Re: SMTP Authentification error

In my experience, Gmail does not allow (or does not support) using it as a smarthost if all you have is a free account, and even if you get it to work it will eventually cause you headaches. I don't know if this has changed the last few years, but I feel it hasn't. It's much better to use another service. I use runbox.com; mailbox.org is another solution. These are both paid email services. In a recent thread, someone also mentioned mailgun and sendgrid, which may be better suited for this purpose.

Other than that, you should enter a breakpoint or something in your code to verify that the values of EMAIL_HOST_USER and EMAIL_HOST_PASSWORD are what they should.

Antonis

I included the 16 character code to my environment variable and called it in my settings.pymfile,  but still the error occurs. Also here is my settings.py file:

You probably want to create a custom database router[1].

I'm assuming the view you're having problems with is manageStock3. You
probably want to filter stocks based on the pharmacist that is logged in. Try
something like:

stocks = Stock.objects.filter(pharmacist_id=request.user)

You were not the one I was replying to so I don't understand why you are
replying like you were advertising this.

Harsh Jain has previously been spamming this mailing list and he's the
one I was replying to.

Re: Calculated Fields

As was found out with the conversation with Mike Dewhirst, the error appears to be because of wrong understanding of operator precedence. That's easy to correct with parentheses.

Except for that, I wouldn't do it that way; I wouldn't store the total price in the database, because it's likely to create problems. Models that have not (yet) been saved to the database will not have a total price. Models that have been loaded from the database, modified, but not (yet) updated in the database will have a wrong total price. Saving to the database with bulk operations or with plain SQL may result in no total price. These are all symptoms of storing redundant information in the database, which is something that should be avoided.

Instead, I would do this:

class Stock(models.Model):
    unit_price = models.DecimalField(max_digits=10, decimal_places=2, default='0', blank=True, null=True)
    quantity = models.IntegerField(default='0', blank=True, null=True)
    reorder_level = models.IntegerField(default='0', blank=True, null=True)

    @property

    def total_price(self):

        return (self.quantity + self.reorder_level) * self.unit_price
