[英]Ruby on Rails image_tag not displaying the image
在gemfile中,我安裝了carrierwave,以允許用戶上傳個人資料圖像。 我按照此railscast中的說明進行了一些操作-http : //railscasts.com/episodes/253-carrierwave-file-uploads
gem 'carrierwave'
但是,圖像未與image_tag一起顯示。 我可以通過在沒有image_tag的情況下對其進行測試來查看圖像目錄。 我還瀏覽了圖像目錄以確保存儲了圖像。 我可以在導演“ / uploads / user / image / 110 /”中看到它
在視圖中,它顯示圖像網址“ /uploads/user/image/110/thumb_IMG_0017.JPG”
<%= @user.image_url(:thumb).to_s %>
添加圖片標簽不會顯示任何內容
<%= image_tag @user.image_url(:thumb).to_s %>
圖像上傳器
class ImageUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
#include CarrierWave::RMagick
include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
storage :file
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
version :thumb do
process :resize_to_limit => [200, 200]
end
end
控制者
def show
@user = User.find(params[:id])
...
end
private
def user_params
params.require(:user).permit(:name, :email, :password, :password_confirmation, :image)
end
模型
class User < ActiveRecord::Base
...
mount_uploader :image, ImageUploader
...
end
例如,直接查詢用戶110的數據庫將顯示以下內容
User.find(110).image_url(:thumb)
User Load (2.1ms) SELECT "users".* FROM "users" WHERE "users"."id" = ? LIMIT 1 [["id", 110]]
=> "/uploads/user/image/110/thumb_IMG_0017.JPG"
設置載波后,需要重新啟動服務器。 這將解決所有問題。
好的,我檢查了服務器日志
Checked the server log looks like a routing issue - Started GET "/uploads/user/image/111/thumb_IMG_1355.JPG" for 127.0.0.1 at 2014-07-12 11:00:29 +0100
ActionController::RoutingError (No route matches [GET] "/uploads/user/image/111/thumb_IMG_1355.JPG"):
通過進入config / environments / production.rb和development.rb並將以下內容設置為true,似乎可以解決該問題!
config.serve_static_assets = true
