回形針節能問題

這是我的模型回形針節能問題

class User < ActiveRecord::Base 
    has_attached_file :profpic, 
        :styles => { :medium => "300x300>", :thumb => "100x100>" }, 
        :default_url => "/assets/blonde_user.png" 
    validates_attachment_content_type :profpic, :content_type => /\Aimage\/.*\Z/

這是我的控制器方法

def uploadpic 
    p "=========================+++++++++++++++" 
    p params["user"]["profpic"] 
    # current_user.profpic = params["user"]["profpic"] 
    # current_user.profpic_file_name = params["user"]["profpic"] 
    p "=================================" 
    p params 
    p params[:user] 
    current_user.profpic = params["user"]["profpic"] 
    current_user.save 
    p "==================================" 
    redirect_to "/profile" 

    end

，我的看法是一樣

<div class="picture"> 
        <%= form_for current_user, :url => '/uploadpic', :html => { :multipart => true } do |form| %> 
        <%= form.file_field :profpic %> 
         <%= image_tag current_user.profpic.url %> 
        <% end %> 
       </div>

在這個表單提交即時得到這樣的錯誤

Paperclip::AdapterRegistry::NoHandlerError in ProfilesController#uploadpic

，並在我的終端，我得到的輸出所有打印之類的語句

Parameters: {"utf8"=>"✓", "authenticity_token"=>"9J2MdO7Ok1sfP13n6R97so1W/HRI0RiDsHJYiOy6B4Q=", "user"=>{"profpic"=>"n.jpg"}} 
    User Load (0.2ms) SELECT `users`.* FROM `users` WHERE `users`.`id` = 1 ORDER BY `users`.`id` ASC LIMIT 1 
"=========================+++++++++++++++" 
"n.jpg" 
"=================================" 
{"utf8"=>"✓", "_method"=>"patch", "authenticity_token"=>"9J2MdO7Ok1sfP13n6R97so1W/HRI0RiDsHJYiOy6B4Q=", "user"=>{"profpic"=>"n.jpg"}, "controller"=>"profiles", "action"=>"uploadpic"} 
{"profpic"=>"n.jpg"} 
Completed 500 Internal Server Error in 4ms

幫助。

你的'profpic'參數似乎是一個字符串不是一個正確的類。確保你在表單標記中有'multipart'屬性。 – Eru

這是你的整體觀點還是局部？如果它是局部的，那麼確保任何包裝表單元素具有'multipart：true'作爲html選項。 –

您應該將GET更改爲POST。 GET通常在form_for標籤中。當它更改爲POST時，它將工作。

<%= form_for current_user, :url => '/uploadpic', :html => { :multipart => true, :method => 'POST' } do |form| %>
