hi, i created a validation to prevent users to write text uppercase in
my fields, i have writing the code on my class model like this:
#####################
validate :detect_uppercase_title, :detect_uppercase_description
private
#prevent users to write text uppercase, and reset field text to
lowercase
def detect_uppercase_title
size_letters = title.scan(/\w/).size
size_invalid = title.scan(/[A-Z]/).size
if size_invalid > 0
if (size_letters / size_invalid) < 4 and size_letters > 10
errors.add( :title,
I18n.t('activerecord.errors.messages.uppercase'))
write_attribute(:title, title.downcase)
end
end
end
def detect_uppercase_description
size_letters = description.scan(/\w/).size
size_invalid = description.scan(/[A-Z]/).size
if size_invalid > 0
if (size_letters / size_invalid) < 4 and size_letters > 10
errors.add( :description,
I18n.t('activerecord.errors.messages.uppercase'))
write_attribute(:description, description.downcase)
end
end
end
#####################
but now i want to define a function to doing this without repeating and
make more DRY the code.
i have tried with this:
#####################
validate detect_uppercase(title), detect_uppercase(description)
private
def detect_uppercase(field)
size_letters = field.scan(/\w/).size
size_invalid = field.scan(/[A-Z]/).size
if size_invalid > 0
if (size_letters / size_invalid) < 4 and size_letters > 10
errors.add( field,
I18n.t('activerecord.errors.messages.uppercase'))
write_attribute(field, field.downcase)
end
end
end
#####################
but i see it not work.
hw can i do to implement my necessity?
