In the web application development , there are some situations where we need to create dynamic controllers . Let me have a chance to explain this further .. We'll take an example and try to understand this situation.
Eg:- Assume that We want to create controllers for each user who registered in our site.
In normal situations , we know how to create a controller ...(ruby script/generate controller Example)
But the example I have mentioned , controller name should be dynamic.
Assume that we are going to create the controller with in the registration method. There for the code to generate the dynamic controller should look like this
Class ExampleController <>
def registration
@user_id=session['user']['id'].to_s()
@user=User.find(:first ,:conditions => ["id=?",@user_id])
@partner=Partner.new(params[:company_details])
if request.post? and @partner.save
user_name=@partner.user_name
system("ruby script/genarete controller #{user_name} index")
redirect_to :controller =>"comman" , :action => "welcome"
end
After creating the controller , you may want to write some codes in to the index method of that controller.
To do that we have to write those codes in the applicaion helper class.
Eg:
module ApplicationHelper
$array=[]
@url=request.request_uri.to_s.slice(1..20)
$company=Partner.find(:first, :conditions => ["url="+ "'"+@url+"'"])
$company_name=$company.company_name
$partner_id=$company.id
$array[0]=$company.id
$array[1]=$company.company_name
return $array
end
After writing the above code ,we can call the index method any view that we want....
Have a Nice Day......!
