Django looking for wrong path for template file
My django project works in localhost perfectly. And i was trying to deploy it on Ubuntu-Apache. I did git clone And i got this error TemplateDoesNotExist at / Erorr here -> http://devpp.me/ Hum ? and i pay attention to this error message django.template.loaders.filesystem.Loader: /templates/base_layout.html (Source does not exist) This Error came from {% extends 'base_layout.html'%} (/home/ubuntu/django/blog/djangonautic/articles/templates/articles/article_list.html) I hoped Django to search templates in the parent folder ({root}/templates). The right path of it is /home/ubuntu/django/blog/djangonautic/templates/base_layout.html (File is there i checked) Why my Django dosen't looking for it in (root) templates ? in settings.py TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': ['templates', 'front/build'], ... I Guess it is because. Virtualenv I created this in Ubuntu (didn't created in local) Apache configure I was following https://medium.com/saarthi-ai/ec2apachedjango-838e3f6014ab this post. something wrong in settings.py But i don't think this is wrong cause in local it works well... Tell me anything you need to debugging i will answer quickly -

Coding Test(Python) .....Must required. But we can write also in Java
CODING TEST The module to be developed is a pricing engine for a cycle. A cycle can be thought of as high level components - frame handle bar with brakes seating, wheels, chain assembly Each of the above high level components will have parts, for instance, a wheel has spokes, rim, tube, tyre. The pricing module should be able to calculate the price of the cycle given its configuration. For example, price a cycle with tubeless tyres, steel frame, 4 gears. The pricing of the parts is time sensitive, means the cost of a tyre will change with time and the module should support this. A tyre can cost 200Rs from Jan 2016 - Nov 2016, and its price can change to Rs 230 from Dec 2016 onwards. The pricing module should be a command line executable, no graphical ui needed. It can take its input as command line parameters or as a json text file, whatever is convenient to specify in. The inputs to the module will be the list of constituent parts, date of pricing and it will output the price of the entire cycle and also price for each high level component - frame, wheels etc. Modular … -
Make it so either 2 fields are Null or neither of them are in django?
I am making a model for my django app where I want to store some measurements, these measurements will have a reading that must not be Null, and a GPS position stored as Latitude and Longitude. I want to accept measurements where there hasn't been a GPS fix yet, so Latitude and Longitude should be null. And in theory, the sensor will never send a Latitude without a longitude or vice versa. Still, there is nothing in the django app that actually forbids that from happening, is it possible? -

Making a Django web app work with gunicorn
I am interesting in putting nginx and gunicorn in front ob of a Django web app (https://github.com/fiduswriter/fiduswriter). This web runs fine with the usual python manage.py runserver command, but for gunicorn I would need to have the wsgi.py file, which I cannot find anywhere. Therefore, I ask myself whether there is any way to bypass that issue for using gunicorn here. -
Model with a one to one field does not save after save(commit=False)
I have the code blow but other fields of patient_specification will not be saved. The code does not show any error and runs normally.

Files not installing for Django/Python web app
I'm trying to open a web app locally on my laptop and the files aren't installing.

Django React Image wont display
So I recently was trying to deploy my website and I was able to get everything working. However, the images are broken for some reason. I can actually add images to the database fine (easily able to add and change the image itself). However, when I click on the link I go nowhere instead of seeing the image and just see the part of my site that pops up whenever the URL entered isn't part of the API (no error, instead nothing basically shows up). The strange part is that the uploaded images actually get added to my images folder in my project but it seems like Django can't find them afterwards (you can see the image is in the database in my images folder). Here is some of my code: SETTINGS.PY STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR,'staticfiles') STATICFILES_DIRS = [ os.path.join(BASE_DIR,'build/static'), ] STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' REST_FRAMEWORK = { 'DEFAULT_AUTHETICATION_CLASSES': [ 'rest_framework.authentication.TokenAuthentication' ] } MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR),'EZtrade') TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR,'build')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] URLS.PY urlpatterns = [ path('api-auth/', include('rest_framework.urls')), path('admin/', admin.site.urls), path('api/', include('articles.api.urls')), path('rest-auth/', include('rest_auth.urls')), path('rest-auth/registration/', include('rest_auth.registration.urls')), re_path('.*',TemplateView.as_view(template_name='index.html')), url(r'^media/(?P<path>.*)$', serve, {'document_root': … -

Django ckeditor upload image link expires after some hours

Querying related model with parent model id
I have two models: class UserPost(models.Model, Activity): user = models.ForeignKey("auth.User", on_delete=models.CASCADE, related_name='userpost', null=True) title = models.CharField(max_length=300) url = models.URLField(null=True) The second model would be: class UserPostComment(models.Model, Activity): post = models.ForeignKey(UserPost, on_delete=models.CASCADE, related_name='userpostcomment') user = models.ForeignKey(User, on_delete=models.CASCADE, related_name='userpost_comment_user') comment = models.CharField(max_length=1000, blank=True, null=True) TO get the UserPostComment model using the foreignkey post. I did: UserPostComment.objects.get(post_id=post_id) This query only works when I have one UserPostComment entry. When there are more than one comment, It fails. I would get: MultipleObjectsReturned at /comment/268/ get() returned more than one UserPostComment -- it returned 2! Any idea how to fix this? -
