How to find how many objects reference the same foreign key in Django
I'm creating a simple web app that uses Django as its backend. Currently, I have two models: Toy and Attributes. A toy contains a reference to an attribute. My goal is to return an error to the frontend whenever an attribute is going to be deleted but is still referenced by a toy. For example, a train toy could have the attribute "black". When I go to delete black, I should get a not possible error, since "black" is still referenced by the toy train. How would I go about checking the number of references an Attribute has? -

define fields of Django ModelForm class on instantiation
I want my website-users to quickly adjust just one attribute of my model objects in a view (with htmx) (to avoid creating tons of ModelForms just with other fields attributes) that's why I want to create a ModelForm where I can define the displayed form fields on instantiation of the form in the view function, the desired field will be passed as a 'fieldlist' parameter into the view function , somehow like that: class ModelForm(ModelForm): class Meta: model = Model fields = --> how to put the at the ModelForm-instantiation (with a request passed) "fieldlist" parameter here? def __init__(self, *args, **kwargs): fieldlist = kwargs.pop('fieldlist') super(ModelForm, self).__init__(*args, **kwargs) any hints? -
How to send Crypto payments (programmatically) gotten through coinbase commerce
i have successfully integrated coinbase commerce into my django app for receiving cryptocurrency payment from the users. However the site payment process involves receiving payment from a User A which is intended for User B into the site coinbase commerce wallet and then only after User B has completely handed over whatever was the value/asset been paid for, then the payment would go on to be forwarded finally to User B. But the issue is that coinbase commerce has no facility for sending payments. and though payment can be sent with a python api on COINBASE, they are two seperate things and the money/coin in coinbase commerce would not be accessible from COINBASE even if it the same user/profile on the platform. Please does anyone have a solution to this problem...even if it does not use coinbase commerce, the only requirement is that it uses a crypto payment gateway -
Ajax / Django / jQuery - autocomplete titles and remove when user deletes what was typed into input
(Reposted from Reddit) I am in the early stages of generating an autocomplete (I would love for it to be a drop-down from the input I'm using, right now it's divs that are being prepended), when a user begins typing (once >2 characters reached). I had a version that would somewhat-correctly show these results that it's pulling from a massive database after typing into the input has begun. But when I added the "else if" close to the bottom with the intention of removing all divs that have been added once the user starts deleting the typed-in phrase, nothing is coming up now. This is the implementation of my js file as it currently stands: $(document).ready(function() { $( "#movie_titles" ).keyup(function(){ var movie_titles = $('#movie_titles').val(); var has_typed = false; if (movie_titles.length > 2) { $.ajax({ url: '/get_movies', type: 'POST', data: {'movie_titles': movie_titles, csrfmiddlewaretoken: '{{ csrf_token }}' }, dataType: 'json', success: function(response) { // var len = response.length; has_typed = true; $('#movie_titles').empty(); console.log(response) // for (var i = 0; i < len; i++) { $('#result-part').prepend('<div class="movie-title">' + response.title + '</div>'); // $(this).val(''); return false; } }); console.log(movie_titles); } else if (has_typed && movie_titles.length <= 2) { $('#result-part').remove(); } }); }); Any ideas … -
Django passwords changing by themselves
I have a really weird issue, I use django authentication and I use django AbstractUser. The problem is passwords are changing by themselves, I'm not even able to track when this change occurs, even if the App is not used, once I try to login again I can't it tells me the password is wrong, How did I know that the password changed ? I compared the SHA code in database, since I always use "admin" as password for the app. I have some password configs in my settings but I doubt it is linked to them : REST_AUTH_SERIALIZERS = { 'PASSWORD_RESET_SERIALIZER': 'forms.api.serializers.PasswordResetSerializer', } # Password validation AUTH_PASSWORD_VALIDATORS = [ { 'NAME': 'django.contrib.auth.password_validation.UserAttributeSimilarityValidator', }, { 'NAME': 'django.contrib.auth.password_validation.MinimumLengthValidator', }, { 'NAME': 'django.contrib.auth.password_validation.CommonPasswordValidator', }, { 'NAME': 'django.contrib.auth.password_validation.NumericPasswordValidator', }, ] this is my User model class User(AbstractUser): ''' model for user extends default django user ''' MALE = 1 FEMALE = 2 GENDER_CHOICES = ( (MALE,'Male'), (FEMALE,'Female') ) gender = models.PositiveIntegerField(choices=GENDER_CHOICES,null=True) email = models.CharField(max_length=256,unique=True,blank=True,null=True) receive_emails = models.BooleanField(default=True) objects = CustomUserManager() created_date = models.DateTimeField(auto_now_add=True, blank=True, null=True) updated_date = models.DateTimeField(auto_now=True, blank=True, null=True) Can you please, if anyone has encountered this issue before, let me know and also if there is a solution to solve this. … -

Hosting Static Files on AWS - Amazon Bucket - Django
I need to host my static files on AWS in order to sort out some problems I have been having with my Django website. I have been trying to solve this on and off for about a year now while finishing up the rest of the website but now it is the last thing to do and I can't put it off any longer. I have looked at the documentation and looked at so many videos with no luck. Below is everything I have including code and my bucket file configuration that pertains to this problem. Everything that I currently have running should be hosting all my static files on my Amazon Bucket, however, it isn't. I'm not getting an error but when I 'inspect' on google they are all being hosted locally. Thank You so much in advance. P.S. = The gallery folder I have in my bucket is for images that users upload and those images are successfully being hosted on AWS and working fine it's just the static.

Describe MS SQL database for Django legacy integration
I am trying to integrate a legacy DB (MS SQL 2012) into Django just to fetch data (no write operations). I have tried using the inspectdb management command but it only generates tables which don't have any foreign keys. I am fairly certain that the DB tables do not include foreign keys from a different DB (which is currently not supported by django). How do I go about getting all the attributes for each column/field in all of the tables so that I can create Django models on my own? Details that I'm looking for include (but are not limited to) : Column data type, All relational keys (Foreign, o2o, o2m), Max length, Max digits, Isblank, Isnull, Unique, Uniquetogether, Decimal places. -
How to post information from javascript TextInput into a django sqlite database?
I am completely new to website backends and am stumped on how to post information from a TextInput field created in Adobe Animate to a database. I would be able to do this no problem if the TextInput was part of an HTML form, but because it's javascript, I am lost. I've uploaded the project to my Github here: https://github.com/jeremyjed/SavetheDate and the site can be viewed on the repos page here: https://jeremyjed.github.io/SavetheDate/ I also have this page running on my local machine inside django. As you view that, the second to last slide has a TextInput labeled "addrs" and a submit button labeled "submit". Right now I have it so the animation continually loops on this slide to allow a user to input their data. Once the submit button is clicked the animation progresses to the last page. All I'm trying to do is to post the information populated in the TextInput field when the submit button is clicked and save it to django's database. I'm assuming this isn't too complicated, I just cant seem to get it to work. Any help would be really appreciated! -
Dj rest auth using JWT Token stored in HttpOnly cookies
I'm making a Django Rest Framework application with a JWT authentication with tokens stored in HttpOnly cookies. Authentication is performed via reading the access cookie. I'm using a dj-rest-auth library for this purpose, but I'm a little confused of the security aspect of such method. Knowing that having authentication data stored in cookies can be used to perform CSRF attack, how can one protect their web against such attacks for a specific case I've described above? All cookies are set to be SameSite=Lex. Do I need to also send X-CSRFTOKEN header obtained from the backend? That would mean that every request to the api will need to have that header. What should be the optimal setup having all those libraries? -
Django how to save value to model without being present on form post

I tried to add the following to my view under if fm.is_valid(): attempting to save username as current user to the … -

How to get data from config file (config.json) in real time in settings.py file in django
I have a project made in Django. I have only added social auth for login purposes. I want selected emails only to log in to the website. I used social-auth-app-django library for social auth and added a variable SOCIAL_AUTH_GOOGLE_OAUTH2_WHITELISTED_EMAILS to the settings.py file where it contains a list of all the emails permitted for logging in. My project directory looks something like this: project_parent/ ----project/ --------settings.py --------wsgi.py --------asgi.py --------urls.py ----app/ --------models.py --------views.py --------urls.py --------admin.py ----db.sqlite3 ----manage.py ----config.json Here is the config file: { "OAUTH2": { "WHITELISTED_EMAILS": [ "xyz@gmail.com", "abc@gmail.com", "efg@gmail.com", "lmn@gmail.com" ] } } In settings.py file I have loaded the config file like this: config = open('./config.json',) data = json.load(config) SOCIAL_AUTH_GOOGLE_OAUTH2_WHITELISTED_EMAILS = data['OAUTH2']['WHITELISTED_EMAILS'] I have made a webpage that takes the new mail id (need to add to the config file) and appends that particular mail id (or a list of mail ids) to the config.json file. But now the problem arises, the newly added mails don't reflect directly to the variable defined in the settings.py file. For that, I need to restart the code in order to get the latest config file. Every time I add a mail id, I need to restart the code. I thought to … -

Django code cannot install a pickled sklearn variable
