Multistep Form with Activeadmin

Multistep form with ActiveAdmin?

I've been fretting with this issue myself. I found that you can add your own pages using collection actions in your ActiveAdmin file. Say your model is called MyModel, you would add this to your ActiveAdmin my_model.rb file.

# GET /admin/my_model/page1
collection_action :page1, :method => :get do
  render 'admin/page1'
end

# POST /admin/my_model/page1
collection_action :page1, :method => :post do
  # Do your form processing
  redirect_to test_admin_my_model_path
end

# GET /admin/my_model/page2
collection_action :page2, :method => :get do
  render 'admin/page2'
end

You would then need to create a view at /app/views/admin/page1.html.erb and page2.html.erb

How can ActiveAdmin start sorting columns after the first click on columns' header in ascending order?

Unfortunately what you want to do doesn't seem configurable because desc, the default sort, is hard-coded. However, if you would like a monkey patch, you can put code below in config/initializers/active_admin.rb which overrides the default behaviour.

module ActiveAdmin
  module Views
    class TableFor < Arbre::HTML::Table    
      def order_for_sort_key(sort_key)
        current_key, current_order = current_sort
        return 'asc' unless current_key == sort_key
        current_order == 'desc' ? 'asc' : 'desc'
      end
    end
  end
end

RESTful way to deal with multi-step new action in Rails 3

Have a look at this screencast for a multistep form.

http://railscasts.com/episodes/217-multistep-forms

Ryanb is using a nice way with the validations for each step and keeping everything in the create action so no need to have extra routes.

Creating custom nested forms in RailsAdmin

This isn't a good final answer but I was able to get around the problem with the following JS hack in ui.js

  var oldNestedFormEvents = window.nestedFormEvents.insertFields
  window.nestedFormEvents.insertFields = function (content, assoc, link) {
    if ($(link).closest('.no_tabs').length > 0) {
      return $(content).insertBefore(link);
    } else {
      return oldNestedFormEvents(content, assoc, link);
    }
  }

On custom partials where I want to use a nested form, I simply add the 'no_tabs' class to their containing div and reuse the original insertFields method from bbenezech-nested_forms.

Displaying a comment box on customized ActiveAdmin Show page

I got Answer :-P

ActiveAdmin.register Book do
  scope :all, :default => true
  scope :publish

  show do
    attributes_table :name, :description, :owner, :company, :publish, :publisher
    active_admin_comments # Add this line for comment block
  end 
end

Just add "active_admin_comments" at the end of show block.
I found it on source code of demo site

How to locate unpermitted params :id in active admin?

It's not the building :id, it's the address_attributes that should have the :id added.

So in building.rb:

permit_params :name, :construction_year, :floors, :building_type, :energy_label, :owner_id, :manager_id, :project_ids,
    address_attributes: [:id, :street, :number, :postal_code, :city]
