Question

我正在使用最好的宝石，我希望用户配置文件中未登录（非当前用户）的字段处于只读模式。 ATM用户可以登录，访问其他用户页面并更改其配置文件选项（它不会保存到数据库中）。它应该设置为如果您不是当前用户，那么所有配置文件信息都将是只读的。

show.html.erb：

<p>Education: <%= best_in_place @user, :education, nil: 'What is your education level?', :type => :select, :collection => [["High school", "High school"], ["Some college", "Some college"], ["Undergraduate", "Undergraduate"], ["Bachelor's", "Bachelor's"], ["Master's", "Master's"], ["PhD", "PhD"], ["Business school", "Business school"], ["Law school", "Law school"], ["Medical school", "Medical school"]] %></p>

用户控制器：

   def update
      @user = if current_user.has_role?(:admin)
            User.find(params[:id])
          else
            current_user
          end
         @user.update_attributes(params[:user])
         respond_with @user
        end

 def edit
      @user = User.find(params[:id])
end

我不确定gem的最佳位置，但对于常规表单，您需要将readonly: true选项添加到视图中的字段中。我假设您的edit视图还为视图提供了@user实例变量。

类似的东西：

<% if current_user.id == @user.id %>
  <p>Education: <%= best_in_place @user, :education, nil: 'What is your education level?', :type => :select, :collection => [["High school", "High school"], ["Some college", "Some college"], ["Undergraduate", "Undergraduate"], ["Bachelor's", "Bachelor's"], ["Master's", "Master's"], ["PhD", "PhD"], ["Business school", "Business school"], ["Law school", "Law school"], ["Medical school", "Medical school"]] %></p>
<% else %>
  <p>Education: <%= best_in_place @user, :education, nil: 'What is your education level?', :type => :select, :collection => [["High school", "High school"], ["Some college", "Some college"], ["Undergraduate", "Undergraduate"], ["Bachelor's", "Bachelor's"], ["Master's", "Master's"], ["PhD", "PhD"], ["Business school", "Business school"], ["Law school", "Law school"], ["Medical school", "Medical school"]], readonly: true %></p>
<% end %>

希望有所帮助。

编辑：

似乎普通的Rails助手选项不可用，因此请尝试直接添加HTML禁用属性，如下所示：

<% if current_user.id == @user.id %>
  <p>Education: <%= best_in_place @user, :education, nil: 'What is your education level?', :type => :select, :collection => [["High school", "High school"], ["Some college", "Some college"], ["Undergraduate", "Undergraduate"], ["Bachelor's", "Bachelor's"], ["Master's", "Master's"], ["PhD", "PhD"], ["Business school", "Business school"], ["Law school", "Law school"], ["Medical school", "Medical school"]] %></p>
<% else %>
  <p>Education: <%= best_in_place @user, :education, nil: 'What is your education level?', :type => :select, :collection => [["High school", "High school"], ["Some college", "Some college"], ["Undergraduate", "Undergraduate"], ["Bachelor's", "Bachelor's"], ["Master's", "Master's"], ["PhD", "PhD"], ["Business school", "Business school"], ["Law school", "Law school"], ["Medical school", "Medical school"]], :html_attrs => {:disabled => true} %></p>
<% end %>

如果不是当前用户，则使字段只读
