到目前为止,我已设法上传文件：
# In new.html.erb <%= file_field_tag 'upload[file]' %>
并访问控制器中的文件
# In controller#create @text = params[:upload][:file]
解决方法
完整的例子
例如,上传包含联系人的导入文件.您不需要存储此导入文件,只需处理它并将其丢弃即可.
路线
的routes.rb
resources :contacts do
collection do
get 'import/new',to: :new_import # import_new_contacts_path
post :import # import_contacts_path
end
end
形成
意见/联系人/ new_import.html.erb
<%= form_for @contacts,url: import_contacts_path,html: { multipart: true } do |f| %>
<%= f.file_field :import_file %>
<% end %>
调节器
控制器/ contacts_controller.rb
def new_import
end
def import
begin
Contact.import( params[:contacts][:import_file] )
flash[:success] = "<strong>Contacts Imported!</strong>"
redirect_to contacts_path
rescue => exception
flash[:error] = "There was a problem importing that contacts file.<br>
<strong>#{exception.message}</strong><br>"
redirect_to import_new_contacts_path
end
end
联系型号
车型/ contact.rb
def import import_file
File.foreach( import_file.path ).with_index do |line,index|
# Process each line.
# For any errors just raise an error with a message like this:
# raise "There is a duplicate in row #{index + 1}."
# And your controller will redirect the user and show a flash message.
end
end
希望有所帮助！
