I'm developing a project that is quiz. In models i have a class Quiz with a field code, and to prevent a problems with a quizzes's codes, i created a class Code. How can i check that code is available?
Д
Bought
It's like in Kahoot.
Bought
Users use code to join a game.
Bought
one-to-one
Д
so there can be precisely one code per one quiz always
Д
if I know the code, there is a quiz waiting. if I start a quiz, I will have a code
Bought
It's not safe
Д
but that's what your Data Model suggests
Д
we don't care how you use it yet, whether there is logins etc. or not
Д
but there is probably so that if I have the code "UWU-ROLLOTASTIC" and that takes me to a My Little Pony -quiz, once that's Done, then I can use the "UWU-ROLLOTASTIC" code again to go do some other Quiz
Д
but as long as the My Little Pony quiz is still there, UWU-ROLLOTASTIC <=> My Little Pony
Bought
There are only SIX digits in code
Д
doesn't matter. the same principle applies regardless
Д
okay so
Bought
Okay, thanks.
Д
I'm trying to say this simply
Д
because for me this is already a solved problem but clearly we need to work
Д
you're going to need to make sure there is only one valid Code per Quiz
Д
sigh that's what you asked for didn't you
Bought
Ok, your idea is pretty cool
Д
you're going to need a relationship that binds together Quizzes and Codes
Д
then if a Quiz already has a code, or a code is already in use, then it can't be added to that relation again
Д
like, you pair them up on some kind of list
Д
then when the Quiz ends, you can delete that code, and that Quiz from that list
Д
but when somebody tries to start a new Quiz or use a new Code, you have to check against that list whether it's legal or not
Д
you can create a new Class for that
Д
something like class RunningQuiz
Enes
Д
@sanzh_py got it?
Bought
Yep, thanks
Д
only your RunningQuiz list does
Д
class RunningQuiz(model):
quiz = ForeignKey(Quiz)
code = ForeignKey(Code)
something like this
Д
if you really want the codes to be a Model (I don't know why they would need to be)

Have you installed django on your system??
Mallika kambala
No I don't know about it I have source code zip file
Vikash
No I don't know about it I have source code zip file
Extract zip file go to manage.py file directory and before this step if you have all ready install python than install django on your system
Vikash
Using pip install django in cmd
Vikash
if there is a requirments.txt file available then use pip install - r requirements.txt for download all dependency for regarding project

Hi everyone.
In model Quiz i have a field code, and in func "generate_code":
if code in instance.objects.all().values(code):
return generate_code(instance)
Is it correct? field code is a positive small integer field

How to write tests? I've seen this, but still don't know purpose of this
people often write tests "incorrectly" after the code exists but their biggest purpose is to help design; they have many purposes

from docx2pdf import convert

convert("django.docx")
# Converting docx specifying both the input

convert("django\GFG_1.docx", "Other_Folder\Mine.pdf")
# Notice that the output filename need not be
# the same as the docx
# Bulk Conversion

tests are normal classes\functions but they contain Assertions. they are basically if-clauses that check that something is True. if it's not, they throw an Exception and then you get "this test failed!"

I think it's only work with Windows and mac os

python comes with a package called unittest which helps you write those test classes+functions. but because Django has something more involved, like the web stuff, Django defines its own unittest too

But, what will happen if i won't use tests(just use a runserver?)

nothing will happen. you won't be as good of a progammer :)

I use Linux
Libre office changes docx files to odt, you can reconvert it by simply changing the odt to .docx

Ok, gonna learn tests
testing is theoretically easy but it requires a lot of experience so that's why I'm telling you to start practicing
Bought
Can you recommend where i can learn tests, thanks
Bought
I will find some good video to get you motivated :)
Ohhh, thanks again. You're such a good person

While running command:
heroku run python manage.py migrate
Getting following error:
SECRET_KEY not found. Declare it as envvar or define a default value.
(Using python-decouple to get SECRET_KEY and it worked in localhost but after deploying it to Heroku getting this.)
Any suggestion?

don't know about python-decouple or Heroku but you need to get the SECRET_KEY setup on Heroku too
