Checkbox to select multiple images and download (Django)
I am stuck with implementing a multiple image download using Django. As seen in the photo, I want to download the images that are checked. How am I able to go about doing this using Django and Jquery? I am able to download individual images using html tag but this is not what I need. Any help would be greatly appreciated! Using Jquery, on click of the download button at the bottom of my webapp, I would check for the checkboxes that are ticked and then grab the url of those images and append them to an array. I am stuck from this step onwards. Link to webapp image -

How to restart a django project without refresh session data stored in process/thread space?
In my django project, I store an instance of a complex class in the thread space. This instance is hard to be serialized so it cannot be stored in the database and resumed from database.

As the instance keep a lot of information which takes a very long time to construct again. Is there any way to keep the instance(object that cannot be serialized) when reload django project? Or is there any way to keep the instance and resume it which cannot be stored in database? -

Char is UTF But I Still See Encrypted Letters
When some Korean texts went through the Django server, I printed the 'data' variable just to see if this encryption issue was caused by Python. Fortunately, Korean letters show well: However, when the letters go through the Django templates, it shows like this: Notice the words like \uc57c,\ud734,\ud734,\uc57c,\uc57c \ud734,\uc57c,\uc57c,\ud734,\ud734 Below is the source code of the templates: <!DOCTYPE html> <html> <head> <meta charset="utf-8"/> <title>Group Share</title> </head> <body> <p>{{ user.first_name }} opened {{ room_name }} group schedule</p> <h3>Group Members</h3> <ul> {% for member in group_members %} <li>{{ member.first_name }}</li> {% endfor %} </ul> <div id="group-schedule" class="flex"> </div> <textarea id="chat-log" cols="100" rows="20"></textarea><br> {{ room_name|json_script:"room-name" }} <script charset="UTF-8"> const roomName = JSON.parse(document.getElementById('room-name').textContent); const chatSocket = new WebSocket( 'ws://' + window.location.host + '/ws/groupshare/channel/' + roomName ); chatSocket.onopen = function(e) { const data = JSON.parse(e.data); document.querySelector('#chat-log').value += (data.message + '\n'); document.querySelector('#chat-log').value = (data.new_schedule + '\n'); console.log(data.new_schedule) }; ... ... ...

pre-commit hook to check django migrations
I'm trying to write a pre-commit hook to my Django project that checks for missing migrations. That is, it ensures all changes are reflected in a migrations file. One way to implement this is to PASS the pre-commit hook if the makemigrations command returns no changes. $ ./manage.py makemigrations --dry-run No changes detected And to FAIL the pre-commit hook if it returns something: $ ./manage.py makemigrations --dry-run Migrations for 'myapp': myapp/migrations/0003_auto_20201213_2233.py - Alter field type on event How can I write this pre-commit hook? Is there a better approach than using makemigrations? This is what I have so far but it always passes (I think I need to parse the response): repos: - repo: local hooks: - id: pre-commit-django-migrations name: Check django migrations entry: ./manage.py makemigrations --dry-run language: system types: [python] pass_filenames: false -

Any way to distribute load between microservice api points from inside a celery task?
I have a Django back-end which takes some data and does some heavy processing on it which might take up to one minute. There is a microservice endpoint hosted on different servers which takes in all the data and does the work. Now, I have to send a POST request from inside the celery tasks to those servers. I am facing difficulty on how to actually implement network traffic management and send different requests to different servers (all of them produce the same result). Here is a sample of the celery task: @app.task def execute(**kwargs): ... exec_args = { "code" : code, "filename" : filename, "time" : time, "mem" : mem, "compile_command" : language.compile_command, "run_command" : language.run_command } param = { "input_file_urls": input_file_urls, "input_file_hashes": input_file_hashes, "output_file_hashes": output_file_hashes, "output_file_urls": output_file_urls, "exec_args": exec_args } net_res = requests.post(executor_url, json=param) net_res = net_res.json() ... Now the problem is in the executor_url part. I have different urls how do I load balance between them. -
Model permissions via a ForeignKey relationship
How can I instruct Django that the permissions for a model are resolved via a ForeignKey relationship where those permissions are declared? from django.contrib.contenttypes.fields import GenericForeignKey from django.contrib.contenttypes.models import ContentType from django.db import models class ConfidentialityLevel(models.Model): """ A possible level of confidentiality of stored records. """ name = models.CharField(primary_key=True, max_length=50) class LoremRecord(models.Model): """ Lorem record. """ uuid = models.UUID(primary_key=True) class IpsumRecord(models.Model): """ Ipsum record. """ uuid = models.UUID(primary_key=True) class RecordConfidentiality(models.Model): """ A level of confidentiality for a record. """ record_type = models.ForeignKey(ContentType) record_name = models.CharField(max_length=50) record = GenericForeignKey(ct_field='record_type', fk_field='record_name') level = models.ForeignKey(ConfidentialityLevel) Each ConfidentialityLevel name is used for categorising which users may view (etc.) records. Examples might be secret, embargoed, beta, published. Each RecordConfidentiality instance represents that the particular record (which might be a LoremRecord, or IpsumRecord, etc.) should be confidential only to those users with permission to ConfidentialityLevel level. So permissions will be (for example) view_secret_record, edit_embargoed_record, delete_published_record. The intention is that these apply to any of LoremRecord, IpsumRecord, and any others which might be referenced from RecordConfidentiality. How can I implement authentication so that users can only perform an action on the record, if they have the ConfidentialityLevel permission corresponding for that record? -

Is it possible to runserver with django without makemigrations?
I am trying to separate my project into multiple sub projects. Model for users has changed. I have only deleted some unnecessary fields. There are no newly added fields or amended field data. From the existing main project, I have done makemigrations and migrated them all. For example, the User model in the file models.py for the main project would look like this. class User(AbstractBaseUser): password = models.CharField('password', max_length=128, blank=True) username = models.CharField('username', max_length=50, unique=True) email = models.EmailField('email_address', blank=True) phone = PhoneNumberField('phone', blank=True) address = models.CharField('address', blank=True) python manage.py makemigrations and python manage.py migrate is all completed so the user model is set in my database. In the new sub project, the model would look like this. class User(AbstractBaseUser): password = models.CharField('password', max_length=128, blank=True) username = models.CharField('username', max_length=50, unique=True) email = models.EmailField('email_address', blank=True) The sub project is also connected to the same database which the main project is using. If I python manage.py runserver this sub project, ValueError: Dependency on app with no migrations: {application name} occurs. Runserver works properly if i python manage.py makemigrations. Is there any ways for me to not makemigrations and run my subproject server? I don't want to makemigrations because I am still using the … -
Python, Django: django-filter and ForeignKeys
Good morning, I would like to ask if there's a way to use django-filter with the Foreignkey? For example: models.py class Company(models.Model): name = models.Charfield(max_length=50, null=False, blank=False) location = models.Charfield(max_length=50, null=False, blank=False) class Person(models.Model): first_name = models.Charfield(max_length=50, null=False, blank=False) last_name = models.Charfield(max_length=50, null=False, blank=False) age = models.Integerfield() company = models.ForeignKey(Company, null=False, blank=False, on_delete=models.CASCADE) filters.py class PersonFilter(django_filters.FilterSet): class Meta: model = Person fields = [ 'first_name ', 'last_name ', 'company ', ] Right now, I only know how to filter for the whole company and often thats's totally fine, but is there a way to - for example - filter for the 'loaction' or any other values as long it's connected with ForeignKey? And if it's not, is there a better solution than django-filter? Thanks to all of you and a great day! -
How to embed a valid CSRF token in a Django Transactional email hyperlink

I would like the user to be able to click on one of two buttons 'accept'/'decline' within the email body, and execute a request which then my Django application can receive and process. The user needs to be authenticated (its ok if link also does an auto-login). My intuition tells me that it will have to be done via a get() request, with a ton of logic that stores keys, verifies them, log's in the user etc. Is that the only way? -
