Create sane start and end dates with nelmio\alice - doctrine

I want to create a completedDatetime that follows the datetime in the orderDatetime field.
Fixtures.yml
directive_{200..500}:
orderDatetime: <dateTimeThisYear()>
completedDatetime: '90%? <dateTimeBetween("orderDatetime", "now")>'
I used the code above in my fixtures file and got the data that follows.
Is there a way to ensure a sane result using faker data short of writing custom functions in LoadFixtures??

Since you are passing string "orderDatetime" to strtotime() function it returns 1970 year and your dateTimeBetween works like dateTimeBetween('1970', 'now'). Passing of variables is done with $orderDatetime. But if you pass such variable to dateTimeBetween(), the future dateTime might get passed which is not possible.
It only works if your order date is the past from now:
orderDatetime: '<dateTimeBetween("-200 days", "now")>'
completedDatetime: '90%? <dateTimeBetween($orderDatetime, "now")>'
If you wonna generate future dates then you need to create custom faker function for example:
public function dateTimeBetweenAfter($dateFrom, $dateTo)
{
$date = new DateTime($dateFrom->format('Y-m-d H:i:s'));
$dateTo = $date->modify($dateTo);
return FakerDateTime::dateTimeBetween($dateFrom, $dateTo);
}
and use it like this:
orderDatetime: <dateTimeThisYear()>
completedDatetime: '90%? <dateTimeBetweenAfter($orderDatetime, "+1 year")>'

Laravel - different formats for date/time query

I am learning Laravel and I have some small problem on controllers - when I use DB, the query returns date time without timezone but if I use model, the query returns full datetime.
public function test($switch)
{
//return "YYYY-MM-DDThh:mm:ss.000000Z"
if ($switch) return Position::select('id','created_at')->orderBy('id')->get();
// return "YYYY-MM-DD hh:mm:ss"
return DB::table('positions')->select('id','created_at')->orderBy('id')->get();
}
Why? What I need to dof I want "YYYY-MM-DDThh:mm:ss.000000Z" on both cases?
Thanks for solution.
thanks for advice
You should use the DB::raw
The following statement will convert the datetime value created_at from +00:00 timezone to +10:00 timezone.
You can try this
return DB::table('positions')->select(DB::raw('id',CONVERT_TZ('created_at','+00:00','+10:00'))->orderBy('id')->get();
you can set your timezone that you wants to convert it
They are the same data, probably just different classes of date and you can always format your date. Laravel utilizes Carbon date library which is excellent and should be used primarily.
If you try to print out your date class with get_class() for Eloquent Position created_at, you probably got Carbon and DB::table('positions') created_at, you probably got DateTime and that's why the value looks different (but you still got the same date).
If you want to convert your DateTime to Carbon, you can do
$newDate = new \Carbon\Carbon($position->created_at)
Thanks Anurat,
I realized this fact shortly after sending the previous question.
... but there is another 'issue' - both times are my local time - time in "YYYY-MM-DDThh:mm:ss.000000Z" is not UTC time as I expected.
I changed my function:
public function test($switch = false)
{
$data = Position::selectRaw('id, created_at, UNIX_TIMESTAMP(created_at) unix')->orderBy('id')->get();
foreach ($data as $d) {
$conv = new \DateTime($d->created_at);
$d->conv = intval($conv->format('U'));
$d->diff = $d->conv - $d->unix;
}
return $data;
}
... and result is
0
id 1
created_at "2021-03-18T12:36:59.000000Z"
unix 1616067419
conv 1616071019
diff 3600
As you see, the difference is 1 hour (as my timezone offset). Where is a problem?
Thanks.

How to add minutes to to a date in laravel

There are few ways that I can do this using PHP but I could not find a way to do that using laravel specific way.
I have a time that is coming from database in below format: Y:M:s
ex: 05:15:00
This is what I want to do:
add 30 minutes to that date, according to above example result should be: 05:45:00
Below is my current code and I want to add 30min to $endTime:
//get database value according to selected date
$allocatedDateQuery = DB::table('appointments')->where('date', $request->date)->get();
//loop throug every record to get time
foreach ($allocatedDateQuery as $value) {
$time = $value->time;
$endTime = $time;
}
I just got a perfect solution from here.
Use Carbon extention to simply acheive that.
What you have to do is parse your time to Carbon object and then you can use addMinutes() to do that and then you can format() if you want:
foreach ($allocatedDateQuery as $value) {
$time = Carbon::parse($value->time);
$endTime = $time->addMinutes(30);
$allocateValidateMessage .= Carbon::parse($value->time)->format('H:i') . ' - ' . $endTime->format('H:i') . ' ';
}
Usually I use php's date, you can give this a try
Date("Y:M:s", strtotime("30 minutes", strtotime($value->time))
That is converting your time into a string, adding 30minutes to it and converting it to the date format of your desire
Since you said you are grabbing the date from the database I am assuming you are also using Eloquent to query from the database.
You can use Eloquent Mutator Method in your Database Modal Class to mutate the data like this:
public function getAppointmentsAttribute($value) {
return Date("Y:M:s", strtotime("30 minutes", strtotime($value->time)));
}
You can even add another attribute without mutating the original value using Attribute assignments as well. This method caches your query and reduces database calls. Since you do not need to run local loops on the record your code is much cleaner.

Laravel: Check if time + 4 hours has passed

I store in my database a date format like this:
2017-02-22 16:55:40
I added it to my database like this:
Carbon::now();
I need to check if 4 hours passed since this date.
How I can do this? I couldn't figure out how I can convert this format into Carbon or timestamp.
If you are using Laravel and the date is a Carbon instance from a Model you have access to the whole Carbon API.
You can use the Difference API of Carbon for this specific purpose.
echo $model->thedate->diffInHours($now, false);
If your model does not threat the date as a carbon instance you can cast it by adding the date to the dates array of the current model like so
protected $dates = [
'field_name',
];
Check out Date casting for more information
Update with an explicit example
$user = User::first();
// This will return the difference in hours
$user->created_at->diffInHours(Carbon\Carbon::now(), false);
You can convert it to a Carbon object with:
Carbon::parse('2017-02-22 16:55:40');

how to select one month back records from data base in laravel

how select one month back records from current date from database in laravel. I am trying this code.
This is controller code.
class LoginHistoryController extends Controller {
public function index()
{
$login_history = LoginHistory::where('login_date','BETWEEN', '(CURDATE() -
INTERVAL 10 DAY) AND CURDATE()' )->get();
}
}
but i am getting error.
I will have a approach something like this. First I will calculate the date like
$today = date('Y-m-d');
$date = date_create($today);
date_sub($date, date_interval_create_from_date_string("30 days"));
$beforeOneMonth = date_format($date, "Y-m-d");
You should have the intended value in $beforeOneMonth by now. Now you can compare it in anyway you like whether you use IN operator or >=. For eg.
$login_history = LoginHistory::where('login_date','>=', $beforeOneMonth)->get();
Give it a try. If you are storing date in some other format, you can do your own tricks to format the date and do the thing
Another way to do it would be with whereRaw:
$login_history = LoginHistory::whereRaw(
'login_date BETWEEN (CURDATE() - INTERVAL 10 DAY) AND CURDATE()'
)->get();
Note that whereRaw has the side effect of making your code less portable since you're using SQL that might be specific to your database server. But sometimes you just can't do what you would like using the query builder.

Convert unix timestamp to normal Date in Json

I am using laravel 5.0. I am getting data from controller as json. I am having value like this.
{"timstamp_date":"1434360957"},
I need to convert this unix timestamp value as Normal Date Like (15-06-2015) or (15-March-2015).
I have used Date(timstamp_date) but it is showing current time only. Not my timstamp date
You could use:
date("d-m-Y H:i:s", 1434360957);
EDIT
You could try;
var dateTime = new Date(1434360957*1000);
var formatted = dateTime.toGMTString();
https://jsfiddle.net/sp57Lnpf/
Use the date function. You need to specify the format as the first parameter:
date("d-m-Y", $timestamp_date)
http://php.net/manual/en/function.date.php
Laravel also comes with Carbon you could use that if you wanted to for further manipulation of the data if you so required it.
