Learned about CORS and browser ajax request crossdomains:

Used a flask plugin (cors) to make this work in debug mode
(boot2docker problem)
First http angular request working on my api :)
Things learned to get my data out of the api json with angular:

ng-repeat is no easy when you don't know how to handle data;
ng-repeat cannot handle duplicates because of its caching algorightm;
you can track the id with $index;
can you track the index with the db key? who knows;
you can play with objects of ng-repeat just like python tuples;
you need to parse json :)
Little code and ideas fixing
