Rails Upload YouTube thumbnail from app using YT Gem

Question

I have been having a lot of trouble trying to figure out how to upload thumbnails using the YT Gem. Does anyone know how to help? This is the original tutorial that I was following but it doesn't talk about custom thumbnails. [https://www.sitepoint.com/youtube-api-version-3-rails/][1] I can upload videos just not custom thumbnails.

Thanks very much for any help..

Video Upload Model

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

View

<%= 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 request

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

2. Server renders the videouploads/new.html.erb and the form field @videoupload.upload_thumbnail

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

3. User fills the form and submits

4. You controller with strong params allows those parameters to be read. This are the parameters, you need to focus on "upload_thumbnail". This is where you pass the values for you video thubnail.. It includes different fields like "upload_thumbnail",@original_filename, etc..

   {"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. Create an instance of Video Upload with the params passed from the router in step 4, the params will be those above:

   @video_upload = VideoUpload.new(params)
   

The problem may be that you are not using the whole parameters params[:video_upload], but just

upload_thumbnail: params[:video_upload][:upload_thumbnail]

Which as you can see from above it will equal:

"upload_thumbnail"=>#, 

You still have many other field for the thumbnail, for example

@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"

So maybe would be a good idea to create the object with all the parameters

@video_upload = VideoUpload.new(your_strong_params)

you need to use rails strong params

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

6. Then Save the instance video_upload

   @video_upload.save
   

If this does not solve the problem, you need to stop with the debugger or print to the server with the put ruby syntax the following fields:

puts @video_upload.errors.full_messages

Or check those out with the debug and tell us if you have any error message, as probably you are not saving it.. or maybe
