Community program search

[peregrinator]

We want to add basic search and export functionality to the application. We'll start by allowing admin users to search for an community program by name, organization, or school.

We'll use Ransack to power the search and allow users to export the results as a CSV.

CommunityProgramSearch

• create app/searches/application_search.rb
• create app/searches/community_program_search.rb that inherits from ApplicationSearch
• #new takes a set of parameters and creates an internal ransack search @query for them
• #results calls query.results and adds any needed includes, etc (eager loading)
• #csv calls #results.each and returns a CSV

Admin::SearchController

• #index action that only renders the form if no parameters are present, otherwise uses CommunityProgramSearch and passes the results to the view (and renders form)
• #export action that uses the CommunityProgramSearch #as_csv method that returns the results as a CSV.

app/views/admin/search_controller/index.html.erb

• view as outlined in image
  
• "Export as CSV" button sends along the search parameters to search_controller#export
