Rails从Helper模块中返回多个content_tags [英] Rails Return multiple content_tags from Helper module
问题描述
我写了以下帮助程序:
def section_to_html(block)
case block [0]。当段落
block.shift
block.each do | value |时,会降低
return content_tag(:p,value)
end
end
end
目前正在分析这些数组。
[段落,这是第一段。 ]
[paragraph,This is the second。,这是一个额外的段落。]
并返回:
< p>这是第一段。< / p>
< p>这是第二个。< / p>
有没有办法累积content_tag?所以它会返回:
< p>这是第一段。< / p>
< p>这是第二个。< / p>
< p>这里有一个额外的段落。< / p>
现在我唯一的解决方案是使用partial。但是,一旦我开始为案例条件添加更多内容,这会变得非常混乱。使用#concat:
$ b
http: //api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-concat
此主题可能有所帮助:
p>I've written the following helper:
def section_to_html (block)
case block[0].downcase
when "paragraph"
block.shift
block.each do |value|
return content_tag(:p, value)
end
end
end
It is currently parsed these arrays.
["paragraph", "This is the first paragraph."]
["paragraph", "This is the second.", "And here's an extra paragraph."]
And it returns:
<p>This is the first paragraph.</p>
<p>This is the second.</p>
Is there a way to accumulate the content_tag? so it returns:
<p>This is the first paragraph.</p>
<p>This is the second.</p>
<p>And here's an extra paragraph.</p>
My only solution right now is to use a partial instead. But that's going to get very messy once I starting adding more to case condition.
Use #concat:
