[英]Rails Carrierwave upload not uploading
So I'm trying to get a basic carrierwave uploader working for a photography website. 因此,我试图为摄影网站提供一个基本的载波上传器。
I went and generated a scaffold and got the uploader all setup. 我去生成了一个脚手架,并完成了上传程序的所有设置。 the page loads showing the upload box, and it looks like I upload a photo but when I go to the show page it spits out something like
Image: #<ActionDispatch::Http::UploadedFile:0x007fa03f7389a8>
and shows no image. 该页面加载后显示上载框,看起来就像我上载一张照片,但是当我进入显示页面时,它会吐出类似
Image: #<ActionDispatch::Http::UploadedFile:0x007fa03f7389a8>
显示任何图像。
I'm still new to rails so there is probably something really simple that im not seeing here. 我仍然对Rails还是陌生的,所以可能有些非常简单的东西在即时通讯中看不到。
Thanks! 谢谢!
Here is my uploader called image_uploader.rb 这是我的上传器,名为image_uploader.rb
class ImageUploader < CarrierWave::Uploader::Base
include CarrierWave::RMagick
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
here is my show.html.rb 这是我的show.html.rb
<p id="notice"><%= notice %></p>
<p>
<strong>Title:</strong>
<%= @image.title %>
</p>
<p>
<strong>Description:</strong>
<%= @image.description %>
</p>
<p>
<strong>Tag:</strong>
<%= @image.tag %>
</p>
<p>
<strong>Image:</strong>
<%= @image.image %>
</p>
<%= link_to 'Edit', edit_image_path(@image) %> |
<%= link_to 'Back', images_path %>
and this is my images controller 这是我的图像控制器
class ImagesController < ApplicationController
before_action :set_image, only: [:show, :edit, :update, :destroy]
# GET /images
# GET /images.json
def index
@images = Image.all
end
# GET /images/1
# GET /images/1.json
def show
end
# GET /images/new
def new
@image = Image.new
end
# GET /images/1/edit
def edit
end
# POST /images
# POST /images.json
def create
@image = Image.new(image_params)
respond_to do |format|
if @image.save
format.html { redirect_to @image, notice: 'Image was successfully created.' }
format.json { render :show, status: :created, location: @image }
else
format.html { render :new }
format.json { render json: @image.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /images/1
# PATCH/PUT /images/1.json
def update
respond_to do |format|
if @image.update(image_params)
format.html { redirect_to @image, notice: 'Image was successfully updated.' }
format.json { render :show, status: :ok, location: @image }
else
format.html { render :edit }
format.json { render json: @image.errors, status: :unprocessable_entity }
end
end
end
# DELETE /images/1
# DELETE /images/1.json
def destroy
@image.destroy
respond_to do |format|
format.html { redirect_to images_url, notice: 'Image was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_image
@image = Image.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def image_params
params.require(:image).permit(:title, :description, :tag, :image)
end
end
