How does Elastic Beanstalk work behind the scenes for Django?
For running django applications locally I can do django-admin startproject djangotest python djangotest/manage.py runserver and the sample webpage shows up at http://127.0.0.1:8000/ However, when I deploy this to EB with eb deploy It just magically works. My question is does EB runs the command python djangotest/manage.py runserver on the EC2 server after eb deploy by default? What are the list of commands that EB executes to get the webpage working? What if I want it to run with different flags like python djangotest/manage.py runserver --nostatic is that possible? -

Django migrate getting OperationalError
I'm fairly new to Django, am using 1.10. I reached a point where I was unable to migrate because of an error, and so backed up to an earlier migration using ./manage.py migrate myapp 0003_auto_20160426_2022 and deleted the later migration files. I then repaired my models.py and ran makemigrations, which worked fine. But when I attempted to migrate, I received the following error (only showing last few lines) File "/Users/wahhab/Sites/rts/env/lib/python3.5/site-packages/MySQLdb/connections.py", line 280, in query _mysql.connection.query(self, query) django.db.utils.OperationalError: (1022, "Can't write; duplicate key in table '#sql-72_4a6'") I don't know how to move forward from this point so that I can continue working on my project. I have data in other apps but only a little test data in this new app so far, so I have considered deleting all migrations and the mySQL tables for this app and starting over, but I don't want to create a worse mess than I have and don't know what is causing this error. Any advice is welcome. Thanks! -
limited number of user-initiated background processes
I need to allow users to submit requests for very, very large jobs. We are talking 100 gigabytes of memory and 20 hours of computing time. This costs our company a lot of money, so it was stipulated that only 2 jobs could be running at any time, and requests for new jobs when 2 are already running would be rejected (and the user notified that the server is busy). My current solution uses an Executor from concurrent.futures, and requires setting the Apache server to run only one process, reducing responsiveness (current user count is very low, so it's okay for now). If possible I would like to use Celery for this, but I did not see in the documentation any way to accomplish this particular setting. How can I run up to a limited number of jobs in the background in a Django application, and notify users when jobs are rejected because the server is busy? -
Prevent serializer creating duplicate items
I would like my serializer to stop duplicated creation of tags if they are the same. I tried adding "unique" to the model field of "name" in the class Tag but this did not work- it wouldn't allow me to create other Movie's that linked to a tag which exists. Check if the field "name" already exists (case insensitive). If the tag "name" exists, just create the FK relationship with the existing tag name & the new movie If the tag "name" doesn't exist, create it Models.py class Tag(models.Model): name = models.CharField("Name", max_length=5000, blank=True) def __str__(self): return self.name class Movie(models.Model): title = models.CharField("Whats happening?", max_length=100, blank=True) tag = models.ManyToManyField('Tag', blank=True) def __str__(self): return self.title Serializers.py class TagSerializer(serializers.ModelSerializer): taglevel = filters.CharFilter(taglevel="taglevel") class Meta: model = Tag fields = ('name', 'taglevel', 'id') class MovieSerializer(serializers.ModelSerializer): tag = TagSerializer(many=True, read_only=False) info = InfoSerializer(many=True, read_only=True) class Meta: model = Movie fields = ('title', 'tag') def create(self, validated_data): tags_data = validated_data.pop('tag') movie = Movie.objects.create(**validated_data) for tag_data in tags_data: movie.tag.create(**tag_data) return movie -

How to exclude a part of a Django template file from processing?
I have a Django template file that has a couple of enormous strings in it (images encoded in Base64). When I use the Django templating engine, it chokes and takes 5 minutes to render the template.

can't upload image in django admin on deployment
I just tried to change(upload) the picture of one of my records in django admin, and when i submit the "save" button, it said that it has changed successfully but nothing is uploaded and also the path of the image_field didnt change!!! I have exactly the same project on my computer and i can upload files without problem, the only thing that is different in my computer and the server that i deployed my project is the mysql driver, i used "python-mysqldb" on my computer and "mysqlclient" on the server.(and it was weird that i couldnt install "python-mysqldb" on the server, it had been installed on the python2, while i wanted to install it on python3) note: i have apache2.4 installed on both server and my computer. so, what is the problem ?! -
How can I prevent a logged in user from accessing a 'Log In' or 'Sign Up' page in Django version 1.9?
I'm pretty new to Python. My problem is that I want to restrict users who are already logged in from being able to visit the log in and sign up pages. Essentially, what I'm looking for is something like the @login_required decorator, that will allow access to these pages for users who are not logged in. So far, I have Looked at other SO questions such as Django-Registration: How to prevent logged in user from registering?, however I've tried the solution here, and it does not work for me. I've searched through the Django Documentation, Django Girls and other websites that offer tutorials for learning Django. Here's my views.py for the log in: def login_view(request): # Login View to begin user session print(request.user.is_authenticated()) if request.method == 'POST': form = UserLogInForm(request.POST) if form.is_valid(): username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') user = authenticate(username=username, password=password) if user is not None: login(request, user) print(request.user.is_authenticated()) return HttpResponseRedirect('/') else: form = UserLogInForm() return render(request, 'login.html', {'form': form}) else: form = UserLogInForm() return render(request, 'login.html', {'form': form}) and the sign up: class signup_view(View): form_class = UserSignUpForm template_name = 'signup.html' # Blank form is requested def get(self, request): form = self.form_class(None) return render(request, self.template_name, {'form': form}) # Form β¦ -
Django Rest Create with a Writable Nested Serializer

django class based view multiple form validatiton

I'm not able to save the Duration Form despite there's a 200 status POST, the data is not being saved to the database. I think my mistake is that I'm not validating it but I'm really not sure how to, and there isn't much information on multiple forms on CBVs in Django. I would really appreciate some guidance and assistance. Thanks -
Adding javascript to a Django redirect (HttpResponse)
I am using a redirect in Django from django.shortcuts import redirect What I want, is for the user to be displayed a Javascript alert message before being redirected. Here is what I've got so far: response = redirect("someUrl") response.write('<script>alert(\'You must remove an item before adding another\');</script>') response['location'] += "?active=" + "all" return response The redirect works, but the Javascript does not. I also tried response = HttpResponse('<script>alert(\'You must remove an item before adding another\');</script>') return response This triggers the alert window, but I'm not sure how to add an equivalent redirect as the method above. -

Django IOError 13 - permission denied when trying to write to static file

Expected type 'Union[str, unicode]', got 'CharField' instead
I'm working on django using mysql. When I try to load data from AWS mysql server I'm getting an error: django.db.utils.DataError: (1406, "Data too long for column 'key' at row 1") My thinking is it has to do with an error in my models.py file. PyCharm is showing this message in my code - highlighted in yellow, not from running the file -: Expected type 'Union[str, unicode]', got 'CharField' instead This is the class I wrote, edited for putting up here: class ClassName(models.Model): item1 = models.ForeignKey("Another_class") item2 = models.CharField(max_length=2000) item3 = models.IntegerField(default=1) def __str__(self): return self.item2 def get_classname_url(self, parameter1, parameter2, parameter3=1): return "http://website.com/" + str(parameter1) + "_" + str(parameter2) + "_" + str(parameter3) + "a_defining_string" + self.item2 My guess on how to load the data is to correct this Union/CharField issue. As you can see, I've tried to increase the CharField(max_length) to 2000 even, though I understand why this wouldn't work. I've also tried to change it to a TextField, and also understand why this wouldn't work. But worth a shot I suppose. What do you all think would be a solid work around this? Also, why is PyCharm expecting unicode? -
Allow only one instance of a model in Django
I would like to control some configuration settings for my project using a database model. For example: class JuicerBaseSettings(models.Model): max_rpm = model.IntegerField(default=10) min_rpm = model.IntegerField(default=0) There should only be one instance of this model: juicer_base = JuicerBaseSettings() juicer_base.save() Of course, if someone accidentally creates a new instances, it's not the end of the world. I could just do JuicerBaseSettings.objects.all().first(). However, is there a way to lock it down such that it's impossible to create more than 1 instance? I found two related questions on SO. This answer suggests using 3rd party apps like django-singletons, which doesn't seem to be actively maintained (last update to the git repo is 5 years ago). Another answer suggests using a combination of either permissions or OneToOneField. Both answers are from 2010-2011. Given that Django has changed a lot since then, are there any standard ways to solve this problem? Or should I just use .first() and accept that there may be duplicates? -
Django internationalization: inheritance of existing .po file

(2) I have '---' in my Select field and i really dont know how to change it. here is my code i speaking about: class LogInForm(forms.ModelForm): class Meta: model = UserModel widgets = { 'password': forms.PasswordInput, 'full_name': forms.TextInput(attrs={'class': 'form-field form-control'}), 'password': forms.TextInput(attrs={'class': 'form-field form-control'}), 'gender': forms.Select(attrs={'class': 'form-control'}), 'email': forms.TextInput(attrs={'class': 'form-field form-control'}), 'about': forms.TextInput(attrs={'class': 'form-field form-control'}), } ^ speaking about the row "gender" -
Why I am getting django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet?
Since I had same abstract model in every app model I have To avoid redundancy I just moved my common abstract model into new app I created and called it common Common Models.py now is from django.db import models LANGUAGE_CHOICES = ( ('E','ENGLISH'), ('F','FRENCH'), ('S','SPANISH'), ) class CommonInfo(models.Model): created = models.DateTimeField("creation date", auto_now_add=True) modified = models.DateTimeField("modification date", auto_now=True) description = models.TextField() class Meta: abstract = True then I added my common app to settings.py And finally, in all my apps I added from common.models import CommonInfo from common.models import LANGUAGE_CHOICES After running the local server this is the error I am getting in terminal (full trace) Traceback (most recent call last): File "manage.py", line 10, in execute_from_command_line(sys.argv) File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django\core\m anagement__init__.py", line 338, in execute_from_command_line utility.execute() File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django\core\m anagement__init__.py", line 312, in execute django.setup() File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django__init .py", line 18, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django\apps\r egistry.py", line 108, in populate app_config.import_models(all_models) File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django\apps\c onfig.py", line 198, in import_models self.models_module = import_module(models_module_name) File "c:\python27\Lib\importlib__init.py", line 37, in import_module import(name) File "C:\Users\Boris\dev\rentout\rentout\lease\models.py", line 94, in class LeaseFilter(django_filters.FilterSet): File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django_filter s\filterset.py", line 181, in new filters = new_class.filters_for_model(opts.model, opts) File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django_filter s\filterset.py", line 456, in filters_for_model cls.filter_for_reverse_field File "C:\Users\Boris\dev\rentout\virtrentout\lib\site-packages\django_filter s\filterset.py", line 104, in filters_for_model filter_ β¦
