Django model field automatically incremented, but not according IDs
I am a beginner with Django and I have been searching around this but not reaching a satisfactory solution. Let's say I would like to create a Model to identify a given chair of a table located in a given room of a house, and also its height (of the chair). Consider then records like the following: House Room Table Chair Chair Height (cm) White House Kitchen 1 1 75 White House Kitchen 2 1 55 White House Kitchen 2 2 65 Buckingham Palace Main State Room 1 1 70 Buckingham Palace Main State Room 1 2 70 The compound primary key should include House, Room, Table and Chair. The model I have created does not allow me to increment the integer value of the Chair, once the House, Room and Table are introduced. Is there a way to do that in the models.py file? I do not want to allow the user to introduce any number for the chair field, but to introduce the corresponding following one according to the house, room and table already introduced (There should not be, for example, a 3rd chair without existing the 1st and the 2nd ones). I have been searching the AutoField … -

I am trying to add Facebook login for my Django Project, but I keep getting: Facebook has detected djangosociallogin isn't using a secure connection to transfer information. and Can't Load URL: The domain of this URL isn't included in the app's domains. To be able to load this URL, add all domains and subdomains of your app to the App Domains field in your app settings.

Django Stripe Payment: Invalid card object: must be a dictionary or a non-empty string
When I try to send a payment to stripe I get an error message: "Invalid card object: must be a dictionary or a non-empty string." The payment is for a set amount of 5 Euros. I am using the credit card number 4242 4242 4242 4242 to test the payment. I can see the 'Post' parameters to stripe are all correct apart from the 'stripe_id'.

different extend from different applications
I'm trying to create one template for all apps, but with different base (related to app). i'm using django_hosts: hosts.py: from django_hosts import patterns, host host_patterns = patterns('', host(r'app1', 'app1.urls', name = 'app1'), host(r'(app2|application2)','app2.urls', name = 'app2'), ) tree: templates/document.html app1/templates/app1/base.html app2/templates/app2/base.html templates/document.html: {% extends base %} And the idea is: when I go to http://app1.example.com/document/ i will see templates/document.html extended with app1/templates/app1/base.html, and if I go to http://app2.example.com/document/ or http://application2.example.com/document/ extended with app2/templates/app2/base.html generally it works if I use in app1/views.py: (...) context={ 'base' : 'app1/base.html' } return render(request,'document.html', context) app2/views.py: (...) context={ 'base' : 'app2/base.html' } return render(request,'document.html', context) But I want to remove context 'base' from every views' def . I can't use app1/context_processors.py and app2/context_processors.py, because it would override themselves, because context_processors are global not app local. There's an idea: #main/contexts.py from django.core.urlresolvers import resolve def appname(request): return {'appname': resolve(request.path).app_name} but i don't have urls.py with includes, because i have hosts definition.... -
Letting Users Delete their own accounts in Django
In the Django 2.2 docs , it states the following : "is_active " is a Boolean. Designates whether this user account should be considered active. We recommend that you set this flag to False instead of deleting accounts; that way, if your applications have any foreign keys to users, the foreign keys won’t break. My question is this, If I had a website, and I gave my users the ability to delete their own accounts by following this practice, wouldn't my database be filled with non-active accounts once my website gains a bit of traffic? What would be the best method to letting users ( without staff or super user status ) on your website delete their own accounts properly in Django 2.2 ? Thank you in Advance for any Help -

how do I make toast messages work together

Saving python datetime value to a mySQL timestamp with timezone field
I am baffled. I assign to a Django model field as follows: listing.modify_date = datetime.now() where the field is defined as: listing_modify_date = models.DateTimeField(default=datetime.now, blank=True) Printing out the assigned value... print("modify_date=" + str(listing.modify_date)) I get: modify_date=2020-12-18 21:35:09.178392 But the mySQL table is not updated.

How to render all fields in m2m with a through model?
How could I manage to render something similar to this picture (https://i.imgur.com/3LPGbys.png), where I have my toppings as checkboxes and the amount as a normal input field. E.g. Lets say I have these models (this example is completely fictional) #models.py class Order(models.Model): pizza = models.ForeignKey(Pizza) toppings = models.ManyToManyField(Topping,through='QuantityTopping') class QuantityTopping(models.Model): order = models.ForeignKey(Order) topping = models.ForeignKey(Topping) quantity = models.IntegerField(default=0) class Topping(models.Model): topping = models.CharField(max_length=200) I tried several things, including: Attempt 1. Problem: it just renders the toppings, but not the quantity in any way. Not good, unfortunately. #forms.py class OrderForm(ModelForm): class Meta: model = Order fields = ['pizza', 'toppings'] Attempt 2: I tried to make a separate form only for toppings (my through model). Problem: It managed to all topping as checkboxes (yay!) but only 1 input field. Bummer. #forms.py class ToppingsForm(ModelForm): class Meta: model = QuantityTopping fields = ['topping', 'quantity'] widgets = {'topping':forms.CheckboxSelectMultiple,} Any ideas? thanks in advance! -
Django Exception Value: invalid filter error:

How can i add order detail to paypal smart button checkout

Python, Django: Alternative to a raw-sql-query
Good evening, I would like to ask, if there's a different method to a raw sql query to update items by a certain condition inside my views.py? For example, I know I could do an insert query like this: models.py class Person(models.Model): name = models.CharField() age = models.IntegerField() value = models.IntegerField() views.py def something(request): ... qs = Person(name="John Doe", age=34, value=10) qs.save() ... Is there a similiar method for updating all "Persons" if they fit a certain condition? ... qs = Person("UPDATE Person SET value=5 WHERE age < 30") # or something like this qs.save() ... Thanks for all your help and advice and a great weekend to all of you! -
Custom threaded django comments - django.core.exceptions.AppRegistryNotReady: Apps aren't loaded yet
I am using django 3.1x and I'm following the example here to create a threaded comment app for my project. The article instructs to add the following lines to the __init__.py file so that django can use these hooks to lookup the altered models and forms and to overrides the default set. Here is the content of __init__.py: from models import MPTTComment from forms import MPTTCommentForm def get_model(): return MPTTComment def get_form(): return MPTTCommentForm The error message makes sense, because we appear to be importing objects that have not yet been created ... However, the author of the article states that it works - and none of the comments (granted, they are a year old) seem to be complaining of this issue. Am I missing something, or has the internals (loading sequence of django) changed? How do I fix this? -

django html template not loading from generic view from model
Introduction I am currently working on a small piece of the project to understand more about the Django ORM and to display individual objects. Using Generic views to keep the code clean. (I am somewhat new to Django Framework) Goal The goal of this piece is to show how many users have written an article. For example, I have total of 4 articles. I need to show how many articles written by each user. My console output: User Article Count testuser 2 testuser1 2 testuser2 0 my output on the HTML template: User Article Count testuser 0 testuser1 0 testuser2 0 Problem I am not understanding why my console output is correct, but my HTML template isn't showing the results.

Dajngo Model embed multiple Abstract Models
Suppose I have an Order model for storing customers' orders on my site. There will be two address fields: shipping_address and billing_address. I could write it something like this: class Order(models.Model): order_number = models.CharField() time_created = models.DateTimeField() ... shipping_name = models.CharField() shipping_city = models.CharField() shipping_street = models.CharField() shipping_building = models.CharField() billing_name = models.CharField() billing_city = models.CharField() billing_street = models.CharField() billing_building = models.CharField() ... Then access fields by order.shipping_name and order.billing_name, but that is getting really cumbersome when every address needs to contain 15-20 fields. I tried One-to-One relationships, but code in other places of the application becomes very complicated. If there would be only one address field I could use an Abstract Model to make it a bit cleaner: class Address(models.Model): class Meta: abstract = True name = models.CharField() city = models.CharField() street = models.CharField() building = models.CharField() ... class Order(Address, models.Model): order_number = models.CharField() time_created = models.DateTimeField() But this way I can only have one set of address data and field names from the Address class would clash with fields from Order.

How to use Django channels to push newly created data to client side without reloading and not completely changing the existing normal view code
Hey guys I am quite new to django and django channels. I have a small doubt related to channels. For example, if I have a post model and I created a post, for the user to view the post, they need to either reload the page or we need to redirect them to the list page to view all the posts. What if I want to push the newly created post to the front end or to the client side without having them to reload the page? Can we use channels for that? And if we use channels for that purpose, do we need to rewrite all the codes we wrote in normal views or adding a snippet code like sending a signal when created and running an async function will do the trick? Is it difficult to implement? Thanks -
