ruby on rails - Why isn't my view variable interpolated inside brackets? -

-

i have code inside rails views/comments/_comments partial:

 <%= render :partial => 'comments/#{@type}' %>

also, passing @type variable through local get: 

missing partial comments/#{@type}

it works if replace following:

<%= render :partial => 'comments/post' %>

so @type not evaluated inside views.

can explain that?

string interpolation in ruby works strings defined double quotation marks ("). should work:

<%= render :partial => "comments/#{@type}" %>

or shorthand applicable if want interpolate value of instance variable:

<%= render :partial => "comments/#@type" %>
