django subquery via orm -


मेरे पास मॉडल हैं: 

  वर्ग साइट (models.Model): profile = models

मैं इस क्वेरी के बराबर डीजेंगो orm के माध्यम से कैसे कर सकता हूं? 

  SELECT * साइट से जहां 2 नहीं है (साइट_आईड प्रोफ़ाइल_ब्लैक सूची से WHERE profile_site.profile_id = site.profile_id)

मुझे कुछ प्रकार की ब्लैकलिस्ट फिल्टर की आवश्यकता है I प्रत्येक साइट में उपयोगकर्ता (प्रोफ़ाइल) है। इस उपयोगकर्ता की साइटों की काली सूची है मैं एक्सपैमल के लिए आईडी = 2 के साथ साइट की खोज करता हूं और मुझे साइटों की जरूरत है चुड़ैल के मालिकों की कोई सूची नहीं है। 2/2 एसक्यूएल। आप जो परिणाम चाहते हैं, उसके संदर्भ में सोचें।

मुझे सच में समझ में नहीं आ रहा है कि आप उस एसक्यूएल में एक subquery का प्रयोग क्यों कर रहे हैं। ऐसा लगता है कि आप जो करना चाहते हैं वह सभी साइटें मिलती हैं जिनके पास एक श्रेणी है जिसका आईडी 2 है। क्या यह सही है?

यदि हां, तो आप क्या चाहते हैं: 

  Site.objects.filter (category__id = 2)

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
