Rails 6 我有一个 select_tag 没有下拉列表
Rails 6 I have a select_tag that is not droping down a list
我正在重写一个名为 Emissions Gateway 的应用程序，从 Rails v3.2 到 Rails v6.1.4.1
我有大约 99% 的应用程序被重写并正常工作，但有一部分让我很困惑。
当您删除用户时，它要求您将他们拥有的任何项目移动到不同的用户。这通常会显示一个下拉菜单。模式正在工作，按钮正在工作，但下拉菜单没有显示任何内容，我一直无法弄清楚为什么？
这是具有 select_tag 的特定部分：
= simple_form_for @user, :html => { :method => :delete } do |f|
= select_tag :user_id, options_from_collection_for_select(users_when_being_deleted(@user), "id", "name")
这是名为 users_helper.rb
的文件中名为 users_when_being_deleted 的方法
def users_when_being_deleted(user = nil)
if user
User.where(vendor_id: "current_user.vendor_id").
and(User.where.not(id: @user.id)).order(:name)
else
User.where(vendor_id: "current_user.vendor_id").order(:name)
end
end
下面是单击向下箭头时模态框的外观图片：
这里是users_controller.rb
中的destroy方法
def destroy
# check for vendor manager
@user = User.find(params[:id])
@vendor = @user.vendor
if (@user.id != @vendor.user_manager_id) && params[:user_id].present?
@user.move_data_to_user(params[:user_id])
@user.destroy
flash[:success] = "User removed."
redirect_to users_url
else
redirect_to users_url, notice: "Cannot delete this user."
end
end
这里是模型中的move_data_to_user方法user.rb
def move_data_to_user(new_user_id)
@new_user = User.find_by_id(new_user_id)
self.articles.each { |a| a.user_id = new_user_id ; a.save }
self.audits.update_all(user_id: nil)
self.projects.each do |project|
Audit.create(class_kind: "project", item_id: project.id, action: "unassigned", new_value: self.name, user_id: User.current_user.id, project_id: project.id)
Audit.create(class_kind: "project", item_id: project.id, action: "assigned", new_value: @new_user.name, user_id: User.current_user.id, project_id: project.id) unless @new_user.nil?
end
self.projects.update_all(user_id: new_user_id, vendor_id: self.vendor_id)
self.verified_projects.update_all(user_verified_id: new_user_id)
self.pending_projects.update_all(user_submitted_id: new_user_id)
@new_user.touch
