Multiple conditions on single attribute?

Reported by Marcel Ruegenberg | February 11th, 2009 @ 07:10 AM

Is it possible to have multiple conditions on a single attribute?


search = User.new_search
search.conditions.name_like = "Foo"
search.conditions.or_name_like = "Bar"

Currently, this only uses one of the two conditions, it generates something like


... WHERE name LIKE "Foo"

instead of joining the two conditions with OR.

My current workaround is to use groups:


search = User.new_search
search.conditions.group do |group|
  group.or_group do |group|
    group.name_like = "Foo"
  end
  group.or_group do |group|
    group.name_like = "Bar"
  end
end

This works, but is kind of verbose...

    Yes, you need to pass it an array of values. So:

    search.conditions.name_like = ["Foo", "Bar"]
    

    Hope this helps.

    The grouping with the array of values works allright, but they are joined by an AND...

    
    search.conditions.name_like = ["Foo", "Bar"] 
    

    would result in something like

    
    ... AND (name LIKE '%FOO%' AND name LIKE '%Bar%')...
    

    which obviously is never what we want.

    Adding the line

    
    self.join_arrays_with_or = true
    

    to condition/like.rb fixes this for me.
