Rails f.check_box set checked/unchecked values
提问by Jauny
so I got a form helper in rails with a checkbox; I want that checkbox to have values as "thatvalue" or "thisvalue" when checked or unchecked; I haven't found anywhere how to set this up with
所以我在 rails 中得到了一个带有复选框的表单助手；我希望该复选框在选中或未选中时具有“那个值”或“这个值”的值；我还没有找到如何设置它
f.check_box :field
I found something like that
我发现了类似的东西
<%= form.check_box :field, {}, "thisvalue", "thatvalue" %>
but it doesn't work, because I also set :class and :style inside my tag, so having something like
但它不起作用，因为我还在标签中设置了 :class 和 :style，所以有类似的东西
<%= form.check_box :field, {}, "thisvalue", "thatvalue", :class => "checkbox", :style => "display:none;" %>
errors and tells me wrong number of arguments (5 for 4)
错误并告诉我错误的参数数量（5 对 4）
so right now I have to "hack" it in my controller, and set my field depending on if my checkbox is 0 or 1... which is pretty bad.
所以现在我必须在我的控制器中“破解”它，并根据我的复选框是 0 还是 1 来设置我的字段......这很糟糕。
any idea?
任何的想法？

答案很简单
<%= f.check_box :field, {:class => "myclass", :style => "mystyle"}, "checked-value", "unchecked-value" %>
and it works perfectly :)
它完美地工作:)
