Post.objects.all() not working as i wished
Hey I am currently going through the Django tutorials and I am trying to display all of my Post objects in the python shell using from blog.models import Post Post.objects.all() my model is from django.db import models from django.utils import timezone from django.contrib.auth.models import User # Create your models here. class Post(models.Model): title = models.CharField(max_length=200) contents = models.TextField() date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User,on_delete=models.CASCADE) def __str__(self): return self.title It should display ` [<Post: Blog 1>, <Post: Blog 2>] instead of [<Post: Post object (1)>, <Post: Post object (2)>] It just says "Post object" instead of the title. What is the reason why? I have been following the tutorial exactly and can't understand why it displays it like that. It's hard to organize all of the posts when it says "Post object" for all of them. I am using the latest version of python and django. -

Custom Django Transform with case statement for casting a string to either int or null
I'm trying to create a custom django lookup as_int so that you can easily compare and order the contents of text fields when they contain only a number, and treat them as NULL when they have the wrong format. For example: Comment.objects.filter(body__as_int__gt=5) # Should treat a comment with body="37" as 37 # Should treat a comment with body="abc" as NULL This is what I have so far: class AsIntTransform(Transform): lookup_name = "as_int" output_field = models.IntegerField() def as_sql(self, compiler, connection): case_expr = Case( When( Regex(self.lhs, r"^\d+$"), then=Cast(self.lhs, models.IntegerField()), ), default=Value(None), ) return case_expr.as_sql(compiler, connection) models.CharField.register_lookup(AsIntTransform) models.TextField.register_lookup(AsIntTransform) Trying to filter with the above code is throwing: field_list = name.split(LOOKUP_SEP) ^^^^^^^^^^ AttributeError: 'Col' object has no attribute 'split' It looks like the 'Col' its referring to here is self.lhs in the transform, but I'm not sure what I'm supposed to change to make this work? -
Django errorlist in form Select Valid Choice
The situation is as follows: I am building a form where I fetch data for some fields from an API. I have tried debugging in every possible way, but I cannot understand why the data is not being persisted in the database.

How to debug HTTP 400 Bad Request errors in django?
I have an app with React frontend and Django backend. I'm trying to make a POST request from my react client but I get "Bad Request" error. I checked my request url and it matches with my api url.

Django Inline Formset data not saving
I have created an inline formset which works exactly as I planned on the frontend side- However I can't seem to access any of the data- it seems like the form isn't saving the data? Here in the views.py you can see where it should be saving: def formset_variantingredients_valid(self, formset): variantingredients = formset.save(commit=False) for variantingredient in variantingredients: variantingredient.recipe = self.object variantingredient.save() def formset_images_valid(self, formset): images = formset.save(commit=False) for image in images: image.recipe = self.object image.save() In the admin, in my saved form I can only see the standard fields that have saved and not either of these two inline formsets- Is my issue in the saving of the form itself or am I just not accessing the data correctly? Many Thanks for the help! -
Is the batch processing speed of Python slower than that of Java?
I am working on migrating a function implemented in Java Spring Boot to Python Django. I encountered an issue while migrating a function that retrieves a list of keywords through a select query and updates these keywords using an update query. Specifically, updating 450 rows takes around 0.1 seconds in Java, but it takes 2 seconds in Python. Below are the methods I used to measure the time and the Java and Python code. Measurement method // java long startTime = System.nanoTime(); // Execute the update long endTime = System.nanoTime(); double duration = (endTime - startTime) / 1_000_000_000.0;; String formattedDuration = String.format("%.2f seconds", duration); log.info("processing_time: {}", formattedDuration); // python start_time = time.perf_counter() // Execute the update end_time = time.perf_counter() processing_time = end_time - start_time processing_time_formatted = f"{processing_time:.2f}" logger.info(f"processing_time: {processing_time_formatted} seconds") Logic Java // application.yml spring: datasource: driver-class-name: org.mariadb.jdbc.Driver url: jdbc:mariadb:... username: ... password: ... jpa: hibernate: ddl-auto: none properties: hibernate: show_sql: true use_sql_comments: true format_sql: true dialect : org.hibernate.dialect.MariaDBDialect open-in-view: false sql: init: mode: never // service public void updateUserIntrKwd(String indvNum) { // 2s List<IntrKwdDto> kwdList = intrKwdMapper.selectIntrKwdList(indvNum); // 0.001s DatesAndMaxFrequency datesAndMaxFrequency = getDatesAndMaxFrequency(kwdList); // 0.1s intrKwdMapper.updateUserIntrKwd(kwdList, datesAndMaxFrequency); } // Mapper <update id="updateUserIntrKwd" parameterType="map"> <foreach collection="kwdList" item="item" separator=";"> ...

AJAX Filtering with jQuery and Django Not Updating Product List

However, despite no errors in the console, the product list is not updating as expected.

Payment Gateway Integration with Django
I'm integrating payment gateway APIs in my application (Django). I have written a class PaymentGateway that provides all the methods for all payment related utility. The __init__ initialises the payment gateway client as self.client so that it's available across all methods. But, I need help in making a decision on how to use it. Is it OK if I instantiate and use the payment gateway object across the program, whenever I need it? OR Should I maintain a single instance of it across the whole application? Need help in understanding what could be pros and cons or any other suggestion so that I can make this decision. My current code looks something like below right now: class PaymentGateway: def __init__(self): self.client = PG(api_key="api_key") def create_intent(self, user): return self.client.intents.create(customer_id=user.email) def get_user_id(email): return self.client.users.retrieve(customer_id=email) class MyView(GenericAPIView): def get(self, request): pg_instance = PaymentGateway() intent = pg_instance.create(request.user) return Response({"user_id": get_user_id(request.user), "intent": intent}) # Somewhere in utils.py def get_user_id(user): pg = PaymentGateway() return pg.get_user_id(user.email) -
runser can't serve media if MEDIA_URL is within STATIC_URL, even different settting
In my server,django and nginx is deployed on ECS fargate and connected to loadbalancer, but URL is transferd by Akamai https://www.exmplae.com/company/playground/* -> https://amazonloadbalancer/* So,https://www.exmplae.com/company/playground/ is the url in browser. I have this error django on server (DEBUG=TRUE) runser can't serve media if MEDIA_URL is within STATIC_URL However in this case I have only static setting, no media settings.

Handle Http 302 response on Django view and Javascript async function
For strict security, how can I implement redirect on Django view in response to a JS async call that only updates a div InnerHTML? That is the first preference. I tried JS client-side redirect in multiple ways. It didn't work either. JS keeps rendering home page as InnerHTML in the div. When user's session is ended, server returns 302 Location: /.

Django Auto Assigning Author to the user creating the post
I am having an issue with my Author being auto-assigned, it was previously working but has stopped working since I added some inline formsets- Here is my model: class Recipe(models.Model): title = models.CharField(max_length=100) description = models.TextField() author = models.ForeignKey(User, on_delete=models.CASCADE) serving = models.PositiveIntegerField(default=1) temperature = models.PositiveIntegerField(default=1) prep_time = models.PositiveIntegerField(default=1) cook_time = models.PositiveIntegerField(default=1) ##tags = models.ManyToManyField('Tag') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def get_absolute_url(self): return reverse('recipes-detail', kwargs={"pk": self.pk}) def __str__(self): return self.title Unsure if maybe some of my other code could be overriding this? This is my form: class RecipeForm(forms.ModelForm): class Meta: model = Recipe exclude = ['author', 'created_at', 'updated_at'] def __init__(self, *args, **kwargs): super(RecipeForm, self).__init__(*args, **kwargs) self.helper = FormHelper() self.helper.form_tag = True self.helper.form_class = 'form-horizontal' self.helper.label_class = 'col-md-3 create-label' self.helper.field_class = 'col-md-9' self.helper.layout = Layout( Div( Field('title'), Field('description'), Field('temperature'), Field('serving'), Field('prep_time'), Field('cook_time'), ) ) If I set blank=True, null=True in the model, it allows the form to go through but with no author associated- Even any indication to what could be causing my issue would be hugely helpful!

Better directory structure for Django projects with git perspective

Incorrect Redirection to Login Page from Profile and Logout Links After User Login
Context: I’m working on a Django project where I have implemented user authentication with profile and logout functionality.

How to create a node in neo4j using Django

Invalid block tag on line 1: 'include'. Did you forget to register or load this tag?
During a Django tutorial I've got an issue with the index.html file. I can't handle this exception: Invalid block tag on line 14: 'else'. Did you forget to register or load this tag? I really don't understand why it doesn't recognize "include".
