Pytest-django won't post json data leading to assertion error. Not permission/method related
I'm writing a test for my django online project and I'm stuck in a function that returns 201 if data is valid (it's testing if data is valid when creating a new product for the store.). Django version 4.1.7 Django Rest Framework 3.14.0 pytest 7.2.2 pytest-django 4.5.2 The issue is that no matter what data I input in the function it always returns a 400 error. I'm sure it's not a permission issue because I've got authenticate(is_staff=True), which works in the previous functions. Also, I'm able to post a "Product" both in the Admin panel and in the products url if i'm logged with an account with Staff privileges. Here's the test_products.py code: from store.models import Collection, Product from rest_framework import status import pytest from model_bakery import baker @pytest.fixture def create_product(api_client): def do_create_product(product): return api_client.post('/store/products/', product) return do_create_product @pytest.mark.django_db class TestCreateProduct: def test_if_user_is_anonymous_returns_401(self, create_product): response = create_product({'title': 'a'}) assert response.status_code == status.HTTP_401_UNAUTHORIZED def test_if_user_is_not_admin_returns_403(self, authenticate, create_product): authenticate() response = create_product({'title': 'a'}) assert response.status_code == status.HTTP_403_FORBIDDEN def test_if_data_is_invalid_returns_400(self, authenticate, create_product): authenticate(is_staff=True) response = create_product({'title': ''}) assert response.status_code == status.HTTP_400_BAD_REQUEST assert response.data['title'] is not None def test_if_data_is_valid_returns_201(self, authenticate, create_product): authenticate(is_staff=True) response = create_product({ "title": "abc", "slug": "abc", "inventory": 1, "unit_price": 2, "collection": … -

Hello Ј'ai this error after deploying my application, Key error
Hello Ј'ai this error after deploying my application, I checked everything works locally for users on Django admin. I don't understand this mistake; Could you help me? It looks like it's from the library in django admin and he says he doesn't know the value 1, so maybe it's a problem with this version of django; I would like to point out that I am using version 3.2.12 of django and that I am using a mysql database. enter image description here -
Django - How do I update one field after my ModelForm has changed another?
I have a ModelForm that currently is used to update 2 fields in a Model. Users don't have to update both fields, however, when they do update the "study" field I need to trigger an update to the "user_study_tag" field to 'True' in the model instance. If they simply update the "notes" field (and not the "study" field), I don't want that update happening. forms.py class Run_UpdateForm(forms.ModelForm): def __init__(self, *args, **kwargs): self.request = kwargs.pop("request") site_study_list = kwargs.pop("site_study_list") super(Run_UpdateForm, self).__init__(*args, **kwargs) self.fields["study"].queryset = Study.objects.filter(name__in=site_study_list) class Meta: model = Runs fields = ( "study", "notes", ) models.py class Runs(models.Model): name = models.CharField(max_length=200) guid = models.CharField(max_length=100) site = models.CharField(max_length=30, choices=site_choices, default="-") instrument = models.CharField(max_length=30, default="-") study = models.ForeignKey(Study, on_delete=models.CASCADE, null=True, blank=True) user_study_tag = models.BooleanField(default=False) project = models.CharField(max_length=30, default="-") inventory = models.BooleanField(default=False) inventory_missing = models.BooleanField(default=False) inventory_dismissed = models.BooleanField(default=False) qc_run = models.BooleanField(default=False) analysis_end_date = models.DateTimeField(default=datetime.now, blank=True) archive = models.BooleanField(default=False) notes = models.CharField(max_length=200, default="-", null=True, blank=True) def __str__(self): return f"{self.name}" I thought I could use the clean(self) method in the model, but I don't think that is the right way to handle this issue since I don't know how to compare the form self.study to the model study that is potentially being changed. -
List comprehension vs. for loop
In an effort to avoid Django ModelSerialization performance hits, I am looking at "serializing" a result set on my own. Research says that list comprehension should be the fastest, but my own tests are showing nested for loops being consistently faster. I have raw DB results (100) that need to be converted into a list of OrderedDict based on an ordered list of fields (14). Is my use case too complex for the list comprehension performance advantage, or my sample size too small? Maybe the performance is negligible? Nested for-loop (0.000919342041015625) serialized = [] start = time.time() for raw in results: result = OrderedDict() for index, field in enumerate(fields): result[field] = raw[index] serialized.append(result) end = time.time() print("For loop + for loop " + str(end - start)) Nested list comprehension (0.011911153793334961) serialized = [] start = time.time() serialized = [OrderedDict((field, raw[index]) for index, field in enumerate(fields)) for raw in results] end = time.time() print("List comprehensions + list comprehensions " + str(end - start)) For-loop + list comprehension (0.020151615142822266) serialized = [] start = time.time() for raw in results: result = OrderedDict((field, raw[index]) for index, field in enumerate(fields)) serialized.append(result) end = time.time() print("For loop + list comprehensions " + str(end - start)) -

Tokenauthentication for Angular as frontend and Django as backend
I have an application that uses Django as backend and Angular as frontend. When sending the log-in credentials (username: admin, password: password) via the frontend, it sets a localStorage token and then navigates to tasks.

How to integrate vuejs in a django project?
we need to create a complete website with django and vue as part of a school project, however, we are having trouble integrating vue into our django project. To keep things simple we want to use vue directly in an index.html file located in a django application in templates/app/index.html thanks to the vue cdn. Without vue, the page content is displayed by django, but when we try to use vue with the cdn in this file, nothing is displayed and we get this error in the chrome console: vue.global.js:1661 [Vue warn]: Component is missing template or render function. here is the code: <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>Document</title> </head> <body> <script src="https://unpkg.com/vue@3/dist/vue.global.js"></script> <div id="app">{{ message }}</div> <script> const { createApp } = Vue createApp({ data() { return { message: 'Hello Vue!' } } }).mount('#app') </script> </body> </html> when we run the html file directly in chrome (outside of django) everything works, which means the problem comes from djangom.

How to get a dynamic value from a post and use it to get to a specific function in Django
I'm trying to accomplish this. Though this function: my_site/initpage (that renders mysite/initpage.html) I'm proposing a form where I get three values: start_date, end_date and the specific function that computes and render the specific graphic. This function is where we'll land afterwards (for ex. graphic1, graphic2 and so on). So, in the forms.py I put this: class formGraphicChoice(forms.Form): start_date = forms.DateField( widget=NumberInput(attrs={'class': 'form-control','type':'date'}),required=True, label = "Starting Date" ) end_date = forms.DateField( widget=NumberInput(attrs={'class': 'form-control','type':'date'}),required=True, label = "Ending Date" ) selectedGraph = (('graphic1', 'label_1'), ('graphic2', 'label_2'), ('graphic3', 'label_3'), ) Graphfields = forms.ChoiceField(choices=selectedGraph,label = "Choose the graphic") This works just fine. Then, in the mysite/initpage.html, specifically in the {% block content %} part, I placed the following: <form action="form.cleaned_data['Graphfields']" method="post" class="margin-bottom-0" > {% csrf_token %} <br> {{ form | crispy }} <input type="submit" class="btn btn-primary" value="Show it"> </form> Basically, in action="xx" I would like to put the value of the graphicFields field of the form so to call the chosen function, like this example https://my_site/graphic1. This does not work and I don't know how to handle it. At the moment, I get this: https://my_site/form.cleaned_data['Graphfields'] Thanks a lot for your help! -
django model property depended on request.session value
My models have validation_range field. Very complex. For simplicity I will show example - it may looks stupid but this is for explanation only - so don't look at the model itself, please class Person(models.Model): validity_range=DateTimeRangeField(default=(None,None)) class PersonData(models.Model): person = models.ForeignKey(Person, on_delete=models.RESTRICT) first_name = models.CharField(max_length=255) last_name =models.CharField(max_length=255) validity_range=DateTimeRangeField(default=(None,None)) And now Person can have a two names: E.g. Miss Eva Smith born 1.1.1980 gets married 22.03.2022 and becomes Mrs. Eva Novak. (for simplicity I omit time part of validity_range) So datas look like: Person{id:1,validity_range:(1980-01-01,None)} PersonData{id:1,person_id:1,first_name:'Eva',last_name:'Smith',validity_range:[1980-01-01,2022-03-22)} PersonData{id:2,person_id:1,first_name:'Eva',last_name:'Novak',validity_range:[2022-03-22,None)} I preserve context_date in request.session['context_date']. And I will show Eva's full name dependent of request.session['context_date'] def index(request): person = Person.objects.get(pk=1) context ={ 'person' : person, 'context_date' : request.session.get('context_date') } html_template = loader.get_template('index.html') return HttpResponse(html_template.render(context, request)) html: Context_date is: {{ context_date }} At that date Person no {{ person.id }} was called {{ person.person_data.first_name }} {{ person.person_data.last_name }} Of course this is wrong, because person_data is a set not a object. I thought to make a property in model: class Person(models.Model): validity_range=DateTimeRangeField(default=(None,None)) @property def first_name(self, date): try: person_data =PersonData.objects.get(validation_range__contains=date) #We can assume, that validation_ranges don't overlaps (database constraint) return person_data.first_name except PersonData.DoesNotExist: return None #oups - there's no persondata in that date! But how pass parameter … -
Partitioned tables in psql with django
I partitioned a table in Postgres with Django. All was fine, the insertion went good but when I try to make a query the response is just a field from the original table. So my question is: How is right way to make query in partitioned table in Django?
