Einzelne Datei entfernen, wenn mehrere Datei-Uploads Carrierwave

Question

Ich habe in Teil this Tutorial zum Entfernen einer einzigen Datei bei der Verwendung mehrerer Datei-Uploads mit Carrierwave gefolgt. Das Entfernen eines einzelnen Bildes funktioniert zwar korrekt, aber ich erhalte Fehler in meiner Browser-Konsole und in der Rails-Server-Ausgabe. Mein Code:

Controller:

def destroy 
    if params[:index] 
    remove_image_at_index(params[:index].to_i) 
    redirect_to :back 
    else 
    authorize @job 
    @job.destroy 
    respond_to do |format| 
     format.html { redirect_to real_property_sales_url } 
    end 
    end 
end 

def remove_image_at_index(index) 
    remain_images = @job.photos 
    deleted_image = remain_images.delete_at(index) 
    deleted_image.try(:remove!) 
    @job.photos = remain_images 
end 

Route:

resources :real_property_sales 

link_to:

<%= link_to real_property_sale_path(@job, index: index), method: :delete, data: { confirm: 'Are you sure?' }, :remote => true do %> 
    <span class="fa-stack fa-lg"> 
    <i class="fa fa-circle-o fa-stack-2x"></i> 
    <i class="fa fa-times fa-stack-1x"></i> 
    </span> 
<% end %> 

Server Ausgabe:

Answer 1

Ich löste dies durch head :no_content mit:

def destroy 
    if params[:index] 
    remove_image_at_index(params[:index].to_i) 
    head :no_content 
    else 
    authorize @job 
    @job.destroy 
    respond_to do |format| 
     format.html { redirect_to real_property_sales_url } 
    end 
    end 
end
