node.js - Iterate Mongoose Properties in Jade -

-

I am trying to produce a list of properties from a Mongoose object, but I also get very Javascript Helper functions I'm thinking that there is a clear way to output only my mouth schema properties.

My Z display code looks like this: 

  h4 legacy data ul - every val key, D.old li = key + ":" + val   
 and my strange schema definition  
  entry = new schema ({old: {depositor: string, table: string, verged: number}});   
 But when the page is provided, a bunch of other JavaScript properties and functions are output at the same time. E.g.  
  _scope: [object] toObject: function () {return.get (path); } Wordid: 2035 ...   
 Is there an easy way to repeat through my schema through properties? I can use a specific list, but I was thinking that there is a good way.  
 Actually, how would I write in the specified way? In Ruby I know that I can do  ['wordid', 'submitter'].  But what's the equivalent in Z?   
 
 
 You are facing prototype properties of the object. You can filter them with  .hasOwnProperty   
  - each value, key in d.od - if (d.old.hasOwnProperty (key)) = Key + ":" + Val

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...
