Ruby on Rails: Büroklammer :: AdapterRegistry :: NoHandlerError in UsersController # update

Question

Was mache ich falsch?

Büroklammer :: AdapterRegistry :: NoHandlerError in Userscontroller # update kein Handler gefunden für "S__28434447.jpg"

@user = User.find(params[:id]) 

    if @user.update(user_params) 
     flash[:notice] = "edit success" 
     redirect_to("https://stackoverflow.com/users/#{@user.id}") 
    end 

users_controller.rb

class UsersController < ApplicationController 
     before_action :authenticate_user 

      def edit 
      @user = User.find_by(id: params[:id]) 
      end 

      def update 
      @user = User.find(params[:id]) 

      if @user.update(user_params) 
       flash[:notice] = "edit success" 
       redirect_to("https://stackoverflow.com/users/#{@user.id}") 
      end 
      end 

     private 

     def user_params 
      params.require(:user).permit(:avatar, :name, :email, :phone_number, :description) 
     end 

end 

Parameter:

{"utf8"=>"✓", 
"authenticity_token"=>"hRL4l1uZtBP8N9uQZeImLSOyn/u10Qc7zXiJBkFvVJvzO7bS6DxGVpIozEu0fjWRAZU1YGsfMgj6bwNT1P1FFg==", 
"user"=>{"name"=>"admin", "avatar"=>"S__28434447.jpg", "email"=>"admin@gmail.com", "phone_number"=>"", "description"=>""}, 
"id"=>"1"} 

edit.html.erb

 <%= form_tag("https://stackoverflow.com/users/#{@user.id}/update", html:{multipart: true}) do %> 
      <div class="form-group"> 
       <p>*ユーザー名</p> 
       <input name="user[name]" value="<%= @user.name %>" class="form-control"> 
      </div> 
      <div class="form-group"> 
       <p>プロフィール画像</p> 
       <input name=user[avatar] type="file" value="<%= @user.avatar %>" class="form-control"> 
      </div> 
      <div class="form-group"> 
       <p>*メールアドレス</p> 
       <input name=user[email] value="<%= @user.email %>" class="form-control"> 
      </div> 
      <div class="form-group"> 
       <p>電話番号</p> 
       <input name=user[phone_number] value="<%= @user.phone_number %>" class="form-control"> 
      </div> 
      <div class="form-group"> 
       <p>自己紹介</p> 
       <input name=user[description] value="<%= @user.description %>" class="form-control"> 
      </div> 

      <div class="actions"> 
       <input type="submit" value="保存" class="btn btn-primary"> 
      </div> 
     <% end %> 

Ich benutze gem Datei gem 'Büroklammer' gem 'aws-sdk', '~> 2.3'

Ich benutze Schienen 5

Ich weiß nicht, wo falsch. Also erzähl mir bitte von den Verbesserungspunkten.

Answer 1

Tun Sie dies

1. diese Zeile entfernen <input name=user[avatar] type="file" value="<%= @user.avatar %>">
2. Und diese Linie <%= file_field_tag :avatar %> anstelle von i.Vj. Code hinzufügen.
