我想在视图中显示一些“美化”的 json 以用于调试目的。例如,而不是显示:
{"observations"=>{"realtime_start"=>"1776-07-04", "realtime_end"=>"9999-12-31", "observation_start"=>"1776-07-04", "observation_end"=>"9999-12-31", "units"=>"lin", "output_type"=>"1", "file_type"=>"xml", "order_by"=>"observation_date", "sort_order"=>"desc", "count"=>"2541", "offset"=>"0", "limit"=>"10", "observation"=>[{"realtime_start"=>"2013-01-10", "realtime_end"=>"9999-12-31", "date"=>"2012-12-01", "value"=>"1458.750"}, {"realtime_start"=>"2012-12-13", "realtime_end"=>"2012-12-19", "date"=>"2012-11-01", "value"=>"1435.307"}, {"realtime_start"=>"2012-12-20", "realtime_end"=>"2013-01-09", "date"=>"2012-11-01", "value"=>"1435.304"}, {"realtime_start"=>"2013-01-10", "realtime_end"=>"9999-12-31", "date"=>"2012-11-01", "value"=>"1435.303"}, {"realtime_start"=>"2012-11-01", "realtime_end"=>"2012-11-07", "date"=>"2012-10-01", "value"=>"1418.277"}, {"realtime_start"=>"2012-11-08", "realtime_end"=>"2012-11-14", "date"=>"2012-10-01", "value"=>"1418.286"}, {"realtime_start"=>"2012-11-15", "realtime_end"=>"2012-11-22", "date"=>"2012-10-01", "value"=>"1418.285"}, {"realtime_start"=>"2012-11-23", "realtime_end"=>"2012-11-28", "date"=>"2012-10-01", "value"=>"1418.284"}, {"realtime_start"=>"2012-11-29", "realtime_end"=>"9999-12-31", "date"=>"2012-10-01", "value"=>"1418.274"}, {"realtime_start"=>"2012-10-04", "realtime_end"=>"2012-10-10", "date"=>"2012-09-01", "value"=>"1409.636"}]}}
...我想显示:

}]
}
}
当我分配一个变量@beautifiedJson = JSON.pretty_generate(parseHolder) 时,parseHolder 是 json 对象,然后通过以下方式将@beautifiedJson 放在我的视图中:
<%= @beautifiedJson %>
……景色没有美化。当我查看页面源时,json 被格式化(正确的缩进和行),但是,在视图中正确显示的必要 html 格式没有到位。
我的问题是我是正确使用 rails JSON 方法还是需要另一种方法来完成格式化?
