rails active record - complicated conditions clause
this works:
ids = [1,2]
varietals = Varietal.find(:all, :conditions => [ "id IN (?)",ids])
But what I want to do is that plus have a condition of: deleted => false
varietals = Varietal.find(:all, :co开发者_C百科nditions =>{ :deleted => false})
any ideas?
am i going to have to use find_by_sql?
I would handle this with a named_scope to communicate intent and foster re-use:
named_scope :undeleted,
:conditions => { :deleted => false }
Then you can simply use:
varietals = Varietal.undeleted.find([1,2])
You can do it a few ways, but this is the most straight forward:
varietals = Varietal.find( [1,2], :conditions => { :deleted => false })
You can see in the docs that the first parameter of find
can take an integer or an array.
ids = [1,2]
varietals = Varietal.find(:all, :conditions => {:id => ids, :deleted => false})
This should work, haven't tested it though.
From the docs:
An array may be used in the hash to use the SQL IN operator:
Student.find(:all, :conditions => { :grade => [9,11,12] })
