Sequel tips & tricks

sequel.rb

# Selecting only column values instead of the whole table
# One column
MyObject.select_map(:column_name) # > [value1, value2, ...]

# Multiple columns
MyObject.select_map([:column1, :column2]) # > [[value1, value2], [value 3, value4], ...]

# And you can have `.where` statements before
MyObject.where(something: true).select_map(:column_name) # > [value1, value2, ...]
