Rails: Has many through associations — find with AND condition, not OR condition

Question

I have the following query method in my ActiveRecord model:

def self.tagged_with( string )
    array = string.split(\',\').map{ |s| s.lstrip }
    select(\'disti         


        

Answer 1

You could change your select statement to the following:

select('distinct photos.*').joins(:tags).where('tags.name = ?',  array.join(' OR '))

Which will properly create the OR string in the where clause.
