How to inject data in a template out of context in html django? form python
forms are passed to the template, which are loaded dynamically depending on the record in the database. that is, in a loop I add shape objects with a key in the form of a number you need to display all forms in a loop in html views class OrderAddView(TemplateView): template_name = 'orders/order_add.html' def get(self, request, *args, **kwargs): context = super().get_context_data(**kwargs) related = self.checkRelated() if related: tag = 0 for x in related: tag += 1 formPath = x.module_name + '.forms' app_form = importlib.import_module(formPath) context[tag] = app_form.RelatedAddForm context['count_form'] = range(1, tag+1) formOne = SimpleOrderAddForm() formOne.prefix = 'one_form' context.update({'formOne': formOne}) return self.render_to_response(context) html <form action="{% url 'order_add' tag %}" method="post"> {% csrf_token %} {% for x in count_form %} {{ context[x].as_p }} {{ x.as_p }} {% endfor %} {{ formOne.non_field_errors }} {{ formOne.as_p }} <button type="submit" class="btn btn-primary btn-block">Add order</button> </form> forms do not appear! how to specify a reference to an object by this key in a loop? if I output directly, for example {{1.as_p}}, it outputs the form, but if {{x.as_p}} is in a loop, where x = 1, it doesn't. how to be print context form {'tag': 'fast', 'view': <orders.views.OrderAddView object at 0x0000000007422DF0>, 1: <class 'clients.forms.RelatedAddForm'>, 'count_form': range(1, 2)} -

django admin url raises error 500 on heroku

Django Integrity Error: null value in non-existent column
I am working on adding a foreign key relation between two models (Experience & Scheduler) in Django. When I originally went to add the foreign key of Experience to Scheduler, I ended up receiving an integrity error. I then removed the foreign key relation and updated my models accordingly so I could test. This still resulted in an error when I went to save my Scheduler object (I don't 100% remember but I'm pretty sure it was still an IntegrityError). I looked into some different solutions to this and I decided to run python manage.py flush to clear the database entirely because I'm on my local host and my own branch. The integrity error is still there even after wiping the database and removing the foreign key relation and I do not know why. I have been trying to figure out what the failing row represents because it doesn't look like either one of the models. The only thing I have discovered about it is that when I refresh my error page, index 0 of the column increments by one. Experience Models: from django.db import models class Experience(models.Model): type = models.CharField(max_length = 10, null=False, blank=True) description = models.TextField(max_length=100, null=False, blank=True) … -

How to implement something like f-string, which calls conditional_escape()?
I like f-Strings in Python. And I like Django's SafeString. I know Django's format_html() method, but f-Strings are easier to use.

Pushing data from an api response to an active django channel
I am new to django channels and figuring out a way to push a response from an api to an active websocket connection. Here I have a chat with two users and if I am sending a response from an api, I need to show that message from the api response to the active room. I have something like this now for testing. async def send_message_from_api(message, chat): channel_layer = get_channel_layer() chat_room = f"chat_{chat}" await channel_layer.group_send( chat_room, { 'type': 'websocket.send', 'text': message, } ) and in django rest post function, something like this, ChatConsumer.send_message_from_api(serializer.data, chat.id) This might be a dumb try, but it doesn't work. Can someone suggests a proper way to do it? or can modifying this code make it work? Thanks -
Django: Resolving "Reverse for 'password_reset_complete' not found."
I am attempting to do a password reset using Django using custom html templates. I am able to request an password reset by email (using the EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend'), and I then get an "email" in the console, as I would like. The email does lead me to the "password_reset_confirm.html" page as I would like, and I can input the new passwords for the user associated with the user. However I am getting the following error when I click the "Reset password!" button: "Reverse for 'password_reset_complete' not found. 'password_reset_complete' is not a valid view function or pattern name." Despite this error, the password does actually change, however I (obviously) do not want this error.
