Integrate Django as a consumer with AWS Api Gateway Websockets
I'm not sure how to do it. I've looked for in almost all the network and information is not clear and confuse. I have a websocket done in AWS ApiGateway Websocket. I'm trying to connect to my websocket path from Django, the idea is to pass the information retrieved by Django to HTML to do a dynamic website. I know I can do this directly from the HTML template using javascript but, the websocket is would be open for whatever person and couldn't protect it. For that reason I'm trying to do it by Django. I've found information about channels library but the examples found are not clear due to the Websocket server used on these examples are localhost while my websocket server has a AWS path. I really appreciate your help -

Issue with Django rendering raw queryset to template
i'm pretty new to Django so still trying to understand some concepts. I'm trying to render the text from a simple CharField in a template. I would like this to be used throughout the project so i've made a context_processors.py file to handle this Models.py class HeaderCustomisation(models.Model): small_banner_text = models.CharField(blank=False, null=False, max_length=200, default="Welcome") class Meta: verbose_name_plural = 'Header Customisation' def __str__(self): return self.small_banner_text Views.py def header_customisation(request): header_customisation = HeaderCustomisation.objects.all() context = { 'header_customisation' : header_customisation, } return render(request, 'includes/header.html', context) Context_processors.py from home.views import HeaderCustomisation def header_customisation_processor(request): header_customisation = HeaderCustomisation.objects.all() return {'header_customisation': header_customisation} header.html <div id="delivery-banner" class="row text-center bg-black"> <div class="col free-delivery-wrap"> <h5 class="free-delivery-text my-1">{{ header_customisation }}!</h5> </div> </div> This renders the text from the Model but renders the raw query, like so: If anyone can help or point me in the right direction to only returning the CharField value, that would be much appreciated. Also, if any additional info is needed i'll be happy to provide. Thanks! -

Django virtual env locate
I've bought a new pc, and I downloaded my django project, which was saved in one drive, but when I open it in vs code, I can manipulate the .py files but not any other. I suppose this is because of not having the pipenv enabled. I had saved the pipenv on a pendrive, but how can I activate it now? Here goes a picture of the pipenv folder I saved: 1 2 -

Copy a directory recursively from Google Cloud Storage Bucket to another Google Cloud Storage Bucket using Django
I intend to copy a whole directory with all files and directories recursively from one Google Cloud Storage Bucket to another Google Cloud Storage Bucket. The following code works fine from local to a Google Cloud Storage Bucket : import glob from google.cloud import storage def upload_local_directory_to_gcs(local_path, bucket, gcs_path): assert os.path.isdir(local_path) for local_file in glob.glob(local_path + '/**'): if not os.path.isfile(local_file): upload_local_directory_to_gcs(local_file, bucket, gcs_path + "/" + os.path.basename(local_file)) else: remote_path = os.path.join(gcs_path, local_file[1 + len(local_path):]) blob = bucket.blob(remote_path) blob.upload_from_filename(local_file) upload_local_directory_to_gcs(local_path, bucket, BUCKET_FOLDER_DIR) How can I copy a directory recursively from one bucket to another in the same project ? -

Doesn't django implement Content Security Policy by default?
In a RoR project I had <%= csp_meta_tag %> in the main html file. I was trying to build a conceptual app in Django with the knowledge I had at RoR, but when searching for Django Content Security Policy, only a extension appears (https://django-csp.readthedocs.io/en/latest/). There is no documentation regarding the topic so, is it possible that Django does not solve this common security issue by default? Also, I only found this SO question about this. -
How can I use Wagtail Forms for a Headless CMS? ( without Template )
According to the documentation, Wagtail API is read-only ( POST Method not allowed ). Hence, the only way to use Forms from the Sidebar Menu is using Templates, so the client is capable of making post requests against the API internaly. But that´s not headless. To be headless the API must be capable of receiving form data by providing a URL. Wagtail Docs - API "The Wagtail API module exposes a public, read only, JSON-formatted API which can be used by external clients (such as a mobile app) or the site’s frontend." ... At this point I´m not having the slightest clue, that means at a last resort I have to rethink my stack, although so far I have been very satisfied with Wagtail as headless CMS together with Nuxt as Client. Any ideas to avoid this measure would be much apprechiated. -

Getting ValuError: Field 'id' expected a number but got a html
I am a newcomer, about 10 days into a self-taught Django, and I am building a Django (v3.2) app. The main view in the app is a list of countries (view: CountryListView, template: countries_view.html). When I click on a country in that list, a detail view is brought up to see detailed country data (CountryDetailView and country_detail.html). In CountryDetailView, there are navigation buttons: either back to CountryListView, or 'Edit', which shall bring the user to CountryEditView, where the country parameters can be changed & saved. However, when I click on 'Edit', I get the following error: Request Method: GET Request URL: http://127.0.0.1:8000/manage_countries/countries/country_edit.html/ Django Version: 3.2.4 Exception Type: ValueError Exception Value: Field 'id' expected a number but got 'country_edit.html' I am guessing this might to do something with values returned (or rather expected but not returned) from CountryDetailView, but what they are? And how to make CountryDetailView to return the object id? (I am using plain integer id's in my model) views.py class CountryListView(LoginRequiredMixin, ListView): model = Countries context_object_name = 'countries_list' template_name = 'manage_countries/countries_view.html' class CountryDetailView(LoginRequiredMixin, DetailView): model = Countries template_name = 'manage_countries/country_detail.html' class CountryEditView(LoginRequiredMixin, UpdateView): model = Countries template_name = 'manage_countries/country_edit.html' success_url = reverse_lazy('manage_countries:countries_view') urls.py path('', CountryListView.as_view(),name='countries_view'), path('countries/<pk>/', CountryDetailView.as_view(), name='country-detail'), … -
Django Migrations not updating Heroku PostgreSQL database
I've been stuck on an issue for a while where I have a model that I've created locally (class User(AbstractUser)), ran "python manage.py makemigrations" and "python manage.py migrate", which also works and interacts correctly with the django server when run locally. When I push this to heroku however, I receive an error response to certain api requests which essentially say "relation "app_user" does not exist". I assumed this was because somehow the postgreSQL db didn't receive the migrations when the app was deployed to heroku. After logging into the db I noticed that it had a few other tables, including "auth_user" (I assume this is a default django table), but not "app_user". I have done "heroku run bash" and "python manage.py migrate" in an attempt to migrate the changes to the postgreSQL db, but this doesn't have any effect. I'm not sure if this will be useful but the postgreSQL server I'm using is the standard Heroku Postgres Hobby Dev add-on. My questions are: Should running "python manage.py migrate" on heroku update the postgreSQL database? If so, how does this work? Given that the migrations are all on heroku, how can I manually update the postgreSQL with the migrations? -
Django Add default value to model field having the value of another field
I want to add a field to my django model and I want its default value to be equal to the primarykey value (id), but I want it to apply to all already existing records in my database. class ModelB(models.Model): id= models.IntegerField() index = models.IntegerField(default=" i want something here to get id value") I found previous questions covering this but the answers only give a solution where you have to add a method that adds the value on save. In my case I want this value to be applied to previously saved records also. Please if you have an idea I'd appreciate your help, thanks. -
Django not saving ModelForm data
I've looked at other questions but I can't find the root of my problem. I'm making a checkout view which should save an address with a customer.

How to configure the Index.fcgi path?
I'm finishing with setting up my Django project on my hosting using ssh. i am following an article to be able to install it correctly. Some of the steps I had to follow are as follows: Create the . htaccess file with the settings of the FCGI Handler and redirection to the index.fcgi file that will be created: AddHandler fcgid-script .fcgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.fcgi/$1 [QSA,L] and Create the index.fcgi file in the root of your application with the following content: #!/home/CONTA/.virtualenv/bin/python import os, sys from flup.server.fcgi import WSGIServer from django.core.wsgi import get_wsgi_application sys.path.insert(0, "/home/CUENTA/mydjango") os.environ['DJANGO_SETTINGS_MODULE'] = "mydjango.settings" WSGIServer(get_wsgi_application()).run() Already having those two files in the public html and opting the permissions to the index.fcgi using chmod 0755 At the time of me see if it is running using the following command ./index.fcgi, tells me that there is no file or directory. Which leads me to assume that I need to set a path within the index.fcgi or . htaccess but I do not know what I need to change since in the article only comes that. Thank you -

Django: How to clean a model with inlines?
