Variable Issue

Hi, I have an issue with a variable creating an array...
First, I initialize the array.

@data = []

Code (markup):

Then I add the data.

@data << [...]

Code (markup):

Then I display the results

<% @data.each do |data| %>

Code (markup):

It works great... but if I change the variable name to @x it fails and display an empty array...
I dont understand why.
Any help please?

 

There is something weird here... kind of cache or something...

I change all variables to @x but in html I leave @data.each do |data| and it keeps sending me the same results...

 

Done.
I had to restart the server..
The weird thing is that Im in development environment...

 

robzdc, this is not an error thats how variables are meant to function in Ruby.

@variable stands for instance variable, by using that variable the data can be used in any function with in the class.

When you did @data, u created such a variable and this variable can be accessed in the view.

When you use "variable" a local variable is made it has validity only within that function you can't use that variable in the view.

 

The error was because I'm using the function in lib/ directory, so I have to restart the server to reload the data.

 

Ah I c, well the reason why you had to restart, to make use of those values was because Rails would load (Loading to memory) the contents of lib/ only during its initial start.

Thanks for posting the question, learned something new today..
