Django Object Filter (last 1000) -

-

How will be known about retrieving previous 1,000 values ​​from a database by Objects.filter? What I am currently doing is bringing me 1,000 values ​​before entering the database (i.e. 10,000 lines and this is bringing me 1-1000 instead of 9000-1000).

Current code: < 

  Border = 1000 store. Afs. (Id = some other [id]) [: border]

Cheers

solution: 

  queryset = shop.objects.filter (id = someArray [id]) border = 1000 count = queryset.count () endoflist = queryset.order_by ('timestamp ') [Count-Limit:]

Endowlist is the query that you want.

Efficiency:

The following queries are from the Dedango docs about the method.

To query a "last" five items, you can: 

  my_queryset.reverse () [: 5] < / Code>

Note that this is not exactly the same as the slicing action. End of the sequence in Python The above example will first return to the last item, then the suburban object and so on. If we had a Python sequence and saw that seq [-5:], then we would see the fifth-final item first. Django does not support that mode of access (truncation from the end), because it is not possible to do it efficiently in SQL.

So I am not sure whether my answer is only disabled, or too highly disabled, I was taken to the order_by for the last question, but I am not sure It makes a difference.

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
