#active admin

This will work with pre 1.0.0 versions where active_admin used metasearch gem for filters. Below is how you can add a custom field as filter and use it to generate search results using a custom search function:

For me active_admin did break down when we added a polymorphic association to an existing model, and the filter on association stopped working. We suddenly started seeing “no implicit conversion of nil into String“ exceptions. I then had to figure out how to write a custom filter for active admin - and believe me it was like walking in the Sahara Desert =P , with little/no documentation around.

Do let me know in case this helped you and I saved you from getting lost in the great Sahara ;)

TerranetAdmin – Administration Framework for Laravel (Project Management Tools)

Purchase $19.00 TerranetAdmin is a Laravel based framework for creating administration interfaces. It abstracts common business application patterns to make it simple for developers to implement beautiful and elegant backend interfaces with very little effort. TerranetAdmin has been inspired by well known Ruby On Rails administration package called ActiveAdmin. A number of very useful artisan…

In my rails project, application.rb has the following line by default:

config.active_record.whitelist_attributes = true

This means that all attributes are protected from mass-assignment unless opened up in the model by doing something like:

attr_accessible :xyz, :abc

Now active admin does mass assgignments all over the place when updating stuff from its admin portal.

So i guess we can:

add all attributes to attr_accessible, which would be stupid or

we can update each model under the admin directory and list out the things its going to show, update etc.

The 2nd solution somewhat works but the whole point of using active admin is so i can open up the whole thing for my co-founder and he can go nuts, tweaking things. Writing every models accessible fields will drive me nuts which is not cool.

So this is what i ended up doing:

First, to each model under app/models I added the following line:

attr_accessible *column_names, :as => :admin

Then In the active admins initializer file active_admin.rb i added the following:

module ActiveAdmin class BaseController with_role :admin end end

Thats it! Now all columns are accessible as long as the role making the udpate is admin and I have instrcuted active admin's base controller to make all updates using role admin
