如何在轨道中使用本地图像作为单选按钮?
我猜可以使用collection_radio_buttons帮助器,但是如何集成本地图像呢?
此代码段显示了带有以下文字的单选按钮:
cfg.CreateMap<Dto.Member, Member>()
.ConstructUsing((memberDto, context) => {
switch (memberDto.MemberType)
{
case "PersonMember":
return context.Mapper.Map<PersonMember>(memberDto);
case "CompanyMember":
return context.Mapper.Map<CompanyMember>(memberDto);
default:
throw new ArgumentOutOfRangeException($"Unknown MemberType {memberDto.MemberType}");
}
});
cfg.CreateMap<Dto.Member, PersonMember>()
.ForMember(dest => PersonMember.PersonMemberId,
opt => opt.MapFrom(src => src.MemberId));
cfg.CreateMap<Dto.Member, CompanyMember>()
.ForMember(dest => CompanyMember.CompanyMemberId,
opt => opt.MapFrom(src => src.MemberId));
我是否必须将 b.radio_button 替换为 image_tag ?
答案 0 :(得分:1)
是,而不是b.text,您可以使用image_tag显示图片而不是文字
#I have image in app/assets/images as One.png,Two.png and so on.
<%= f.collection_radio_buttons(:paket, [[1, 'One'] ,[2, 'Two'], [3, 'Three']], :first, :last) do |b| %>
<%= b.label { b.radio_button + image_tag('/'+b.text+'.png') } %>
<% end %>
