Question: How do I change the order of fields in my form or show page?

Markdown Asks kevinpfromnm

does hobo understand how to display a has_many through relationship?

I’m trying to add a association of many lots per user.

class Lot < ActiveRecord::Base

  hobo_model # Don't put anything above this

  fields do
    number :integer
    code   :string
    timestamps
  end
  has_many :lots_users
  has_many :users, :through =>'lots_users', :foreign_key =>'user_id'
.....

class User < ActiveRecord::Base

  hobo_user_model # Don't put anything above this

  fields do
    name          :string, :required, :unique
    email_address :email_address, :login => true
    administrator :boolean, :default => false
    timestamps
  end
  has_many :lots_users
  has_many :lots, :through =>'lots_users', :foreign_key => 'lot_id'

....

class LotsUsers < ActiveRecord::Base
  belongs_to      :user
  belongs_to      :lot
end

    yes it does understand. i think you need to update your viewhints files…

    in user_hints.rb put…

    children :lots

    and in lot_hints.rb put

    children :users

    and possibly

    has_many :users, :through =>'lots_users', :foreign_key =>'user_id', :accessible => true

    or

    has_many :lot_users, :accessible => true

    viewhints children will work for the show pages. To be able to modify associated models through the new and edit forms, you need to tell the model that the association itself is accessible from the model that should be able to create/edit the association. Once you do that, the forms will update with a default multi-model form that should be good for common use cases.

    Depending on which association is accessible will change the behavior of the form. If the join model (in this case, the lot_users), you will be able to create links to the existing lots, or users depending on which model you’re accessing from, but not new users or lots. If you put the accessible on the has_many ...,:through => ... association, you’ll be able to create new records from the user (or lot) new and edit forms.
