django - Inherited abstract model, can't save foreignKey fields -

-

Django अनुप्रयोग में मुझे ये मॉडल हैं: 

  class DLL (models.Model): अगली = मॉडल। ('स्वयं', संबंधित_नाम = 'पीटीआईटीम', रिक्त = ट्रू, रिक्त = ट्रू) अगला = मॉडल। फ़ेरिनकी ('स्व', संबंधित_नाम = 'अगला इटैम', रिक्त = सत्य, शून्य = सत्य) वर्ग मेटा : सार = सच

वर्ग SomeData (DLL): name = models.TextField ()

समस्या यह है कि जब मैं अगले या पिछले सेट के साथ कुछ डेटा वस्तु सहेजें

उदाहरण: 

  s1 = SomeData (name = 'one') s2 = कुछ डेटा (नाम = 'दो' ) S2.save () s1.next = s2 s1.save () s = SomeData.objects.get (pk = 2) # अब एस = s1 s.next # कोई नहीं

क्षमा करें, यह पूरी तरह से अच्छी तरह से काम करता है। परियोजना के साथ कुछ अजीब समस्या होनी चाहिए। हल।

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
