Django deployment on Heroku - Complaining about secret key
I have just created a new django project, right now there are no apps besides one for settings, there are also no urls etc yet. I have set it up to deploy to Heroku, with a ENV variable to load the appropriate settings file (staging in this case). I copied the settings file that Django creates by default to base.py. This includes the secret key. Then in my __init__.py in my settings app I have the following code: from .base import * env_name = os.getenv('ENV', 'local') print("env name: " + env_name) if env_name == 'PRODUCTION': from .production import * elif env_name == 'STAGING': from .staging import * else: from .local import * The heroku build logs show that it loads the correct settings: -----> Python app detected cp: cannot stat '/tmp/build_1479228f_/requirements.txt': No such file or directory -----> Installing pip 9.0.2, setuptools 47.1.1 and wheel 0.34.2 Skipping installation, as Pipfile.lock hasn't changed since last deploy. -----> Installing SQLite3 -----> $ python manage.py collectstatic --noinput env name: STAGING 132 static files copied to '/tmp/build_1479228f_/staticfiles', 418 post-processed. -----> Discovering process types Procfile declares types -> web -----> Compressing...

running custom migrations to change database schema

How can I use or override the WriteView in django-postman to send an email through django?
According to the documentation (see docs), you can supersede the default view to return to, i.e. by passing in a success url in the urlpatterns. The problem, however, is that I would like to you use the built-in WriteView so that every time a message is submitted I can use the send_email() function from django to send an email. One solution that I have tried is to send a mail in a context processor, meaning that every time a user navigates to a page I look if there has been a message sent recently, and together with a stored session key, can see if I should send an email or not. This seems to create a lot of overhead, and if someone were to submit multiple times before a page is done refreshing (hence the session key has not registered yet), a user would receive multiple emails. Does anyone know of a way to do this? I would appreciate any help I can get. -

Django SessionAuthentication deletes older session entries from database when user login with new session
Django Version: Django 2.2 Python Version: 3.6 Calling any Authenticated API from the device with the older session has a query below, which is not intentional as per application logic, this automatically prevents users from multiple device login, but I want to allow our users to create multiple sessions across the devices. Any idea about this behaviour in the Session Authorization class in Django? as per my investigation docs says that, multi sessions are allowed by default, but that's not the case for me.

Change Database schema and migrate Models
I had two models Item and Module separately Polymorphic Models: from polymorphic.models import PolymorphicModel Class Item(PolymorphicModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) class Module(PolymorphicModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) description = models.TextField() I want to change the database schema without causing any problems with the existing data in database: Change needed: Class Item(PolymorphicModel): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) class Module(Item): description = models.TextField() As in code above, i want to inherit the Module table from Item table. I removed the uuid field since it clashes. Now i want to make my existing data safe .I am trying to run a management command which creates items first from the module Id. Any way i can achieve my target or is there any better way to do this? What i have tried: First i run a management command which loops through all modules and create tenant share items with exact same Ids. Now im trying to change the db and it asks how to popupulate existing rows -
How to properly add a wsgi application to an existing static website without specifying a WSGIScriptAlias in Apache?
I've got a situation where I have an existing static website that I am trying to add a Django application too. The django application itself is one django project but contains two distinct, unrelated components that I want to list at different URLs and not have them be under the same subURL. So what I have now is a static HTML website at example.com/index.html and a Django application with an app based at /foo and another at /bar and I would like these to live at example.com/foo and example.com/bar respectively. However, I can't figure out how to make this happen. It seems that I need to set the WSGIScriptAlias but I'm not sure how to do that without the WSGIScriptAlias to something like /p giving me something like example.com/p/bar and example.com/p/foo. I know that I could set it to / and I tried that, which gives me the desired URLs for the django application but breaks the static site. If I do this, the redirect to index.html no longer works (because the django application doesn't contain an index.html) and all the other links no longer work (I assume because all urls are being redirected to /?) but I assume there … -
Can someone explain me how to fix this issue with a django stock app?
So I'm creating a stock blog in django and I have the following problem, the thing is that when I want to create a post, I want it to automatically select the symbol from the str: parameter it was in the link before, for example, I'll demonstrate with images what I want to do: There in the link, it says microsoft, and when I click on add post, I automatically want to fill in microsoft, and I want to automatically fill this with msft, which is in the database. Here's the code if you can give me any ideas I'll show the post parts: views.py class AddPostView(CreateView): model = Post form_class = PostForm template_name = 'app1/createpost.html' def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) models.py class StockNames(models.Model): name = models.CharField(max_length=255) symbol = models.CharField(max_length=255) def __str__(self): return self.symbol class Post(models.Model): title = models.CharField(max_length= 255) header_image = models.ImageField(null = True, blank = True, upload_to = 'images/') author = models.ForeignKey(User, on_delete=models.CASCADE) body = RichTextField(blank = True, null = True) #body = models.TextField() post_date = models.DateField(auto_now_add=True) category = models.CharField(max_length=255, default='coding') snippet = models.CharField(max_length=255) likes = models.ManyToManyField(User, related_name = 'blog_posts') stock = models.ForeignKey(StockNames, null=True, on_delete = models.CASCADE) urls.py (the third one is the one for … -

How does node + express compete with full fledged framework of python + Django?
I tend to find building with python(Django) easier than with node (express) since there's so many things that need to be added and configured with NPM. My concern is with building a backend that clients can use to inject content into the frontend. Since Django comes well equipped, how can I achieve that interface with node and it's web framework? What do you advice?
