perfectlynormal / axlsx_rails

Rails plugin to provide renderer and template handler for axlsx gem.

Axlsx-Rails — Axlsx templates for Rails views

##Installation

In your Gemfile:

gem 'axlsx_rails'

##Requirements

• Rails 3.1, but it has only been tested on 3.2.6

##Usage

Axlsx-Rails provides a renderer and a template handler. It adds the :xlsx format and parses .xlsx.axslx templates.

###Controller

You can either use the typical format:

respond_to do |format|
  format.xlsx
end

or call render directly:

render xlsx: "foobar", filename: "the_latest_foobar", disposition: 'inline'

If you merely want to specify a file name, you can do it one of two ways:

format.xlsx {
	response.headers['Content-Disposition'] = 'attachment; filename="my_new_filename.xlsx"'
}

Or:

format.xlsx {
  render xlsx: "action_or_template", disposition: "attachment", filename: "my_new_filename.xlsx"
}

NOTE: Someday it would be nice to merely say something like: render :filename 'blah.xlsx"

###Template

Use the .xlsx.axlsx extension (sorry if your lysdexic!) In the template, use xlsx_package variable, which is set with Axlsx::Package.new:

wb = xlsx_package.workbook
style_shout = wb.styles.add_style sz: 16, b: true, alignment: { horizontal: :center }
wb.add_worksheet(name: "Foobar") do |sheet|
  sheet.add_row ['Bad', 'spellers', 'of', 'the', 'world', '...']
  sheet.add_row ['Untie!']
  sheet.merge_cells("B1:B6")
  sheet["B1"].style = style_shout
end

If you use acts_as_xlsx, configure the active record normally, but specify the package in the template:

User.to_xlsx package: xlsx_package, (other options)

To set the author attribute upon Axlsx::Package.new, insert the following in application.rb:

config.axlsx_author = "Elmer Fudd"

NOTE: We really ought to allow the author to be set in each call

####Partials

Partials work as expected:

wb = xlsx_package.workbook
render :partial => 'cover_sheet', :locals => {:wb => wb}
wb.add_worksheet(name: "Content") do |sheet|
  sheet.add_row ['Content']
end

With the partial simply using the passed variables:

wb.add_worksheet(name: "Cover Sheet") do |sheet|
  sheet.add_row ['Cover', 'Sheet']
end
