Tutorial Problems...

[Emil Lilja]

Hey all,

I realize I'm somewhat of a buffoon on the subject but I've tried learning Python on my free time the past couple months and want to get in to Django. 
So after following the tutorial and trying to launch the server with: python mange.py runserver all i get is Watching for files with StatReloader and it never moves in from there unless i terminate with ctrl+c. Feels like I'm missing something fundamental, can anyone shed some light?

In my opinion that confirms you are not a buffoon but rather you are
strategically right on the money.

Have you tried launching a browser and visiting http://localhost:8000/

Hey,

Thanks for your reply!

So yeah i did the tutorial from scratch again and noticed like you were aiming at that the server was actually running. Even though the tutorial clearly states that you should get the following output when running runserver, I only seem to get this after i terminate with Ctrl+C:

Performing system checks...

System check identified no issues (0 silenced).

You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

Django version 2.2, using settings 'mysite.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.

Anyways i realised why the server probably isn't running, I've created the polls app and followed all the steps (copied code exactly) and i get a SyntaxError?
What's causing this?

$ python manage.py runserver Watching for file changes with StatReloader ### I Press Ctrl+C and get the following output: Exception in thread django-main-thread: Traceback (most recent call last): File "C:\Anaconda3\lib\threading.py", line 917, in _bootstrap_inner self.run() File "C:\Anaconda3\lib\threading.py", line 865, in run self._target(*self._args, **self._kwargs) File "C:\Anaconda3\lib\site-packages\django\utils\autoreload.py", line 54, in wrapper fn(*args, **kwargs) File "C:\Anaconda3\lib\site-packages\django\core\management\commands\runserver.py", line 117, in inner_run self.check(display_num_errors=True) File "C:\Anaconda3\lib\site-packages\django\core\management\base.py", line 390, in check include_deployment_checks=include_deployment_checks, File "C:\Anaconda3\lib\site-packages\django\core\management\base.py", line 377, in _run_check s return checks.run_checks(**kwargs) File "C:\Anaconda3\lib\site-packages\django\core\checks\registry.py", line 72, in run_checks new_errors = check(app_configs=app_configs) File "C:\Anaconda3\lib\site-packages\django\core\checks\urls.py", line 13, in check_url_confi g return check_resolver(resolver) File "C:\Anaconda3\lib\site-packages\django\core\checks\urls.py", line 23, in check_resolver return check_method() File "C:\Anaconda3\lib\site-packages\django\urls\resolvers.py", line 398, in check for pattern in self.url_patterns: File "C:\Anaconda3\lib\site-packages\django\utils\functional.py", line 80, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "C:\Anaconda3\lib\site-packages\django\urls\resolvers.py", line 579, in url_patterns patterns = getattr(self.urlconf_module, "urlpatterns", self.urlconf_module) File "C:\Anaconda3\lib\site-packages\django\utils\functional.py", line 80, in __get__ res = instance.__dict__[self.name] = self.func(instance) File "C:\Anaconda3\lib\site-packages\django\urls\resolvers.py", line 572, in urlconf_module return import_module(self.urlconf_name) File "C:\Anaconda3\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "", line 1006, in _gcd_import File "", line 983, in _find_and_load File "", line 967, in _find_and_load_unlocked File "", line 677, in _load_unlocked File "", line 724, in exec_module File "", line 860, in get_code File "", line 791, in source_to_code File "", line 219, in _call_with_frames_removed File "C:\Users\Emil Lilja\Code\mysite\mysite\urls.py", line 21 path('admin/', admin.site.urls), ^ SyntaxError: invalid syntax Performing system checks...

Two things ...

Look at the error near the bottom of the traceback and notice it says there is a syntax faux pas on line 21 of one of your files. If you find and fix that python will advance to your next error - if any.

And

runserver is asking you to Ctrl-c and do python manage.py migrate --settings=<mysite.settings>

This will ensure your database matches all the models in your project including Django's own models.

1. Yeah i know but I've copied the code straight of the tutorial so getting a SyntaxError seems odd.

2. Don't think it has anything to do with the migration. I just don't see the output of runserver until i terminate it with ctrl-c. Noticed recently that it only does this on Git Bash and not windows Cmd

Well you know what Sherlock Holmes would say. Eliminate the impossible
and what is left must be true.

You can only detect a syntax error by examing your code on line 21. You
need to understand Python in order to make sense of it. Perhaps you
could post that line and the few lines above and below and someone here
might be able to help.

Whether or not doesn't matter when you have a syntax error. Fix that
first and then migrate

 hello...

While using field type null ...

what is difference between "Empty string" and Null=True i.e null ......value for "no data"  in string based field...........?

[Mike Dewhirst]

Empty string is ""
Django likes to convert str=None (ie no value) into an empty string
depending on the RDBMS.

https://docs.djangoproject.com/en/2.1/ref/databases/#null-and-empty-strings
https://docs.djangoproject.com/en/2.1/ref/forms/fields/#django.forms.Field.required

From the latter link ...

"If a |Field| has |required=False| and you pass |clean()| an empty
value, then |clean()| will return a /normalized/ empty value rather than
raising |ValidationError|. For |CharField|, this will be an empty
string. For other |Field| classes, it might be |None|. (This varies from
field to field.)"

It looks like you might have used an existing thread to ask your
question. It is always best to start a new thread when you have a new
question.

Cheers

Mike
