Difference in SQL syntax for enabling a constraint (SQL Server) -

-

क्या इन दो विधियों में कोई अंतर है? 

  वैकल्पिक तालिका [table_name] चेक चेक चेक कन्स्ट्रेंट के साथ [constraint_name]

और 

  वैकल्पिक तालिका [table_name]

से:

जांच के साथ | NOCHECK के साथ:

यह निर्दिष्ट करता है कि तालिका में मौजूद डेटा नए या जोड़े गए या फिर से सक्षम विदेशी कुंजी या चेक बाधा के विरुद्ध मान्य नहीं है या नहीं। यदि निर्दिष्ट नहीं किया गया है, तो चेक के साथ माना जाता है।

इसलिए, चूंकि यह डिफ़ॉल्ट "इसे चेक" करना है, इसमें कोई अंतर नहीं है।

python - Django Custom Admin Block For center of admin -

-
So I'm overriding change_form.html to add some features to my admin page. Everything is working fine, I am currently using the "after_field_sets" block, but I want to put content between this field in my field_sets, not after that. I set the field above and below the new set, but I can not understand which block is used to put them in the middle of field sets. There is a list of all blocks text "> After reading the code referenced by the link you posted I reached the conclusion that the block you are looking for does not exist in it called content There is a block but more than just that "main content" but this is not the end of the world, you still have to make the template IR order to "make some space" for your content.
