运行下面的代码时出现以下异常:

uninitialized constant ActionView::CompiledTemplates::Current

Controller :

class UserStepsController < ApplicationController
include Wicked::Wizard
  steps :finishing_step

  def show
    @user = Current.user
    render_wizard
  end

  def update
    render_wizard
  end
private
    def finish_wizard_path
      current_user.update_attributes(complete: true)
      redirect_to root_path

end

表格:

<%= form_for Current.user, url: wizard_path do |f| %>
<div><%= f.label :first_name, "First Name" %><br />
    <%= f.text_field :first_name %></div>

    <%= f.date_select :date_of_birth, start_year: 1900 %></div>
  <div><%= f.label :address_first_line, "Address (first line)" %><br />
    <%= f.text_field :address_first_line %></div>
  <div><%= f.label :address_second_line, "Address (second line)" %><br />
    <%= f.text_field :address_second_line %></div>
  <div><%= f.label :city, "City" %><br />
    <%= f.text_field :city %></div>
  <div><%= f.label :nationality, "Nationality" %><br />
    <%= country_select(:user, :nationality, {selected: "UG"}) %></div>
    <div>
    <%= f.label :avatar %>
    <%= f.file_field :avatar %>
  </div>
  <div>
    <%= f.label :terms_of_service, "Agree to Terms of Service" %> <br>
    <%= f.check_box :terms_of_service %>
  </div>
  <div><%= f.submit "Register" %></div>
  <% end %>
<%= render "devise/shared/links" %>

问题是 Rails 无法找到您在 form_for 中使用的类 Current。它正在查看 View 的 namespace ，这就是为什么您会收到稍微神秘的错误消息。如果确实存在一个类 Current 那么您将能够使用 ::Current.user 访问它，但我怀疑它不存在。

通常，当前用户是通过使用 devise 的方法 current_user 来访问的。值得仔细检查您应该如何访问当前用户。
