Post request causes "django.db.models.query_utils.DeferredAttribute" DRF
I'm quite new at this so patiance please. Now what I was trying to do was, create a function that checks if there are any objects in the database, if there are increase the counter, give that value to a model field and then pass that value to a field on another model. I tried do it as best as I could and when I run a post method, it does post the data, so if I were to check it out on the database, the field which I supposedly update gives me the error django.db.models.query_utils.DeferredAttribute Edit: If i run the code once, as I said it does create the object and the field has that error from above, if I try to make another post request, it crashes and gives the error that the field is supposed to be unique but it isn't. This is my simplified code below, if you need to see more just ask. Thanks in advance. class Order(models.Model): code = models.CharField(max_length=10, unique=True) code_year = models.IntegerField def __str__(self): return str(self.code) def save(self, *args, **kwargs): self.code = Counter.name super(Order, self).save(*args, **kwargs) class Counter(models.Model): def count(self): self.value=0 items = Order.objects.all() for item in items.values('code_year'): self.value+=1 return self.value @property … -

Django JsonResponse not returning expected response of JSON
I’m trying to return some json with this: return JsonResponse({"likes": likes}) The response I’m getting is commented in my client.js code, the response doesn’t contain my json and causes an error when trying to parse the response.

Slugfield not working if field name is different from slug
Good evening, Django is completely new for me and it's my first question here. I'm trying to create a Webapp. I'm using Django, Python and MariaDB. I created a project with two apps and I have a model for each app. In the fist one I used "slug" as field name and everything is working fine. In the second one I wanted to differentiate that field giving a different name (bk_slug) defined as SlugField. I tried to use the same kind of instructions lines and modifying them for the filed name it seems not working. I cannot have the right URL (Class based ListView) and cannot acces to the DetailView.... Thanks in advance for your support. -
Why does React not seem to recognize Heroku's PORT env variable?
I am trying to deploy a frontend react application with a django backend. I am able to get Heroku's PORT environment variable just fine for the Django backend, but no matter what I do or try, process.env.PORT keeps returning undefined. I have tried adding a temporary variable that begins with REACT_APP that just reads the PORT variable in the procfile. Env files won't work because the PORT variable is dynamically allocated. Every resource I have found have said to either try a .env file or exporting the variable, but like I said, that is unrealistic because Heroku dynamically allocates the port. Any ideas? -
Add a skip parameter to Django CursorPagination
I'm looking to implement in Django 3(.1.7) something equivalent to the MongoDB cursor.skip() method. What I'm after is an additional query parameter to provide to my cursor-paginated REST endpoints in order to skip a given amount of items from the result of the query. I can't seem to find any example to obtain this result and I'd like not to reimplement the whole pagination class just to add this small addition. What's the right way to implement this? -
Event Listener for form submit is not working

Unable to create a user at django admin panel
Well, I'm not really sure that this problem is widespread. When I try to add a user from django's admin panel, I get the error about: The module in NAME could not be imported: django.contrib.main.password_validation.UserAttributeSimilarityValidator. Check your AUTH_PASSWORD_VALIDATORS setting From the body of the mistake I learned that: Exception Value: The module in NAME could not be imported: django.contrib.main.password_validation.UserAttributeSimilarityValidator. Check your AUTH_PASSWORD_VALIDATORS setting. Exception Location: C:\Users\Dmitriy\PycharmProjects\FileTime\venv\lib\site-packages\django\contrib\auth\password_validation.py, line 29, in get_password_validators The main problem is that there's nothing about 'get_password_validators' in that line (29) in that file (password_validation.py). The interesting thing is that I can create a user from command line. So, what can I do to solve this problem? -

how to effectively use UUID model field with django
If someone had to build a similar web application like Instagram using Django and expect a large user base as the start up grow, i am wondering if indexing the UUID model field while using postgres as a database would be a good idea after having modified the initial User model provided by django. class User(AbstractUser): id = models.UUIDField(primary_key=True, index=True, default=uuid.uuid4, editable=False) settings.py AUTH_USER_MODEL = "users.User" I have mentioned Instagram as an example to consider Read and Write of the database field in the application. I look forward to hear from anyone familiar with database and django good practices. Thank you -
Load a Django Form into Template using jQuery and stay on same page after submitting?
I am using Django function based views with a single template which contains multiple tabs. Depending on which tab is selected I hide/show certain elements on the page by catching .click() event using jQuery. I populate the visible elements using Ajax requests to certain view functions. I added a new tab to submit data via a form. Currently I have an additional template containing the form. When the tab is clicked, I load the template into an element using jQuery.load(upload.html). The form populates and posts to a Django view through a modelForm. It works alright however I can't seem to figure out how to stay on the same form tab after posting. Any redirect from Django causes the main template to reload to the default starting tab. Also, if the user navigates to main_template/upload.html the form is loaded outside of the main template page. I would like to avoid this. Am I going about this wrong ? main_template.html <div id="myForm"></div> $("#tabButton").click(function(){ $("#myForm").load("upload.html"); }); upload.html <form method="post" enctype="multipart/form-data" action="{% url 'core:upload' %}"> {% csrf_token %} {% bootstrap_form form layout='horizontal' %} {% bootstrap_button "Upload" button_type="submit" %} </form> urls.py urlpatterns = [ url('upload', views.upload, name='upload'), ] views.py def upload(request): if request.method == 'POST': … -
How can I avoid duplicate SQL queries with Django model forms?
I have the following models: from django.db import models class Author(models.Model): name = models.CharField(max_length=30) class Article(models.Models): author = models.ForeignKey(Author, on_delete=models.CASCADE) text = models.TextField() and a generic CreateView from django.views.generic.edit import CreateView urlpatterns += [ path("", CreateView.as_view(model=models.Article, fields="__all__")) ] with the following template (article_form.html) <form action="post"> {% csrf_token %} <table> {{ form }} </table> <input type="submit" value="Submit"> </form> I am using Django Debug Toolbar to list the performed SQL queries for each web request. My question is: Why is the following SQL query for the author list performed twice for each request? And how can I avoid the duplicate query? SELECT "myapp_author"."id", "myapp_author"."name" FROM "myapp_author" Moreover, the debug toolbar says that the first query took only 0.5 ms, whereas the second took 42 ms! Almost 100x longer. How can this be? I am using Django 3.2 with an SQLite database. Thank you! -
