Django unit test will not update BooleanField
I have a situation where I want to have published functionality for articles, and I have it. The problem is that I can't get my unit test to work properly, trying to post True to the published field. Here's what my tests look like. class ArticleDetailViewTest(TestCase): def setUp(self): email = 'testuser@gmail.com' first_name = 'test' last_name = 'user' password = 'test15146' user = User.objects.create_user(email, first_name, last_name, password) self.client = Client() self.client.login(username='testuser@gmail.com', password='test15146') def test_can_publish_article_from_POST(self): other_article_two = Article.objects.create(name='Test Name One', author=User.objects.get(email='testuser@gmail.com')) correct_article_two = Article.objects.create(name='Test Name Two', author=User.objects.get(email='testuser@gmail.com')) response = self.client.post(reverse('publish_article', kwargs={'pk' : correct_article_two.pk})) self.assertEqual(response.status_code, 302) self.assertRedirects(response, f'/articles/{correct_article_two.pk}/') self.assertEqual(correct_article_two.published, True) Here's what my publish article view looks like. def publish_article(request, pk): article = get_object_or_404(models.Article, pk=pk) if request.method == "POST": article.published = True article.save(update_fields=['published']) return redirect('article_detail_view', pk=article.pk) else: raise Http404 Here are my urls. from django.urls import path from . import views urlpatterns = [ path('', views.HomePageView.as_view(), name='home'), path('new/', views.ArticleCreateView.as_view(), name='article_new'), path('<int:pk>/', views.ArticleDetailView.as_view(), name='article_detail_view'), path('<int:pk>/publish/', views.publish_article, name='publish_article'), path('<int:pk>/unpublish/', views.unpublish_article, name='unpublish_article'),] Here are my models. from django.conf import settings from django.db import models from django.urls import reverse from django import forms class Article(models.Model): name = models.CharField(max_length=255, blank=False) author = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, ) published = models.BooleanField(default=False) def __str__(self): return self.name def get_absolute_url(self): return reverse('article_detail_view', args=[str(self.id)]) … -
django query with prefetch_related
I am struggling to get at the data I need from a prefetch-related query. I have a table of events (the calendar table), a table of members and an attendee table which links the two. My models look like: class Member(models.Model): firstname = models.CharField(max_length=40) lastname = models.CharField(max_length=50) email = models.EmailField(blank=True, verbose_name ='e-mail') phone = models.CharField(max_length=40) membershipnum = models.CharField(max_length=40) class Attendee(models.Model): memberid = models.ForeignKey(Member, on_delete=models.SET(0), related_name="attendingmembers") calendarid = models.ForeignKey(Calendar, on_delete=models.SET(0)) attended = models.BooleanField(default=0) paid = models.BooleanField(default=0) class Meta: db_table = 'attendee' For a particular event I want a list of attending members with the attended and paid fields from the attendee table. In my view I have attendees = Member.objects.filter(attendingmembers__calendarid_id=id).prefetch_related('attendingmembers') I am getting the right members, but I don't know if this is the best way to do it? And I can't figure out how to get at the attendee fields. If I do for thisone in attendees: print(thisone) print(thisone.attendingmembers) I get the expected return from the first print, but the second just gives me myapp.Attendee.None Any advice much appreciated. -
select related in Django
I am trying to accomplish something very similar to: How to join 3 tables in query with Django Essentially, I have 3 tables. In the Django REST we are showing table 3. As you see below (models.py), table 3 has company_name which is a foreign key of table 2 and table 2 is a foreign key of table 1. Both table 2 and 3 are linked by the table 1 ID. Table 1 contains the actual text, which we want to display in the API output, not the ID number. Table 1: Manufacturer of Car -- Table 2: What the Car is -- Table 3: list of all cars Models.py Table 1: class ManufacturerName(models.Model): name_id = models.AutoField(primary_key=True) company_name = models.CharField(unique=True, max_length=50) class Meta: managed = False db_table = 'manufacturer_name' Table 2: class CarBuild(models.Model): car_id = models.AutoField(primary_key=True) car_icon = models.CharField(max_length=150, blank=True, null=True) company_name = models.ForeignKey('ManufacturerName', models.DO_NOTHING) class Meta: managed = False db_table = 'car_build' Table 3: class CarList(models.Model): list_id = models.AutoField(primary_key=True) company_name = models.ForeignKey('CarBuild', models.DO_NOTHING, db_column='news_source') title = models.CharField(unique=True, max_length=100) description = models.TextField() class Meta: managed = False db_table = 'cars' Within my views: This is what I am trying, based on the foreign key relationships: queryset = CarList.objects.all().select_related('company_name__company_name') I get … -

Django - Using {% for field in form %} on checkboxes, causes field to generate all alternatives
In my template I would like to display all my checkboxes, but having custom tags between each alternative. But the {{ field }} tag (to my surprise) does not generate one alternative at a time but rather spits out everything at once, since all alternatives belong to the same "field". How can I iterate through each alternative instead? See code example below. What I have: template.html <div id="checkRadios"> <div class="col-sm-6 col-lg-3"> {% for field in form %} <div class="checkbox"> {{ field }} <span class="checkmark"></span> </div> {% endfor %} </div> </div> What I get: <div id="checkRadios"> <div class="col-sm-6 col-lg-3"> <div class="checkbox"> <label for="id_0"><input type="checkbox" name="name_0" value="26" id="id_0" /> one</label> <label for="id_1"><input type="checkbox" name="name_1" value="27" id="id_1" /> two</label> <span class="checkmark"></span> </div> </div> What I want: <div id="checkRadios"> <div class="col-sm-6 col-lg-3"> <div class="checkbox"> <label for="id_0"><input type="checkbox" name="name_0" value="26" id="id_0" /> one</label> <span class="checkmark"></span> </div> <div class="checkbox"> <label for="id_1"><input type="checkbox" name="name_1" value="27" id="id_1" /> two</label> <span class="checkmark"></span> </div> </div> -
Django M2M with a large table
I have a typical M2M scenario where promotion activities are related to our retailers. However we have a large number of retailers (over 10k) and therefore I can't use the normal multiple select widget. What I would aim to do is have an 'activity' instance page with a 'retailer' sub-page which would have a table listing all those retailers currently related to the activity. In addition there would be a 'delete' checkbox next to each retailer so they could be removed from the list if necessary. (Naturally, I would also have another search/results page where users could select which retailers they want to add to the list, but I'm sure I can sort that out myself). Could someone point me in the right direction regarding modelforms and formset factories as I'm not sure where to go from here. It would seem obvious to directly manipulate the app_activity_associated_retailers table but I don't think I can do this with the existing functions. Is there was a pattern for doing this. class Activity(models.Model): budget = models.ForeignKey('Budget') activity_type = models.ForeignKey('ActivityType') amount = models.DecimalField(max_digits=8, decimal_places=2) associated_retailers = models.ManyToManyField('Retailer', related_name='associated_retailers') class Retailer(models.Model): name = models.CharField(max_length=50) address01 = models.CharField(max_length=50) address02 = models.CharField(max_length=50, blank=True) postcode = models.CharField(max_length=5) city … -

Django display different models/tabells
I get stuck. I try to display each time a other table in django with the same def in my view.py code. First problem is I can't transfer the string which I enter in the url to a model.

filling a Django form from a separate requests.post python script
while reading about the Requests library, it occurred to me that I could try to fill a form by using it. So, since I have Django and the server, I first checked that I got the URL well and got a 200 answer code. like this: import requests r = requests.get('127.0.0.1/myform') print(r.status_code) and yes, it was a 200 so the next step was going to be entering a value in the textfield, actually the form, for this example is just one field. I tried this: r = requests.post('127.0.0.1/myform', data ={'name' : 'Mexico'´} and nothing was entered. Here I have like 3 intriguing questions: When I inspect the element, because the form was created using the ModelForm of Django, I could not actually give the field a name, (which would have been name) and 2. Django instead fills me the name with the csrf token value and 3. actually, I don't see how the requests.post presses the submit button. What would be what is missing here in order to succeed posting the value through the form? thank you -

Changing field in Django Form, overriding clean()
I have a date, passed as 2019-01-01T00:02. My objective is to replace the T with a whitespace, 2019-01-01 00:02. Using Form, i validate that field and some others.' klientForm = KlientForm(json.loads(request.body.decode())) bokningForm = BokningForm(json.loads(request.body.decode())) if klientForm.is_valid() and bokningForm.is_valid(): #Save model, etc. I'm using DateTimeField, and it will not accept the date unless I change it like above. I implemented my own clean() method, def clean(self): cleaned_data = super(BokningForm, self).clean() pumpStart = self.data['pumpStart'] pumpStart = pumpStart.replace("T", " ") cleaned_data['pumpStart'] = datetime.strptime(pumpStart, "%Y-%m-%d %H:%M") return cleaned_data This successfully converts it to a datetime object, I checked using print(cleaned_data) My issue is that the data is returned to late, as (I think) bokningForm.is_valid() has already failed, resulting in the model not being saved. I tried using clean_pumpStart(self): as in Django Forms but the function was not called when bokningForm.is_valid() failed, resulting in the same issue as above. Any help appreciated! -

The traceback of the error is: Traceback (most recent call last): File "manage.py", line 15, in <module> execute_from_command_line(sys.argv) File "/usr/local/lib/python3.5/dist-packages/django/core/management/__init__.py", line 371, in execute_from_command_line utility.execute() File "/usr/local/lib/python3.5/dist-packages/django/core/management/__init__.py", line 365, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/usr/local/lib/python3.5/dist-packages/django/core/management/base.py", line 288, in run_from_argv self.execute(*args, **cmd_options) File "/usr/local/lib/python3.5/dist-packages/django/core/management/base.py", line 335, in execute output = self.handle(*args, **options) File "/usr/local/lib/python3.5/dist-packages/django_dramatiq/management/commands/rundramatiq.py", line 83, in handle os.execvp(executable_path, process_args) File "/usr/lib/python3.5/os.py", line 615, in execvp _execvpe(file, args) File "/usr/lib/python3.5/os.py", line 660, in _execvpe raise last_exc.with_traceback(tb) File "/usr/lib/python3.5/os.py", line 650, in _execvpe exec_func(fullname, *argrest) FileNotFoundError: [Errno 2] No such file or directory I've made skeleton Django-project with single Dramatiq-task to reproduce the problem.

Is there a way I can initialize the value of an attribute of a django REST serializer based on the values of another field in the same serializer?
class MySerializer(serializers.Serializer): owner=serializer.ReadOnlyField(source='auth.username') ownerUrl = ..... Say I have a serializer like so, with the create and update methods (not shown here), now what I want is the ownerUrl to take a value when a serializer is made, according to the owner value of the same serializer, how do I do this? for example is we make a serializer like so serializer=MySerializer(MyModel.objects.get(pk=10)) then serializer.data.get('ownerUrl') has a value which is based on the value of the owner, may be something like <value of owner>+"/".
