嘿所以我在CarrierWave& amp; MiniMagick今天早上上传的头像图像显示不正确,因为你可以看到在这个截图中突出显示我已经挖了html和控制器,但是找不到有什么问题所以我会在这里发布所有内容,看看是否有第二组眼睛也许能够找到问题。
这是AvatarUploader< CarrierWave ::上传::基地:
所有这些参数都是从我的课程中复制的:
# Process files as they are uploaded:
# process :scale => [200, 300]
process :resize_to_fill => [200, 300]
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
version :tiny do
process resize_to_fill: [20, 20]
end
version :small do
process resize_to_fill: [30, 30]
end
version :profile do
process resize_to_fill: [45, 45]
end
以下是application.html.erb
的摘录注意:我也在使用设计
<% if current_user %>
<%= image_tag(current_user.avatar.tiny.url) if current_user.avatar? %> Hello <%= link_to (current_user.name || current_user.email), edit_user_registration_path %>!
<%= link_to "Sign Out", destroy_user_session_path, method: :delete %>
<% else %>
<%= link_to "Sign In", new_user_session_path %> or <%= link_to "Sign Up", new_user_registration_path %>
<% end %>
最后这是我的用户控制器:
class UsersController < ApplicationController
before_action :authenticate_user!
def update
if current_user.update_attributes(user_params)
flash[:notice] = "User information updated"
redirect_to edit_user_registration_path
else
flash[:error] = "Invalid user information"
redirect_to edit_user_registration_path
end
end
private
def user_params
params.require(:user).permit(:name, :avatar)
end
end
如果您需要查看更多文件,请询问,我会添加它们。
答案 0 :(得分:1)
答案是,你应该使用
image_tag current_user.avatar.url(:tiny)
