Tagged with, wildcard

[CucumisSativus]

I have an issue with using tagged_with with wildcard. Calling it with a full name of a tag works great, but with only a part it does not. I decided to inspect it.

Company.tagged_with('zdrowa żywność', wild: true)
  ActsAsTaggableOn::Tag Load (0.5ms)  SELECT "tags".* FROM "tags"  WHERE (LOWER(name) = LOWER('zdrowa żywność'))
  Company Load (0.8ms)  SELECT "companies".* FROM "companies" JOIN taggings companies_taggings_caa133f  ON companies_taggings_caa133f.taggable_id = "companies".id AND companies_taggings_caa133f.taggable_type = 'Company' AND companies_taggings_caa133f.tag_id = 128 WHERE "companies"."removed" = 'f'
 => #<ActiveRecord::Relation [#<Company id: 14, (...)]>]>

As I mentioned this one is ok, but calling it with only a part of a name should return at least one record but it does not.

Company.tagged_with('zdrowa', wild: true)
  ActsAsTaggableOn::Tag Load (0.5ms)  SELECT "tags".* FROM "tags"  WHERE (LOWER(name) = LOWER('zdrowa'))
  Company Load (0.4ms)  SELECT "companies".* FROM "companies"  WHERE "companies"."removed" = 'f' AND (1 = 0)
 => #<ActiveRecord::Relation []>

Inspecting it deeper

Company.tagged_with('zdrowa', wild: true).to_sql
  ActsAsTaggableOn::Tag Load (0.6ms)  SELECT "tags".* FROM "tags"  WHERE (LOWER(name) = LOWER('zdrowa'))
 => "SELECT \"companies\".* FROM \"companies\"  WHERE \"companies\".\"removed\" = 'f' AND (1 = 0)"

Is there any logical explanation for AND (1 = 0) at the end of query?

My environment:
rails (4.1.4)
acts-as-taggable-on (3.3.0), from ruby-gems
ruby 2.1.2p95 (2014-05-08 revision 45877) [x86_64-darwin13.0]

Congratulations, you found an Easter egg in the gem.

It's a bug, i will fix it.
As workaround put the tags into a array Company.tagged_with(['zdrowa'], wild: true).to_sql

Unfortunately, not this time

Company.tagged_with(['zdrowa'], wild: true).to_sql
  ActsAsTaggableOn::Tag Load (0.7ms)  SELECT "tags".* FROM "tags"  WHERE (LOWER(name) = LOWER('zdrowa'))
 => "SELECT \"companies\".* FROM \"companies\"  WHERE \"companies\".\"removed\" = 'f' AND (1 = 0)"

hmm

TaggableModel.tagged_with(['bob'], wild: true).to_sql
"SELECT \"taggable_models\".* FROM \"taggable_models\" JOIN taggings taggable_mod_taggings_5ce8fb5  ON taggable_mod_taggings_5ce8fb5.taggable_id = taggable_models.id AND taggable_mod_taggings_5ce8fb5.taggable_type = 'TaggableModel' AND taggable_mod_taggings_5ce8fb5.tag_id = 1"

Do you have a default scope ?

[CucumisSativus]

Only on Company model

default_scope { where(removed: false) }

[seuros]

add 'any: true'

Thanks, that workaround works

better to state this on the readme. Thanks.
