Re: [Radiant] What does Admin::ResourceController do?

[Christian Aust]

Hi banane,

my code is packaged as an extension, however I stepped through the code of 
radiant to see how things worked there. Eventually, I followed this tutorial:

http://wiki.github.com/radiant/radiant/creating-a-link-roll-extension
http://wiki.github.com/radiant/radiant/removing-the-scaffold-from-the-link-roll-extension

I created a new database entity that doesn't depend on radiants Page class, but 
is similar to it in some regards. There's a new UI in the admin section to work 
with that entity, plus a number of radius tags that make it available to 
Radiant pages. Regards,

Christian

Christian,

Admin::ResourceController gives you CRUD methods so you don't have to define 
them yourself. Methods like  :index, :edit, :update, :new, :create, :delete  
are built in.

So on a plugin I am working on I only define the show method (controller for a 
podcast's Shows) to get a single 'Show' in my podcast...

class Admin::ShowsController < Admin::ResourceController
  model_class Show
  
  before_filter :find_model, :only => [ :show ]
  
  def show
respond_to do |format|
  format.html # show.html.erb
  format.xml  { render :xml => @show }
end
  end
  
  private
def find_model
  @show = Show.find(params[:id]) if params[:id]
end
  
end

Regards,

-Bill

replace
"   admin.page.edit.add(:form, "mediamaid_gallery", :before=>
"edit_page_parts")"
with
   admin.page.edit.add(:form, "header", :before=> "edit_page_parts")
(the name of the partial file without the underscore, or .rb)

Re: [Radiant] What does Admin::ResourceController do?

[banane]

Hi Christian

Not sure quite what your objective is, but a couple things I'm
thinking while looking at your code:

- the usual thing to do for extensions is not to edit the gem code,
but make an extension directory (/vendor/extensions/your_extension)
and in that file directory structure, include files that will extend
the Radiant code base. So to add to the Admin UI, as I think you want
to do, you'd add a haml file in
/vendor/extensions/your_extension/app/views/admin/_header.html.haml,
and then in the Ruby file that is your extension
(/vendor/extensions/your_extension/your_extension.rb) you'd include a
line of code that would tell the rendering view for the Radiant admin
to include your partial:

admin.page.edit.add(:form, "mediamaid_gallery", :before=> "edit_page_parts")

This page on the wiki really explains well how to change the Admin UI:
http://wiki.github.com/radiant/radiant/modifying-the-page-ui

Also, getting started on extensions (written by moi) with a focus on
converting ruby apps to Radiant extensions, may explain some of hte
basic architecture.

[Radiant] What does Admin::ResourceController do?

[Christian Aust]

Hi all,

I'm writing an extension to Radiant that defines new database entities. The 
docs suggest to let my controller inherit from Admin::ResourceController, to 
"get a lot of functionality for free". What is that functionality, specifically?

In particular, I've been confused by that :singular and :plural stuff in there, 
what's that? When do I need that?

What's going on with the @template_name and @controller_name variables, what do 
I need them for?

As I've mentioned before, Radiant itself is pretty neat, but documentation on 
these parts of its public API isn't only lacking but non-existant. That makes 
it harder to understand errors like this: My entity is called "City", I've 
copied all relevant code from Radiants Page view and controller. The edit haml 
throws this error:

undefined method `cities' for #

Extracted source (around line #1):

1: - render_region :main do |main|
2:   - main.edit_header do
3: %h1 Edit City
4:   - main.edit_form do

/opt/local/lib/ruby/gems/1.8/gems/radiant-0.8.1/app/helpers/admin/regions_helper.rb:25:in
 `send'
/opt/local/lib/ruby/gems/1.8/gems/radiant-0.8.1/app/helpers/admin/regions_helper.rb:25:in
 `lazy_initialize_region_set'
/opt/local/lib/ruby/gems/1.8/gems/radiant-0.8.1/app/helpers/admin/regions_helper.rb:3:in
 `render_region'
/Users/christian/mueller/vendor/extensions/mueller/app/views/admin/cities/edit.html.haml:1:in
 
`_run_haml_vendor47extensions47mueller47app47views47admin47cities47edit46html46haml'

It feels like I've got something wrong while copying code, but I can't easily 
tell what. Can you? Kind regards,

Christian
