Question on an exception; seems related to autocrud?

Hi all,

I'm working on a Catalyst app; currently in the early stages. I'm also
learning the framework, so this may be a beginner question.

I started this app by defining the database tables, then creating a .sql
file, and using that to import to sqlite3 (I was following along in the
tutorial, for the most part). To verify everything was working, I added
autocrud, so I could watch the changes as I made them, including doing
some INSERTs to pre-populate the tables. Nothing fancy.

Then I create a "list" page (similar to "books/list", although in my
case it's "builds/list"), updated the code to extract "all" (builds
instead of books), and tested it. It worked fine, or so I thought; each
time I tested it, I first went to the autocrud page to verify the data,
and then loaded the list page.

Today, I restarted the server and then tried refreshing the
"builds/list" page. I got an exception, with lots of output. Rather
than including the entire output here, I'll just say that it started
with the following, which is what leads me to believe it's somehow
related to autocrud (and the other evidence that reloading any of the
autocrud pages makes the "builds/list" page work again).

Caught exception in SubmitBuild::View::AutoCRUD::JSON->process "must
provide object to convert at C:/Perl/site/lib/Catalyst/View/JSON.pm line
43"

Please let me know if the rest of the output (or a specific portion of
it) would help in determining the root cause.

Thanks,

Just a note, but the full stack trace is usually what is needed for
people to properly diagnose a problem. If you feel it is unusually
long, you can also take advantage of one of the nopaste servers, a gist
at github, or host a text file somewhere. Then just provide a link into
your email.

RE: Question on an exception; seems related to autocrud? [In reply to]

Thanks Nick. I have determined that removing AutoCRUD from the
<project>\lib\<project>.pm file eliminates this behavior, so it seems to
be just a side-effect of having AutoCRUD enabled. Since I won't deploy
with it enabled, it's just something to watch out for in my testing.

To the list: has anyone else noticed a similar difference in behavior
accessing SQLite3 databases from Catalyst, after adding AutoCRUD?

Thanks,
Ken

Hi Ken,

I'm sorry for having missed this message originally, only finding it

This is a little surprising, only because AutoCRUD uses SQLite in
its own test suite.

Having said that, each database does have its quirks so there could
be some issue I've not yet encountered. If this remains a problem
for you, please do send an email to
<bug-Catalyst-Plugin-AutoCRUD [at] rt> and we can look at this
in more depth.

regards,
oliver.
