When I do this: <%= f.association :user, :collection => User.where(:country_id => 1) %>
当我这样做时：<％= f.association：user，：collection => User.where（：country_id => 1）％>
My dropdown is populated with lines like this: #<User:0x0000010b98d170>
我的下拉列表中填充了这样的行：＃
Instead, I would like to display an email, that is tied to the id of the users.
相反，我想显示一封与用户ID相关联的电子邮件。
I have yet to find how to override the value / content defaults of simple_form when using associations.
我还没有找到在使用关联时如何覆盖simple_form的值/内容默认值。
Can anyone help?
有人可以帮忙吗？

Although the page on github (https://github.com/plataformatec/simple_form) didn't say, but I guess it's the same as the example f.input :age, :collection => 18..60
虽然github上的页面（https://github.com/plataformatec/simple_form）没有说，但我猜它与示例f.input相同：age，：collection => 18..60
You could use :label_method and :value_method:
您可以使用：label_method和：value_method：
f.association :user, :collection => User.where(:country_id => 1), :label_method => :name, :value_method => :id
I did not use it before. Please tell me if it does not work.
我之前没用过它。请告诉我它是否不起作用。
