what does loginsys do?

Staff conrad | 4232 posts | PythonAnywhere staff | April 23, 2015, 6:04 p.m. | permalink

It is responsible for log in, log out, and register new users. Almost all of the code I got from here

does the exact same code as the github repo run? or does it error as well?

Staff conrad | 4232 posts | PythonAnywhere staff | April 23, 2015, 6:33 p.m. | permalink

app loginsys is exactly the same.. the problem is that on my localhost - evrything is ok, but on your doesn't.

just took a look at your log files and want to clarify how a virtualenv works:

A virtualenv is specific to a webapp on a particular machine and contains the libraries and packages your app depends on. For example, you might create a virtualenv for your webapp on your local machine and install a particular version of flask, django, or requests, etc into it, or you might then create a second virtualenv on your local machine for another project that you are working on, or you might create a third virtualenv on pythonanywhere for your webapp.

The actual source code for your website -- the python and html files you write yourself, that are part of your site -- this is what you would move between machines, but they don't need to and should not be placed in the same folder as your virtualenv.

So if you look at your error log, and go to the very bottom (since it is chronological), you will see that you are having trouble with the file paths. (It can't find settings.py)

I think it's an old log... and he is not to treat the problem

Which database are you using? Could it be that the database is slightly different on your local PC and on PythonAnywhere?

Also, just to double-check -- are you definitely using the same versions of django, etc, locally and on pythonanywhere?

Conrad is right about not mixing virtualenvs and application source code by the way. You should keep your app code at, eg, /home/scorpionby/mysite/, or somewhere like that. You should be able to delete and re-create your virtualenv at any time, totally separately from your code. (that may be worth trying).

The other piece of advice, if you're having database problems, would be to reset your database completely -- delete it, or start again with a new one, and run manage.py migrate...
