32651: Float with Float ERROR karşılaştırma başarısız ruby ​​

Question

Raylar için yeni yaşıyorum ve bir hata alıyorum ve sorun olduğunu göremiyorum. İşte günlük geçerli:

ben dosyaya gidip o satır bulmak zaman, hiçbir each yoktur ve sorun nerede olduğunu anlayamıyorum. Biri yardım edebilir mi? Bir düzeltmeden daha fazlası, sorunu anlamak istiyorum. Her iki Şamandıralar biri NaN ise

class Lifetime 
    attr_reader :values 

    GROWTH_CUT_OFF = 0.10 

    def initialize(engaged_users_values) 
    @values = engaged_users_values 
    end 

    def run 
    growths  = growth(values) 

    return [0] if growths.uniq.first == 0 || growths.empty? 

    max_growth = max_growth(growths) 
    dead_growth = least_growth(growths, max_growth) 

    time_diff = time_diff(values.last['end_time'], 
          values.first['end_time']) 
    return [time_diff] unless dead_growth 

    dead_loc  = growths.index(dead_growth) 
    dead_value = values[dead_loc] 
    lifetime(values.first, dead_value) 
    end 

    def time_diff(last, first) 
    in_minutes(parse_time(last)-parse_time(first)) 
    end 

    def parse_time(time) 
    DateTime.parse(time) 
    end 

    def growth(values) 
    values.each_cons(2).map do |one, two| 
     one_value = one['value'].to_f 
     two_value = two['value'] 

     ((two_value-one_value)/(one_value)*100).round(2) 
    end 
    end 

    def max_growth(growths) 
    growths.max 
    end 

    def least_growth(growths, max_growth) 
    growth_cut = growth_cut(max_growth) 
    growths.select {|g| g <= growth_cut}.first 
    end 

    def growth_cut(max_growth) 
    max_growth*GROWTH_CUT_OFF 
    end 

    def lifetime(first_value, last_value) 
    first = parse_time(first_value['end_time']) 
    last = parse_time(last_value['end_time']) 

    result = last-first 
    [in_minutes(result)] 
    end 

    def in_minutes(time) 
    time.to_f*24*60 
    end 
end 

Answer 1

sonra bu mesajı alır: Burada

dosyasıdır. Yani, NaN vakasını önleyin.

hatanın tam kodunu (max_growth yöntemi)
