我有一个用户模型的嵌套资源图片。如果我尝试使用“remote_file_url”上传图片,它会将图片上传到carrierwave tmp 目录,但不会将它们移动到实际目录。那“应该”是一个验证问题。但事实并非如此。它在控制台中工作得很好:
p = Picture.find(360)
p.remote_file_url = "http://example.com/somepic.jpg"
p.save!
我用图片更新用户的请求的参数:
"user"=>{"pictures_attributes"=>{"0"=>{"remote_file_url"=>"http://example.com/somepic.jpg", "id"=>"359"}
如果我在没有 remote_file_url 的情况下上传(只是输入文件字段),它可以工作:
"user"=>{"pictures_attributes"=>{"0"=> { "file"=>#<ActionDispatch::Http>, "remote_file_url"=>"", "id"=>"359"}
当我使用“remove_file”功能时也会出现同样的问题。在控制台中工作得很好,但不适用于视图/控制器更新。
====================
更新
控制器:
def update
@user = current_user
if @user.update_attributes!(params[:user])
respond_to do |format|
format.js { render :json => @user.to_json(:methods => [:pictures]) }
format.html {redirect_to :back, :notice => "Successfully updated user."}
end
else
render :action => 'edit'
end
end
图片型号:
class Picture < ActiveRecord::Base
attr_accessible :file, :file_cache, :remove_file, :position, :remote_file_url
mount_uploader :file, PictureUploader
belongs_to :user
end
用户模型
# encoding: UTF-8
class User < ActiveRecord::Base
attr_accessible :remote_file_url, :beta_token, :wants_gender, :gender, :radius, :email, :password, :password_confirmation, :remember_me, :region, :latitude, :longitude, :gmaps, :pictures_attributes
has_many :pictures, :dependent => :destroy
accepts_nested_attributes_for :pictures, :allow_destroy => true
end
非常基本的东西......我删除了用户模型的设计定义......
= simple_form_for @user, :url => profile_path(@user) do |f|
%ul.profiles.users
- @user.pictures.each_with_index do |picture, i|
%li.user
.fields
= f.simple_fields_for :pictures, picture do |picture_from|
- if picture.file.present?
= picture_from.input :_destroy, :as => :boolean
= picture_from.input :position
= picture_from.input :file
= picture_from.input :remote_file_url, :as => :hidden
= picture_from.input :file_cache
