[Radiant] Customizing the user admin UI at the column level

[Wes Gamble]

 I have reviewed the contents of 
http://wiki.github.com/radiant/radiant/modifying-the-page-ui in depth.


I have extension that modifies the user model to be attached to 
something called a program, and I've made the change in the DB, and 
modified the user model in my extension code like so:


User  class User  ActiveRecord::Base
  belongs_to :program
end

so that the association will be there.

Now, I would like to be able to display and edit program assignments for 
a given user in the admin. UI.


In my extension's activate method, I added the following lines in the 
hopes of customizing the UI:


admin.user.edit.form  'edit_program'
admin.user.index.thead  'program_header'
admin.user.index.tbody  'program_cell'

thinking that the display of the user admin was super dynamic and it 
would just figure out how to display the edit components based on 
attribute type.


But when I try to look at the index view of users, I get:

`program_header' default partial not found! `program_cell' default 
partial not found! as errors in the index display.


and

`edit_program' default partial not found! as an error in the edit display.
**
After looking into it, though, I see the admin/users/edit and 
admin/users/index views under the Radiant core are more or less 
hard-coded at the column level, but the error messages imply that I 
should be able to add a partial somewhere for my custom fields.


Questions:

What is the preferred way to customize at this level?

Do I need to just override the entire edit and index views?

Is there some Javascript-y way to do this that I'm missing?

Many thanks,
Wes

You're on the right lines, though I would normally use this kind of idiom to 
get more control:

admin.users.edit.add :form, edit_program, :after = something
 
and then you need to create the partial, which in this case would be


vendor/extensions/your_extension/app/views/admin/users/_edit_program.html.haml

If you want it to live somewhere else - eg. to share a form component between 
several models - then you can specify the full path to the partial in the usual 
way:

admin.users.edit.add :form, admin/programs/edit_program, :after = 
something

 Do I need to just override the entire edit and index views?

Much better to avoid that: working through the UI you are relatively safe from 
interface changes and able to co-operate with other extensions.

 Is there some Javascript-y way to do this that I'm missing?

Nope.

best,

will

vendor/extensions/your_extension/app/views/admin/users/_edit_program.html.haml


I did this, and created a file in the correct place, and entered the 
following in my activate method:


  admin.users.edit.add :form, edit_program, :after = edit_roles

My partial looks like this:

- form.edit_program do
  %p
= f.label :program_id, t('program'), :class = optional
= f.select :program_id, Program.all.collect {|p| [p.name, p.id]}

and I get the classic

 |wrong number of arguments (0 for 1)|

message when I try to render the form.  This is because, AFAIK, the 
partial hasn't been passed the form variable as a local.


How does the partial get rendered in the context of the existing form?

Thanks,
Wes
