Dashboard Excel integration

[thefixxxer75]

Hi all,
I've tried to integrate some xls data with dashboard, using some old post and modifying "sample.rb".
When I start "smashing start", I get the following error

bundler: failed to load command: thin (/usr/local/bin/thin)
LoadError: cannot load such file -- roo

I've the spreadsheet.xls in the root dir and all the permissions are fine.
I've installed roo and roo-xls via gem...but seems not working yet.
Please, someone has already passed through that?
Thanks in advance for your support

I have this working...can you post your sample.rb & Gemfile please.

What version of excel is the file created in & what is its file extension xls,xlsx, xlsm etc?

[thefixxxer75]

sample.rb

#!/usr/bin/env ruby
require 'roo'

SCHEDULER.every '2s' do
file_path = "/path/to/spreadsheet.xls"

def fetch_spreadsheet_data(path)
s = Roo::Excel.new(path)
send_event('valuation', { current: s.cell('B',49) })

end

module Handler
def file_modified
fetch_spreadsheet_data(path)
end
end

Gemfile

source 'https://rubygems.org'

gem 'smashing'
gem 'nagiosharder', :git => 'https://github.com/railsmachine/nagiosharder.git'

Remove this if you don't need a twitter widget.

gem 'twitter', '>= 5.9.0'

[thefixxxer75]

extension is xls, done with LibreOffice Calc

[ghost]

I'll assume that an xls file created in LibreOffice is 100% compatible with this solution, I use this method with Excel created files.

Additionally I'm assuming that you have read/write permissions to the location of your xls file.

Make a backup of your smashing folder.

Now replace the contents of your Sample.rb with the following:

Copy from below this line

require 'roo'
require 'roo-xls'

SCHEDULER.every '2s', :first_in => 0 do |job|
file_path = "#{Dir.pwd}/THIS_IS_THE_PATH_LOCATION_TO_THE_XLS_FILE/YOUR_FILENAME.xls"

s = Roo::Excel.new(path)
send_event('valuation', { current: s.cell ('B',49) })

end

module Handler
def file_modified
fetch_spreadsheet_data(path)
end
end

to above this line

Add the next 2 lines to your Gem file

gem 'roo', '~> 2.1.0'
gem 'roo-xls'

At the command line run (without the quotes) "bundle"

Check for errors...if you have any post them back to this thread. Otherwise, start your dashboard.....fingers crossed.

thanks for your reply!!
I've tried but here's results

any idea about it? Syntax seems fine or am I wrong?
thx in advance

you're getting close...

I'm not on a system I can test this but I think there is a formatting problem, aka something got muddled with the copy and paste. Replace send_event('valuation', { current: s.cell ('B',49) })

with
send_event('valuation', { current: s.cell ('B',49) })

Yeah I know it looks exactly the same but humor me....

[thefixxxer75]

same error here...I don't know where the problem is.
I'm pointing to the right path of the xls file but seems that this sample.rb has something wrong. It's quite weird...

[ghost]

I'll take a closer look tomorrow and post back...

[ghost]

sorry for the delay. Try this line in your .rb file instead of the line that is there. I had eyeballed my own job file with multiple cells in one 'send_event', needed to tidy that up.

send_event('valuation', {current: s.cell('B',49)})

[thefixxxer75]

thanks sooooooooooooo much for your time. Now error is changed
Smashing start but this log

scheduler caught exception:

undefined local variable or method path' for main:Object Did you mean? patch /home/xxxxx/xxxxxxxxx/jobs/sample.rb:7:in block in <top (required)>'
/var/lib/gems/2.3.0/gems/rufus-scheduler-2.0.24/lib/rufus/sc/jobs.rb:230:in trigger_block' /var/lib/gems/2.3.0/gems/rufus-scheduler-2.0.24/lib/rufus/sc/jobs.rb:204:in block in trigger'
/var/lib/gems/2.3.0/gems/rufus-scheduler-2.0.24/lib/rufus/sc/scheduler.rb:430:in `block in trigger_job'

Maybe refer to this one?

file_path = "#{Dir.pwd}/THIS_IS_THE_PATH_LOCATION_TO_THE_XLS_FILE/YOUR_FILENAME.xls"

[ghost]

yes exactly.

in what directory is your excel file? Wherever that is you need to replace what I have written in CAPITAL letters with it.

e.g.
/home/howardsternisbatman/myfile.xls

[thefixxxer75]

my excel file is in /home/username/dashing/myfile.xls.
Is it correct?

[ghost]

if you are asking me is that path as you have written it is correct for you, the answer is no. I'm sensing you are not familiar with Linux's file/folder structure. You need to read up on it since where you are stuck now has nothing to do with Smashing.

This might help

You're close, solve the file path and you should be all good.

[thefixxxer75]

Thanks mate! I'm quite confident with folder structure. My only "concern" is that I've understand - reading a post - the the spreadsheet should be present in the dashboard/smashin "root" dir (so /home/xxxxx/smashing/). My fault :) I'll try and send u a feedback. Thanks so much

[thefixxxer75]

error persist. File moved as suggested.

undefined local variable or method path' for main:Object Did you mean? patch /home/xxxxx/xxxxxxxxx/jobs/sample.rb:7:inblock in <top (required)>'

[ghost]

I have my xls located in

/home/howardsternisbatman/mydashboard/xls/myfile.xls

As long as the file is somewhere within the dashboard file structure I don't see why this wouldn't work.
