डेविस और रेल - डेविस में ArgumentError :: रजिस्ट्रेशन नियंत्रक #

Question

जब कोई नया उपयोगकर्ता एक नया उपयोगकर्ता पंजीकरण फॉर्म सबमिट करता है तो उन्हें नीचे त्रुटि संदेश मिलता है। मुझे संदेह है क्योंकि devise/registrations_controller.rb मौजूद नहीं है।

क्या मुझे इस फ़ोल्डर संरचना और नियंत्रक को बनाने की आवश्यकता है या क्या मैं मौजूदा अस्तित्व नियंत्रक की खोज से बचने के लिए मार्ग.आरबी संशोधित कर सकता हूं?

त्रुटि:

ArgumentError in Devise::RegistrationsController#create 

wrong number of arguments (0 for 1) 
Rails.root: C:/Users/COMPAQ/Documents/NetBeansProjects/RailsBlog 

Parameters:

    "user"=>{"email"=>"foo@bar.com",

ट्रेस वापस - मैं एक नज़र पड़ा है लेकिन यह पता नहीं कर सकते हैं जहां मुद्दा झूठ है:

Answer 1

Devise::RegistrationsControllerwithin the Devise gem मौजूद है, इसलिए आपको इसे बनाने की आवश्यकता नहीं है।

अद्यतन: त्रुटि तब होती है क्योंकि आप has_secure_password है, जो घर का बना प्रमाणीकरण समाधान के लिए है का उपयोग कर रहे हैं। आपको डेविस के साथ इसकी आवश्यकता नहीं है (यह पासवर्ड की एन्क्रिप्शन को ही संभालती है)। उस रेखा से छुटकारा पाएं!

आपके ऐप को उड़ाने का कारण यह है कि यह आपके मॉडल पर एक विशेषता होने के लिए password_digest की अपेक्षा करता है, और validates its presence। जब यह सत्यापन करता है, तो यह विशेषता को पढ़ने की कोशिश करता है, लेकिन इसके बजाय यह क्या होता है, डेविस की password_digest विधि (जो पासवर्ड को तर्क के रूप में प्राप्त करने की अपेक्षा करता है, इसलिए ArgumentError उठाता है जब इसे प्राप्त नहीं होता है)।
