I am getting this in my error list :
@error_messages = {
:password=>["can't be blank", "Password is required."],
:"addresses.firstname"=>["can't be blank","Firstname is required."],
:"addresses.city"=>["can't be blank", "city is required."]
}
Here I want to remove the value "can't be blank" value from this hash so that I will get the validation error messages which was included by me.
is it possible to remove "can't be blank" value from above hash list and I will get this in result :
@error_messages = {
:password=>["Password is required."],
:"addresses.firstname"=>["Firstname is required."],
:"addresses.city"=>["city is required."]
}
How to remove a specific value from a hash list(want to remove a specific value not a complete key,value pair).
Yes, possible.
@error_messages = {
:password=>["can't be blank", "Password is required."],
:"addresses.firstname"=>["can't be blank","Firstname is required."],
:"addresses.city"=>["can't be blank", "city is required."]
}
@error_messages.each do |_,v|
v.delete( "can't be blank" )
end
@error_messages
# => {:password=>["Password is required."],
# :"addresses.firstname"=>["Firstname is required."],
# :"addresses.city"=>["city is required."]}
