Had this working until I refactored by putting into a hash and checking
for blank. Now I get the error: undefined method `key?'' for
nil:NilClass.
I''m still kind of new at this and would appreciate suggestions on what
I
am missing...
before_validation :capitalize_first_words
def capitalize_first_words
[:question, :correct_ans_1, :correct_ans_2, :correct_ans_3].each
do |key|
self.key = self.key.gsub(/^(\W*?[a-z])/) { |m| m.upcase } if
self.key != blank
end
end
Thanks,
Dave

Now giving error:
undefined method `key'' for #<Question:0x007fdff26b7798>
In Question model:
before_validation :capitalize_first_words
def capitalize_first_words
[:question, :correct_ans_1, :correct_ans_2, :correct_ans_3].each
do |key|
self.key = self.key.gsub(/^(\W*?[a-z])/) { |m| m.upcase } if
!self.key.blank?
end
end
Am I missing something really quite simple?
Thanks

before_validation :capitalize_first_words
def capitalize_first_words
[:question, :correct_ans_1, :correct_ans_2, :correct_ans_3].each do
|key|
self.key = key.to_s.gsub(/^(\W*?[a-z])/) { |m| m.upcase } if
!key.to_s.blank?
end
end
Note the difference betweet self.key and key.
self.key calls method key on self.
key - is block local variable, which is instance of Symbol ( :question,
:correct_ans_1 ...).
Symbol has not methods ''.gsub'' and
''.blank?'', so it must be converted to
String to call ''.gsub'' and ''.blank?''

But, even the following causes error: undefined method `key='' for
#<Question:0x007fcba5972f20>
before_validation :capitalize_first_words
def capitalize_first_words
[:question, :correct_ans_1, :correct_ans_2].each do|key|
self.key = "x"
end
end
key is still not being interpreted as "question" or
"correct_ans_1",
ect...
Could it be a scope issue? I am in the Question model.

But your instinct is correct, key isn''t being evaluated before it is passed to the self reference, so you''re still looking for a key method that isn''t there.> end > end > > key is still not being interpreted as "question" or "correct_ans_1", > ect... > Could it be a scope issue?

Instance of Question doesn''t have attribute "key". If this is ActiveRecord, you maybe should make migration "add_column :questions, :key, :string", OR within class scope write "attr_accessor :key" среда, 4 сентября 2013 г., 15:17:47 UTC+3 пользователь Ruby-Forum.com User написал:> > But, even the following causes error: undefined method `key='' for > #<Question:0x007fcba5972f20> > > before_validation :capitalize_first_words > > def capitalize_first_words > [:question, :correct_ans_1, :correct_ans_2].each do|key| > self.key = "x" > end > end > > key is still not being interpreted as "question" or "correct_ans_1", > ect... > Could it be a scope issue?

The instance of Question should have the attribute contained in the variable... It just doesn''t seem to be evaluating key. I''m sure i''m missing something simple... Any other possibilities?
