trouble showing desired checkbox validation state w/ bootstrap5 for django model form w/ m2m field and checkboxselectmultiple widget
I have a checkboxselectmultiple on an m2m model field in an ModelForm that is required - meaning at least one of the choices must be selected. I am using the boostrap5 was-validated class on my form: <form method="POST" action="{{ request.path }}" {% if attempt_submit %}class="was-validated"{% endif %}> This question is about how the validation shows up on my form with bootstrap5. Should be red border and red ! if not validated, green border and checkmark if so. However, for my checkboxes, if I don't have any selected (and everything else on the form validates), the form will show each checkbox option as green instead of red. Yet, it does know that it's invalid because the page focus will come back up the checkbox area to show the user what to correct (and it doesn't pass form.is_valid() in views.py. Why are these labels and boxes still showing green and how can I show them as red until I select one and it's now valid? Along the lines of this post, I have tried adding {% if form.sales_location.field.required %}required{% else %}form.sales_location.field.required=""{% endif %} to the checkbox <input>, but then each field is required and if I select one, the other remaining options … -

How to fill form fields since HTML
I have been looking for information on the web about how set values in forms of django but it has been really difficult. I need to put "Inicio" in the field "Origen_del_Circuito" after pushing the button, I have this code: Forms.py class CargaElectricaForm(forms.Form): Circuito=forms.CharField(label='Circuito', max_length=200) Origen_del_Circuito=forms.CharField(label='Origen del Circuito', max_length=200 ) views.py def bajatension(request): if request.method=="POST": form=CargaElectricaForm(request.POST) if form.is_valid(): #form.save() c="Inicio" return render (request, 'SizingWires/lowvoltage.html',{'form':form,'c':c}) else: form=CargaElectricaForm() return render (request, 'SizingWires/lowvoltage.html',{'form':form})** lowvoltage.html <form method="post" > {% csrf_token %} <table> {{form.as_table}} </table> <input type="submit"> Calculator</button> <input type="text" value="{{c}}"> </form> It doesn't work because it creates a new input and I need to use the field "Origen_del_Circuito". How can I access to the fields of my form since HTML (file lowvoltage.html) to put the value of "c"? I know the method "initial" however I need to put the value after of pushing the button. -
Where can I deposit PayPal funds?
I'm developing an iOS application that allows the user to purchase coins with In-App Purchase and send them to other users. Users who receive coins can withdraw them (receive real money) by entering their PayPal email. I will associate my PayPal account as a system to receive the receipts from the App Store and I will use the PayPal Payouts API (connected to the same PayPal account that receives moneys) in a Django backend to allow withdrawals. Since PayPal is not a bank, I need a place to deposit money that could then be withdrawn fast without limits. The problem is that since I don't know how many users I will have I can't use a regular bank account/credit card since they have a limit in the number of transactions per day/week/month. I know there are services like Stripe but I wouldn't know how to integrate them with In-App Purchase and withdraws. Any advice on where/how to deposit money maybe through some service? -
How can I use Validator in perform_create to limit image upload size for Django Rest Framework?

I am working with Django and trying to create two forms on one page which I am struggling with. It is for a simple online store, which needs a shipping and payment section on the checkout page.

I'm trying to do a CRUD with Python, and the data display is having a conflict between the tables
Ok, before anything I just want to make clear that english is not my first language and I've never posted a question here before, so I apologise beforehand if this all seems confusing, I'll try to be as direct and clear as possible here. I don't know what else to do at this point since I don't know anyone that deals with similar code, so I'm hoping someone here can maybe identify what I'm doing wrong here. T^T Basically, I'm doing this college assignment where I have to make a CRUD in Python for a motorcycle dealership (in my case I'm doing it with the django library, and using SQLite to manage the database). Everything is going well, except for the part where it displays the data (it's basically creating link to page on a local server on the computer. I'm not exactly sure how to describe it), and in the main page it displays a few tables, with data from the database tables (I have two, right now, one for client data and the other for the motorcycles). Problem is: the data input works just fine, but whenever I try to make the page display the data from the … -

Auto reloading no longer working after Django 1.11 to 3.2 upgrade
After upgrading an old inherited codebase from Django 1.11 to 3.2.13, I've found that Django no longer automatically reloads the server whenever a file change occurs. I've looked at the logger and it does say the the reloader is watching for file changes. After performing one change in the codebase and hitting save, the logger does say that it has detected a file change; however, nothing actually happens and the changes aren't reflected anywhere until you manually restart the server. If I make any further changes, there are no further logger messages displayed about file changes. I've also noticed that any version of Django before 2.2 seems to work in terms of reloading properly. It was only after upgrading to 2.2 and 3.2 that I noticed any issues. Here is a snippet from the logs. Staring threads ['manage.py', 'runserver'] System check identified no issues (0 silenced).

How to use bootstrap with xhtml2pdf?
I need to render PDF files dynamically in a Django web app. I understand there are 2 options : Render an html template file then convert it to a PDF file. I used xhtml2pdf Python library. The issue is that the template I want to use has bootstrap and it isn't supported by xhtml2pdf. Actually no javascript is supported and the generated PDFs are horrible. I have to write the html / css myself which I don't want to. How to solve this problem ? Is there an alternative library ? Convert a webpage into a PDF file directly -
How to login into a django backend in jest tests?
I have a django server that is running the graphQL backend. I need to authenticate a user so I can test against the /graphql endpoint. I have search and tried all the solutions for logging in. I keep getting status code 200 but if I read the html I am still on the login screen. If I subsequently try to hit the graphql endpoint I get a message that I need to be logged in to do it. I tried using withCredentials but it says that is not allowed. I have disabled CSRF for login for so that is not the issue. Any idea what is wrong with this code since it does not login and keep the session? import axios from 'axios'; import {wrapper} from 'axios-cookiejar-support'; import {CookieJar} from 'tough-cookie'; let f = new FormData() f.append('username','admin') f.append('password','password') const jar = new CookieJar(); const client = wrapper(axios.create({jar})); let login_resp = await client.post('http://localhost:3031/admin/login', f,{headers: {'Content-Type': 'application/json'}}); console.log(login_resp.status) console.log(login_resp.data) -
Django DateField validators are not running
I have a DateField as part of a form. date = forms.DateField( required=True, input_formats=[DATE_INPUT_FORMATS] ) When I view the form, on the front end, and I enter garbage in to the date field, Django doesn't throw a forms.ValidationError, and instead proceeds to execute the forms clean() method. I have tried adding my own custom validation method to the DateField: def validate_date_field(dateval): raise forms.ValidationError("date error...") date = forms.DateField( required=True, input_formats=[DATE_INPUT_FORMATS], validators=[validate_date_field] ) Even when my validate_date_field function is set up to always return a validation error, it does not execute. Instead, and again, Django proceeds to execute the code in the forms clean() method... What's going on ? -
