>     f.label :location
>     f.select :location, options_for_select([['Community', 'Community'], ['Learn More', 'Learn More']]), :prompt => "Select

>     f.select :content_type, options_for_select([['Article', 'Article'], ['Gallery', 'Gallery'], ['Video', 'Video']]), :prompt =>
> "Select Type", :id => 'content_type'   end

当表单提交并且出现错误时，表单内容没有值，如果出现错误我想填写表单。

尝试，

   f.input :title, label: 'Title', :input_html =>{ :required => '', :value => f.object.title} 
   do
     f.label :location
     f.select :location, options_for_select([['Community', 'Community'], ['Learn More', 'Learn More']], :selected => f.object.location), :prompt => "Select  Location" ,:collection => displayable_collection   end   li do
     f.label :Type
     f.select :content_type, options_for_select([['Article', 'Article'], ['Gallery', 'Gallery'], ['Video', 'Video']], :selected => f.object.content_type), :prompt =>  "Select Type", :id => 'content_type'
   end

它不是，f对象持有的实例值。这就是我写f.object的原因。您可以直接使用instacen，例如@user.location
