python - Why can't I set my Django Model's USPhoneNumberField to null=True, blank=True? -


मेरा Django मॉडल: 

  localflavor.us.forms से आयात करें USPhoneNumberField क्लास प्रोफाइल (मॉडल .model): सेलफोन = यूएसफोन फ़ोन नंबर (रिक्त = सच = रिक्त, सच =)

जब मैं एक manage.py syncdb करता हूं: 

  सेलफोन = यूएसफोन फ़ोन नंबर (नल = सच, रिक्त = सत्य) प्रकार त्रुटि: __इनित __ () को एक अप्रत्याशित कीवर्ड तर्क 'नल' मिला

अगर यह जीत गया है तो मैं इस क्षेत्र को कैसे वैकल्पिक बना सकता हूं 'क्या मैं इसे नल के रूप में घोषित करूंगा = सच जैसे मैंने कई अन्य क्षेत्रों के लिए किया?

यूएसफोन फ़ोन नंबर एक फ़ॉर्म प्रकार है, कोई मॉडल प्रकार नहीं

उपयोग (आमतौर पर) है: 

  वर्ग प्रोफ़ाइल (मॉडल Model): सेलफ़ोन = मॉडल.कारफिल्ड (max_length = 20, null = true, blank = true))

और forms.py 

  वर्ग ProfileForm (Forms.Form): # और रूपों। मॉडलफ़ॉर्म सेलफोन = forms.USPhoneNu MberField (...)

वर्ग localflavor.us.models.PhoneNumberField (* आर्ग्स, ** kwargs) एक चरखी है जो जांच करता है

यह मान एक वैध यूएसए-स्टाइल फ़ोन नंबर है (प्रारूप XXX-XXX-XXXX में)।

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
