I'm working on a web project using Django framework and python language, actually I'm learning to use it for web programming.
But I have two problems with Django framework:
First: I'v installed PyCharm and Django framework. When I run my project, "ruserver" process proceeds successfully but instantly an error comes out and stops server. This is the exact phrase: "Error: [Errno 10013] An attempt was made to access a socket in a way forbidden by its access permissions". I have unabled my firewall and my antivirus, but no change happened.
I should mention that I'v tested this project in another computer and it absolutely worked well.
Second: I can't access to databases. I primarily know that I should mention type and other stuff about my database in the file "settings.py" but it didn't work. I don't know why. I'v not worked with databases very much before and I'm kinda new. Can anyone help me with details about it, please?
