Undocumented required folders, nested dashboards not working

[charlesdunbar]

I really hope I'm doing something horribly wrong here, but I've been trying to get nested dashboards working and am running into issues along the way.

Here's the config file:

:graphite: http://graphite.server.url
:templatedir: /opt/gdash/graph_templates/

:username: admin

:password: secret

:options:
:title: My Dashboard
:prefix: ""
:refresh_rate: 60
:graph_columns: 2
:graph_width: 500
:graph_height: 250
:interval_filters:
- 🏷️ Last Hour
:from: -1hour
:to: now
- 🏷️ Last Day
:from: -1day
- 🏷️ Last Week
:from: -1week
- 🏷️ Last Month
:from: -1month
- 🏷️ Last Year
:from: -1year
:intervals:
- [ "-1hour", "1 hour" ]
- [ "-2hour", "2 hour" ]
- [ "-1day", "1 day" ]
- [ "-1month", "1 month" ]
- [ "-1year", "1 year" ]

Following the picture of the example directory in the README, my tree looks like:

graph_templates
`-- virtualization
    |-- dom0
    |   |-- dash.yaml
    |   `-- switch.graph
    `-- kvm1
        |-- dash.yaml
        `-- switch.graph

However, when I hit gdash, I get: "Internal Server Error" with the error log saying:

Apparently need the dashboards folder. Not exactly mentioned that that directory is required in the example directory structure.

New tree:

graph_templates
|-- dashboards
`-- virtualization
    |-- dom0
    |   |-- dash.yaml
    |   `-- switch.graph
    `-- kvm1
        |-- dash.yaml
        `-- switch.graph

Still internal server error. This time: Errno::ENOENT - No such file or directory - /opt/gdash/graph_templates/node_templates:

Not mentioned anywhere I can see.

graph_templates
|-- dashboards
|-- node_templates
`-- virtualization
    |-- dom0
    |   |-- dash.yaml
    |   `-- switch.graph
    `-- kvm1
        |-- dash.yaml
        `-- switch.graph

Gdash loads!

virtualization isn't an option on the top menu, nor does anything appear. Maybe I need to put virtualization in the dashboards folder.

graph_templates
|-- dashboards
|   `-- virtualization
|       |-- dom0
|       |   |-- dash.yaml
|       |   `-- switch.graph
|       `-- kvm1
|           |-- dash.yaml
|           `-- switch.graph
`-- node_templates

I'll save the screenshot, but it's the same blank as before. Maybe I need to put them directly under dashboards.

graph_templates
|-- dashboards
|   |-- dom0
|   |   |-- dash.yaml
|   |   `-- switch.graph
|   |-- kvm1
|   |   |-- dash.yaml
|   |   `-- switch.graph
|   `-- virtualization
`-- node_templates

Success! Except I don't know where/what's causing node_templates to be needed, dashboards to be needed, or how to have nested directories like the readme says it supports. Any ideas? For the installation, I followed the bundle install steps found in #45, not sure if that's related at all.
