问题描述
我正在处理一个需要 ActiveStorage has_many_attached :photos 情况在 Location 模型上的项目.
I'm working on a project that requires an ActiveStorage has_many_attached :photos situation on a Location model.
我在下面设置了代码，但是在尝试上传表单时，我收到以下错误:
I have the code set up below, but when attempting to upload a form, I receive the following error:
ActiveSupport::MessageVerifier::InvalidSignature in
LocationsController#attach_photo
这是将文件添加"到特定父记录(即:Location 记录)的附件集中的方式吗?
Is this the way to "add" a file to the set of attachments for a particular parent record (i.e: a Location record)?
class Location < ApplicationRecord
...
has_many_attached :photos
...
end
位置控制器
class LocationsController < ApplicationController
...
def attach_photo
@location = Location.find(params[:id])
@location.photos.attach(params[:photo])
redirect_to location_path(@location)
end
...
end
查看
<%= form_tag attach_photo_location_path(@location) do %>
<%= label_tag :photo %>
<%= file_field_tag :photo %>
<%= submit_tag "Upload" %>
<% end %>
查看
resources :locations do
member do
post :attach_photo
end
end
推荐答案
确保在 form_tag 中添加 multipart: true.它生成 enctype="multipart/form-data".
Make sure to add multipart: true in form_tag. It generates enctype="multipart/form-data".
form_tag 默认不负责，必须有(如果附加文件).
form_tag by default not responsible for it, must have it (if attaching a file).
multipart/form-data 没有编码字符.此值是必需的当您使用具有文件上传控件的表单时
表格:
<%= form_tag attach_photo_location_path(@location), method: :put, multipart: true do %>
<%= label_tag :photo %>
<%= file_field_tag :photo %>
<%= submit_tag "Upload" %>
<% end %>
还有:
将 post 更改为 put 方法，我们正在更新而不是创建 幂等性
Change post to put method, We are updating not creating Idempotency
resources :locations do
member do
put :attach_photo
end
end
