wish helps you Use Enumerable#all? with a block. Integer numbers are instances of class Integer in ruby. [1, 2, 3].all? {|i| i.is_a?(Integer) } # => true
[1, 2, 3, '4'].all? {|i| i.is_a?(Integer) } # => false

Creating new arrays from an existing array that holds values with dates
Date : March 29 2020, 07:55 AM
I hope this helps you . It is unclear from your question exactly what kind of result you are trying to achieve, but here is a function that will give you an array of arrays, one array for each time value: var map = {}, i, time, temp, results;
for (i = 0; i < x.length; i++) {
time = x[i].time;
if (time in map) {
// add this item to the array we already have for this time
map[time].push(x[i]);
} else {
// create a new array for this time and put it in the map
temp = [];
temp.push(x[i]);
map[time] = temp;
results.push(temp);
}
}
// here the variable results is an array of arrays, one for each time value

wish helps you I'm working with someone else's CakePHP code, with minimal knowledge of PHP, so this may be a very basic question. , Replace those with these three: 'SUM(CASE PanelPref.panel_rating_id WHEN 3 THEN 1 ELSE 0 END) AS rated_three',
'SUM(CASE PanelPref.panel_rating_id WHEN 2 THEN 1 ELSE 0 END) AS rated_two',
'SUM(CASE PanelPref.panel_rating_id WHEN 1 THEN 1 ELSE 0 END) AS rated_one'

vec.push(i);
}
document.write("<br/>" + vec);
