New line after bracket has 8 spaces indentation instead of 4?

After typing the bracket and enter, the next line will has 8 spaces indentation:

            print conn.generate_url(
                    seconds,
                    'GET',

instead of 4:

            print conn.generate_url(
                seconds,
                'GET',

My ~/.vimrc: https://github.com/quantonganh/salt-states/blob/master/vim/vimrc.jinja2

Did I miss something?

@quantonganh ok. I see.

I think we should add this line in your .vimrc

set autoindent

because you already have filetype plugin indent on
