json - Issue "Ext.util.JSONP.request" only request remote server on the first time running -

-

मुझे जावास्क्रिप्ट में कुछ कोड है: 

  Ext.util.JSONP.request ({ Url: 'http://mysite.com/data.php', कॉलबैककि: 'कॉलबैक', कॉलबैक: फ़ंक्शन (डेटा) {चेतावनी (डेटाटाइटल);}});   
 और php:  
  & lt;? Php $ कॉलबैक = $ _REQUEST ['कॉलबैक']; $ आउटपुट = सरणी ('शीर्षक' = & gt; 'ऐप्पल'); यदि ($ कॉलबैक) {हेडर ('सामग्री-प्रकार: टेक्स्ट / जावास्क्रिप्ट'); प्रतिध्वनि $ कॉलबैक '('। Json_encode ($ आउटपुट)। ');'; } अन्य {हेडर ('सामग्री-प्रकार: आवेदन / एक्स-जेएसएन'); गूंज json_encode ($ आउटपुट); } // फ़ाइल test.txt को php फ़ाइल की जाँच करने के लिए $ fp = fopen ("test.txt", a) कहा गया है; फ़िलिट ($ एफपी, "मुझे कॉल करें"); fclose ($ एफपी); ? & Gt;   
 फ़ंक्शन जेएस पहली बार चलाता है, test.txt "कॉल मुझे" है लेकिन जब फ़ंक्शन जे एस दूसरी बार चलाता है, test.txt अभी भी "मुझे कॉल" है मुझे लगता है कि test.txt को "कॉल मुझे कॉल करें" होना चाहिए, क्योंकि मैंने php को दो बार कहा है इससे पता चलता है कि "Ext.util.JSONP.request" केवल पहली बार चलने वाले दूरस्थ सर्वर से अनुरोध करता है। अगली बार यह पिछले डेटा लेगा, लेकिन फिर से सर्वर को कॉल नहीं करेगा कोई भी मेरी मदद करता है?   
 
 
 इस 'कैशिंग' को रोकने के लिए एक परम के रूप में समय जोड़ने का प्रयास करें, मेरे लिए काम किया मेरी पिछली परियोजना में  
  Ext.util.JSONP.request ({url: 'http://mysite.com/data.php', कॉलबैककी: 'कॉलबैक', कॉलबैक: फ़ंक्शन (डेटा ) {चेतावनी (डेटाटिटल);} पैरामीटर: {समय: नई तिथि ()। GetTime ();}}};

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
