Hi,
I found a problem (and a hackaround solution) with the global search in
Thinking Sphinx.
When I try to use ThinkingSphinx.search(term), I get a traceback like the
following:
NoMethodError: undefined method `constantize' for 0:Fixnum
from lib/thinking_sphinx/search.rb:936:in `class_from_crc'
from lib/thinking_sphinx/search.rb:915:in `instances_from_matches'
from lib/active_support/ordered_hash.rb:139:in `each'
from lib/active_support/ordered_hash.rb:139:in `each'
from lib/thinking_sphinx/search.rb:913:in `instances_from_matches'
from lib/thinking_sphinx/search.rb:436:in `compose_results'
[etc.]
(I cleaned up the pathnames a bit)
My (relevant) environment:
* rails (3.0.9)
* riddle (1.4.0)
* thinking-sphinx (2.0.5 dc98d80)
* sphinx (2.0.1-beta)
I've managed to locate the problem: there are a couple of Sphinx version
number comparisons in ThinkingSphinx::Search, which choose what to do based
on the Sphinx version number. For some reason the correct actions would be
the ones chosen for Sphinx versions < 2, even though I'm running Sphinx
2.0.1.
I can get the search to run correctly with the following monkey-patch:
class ThinkingSphinx::Search
def class_from_crc(crc)
# if Riddle.loaded_version.to_i < 2
config.models_by_crc[crc].constantize
# else
# crc.constantize
# end
end
def crc_attribute
# Riddle.loaded_version.to_i < 2 ? 'class_crc' : 'sphinx_internal_class'
'class_crc'
end
end
Does anybody have an idea of why this is? Does Thinking Sphinx make
incorrect assumptions about the column names returned by sphinx, or do I
have a configuration error somewhere?
