This is only happens in TESTING environment.

The record never shows up in the DB either. Why is rails lying to me?

Hi Dan,

p is actually a method in Ruby. So, p() returns nil, and p.id means
the id() on nil. :slight_smile:

Use the names of your variables carefully :slight_smile: I wolud definitely avoid
names p, as well as methods/fields with name id.

Thanks,
–Vladimir

Vlad,
Are you sure on this?

From looking at the steps taken and applying your logic the p.save and
others should return method missing then. Wouldn’t it?

When I run the above example in MRI and JRuby dev branch I get
expected behavior. (p.id works) Dan can you try an example with the
latest JRuby and see if the problem is fixed?

Well, maybe not 100% sure :slight_smile: But every time I used p as a name for a
variable, sooner or later I got burned one way or another (weird
things like described in this thread), so I just don’t do that
anymore. Especially in jirb! :slight_smile:
