Pagination doesn't works on my Django App as expected
I'm trying to paginate, it shows in the address bar that I'm on page 2 but nothing new gets displayed.

Comparing JSONFields in Django
If two models both have JSONFields, is there a way to match one against the other? Say I have two models: Crabadoodle(Model): classification = CharField() metadata = JSONField() Glibotz(Model): rating = IntegerField() metadata = JSONField() If I have a Crabadoodle and want to fetch all the Glibotz objects with identical metadata fields, how would I go about that? If I know specific contents, I can filter simple enough, but how do you go about matching on the whole field? -
how to get Json response formatted differently on django

allauth unverified email remains unverified once verification email expires
I have a custom user model. and I use Django rest auth. the problem is that after sign up when the email is sent. if the user doesn't verify the email before it expires, it seems that it remains stuck like that indefinitely. I was expecting the verification email to be sent again or the user with his email to be deleted but that doesn't happen. I am lost as to what else to do and I can't seem to find any resource that helps. below is my model models.py class User(AbstractBaseUser, PermissionsMixin): username = None email = models.EmailField(max_length=254, unique=True) name = models.CharField(max_length=250) is_staff = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) is_active = models.BooleanField(default=True) last_login = models.DateTimeField(null=True, blank=True) date_joined = models.DateTimeField(auto_now_add=True) slug = models.SlugField(max_length=255, unique=True, blank=True) USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['name'] in my settings.py the user has an expiry date of 2 days ACCOUNT_EMAIL_CONFIRMATION_EXPIRE_DAYS = 2 ACCOUNT_EMAIL_VERIFICATION = "mandatory" -
Post Dynamic form data using Vue and Django
I am using Vue js to post data from a regular .html form to Django. Been using python and Django for a few days now. There is a section of my form which contains an area that allows the user to dynamically add form fields(regular inputs and file uploads). I increment name value by using the index everytime the user adds another row. I am not sure how to go about storing these form data.

Incompatibility between wagtail (my) django storage django-b2
I'm sure that problem is on my side. I try to make github.com/pyutil/django-b2 package (django storage, which uses official backblaze b2sdk). When I uploaded an image, it properly moved to backblaze. However it was not immediately accessible and Wagtail has failed when trying reopen the image (to create thumbnails?) I made an attempt to solve it so, that I want cache copies of media files locally in MEDIA_ROOT, for few days (and then delete local media via cron or so). This works better. Nothing fails, image is uploaded to both locations (my server MEDIA_ROOT and backblaze). The image in wagtailimages_image table has 'file' field: original_images/96ed15fd-e431-4615-9ae7-5744d4e1807f/szob2.png, which is correct relative path in backblaze and in MEDIA_ROOT too. Image is visible everywhere in Wagtail for editation (where proper backblaze url appears). However when I add it to RichTextField, it is not visible in the final page, only is rendered. This come from this place (sure, because I have changed this html tag and it has changed in the page too): wagtail/images/rich_text/init.py: def expand_db_attributes(cls, attrs): try: image = cls.get_instance(attrs) except ObjectDoesNotExist: return '<img alt="">' The get_instance seeks for a proper id but from unknown reason will fail with ObjectDoesNotExist.

If I pickle a string in Python myself, can unpickling it ever be dangerous?
Say we have a Postgres 12 database that has a table called MyClass that has a Text column called notes. Users have the ability to save whatever they wish in this notes field. For the purpose of this question, let's assume that they have somehow bypassed all data sanitation. Could the following lines of code ever be dangerous due to malicious text in obj.notes? import pickle # (obj is a Python3 instance of MyClass using the Django ORM, so obj.notes is always represented as a unicode string) obj = MyClass.objects.get(id=1) pickled = pickle.dumps(obj.notes) unpickled = pickle.loads(pickled) -
Is there a way to hash user ID for use in URI (path)?
Is there a way in Python (Django specifically) to build a url for a file that uses a hashed user ID? I want to use the hashed ID for file authentication. i.e compare request.user.id to the section of the file path. I’ve researched Django’s “make_password” but it seems like overkill for my need. I’ve read about os.urandom but it doesn’t sound like it can be reversed. In the end my goal is to protect user IDs from being a part of URLs, but allow for easy file access authentication/permissions. I appreciate any help. -

Django Crispy Form Not Fitting Bootstrap Modal
I am trying to implement a bootstrap modal form in my Django project and I am attempting to use django-crispy-forms crispy_field to style the form. When I do this, everything works except the crispy fields are running much wider than the modal window. I feel like there's an easy fix here but I can't determine exactly what I'm doing wrong.

Django Migrations Failing
I have two development machines for django projects - tower and laptop. I use a private git repo to keep the projects synchronized. I work on tower for awhile, commit the changes to my git repo (including the database), then do a git pull origin master, and git reset --hard origin/master, and then I work on the laptop when I travel. I seem to have made a mistake somewhere, as when I updated laptop as above, I have an error in my migrations. On tower, all the migrations are current and applied. On laptop, I have several migrations that cannot be applied.

Is it safe to store reset password token in html post form?
I want to add reset/forgot password functionality to my personal express.js app. I decided to implement it in similar way how Django does it. Basically, it generates unique token based on user (id, hashed password, email, last login time and current time, all mixed with unqiue password and salt). Then, user receives that token in his "reset password link". Someone explained it better than me in one of stackoverflow answers. And here is the source code of Django PasswordResetTokenGenerator class I will post my javascript implementation on the bottom. It would be nice if you check it for possible flaws, but it is not my main question :) So, user gets e-mail with "reset password link". Link looks like this https://example.com/reset-password/MQ/58ix7l-35858854f74c35d0c64a5a17bd127f71cd3ad1da, where: MQ is base64 encoded user id (1 in this example) 58ix7l is base36 encoded timestamp 35858... is actual token User clicks on link. Server receives GET request -> server checks if user with that id exist -> then server checks correctness of the token. If everything is OK, server sends user html response with "set new password" form. So far, everything was almost exactly the same how django does it (few minor differences). But now I want to … -

Start Django Application when NON-default databases are down
Currently, in my Django 3 application I have 2 databases defined in my settings: DATABASES = { 'default': dj_database_url.config( default='postgres://postgres:@postgres:5432/postgres', conn_max_age=int(os.getenv('POSTGRES_CONN_MAX_AGE', 600)) ), 'inventorydb': { "ENGINE": os.environ.get("INVENTORY_DB_ENGINE"), "NAME": os.environ.get("INVENTORY_DB_NAME"), "USER": os.environ.get("INVENTORY_DB_USER"), "PASSWORD": os.environ.get("INVENTORY_DB_PASSWORD"), "HOST": os.environ.get("INVENTORY_DB_HOST"), "OPTIONS": { 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'", } }, } My question is, how would I go about starting my application even if the inventorydb is down? I am only using that database in a read-only mode and the application is not dependant on that database. My default database handles the normal "default" stuff for auth, sessions, etc. For more clarification, I am using inventorydb to read data in and post it to a DRF API. I have appropriate models for the db, but my app will not perform any mutations on the database. If my database is down, my application should continue to work regardless of that database state. If the database is down, try to reconnect, if that fails I want to respond with an error. I can't seem to track down any information on how to do this. Any guidance would be great. Thanks! -

Before Django 1.10 I was able to do it using this code class CustomManager(models.Manager): def get_by_natural_key(self, state_name, country): country = Country.objects.get_or_create(name=country)[0] print(country) return State.objects.get_or_create(name=state_name, country=country)[0] State.add_to_class('objects', CustomManager()) State.add_to_class('_default_manager', CustomManager()) But from Django1.10, _default_manager is read-only and I am not sure how to add 'get_by_natural_key' method on default manager of model
