The file "manage.py" did not come with my GitHub sample code
I'm an old-school developer, learning Django and GitHub for the first time. I'd like to study https://github.com/tomwalker/django_quiz, but when installed in my virtual environment, I can't find the file "manage.py". A YouTube Django tutorial suggested I need to run "py manage.py runserver" to start a web server on my local machine. (I was successful starting a server when following THAT tutorial, but I'm now studying source code from GitHub.) There's clearly a difference in age between the sample project on GitHub and my YT tutorial... Can someone please tell me if I'm going about the learning of Django correctly, and if I truly need manage.py to start a server? Thank you! -
Can PyInstaller (or other tools) create an executable file from Django project for production environment?
I want to create an executable file from our Django project. Currently we use Daphne as ASGI server hosting both HTTP and web-socket. I found following link but it seems that PyInstaller is only for Django dev env, not for production. https://github.com/pyinstaller/pyinstaller/wiki/Recipe-Executable-From-Django Am I correct? Is there any other tool allow me to create standalone file for production environment. Many thanks! -

Django - If I get an error while saving a model instance, how do I check which field caused the error?
Let's say I have the following model. This is just an example. The real life version has hundreds of fields. class MyModel(models.Model): date1 = models.DateField() date2 = models.DateField() date3 = models.DateField() When I am saving the model, I get the following error - ValidationError: ["'' value has an invalid date format. It must be in YYYY-MM-DD format."] Basically, one of the datefields received an empty string as opposed to a proper date format. However, I don't know whether date1, date2, or date3 is causing the problem. Is there some easy way to check which field returned this ValidationError? -
Django force_login not logging the Django Client in?
I must be missing something obvious here but I can't see it so maybe you can help ? I'm using Pytest to test a Django form and it's creation of an object. I'm using Django Client object and trying to force_login which according to the result is not working since in the response url contains a redirect to the login page as if the user would not be logged in... Why is this happening, what am I doing wrong and how to fix it? Here's the code: from django.test import TestCase, RequestFactory, Client class TestViews(TestCase): @classmethod def setUpClass(cls): super(TestViews, cls).setUpClass() cls.user = mixer.blend(get_user_model()) cls.patient = mixer.blend('patient.Patient', created_by=cls.user) cls.factory = RequestFactory() @pytest.mark.django_db def test_patient_creation_form_valid(self): c = Client() c.force_login(self.user) response = c.post(reverse('NewPatientForm'), { 'name': 'John', 'surname': 'Smith', 'phone': '601123456', 'email': 'john.smith@gmail.com', }) self.assertEqual(response.status_code, 302) np = c.get(response.url) Thanks! -

Django: get data from array of objects sent by ajax formdata
I would like to access option_rows data that is sent from the front end of the web application. I use an array to store a collection of objects, include text and image, and append it into formdata, send via ajax. The console log of option_rows is as the image below. However, I couldn't access each data in the array. How could I access each element of option_rows? Please also point out what is wrong with the code below as well. Thank for answering. Javascript code: var option_rows = []; option_rows.push([{option_name : option_name, answer : answer, option_img : option_img}]); var formData = new FormData(); formData.append('option_rows', option_rows); $.ajax({ url: "{% url 'add_question' %}", type: 'POST', data: formData, contentType: false, processData: false, cache: false, success: function(){ $("#addModal").html(""); }, }) option_rows log: views.py: def add_question(request): if request.method == 'POST': option_rows = request.POST.get('option_rows') print option_rows print type(option_rows) output: -
How to embed interactive Bokeh or Dash app *with authentication* in Django or Flask?
I know similar questions have been asked here or elsewhere, but I feel like I have read it all and still am unclear on how to solve my specific problem - authentication. I have written a Bokeh app that is interactive, so requires Bokeh server to be run to serve JavaScript. The app is fed by user data from Strava. I would like to make the app available to other people, so I need to include authentication to Strava account. For this reason I thought of incorporating the app in a Django project. From what I have read, there is no "official" way of doing this and my best bet might be spinning the Bokeh app and the Django on their own servers and view the Bokeh app in an iframe HTML element in Django template. But would it be then possible to make the apps somehow talk to each other, so that the authentication I need is made through Django and passed to Bokeh app? Also, would it be possible in such setup for the Bokeh app data to be fed from Django models? I am also willing to switch to other frameworks like Flask and Dash if it … -

Missing Python package from requirements in Docker image built on Circle 2.0
I use CircleCI for continuous integration to build, test, and deploy a Django application, using Docker, ECR on AWS, and Kubernetes. Recently, I updated my CircleCI config file from 1.0 -> 2.0 to comply with required changes. To ensure everything was working properly, I built and deployed the application using the new configuration file and was successful. A couple days ago, I needed to add a new Python package (Shapely) for a new feature to my application, so I added Shapely==1.6.4.post2 to my requirements file - very simple. I can still build, test, and deploy the application from Circle just fine, and everything appears to be working perfectly, however, when the container is running on my servers the Django process will not start because of an import error (can't find module Shapely, basically it isn't getting installed in the image for some reason?!). I can pull the image from ECR and launch a container and confirm that the package does not get installed, however, checking my build logs in Circle confirms that first it got installed and in subsequent builds pulls from the cache, so I am perplexed as to how it isn't included in the image. Interestingly, the container … -

Django and C++ communication
I need to send some data from my C++ program in my client machine to a Django server in order to process the data with Python and send it back to another client machine. That would be easy if it was something like ajax with javascript using json, but the thing is, I researched a lot and found a library for C++ called Wt, it seems to have what I need, but I have no clue of how I would be able to send the data to a Django view. I couldn't find any useful code specific to this problem, I would appreciate if someone could give me a light of how to do so. -
In Django serializer, how do I serialize both sides of a foreign key relationship?
In my Django code, I have this model: class Swipe(models.Model): user = models.ForeignKey( Profile, related_name='swipes', on_delete=models.CASCADE, null=False, default=None ) SWIPE_CHOICES = ( (1, "left"), (2, "right"), (3, "up"), (4, "down") ) direction = models.IntegerField( choices = SWIPE_CHOICES ) where Profile is my user class. I have a view to display all profiles: class ProfileList(generics.ListCreateAPIView): serializer_class = ProfileSerializer queryset = Profile.objects.all() def perform_create(self, serializer): serializer.save() where ProfileSerializer looks like: class ProfileSerializer(serializers.HyperlinkedModelSerializer): # serializations of other fields class Meta: model = Profile fields = ( 'url', 'id', 'username', 'password', 'first_name', 'last_name', 'email', 'swipes', ) This serialization of my Profile class returns just a URL for 'swipes' (e.g. "[host]/swipe/1"). I know this kind of the opposite of how a foreign key relationship is supposed to work, but is there a way for me to serialize this swipe information to display, for example, the direction of the swipe instead of just a URL to the swipe itself? When serializing a Swipe, I can get the serialization of an associated profile to work by adding "user = ProfileSerializer()". However, when I try to add "swipes = SwipeSerializer()" to my code, the swipes field goes from displaying a list of the URLs to an empty map … -

Can't override Django's email subject line
I have a registration folder in my Django app, and I'm using django.contrib.auth.views for all the user log in and registration things. Anyway, I set up my password_reset_form.html and everything works well, except I can't seem to set the email subject line. Every resource I'm finding online says I can just add password_reset_subject.txt to my registration folder (on the same level as all my user html templates), and that should override the django default. However, that's not working. I would be willing to switch to the send_mail() approach but I like how the built in django.auth one sends a tokened link to change_password. Is there any reason my password_reset_subject.txt would be ignored? Thanks in advance. -
