force_quotes - csv: Ruby Standard Library Documentation

###### Option `force_quotes`¶ ↑

Specifies the boolean that determines whether each output field is to be double-quoted.

Default value:

    CSV::DEFAULT_OPTIONS.fetch(:force_quotes) # => false

For examples in this section:

    ary = ['foo', 0, nil]

Using the default, `false`:

    str = CSV.generate_line(ary)
    str # => "foo,0,\n"

Using `true`:

    str = CSV.generate_line(ary, force_quotes: true)
    str # => "\"foo\",\"0\",\"\"\n"
