Styling PhoneNumberPrefixWidget in django with crispyforms
I'm rendering a crispy form and I've added a PhoneNumberPrefixWidget from this library, after adding it to crispy form's layout I can't change the style. Is there any way to achieve this? The library owns almost any documentation. My model: class Contact(BaseModel): person_phone_number = PhoneNumberField( verbose_name="Número de teléfono", null=True, blank=True ) Form: class ContactForm(BaseForm): person_phone_number = PhoneNumberField( widget=PhoneNumberPrefixWidget(initial="IN"), label=('Número de Teléfono'), ) class Meta: model = Contact exclude = [] Layout: self.layout.fields.append( self.make_row( [ "person_phone_number", ], size=6, ) ) -
How to setup "Hybrid Architecture" in Django while using Svelte.js?
I was trying to setup a svelte js in django to build an ecommerce website. Then, I found out there are 3 architecture : Server-First Architecture :bits of js scattered throughout django templates and static files. Client-First Architecture: Front end is a single page app that treats Django as an REST API Hybrid Architecture: It is a combination of both (client and server)-First Architecture. I choose Hybrid Architecture because I don`t want to wrestling with CORS or any 3rd party framework and having disadvantage of not taking advantage of using js tooling. Now the questions are: How do I setup Hybrid Architecture so that I can use Django Features alongside with Svelte js Features ? Can I setup Single Page App using Hybrid Architecture in Django? Is Single Page App good for Ecommerce in Django Note: I don`t want to use any Django libs such as Django-Svelte etc to setup it . I just want to install and setup with npm and webpack inside django just like normal setups. -
Django email logging isn't sending emails
I've implemented logging within my settings file, but no emails are being sent when a 500 error is hit. I'm on django 3.x All of the email settings within my settings file work. These settings are successfully used to deliver account confirmation emails, for example. EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'support@########' EMAIL_HOST_PASSWORD = '#######' DEFAULT_FROM_EMAIL = 'support@######' SERVER_EMAIL = 'support@########' EMAIL_PORT = ##### EMAIL_USE_TLS = True LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'mail_admins': { 'level': 'ERROR', 'class': 'django.utils.log.AdminEmailHandler' }, }, 'loggers': { 'django.request': { 'handlers': ['mail_admins'], 'level': 'ERROR', 'propagate': False, }, } } Thanks! -
django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 3072 bytes')
I am getting this error when migrating: django.db.utils.OperationalError: (1071, 'Specified key was too long; max key length is 3072 bytes') My configuration: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'myname', 'USER': '', 'PASSWORD': '', 'HOST': 'localhost', 'PORT': '3306', 'CHARSET': 'utf8', } } This happened after adding indexes to my model: class MsTune(models.Model): class Meta: indexes = [ models.Index(fields=['name', 'title', 'alt_title', 'index_standard_1', 'index_standard_2', 'index_gore_1', 'index_gore_2', 'alt_index_gore_1', 'alt_index_gore_2', 'alt_index', 'alt_index_standard_1', 'alt_index_standard_2', 'bass', 'variations' ]), ] What can the reason be?

custom static files not loading in django project
I have a django project where I have kept all the static files in a project level static directory. I have included STATIC_URL = "/static/" STATIC_ROOT = os.path.join(BASE_DIR, 'static') in the settings.py. ALso I have added + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) to the urlpatterns in the project level urls.py. My issue is that some of the static files load whereas some do not. For. eg. I am using django_google_maps and the (example url) http://127.0.0.1:8000/static/django_google_maps/js/google-maps-admin.js loads right and the corresponding work is done. But when I try to load my custom js/css/any-static files, (example url http://127.0.0.1:8000/static/images/favicons/favicon.ico or ttp://127.0.0.1:8000/static/js/image-upload-script.js), they do not load and raise a django.views.static.serve error with 404 not found. They are right there in the directory though. I see that the static files used by third party packages are loading right but not my custom ones. What is it that I am missing? Do we require something else to load our custom js/css files?? And yes I have used {% load static %} in my template. -
Django | argon2-cffi not hashing from admin panel
I am using argon2-cffi to hash users' passwords, however when logging into the admin panel and creating a new user, the password is not being hashed, it stays as the raw password. How can i overwrite this configuration? Or, what could I implement to hash the accounts that have raw passwords? I tried what the answer of this question suggested but hasn't worked.

Updating a list within a class

URL pathfinder in Django - any workaround when it keeps redirecting me to main view?
Sorry for being an embarrassing noob, but I have managed to complete like 99% of the Django Girls tutorial only to realize that there is one essential function in my basic blog site that's not working - the post titles on the main view don't link to their respective post views, even though the code seems alright to me...

Django REST Filter Nested Objects
I have a Student model which has a Many-To-Many relationship with an Assignments model. The Assignments model has a foreign key relationship with a Scores model.

Python Django Projects scaffolding boilerplate automation
I have django-cms project and i will use it as boilerplate, like when i got a project, i just run a command, it should generate initial setup/copy existing project with different name and changing some contenxt. For example, i have wsgi.py file """ WSGI config for mysite project. It exposes the WSGI callable as a module-level variable named ``application``.

Django integration with a python script
I have a python script that open and mantein a websocket (socket.io) with a remote server and a django instance. For my purpose I want the script to start and stop with the django server. I would also like to exchange data between the two. In praticular django needs to be notified whenever the remote server goes offline and keep this information globally. The tricky points for me are: Start and stop django and the script at the same time. Store globally the state of the script in the django application Is there a good way to implement this? -
How should I structure my database entities with invites and recipients for e-signing web app in Django?
I am interested in implementing the following requirements for my e-signature web application. A user can create a new signing contract. That contract can include multiple users to sign. The contract creator needs to provide emails of the recipients. Every recipient will have additional data assigned, like signing details, instructions and etc. However, the invited user can still be not present in the system. This is the trickest part. Right now my following implementation is the following: I create a contract, then check if a user is present in the system by making a filter by email. If the user exists, I create a many-to-many entity ContractRecipientEvent using through intermediate table with additional data, which is assigned to the contract. I create it many-to-many because the same user can be assigned to multiple contracts. If the user is not present I create the Invitation model, set all recipient's specific data, and send an email. Then the user is registered, I run the query of all Invitations records with that email and create ContractRecipientEvent, by copying data from the Invitation model. What I don't like with my approach are the following things: Many-to-many field. I would like to just use plain … -

Saving Queryset data to a model from a slider
I am trying to make a tinder like app where a hiring manager can search for specific IT candidates and then like or dislike them based on their qualifications. This app is acting as a frontend for an IT staffing company and uses their ZOHO database without showing any sensitive information for the candidates. Basically, the app calls the ZOHO API, fills the candidate model with data and I have a search form that uses a Queryset to display that data. I was able to put that data into a bootstrap carousel and scroll through each candidate but now I want to make a like button that will save a candidate to whatever user is currently logged in. I made a model for this called "UserChoice" but now I am unsure how to get the Queryset data into the new model and how to tie the button to each candidate the user wants to save. Currently, the buttons on the carousel just slide to the next candidate. Any help would be appreciated I am still pretty new to Django development. views.py(match app) number_of_candidates = len(database["response"]["result"]["Candidates"]["row"]) for P in range(0, number_of_candidates): #Clean slate for a new candidate. candidate_Pkey = "" candidate_Fname … -

Can I install PostgreSQL & PostGIS AFTER installing Django & GeoDjango?
I started following this tutorial2 after I failed with this one, tutorial1. I am trying to build this: Django is running after Django & GeoDjango installation. I am cautiously optimistic that I may have successfully installed GDAL v3.2.2, GEOS, and PROJ (worried that it is NOT PROJ.4). Next, I need to install PostgreSQL and its PostGIS extension. However, a lot of the instructions online warn that sequence of installation is important. I'm afraid to install PostgreSQL because I think it will break. This is the farthest I have gotten with the installation thus far and am afraid that I am building a house of cards that can fall at any time (due to my own lack of understanding). Do I proceed? Or should I just start over again from the start with a PostgreSQL installation and build fresh from there? Having learned that most of the trouble stems from those GIS packages, there is hope that I could now succeed. Hope is tenuous. Maybe I could just abandon PostgreSQL and run SQLite (except that appears to also require PROJ.4). The specs here say that I need PROJ4 (not PROJ) to work with PostgreSQL. But, PROJ might be the newer version … -
Django category model used in multiple models (belongs_to)
I have one Category model that I'd like to use in other models instead of creating different models for each case. Each model (Page, Article,...) has its own set of categories. Ex. Category model Page model with belongs_to category (page cat 1, page cat 2) Article model with belongs_to category (article cat 1, article cat 2) I can't use a polymorphic relationship since I don't have to store the id. So how can I represent that in my models? -

Django custom login form will not validate against is_valid()

I have been able to confirm the email & password values are being passed through to views.py as print(request.POST.get('') returns both the email (required for login) and the password.

Adding django-modeltranslation to existing project ruins tests
I have existing project and I decided to add translations options.
