Add multiple hidden fields in Django Form
I'm using Django. I need a form that shows the 3 fields of a class I have created, the idea is that for every time you want to add a new day and time show a new section (I do not know if I explain). I still do not logo to make it work, if someone has any idea they would be grateful.

AWS Aurora database read replica autoscaling - best practices for django project to connect your application to newly created databases?
Using AWS Aurora database service - you can configure master-slave replication and slave autoscaling (e.g. if slave CPU is higher than 75 percent - create a second slave). Newly created database has a new endpoint (host) which is not registered by django yet. What would be the best approach to firstly discover the newly created database and add it to a running django application? I am thinking about pinging every X seconds using, lets say, aws cli and checking how many slaves are there. But the problem with this is if a slave is destroyed by an autoscaling group - my django application would start erroring, so an appropriate handling is also required... -

When using the length method in Django-template, ".length" and "|" Difference between
I am trying to compare the length of a variable in an if statement in a Django-template. I wrote it simply as A code, but it did not work. So I found out the B code through Googleing. I wonder why blog.body> 50 not blog.body | 50 A Code {% if post.contents.length > 50 %} {{ post.over }} ... <a href="{% url 'detail' post.id %}">detail view</a> //post.over is a predefined method in the model that limits the number of characters. {% else %} {{ post.contents}} <a href="{% url 'detail' post.id %}">detail view</a {% endif %} B Code {% if post.contents.length | 50 %} {{ post.over }} ... <a href="{% url 'detail' post.id %}">detail view</a> //post.over is a predefined method in the model that limits the number of characters. {% else %} {{ post.contents}} <a href="{% url 'detail' post.id %}">detail view</a {% endif %} What is the meaning of "|"?

Login a user (Backend) that has an unusable password set (Django)
I Check my Users Credentials outside of the statndard Django Auth methodology in and (Active Directory) and if they exist in the active directory but not in the Django users I make them an account (Also unsure if this is the correct way to do this) user = User.objects.create_user(username=username_param) user.set_unusable_password() I set an unusable password as I do not want to store Passwords on the Django site How would I log a user in based on if they pass my custom AD authentication by username and if they have no password set (in Django) as you cannot perform a check_password() method on the password field as it will always return False The password in the password field for the Django Admin page says Password:No password set.

Creating custom rest driven nodes Django-Viewflow
i'm interested in creating a rest driven process in django-viewflow. I've been reading the official page and by doing so i've arrived to the conclusion that after aquiring the pro version of viewflow to have rest integration, I would still need to make my own rest implementation for the nodes to drive the process. My question is basically if what I understand is true, and if so how could I implement restful nodes to drive the process. -

Django Two Factor Authentication
I have recently been reading through the documentation about django-two-factor-authentication which I found here : https://django-two-factor-auth.readthedocs.io/en/stable/installation.html The documentation is great. However, I'm trying to understand the full requirements for this solution. If I implement this package, do I then need to rely on a third party to complete this solution or can two factor authentication be achieved without a third party? My primary concern is the cost associated with plugging in to third parties. If it can be avoided, obviously I'd prefer free. If it can't be avoided, does anyone have experience with any of the third party providers offering two factor authentication? I've researched Twillio a bit but I know there are others out there who perform this service as well. Thanks in advance for any input. -

Translating dynamic content in django
I have a text that has both static and dynamic part like this. Custom message with %(card_status)s text inside I am in fix as to what the best method there is to translate the text. This is what I currently have, {% blocktrans with obj.card_status as card_status %}Custom message with {{ card_status }} text inside{% endblocktrans %} If I do that, the message generated is msgid "Custom message with %(card_status)s text inside" msgstr "This will be translated" But the problem with this approach is that, no matter what the card_status variable is, the translated text will be same. I tried enumerating the django.po file manually with msgid for each of the card_status's possible values. But that is not being considered, example, msgid "Custom message with ACTIVE text inside" msgstr "This will be translated with ACTIVE text" Can somebody suggest a method or a hack that can be used here. There are many similar questions in stack that I referred, but somehow I am not able to get the solution I require. Hope someone can put an end to this question once and for all for everybody's joy. -

Using Django test framework to access databases from outside django shell
I'm currently working on a project that has two use cases: the first, with my client application remotely accessing my database service with some various api calls (this case works fine); the second, to allow for a locally-run client program to access a copy of my database on the local machine, without having to start up a server process, using the same api calls. I've found the following code to work from within the manage.py shell: from django.test import Client client = Client() resp = client.get("/api/call/path").json() However, I cannot get it to work from outside the manage.py parameters. I first run the following code: os.environ.setdefault("DJANGO_SETTINGS_MODULE", "DataSite.settings") django.setup() But then, when I run the snippets to get the client running, I get the following error: [exception.py:135:handle_uncaught_exception() ] Internal Server Error: /api/call/path Traceback (most recent call last): <Traceback here> OperationalError: could not connect to server: Connection refused Is the server running on host "127.0.0.1" and accepting TCP/IP connections on port 5432?
