Transfer JSON data to Heroku Rails application - ruby-on-rails

Question

I am quite new to Rails and noticed that none of my data from my local environment was being pushed to the Heroku environment using the heroku run rake db:migrate command.In particular I was wondering how to transfer the JSON data to the Heroku environment.

Angular Controller:
myApp.controller("BlogController", function($scope, $http){
$http.get('/assets/blogs.json').success(function(data){
$scope.blogs = data;
String.prototype.trunc = String.prototype.trunc ||
function(n){
// this will return a substring and
// if its larger than 'n' then truncate and append '...' to the string and return it.
// if its less than 'n' then return the 'string'
return this.length>n ? this.substr(0,n-1)+'...' : this;
};
});
});
I am also receiving the following error in my console for the deployed environment: Error: Unknown provider: eProvider <- e

Changing the pattern of the AngularJs controller resolved the issue:
myApp.controller("BlogController", ['$scope', '$http', function($scope, $http){
$http.get('/assets/blogs.json').success(function(data){
$scope.blogs = data;
String.prototype.trunc = String.prototype.trunc ||
function(n){
// this will return a substring and
// if its larger than 'n' then truncate and append '...' to the string and return it.
// if its less than 'n' then return the 'string'
return this.length>n ? this.substr(0,n-1)+'...' : this;
};
});
}]);
