How can I create a column that is of the same type as a column in some
other table?
I am using: DB.schema(another) table to retrieve field type:
def type_of_field(field_name)
field_name = field_name.to_sym
f = @connection.schema(@table_name).detect { |f| f[0] ==
field_name }
if f
return f[1][:type]
end
return nil
end
and then I use it in:
field_type = type_of_field(field)
@connection.create_table(some_other_table) do
....
column field, field_type
....
end
For some types it does not work, such as text in Postgres which will
be :string in Sequel and then string back in Postgres - which is
undefined:
PGError: ERROR: type "string" does not exist
Is there any way how to achieve this? At least within single database
adapter (for example - original, non-converted column type name would
help).
Thanks,
Stefan
