Rails find with a block

Question

I have seen Rails find method taking a block as

Consumer.find do |c|
  c.id == 3
end

Which is similar to Consumer.find(3).

Answer 1

The result may be similar, but the SQL query is not similar to Consumer.find(3)

It is fetching all the consumers and then filtering based on the block. I cant think of a use case where this might be useful

Here is a sample query in the console

 consumer = Consumer.find {|c|c.id == 2}
 # Consumer Load (0.3ms)  SELECT `consumers`.* FROM `consumers`
 # => #
