Hi all,
I have two classes: a player class and a game class. Each game has two
player IDs. I would like the game show view to be able to display each
player's full name via a method, as follows:
<%=h Player.get_player_name(@game.player2) %>
Here is the method definition in my players controller:
def get_player_name(playerID)
@player = Player.find(playerID)
@playerName = @player.firstName + " " + @player.lastName
end
When I try to view the page, I get the error:
Showing app/views/games/show.html.erb where line #8 raised:
undefined method `get_player_name' for #<Class:0x252de68>
Extracted source (around line #8):
5:
6: <p>
7: <b>Player2:</b>
8: <%=h Player.get_player_name(@game.player2) %>
9: </p>
10:
11: <p>
I can call the get_player_name method from a player view. Clearly I
don't understand something about how rails does its scoping, but I am
not sure where to look. For instance, I don't see anything in my
Learning Rails book that might explain how this works.
My question is: where can I put my get_player_name method so that it
can be accessed by other classes as well?
I am actually surprised that I can't access the method, because the
following does work from within my game show view:
<%=h Player.find(@game.player1).firstName + " " +
Player.find(@game.player1).lastName %>
Thanks,
Stu
