How to run tests in Django app? Setting error
I try to write tests for my Django app but I'm getting an error and don't know how to fix it. Inside my sport_field_app folder I have files: conftest.py: import pytest from django.test import Client @pytest.fixture def client(): client = Client() return client tests.py: def test_list(client): response = client.get("sport-field-list/") assert response.status_code == 200 I've also added a file pytest.ini: [pytest] DJANGO_SETTINGS_MODULE = test.settings After running pytest test.py I got a message: Traceback (most recent call last): File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/pytest_django/plugin.py", line 179, in _handle_import_error yield File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/pytest_django/plugin.py", line 351, in pytest_load_initial_conftests dj_settings.DATABASES File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 87, in __getattr__ self._setup(name) File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 74, in _setup self._wrapped = Settings(settings_module) File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/django/conf/__init__.py", line 183, in __init__ mod = importlib.import_module(self.SETTINGS_MODULE) File "/usr/lib/python3.8/importlib/__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1014, in _gcd_import File "<frozen importlib._bootstrap>", line 991, in _find_and_load File "<frozen importlib._bootstrap>", line 973, in _find_and_load_unlocked ModuleNotFoundError: No module named 'test.settings' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/bin/pytest", line 8, in <module> sys.exit(console_main()) File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/_pytest/config/__init__.py", line 187, in console_main code = main() File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/_pytest/config/__init__.py", line 145, in main config = _prepareconfig(args, plugins) File "/home/maryla/marylaGIS_github/sport_field_reservation_v2/venv/lib/python3.8/site-packages/_pytest/config/__init__.py", line 324, in _prepareconfig config = pluginmanager.hook.pytest_cmdline_parse( … -

Django, generic view dynamic filtering
i'm starting out with Django and trying to render all Shows(screenings) that selected Movie had.

nginx alias : where is the alias taking place (3 containers and a reverse proxy)
Im trying to get working a single page application with django/wagtail and react. But at the moment im serving django content via restframework and the request on media/ and djangostatic/ are not working. I have configured nginx to serve /media and /djangostatic to alias /app/media and /app/static but this is not working properly. Here is the nginx.conf file: server { listen 80; server_name localhost; location / { proxy_pass http://172.20.128.3:3000; proxy_set_header Host $host; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 20M; } location /wagtail { proxy_pass http://172.20.128.2:8000; proxy_set_header Host $host; proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Script-Name /wagtail; client_max_body_size 20M; } location /djangostatic/ { alias /app/static/; } location /media/ { alias /app/media/; } } When a page in need of /djangostatic is querried, i get the error : 2022/06/12 08:30:10 [error] 22#22: *2 open() "/app/static/wagtailadmin/js/vendor/jquery.datetimepicker.js" failed (2: No such file or directory), client: 172.20.0.1, server: localhost, request: "GET /djangostatic/wagtailadmin/js/vendor/jquery.datetimepicker.js?v=021047c1 HTTP/1.1", host: "localhost", referrer: "http://localhost/wagtail/cms-admin/login/?next=/wagtail/cms-admin/" So the alias seems to work (it is replaced by /app/media) but it doesnt open the file.

How can I simplify retrieval of corresponding foreign key objects
I use Django on the backend and React on the frontend. I have quotes that are related to a character by foreign key, for example: class Quotes(models.Model): quote = models.CharField(max_length=1000, unique=True, null=True, blank=False) quote_ja = models.CharField(max_length=1000, unique=True, null=True, blank=True) quote_by = models.ForeignKey(Characters, on_delete=models.SET_NULL, null=True, blank=True) quote_from = models.ForeignKey(Media, on_delete=models.SET_NULL, null=True, blank=True) date_added = models.DateField(auto_now=True) I have some models with multiple foreign keys, for example in the above, quote_by returns the keys to the corresponding characters. image of the foreign keys in api This is the Characters Model connected to quote_by: class Characters(models.Model): first_name = models.CharField(max_length=100, null=True, blank=False) last_name = models.CharField(max_length=100, null=True, blank=True) ja_name = models.CharField(max_length=100, null=True, blank=True) image = models.ImageField(upload_to='characters/', null=True, blank=True) I would like to access the data from fields such as quote_by/quote_from with React. At the moment it seems overly complicated and I'm wondering if I should make a change to the backend. -

Link to detailpage of object with todays date from navbar

How to pass a value to a Bootstrap modal in Django
I'm trying to implement a feature where I get to change a product by passing its id to a modal and change it there, then reflect the changes in the same page, where the user can click on the product name, a modal page appears with the product name and a list of products, then he can change the product from the list of products, click save changes, the modal page closes, and the product is now updated. The problem is that I was facing difficulty in passing the product id to the modal div that exist in the same template, but couldn't figure it out, then I saw Martín De la Fuente's approach and tried it, but it didn't work with me as well. It shows me this error message: django.urls.exceptions.NoReverseMatch: Reverse for 'products_modal' not found. 'products_modal' is not a valid view function or pattern name. My code is as the following: In product template: Sending product id to the product_modal template: <td> <a href="#" class="open-modal" data-url="{% url 'products_modal' product.id %}"><span>{{product.name}}</span></a> </td> Creating an empty div to insert the product_modal in it: <div id="product-modal-div"></div> Javascript part: <script> var productModalDiv=$("#product-modal-div") $(".open-modal").on("click",function(){ $.ajax({ url:$(this).attr("data-url"), success:function(data){ productModalDiv.html(data); $("#ProductModal").modal(); } }) }) </script> … -

How to get and update complete querySet in django model
please I am having issues with my code. Model class: class Skill(models.Model): class Meta: verbose_name = ".4 skill" class SkillCategory: categories = (("frontend", "frontend"), (" backend", "backend") title = models.CharField(max_length=255) category = models.CharField(choices=SkillCategory.categories, max_length=255) Views.py: def edit_skill(request): get_data = Skill.objects.get(pk=1) In my case from the code snippet in views.py am supposed to get a <QuerySet [<Skill: HTML>, ...]> everything works fine. My problem came in when I needed to update a particular data in my Skill model using primay key(pk), in this manner: get_update_data = Skill.objects.get(pk=1) for skill in get_update_data: skill.title = " ReactJs" skill.category = "frontend" if skill.save(): return JsonResponse({"data": 200}) return JsonResponse({"data": 500}) Problem: From the above, I incurred a Python bug stating: get_update_data is not iterable. After deploying other debugging method I discovered that in my QuerySet I got a returned data of Skill with only title, and which in my update I needed to update title and category. Please I am confused at this point on the approach to take in fixing the bug and I will appreciate an helping hand at this point. Thank you for your anticipating assistance. -

How to resolve "NoReverseMatch" Error in Django?
So I'm trying to create a table of hosts, and as one of the fields of that table include a clickable link to an update page. Which will pass the host_id to the update page.

Unable to save webp file to model field
I'm not sure if this is entirely django related, but if someone could help me, that would be so much appreciated! I'm having trouble generating a webp file from the following code from io import BytesIO from PIL import Image import requests I've got the following model class UserImage(models.Model): user_provided_image = VersatileImageField(upload_to=folder10, null=True, blank=True) nextgen_image = models.FileField(upload_to=folder10,null=True, blank=True) #for WebP images I'm creating a webp file. This code works, but it saved it to the file to the root directory of my project and I'm not sure how to save it to the FileField (i.e. nextgen_image ) on my model def create_webp_image(sender, instance, *args, **kwargs): image_url = instance.image.thumbnail['1920x1080'].url try: response = requests.get(image_url, stream=True) path = image_url except: #local env path = "http://localhost:8000" + image_url response = requests.get(path, stream=True) img = Image.open(BytesIO(response.content)) #build file path position = path.rfind("/") + 1 newpath = path[0:position] #build file name image_name = path[position:] name_of_file = image_name.split('.')[0] + ".webp" #this creates the webp file img.save(name_of_file,"webp") #save image to model #instance.nextgen_image = ? post_save.connect(create_webp_image, sender=UserImage) Thanks! -
"Tainted canvases may not be exported" even after allowing all URLs with Django CORS Headers module
Using Django, I'm attempting to pull a texture from textures.minecraft.net, crop, zoom, and display a section of said texture. CORS of course has a problem with this. In response to this, I've installed the pip module "django-cors-headers" and set up my settings according to the instructions here. Here's what my settings.py looks like: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'corsheaders', # here it is 'users.apps.UsersConfig', ] MIDDLEWARE = [ 'corsheaders.middleware.CorsMiddleware', # here it is 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] CORS_ALLOW_ALL_ORIGINS = True # Yes, it's unsafe. I just want a working prototype for now CORS_ALLOW_CREDENTIALS = True I have a JS that attempts to create a new image with the source of the above texture. Here's the JS snippet: let skin = "http://textures.minecraft.net/texture/74d1e08b0bb7e9f590af27758125bbed1778ac6cef729aedfcb9613e9911ae75"; let testImg = new Image(); testImg.height = 64; testImg.width = 64; testImg.setAttribute('crossorigin', 'anonymous'); testImg.src = skin; This script is loaded in VIA django like so: <!-- Load the JS script into the base html on this page --> {% block bodyscripts %} <script src="{% static 'js/test.js' %}" defer></script> {% endblock bodyscripts %} My Pipfile contains: django-cors-headers = "*" Yet I still receive the error "Access to image at 'http://textures.minecraft.net/texture/74d1e08b0bb7e9f590af27758125bbed1778ac6cef729aedfcb9613e9911ae75' from origin … -
Django: save multiple images on upload
I want to save multiple versions of a picture and based my solution on this thread: Django / PIL - save thumbnail version right when image is uploaded The model Class overrides the save() function, which calls the make_thumbnail() function, to scale the image. The issue is, that this code, does not save the uploaded file, but it takes the default image. Where is the issue? models.py pic_formats = [(640, 480), (1280, 960), (1920, 1440) ] def path_and_rename(path, sufix=None): def wrapper(instance, filename): file_extension = filename.split('.')[-1] # get filename if instance.pk: filename = f'{instance.pk}_{sufix}.{file_extension}' else: # set filename as random string filename = f'{uuid4().hex}.{file_extension}' # return the whole path to the file return os.path.join(path, f'user_{str(instance.pk)}', filename) return wrapper class UserProfile(models.Model): email = models.OneToOneField(User, on_delete=models.CASCADE) # Profile Pictures profile_pic_orig = models.ImageField(upload_to=path_and_rename(path='img/profile_picture/', sufix='orig'), default='img/profile_picture/default.jpg', verbose_name=_('profile picture')) profile_pic_640 = models.ImageField(upload_to=path_and_rename(path='img/profile_picture/', sufix='640'), default='img/profile_picture/default_640.jpg', verbose_name=_('profile picture 640px'), null=True) profile_pic_1280 = models.ImageField(upload_to=path_and_rename(path='img/profile_picture/', sufix='1280'), default='img/profile_picture/default_1280.jpg', verbose_name=_('profile picture 1280px'), null=True) profile_pic_1920 = models.ImageField(upload_to=path_and_rename(path='img/profile_picture/', sufix='1920'), default='img/profile_picture/default_1920.jpg', verbose_name=_('profile picture 1920px'), null=True) def make_thumbnail(self, formats: list): from PIL import Image from io import BytesIO from django.core.files.base import ContentFile from django.core.files.uploadedfile import SimpleUploadedFile import copy image = Image.open(BytesIO(self.profile_pic_orig.read())) thumb_name, thumb_extension = os.path.splitext(self.profile_pic_orig.name) thumb_extension = thumb_extension.lower() if thumb_extension in ['.jpg', '.jpeg']: FTYPE = 'JPEG' …
