Hello, I am still new to Django, so I apologize if this seems like a silly
question. I've not been able to find what I need on Google, StackOverflow,
or the Django Docs.
I am using Django 2.0.5.
I understand that the correct way to run startup code is to subclass
AppConfig and override
I'm looking for some best-practice (or at least workable) suggestions for
avoiding import-time queries. I have some database records that are
constant, and these constants are used all over the application. Is there
any way to get those constants out of the database once at startup?
At
I've been experimenting with it and it seems to be working pretty well.
Thank you, Julio!

Oh, this is perfect! Works exactly the way I need it. Thank you so much for
your help!

I have a legacy database that we want to replace, and Django is still new
to us. There are some 40,000 items in the old db, and each item has an
item_number that is not necessarily the primary key; that way, the users
can maintain their own sku number system and we can maintain data integrity
I would actually prefer to override clean(), but CreateView doesn't appear
to have a clean() method that I can override. I did make a ModelForm to use
with the CreateView, but the clean_item method I defined there never gets
called--breakpoints and print statements are all skipped, so I don't
Ah, thank you for the link; it put me on the right track, I think, with
custom validators.
As an example of why I need to customize the item fetching: I have an item
that has an item_number of '515874'. That number is how the users interact
with the item. However, the primary key for Item
I seem to be having trouble understanding some of how form validation
works, resulting in two problems.
I am trying to write a CreateView in which a user can type in an item
number, and the program will use that instead of the item's primary key to
perform the lookup.
The docs appear to
I have a CreateView in which I need to alter the user input. I may have
found a way to do so using get_form_kwargs, but I'm puzzled by a couple of
things:
I know that kwargs['data'] is a QueryDict, which is immutable. So I tried
the doc's QueryDict.copy() recommendation:

Hello, I'm simplifying a previous post. I just started using Django a few
months ago, and for some reason I'm still having trouble getting my mind
around the way Django thinks about some things.
I have a test class that contains two specific tests that always pass when
run just by themselves,
It's a script that's supposed to run in the background for an inventory
management program. The basic idea is that it periodically collects Order
objects that are associated with a particular Status (1-M foreign key,
though more like 1-1 in practice). Orders have one or many Orderlines. Then
Hi Melvyn,
I've been working on getting permission to post the code, but everybody who
can do that is on vacation at present, unfortunately. I'm hoping somebody
will be back to work on Monday. I did try the test --parallel 1, but that
didn't help.
The problem tests all cover a particular
I'm looking for a way to redirect to a different page depending upon which
submit button the user clicks. I included a formaction tag in the template,
but django still demands that get_absolute_url be defined. Using Django 2.0
Basically, I'm trying to write a small app that launches a test

app_name = "utils"

Thank you for the clear explanation! It works beautifully now.

Hello, I'm looking for some insight for some odd behavior with some unit
tests, which I think stems from some misunderstanding of how these classes
actually work.
1. For TestCase, the Django docs say that it does matter what order in
which the tests are run. But elsewhere in the same doc, it
I have an Item model. It has both a primary key and an item number; the
users refer to item numbers when finding things, and the actual primary key
is not exposed. I'm trying to write a CreateView that will allow the user
to input the item number.
I see that CreateView defaults to using the
I need to render some form fields by hand in order to meet style
requirements. I am using UpdateView instead of a ModelForm since I just
need a couple of foreign key fields that are already defined on the model,
and I am using html elements to prevent invalid data from being
entered.
