Angular JS: directives executing controller methods

There is a nice and pretty straightforward example:

python - PIP : ImportError: cannot import name IncompleteRead

I got the error:

ImportError: cannot import name IncompleteRead

The solution was reinstalling pip:

sudo easy_install freeze
sudo apt-get remove python-pip
sudo apt-get autoremove
wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py --no-check-certificate
sudo python get-pip.py

Share data among controllers

Use $ rootScope

var app = angular.module('mymodule',[]);
app.controller('Ctrl1', ['$scope','$rootScope',
  function($scope, $rootScope) {
    $rootScope.showBanner = true;
}]);

app.controller('Ctrl2', ['$scope','$rootScope',
  function($scope, $rootScope) {
    $rootScope.showBanner = false;
}]);
