sql - rails active record nuances and protecting against injection attacks -

-

When I do a query ...

Any help between using help Whether there is a significant difference or

booking.find_all_by_user_id (1,: joins = & gt;)

;; Confirmation) booking.fund (: all ,: joins = & gt;: confirmation, conditions => ['bookings.user_id =?', 1])

No, about the injection attacks, the find_by method should be safe, however, the sole killer's fault, the user code is directly related to his / her Terms while using the inside of the Ultimate, such as using the search method, such as: 

  book.find (: all :: joins = & gt ;: confirmation, terms => ['bookings.user_id = # {params [user_id]]}'])   
 Exactly this is the way you have done and will filter things out with the  Find  method. 
 
  Booking.find (: all ,: joins = & gt ;: confirmation, terms => ['booking.user_id =?', Parameters [user_id]])

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. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

-
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
