问题描述

current_user 单击图钉时,如何将图像保存到 current_user

When the current_user clicks the pin how can that image be saved to the current_user?

按钮:

  <%= simple_form_for(@inspiration) do |f| %>
    <%= f.hidden_field :image_file_name, value: inspiration.image_file_name %>
    <%= f.hidden_field :image_content_type, value: inspiration.image_content_type %>
    <%= f.hidden_field :image_file_size, value: inspiration.image_file_size %>
    <%= button_tag(type: 'submit', class: "btn btn-primary") do %>
      <span class="glyphicon glyphicon-pushpin"></span>
    <% end %>
  <% end %>

输出

pry(main)> Inspiration.first
 id: 1,
 user_id: 1,
 image_file_name: "choose-optimism.png",
 image_content_type: "image/png",
 image_file_size: 230082,
pry(main)> Inspiration.last
 id: 2, # Creating the issue of the route error & image not rendering
 user_id: 2,
 image_file_name: "choose-optimism.png",
 image_content_type: "image/png",
 image_file_size: 230082,

固定图像的 id 不同,给出错误:没有路线匹配[GET] /system/inspirations/images/000/000/002/medium/choose-optimism.png

The id is different for the pinned image giving the error: No route matches [GET] "/system/inspirations/images/000/000/002/medium/choose-optimism.png"

工作映像具有 001

/ system / inspirations / images / 000/000/001 / medium / choose-optimism.png?1478840469

解决此问题的最佳方法是什么,我可以继续传递不同的ID,但使用同一张图片?

What's the best way to fix this so I can continue to pass different IDs, but use the same image?

控制器

@inspirations = @user.inspirations # Renders Images with Pin Overlayed
@inspiration = current_user.inspirations.build # For the Button

def create
  @inspiration = current_user.inspirations.build(inspiration_params)
  @inspiration.save
  respond_modal_with @inspiration
end


推荐答案

在您的模型中:

has_attached_file :image, url: '/system/inspirations/images/:style/:filename'

但是,执行此操作后,您将必须重新创建首先是灵感,因此它将使用新的URL插值。

However, after you do this, you'll have to recreate your first Inspiration so it will use new URL interpolation.
