Railsで画像をバイナリファイルで保存ヘ(^o^)ノ

(￣(ｴ)￣)彡☆

適当にひな形作る

$ rails g scaffold photo image:binary

app/models/photo.rb

class Photo < ActiveRecord::Base
  attr_accessible :image, :picture_file
  
  def picture_file= (file)
    if file
      self.image = file.read
    end
  end
end

app/controllers/photos_controller.rb

#追加
def picture
  @image = Photo.find(params[:id])
  send_data(@image.image)
end

config/routes.rb

#変更
resources :photos do
  member do
    get :picture
  end
end

app/views/photos/_form.html.erb

#変更

<%= f.label :picture_file %>

<%= f.file_field :picture_file %>

app/views/photos/index.html.erb

<% @photos.each do |photo| %>
  <%= image_tag picture_photo_path(photo), :size => '30x30' %> #修正
  <%= link_to 'Show', photo %>
  <%= link_to 'Edit', edit_photo_path(photo) %>
  <%= link_to 'Destroy', photo, method: :delete, data: { confirm: 'Are you sure?' } %>
<% end %>

app/views/photos/show.html.erb

Image:
  <%= image_tag picture_photo_path(@photo), :size => '30x30' %> #修正

これでバイナリーデータで保存して、表示できるヘ(^o^)ノ

でもね… select_dateのおかげでレコード毎にselect文が─=≡Σ((( つ•̀ω•́)つ

うーん、なんか良い方法ないですかね？
