How to Fix Undefined Method 'Split' for Nil:Nilclass Error

How to fix undefined method `split' for nil:NilClass error?

A possible solution would be to use try which does return nil in case your method cannot be sent to secondary_images. And then use the OR-operator to assign something else.

@images = @product.secondary_images.try(:split, ",") || 'some other value'  

undefined method `split' for nil:NilClass (NoMethodError) for an array

Obviously while i<lnth not <=:

while i<lnth
  size = input[i].split(/\s/).map(&:to_i)
  i=i+1
end

but preferably use:

size = line.split(/\s/).map(&:to_i)

undefined method `split' for nil:NilClass within Rails

The problem is here:

CGI.parse(uri.query)

The uri.query is nil and the parse method tries to split it.

If you want to return nil when the value is not present, replace the line with:

CGI.parse(uri.query).try(:[], 'v') if uri.query

Undefined method .split for Nil class Ruby

If replaced by search_method = "calc_#{input}".to_sym also works.

Helped add def initialize @books end.

Instead of contents = send (search_method, @books) you can use send (search_method, @books).

require "colorize"

class Filecalculation

    def initialize
        @books = "You can use this knowledge to create small tools that might help you."
    end

    def calc_1 paragraph            
        word_count = paragraph.strip.squeeze(' ').count(' ') + 1  
        puts "#{word_count} words"   
    end

    def select

        loop do
            puts "# Will we search : Calculation_lines paragraph(1)".cyan
            print "\n>>>>>> ".yellow
            input = gets.chomp
            search_method = "calc_#{input}" #.to_sym

            if (respond_to?(search_method))
                contents = send(search_method, @books)
            else
                puts "exit "
                exit
            end
       end 
    end
end

Filecalculation.new.select

Ruby exception occurred: undefined method `split' for nil:NilClass

I should test the value before using it.
So that I changed the code to this:

ruby {
        code => 'urls = event.get("[request_url]")
                 if urls
                        separated = urls.split("/")
                        if separated
                                separated.each_index {|x|
                                        temp = "P" + x.to_s
                                        event.set(temp,  separated[x])
                                }
                        end
                 end'
    }

and the error fixed.

NoMethodError: undefined method `split' for nil:NilClass when deploying with Capistrano

This is a documented problem with the rollbar gem.

https://github.com/rollbar/rollbar-gem/issues/411

Update the gem with bundle update rollbar

undefined method 'split' for nil:NilClass (NoMethodError)

It's telling you that name is nil, probably because row[1] doesn't exist. My guess is the columns aren't being split properly. Right now you're saying that columns are separated by tabs but that's not what the screenshot is showing.

Are you sure you don't want :col_sep => ","?
