I was following this <a href="http://railscasts.com/episodes/362-exporting-csv-and-excel" rel="nofollow noreferrer">railscast</a> video but I'm having serious difficulties to export my data to excel (or CSV for this matter). I'm using will_paginate in some data that I show on frontend like this: <pre><code>sql = "select complex..." @data = paginate_by_sql([sql], :per_page => params[:rows], :page => params[:page]) </code></pre> so, as is, I thought this should work: <pre><code>respond_to do |format| format.html format.xls { send_data @data.to_csv(:col_sep => "\t") } end </code></pre> and it actually downloaded a xls file correctly by the content is all messed up, it shows one row per column and something like this as content: <code>#<Product:0x00000004c83328></code> PS -> using rails latest version :: EDIT :: By one row per column I mean one row only on my excel sheet and on this row COLUMN A = <code>#<Product:0x00000004c83328></code> COLUMN B = <code>#<Product:0x00000004c83329></code> COLUMN C = <code>#<Product:0x00000004c8333></code> (30 columns) UPDATE Did a simple exercise for testing and end up with all columns again in one column only: <pre><code>csv_string = CSV.generate(:col_sep => ",") do |csv| csv << ["row", "of", "CSV", "data"] csv << ["another", "row"] end respond_to do |format| format.html format.csv { send_data csv_string, :type => 'text/csv; charset=iso-8859-1; header=present', :disposition => "attachment; filename=records.csv" } end </code></pre> <code>(:col_sep => ",")</code> is optional I suppose. result: <img src="https://i.stack.imgur.com/SjH14.png" alt="excel output">

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
