Add User / Equipment Export

[orenyk]

Requested by one of our clients, it would be nice if users could export a CSV of their equipment (essentially a "backup" that could be used to restore the equipment and users via the import function). Let's see if we can swing this into v5.5.0.

going to handle this similarly to how we handle importing csvs, but with an export button on the equipment and users index pages instead of a full export view

[esoterik]

trying to figure out the best way to export equipment data, because that essentially means three CSV files--rubyzip might be a good option?

[esoterik]

also, a test that I wrote for this is currently failing, and I'm not really sure why (this one)

We could just have a separate export button for each of the resources - categories, equipment models, and equipment items. This is kinda tied into #899 as well, it would be great if this feature was written in a modular way for each controller so that it's as DRY as possible.

I'll look into the test later when I'm in Linux and can test it out.

Ok, after looking into this I'm not sure why the RSpec docs say you can pass an array into the include matcher, but [:a, :b, :c].include?([:a, :b]) returns false, even though [:a, :b, :c].include?(:a) and [:a, :b, :c].include?(:b) both return true. According to this SO thread a better way to check this would be:

expect(FactoryGirl.attributes_for(model).keys - csv.first.split(',').map(&:to_sym)).to be_empty

This isn't quite working, there are some differences between the parameters we require for CSV import of users and the attributes in FactoryGirl (e.g. password), so we'll have to tweak these specs to work, but that's at least going to test for what you want. Hope that helps!
