Follwoing मेरी GemFile है this, लेकिन इससे मुझे मदद नहीं मिली है। हर जगह मुझे केवल यह समाधान मिला। क्या कोई इससे पहले इस मुद्दे पर आया है, यदि हां, तो इससे निपटने के लिए आपने क्या किया? इस पर किसी भी मदद की सराहना की जाएगी। धन्यवाद
धन्यवाद आदमी। यह काम कर रहा है। यह वही मुद्दा था, माइग्रेशन फ़ाइल में विधि नाम बनाने के बजाय कॉलम नाम थे। – lucifer
क्या आप इस उत्तर में माइग्रेशन कोड डाल सकते हैं। – baash05
