Rails Hidden field tag - Remove "value" key from parameter

Question

I have this code in my view:

<%= hidden_field_tag :comment_id, '1'%>

It essentially creates this for params

params = {"commit"=>"No Phrase to Add", "comment_id"=>"{:value=>1}"}

I want to extract the comment_id of 1 from the above hash. params[:comment_id][:value] throws an error, because I'm not looking at the key directly but a hash as a string instead.

How can I remove the value key or access the comment_id of 1 above?

goal : "comment_id" => 1

Answer 1

You could use:

eval(params["comment_id"])[:value]
=> 1

The eval would convert the string value of params["comment_id"] into an actual hash, and then you can easily retrieve the value from it.
