ransack

I'm trying to export a list of Ransack ( Railscast ) results to a CSV file ( Railcast ). However, it keeps exporting all of the objects, instead of the results returned by the Ransack search. Can anyone tell me where I'm going wrong? In the Reports controller, I've tried passing both @bookings and @search.result: def index @search = current_user.bookings.search(params[:q]) @bookings = @search.result @search.build_condition respond_to do |format| format.html format.csv { render text: Booking.to_csv(@bookings) }\ end end And then the Booking to_csv method: def self.to_csv list CSV.generate do

Say for example I have an event with start_date and length (as integer representing days). In the model I define end_date as start_date + length.days very simply as you would expect: def end_date start_date + length.days end All works fine in the template, I can use event.end_date to display the start date plus however many days length was set to, however , I want to now order the events by the end date using Ransack. The sort link for start_date looks like this: <%= sort_link @q, :start_date, "Start" %> If I try the same for end_date ( <%= sort_link @q, :end_date, "End" %> ) it unfortunately

I'm using rails ransack ( https://github.com/ernie/ransack ) to allow the users to filter and sort some records. I get the filtered and sorted records using traditional methods. @invoices = Invoice.search(params[:q]).result Now I would like to get some summary information so I have @invoices = Invoice.search(params[:q]).result @summary = @invoices.select("sum(balance) as balance_total").first Except when the user specifies a field to sort. I get the SQL error: Column "project_name" is invalid in the ORDER BY clause because it is not contained in either an aggregate function or the GROUP BY

I have a search form in the header of my app and I would like to use this search form to search through multiple models within the application. For example a request like /search?q=rails should trigger a search through multiple models like Work , Project , User and their defined attributes. I wanted to use Ransack because I already use it on the Work model in a different area of the app. I think I don't quite understand Ransack yet and the documentation always points out that you have to define @q = MyModel.search(params[:q]) to use it in the form search_form_for @q . Is there a way where you

I'm wondering if anyone has experience using Ransack with HABTM relationships. My app has photos which have a habtm relationship with terms (terms are like tags). Here's a simplified explanation of what I'm experiencing: I have two photos: Photo 1 and Photo 2. They have the following terms: Photo 1: A, B, C Photo 2: A, B, D I built a ransack form, and I make checkboxes in the search form for all the terms, like so: - terms.each do |t| = check_box_tag 'q[terms_id_in][]', t.id If I use: q[terms_id_in][] and I check "A, C" my results are Photo 1 and Photo 2. I only want Photo 1, because I asked

I have a HABTM relationship between the Theme and Quote models. The themes index view displays the count of quotes associated with each theme. I'd like to add a Ransack sort_link on that column, so the themes can be sorted by their count of associated quotes . I have done this successfully with has_many associations using a counter cache column, but Rails does not support counter cache columns for HABTM associations. So far, I've got a scope that adds a virtual attribute called quotes_count (by performing a single query, avoiding N+1) to the Theme model: scope :with_quotes_count, -> do joins(
