Django models slug mixin with unique constrain handling
I have three models Book, Part, Chapter, in my models.py that uses the SlugField. For the Book class, I have written a slug handler in the custom save method that checks if an object exists with the slug. And when it does, it makes it unique by appending a count to it. How do I rewrite the block inside Book's to SlugMixin so that I can use for the rest of the models? models.py ... class SlugMixin(models.Model): slug = models.SlugField(max_length=50, unique=True) class Meta: abstract = True class Book(models.Model): title = models.CharField(max_length=50) slug = models.SlugField(max_length=50, unique=True) def save(self, *args, **kwargs): if not self.pk and not self.slug: slug = slugify(self.title, allow_unicode=True) slug_exists = True counter = 1 self.slug = slug while slug_exists: try: slug_exists = Book.objects.get(slug=slug) if slug_exists: slug = self.slug + '_' + str(counter) counter += 1 except Book.DoesNotExist: self.slug=slug break class Part(models.Model): book = models.ForeignKey(Book, on_delete=models.CASCADE, related_name='parts') title = models.CharField(max_length=30) slug = models.SlugField(max_length=30, unique=True) class Chapter(models.Model): part = models.ForeignKey(Part, on_delete=models.CASCADE, related_name='chapters') title = models.CharField(max_length=40) slug = models.SlugField(max_length=40, unique=True) -

Is there a list of Django imports? [closed]
I would like to create a flashcard deck with Django imports on memrise.com. So far I have this list: https://www.memrise.com/course/5736049/django-imports But this, I created it manually. Is there a complete list of all imports so that I can bulk add them in the deck and every time I (or anyone who uses this flashcard deck to memorize it) don't have to look up on search engines and just have them in mind. Thanks in advance. -

Django multi select ManyToMany widget like the admin group multi select
I am trying to use the FilteredSelectMultiple widget inside of my admin panel similar to how the default groups and user permissions are. enter image description here I have tried to research and it seems most people are using this outside of the admin panel. I still want to use this in my admin panel. I have a couple multi select fields that contain 200+ items and I have to "ctrl" click to select multiple. If I miss the "ctrl" then it resets everything. Was hoping it was easy to use this widget inside the admin panel since I am still learning Django. -
Access Django's Static files on Amazon S3 with 'same-origin' referrer policy
Since Django 3.0, SECURE_REFERRER_POLICY was added and also included on the python manage.py check --deploy command. In order to make to make my Django project read media files from Amazon S3, I previously had mine set to strict-origin-when-cross-origin, as well as a S3 policy allowing for the programmatic user to do everything and another policy that checked if the referrer header was set to my domain (similar to what's been described in this question Amazon S3 Bucket Policy Referer). But that was a very rudimentary hotlink protection and I was advised at the Django Forums to switch to same-origin. However, now my site can no longer get any of its asset files (403 Error) and navigating through django-storages and S3 docs searching for an answer has proved to be tough and fruitless so far. :( Here's what I currently have: On the Django side, I have django-storages configured with: AWS_DEFAULT_ACL = 'authenticated-read' SECURE_REFERRER_POLICY = 'same-origin' STATICFILES_STORAGE = 'storages.backends.s3boto3.S3Boto3Storage' On AWS, I have the following policy (the access policy by referrer has been removed): { "Statement": [ { "Sid": "Allow programatic admin to handle bucket", "Effect": "Allow", "Principal": { "AWS": "arn:aws:iam::xxxxxxxxxxxxxx:user/bucket-manager" }, "Action": "s3:*", "Resource": "arn:aws:s3:::bucket-name/*" } ] } The following … -

Creating a web app in django that creates a video (with moviepy) and plays it: Where to start?
I would like to make a web application where a user can: click a button on a webpage to create a **random video (with moviepy) play that video back on the webpage click the button again to create a new **random video that replaces the existing one ** The random video will be created with a python/moviepy script that downloads a bunch of random video clips from the internet to a directory on my computer. It then compiles them into one video (.mp4 file). I've done the python script bit already which successfully creates the video file. To make the web app bit I have been recommended django and that's where I'm stuck! So far I have installed django and got to grips with the basics .. I have a home page that says "Hello world". My question is where do I go from here? How do I connect my python/moviepy script with django? What steps, apps, components etc, within django should I look into to make this thing? I'm new to coding and looking for some guidance. Thanks! -
Can we use python related api's on the Django templates?
I am new to Django and hence not having thorough knowledge about it. So I am facing a few errors in Django. Currently I am trying to print the type of a variable from the Django template html file as follows: <center><h2>The type of feature list report for version {%type(version)%} is<h2></center> For the above, I am getting the following error: Invalid block tag on line 9: 'type(version)'. Did you forget to register or load this tag? So what's going wrong here? How can we use the python related api's (like type(), strip(), get(), etc) from the html template files? I think inside the {% .... %} we can use python related evaluations. Am I right? Please throw some lights on this . -

How to find which entry contains a string in Django + SQLite

Push changes to data in one Django model to another
I writing an application that has a change control workflow. Users retrieve data for a particular month and then they make edits to it and there is a review phase where they can approve records. There are 2 identical tables a master and a staging table. When the user loads up the application they load data from the master table and can edit it in a crud grid. When they hit the stage button I want that data to get pushed inserted into the staging table. How do i tell my view to do that. The staging table doesnt have the associated records yet, i want the records that are sent back as part of the push to get inserted there rather than doing an update to the master table? Any advice would be greatly appreciated. -

Django fails at sending e-mail in production but works in develoment
I have a django app running in google cloud that sends emails through gmail in production and development, but when I added a new app to the project, using another gmail account, it works in development, but not in production, which is really weird.

Weirdly it works in development but not in production. I don't think gmail is blocking my server IP since it's a google's server. Also the other app using the default settings works. Any help guys? Thanks! -

Why data gets stored on ephemeral file system on heroku and not in db.sqlite 3?
So, I deployed my django app for the first time on heroku. I noticed that the user registrations are saved temporarily in app/admin page for some time. This happens because heroku has a ephemeral file system. The data gets stored on a dyno's file system which when discarded also deletes the data in its filesystem. While my local server adds data to my db.sqlite3 file, the heroku server adds it to its own file system instead of db.sqlite3 file resulting in deletions after some time. Only the data which were intially stored in my db.sqlite3 file are the ones that remain permanently. Without using s3 bucket is it possible to resolve this issue so that any future registrations in my app on heroku live server are stored permanently (in my db.sqlite3 file like my local server does)? My settings.py file (databases code) I assume changes here in this block of code will be the only reason to change database storage settings. I can edit the question in future to add more of any code if needed to resolve the issue. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), } } If not possible, any enlightenment as to why …
