How to make conditional link via active_scaffold?

hi everybody!
Link to question on ruby on rails - How to add conditional link via active_scaffold? - Stack Overflow

As everybody usually says, I’m newbie in Ruby on Rails) and have
following issue:

I have a search form

and I would like to have ability to add new msisdn if it doesnt exist.
So I make fake insert and want to add conditional link to my
active_scaffold grid instead of currently exist ones:

config.action_links.add :submit_create, :label => “Create blacklisted
user”, :type => :record, :confirm => “Are you sure?”, :inline => true,
:method => :get
Here is my controller

class CCare::UserstatusController < ApplicationController

before_filter :filter_search

verify :method => :post,
:only => :stop,
:redirect_to => { :action => :index }

>  active_scaffold :users do |config|
>    config.label = "User Status"
>    config.list.columns = [:msisdn, :user_agent, :network ]
>    config.actions = [:search, :field_search, :list, :nested]
>    config.actions.swap :search, :field_search
>    config.field_search.columns = [:msisdn]
>    config.columns[:id].label = "ID"
>    config.columns[:id].search_sql = "users.id = ?"
>    config.columns[:id].search_ui = :text
>
>    config.columns[:msisdn].search_sql = "users.msisdn = ?"
>    config.columns[:msisdn].search_ui = :text
>
>    config.columns[:network].sort = {:sql => "network.network" }
>    config.columns[:network].search_sql = "network.network"
>    config.columns[:network].search_ui = :select
>    config.columns[:network].actions_for_association_links =

[:show]
> config.columns[:user_agent].label = “Device”
> config.nested.add_link(“Subscriptions”, [:user_service_list])
> config.nested.add_link(“Contact History”, [:user_contact])
> config.action_links.add “show_stop_all”, :label => “Stop
All”, :type > => :record, :crud_type => :create, :inline => true,
:position => :after
> config.list.always_show_search = true
> end

params[:search][:id].empty? >and not params[:search][:id] =~ /^[0-9]+$/

I tried to put method is_msisdn_exist into

active_scaffold :users do |config|

end
but it returned error: method not found. How can I implement my
conditional link?

Did you try

render :super
