在我看来,我有几箱检查箱,以防:
<%= check_box "product[pr_attributes]", "ag_type", {:checked => @product.issenior?, :multiple => true, :checked => true}, checked_value = "ag:senior", unchecked_value = nil %>Senior(65-100)
问题在于,当我揭开一个缺省并挽救这些变化时,它就退到被检查的国家。 我如何解决这一问题?
您是否打算为<代码>提供两种选择钥匙:checked?
如同第二个“<代码>:checked =>”;真实的正在引起你的问题。
i think the best way to do this in your case is use check_box_tag since your doing multiple answers for one attribute
syntax
检查箱:标签“id”、“价值”、“boolean_if_checked”
阁下:
“产品[pr_attributes][]”,“ag_type”,@product.issenior?,{} %>
然后,在“产品”之后,仅添加“灰色”的其他特性。 是谁?
这样,你就可以为从业者创建多种检查箱,然后当你提交表格时,从业者将成为你们的选择。
