How to save file in two different directories after uploading a file in Django

Django JavaScript Array
I have the following JS code: data: [40, 60, 30, 65, 60, 95, 90, 100, 96, 120, 105, 134] This represents a curve in a graph on HTML. I want to draw a line (same value 12 times), and this value is brought by Django. The value is 100. I tried the following: in Django: limit = [mylimit for i in range(1,12)] in JS: data: {{ limit }} didn't work. I even tried creating the list manually on Django: limit = f"{limit}, {limit}, ...." and doing this on JS: data: [{{ limit }}] and nothing works. My goal is to take whatever limit I have (aka: 100), and have the following JavaScript: data: [100, 100, 100..... -

generating tokens and sending them to users
I am trying to implement the account activation and password reset functionalities and I would like to review the theory. I currently have 2 tables, user and token table. The user signs up. I save the user in the db, generate token and send it via email. So here's how I am tackling the problem: I am creating a 16bytes token and using this to create the link e.ghttp://localhost:1200/api/activation/<token>. However, in the db I am storing the hashed token (hashed with sha256). Then, theoretically, when the user clicks on the link, I perform sha256 on the token and see if it matches with the one stored in the database, right? I think the reason it is recommended to store the hash inside the db is because if the attacker has access to the db, he cannot impersonate the user (it still needs the original token), right? -

Custom django permissions for group chats?
I have a custom group model like this: class MyGroup(models.Model): name = models.CharField(max_length=200,null=True,blank=False,default="Group name") members = models.ManyToManyField(get_user_model(), blank=True, related_name="grpmembers") created_by = models.ForeignKey(get_user_model(), on_delete=models.DO_NOTHING, null=True, blank=False, related_name="createdby+") created_at = models.DateTimeField(editable=False) It works, it's fine, I override the save method in django admin so the created_by will point to the logged in user on save. Problem #1 Even if you are the creator of the group, you can select yourself to either be in- or be removed from the group which kinda looks silly. I'm thinking of solving this by saying the user can view the group if they're in members or created_by. Problem #2 Custom permission. I want to have some permissions, like: Can view the group: which means the user is either the creator or is in the members list Can edit the group: which means the user is the creator(can edit their own) or is staff(can edit anyone's stuff) or is superuser(root) I can write it down and imagine how it would work, but I have no idea how to implement these. I've found some ways, like creating a Meta and defining permissions there and also making the permissions as def(/functions), but how could I access the currently logged … -
