Opening link in new tab, leads to white screen

[itaditya]

Whenever a user clicks on link, content fades, white screen appears and then new content is displayed - Good

If a user clicks on a link while holding Ctrl key then white screen appears, relevant link opens in separate tab (inactive) but this tab (active one, from which we clicked the link) still has the white screen. - Bad

To fix this we have to avoid the fading animation when user opens a link while holding Ctrl key

I get this error while running python manage.py syncdb and other python manage.py statements.

Hey @ubarsaiyan, please use HOST as localhost and port as 3306. Let me know if you still have problems in setting up. :-)

[ubarsaiyan]

@RishabhJain2018 I just ran the command python manage.py syncdb as mentioned in the docs and it threw the above error. Where should I use HOST as localhost and port as 3306.

[RishabhJain2018]

The error message shows that on line 123 in settings.py you have to add these details.

[ubarsaiyan]

I'm sorry but I can't set this up. After plugging in the HOST and port in settings.py, it threw error related to EMAIL_HOST and other variables from line 272 onwards in settings.py. After I plug some constant values to them it shows another long error where the last few lines are

[RishabhJain2018]

@ubarsaiyan The error says that you are missing some libraries. Please refer https://stackoverflow.com/a/25906181/6099150 in order to install them and then try to run it again.

@RishabhJain2018 After resolving this and many other errors it finally gives the error that there is no database called "connect"

python manage.py syncdb
