Resolving the url to a results file of a simulation · Wiki · Gateways / awesim-documentation

1. On the workflow model add staged_dir_relative_path:

# Get path to staged simulation directory relative to dataroot
# i.e. given staged_dir of
#
#     /path/to/dataroot/containers/12
#
# this method returns
#
#     containers/12
#
# WARNING: Assumes staged_dir is inside dataroot!
#
# @return [Pathname] path to staged_dir relative to dataroot
def staged_dir_relative_path
-  Pathname.new(staged_dir).relative_path_from(AwesimRails.dataroot)
+  Pathname.new(staging_target_dir_name).join(Pathname.new(staged_dir).basename)
end

2. files_path is a helper provided to build URLs to files under the dataroot of the user. See https://github.com/AweSim-OSC/awesim_rails#filesrackapp for details. Add a model specific helper to build a URL, prepending the files_path URL. An example from ContainerFillSim:

module ContainersHelper
  # URL path helper
  def container_results_path(container, path)
    Pathname.new(files_path).join(container.staged_dir_relative_path, path).to_s
  end
end

3. Use the helper in your views. In this example we iterate over each step of the container and display the corresponding image for each:

<% (0..@container.steps).each do |i| %>
<div class="item <%= 'active' if i == 0 %>">
  <%= image_tag container_results_path(@container, "images/t#{sprintf '%02d', i}.png") %>
</div>
<% end %>
