Description Aleisha Amohia 2017-01-13 00:56:06 UTC
This error:
Undefined subroutine &CGI::Compile::ROOT::home_vagrant_kohaclone_opac_opac_2dreadingrecord_2epl::image_url called at /home/vagrant/kohaclone/opac/opac-readingrecord.pl line 125.
is triggered when I enable BakerTaylorEnabled and look at my reading history on the OPAC because subroutines it needs aren't imported until after they are called.

Aleisha,

I agree that there is something wrong, but the test plan is not enough.

There are several things wrong:
- import must be done at the beginning of the module
- import must not be dependent of syspref in begin blocks

What's happening is that Plack runs all BEGIN blocks when it starts, and that is the only time they are evaluated.
That means that if you start plack with the pref BakerTaylorEnabled disabled, the require+import will not be done.
Then if you enable the pref (and not restart plack of course) and access the opac-readingrec view, it will explode.

Also fix template to use Koha.Preference instead of passing it from the
pl file
