Adding my controller in an extension

Ruby Apps Radiant CMS
1

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

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 :wink:

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 I get
an error. Here’s what I get in the log file:

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)
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

This is a problem that continues to come up. In the latest extension
generator, as found in mental today, you will see that there is a
line at the top of the generated extension:

Uncomment this if you reference any of your controllers in activate

require_dependency ‘application’

So, that could help.

NameError (undefined local variable or method `behavior_id’ for
#Page:0xb7642820):

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.

Quoting Raphael B. [email protected]:

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?

Hi,
I found adding “no_login_required” to my controller helped-

class ExampleController < ApplicationController

no_login_required

…

That’s working!

thanks Todd!

PS: Did I miss a documentation resource where this is indicated?

require_dependency ‘application’

So, that could help.

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”

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
