Alternative for bignum for primary key in ruby sequel

Since sequel 4.xx this code:

Sequel.migration do
  up do
    create_table :rate do
      primary_key :id, :type => Bignum
      ...    
      end  
  end
...
end

throws an error Sequel::Error: Unsupported ruby class used as database type: Bignum So, what is the alternative if I want to create PK using big integer?
I use ruby 2.2 and postgresql 9.5.

Solution

  • Using Bignum (the class) as a generic type was removed as it would break in ruby 2.4 as Bignum is Integer in ruby 2.4. Use :Bignum (the symbol) instead for a generic 64-bit integer type.
