Hi,

I’m looking to add code to handle a form’s action. I wanted to add  
extension with a controller, but got stuck into problems. What are the  
steps involved in doing what I want? Is this correct:

- generate my extension
- edit the extension’s class (child of Radiant::Extension) to add a  
route to my controller. Question: is the controller visible or should  
I require a certain file, or alter the paths searched for requires?
- write my tests and controller code

Thanks in advance

Raph

Sounds like you’re going down the right path. What problems were you  
running into?

I’m working on a simple mailer extension (I know the mailer extension,  
it doesn’t do whatn I need 😉

When working with the latest 0.6 gems, the controller is not found. I  
had to add this to simple\_mailer\_extension.rb:

require File.dirname( **FILE** ) + ‘/app/controllers/simple\_mailer’

but then I got

/usr/lib/ruby/gems/1.8/gems/radiant-0.6.0/vendor/rails/activesupport/lib/active\_support/dependencies.rb:266:in  
`load\_missing\_constant’: uninitialized constant ApplicationController  
(NameError)

I then went another way and checked out radiant from the svn  
repository. In the simple\_mailer\_extension.rb file, I add this:

define\_routes do |map|  
map.connect ‘/simple\_mailer/:action’, :controller =\>  
‘simple\_mailer’  
end

And I have a simple\_mailer controller:  
$ cat  
vendor/extensions/simple\_mailer/app/controllers/simple\_mailer\_controller.rb  
class SimpleMailerController \< ApplicationController  
def index  
end  
end

When I try to access [http://localhost:3000/simple\_mailer/index](http://localhost:3000/simple_mailer/index) I get  
an error. Here’s what I get in the log file:

Processing SiteController#show\_page (for 127.0.0.1 at 2007-04-03

Rendering  
./script/…/config/…/vendor/rails/actionpack/lib/action\_controller/templates/rescues/layout.rhtml  
(500 Internal Error)

It seems the request is not routed correctly. I took a look at the  
ldap extension  
([http://dev.radiantcms.org/radiant/browser/branches/mental/extensions/ldap](http://dev.radiantcms.org/radiant/browser/branches/mental/extensions/ldap))  
but didn’t find any indication of what I’m doing wrong. I guess it  
could be a really simple thing I forgot to do…

Thanks in advance for your help

So, that could help.

Now this is interesting. You can see in migration 010 that  
behavior\_id’s should not be an aspect of Radiant in 0.6.0.

Hi,  
I found adding “no\_login\_required” to my controller helped-

class ExampleController \< ApplicationController

no\_login\_required

It helps indeed, but I didn’t have this comment in the generated  
extension. This is with the 0.6rc2 and the svn checkout I did some  
days ago:

$ ./script/generate extension test  
…  
$ cat vendor/extensions/test/test\_extension.rb  
class TestExtension \< Radiant::Extension  
version “1.0”  
description “Describe your extension here”  
url “[Fastest Web Hosting Services | Buy High Quality Hosting](http://yourwebsite.com/test)”

# define\_routes do |map|

# map.connect ‘admin/test/:action’, :controller =\> ‘admin/test’

# end

def activate  
# admin.tabs.add “Test”, “/admin/test”, :after =\> “Layouts”,  
:visibility =\> [:all]  
end

def deactivate  
# admin.tabs.remove “Test”  
end

end

When require the application dependency, the route is followed, but it  
requires me to log into radiant. Can I also develop an extension that  
is available without the need to log into radiant? I simply want to  
add a controller that doesn’t need an admin part. What if eg I want to  
let people leave their email to I can contact them later on? I though  
I’d do that with a controller to which the form is submitted, but then  
this controller has to be available without logging into radiant. Or  
shold I go in the direction of a plugin/engine?

Thanks for your help
