javascript - Rails redirect_to after jquery $.post -

-

Why can not my browser go to a new page when I submit it?

I think there is a button that posts and functions data in my controller.

My coffee script: 

  $ Post "/ token / create", Json   
  create tokens controller #   
  redirect_to root_path, notice: 'parser successfully created I went.'   
  log file  looks like this works:  
  to get started / "create / token / 2014" Make 127.0.0.1 -10-08 10:27:39 -0400 as processing by * TokenController # * ... as found in http: // localhost: 3000 / full 302 in 372 (active record: 10.0ms) "/" For 127.0.0.1 2014-10-08 10:27:40 -0400 by Visitors Controller as processing # index * / * ... In 2009 complete OK 2891ms (view: 2886.6ms | ActiveRecord: 3.0ms)   
 but the page I'm on can not change Is obtained. On which page do I specify the page in the "redirect_to" row, how do I create it?   
 
 
 You can do the following:  
  def = # Do some things if request.xhr? # If the test is an AJAX call render JS: "document.location = '# {root_path}'" else redirect_to root_path, notice: 'the parser was created successfully.' End   
 Do you want to use  flash  in AJAX cases too? Check this answer: (and well, give your answer if it helps you)

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
