Mojo Template, passing dynamic index to array.

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi Monks!!

I am trying to pass a dynamic value to print a value out of an array using Mojo::Template, getting syntax errors, is there a way to do that?

The code works if its like this:

<% $local->{ place }[ 0 ]{ street } %>
I'd like to pass the index number dynamic using the example below:

Code snipped from the .ep template file:

<p> Location: <br/> <% $local->{ place }[ %> <%= $number %> <% ]{ street } %> </p>
<%= $number %>, can be 0,1,2,3...

    Did you try this? It's just one chunk of perl.

    <% $local->{ place }[ $number ]{ street } %>

    According to Mojo::Template please try
    <p> Location: <br/> <%= $local->{place}[ $number ]{street} %> </p>

    > The code works if its like this: <% $local->{ place }[ 0 ]{ street } %>

    Unlikely, the = is missing in <%= to insert the value

    Why not keep it simple and pass $street?

      Not sure why this got downvoted, passing a few variables with the values for the 'row' in question in most cases makes more sense than passing an entire data structure then displaying one 'row' from a result set.

        I understood $number as loop var, loading it into a temporary $street var would lead to more code.

        YMMV...

        Maybe because AnonyMonk in this case was inferring an XY problem when there really isn't one. The OP actually needs to know how to do what he was trying to do; offering him a kludgy workaround isn't doing him any favors.
