Why this yaml file won't parse?
---
<% sensor_types = YAML.load_file('db/seed-fixtures/sensor_type.yml') %>
<% sensor_types.each do |sensor_type| %>
sensor<%= sensor_type['id'] %>:
id: <%= sensor_type['id'] %>
title: <%= sensor_type['title'] %>
unit: "<%= sensor_type['unit'] %>"
valid_min: <%= sensor_type['valid_min'] %>
valid_max: <%= sensor_type['valid_max'] %>
codename: <%= sensor_type['codename'] %>
scale_base_ten_exponent: <%= sensor_type['scale_base_ten_exponent'] %>
<% end %>
this file is used for fixtures in my tests, it is loaded by rspec from the fixtures directory.
when I try it I get: "mapping values are not allowed in this context at line 4 column 28 (Psych::SyntaxError)"
You can't load a YAML file containing ERB like a basic YAML file. Checkout this post.
What you can do instead is (in a spec initializer or a before hook):
FIXTURE_CONFIG = YAML.load(ERB.new(File.read("#{Rails.root}/path_to_your_file.yml.erb")).result)
And then use this variable in your test.
