Re^3: How do I cope with nested TMPL_VAR in HTML::Template::Pro?

If you template snippet would work, the data input for it would look like

$tmpl->param(loopname => [
    {
        anothervariable => 'foo',
        foo             => 'actual value',
    },
    ...
])

You need to change that to

$tmpl->param(loopname => [
    {
        
        fixed_key => 'actual value',
    },
    ...
])
[download]

For example by creating a fixed coyp of each hashref like this:

my $new = { fixed_key => $old->{$old->{anothervariable}} };

Consider the case you use DBI to fetch the result of `show tables`, whose keys are in the format `Tables_in_db_name`, there's no way to reduce it into a fixed key, as it changes according to the database name . Is there a better option than copy the whole hash into another one with fixed keys(as obviously this is causing duplicate data)?	[reply] [d/l] [select]

`show tables` just returns one column. You can just do something like `my @loop; while (my @cols = $sth->fetchrow_array) { push @loop, { table_name => $cols[0] }; } $tmp->param(loop => \@loop);` [download] There you go, fixed name (`table_name`) to pass to your template. P.S. if you had provided enough context from the very beginning, it would have been much easier to help you straight away. Perl 6 - second systems done right	[reply] [d/l] [select]

I can't,cause I'm using another encapsulated DB interface which essentially just return the result of `$sth->fetchall_array`. Of course I can blend it again, but it's also bringing overhead,right? Is there a way to do the real nested `TMPL_VAR` thing?	[reply] [d/l] [select]
