Rails tests fail because ferret index is not updated when starting tests

that's exactly what aaf does - it creates it's index directories in RAILS_ROOT/index/RAILS_ENV/ by default. If this doesn't work for you I'd need some more information to find out why.

closing

It puts the indexes in RAILS_ROOT/index/RAILS_ENV/ but it does not clear the index before each test method.

I have two functional tests. One deletes a fixture, the other does a search which should return that fixture.

Running either test separately is fine, but if I run them together, with the search being the second one, it fails because the index was not reset between the two tests.

It would be hard to guess for aaf when to rebuild the index in such a scenario. Just put the appropriate rebuild_index calls in your test's setup method:

def setup
  Model.rebuild_index
end

Or you could even wipe out the whole index/test directory like that:

require 'fileutils'

def setup
  FileUtils.rm_f "#{RAILS_ROOT}/index/test/"
end

In either case the index will be rebuilt from your fixtures before each test method is run. Does that solve your problem?

I tried FileUtils?.rm_rf. The strange thing there was the directory was removed, but it was never subsequently rebuilt upon the find_by_contents call, causing an error.

What I ended up doing was to add a class method I found elsewhere in a comment here to the model and call it before the search tests:

def self.zero_index

index = self.ferret_index index.size.times {|i| index.delete(i)}

end

Perhaps rebuild_index does the same thing?

I am seeing the same behaviour during testing.

I have some functional test methods that are exercising an EventController?, but aaf is not re-indexing. The problem started happening when I introduced a test_destroy method (which tests deletion of an Event object from the db). Because tests seem to get run in alphabetical order, and test_show occurs after test_destroy, I get an exception during test_show because the index was not rebuilt:

Exception: cannot determine document number from primary key: 1

I think this happens because the "show" page in my app has a more_like_this method call which can't complete due to an indexing problem.

Putting Event.rebuild_index in setup doesn't help, I get:

Exception: File Not Found Error occured at <except.c>:117 in xpop_context
Error occured in fs_store.c:329 - fs_open_input
	tried to open "/home/yossa/workspace/railsapp/config/../index/test/event/_3_1.del" but it doesn't exist: <No such file or directory>

The FileUtils?.rm_f idea doesn't seem to be working either.

The quickest dumbest hack for now would be to rename test_show to something like test_a_show so that it executes before the test_destroy method.

I also tried introducing a zero_index method in Event, but that didn't seem to work for me.

I was having a similar problem. I have transactional fixtures turned off if that affects things. The errors I was seeing was because some objects weren't getting saved to the DB because the :ferret_create callback was failing. The exception that was raised was similar to the previous comment:

#<Ferret::FileNotFoundError: File Not Found Error occured at <except.c>:117 in xpop_context
Error occured in fs_store.c:329 - fs_open_input
        tried to open "...../index/test/model/_o.cfs" but it doesn't exist: <No such file or directory>

I tried this (reload fixtures drops all the data from all the fixture tables then reloads it, so you end up with records in test 2 having different ids than test 1):

def setup
  reload_fixtures
  Model.rebuild_index
end

but it didn't help. I still got the same exception. I then tried:

  def setup
    reload_fixtures
    FileUtils.rm_r("#{RAILS_ROOT}/index/#{RAILS_ENV}") if File.directory?("#{RAILS_ROOT}/index/#{RAILS_ENV}")
  end

and it appears to work.

Why wouldn't calling rebuild_index work?

I forgot to add to my last ticket that I stepped through the AAf ruby code until I got to:

/var/lib/gems/1.8/gems/ferret-0.11.4/lib/ferret/index.rb:285
@writer.delete(@key, id)

That's the line that raised the File Not Found error. Here's the stack trace from when I called 'save' on my model instance.

Can anybody please provide a unit or functional test that reproduces this behaviour within aaf's demo project?

to resolve the errors when using rm_rf, close the ferret index before:

Model.aaf_index.close
