find_by_contents will fail if you specify :include in the find_options
parameter. The problem is on line 313:
313: conditions = [ “id in (?)”, id_array ]
314: # combine our conditions with those given by user, if any
315: if find_options[:conditions]
316: cust_opts = find_options[:conditions].dup
317: conditions.first << " and " << cust_opts.shift
318: conditions.concat(cust_opts)
319: end
320: result = self.find(:all,
321: find_options.merge(:conditions => conditions))
Since the id field will be present in two separate tables, it will be
ambiguous and throw an exception, e.g.
Question Load Including Associations (0.000000) Mysql::Error: Column
‘id’ in where clause is ambiguous: SELECT foos.id AS t0_r0, …
bars.id AS t1_r0, … FROM foos LEFT OUTER JOIN bars ON bars.foo_id =
foos.id WHERE (id in (1))
REBUILD YOUR INDEX! One of the id’s didn’t have an associated record: 1
Error should probably log a better message too…
Quick way to fix it:
313: conditions = [ “#{table_name}.#{connection.quote_column_name(‘id’)}
in (?)”, id_array ]
I don’t know if it’s the perfect fix, but it works for me.
