I have an application that depends on making web service calls in its controller to fetch data. I want to add a feature where the page automatically refreshes the content, that is calls the action based on some set period of time. I've found many posts that hint around my problem, and I have tried setInterval
which, puzzling to me, fired twice for every update. Here is the code for that:
$(document).ready(
function(){
var loader = function(){
$('.container').load('/dashboard/index');
};
setInterval(loader, 3000);
});
I get the feeling this is an ajax issue, but I don't have a trigger event to signal the update. Any help is appreciated.
My Controller code:
class DashboardController < ApplicationController
include ActionView::Helpers::NumberHelper
include FakeMaker
def index
@reports = fake_maker("report", 22)
@workstations = fake_maker("workstation", 8)
@data_sources = fake_maker("data_source", 2)
end
end
The FakeMaker class
module FakeMaker
SOURCE_A = "A"
SOURCE_B = "B"
TYPES_A = Faker::Lorem.words(num = 10)
TYPES_B = Faker::Lorem.words(num = 4)
def fake_maker(type, count)
fake = []
case type
when "report"
count.times { fake << fake_report }
when "workstation"
count.times { fake << fake_workstation }
when "data_source"
fake = fake_data_source
end
fake
end
def fake_report
report = { source: [SOURCE_A, SOURCE_B].sample,
count: number_with_delimiter(Faker::Number.number(5), :delimiter => ',') }
report[:type] = report[:source] == SOURCE_A ? TYPES_A.sample : TYPES_B.sample.capitalize
report
end
def fake_workstation
{ name: Faker::Lorem.word,
downloaded: number_with_delimiter(Faker::Number.number(3), :delimiter => ','),
available: number_with_delimiter(Faker::Number.number(5), :delimiter => ','),
last_connect: Random.rand(10.weeks).ago.strftime("%Y-%m-%d %H:%M:%S") }
end
def fake_data_source
data_sources = []
["A", "B"].each do |source|
data_sources << { type: source,
name: Faker::Internet.url,
status: ["UP", "DOWN"].sample }
end
data_sources
end
end
