ruby on rails 3 - How to specify Has_many order -


मैं Has_many रिश्ते में विशिष्ट आदेश कैसे निर्दिष्ट करूं?

<पूर्व> श्रेणी GolfCourse & lt; ActiveRecord :: बेस है_माध्यम: course_nines समाप्ति वर्ग CourseNine & lt; ActiveRecord :: बेस के लिए सम्बद्धता: गोल्फ़-कैरेज़ का अंत

प्रत्येक गोल्फ़ कोर्स में दो CourseNines होंगे और मैं एक निर्दिष्ट / असाइन करना चाहूंगा < कोड> कोर्सन जैसा कि पहले / सामने और दूसरा वाला जैसा कि second / back जैसा होता है।

धन्यवाद!

यह प्रयास करें: 

  कक्षा गोल्फ़ कोर्स & lt; ActiveRecord :: बेस है_मैं: कोर्स_एनंस डीफ फ्रंट_एनइन ऑर्डर ("बनाया गया एसेट")। पहले () # या जो लॉजिक आपको अंत डीईएफ़ back_nine ऑर्डर ("created_at desc") चाहिए। पहले () # या जो लॉजिक आपको अंत एंड एंड

यह उदाहरण मानता है कि हर गोल्फर कोर्स के लिए आपको हमेशा 2 नैन कॉरर्स होंगे। संभावित रूप से ऐसा करने के अन्य तरीके हैं लेकिन आपको कुछ और विवरण देना होगा कि आप क्या करना चाहते हैं

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
