Answer 1

इस रेल 4. तुम क्यों इस तरह के एक पुराने वसीयतनामा संस्करण का उपयोग कर रहे हैं में एक नया जांच है (और क्यों एक आर सी?)। बस जब रेल के पिछले संस्करण से उन्नत करने के लिए 4.0.0 रेल की कोशिश कर अपने Gemfile

Answer 2

ArgumentError: The provided regular expression is using multiline anchors (^ or $), 
which may present a security risk. Did you mean to use \A and \z, 
or forgot to add the :multiline => true option? 

यह त्रुटि आती है में

gem "devise", "~> 3.0.3" 

रखकर सबसे हाल ही में रिलीज का उपयोग करें।

validates_format_of के लिए Regexp सत्यापन।
यदि आप मल्टीलाइन आने वाले डेटा की अपेक्षा नहीं करते हैं, तो आपको सभी "^" को "\ A" और "$" के साथ "\ z" के साथ बदलना होगा। यदि आप मल्टीलाइन स्ट्रिंग की अपेक्षा करते हैं, तो बस मल्टीलाइन: सही विकल्प निर्दिष्ट करें।

स्रोत: http://dev.mensfeld.pl/2013/07/upgrading-to-rails-4-0-from-rails-3-2-test-case-part-ii-assets-models/

अपने त्रुटि के लिए विशेष कारण के बारे में सुनिश्चित नहीं है, लेकिन मैं नवीनतम संस्करण जो रेल 4.0.0 का समर्थन करता है के लिए वसीयत को अद्यतन करने की कोशिश करेंगे।

Answer 3

^$ और $ मैचों के बाद से $ $ का उपयोग करना सुरक्षित नहीं है (नई लाइन विशेषता है) जिसमें "test123@example.com \ n < स्क्रिप्ट>/* जैसे ईमेल दर्ज करने की संभावना है ... */</script> "

http://edgeguides.rubyonrails.org/active_record_validations.html#format

तो अगर हम का उपयोग^और $ अंत या एक अभिव्यक्ति की शुरुआत मैच के लिए तो ऊपर दिए गए ईमेल के साथ में पारित किया जा सकता है और किसी भी फिल्टर दुर्भावनापूर्ण कोड से पारित होने की संभावना है घुसा।

हम/ए,/Z विकल्प का उपयोग कर सकते हैं या तो शुरूआत है और एक पंक्ति के अंत specfy करने के बजाए^और $, वरना हम सेट कर सकते हैं: सच

जैसे करने के लिए बहु विकल्प: सत्यापन करती है: सामग्री, प्रारूप: {साथ:/^ इस बीच $ /, बहु: सच}
