Django POST method returns 500 server error on EC2 server
I am trying to build a web app using Django Rest framework. When I run the app on localhost 127.0.0.0/8000 it works fine. But when I deploy it on an EC2 server the POST methods return 500 server error. Here is one of the post methods in the views.py - class customer_location(APIView): def post(self, request, *args, **kwargs): customer_id = json.loads(request.body).get('customer_id') queryset = customers.objects.filter(cid= customer_id) serialize = customer_details(queryset, many=True) return Response(serialize.data, status=status.HTTP_200_OK) The urls.py is like this - from django.conf.urls import include, url from django.urls import path from rest_framework import routers from . import views urlpatterns = [ url(r'^customer_location/$', views. customer_location.as_view(), name='customer_location'), ] The DEBUG mode is set to False and the EC2 instance IP address is added in the ALLOWED_HOSTS. The GET methods are working fine but the POST methods give error. How to solve this ? -
Queryset with different datasets based on obj type
I want to implement in my application something similar to instagram's local notifications. The main problem is that local notifications can be different types. For example: 1) Simple one: "user started following you" (this is pretty straightforward) 2) More complicated: "user and +7 other liked your photo X" The first step of solution is to GROUP all notifications by targeted_user, event_type and user_who_triggered_event. For the first case it's okay as we will have all information. For the second case we will lack some information as Count of similar notifications. Also what if I need some additional information about those +7 user's who also liked photo X? class Notification(TimeStampedModel): OPEN_QUEST = 'open_quest' OPEN_PHOTO = 'open_photo' ACTION_CHOICES = ( (OPEN_PROFILE, _('Open profile')), (OPEN_PHOTO, _('Open photo')), ) LIKED_PHOTO = 'liked_photo' NEW_FOLLOWER = 'new_follower' EVENT_CHOICES = ( (LIKED_PHOTO, _('Liked photo')), (NEW_FOLLOWER, _('New follower')) ) action = models.CharField( max_length=255, choices=ACTION_CHOICES, ) event = models.CharField( max_length=255, choices=EVENT_CHOICES, ) title = models.CharField( max_length=255, ) body = models.TextField() class Meta: db_table = 'notifications' For this example I have 2 notifications in data base.

Is it possible to have a hosted Django site use the client's interfaces to create a SSH session with a local privately addressed device
I am trying to learn programming to expand my horizons a bit. I have been creating a Django app that automates several aspects of my day to day job. It would be nice if that Django app could be on a public server for accessibility but also have a view that can initiate an SSH session with various privately addressed devices, mostly to verify network changes were successful. In my mind the script would almost need to run on the client side to use their IP address within the private network but from my understanding, Django is server side. Any advice on how to work around this? -

Is it recommended to manually redirect sub-domains to an application from the project itself?
We have different types of users whom we'd like to redirect to different views based on the sub-domain in the URL. In our project directory, we examine each and every request for the sub-domain keywords, viz. ut1.domain or ut2.domain. Is this a good solution? If not, please suggest something better. User Type 1 ut1.domain.com/login/ User Type 2 ut2.domain.com/login/ This is how the sub-domains are being planned to be handled. def handle_urls(request): if "ut1.domain." in request.build_absolute_uri(): return HttpResponseRedirect('login/') context = {} return render(request, "home.html", context) The purpose of the sub-domains is to point to different applications in the same project. We expect to add more than a dozen sub-domains in the next few months for various new applications. Thank you for your time reading this. -

Creating a generic search view in Django
I am struggling to create my custom generic view in django to easily create search pages for certain models. I'd like to use it like this: class MyModelSearchView(SearchView): template_name = 'path/to/template.html' model = MyModel fields = ['name', 'email', 'whatever'] which will result in a view that returns a search form on GET and both form and results on POST. The fields specifies which fields of MyModel will be available for a user to search. class SearchView(FormView): def get_form(self, form_class=None): # what I'v already tried: class SearchForm(ModelForm): class Meta: model = self.model fields = self.fields return SearchForm() def post(self, request, *args, **kwargs): # perform searching and return results The problem with the code above is that form will not be submitted if certain fields are not be properly filled. User should be allowed to provide only part of fields to search but with the code I provided the form generated with ModelForm prevents that (for example because a field in a model cannot be blank). My questions are: Is it possible to generate a form based on a model to omit this behaviour? Or is there any simpler way to create SearchView class? I don't want to manually write forms if … -

Django throws a 404 error on all static files while everything seems to be correct
Recently, I added some static files to my project which for some reason threw an error (I can't remember what kind of error.) I removed these files and redeployed but now, when I push my Django project to the docker container, the static files have stopped working all together, while everything seems to be in order. These are the settings I use for the static files: STATIC_ROOT = str(ROOT_DIR("staticfiles")) STATIC_URL = "/static/" STATICFILES_DIRS = [str(APPS_DIR.path("static"))] STATICFILES_FINDERS = [ "django.contrib.staticfiles.finders.FileSystemFinder", "django.contrib.staticfiles.finders.AppDirectoriesFinder", ] I am running the installation in a Docker container, taken from the django-cookiecutter project. I have only changed one thing in the Docker configuration, I removed the Postgres image, since my container connects to an external postgres server. I have tried running manage.py collectstatic, and manage.py collectstatic --clear, to no avail. Also, when I run manage.py findstatic --verbosity 2 css/custom.css, I get a message saying that the file was found, with a list of all the folders searched, which does include the static folders for all my apps inside my project. (There are no static files located outside of default folders.) At this point, I'm pretty lost as to what could be the issue. My best guess would that … -

I am using django-rest-marshmallow along with django-rest-framework to build simple APIs. The following works if I dont include the created_at field in the serializer and gets the results as expected but upon inclusion, it throws and exception. models.py from django.db import models class Category(models.Model): name = models.CharField(max_length=50) created_at = models.DateField() serializers.py from rest_marshmallow import Schema, fields class CategorySerializer(Schema): id = fields.Integer() name = fields.String() created_at = fields.Date() # works, if I dont include this views.py from rest_framework import viewsets class CategoryViewSet(viewsets.ModelViewSet): queryset = Category.objects.all() serializer_class = CategorySerializer This results in the following error Django version 2.2.5, using settings 'app.settings' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C.

Django database design for dynamic fields with inheritance

For example: class Templates(models.Model): name = models.CharField(max_length=255) descripton = models.TextField() content = models.TextField() class Meta: abstract = True class TemplateTest1(Templates): class Meta: verbose_name = "Test 1" class TemplateTest2(Templates): class Meta: verbose_name = "Test 2" And these are the document models: class Test1(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) template = models.ForeignKey(TemplateTest1, on_delete=models.CASCADE) class Test2(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) template = models.ForeignKey(TemplateTest2, on_delete=models.CASCADE) Now the templates should contain various variables. If a user create a document he must filled the variables. Some variables should filled from the system automatically. These variables get the data from the database itself. For example the $system_companyname in the content from TemplateTest2 should show the name from the company that the document is created for.
