रेक db: दे रही है 'अप्रत्याशित \ N' त्रुटि

Question

मैं Rails scaffolding इस्तेमाल किया एक मॉडल टर्मिनल से आदेश का उपयोग करने के लिए विस्थापित:

rails generate scaffold Venue venueid:string, venueName:string, venueAddress:string, venueCity:string, venueState:string, venueZip:integer, venuePhone:string, venueAge:int 

सब कुछ स्थापित करने या ठीक उत्पन्न करने के लिए लगता है, लेकिन मैं मिलता है जब मैं rake db:migrate चलाने निम्न त्रुटि:

rake aborted! 
/Users/Banderson/Documents/demo/db/migrate/20130202222224_create_venues.rb:5: syntax error, unexpected '\n' 

     t.string, :venueName

मैं क्या गलत कर रहा हूं, या मैं इसे कैसे ठीक कर सकता हूं?

Answer 1

rails generate scaffold Venue venueid:string venueName:string venueAddress:string venueCity:string venueState:string venueZip:integer venuePhone:string venueAge:int 

बजाय

की कोशिश करो। आपके पास प्रत्येक क्षेत्र के बीच कॉमा नहीं होना चाहिए।

अल्पविराम के साथ

, आप इसे में इस के साथ एक प्रवास जेनरेट कर रहे हैं:

create_table :venues do |t| 
    t.string, :venueid 
    t.string, :venueName 
    t.string, :venueAddress 
    t.string, :venueCity 
    t.string, :venueState 
    t.integer, :venueZip 
    t.string, :venuePhone 
    t.int :venueAge 

    t.timestamps 
end 

आप देख सकते हैं, प्रत्येक t.string/पूर्णांक/आदि। किसी भी तर्क दिए जाने से पहले विधि कॉल में अल्पविराम होता है, जो अमान्य है। यदि यह कार्य करें:

puts, "hi" 

मैं त्रुटि

syntax error, unexpected '\n', expecting tCOLON2 or '[' or '.' 

जो त्रुटि आप था के समान है मिलता है।
