Catalyst::View::Mason and Exception objects
|
|
The following Mason template:
<%init>
die;
</%init>
results in a typical Catalyst error response.
This, on the other hand:
<%init>
DBIx::Class::Exception->throw('Foo');
</%init>
just gives a plain-text output, and the request is recorded as a success
($c->error is not set, finalize_error is not called, plugins like
ErrorCatcher are never triggered).
The issue seems to lie here:
174 if (blessed($output) && $output->isa('HTML::Mason::Exception')) {
175 chomp $output;
176 my $error = qq/Couldn't render component "$component_path" -
error was "$output"/;
177 $c->log->error($error);
178 $c->error($error);
179 return 0;
180 }
Since Mason does not wrap exception objects but simply re-throws them, the
exception object gets here and bypasses this.
More interesting is that this actually appears to be intentional behavior --
the View::Mason distro actually tests for it in t/exception.t. Any ideas on
why it's handled this way and how to make it DWIM?
