Question

Cannot seems to figure out how I can post a query(json) array to a rails controller#action

I have just like

var myarray = []; ( with values )

My controller action I want to post to:

def process
end

Everywhere I find answers on how to get JSON -> Jquery
But Ill need the other way around. Anyone knows how to do this? Can’t be that hard?!

Answer 1

There’s probably a few ways to do this, but here’s one. Use some JS like this to post to your controller:

var target = "your-action-url";
var myarray = [1,2,3,etc];
$.ajax({
    type: 'get',
    url: target + '?order='+myarray.join(',') ,
    dataType: 'script'
});

Then, in your controller:

data = params[:order].split(',')

Now you have an array that matches what you had in javascript.
