Toggle a boolean parameter for user

[pnizet]

Hello,
First thanks for this project which is really neat.
I'm a begginer and I'm trying to use unicorn for a single pupose (for now), the usecase if the following : "allow the user to enable or disable sending emails for his account by pressing one button"

I tried this :

from django_unicorn.components import UnicornView
from django.contrib.auth.models import User
from my_proj.models import user_conf


class MyprojtempchangesConfView(UnicornView):
    allow_email = ''

    def change_email_conf(self, user_id:int):      
        user = User.objects.get(id = user_id)
        if user_conf.objects.filter(user = user).exists():
            allow_email=user_conf.objects.filter(user = user)[0].allow_email
            user_conf.objects.filter(user = user).update(allow_email=not(allow_email))
        else:
            user_conf.objects.get_or_create(user = user, defaults={'allow_email': True})

and this

<div>
    <div unicorn:key="boolean-toggles-key">
        <p>Changements Temporaires</p>
        {% if allow_email %}envoi mail autorisé ✅{% else %}envoi mail refusés ❎{% endif %}        
        <button unicorn:click="change_email_conf({{request.user.id}}) ">On / OFF</button><br />
    </div>
</div>

but nothing happens...
My request is cached

What is wrong ??

an answer to myself :

class MyprojtempchangesConfView(UnicornView):
    user = User.objects.get(id = 1)  #not sure about this... not really clean
       
    def change_email_conf(self, user_id:int):      
        self.user = User.objects.get(id = user_id)
        if user_conf.objects.filter(user = self.user).exists():      
            user_conf.objects.filter(user = self.user).update(allow_email=not(self.allow_email))
        else:
            user_conf.objects.get_or_create(user = self.user, defaults={'allow_email': True})

just a small hint: use user = User.objects.none() as class attribute. You don't need to initiate it at creation of the component.
If you want to load a user at page load, use the mount() method and load it there.

and now, I want to init with the database value, I triedto use the mount() method with an argument (but it is not the correct way to do it)

I tried this (see below) to initiate allow_email with the database value, but I can't give mount user_id, how to do so ?

    def mount(self, user_id:int):
        self.user = User.objects.get(id = user_id)
        self.allow_email=user_conf.objects.filter(user = self.user)[0].allow_email   

[pnizet]

init is meant to 😄

    def __init__(self, *args, **kwargs):
        super().__init__(**kwargs)  # calling super is required
        self.user = kwargs.get("user_id")
        self.allow_email=user_conf.objects.get(user = self.user).allow_email

@pnizet Sorry, just catching up here... did you get this working? It looks like maybe, but I'm just double-checking. :)

yep it works !
