Understanding Action Views in Ruby-on-Rails - Rails in the Real World
(Page 4 of 4 )
Let's take the simple application that was created in the last part a little further. To jog your memory here is the code for the Controller:
class SayController < ApplicationController
defhello
@time=Time.now
end
end
and for the View:
<html>
<head>
<title>Hello, Rails!</title>
</head>
<body>
<h1>Hello from Rails! The time now is<%=@time%></h1>
</body>
</html>
Now let's add a string and float variable to the controller.
class SayController < ApplicationController
def hello
@time=Time.now
@rule=”All sentence should have a starting, a
mid section and an end except”
@price=1000.123
end
end
In the View let's use the formatting helpers (the view is already a template):
<html>
<head>
<title>Hello, Rails!</title>
</head>
<body>
<br>The time now is<%=@time%>
<br>The time now in words<%= distance_of_time_in_words(@time, Time.local(2005, 12, 25)) %>
<br>The highlight works like this<%= highlight(@rule, "sentence") %>
<br>The price 1000.123 in Canadian dollar is
<%= number_to_currency(@price, :unit => "CAN$", :precision => 2) %>
</body>
</html>
That’s all for this part. In the next part the last piece of the puzzle, i.e. the Model component, will be discussed. Once that is completed, I will start to discuss all the components in relation to each other using a project. Till then…
