将JSON数据传输到Heroku Rails应用程序

Question

我对Rails颇为陌生，并且注意到我的本地环境中的任何数据都没有被使用heroku run rake db:migrate命令推送到Heroku环境。

特别是我想知道如何将JSON数据传输到Heroku环境。

宝石文件：

source 'https://rubygems.org' 

gem 'figaro' 
gem 'angular-rails' 
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails' 
gem 'rails', '4.2.1' 
# Use postgresql as the database for Active Record 
gem 'pg' 
# Use SCSS for stylesheets 
gem 'sass-rails', '~> 5.0' 
# Use Uglifier as compressor for JavaScript assets 
gem 'uglifier', '>= 1.3.0' 
# Use CoffeeScript for .coffee assets and views 
gem 'coffee-script', '~> 2.2.0' 
# See https://github.com/rails/execjs#readme for more supported runtimes 
# gem 'therubyracer', platforms: :ruby 

# Use jquery as the JavaScript library 
gem 'jquery-rails' 
# Turbolinks makes following links in your web application faster. Read more: https://github.com/rails/turbolinks 
# gem 'turbolinks' 
# Build JSON APIs with ease. Read more: https://github.com/rails/jbuilder 
gem 'jbuilder', '~> 2.0' 
# bundle exec rake doc:rails generates the API under doc/api. 
gem 'sdoc', '~> 0.4.0', group: :doc 

# Use ActiveModel has_secure_password 
gem 'bcrypt', '~> 3.1.7' 

# Use Unicorn as the app server 
# gem 'unicorn' 

# Use Capistrano for deployment 
# gem 'capistrano-rails', group: :development 

group :development, :test do 
    # Call 'byebug' anywhere in the code to stop execution and get a debugger console 
    gem 'byebug' 

    # Access an IRB console on exception pages or by using <%= console %> in views 
    gem 'web-console', '~> 2.0' 

    # Spring speeds up development by keeping your application running in the background. Read more: https://github.com/rails/spring 
    gem 'spring' 
gem 'rails_12factor', group: :production 

end 

/config/environments/production.rb：

Rails.application.configure do 

    config.cache_classes = true 


    config.eager_load = true 

    config.consider_all_requests_local  = false 
    config.action_controller.perform_caching = true 


    config.serve_static_files = ENV['RAILS_SERVE_STATIC_FILES'].present? 

    config.assets.js_compressor = :uglifier 

    config.assets.compile = true 


    config.assets.digest = true 


    config.log_level = :debug 


    config.i18n.fallbacks = true 

    config.active_support.deprecation = :notify 

    config.log_formatter = ::Logger::Formatter.new 

    config.active_record.dump_schema_after_migration = false 

    config.action_mailer.delivery_method = :smtp 
end 

角控制器：

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; 
    }; 

    }); 
}); 

我还收到以下错误在我的控制台部署环境：Error: Unknown provider: eProvider <- e

改变AngularJs控制器的模式解决了这个问题：

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; 
    }; 

    }); 
}]);
