QUESTION
I have a bunch of DBIx::Class Result classes created from my database schema by dbicdump / DBIx::Class::Schema::Loader
I need to add an is_deleted
boolean column to one of the tables, and to filter out deleted records in all the existing searches and JOINs.
Unfortunately there are 30 or 40 places in the sprawling perl app which directly use the table in question, and at least the same number of places which JOIN to it via prefetch
or join
attributes to search()
. Changing them all manually is possible, but very time consuming.
Is there a way to add a default WHERE
clause to all queries which SELECT
from or JOIN
to a particular table?
I'm after some way to be able to call resultset('MyTable')->search({},{})
and have WHERE is_deleted = 0
added to all the queries.
Plus have the same is_deleted = 0
filter applied when prefetch => [qw(my_table)],
is used.

method to add your search criteria.
QUESTION
I am trying to connect to a database using perl. I tried to follow this tutorial https://metacpan.org/pod/release/RIBASUSHI/DBIx-Class-0.082840/lib/DBIx/Class.pod and create a simple app named MyApp as they made and create the files exactly as they did but when I compile the CD.pm file I am getting the error Can't locate MyApp/Schema.pm in @INC (you may need to install the MyApp::Schema module).
The program is looking like that in Atom using package Script to run the code on ubuntu:

If that's the case, then I really think that building an application that uses DBIx::Class is a bit of a stretch for your first attempt. I'd recommend spending some time getting to grips with writing command-line programs with Perl first.
But that might not be possible. In which case, read on...
You haven't given us the full error message that you're getting (and, for future reference, that would have been really useful) but I suspect that it goes on to tell you the list of directories that are currently in @INC
.
When Perl loads a module, it needs to know where it might find the file that contains that module. It does that by using a special array variable called @INC
. @INC
contains a list of all of the directories that Perl should search to find module code. There are a number of directories that are "baked-in" to your Perl installation when it is set up, but there are various ways to add to that list.
Your error message will have given you the current list of directories in @INC
, but you can also get it from this simple command-line Perl program:

I'd named the pipeline job TestProject(pipeline)

Job name contains parentheses, so does the name of workspace directory, and BOOM inside a shell command...
