Content_tag escapes the data

Question

span_tag = content_tag(:span, class: "123")

It generates the following html:

<span>{:class=&gt;&quot;123&quot;}</span>

I wonder, what's up with this? Shouldn't it be just <span class="123"></span> which is exactly what I want? Do I necessarily have to use .html_safe?

Answer 1

From doc

content_tag(name, content_or_options_with_block = nil, options = nil, escape = true, &block)

pass empty block:

span_tag = content_tag(:span, class: "123") {}
"<span class=\"123\"></span>"
span_tag = content_tag(:span, class: "123") { 'foo' }
"<span class=\"123\">foo</span>"

Answer 2

Try:

span_tag = content_tag(:span, nil, class: "123")
