Hello,

I am using Sinatra to write an application that would act on GET, POST,  
PUT and DELETE actions. I have coded the GET part as follows-

```auto
get '/' do
    @CNs = Data.all()
    erb :index
end
```

The index.erb in ./views has all the rendering logic.

Thus, the get block calls the index.erb file. How should POST and PUT  
should be coded ?

```auto
post '/addnew/:id' do |id|
    erb :addnew
end
```

If addnew.erb will POST and action will be ‘/addnew/5’, then it will  
call the post block again, Isn’t ?

I think, I shouldn’t call the erb :addnew. Instead something else  
should be done.

I am sure this is a very basic thing and a lot of people could have gone  
through this step earlier. Any suggestion ?

Thanks in Advance,
