How can I see my uploaded images?

Question

Ruby version 2.2.4 Rails version 5.0.0.1 Carrierwave

Hello people

I am a totally beginner in RoR and after long hours I finally uploaded an picture from my android app to ruby on rails. I have the code from a tutorial which provides the upload function. However the function how you can see the picture is missed. How can I implement this in ruby on rails? I want to see the pictures in a table

Here is what I have so far

And here is the code: views/items/inde.html.erb

h1>Rails-API-Fileupload-tutorial-Cariierwave-Single</h1>
<h2>Listing documents</h2>

<table>
  <thead>
    <tr>
      <th>Filename</th>
      <th></th>
      <th></th>
    </tr>
  </thead>

  <tbody>
    <% @items.each do |item| %>
      <tr>
        <td><%= item.id %></td>
        <td><%= item%></td>
      </tr>
    <% end %>
  </tbody>
</table>

<br>

routes.rb

Rails.application.routes.draw do
  resources :items, :pictues

  root to: redirect('/items')

  post  to: 'items'
end

UPDATE: Hello People, thanks for your fast help. When I use <%= image_tag item.picture %> I get this

Are there some other ideas?

UPDATE: I think I cannot see the pictures because I have a routing problem. When I right click on a picture and want to open in new browser I get

ActionController::RoutingError: No route matches [GET] 

What can I do to fix this?

UPDATE: My Uploadfolder is outside of Ruby and Rails folder. Should it be in the public ordner instead?

Answer 1

<td><%= item%></td>

should be something like :

edit sorry I forgot the image tag...

<td><%= image_tag item.picture %></td>

Answer 2

要显示图像，请使用image_tag 。

<%= image_tag item.picture_url %>
