Swiftで空のimageViewをadd

Swift 
        //空のImageViewを貼る
        var frame = CGRectMake(0,0,1000,1000)
        UIGraphicsBeginImageContext(frame.size)
        var context = UIGraphicsGetCurrentContext();
        CGContextSetFillColorWithColor(context,UIColor.whiteColor().CGColor);
        let uiImage:UIImage = UIGraphicsGetImageFromCurrentImageContext()
        UIGraphicsEndImageContext()
        self.imageView = UIImageView(image:uiImage)
        self.baseUiView.addSubview(self.imageView)

SwiftでViewをaddとremove

Swift 
                    //remove
                    self.readCanvas?.removeFromSuperview()
                    self.drawCanvas?.removeFromSuperview()
                                        
                    //ReadCanvas
                    self.readCanvas = UIView(frame:self.canvasFrame);
                    self.readCanvas.backgroundColor = UIColor.clearColor()
                    self.baseUiView.addSubview(self.readCanvas);
                    
                    //DrawCanvas
                    self.drawCanvas = UIView(frame:self.canvasFrame);
                    self.drawCanvas.backgroundColor = UIColor.clearColor()
                    self.baseUiView.addSubview(self.drawCanvas);

Rails+Grape

ruby rails

Grapeのインストール

$ vim Gemfile
gem 'grape'
gem 'grape-jbuilder'

$ bundle install

APIディレクトリの作成

$ cd app/
$ mkdir api
$ vim api/api.rb
class API < Grape::API
  prefix "api"
  version 'v1', :using => :path
  format :json
  mount Users_API
end

$ vim /api/users_api.rb
class Users_API < Grape::API
  resource "users" do

    desc "returns all users"
    get do
      Books.all
    end
    
    desc "return a users"
    params do
      requires :id, type: Integer
    end
    get ':id' do
      Users.find(params[:id])
    end

  end
end

パスの設定

$ vim config/application.rb
module Fiddlercrab
  class Application < Rails::Application
    ・・・・
    config.autoload_paths += %W(#{config.root}/api)
  end
end

ルーティングをチェック

$ rake routes

テーブルの作成例

rails g model users name:text comment:text icon_url:text
rails g model feeds user_id:integer user_name:text icon_url:text comment:text 
rails g model feed_comments feed_id:integer user_id:integer user_name:text icon_url:text comment:text 
rake db:create
rake db:migrate
rake db:migrate:reset

Railsアプリ作成memo

新規アプリを作る

$ rails new sample -d mysql
$ cd sample
(bundleをスキップする場合)
$ rails new sample -d mysql --skip-bundle

コントローラーを作る

cd /root/sample/app/controllers
rails generate controller test

コントローラーtest

class TestController < ApplicationController

def hello
  render:text=>'hello'
end

def bye
  render:text=>'bye'
end

end

MySQL接続

//config/database.ymlの内容でデータベースを作る
$ rake db:create

ルーティングを作成

$ vim config/routes.rb
-------------
Rails.application.routes.draw do
  match ':controller(/:action(/:id))', via: [ :get, :post, :patch ]
end
-------------

ルーティングをcheck

$ rake routes

サーバー起動

$ rails s --port=80
