Really simple object relational mapping for CSV spreadsheets. Loads all data into a ruby array first so not appropriate for very large datasets. However, it's just as fast as working with a 2d ruby array, so it's very fast for reasonably sized datasets.
Add this line to your application's Gemfile:
gem 'csvdb'And then execute:
$ bundle
Or install it yourself as:
$ gem install csvdb
table = Csvdb.new(file: 'table.csv')
table.cols.keys #=> [:id, :name] The table headings (from row[0] in file)
table.create(
id: 1, name: 'foobar'
) #=> [1, 'foobar'] Newly created row
row = table.find(0) #=> [1, 'foobar'] find by index in array
row.id #=> 1
row.update(id: 2) #=> [2, 'foobar']
row.delete
row.find(0) #=> niltable = Csvdv.new(file: 'table.csv')
table.count #=> 5
# queries always return new table objects, with the same headings,
# just filtered by the block
query = table.where { |row| row[table.id] == 1 }
query.count #=> 1
# joins also always return table objects.
joined = table.join(another_table, col1: :table_col, col2: :another_table_col)table = Csvdb.new(file: 'table.csv')
table.pretty
