undefined local variable or method `id' for

8.)
Is this RESTful?
I have a site
http://somelist.comthat stores peoples names in a list.
I made the following routes
GET '/name/new' # for showing a new form
GET '/name/create' # for submiting a 'new' name form,
# and creating
GET '/name/:id/delete' # for submitting a deleting for a name
GET '/name/:id/edit # for showing a new edit form
GET '/name/:id/edit/post' # for submitting an edit
# from a form
Please give a little explanation.
No, because your using GET for everything which is not very representational. GET '/name/create' should use POST GET '/name/:id/delete' should use DELETE GET '/name/:id/edit/post should use PUT
9.)
What do you think of my controller? I don't even need a view. Why shouldn't I put all this in my controller?
get "/" do
pageTitle = "myApp!"
"<!DOCTYPE html>
<html>
<head>
<title>#{pagetitle}</title>
</head>
<body>
<div>
Hello there!
</div>
</body>
</html>"
end
You have html in your .rb file? Even if this compiles, you should still use a .erb for your views to separate functionality.
10.)
Look at my view! This works, but why shouldn't I be doing things this way?
app.rb
get '/person/:name` do
erb :show
end
show.erb
<div>
<% person = params[:name] %>
Hello <%= person %>
</div>
it's better to create person in your .rb file like this: get '/person/:name` do @person = params[:name] erb :show end
The ruby in your .erb should be purely for formating the data in order to present it. The more you can put in the .rb the better because it will reduce the load on the browser.
