मैंने उपयोगकर्ता मॉडल को बढ़ाया और उपयोगकर्ताओं से ग्राहक मॉडल में एक से एक संबंध बनाया। हालांकि, जब भी मैं ग्राहक पृष्ठ को कॉल कर रहा हूं तो उपयोगकर्ता मॉडल के फ़ील्ड वहां प्रस्तुत नहीं किए जाते हैं। यह पहले नाम को नाम, अंतिम नाम और ईमेल पते के रूप में प्रस्तुत करने के बजाय केवल एक फ़ील्ड, फ़ील्ड नाम में ग्राहक मॉडल में उपयोगकर्ता नाम प्रदान कर रहा है, और इसी तरह। मैं उसे कैसे प्राप्त कर सकता हूं? मुझे उपयोगकर्ता के पंजीकरण से जो भी उपलब्ध हो, जानकारी का उपयोग करके भरने के लिए ग्राहक प्रपत्र की आवश्यकता है। समझ में आता है? या मैं जो कार्यान्वयन करने की कोशिश कर रहा हूं वह गलत है। पहले ही, आपका बहुत धन्यवाद। कृपया Model.py और views.py के लिए कोड नीचे देखें
