignore previously cached results, and retrieve data using a fresh database query. So, it seems normal that calling latest() each time run a new query. How would you do to improve performance in this case? (making a few queries instead of N, with N is the number of orders). -
Form sends <textarea> tag along with the body

Django - Modify field value after every query
I am fairly new to Django coming from Laravel background. I would like to modify a field value everytime I query it. For example, every time you query firstname@User you return the Capitalized firstname. In Laravel this is known as Accessors but apparantely Accessors have different meaning in Django. For my case, I have a key-value table called Meta where the value field can be of any type: class Meta(models.Model): key = models.CharField(max_length=30) value = models.TextField() model = models.ForeignKey('Model', on_delete=models.CASCADE) and upon getting the value Meta.objects.get(key='foo'), I would like to return ast.literal_eval(value) to convert the string expression to the correct respective type. I did some research and only found the following: Create a custom Field. Use get_foo_display(self) but this only works for ChoiceField as far as I understood. What is the best choice to apply this function for everytime I query value filtering by the key -

Where to use Java Backend and where Python would win?
This question probably has an answer here. But, all the answers are almost a decade old. I want to know about the current scenario in 2018 where we have hell lotta options like NodeJS, Ruby and PHP. I understand well where to use Node and where should I switch to Java backend (not really sure about Ruby and PHP though) but here, I am more concerned with Java vs Python for backend dev. Which one to go and when? Also, I want a deep intricate answer based on some technical reasons behind and not something like Go with Python if you want to go fast and Java if you want to go far. -

Overwriting a border on an image in Python PIL
I have a gallery application where the users upload photos and my code gives it a border, writes some of the photo attributes on the border and stores it. image2 = Image.open('media/' + str(image.file)) width, height = image2.size; image2 = ImageOps.expand(image2, border=(int(width/25),int(height/20),int(width/25),int(height/10)), fill='rgb(0,0,0)') (Note that here my bottom border is longer than the top because I am writing attributes on the bottom border.) Now I'm building an edit feature for the uploaded images where the user can change the attributes of the uploaded images. But the attributes that are already written on the border have to be overwritten. So here, my approach is to put a black patch on the bottom border and re-write the new attributes without changes the top and side borders and without changing the aspect ratio. All of this has to be done using PIL. Question is how do I put a black box on the bottom border? I tried ImageOps.fit() as mentioned here https://pillow.readthedocs.io/en/3.3.x/reference/ImageOps.html#PIL.ImageOps.fit, but the aspect ratio doesn't seem to be right and I want to overwrite on the black border a black box and not crop the photo. -

Django query returning multiple users instead of one
On my dashboard I'm querying a profile model that has a one to one relationship with user model. But instead of getting one user since there is only one profile per user, I'm getting all users in the database and one profile.
