remember, templates are not meant to hold logic, templates should be as dumb as possible, make your logic in the views

Try wagtail

Django CMS is good too

You'll want window functions. See an example here: http://sqlfiddle.com/#!15/9fd7a/8 Django 2.0 supports Lag() and Lead() https://docs.djangoproject.com/en/2.0/ref/models/database-functions/#window-functions

Nevermind, I'm just kidding

Im using Django 2.2, Im having a problem of using the "login_required" decorator. I want my user who is trying to enter a view/url to go back again to my login page if he/she is not authenticated. .

Im getting the 404 page error, what I want is to redirect my user to my login page if he/she is not login/authenticated. ..

do I have to create a middleware or login_required decorator will do?. .

login_required is enough

How can I redirect it to my login page?. . I tried to use this "/accounts/login/" but Im getting the 404 error. .

hey guys, i need your help i have two models like so: class Stock(models.Model): stock_name = models.CharField() stock_quantity = models.IntegerField() class Orders(models.Model): order_name = models.ForeignKey(Stock) order_quantity = models.IntegerField() First off i fill in the Stock and then i have to add orders which are based on stock model when i add order, i choose stock_name from Orders model and enter order_quantity the thing i want to do is when i save Order with order_quantity it would automatically subtract it from a stock_quantity on save how can i make it?

def save(self, *args, **kwargs): self.order_name.stock_quantity -= self.order_quantity super(Order, self).save(*args, **kwargs) i made this one , but it's not working

that's what i'm doing rigth now thanks

that's what i'm doing rigth now thanks

and one more question how to raise an error message if stock_quantity is less than order_quantity?

p.s. i've already made a post_save signal

I'd rather use a form to validate the model before it's saved.

can you explain more pls?

Check out official docs: https://docs.djangoproject.com/en/2.2/topics/forms/#building-a-form Basically you create a form class which validates the data before saving the model. You can add custom validation rules by overriding clean_<field>() and clean() methods

There is definitely a tag <form> ... </ form> ?

ModelForm have many fileds, Ones are fields that we see, Ones are error fileds that you dont see them When i render form like {{form}} the UI is unacceptable How can i modify it and access all fileds one by one? like form.nameInput

how to do url mysite.com/articles/?tagid=12 ?

with the keyboard? 🤔

sorry i didn't understand your question
