Rails使用YT從應用上傳YouTube縮略圖Gem

Question

我一直在嘗試弄清如何使用YT Gem上傳縮略圖時遇到了很多麻煩。有誰知道如何提供幫助？這是我正在關注的原始教程，但它沒有提到自定義縮略圖。 [https://www.sitepoint.com/youtube-api-version-3-rails/][1] 我可以上傳視頻而不是自定義縮略圖。

非常感謝您的幫助..

視頻上傳模式

class VideoUpload < ActiveType::Object 
    attribute :file, :varchar 
    attribute :title, :varchar 
    attribute :description, :text 
    attribute :upload_thumbnail, :varchar 

    validates :file, presence: true 
    validates :title, presence: true 
    validates :upload_thumbnail, presence: true 

    def upload!(user) 
    account = Yt::Account.new access_token: user.token 
    account.upload_video self.file, title: self.title, description: self.description, upload_thumbnail: self.upload_thumbnail 
    end 
end 

VideoUploadController

def create 
    @video_upload = VideoUpload.new(
    title: params[:video_upload][:title], 
    description: params[:video_upload][:description], 
    upload_thumbnail: params[:video_upload][:upload_thumbnail], 
    file: params[:video_upload][:file].try(:tempfile).try(:to_path) 
) 

    if @video_upload.save 
    uploaded_video = @video_upload.upload!(current_user) 

    if uploaded_video.failed? 
     flash[:error] = 'There was an error while uploading your video...' 
    else 
     Video.create({ 
     link: "https://www.youtube.com/watch?v=#{uploaded_video.id}", 
     uid: uploaded_video.id, 
     title: uploaded_video.title, 
     description: uploaded_video.description 
     }) 

     flash[:success] = 'Your video has been uploaded!' 
    end 

    redirect_to root_url 
    else 
    render :new 
    end 
end 

查看

<%= form_for @video_upload do |f| %> 
    <%= render 'shared/errors', object: @video_upload %> 

    <div class="form-group"> 
    <%= f.label :file %> 
    <%= f.file_field :file, class: 'form-control', required: true %> 
    </div> 

    <div class="form-group"> 
    <%= f.label :upload_thumbnail %> 
    <%= f.file_field :upload_thumbnail, class: 'form-control', required: true %> 
    </div> 

    <div class="form-group"> 
    <%= f.label :title %> 
    <%= f.text_field :title, class: 'form-control', required: true %> 
    </div> 

    <div class="form-group"> 
    <%= f.label :description %> 
    <%= f.text_area :description, class: 'form-control', cols: 3 %> 
    </div> 

    <%= f.submit 'Upload', class: 'btn btn-primary' %> 
<% end %>

Answer 1

1. GET請求

   GET "videouploads/new", "videouploads#new" 
   

2. 服務器呈現videouploads/new.html.erb和表單字段@videoupload.upload_thumbnail

   <div class="form-group"> 
       <%= f.label :upload_thumbnail %> 
       <%= f.file_field :upload_thumbnail, class: 'form-control', required: true %> 
   </div> 
   

3. 用戶填寫表單並提交

4. 您控制器具有較強的PARAMS允許讀取這些參數。這是參數，您需要關注"upload_thumbnail"。 這是你值傳遞給你的視頻thubnail。它包括像"upload_thumbnail"，@original_filename等不同領域..

   {"utf8"=>"✓", 
   "authenticity_token"=>"somecode", 
   "video_upload"=>{ 
        ..a sequence of fields then.., 
        "upload_thumbnail"=>#, 
        @original_filename="protest_3.png", 
        @content_type="image/png", 
        @headers="Content-Disposition: form-data; 
        name=\"video_upload[upload_thumbnail]\"; 
        filename=\"protest_3.png\"\r\nContent-Type: image/png\r\n">, 
        "title"=>"o iuiou goiug oiug piu gpiugpiu ", 
        "description"=>"yg ouyg ouyg piu gpugpiu piuhpiuhpiuh [ io hio h; ['o ih[oi [oih [' oih "}, 
        "commit"=>"Upload" 
        } 
   

5. 與路由器在步驟4中通過PARAMS創建視頻上傳實例，該params將是那些上面：

   @video_upload = VideoUpload.new(params) 
   

的問題可能是你沒有使用全參數 params[:video_upload]，只是

upload_thumbnail: params[:video_upload][:upload_thumbnail] 

正如你可以看到從上面這將等於：

"upload_thumbnail"=>#, 

你還有很多其他領域的縮略圖，例如

@original_filename="protest_3.png", 
@content_type="image/png", 
@headers="Content-Disposition: form-data; 
name=\"video_upload[upload_thumbnail]\"; 
filename=\"protest_3.png\"\r\nContent-Type: image/png\r\n">, 
"title"=>"o iuiou goiug oiug piu gpiugpiu ", 
"description"=>"yg ouyg ouyg piu gpugpiu piuhpiuhpiuh [ io hio h; ['o ih[oi [oih [' oih "}, 
"commit"=>"Upload" 

所以也許會是一個好主意，創建對象的所有參數

@video_upload = VideoUpload.new(your_strong_params) 

你需要使用軌強PARAMS

http://weblog.rubyonrails.org/2012/3/21/strong-parameters/

然後保存實例video_upload

@video_upload.save 

如果這不解決問題，您需要停止使用調試器或使用打印到服務器的Ruby語法以下字段：

puts @video_upload.errors.full_messages 

或檢查出那些與調試，並告訴我們，如果您有任何錯誤消息，因爲很可能你不保存它..或者可能
