"wrong number of bind variables (1 for 2) in ....

[atif]

I am facing the above exception. I've defined a composite index that includes a boolean column and it's not working. Does anyone has an idea what's the problem?

You have a find with :conditions somewhere that needs two bind variables, but you're providing one.

Is this in your app, or is it a cache-money issue?

I have find with condition containing and between three columns like
:conditions => ["A = ? and B = ? and C = ?", "a", "b", true]
I have defined a combined index like
index [:A, :B, :C]

I'm getting this exception only in case of boolean column which in current case is C.
