Rails load seed - feedback

Question

I have a admin page on my site which allows me to load seeds by clicking a link.

it just calls:

Rails.application.load_seed

Problem is, there is no feedback that this is happening - I would like to see the seed output somehow on the page (the same as if ran in the command line).

Is there a way to do this when the link is clicked?

If you care about the page reloading, you could use jquery to do an ajax post request to a route, run the script (it doesn't need to be in the seed file--you could run it in the controller action you create) you're running to add data, and then in your success callback append the results.

does this mean the output would continuously be displayed on the screen, the same as in the console? I would like user to see it as it happens.. – user3437721 Mar 07 '16 at 21:45
The user could see it happen. If you want it to be really fast, like a stack trace...you might want to break it up into multiple ajax requests, depending on how much data we're talking about. – toddmetheny Mar 07 '16 at 22:05

If by 'output' you mean messages printed to standard output (e.g. using puts in the seeds file), you might grab the output in the controller using the code from this SO answer):

# controller:
@output = with_captured_stdout { Rails.application.load_seed }

But this will only display after the load finishes, you won't get any info during the process. If you require that, I think you'd need some streaming techniques.
