context.instance_variables

[rellik]

First of all, let me say how great this plugin looks! It's a tool I'm
sure I'll use on quite a few projects.

I am trying to get it set up, but am having some problems. I can't
seem to access my instance variables. I get an 'undefined method'
error.

My code:

RequestsController.after(:feature=>:view) do |context, feature, args,
block|
Mole::DbMole.mole_it(context, feature,
context.session[:user], :some_var =>
context.instance_variable.get(@foo))
end

My error:
>>> Mole Error: After-Filterundefined method `instance_variable' for #<RequestsController:0xb7694a94>

Hi,

   Thanks for the kind words...

   The actual method call to get the controller instance variable should be
   context.instance_variable_get and not context.instance_variable.get

Thanks. You might consider updating your blog to reflect that.

In your original post:

MyController.before( :feature => :show ) do |context, feature, args,

block| Mole::DbMole.mole_it( context, feature,

context.session[:user_id],
:some_var => context.instance_variable.get(@myVar))

Doh !! Sorry, I will update it...

Thanks

I changed the call to instance_variable_get() but am getting the
following error:
>>> Mole Error: After-Filternil is not a symbol

My code is:

### Code ###

RequestsController.after(:feature=>:view) do |context, feature,
args, block|
Mole::DbMole.mole_it( context, feature,

context.session[:user], :my_foo=>context.instance_variable_get(@foo))
end
### End ###

@foo is definitely set in the view() method, as it is used in the
displayed view.

Hum... I suspect something went wrong while persisting the mole info...
I have added some extra debug info to the mole, but in the mean time
try to stick the following line in the mole/module.rb

I am sure our line# won't match but you should see a rescue block that will
look something like:

rescue => ca_boom
  klass.mole_log ">> Mole Error: After-Filter " + ca_boom
end

Add this line to the rescue block

ca_boom.backtrace.each { |l| klass.mole_log l }

And send us the exception trace...

Ah -- The actual call should be instance_variable_get( "@foo" ) and not
instance_variable_get( @foo )

That makes a lot of sense... although it does seem odd that you pass
it "@foo" instead of "foo".. seems repetitive, since the method
itself is called instance_variable_get.

Thanks.. this will greatly change the informativeness of the mole
reports :)

As before, you might consider updating the blog example to reflect
this correct usage

[Fernand Galiana]

Rats... Forgot about that. Thanks for the reminder Patrick !!
