Attributes_table formatting using Arbre in ActiveAdmin

I am displaying an ActiveAdmin registered model to the user.

ActiveAdmin.register ConfigurationFile do
  show do
    attributes_table do
      row :name
      row :filename
      row :content
    end
  end
end

:content is a string with newlines, but when rendered by Arbre newlines and extra whitespace are dropped.

How can I display :content without dropping extra whitespace and newlines?

How can I have a div with multiple children in ActiveAdmin/Arbre

I have this code:

div class: item.ui_type do
  link_to image_tag(item.image.image_public_url), item.target)
  link_to item.label, item.target
end

Basically, I want a div with 2 links inside. However, only the last element is getting rendered, presumably because what gets rendered inside the body is the return value of the block.

I know I can declare those as an array and join them, but then I need to call html_safe. I'm trying to find a way to do this when you actually don't trust the input that you're receiving.

This seems like it should be an extremely simple thing to do, but I can't find it anywhere.

Any pointers?

Activeadmin: Could not find arbre-1.0.1 in any of the sources

I'm trying to run rails g active_admin:install script after installing of activeadmin gem. When I run this script I get an error

Could not find arbre-1.0.1 in any of the sources
Run `bundle install` to install missing gems.

Although I've already installed all necessary gems and my app is using arbre gem:

Using arbre 1.0.1

Gemfile:

source 'https://rubygems.org'

gem 'rails', '4.1.1'
gem 'sqlite3'
gem 'sass-rails', '~> 4.0.3'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0'

gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 2.0'
gem 'sdoc', '~> 0.4.0', group: :doc
gem 'spring', group: :development

gem 'devise'
gem 'activeadmin', github: 'gregbell/active_admin'

How can I fix that problem? Thanks!

Row level caching with "Index as Table"

I am displaying a table with ActiveAdmin using the "Index as Table" functionality:

index :pagination_total => false do

    if Ability.new(current_user).can? :manage, :metric
        selectable_column
    end

    column '' do |metric|
        links = link_to(metric.icon, admin_metric_path(metric), :title => metric.comment)
        links += link_to(metric.data_icon, admin_metric_path(metric)) unless metric.datum_ids.empty?
        links
    end

    column 'Status', :success, sortable: :success do |metric|
        metric.success == 1 ? status_tag('Success', :ok) : status_tag('FAILED', :error)
    end
    column 'When (UTC)', :createddttm
    column 'What', :metric_name
    column 'Area',    :logarea
    column 'Subarea', :subarea
    column 'Value',   :value
    column 'Machine', :machine_name, sortable: 'machinename.machinename'
    column 'Domain',  :domain_name, sortable: 'domain.domainname'
    column 'Product', :product_name, sortable: 'product.productname'
    column 'Version', :product_version, sortable: 'product.productversion'
    column 'Install Type', :install_type, sortable: 'product.productinstalltype'
    column 'Lang', :language
    column 'Duration', :duration
end

Given that the row data does not change, I would like to add row level caching of the rendered html with a long expiry time but I can't figure out how to hook into the row rendering code in Arbre.

I am currently caching the entire page for 60 seconds but that is not optimal. My cache store is Dalli / memcached.

How to DRY up arbre code into a reusable component?

I have a common pattern or repeated code that I'd like to DRY up in my ActiveAdmin views. I'm using arbre components to render as much of my views as I can and I'd like to keep it that way if possible (i.e. I don't really want to convert to straight up HTML in the normal fashion -- I'm trying to understand the arbre way here). Here's the code I'd like to DRY up:

clients.in_groups_of(3).each do |clients_group|
  columns do
    clients_group.compact.each do |client|
      column do
        panel client.name do
          # ...
        end
      end
    end
  end
end

After reading through the documentation in the arbre gem, I started to try to create my own, custom arbre component. But I was quickly forced to realize that I have no idea how to satisfy arbre. I couldn't figure out how to pass my local variables into the block. For example:

# config/initializers/active_admin.rb

module ActiveAdmin
  module Views
    class ClientsBreakdown < ActiveAdmin::Component
      builder_method :clients_breakdown

      def build(clients, attributes = {})
        group_size = attributes.delete(:in_groups_of) { 3 }

        clients.in_groups_of(group_size).each do |clients_group|
          columns do
            clients_group.compact.each do |client|
              column do
                panel client.name do
                  super(attributes) # Doesn't seem to matter where this `super` call
                                    # is, but I do want to be able to pass `client`
                                    # into the `clients_breakdown` block here
                  # yield(client)   # -- I've also tried adding this.
                end
              end
            end
          end
        end
      end
    end
  end
end

Then, calling this in my ActiveAdmin User view might look like:

clients_breakdown(Client.all, in_groups_of: 2) do |client|
  ul do
    li client.name
  end
end

Running the above code results in this error:

UPDATE 2 The exception has changed to this after moving my custom component code into the ActiveAdmin::Views module.

My key issue seems to be that I can't just call yield(client) where I currently have super(attributes). But that's an arbre thing so I don't know what to do there to pass the client into the calling block. Is this the right track or is there another way to DRY this up?

UPDATE 1

I've realized that the call to super can happen anywhere in the build method and really has nothing to do with what is output. So even if I move the super(attributes) call up... I still can't figure out what to put inside of the panel block so that I can render the rest of my arbre components in there from the call to clients_breakdown.

Active Admin : Can't access show/edit pages

I'm having an issue with Active Admin. Here are the versions :

• ruby '2.2.1'

• rails '4.2.0'

• activeadmin : 1.0.0.pre1

• arbre : 1.0.3 (mentioning this one because it seems to be linked to my issue somehow)

We upgraded to rails 4.2 and had to upgrade activeadmin as well (from 0.5). After a couple of tweaks (especially the authorization system) everything seems to be fine, except for 1 big issue : I can only access the index pages. When going to a page with an ID (for example : "http://localhost:3000/admin/companies/2968"), I am getting this error :

No route matches {:action=>"edit", :controller=>"admin/companies", :format=>nil, :id=> #{User id: nil, [all user attributes with nil value]}}. Missing required keys: [:id]

Looks like the param[:id] got changed to an empty user somehow, which of course makes it break.

Here's what I know :

• when putting a binding.pry on top of my ApplicationController and inspecting the params, I get {:action=>"edit", :controller=>"admin/companies", :format=>nil, :id=>2968} (so no problem here)

• the lines that raise the error are :

active_admin/resource/show.html.arb

-> arbre/element/builder_method.rb#insert_tag

-> arbre/element/builder_method.rb#build_tag

-> actionpack/actiondispatch/journey/formatter#generate (when this method is called, the path_parameters ID value is already corrupted, which raises the error)

Any idea why my ID parameter is not interpreted correctly / where I could look further ?

EDIT >> I have this in my routes.rb

ActiveAdmin.routes(self)
devise_for :admin_users, ActiveAdmin::Devise.config

And the generated routes look fine with rake routes (in this particular example, I have admin/companies#edit admin_company GET /admin/companies/:id(.:format)

EDIT2 >> In case it wasn't clear, this happens for all show pages. If I go to http://localhost:3000/admin/projects/ for example, it works fine, but http://localhost:3000/admin/projects/23815 gives me id = empty user as well

Active Admin Rails 4 inline form

I am using on Rails 4 ActiveAdmin and Money-Rails. Is there a way to have two or more inputs in a single line of text?

para "Please enter the amount"
f.input :amount_due_currency, :label => "Dollars ",:input_html => {:style => 'width:3%'}
para "and"
f.input :amount_due_cents, :label => "cents ", :input_html => {:style => 'width:10%'}
para "to deposit on your account."

the output that I need would look like Please enter the amount __ Dollars and __ cents to deposit on your account.

I tried string interpolation but that fails. Can someone help me please?

How to use Arbre gem in rails?

I want to try the Arbre gem for rails. There is an example on this page: https://github.com/activeadmin/arbre/blob/master/README.md

Where must I paste the next code?

html = Arbre::Context.new do
  h2 "Why is Arbre awesome?"

  ul do
    li "The DOM is implemented in ruby"
    li "You can create object oriented views"
    li "Templates suck"
  end
end

I want to try the code above, but I don't know where I must paste it. Which file? Which method? I pasted the code into my controller, but it doesn't work.

How to use Rails' simple_format with special characters?

On Rails 3.2.13, simple_format does not return what I expect it to do, on an admittedly convoluted case:

> simple_format("a <= 2, b < 4")
"<p>a &lt; 4</p>"

Since this case does not seem to work properly (I'm losing half my string!), is there a way to pre-escape special characters so that it works everywhere?
