Hi Raimon,
Take a look at one of my blog posts on using Camping and OAuth, there a
section regarding the use of filters:
http://blog.monnet-usa.com/?p=293#caoatodoa
I had packaged Magnus' filtering_camping library as a gem.
You can also see how I use filters in the Camping OAuth plugin:
http://github.com/techarch/camping-oauth
<http://github.com/techarch/camping-oauth>
See
|To implement filtering:
| 1) |gem install filtering_camping
2) in your main Camping module add:
include CampingFilters
|
3) still in your main module add your global filters:
before :all do | x |
Camping::Models::Base.logger.debug "[before] filter on
#{x.inspect}"
end
after :all do
end
4) add your controller specific filters
# when targeting a single controller
before :MyController1 do
#your filter logic
end
after :MyController1 do
#your filter logic
end
# when targeting multiple controllers use an array
before [:MyController2, MyController3] do
#your filter logic
end
after [:MyController2, MyController3] do
#your filter logic
end
Note you can also use a lambda:
myblock1 = lambda { Camping::Models::Base.logger.debug "hello -
before (Index)" }
before :Index , &myblock1
One of these days I'll write a post on that. ;-)

Hi,
I'm trying to use filters in my Camping App, but at this moment they are not
working ...
I've found some presentation by Jeremy McAnally
(http://slideshow.rubyforge.org/camping.html#1)
At the end, appears a Library that makes our life easier, but I can't find this
library.
Also, this presentation is from 2007 and we are now in 2011, so maybe Camping
can handle those filters in an easy way.
I use them in Rails but here I'm getting always ./list.rb:278: uninitialized
constant List::Filters (NameError)
Basically what I want to do is before each controller, check if there are some
input variables in the post, and proceed if they are OK or send an error page,
well, preferably a an error status in the header.
thanks in advance,
regards,
r.

Here is what says about Kindling:
Kindling
• A new library by me that takes the top 5-10 “Railsisms” and lets you
use them in Camping
• Currently supports…
• Easy before/after filters
• Static file download/upload
• Easy addition of template handlers, with default support for
ERb
