Oh I see the problem. You are not passing an argument. It is basically blank. Ur not passing any integer value to the URL and it's expecting u to pass an integer value

Yeah
Bernard Kwey
so i should remove the "int:" since i don't won't to pass in any number
Bernard Kwey
or what
Anonymous
so i should remove the "int:" since i don't won't to pass in any number
If u don't want to pass any number then remove the int. What is this implementation for ? Is it for updating any value or for implementing a detail view ?
Bernard Kwey
for updating any value
Anonymous
for updating any value
Then u need to pass an integer value, otherwise we wouldn't be able to pinpoint which value to update
Bernard Kwey
that is why i pass in an id
Anonymous
I went through ur code and it feels like it is used to create a new entry.. not updating it right ? If that is the case, then no need for int..
Bernard Kwey
sorry i forget to tell you that
Bernard Kwey
so you can only make a new entry only when you click on a topic or when you create one...

Hello! Help me) I use pytest django, and i need load fixtures for each module. After the tests ended in the module, data must be deleted. How can i realize this??
Antony
so, i create in each app file
conftest.py
, and use this:
@pytest.fixture()
def django_db_setup(django_db_setup, django_db_blocker):
with django_db_blocker.unblock():
call_command('loaddata', './apps/accounts/fixtures/accounts.json')
call_command('loaddata', './apps/activation/fixtures/activation.json')
call_command('loaddata', './apps/questionnaire/fixtures/questionnaire.json')

I'm scratching my head trying to figure out how to migrate from Django 1.9.x to 1.10.x
from line 13 onwards the uhh.. some things in urls.py aren't imported, and that fails in Django 1.10, but I can't figure out how to rewrite this
view must be a callable or a list/tuple in the case of include().
as a note this was encased in patterns() before, which I removed and used [] instead

Alright so I correctly migrated away from patterns() but still stuck on figuring out how to deal with the other deprecation

have you tried using just assign_user_to_group() (as a function call) instead of that long "string" format?
because as I can see, those views are inside manager.views too (that you've already imported), am I right?

if I do that I just get name 'assign_user_to_group' is not defined
those views are not in manager.views from what I can see

Martin
I couldn't find "assign_user_to_group" in the entire project, the thing that's used is the name

Martin
and the name value is only present once in a template
Martin
$.post("{% url "master_assign_user_action" %}",
{
"assign": post_assign,
"perm": perm,
"email": user,
"group": group,
"csrfmiddlewaretoken": "{{ csrf_token }}"
}, function(data){
console.log("User assigned");
console.log(data);
}
);
}

I'm pretty sure I know the answer to this but does prepopulated_fields work if I exclude the field ? 🤣, or do i have to override the save method and slugify manually before save ?

Django would just throw an empty string

But I can't just install 2.3 and deal with 15 deprecations at once :D

sorry i cant help in javascript but adding forms but you can google om how to use a formset to add multiple forms dynamically you may find a simpler solution

When do you need to slugify ?
When I save, its just for pretty urls. So I was contemplating hiding them from the users in the admin panel. Now I use prepopulated_fields to autofill the field while they type the name.

Just branch out and start working.... If not youll be doing alot more work all together.

pre_save signal could help you to slugify on hitting save
