How to Group and Sum Category with ORM-Query
Please note: Similar questions didn't help me as they have the category-foreignkey in the same class. I have a simple Invoice app with models Invoice, Position, Product and Category. The Product is bound to the Category. My target is to create a queryset that filters e. g. a specific date-range and then group all categories and build their sums Here is a screenshot of the invoice respectively of its positions: The expected result of the grouped query should look like this: Can you help me to create a query that groups and sums the categories within the filtered date-range? The only solution I was able to create was the filter of a specific date-range: queryset = Position.objects.filter(invoice__date_of_purchase__range=['2019-01-01', '2019-12-31']) models.py (which I have simplified): from django.db import models from django.urls import reverse class Category(models.Model): name = models.CharField(max_length=30, unique=True) def __str__(self): return self.name class Product(models.Model): name = models.CharField(max_length=120) category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name='products') def __str__(self): return self.name class Invoice(models.Model): invoice_code = models.CharField(max_length=15) date_of_purchase = models.DateField() customer_name = models.CharField(max_length=100) def __str__(self): return self.invoice_code class Position(models.Model): invoice = models.ForeignKey(Invoice, on_delete=models.CASCADE) product = models.ForeignKey(Product, on_delete=models.CASCADE) quantity = models.DecimalField(decimal_places=2, max_digits=6) price = models.DecimalField(decimal_places=2, max_digits=8) total = models.DecimalField( decimal_places=2, max_digits=8, blank=True, null=True) # is calculated in view … -
Django Join on Composite foreign key
I have a relationship as Follows class Tblrfqvendor(models.Model): """RFQ Master for Vendors This typical represents the same RFQ sent to different people """ ven_rfqid = models.ForeignKey(Tblrfqmaster, db_column='RFQID', on_delete=models.DO_NOTHING, primary_key=True,related_name="venrfq") # Field name made lowercase. lineitem = models.IntegerField(db_column='LineItem') # Field name made lowercase. vendorid = models.CharField(db_column='VendorID', max_length=10) # Field name made lowercase. class Meta: managed = False db_table = 'tblRFQVendor' constraints = [constraints.UniqueConstraint(fields=['ven_rfqid', 'lineitem', 'vendorid'], name='unique_vendor_rfq')] ordering = ['-lastrevdate'] class Tblrfqitem(models.Model): """A Line Item for a particular Master Vendor RFQ """ item_rfqid = models.ForeignKey(Tblrfqvendor, db_column='RFQID', on_delete=models.DO_NOTHING, primary_key=True,related_name='items') # Field name made lowercase. lineitem = models.ForeignKey(Tblrfqvendor,on_delete=models.DO_NOTHING, db_column='LineItem') # Field name made lowercase. itemid = models.CharField(db_column='ItemID', max_length=100, blank=True, null=True) # Field name made lowercase. class Meta: managed = False db_table = 'tblRFQItem' constraints = [constraints.UniqueConstraint(fields=['item_rfqid','lineitem'], name='unique_item')] Now with the related name being items, I write Tblrfqvendorinstance.items.all() However this forms a query where a join is only created on the item_rfqid. Is there a way to help enforce joining on both item_line number and item_rfqid ? A work around I have is to do the following. ven_rfqs = Tblrfqmaster.objects.prefetch_related( Prefetch('venrfq', to_attr='line_items',queryset=Tblrfqvendor.objects.filter(vendorid=vendor_pk).select_related('items') .annotate(itemid = F("items__itemid")) .filter(lineitem=F('items__lineitem')) ) ).filter(venrfq__vendorid=vendor_pk) -
Django Multiple Databases Connections
I have two databases and router defined in my settings.py 'default': { }, 'primary': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': ... }, 'auth': { // similar to primary } DATABASE_ROUTERS = ['pw_inspector.database_router.AuthRouter','pw_inspector.database_router.PrimaryReplicaRouter'] I am running into an issue where Django doesn't recognize the tables/relations within primary database. I tried reordering AuthRouter and PrimaryRouter but then Django won't recognize the User relations from auth database. Any suggestions? I tried making one of them the default but that doesn't solve the issue either. -
Django Model Occurrence Count
I'm fairly new to Django and I'm in need of assistance with my models. class Region(models.Model): region_name = models.CharField(max_length=10) def __str__(self): return self.region_name class Property(models.Model): prop_name = models.CharField(max_length=200) region_name = models.ForeignKey(Region, on_delete=models.CASCADE, verbose_name="Region") prop_code = models.IntegerField(default=0, verbose_name="Property") def __str__(self): return self.prop_name class Sale(models.Model): prop_name = models.ForeignKey(Property, on_delete=models.CASCADE) employee = models.ForeignKey(User, on_delete=models.CASCADE, verbose_name="Person") prop_state = models.CharField(null=True, max_length=5, choices=[('new','New'),('used','Used')]) date = models.DateField('Sale Date') def __str__(self): return '%s : %s %s - %s' % (self.prop_name.prop_name, self.employee, self.date, self.prop_state) Here are my models. Property inherits from Region and Sale inherits from property. What I want to do is count the number of sales in a region and the number of sales on a specific property. However I do not know which would be the best way to approach this. I've tried using a lambda as a model field that uses the count() function but I wasn't able to see much success with that. Please let me know if you have any suggestions. -
Django REST Framework - Query models by field value
I have a Building model for which I have created a Serializer and ModelViewSet. Now I am able to get all Buildings with /api/buildings/ and get a Building object with /api/buildings/3 where 3 is the Building Id. How do I query for a Building object with a particular attribute value? For example, how do I get the Building object with name == "hospital"? Something like /api/buildings?name=hospital does not work. views.py class APIBuildingsViewSet(viewsets.ModelViewSet): queryset = Building.objects.all() serializer_class = BuildingSerializer models.py class Building(models.Model): building_id = models.AutoField('ID', auto_created=True, primary_key=True) name = models.CharField('Name', max_length=125, null=True, blank=False, unique=False) address = models.CharField('Address', max_length=256, null=False, blank=False) user_id = models.ForeignKey('accounts.User', on_delete=models.CASCADE, default=1) def __str__(self): return self.name serializers.py class BuildingSerializer(serializers.ModelSerializer): class Meta: model = Building fields = ('building_id', 'name', 'address', 'user_id') urls.py router = DefaultRouter() router.register(r'buildings', views.APIBuildingsViewSet, base_name='buildings') urlpatterns = [ url(r'^api/', include(router.urls)), ] -
How can I use cPython to profile a Django command I use in docker-compose?
My program is a shell command that I call thru django in docker. docker-compose exec foo ./manage.py bar Where foo is my app and bar is my python script I want to profile. I wanna know everything that cPython can tell me about what's happening in bar, without having to write cPython code inside my code but rather to use the shell command (once SSH to the docker container) like: /usr/bin/python3.7 -m cProfile -s cumtime ./manage.py bar But then I ran into issues of django.core.exceptions.ImproperlyConfigured: The app module <module 'apps.foo' (namespace)> has multiple filesystem locations (['/app/apps/foo', './apps/foo']); you must configure this app with an AppConfig subclass with a 'path' class attribute.

Set Default Stylesheet Class for Images Uploaded using Django-CKEditor
I am using CK-Editor and Django (via django-ckeditor) to create a rich text field and upload images. However, some images are pretty large and I'd normally use bootstrap to make them responsive with the image-fluid class. For Images uploaded with the CKEditor in Django I can set this class manually by going into Image Properties > Advanced > Stylesheet Classes and setting it to image-fluid. Is there any way to set this class as a default? Currently I have tried the following in my settings.py with no luck: CKEDITOR_CONFIGS = { 'default': { 'stylesSet': [ { 'name': 'Image-Fluid', 'element': 'img', 'attributes': {'class': 'img-fluid'}, }, ], }, } Any idea if it is possible to set a deafult class for images uploaded using CKEditor? Thanks. -

Django-Apache Web Server correct setup?
I am currently setting up a VPS web server using Ubuntu 16.04. I have installed all packages, Python3, PIP and Django etc I have set up my root directory such as root -venv -thesantaletter(project) -letter(app) My conf file is set up as following, however when I access this I receive a 403 forbidden error, I am unsure whether the issue lays on the way I have my folder architecture for the project as I have never needed to deploy a django application live before. <VirtualHost *:80> ServerAdmin webmaster@localhost DocumentRoot /var/www/html <Directory ~/santa/thesantaletter/> <Files wsgi.py> Require all granted </Files> </Directory> WSGIDaemonProcess santa python-path=~/santa/ python-home=~/santa/venv WSGIProcessGroup santa WSGIScriptAlias / ~/santa/thesantaletter/wsgi.py </VirtualHost> When I run the development server on port 8000, it runs fine, and with no issues - which leads me to believe that the issue is on the apache side (which isn't my strongest suit).

Django firebase authentication without Django authentication framework
I have created a app authenticating user directly from google firebase, without any user model in the project. I'm using firebase authentication and python Admin sdk. The app is in github. So the idea is to make a custom login and logout views. Also a middleware to process the authentication for each requests. Also the user data can be binded as a python object to improve the usability. At the moment, the middleware logic is there in the home view. With the current logic, every request has to verify the cookies and which is a network request. As per the firebase documents, verification can be done without network requests. Verify session cookies using the Admin SDK verifySessionCookie API. This is a low overhead operation. The public certificates are initially queried and cached until they expire. Session cookie verification can be done with the cached public certificates without any additional network requests. But I couldn't figure out where the cached public certificates and how to use it? I'm using firebase web ui authentication and sending the token to the server and verifying it in the server as per the documents. Is it safe to use the the firebase app config on … -
How to correctly display data stored in an external model without refreshing the page?
I am trying to display a User's name on top of a box where they enter their Employee # in a form, without having to refresh the page. For example, they enter their # and then after they click/tab onto the next field, it renders their name on top, which comes from the database, so the user knows they've entered the correct info. This name is stored in a separate model, so I try to retrieve it using the "id/number". I am not too familiar with AJAX but after reading a few similar questions it seems like an AJAX request would be the most appropriate way to achieve this. I tried to make a function get_employee_name that returns the name of the person based on the way I saw another ajax request worked, but I'm not sure how to implement this so it displays after the # is entered. My page currently loads, but when I check the network using F12, there is never a call to the function/url that searches for the name to display it on the page.
