Hello,

I am trying to put together a RoR app using the REVE gem for the  
online game EVE.  
My problem is that I am getting the Stringify Keys error.

###### 

CODE

###### 

char\_sheet.erb.html

\<% require ‘reve’ %\>  
\<%= session[:char\_id] %\>  
\<% api = Reve::API.new(session[:eve\_id], session[:eve\_key]) %\>  
\<% sheet = api.character\_sheet(session[:char\_id]) %\>  
  
  
\<% puts “My name is #{sheet.name}, I belong to the #  
{sheet.corporation\_name} corp and I have #{sheet.balance} ISK” %\>  
  
  
\<% puts “My skills are thus:” %\>  
  
  
\<%= for skill in sheet.skills  
puts “typeID #{skill.id} is at level #{skill.level}.”  
end  
%\>

get\_char\_list

\<% require ‘reve’  
api = Reve::API.new(session[:eve\_id], session[:eve\_key]) %\>

Please select the character you wish to see. Current Server Time: \<% api.current\_time %\>
\<% api.characters.each do |character| %\> \<%= button\_to character.name, :action =\> :char\_sheet %\>  
\<% end %\>  

\<%= button\_to "Logout", :action =\> :logout %\>

account\_controller

require ‘reve’  
class AccountController \< ApplicationController

def login  
session[:user\_id] = nil  
if request.post?  
user = User.authenticate(params[:name], params[:password])  
if user  
session[:user\_id] = user.id  
session[:name] = user.name  
session[:eve\_id] = user.eve\_id  
session[:eve\_key] = user.eve\_full\_api\_key  
redirect\_to(:action =\> “get\_char\_list” )  
else  
flash.now[:notice] = “Invalid user/password combination”  
end  
end  
end

def logout  
session[:user\_id] = nil  
session[:name] = nil  
session[:eve\_id] = nil  
session[:eve\_key] = nil  
flash[:notice] = “Logged out”  
redirect\_to(:action =\> “login”)  
end

def index

end

def char\_sheet  
session[:char\_id] = “char\_id” =\> params[:id]

end

File lib/reve.rb, line 693

693: def character\_sheet(opts = { :characterid =\> nil })  
694: args = postfields(opts)  
695: h = compute\_hash(args.merge(:url =\> @@character\_sheet\_url))  
696: return h if h

##########  
END CODE

any help would be appreciated.

I think that is caused by not passing in a hash where one is expected

ok, changing it to \<% sheet = api.character\_sheet(:characterid =\>  
session[:char\_id]) %\>  
gives me (105) Invalid CharacterID so apparantly that is a step in  
the right direction…

Don’t know anything about REVE… but if you check the RDoc it states:

`
  character_sheet(opts = { :characterid => nil })
Gets the CharacterSheet from
EVE Online | The #1 Free Space MMORPG | Play here now! Expects:
```
* characterid ( Fixnum ) - Get the CharacterSheet for this Character

```
`

`which means it’s expecting a Fixnum and not a string…
