Question

के साथ रेल 3.2 में परीक्षण डेटाबेस नहीं बना सकता है यह एक बेहद अजीब है। इम एक सरल rake db:test:clone करते हैं या बनाने का प्रयास करते हैं और कोई फर्क नहीं पड़ता कि मैं क्या database.yml कॉन्फ़िगरेशन के सभी प्रकार की कोशिश कर रहा करने के लिए gemset समाशोधन से करते हैं, इम oddest त्रुटि मिल रही है:

LINE 1: CREATE DATABASE "tdt_test"0.0 

क्या कभी किसी ने इस तरह कुछ भी देखा गया है पहले? डब्ल्यूटीएफ यह है कि "0.0 !?" मैं रेल 3.2, आरएसपीसी और पीजी मणि 0.14.1
