Django 2 Test: Created object cannot be gotten for tests
I've read about building programs starting with tests, so I thought I'd give it a shot. I've made my initial project and app and a model, but when I try to run a test, I get a "Does not exist" error. I've run the migrations, is there more I have to do before I can run a test? Here's my code: models.py from django.db import models class Name(models.Model): first_name = models.CharField( "First Name", max_length=100, ) middle_name = models.CharField( "Middle Name or Initial", max_length=100, default='', ) last_name = models.CharField( "Last Name", max_length=200, ) def __str__(self): return f'{self.last_name}, {self.first_name}' tests.py from django.test import TestCase from contacts.models import Name class TestNameModel(TestCase): @classmethod def setupTestData(cls): Name.objects.create(first_name='Banny', last_name='Banvil') def test_name_exists(self): name = Name.objects.get(id=1) print (name) And the error that I get: Creating test database for alias 'default'...

Django migrations run_before and reset give same error
I have a project with a custom user model. Because of an unrelated screw up, I had to reset migrations. Since I already had set the custom user once, I didn't think about migrating it separately first again, so of course I got django.db.migrations.exceptions.InconsistentMigrationHistory: Migration admin.0001_initial is applied before its dependency account.0001_initial on database 'default'. Reading this error literally, it seems like I ought to be able to adjust the sequence and be ok, rather than the more challenging steps laid out for when you try to change to a custom user mid project https://docs.djangoproject.com/en/2.0/topics/auth/customizing/#changing-to-a-custom-user-model-mid-project. See https://docs.djangoproject.com/en/1.11/howto/writing-migrations/#controlling-the-order-of-migrations However, when I did run_before, I STILL got the same error. Here is that code: class Migration(migrations.Migration): initial = True run_before = [ ('admin', '0001_initial'), ] So I tried a reset: python manage.py migrate admin zero And I STILL get the same error! So then I tried: dependencies = [ ('auth', '0007_alter_validators_add_error_messages'), ('admin', '0001_initial'), ] And, you guessed it, same error! What am I doing wrong, and/or what are my options here? Thanks. -

Django REST Framework and Vue.js throwing IntegrityError on post

Turbodbc returns ODBC error state 60 when run from apache2/mod_wsgi
I have a Django website that uses TURBODBC to execute some direct SQL calls on a legacy database. This works perfectly when using the built in django test server, but when I run it with Apache2 I get the error message: “ODBC error state: 60”.

Delete file from specific model field when uploading a new version when Model has several file.fields without deleting everything Django
my problem is regarding orphaned files and the fact that my model uses several file fields. I have a model for a user, which has a profile image field and a cv field. The user is able to update these fields which works fine but the files remain. Now I've looked at various solutions online, created my own etc but its not working quite properly. The problem with my solutions (see below) is that it deletes all media files associated with that instance at that time even though I've only changed one value. Additionally, each of the fields have their directory path. Its fine when I change both fields since both change and the previous files are deleted but often people only change one value so how do I fix this? I don't want to use django-cleanup for a variety of reasons. models.py def teacher_avatar_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> return 'teachers/avatar/{0}/{1}'.format(instance.user.email.replace(" ", "_").lower(), filename) def teacher_cv_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> return 'teachers/cv/{0}/{1}'.format(instance.user.email.replace(" ", "_").lower(), filename) #Teacher class ProfileTeacher(models.Model): created = models.DateTimeField(auto_now=False, auto_now_add=True, blank = False, null = False, verbose_name = 'Creation Date') user = models.OneToOneField(app_settings.USER_MODEL,blank=True, null=False) first_name = models.CharField(max_length = 400, null=True, … -

Django migration to multiple databases
I am using two databases in my django project. To handle that I have a router files: class SecondDB: """ A router to control all database operations on models in the auth application.

I can migrate specific app ./manage.py migrate app_in_second_db 0001_initial --database second_db but wonder if there is some error in my router file and how to prevent accidental moving all the models to the second_db database.

Change the widget for django admin's foreign key inline to a pop-up like the many-to-many's
I have a few models in my django project: CoursePacks, Courses and Chapters. Courses have a many-to-many relationship to the CoursePacks, which in the admin, after some inline editing, displays this widget: (This is a COURSE-COURSEPACK relationship) Which allows me to select, edit and create another course which will be automatically added to the course pack. The chapter ("capítulo") and the course models, however, are connected through a foreign key relationship, and the widget displayed on the admin is the following: (This is A CHAPTER-COURSE relationship) Which I have edited so that less fields are shown, because if I didn't all the fields and the entire textarea content would be displayed. When I click on the add or edit button to the side of the course instance on the course pack admin window, a window pops up which allows me to edit or create another course. I would like to be able to have a similar mechanism but for creating chapters through the course admin window. Will I have to edit the admin's markup or is there a widget editing functionality that does what I need? If not, where could I begin to do so? -
Django update model without UpdateView
I have a scenario where in my users profile they have an associated organisation. I need to be able to allow the users to select and set this organisation (user_organization), however I would like to do it without allowing them to just see a list of all the organisations within the application. My work around for this was to issue each organisation with a unique code (org_code) and allow users to enter that code into a form and have the related organisation applied to their profile. I can easily understand the suedocode logic behind this, however I am unsure how to implement it within my views and forms. If anyone can advise me the best way to do this or point me in the correct direction to learn how? It would be appreciated. See my models below for clarification on how things fit together. Profile: class Profile(models.Model): Super_Admin = "Super_Admin" Admin = "Admin" Manager = "Manager" Developer = "Developer" ROLE_CHOICES = ( (Super_Admin, 'Super_Admin'), (Admin, 'Admin'), (Manager, 'Manager'), (Developer, 'Developer'), ) user = models.OneToOneField(User, on_delete=models.CASCADE) user_group = models.OneToOneField(Group, on_delete=models.CASCADE, blank=True, null=True) user_organization = models.OneToOneField(Organization, on_delete=models.CASCADE, blank=True, null=True) role = models.CharField(choices=ROLE_CHOICES, default="Developer", max_length=12) activation_key = models.CharField(max_length=120, blank=True, null=True) activated = models.BooleanField(default=False) … -

django/js submiting form and getting response without refreshing page
I was making this simple bmr calculator app the problem is when i submit i dont want to go to any other page i want to show the results in the same page instead of having to go to another page. views.py def bmrvalue(age ,height ,weight , gender ): if gender == 'm': BMR = (10 * weight ) + (6.25 * height ) - (5 * age ) + 5 else: BMR = (10 * weight ) + (6.25 * height ) - (5 * age ) - 161 return BMR def MyBmr(request): if request.method == "POST": form = BmrForm(request.POST) if form.is_valid(): age = form.cleaned_data['age'] height = form.cleaned_data['height'] weight = form.cleaned_data['weight'] gender = form.cleaned_data['gender'] mybmr = bmrvalue(age,height,weight,gender) return render (request , 'resultes.html', {'bmr':mybmr }) else: form = BmrForm() return render (request , 'home.html' , {'form': form}) any idea how can achieve that ?
