Re: 'Sandboxed' Template engine/context

2020-07-10 Thread Michael Thomas

Hi,

I'm aware that other template engines could be used, but it would be much 
more preferable to stick with Django's template engine for a variety of 
reasons (eg. using the same tags in the 'sandboxed' environment vs. 
regular).

Performance queries helps

2020-07-10 Thread carlos

Hi, i need any advice for performance queries
i have a model name Post
post have m2m categories and fk author

the index page show 7 categories in separated row
i try performance
this example
queryset_global =
Post.objects.filter(status__contains='publish').prefetch_related('category').select_related('author')
then i make 7 queries for 7 categories show in index page.

newscat1
= 
queryset_global.filter(category__slug__contains="cat1_name").order_by('-date')[:5]
newscat2
= 
queryset_global.filter(category__slug__contains="cat2_name").order_by('-date')[:5]
newscat3
= 
queryset_global.filter(category__slug__contains="cat3_name").order_by('-date')[:5]
newscat4
= 
queryset_global.filter(category__slug__contains="cat4_name").order_by('-date')[:5]
newscat5
= 
queryset_global.filter(category__slug__contains="cat5_name").order_by('-date')[:5]
newscat6
= 
queryset_global.filter(category__slug__contains="cat6_name").order_by('-date')[:5]
newscat7
= 
queryset_global.filter(category__slug__contains="cat7_name").order_by('-date')[:5]

i retrieve 35 post for show in index page

*according debug toolbar this produce SQL*
*2599.59 ms (44 queries including 34 duplicates )*

Why?

but when i loop in template index.html
{% for news1 in newscat1 %}
{{news.name}}
{{newa.date|date:'Y-m-d'}}
{{news.body|safe|truncatewords:20}}
{{news.category.all.0}}
   Read More
{% endfor %}
 ...
this repeat in the template 7 time
...
{% for news7 in newscat7 %}
{{news.name}}
{{newa.date|date:'Y-m-d'}}
{{news.body|safe|truncatewords:20}}
{{news.category.all.0}}
   Read More
{% endfor %}


*according debug toolbar this produce SQL*
*3463.65 ms (86 queries including 77 duplicates )*

this is incredible it doubles the amount of queries to the db that may be
happening?

i need some ideas or tips

Cheers

Limiting access to data through user permissions?

2020-07-10 Thread Will Meyers



Just need some help getting over a wall I've hit.

I have a web application that whenever a user signs up, is assigned a 
License. This License has CustomPermissions attached to it telling what 
values of a field within a materialized view they have access to. I have an 
API that needs to filter data requested against the User who requested it 
based on the User's license. I drafted some example models below that 
outlines my problem.

class CustomPermission(models.Model):
name = models.CharField(max_length=255)
field = models.CharField(max_length=255)
value = models.CharField(max_length=255)

class License(models.Model):
name = models.CharField(max_length=255)
permissions = models.ManyToManyField(CustomPermissions)
...

class User(AbstractBaseUser):
license = models.ForeignKey(License, on_delete=models.CASCADE)
...

This works fine if I'm only filtering columns with text values. I can just 
do

...
user = request.user
permissions = user.license.permissions.values_list('field', 'value')
return queryset.objects.filter(**{field: value for field, value in permissions})

This issue is that I cannot filter against other datatypes (datetimes for 
example). If I wanted to limit access to data published in the last 90 days 
for example, there's no way to represent that in this model.

To solve this I was thinking of using a sparse table for the 
CustomPermission model. Something like

class CustomPermission(models.Model):
name = models.CharField(max_length=255)
field = models.CharField(max_length=255)
operation = models.CharField(max_length='32')
text_value = models.CharField(max_length=255, null=True, blank=True)
date_value = models.DateField(null=True, blank=True)

Where operation would be equal to '__gt', '__lt', ... things like that. I 
can then just do something similar as before

...
user = request.user
permissions = user.license.permissions.values_list('field', 'operation', 
'text_value', 'date_value')return queryset.objects.filter(**{fld + op: txt_val 
or dat_val for fld, op, txt_val, dat_val in permissions})

But this does not feel right, and can get messy quickly. Any suggestions?

DB Router default issue

2020-07-10 Thread JJ Zolper



Hello, I am trying to prevent models in my api app from migrating into the 
default database but I'm confused about the router. It seems every time I run 
migrate even with the router it continues to migrate.



#apps.py

from django.apps import AppConfig

class ApiConfig(AppConfig):
name = 'api'
label = 'api'



#settings.py

DATABASE_ROUTERS = ['myproject.dev_db_router.APIRouter',]


DATABASES = {
'default': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'default.sqlite3'),
},
'mydb': {
'ENGINE': 'django.db.backends.sqlite3',
'NAME': os.path.join(BASE_DIR, 'mydb.sqlite3'),
},
}



#dev_db_router.py

class APIRouter:
"""
A router to control all database operations on models in the
api application.
"""
route_app_labels = {'api',}

def db_for_read(self, model, **hints):
"""
Attempts to read api models go to mydb.
"""
if model._meta.app_label in self.route_app_labels:
return 'mydb'
return False

def db_for_write(self, model, **hints):
"""
Attempts to write api models goes to mydb.
"""
if model._meta.app_label in self.route_app_labels:
return 'mydb'
return False

def allow_migrate(self, db, app_label, model_name=None, **hints):
"""
Make sure the api app only appears in the
'mydb' database.
"""
if app_label in self.route_app_labels:
return db == 'mydb'
return False


I've tried:

python manage.py migrate --database=default

python manage.py migrate


etc and every time it says:

  Applying api.0001_initial...* OK*


Even though I told it False if it does not meet the case of db == 'mydb'. I can 
specify 'mydb' and it says it works:

python manage.py migrate --database=mydb

but my concern is it always migrates into default even when I'm trying to tell 
it not to. In the future there will be models I do want to migrate into 
default, but not these in the api app. Based on the documentation I'm doing 
everything correctly.

What am I not understanding?

Thank you.

Best,

JJ

Re: Django ContentTypes required?

2020-07-10 Thread JJ Zolper

Dan,

Thank you so much. I was able to get it figured out after I smoothed out an 
issue with the database. My assumption is something with the database was 
causing it to throw this confusing and unrelated error. I changed the 
settings files around too but really did not change or remove anything that 
would have made a difference. Or should have. The app was not included, etc.

Best,

JJ

Re: note sharing

2020-07-10 Thread Kunal Solanke

If you don't want to do complicated things just add manytomany field for
sharewith in note model
And while user requests the notes page just make a query to database

Notes.objects.filter(Q(sharedwith=current_user ) l Q(author=currentuser))

And send this back to user



Imp-while creating a note user should specify whom to share with
You can use multiple input for that

Hello guys
Please anyone help me out I am not able to figure out the internal sharing

 Django website where users can privately create and share notes. All users 
will have an account and they will be able to signup then login to their 
account. Once logged in they will be able to write notes in the web app. 
While creating the note they will have the option to share the note with 
another user of the web app. The app will contain a page where the user can 
see the notes that they have created and the notes that have been shared 
with them. 

Thank you

Wrong use of the word "module" in the Documentation

2020-07-10 Thread Ivo Shipkaliev

Hi there.
I was reading Django Documentation, specifically Models page:
https://docs.djangoproject.com/en/3.0/topics/db/models/

Under "Using models" section, the second sentence reads:
"Do this by editing your settings file and changing the INSTALLED_APPS 
setting
to add the name of the module that contains your models.py."

Now, as "models.py" is a Python module, this statement is saying that you
should add the name of the module that contains the other module.
A Python module cannot contain a module. The word "module" here should be
replaced by "directory" or "package".

Do I need to change my normal Django code when introducing Django Channels?

2020-07-10 Thread Marlon Patrick

Hi guys, I'm new to the python world and consequently I'm new to Django,
Channels, WSGI, ASGI, etc.

I asked this question on StackOverflow but I still haven't had any answers,
so I decided to post here in order to try to receive some guidance.

https://stackoverflow.com/questions/62544489/do-i-need-to-change-my-normal-django-code-when-introducing-django-channels

I have a small backend application using Django + Django Rest Framework. My
code is very trivial, composed of the most common concepts in the
framework: views, serializers, models, urls, etc. In addition, I use a
relational database.

My environment is this:

- Python 3.8
- Django 3
- Django Rest Framework 3.11

Now, I need to add support for WebSockets and I did the basic configuration
described in the Django Channels tutorial. At the moment, I have not
configured any channel layers or created any WebSocket endpoint.

After these configurations the runserver is using an ASGI development
server and apparently my REST endpoints are all working.

Some questions:

Considering that all my code is synchronous, wouldn't it be necessary to
make any adjustments to it?
-

This configuration above, already does all the magic necessary for my
synchronous code to be executed safely in daphene considering that it is an
ASGI server?

Where exactly should care be taken regarding synchronous code?

Can I serve normal HTTP and WebSockets requests using only ASGI in a
reliable and stable manner? Or, is it recommended to serve HTTP traffic
using WSGI and leave only WebSockets traffic to daphene?

'Sandboxed' Template engine/context

2020-07-10 Thread Michael Thomas

Hi all,

Does anyone know of a straightforward way to create an independent template 
engine instance with a subset of the tags/filters/etc. defined?

The use-case is for allowing user-supplied template content, while 
preventing said users from being able to use features that could be 
dangerous, leak information, etc.. (Eg. {% extends %}, {% load %}, 
{{my-secret-variable-that-is-loaded-into-global-context}})

Kind Regards,
Michael
