Django query using ManytoManyField
Using example code: from django.db import models class Person(models.Model): name = models.CharField(max_length=128) def __str__(self): return self.name class Group(models.Model): name = models.CharField(max_length=128) members = models.ManyToManyField(Person, through='Membership') def __str__(self): return self.name class Membership(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) group = models.ForeignKey(Group, on_delete=models.CASCADE) date_joined = models.DateField() How could I get the name of the last 5 persons and their group's name order by date_joined? Something like: "name1" "group1" "19/02/2019" "name2" "group1" "19/02/2019" "name1" "group2" "19/02/2019" "name3" "group1" "18/02/2019" "name4" "group2" "17/02/2019" I have tried many options but I am not able to do it :S Thanks in advance. -
Django rest framework - Parse key value pair in post()
When user enters in POST API data, they would enter A and B key value pairs. I want to modify the post() to fit my needs. I want to parse the below when user clicks submit or posts API data. Anyway to parse those fields before it's returned on api view(or when user clicks submit)? This is what user is attempting to post using POST API. [ { "A": "1234", "B": "12345", }, ] What I did: class MyModelList(generics.ListCreateAPIView): queryset = MyModel.objects.all() serializer_class = MyModeSerializer permission_classes = (permissions.IsAuthenticated,) def post(self, request, *args, **kwargs): ##parse A values from key value pair so that value == 1234 ##parse B values from key value pair so that value == 12345 return self.create(request, *args, **kwargs) -

Python FileNotFound Djano test media
I'm creating a django project that will accept user content, and during development I'm trying to create a test case that will test that the model uploads normally. I have a file structure like so: Site |----temp | |----django-test |----app |----test_image.jpg |----test_manual.pdf |----tests.py My test case code is such: from django.test import TestCase, override_settings from django.core.files import File import sys import os from .models import Manual # Create your tests here. class ManualModelTests(TestCase): @override_settings(MEDIA_ROOT='/tmp/django_test') def test_normal_manual_upload(self): in_image = open(os.path.join('manuals','test_image.jpg'), 'r+b') in_pdf = open(os.path.join('manuals','test_manual.pdf'), 'r+b') thumbnail = File(in_image) in_manual = File(in_pdf) new_manual = Manual.objects.create( photo=thumbnail, manual=in_manual, make='yoshimura', model='001', year_min=2007, year_max=2010 ) #uploaded_image = open(os.path.join('temp','django_test','images','test_image.jpg'), 'r+b') #uploaded_pdf = open(os.path.join('temp','django_test','manuals','test_manual.pdf'), 'r+b') #self.assertIs(open(), in_image) #self.assertIs(uploaded_img, in_image) #self.assertIs(uploaded_pdf, in_pdf) Here is the model code: class Manual(models.Model): photo = models.ImageField(upload_to="photos") make = models.CharField(max_length=50) model = models.CharField(max_length=100) manual = models.FileField(upload_to="manuals") year_min = models.PositiveIntegerField(default=0) year_max = models.PositiveIntegerField(default=0) For some reason I'm getting a FileNotFound upon opening 'test_image.jpg'). My questions are Why am I getting this error and how do I rectify it? Does my commented section using self.assertIs look correct? -
Django formsets - join two modelformsets to edit fields in BOTH models
I would like to edit fields in two models as part of one form. I know I can do this with inline_formsets - however I want to edit both the parent and child model, but I cannot work out how to do this with inline_formets. My models.py are: class ResultClass(models.Model): result_id = models.ForeignKey(Result,on_delete=models.CASCADE, db_column='result_id') evidence = models.TextField(null=True, blank=True) classified_by = models.ForeignKey(User, on_delete=models.CASCADE, db_column='classified_by', related_name='classified_by', null=True, blank=True) class Meta: db_table = "result_class" unique_together = (('result_id', 'evidence'),) class ReportedResult(models.Model): sample_id = models.ForeignKey(Sample, on_delete=models.CASCADE, db_column='sample_id') result_class_id = models.ForeignKey(ResultClass, on_delete=models.CASCADE, db_column='result_class_id', related_name='result_class_id', null=True, blank=True) reported = models.BooleanField(default=False) date_reported = models.DateTimeField(auto_now=False, null=True, blank=True) class Meta: db_table = "reported_result" unique_together = (('sample_id', 'result_class_id'),) So in the case that I have 4 outstanding Result objects that have not been classified, I would create empty instances of ResultClass and ReportedResult for each Result object. Then I can make model_formsets for each model: forms.py: class ResultClassForm(forms.ModelForm): evidence = forms.CharField( widget=forms.Textarea(attrs={'rows': 3, 'cols': 60}), label='Evidence:', required=False, ) class Meta: model = ResultClass fields = ( 'id', 'evidence', ) class ReportedResultForm(forms.ModelForm): report = forms.ChoiceField(choices=( PRIMARY_CHOICES ) ) class Meta: model = ReportedResult fields = ( 'id', 'report', ) Now in my views I create empty instances of ResultClass and ReportedResult objects … -
Django manytomany choicebox
I would like to implement a choicebox where the user can select the appropriate options and 'transfer' them to a 'selected box' before saving. Django has this for the admin interface , like in this post, but how to implement it in a normal website? Any links to relevent tutorials or an exampled based on te following would be welcome.

3D .obj renderer that can be fit into a canvas in HTML and JS
I'm new at web development, and I'm making a little webapp in Django for my D&D players. There is an "Items" page in the nav that leads to a dynamic item list with contextual buttons. It's looking pretty good! The items follow this structure in the DOM: bootstrap-card boostrap-list-header "Items" bootstrap-ul bootstrap-li-1 bootstrap-row img-of-the-object div-with-info-about-it (name, description, quantity...) contextual-btn bootstrap-li-2 ... bootstrap-li-n Now my question is: How could I replace the "img-of-the-object" with a little 3D renderer to have, for example, little red potions in 3D spinning. Preferably I'd like this engine to be able to render .obj files and overlap a texture on them, as the 3D designer I use (the same one Hypixel uses for their models, I forgot the name) exports that, an .obj and a .png this the skin of the model Thanks you all! -
User model mixin with django
I'm creating a custom User model in Django. I already had a base class for my models, which I now separated using a mixin: from django.db.models import Manager as DjangoModel class ModelMixin(DjangoModel): class Meta: abstract = True objects = Manager() # Not relevant creation_date = DateTimeField(auto_now_add=True, help_text=_('The date in which the database entry was created'), verbose_name=_('Creation date')) last_update = DateTimeField(auto_now=True, help_text=_('The last time that the database entry was updated'), verbose_name=_('Last update')) class Model(ModelMixin): class Meta(ModelMixin.Meta): abstract = True Model is supposed to be a base class of nearly all models I create. In this case, I'm trying to inherit from AbstractBaseUser and ModelMixin: class User(AbstractBaseUser, ModelMixin): objects = UserManager() EMAIL_FIELD = 'email' USERNAME_FIELD = 'email' REQUIRED_FIELDS = [] email = EmailField(unique=True, help_text=_('Email address'), error_messages={ 'unique': _('This email address is already registered.') } ) is_active = BooleanField( default=False, help_text=_('Whether the user is active') ) However, the mixin migrations are not being applied, as I can see be describing the table on the database: CREATE TABLE IF NOT EXISTS "futils_user" ("id" integer NOT NULL PRIMARY KEY AUTOINCREMENT, "password" varchar(128) NOT NULL, "last_login" datetime NULL, "email" varchar(254) NOT NULL UNIQUE, "is_active" bool NOT NULL); Notice that the creation_date and last_update fields are not … -
Saving process data on another table in the database

Problems using both pageview counter and cache in django

How to populate a postgresql database using python

user to user messaging with django-postman
I'm new using django-postman and django and I just downloaded a copy of the django-postman package to use with my app. I added 'postman' to the INSTALLED_APPS settings.py of my project and url(r'^messages/',include('postman.urls',namespace='postman',app_name='postman')), in urls.py. However, I'm not sure where to put the downloaded package and integrated with my project. I think I added the app to my Python path with pip install django-postman==3.6.2, but when I use url(r'^messages/',include('postman.urls',namespace='postman',app_name='postman')) my django program says that there's not an app called 'postman'. How do I include the django-postman app to my project? Also since the app_name='postman' in urls.py is not longer valid for python 3.6 should I just take it out of the statment? -

Update field based on a ManyToManyField in Django model when saving
I have a model Sale defined as follows: from django.db import models class Sale(models.Model): sale_name = models.CharField(max_length = 30) lead_seller = models.ManyToManyField(Employee, related name = "lead") sellers = models.ManyToManyField(Employee, related name = "sellers") lead_share = models.DecimalField(max_digits = 4, decimal_places = 3, null = True, blank = True) sellers_share = models.DecimalField(max_digits = 4, decimal_places = 3, null = True, blank = True) def __str__(self): return self.sale_name And I have created a front-end form where people can register new sales. On saving, I want to compute the "commission" to each seller. E.g. the leads gets 10% and other sellers get 5%. This rate is constant, and thus commission is lower when more sellers are involved in a single sale. I have tried the following: from django.db.models.signals import post_save from django.dispatch import receiver @receiver(post_save, sender=Sale, dispatch_uid="update_shares") def update_shares(sender, instance, **kwargs): no_leads = Sale.lead_seller.through.objects.filter(sale_id = instance.id).count() no_sellers = Sale.sellers.through.objects.filter(sale_id = instance.id).count() instance.lead_share = 0.1/no_leads instance.sellers_share = 0.05/no_sellers However it seems the database query gives 0: the error I get when trying to create a new entry is "Zero Division Error /". Any suggestions on how I can get the number of leads/sellers in a smooth fashion? -

The error: it works almost at all, the JavaScript detects changes on id_codigo properly (I'm trying to check everything with print/console.log). But it gets stuck in the view validar_tipaux where it prints None as codigo's value. What's wrong? -
Reverse relations with django-gm2m using "through" relation
I don't understand how to follow many-to-many relations in the reverse direction with django-gm2m. Here is an example of an models.py: from django.db import models from django.contrib.contenttypes.models import ContentType from django.contrib.contenttypes.fields import GenericForeignKey from gm2m import GM2MField class A(models.Model): pass class B(models.Model): pass class X(models.Model): things = GM2MField() class Y(models.Model): things = GM2MField(through='Yrel') class Yrel(models.Model): y = models.ForeignKey(Y) thing = GenericForeignKey(ct_field='thing_ct', fk_field='thing_fk') thing_ct = models.ForeignKey(ContentType) thing_fk = models.CharField(max_length=255) timestamp = models.DateTimeField(auto_now_add=True) X and Y both have "things" which contains several arbitrary objects. It is Y I have problems with, and X is only for comparison. I have a few objects to test with. a1, a2, b1 = A(), A(), B() a1.save() a2.save() b1.save() etc. With the class X I can do x1, x2 = X(), X() x1.save() x2.save() x1.things.add(a1, b1) x2.things.add(a1) and then get the added things back with x1.things.all() etc. To go in the reverse direction I use x_set as in a1.x_set.count(). So far so good. With "Y" that uses "through" I do y1 = Y() y1.save() Yrel(y=y1, thing=a1).save() Yrel(y=y1, thing=a2).save() to add two "things", and then I can get the list back with y1.things.all() again. But how can I do a reverse lookup from a1 to see where … -
PayPal Orders API V2: Example
i am using PayPal Javasript SDK, and i can not seem to find a good code example of the function actions.order.create(). <script> paypal.Buttons({ createOrder: function(data, actions) { return actions.order.create({ * how to populate this function with more parameters*/ purchase_units: [{ / amount: { value: '{{total}}' } }] }); }, onApprove: function(data, actions) { // Capture the funds from the transaction return actions.order.capture().then(function(details) { // Show a success message to your buyer alert('Transaction completed by ' + details.payer.name.given_name); }); } }).render('#paypal-button-container'); </script> PayPal Docs are not very comprehensive. https://developer.paypal.com/docs/api/orders/v2/. **Any suggestions ? **
