itsthekrnguy What is the significance of |user|?
benj2240Asked to answer Endorsed by itsthekrnguyThat binds each element of the list to the variable name user. Here is some equivalent code, in a less "Ruby" style.
i = 0 while i < array.size user = array[i] # do stuff i += 1 end
itsthekrnguy Ah I see, thank you for clarifying!
brady_benjamin_r I did
def scoring(array) array.each(&:update_score) enddanielgcwik thanks that did work
arvindvyas07 def scoring(array) array.map(&:update_score) end
aiswarya110498 this is the exact answer:
def scoring(array)
array.each do |user|
user.update_score
end
iterate through each of the element in array using each and call update_score on it
end
phillipr360 Can we see the source code for User? As well as how the array is defined/populated initially?
Without it, it's just another blind "copy and paste, have blind faith that everything works as expected" problem.
malrefai array.each {|user| user.update_score}
dvt32 I used a block instead (thanks, CodeCademy!):
def scoring(array) array.each { |user| user.update_score } end
harishankardewa error ?

harishankardewa I am typing this yet getting this error...->->
array.each do |user|
user.update_score
soccerob you need an "end" for your .each enumeration
array.each do |user|
user.update_score
end
harishankardewa thanx !! :D
i5pranay my code is not running.
def scoring(array)
array.each do |user| User.update_score endend
barmvicente the instruction is casesensitive, user should be lowercase.
kumar33manish Replace User with user

sinhasagar01Asked to answer you don't have to pass any arguments here. array.each do |user| user.update_score your code should be this
muggie23 Getting error "in
block in scoring': undefined methodupdate_score' for User:Class (NoMethodError)"
aniruddha_nitb Don't put '?' after update_score user.update_score
RangerDanger You have to call the method on an object. I was getting this error, when I was callin the method with no object.
ex. obj.method
