QA (public)

please clarify

An example I generate with chatGPT might be a better example. I used _needle_by_id_and_extension
The result was

=head2 _needle_by_id_and_extension

  $self->_needle_by_id_and_extension($extension);

Fetches a needle by its ID and serves a static file with the specified extension.

=over 4

=item *

$self: The object instance (usually a controller object).

=item *

$extension: The file extension to append to the needle's name when constructing the filename.

=back

This method performs the following steps:

=over 4

=item 1.

Checks if the 'needle_id' parameter is present in the request. If not, it returns a 404 Not Found response.

=item 2.

Looks up the needle in the database using the 'needle_id' parameter. If the needle is not found, it returns a 404 Not Found response.

=item 3.

Retrieves the directory path associated with the needle.

=item 4.

Constructs the filename by concatenating the needle's name with the provided extension.

=item 5.

Adds the needle's directory path to the list of static paths.

=item 6.

Serves the static file with the constructed filename.

=back

Returns the result of serving the static file.

=cut

sub _needle_by_id_and_extension ($self, $extension) {
    return $self->reply->not_found unless my $needle_id = $self->param('needle_id');
    return $self->reply->not_found unless my $needle = $self->schema->resultset('Needles')->find($needle_id);

    my $needle_dir = $needle->directory->path;
    my $needle_filename = $needle->name . $extension;

    push @{$self->static->paths}, $needle_dir;
    return $self->_serve_static($needle_filename);
}

Closing due to no response.
