How is design done on larger rails sites?
(replies: 2)
by jtoy on Thu Apr 13 09:40:37 -0500 2006

Hi, I am working on a the largest rails project I have worked on before. It’s large in terms of how many different directions the application can flow, so there will be many different views. How are people using rails to do the workflow on larger projects?
It is getting too tedious in the controller to have code like:
if @result ==1
render :action => ‘page1’
elsif @result ==2
render :action => ‘otherpage’
else
render :action => ‘returnpage’
How are rails developers managing these kinds of flows?
I would appreciate any suggestions.

what level of interaction does rails have when page caching is used?

From reading about how rails works, it seems when you use page caching in a production environment, the rails stack is bypassed because apache/lighty will see the html file and serve that instead of dynamically generating the page. Is rails really totally bypassed? If so, how can the log files still record what pages where hit in the log directory if rails is totally bypassed?

Disable the output of IRB

Sometimes when you are testing functions, you just want to run the code without irb printing out tons of data to the console.
Normally you type in irb:
1+1
and it will print out
=> 2
if you add a ”;0” or ”;nil”
the result will not be printed, only a 0 or nil. This is only useful when a function prints out to much data to the screen such as an array with 1,000,000 items.
so you would do:
my_function;nil

use page caching and still have acccess to flash

If you want to use page caching, but can’t because you will loose the ability to display error and succcess messages, there is a way around this.
You can put your error in javascript so your pages are always cached, only your javascript will change.
You will need to make sure javascript is loaded from the webserver and that the browser isn’t caching your javascript.
In your javascript template have some code like:

<% if flash[:js_notice]  %>


  var js_notice = "<%= flash[:js_notice]  %>"

<% else %>


  var js_notice = null

<% end %>



<% if flash[:js_error]  %>


  var js_error = "<%= flash[:js_error] %>"

<% else %>



function display_flash(){

  if (js_notice){

    var div = document.getElementById("js_notice")

    div.innerHTML =  js_notice

  }

  if (js_error){

    var div = document.getElementById("js_error")

    div.innerHTML = js_error


  }

}

window.onload = display_flash

Then in your layout have this html:
  <div id="js_error"></div>
  <div id="js_notice"></div>

On each new page request, the javascript code will load and check if there are notices or errrors, if there are, then it will place that error on your page in the appropiate div. show
