除了content_tag:i
之外,为什么显示所有content_tags def sign_full_tag(group, obj, name, input_type="text", size="12", popover=true)
content_tag :div, class: "row" do
content_tag :div, class: "col-md-" + size do
content_tag :div, class: "form-group left-inner-addon" + class_for_invalid_input(obj, name) do
content_tag(:i, "", class: "fa fa-user fa-fw text-muted") # NOT DISPLAY!!!
group.text_field( name,
class: "form-control" + (popover ? " popover-add" : ""),
id: name.to_s.gsub("_", "-"),
type: input_type,
placeholder: "#{t('sign_up.placeholder.' + name.to_s)}",
data: { container: "body",
toggle: "popover",
placement: "bottom",
content: (popover ? "#{t('sign_up.popover.' + name.to_s)}" : nil) })
end
end
end
end
当我渲染这个帮手时,我不会看到标签"我"在我的浏览器中。 这应该怎么做?
答案 0 :(得分:2)
这是因为只返回块中的最后一个语句。你必须连接这两个语句,以便它作为一个字符串返回:
content_tag(:div, etc etc) do
content_tag(:i, "") + group.text_field(name, etc etc)
end
