I'm trying to make a simple scope for a model which has "end_time" as a dateTimeTz() column in Laravel 5.8. I'm using:
public function scopeActive($query)
{
return $query->whereNull('end_time')->orWhere('end_time', '>', Carbon::now());
}
But this is only comparing the date element of the end_time column, and giving me everything ending strictly after today, when I want anything ending later on today as well.
What is the correct way of going about this?

I`ve got code that shows all of the placements for a user. Is there a way to narrow this down to only show placements that are in the future? I've tried to do this using where and carbon::now to no avail.
My current code to show all of the placements :
$placements = Auth::user()->placementsAuthored;
$placements->load('keystage', 'subject', 'dates');
Placements Authored connection to connect a user to a placement :
public function placementsAuthored()
{
return $this->hasMany(Placement::class, 'author_id');
}
My attempt at trying to do this. I get no errors but the code doesn't work. It doesn't seem to take any effect of my where clause any ideas?
$placements ->where('date','>',Carbon::now()->format('Y-m-d'));
After a bit of tweaking, I found that this works but I don't understand why this works and the above doesn't. In my mind, they do the same but this is a longer way of doing it. Any idea why this works and the above doesn't?
// Only load future placements
$placements = Placement::whereHas( 'dates',
function ($q) {
$user_id = Auth::user()->id;
$q->where('author_id', $user_id)->where('date','>=' ,Carbon::now()->format('Y-m-d'));})->get();
You should take a different name for the date column because the date keyword is already reserved in the PHP function this is not a standard way
Im new to laravel and im tryin to learn the fundamentals of it. My question is how can I display all the registered users that is registered only on the current month.
$from = now()->startOfMonth(); // first date of the current month
$to = now();
$usersRegisteredThisMonth = User::whereBetween('created_at', [$from, $to])->get();
There is a simple way of doing it.
Just use this code
User::whereMonth('created_at', now()->month) // checking if the month of created_at is current month
->whereYear('created_at', now()->year) // checking if the year of created_at is current year
->get();
This line will give you Users from current month.
Nobody explained that these queries might be put in user model with local scope scopeWith magic method. I assume you read docs from top to bottom.
Simple example:
public function scopeRegisteredLastMonth($query){ return $query->whereBetween... }
Laravel Local Scope
You can specyficy additional arguments for this method.
The final call in controller will look like this:
$lastMonthUsers = User::registeredLastMonth()->get();
This function should be set to something like 'public function withRegisteredBetween($query, $date_start, $date_end) and return query based on date range.
PS: Don't use DB:: when you can use Model::method() or Model::query()->method()
PS2: for date management I advise you to install carbon, it's an additional addon - sometimes it's easy, sometimes not, overall not bad.
You could use the users table with a whereBetween clause like this:
$from = date('2022-01-05 00:00:00');
$to = date('2022-31-05 00:00:00');
$usersRegisteredThisMonth = DB::table('users')->
whereBetween('created_at', [$from, $to])->get();
I have two forms; the first is the form formers with two fields (name, firstname).
I also have the form trainings with two fields (date_sitting, fk_former).
My problem, if I want to add the other sitting today (07/07/2019), I would like to see only the formers who have no training today.
Here, I retrieve a former who has a sitting today.
Do you think it's possible to get only the formers who have no of sitting for now?
Edit: 10/07/2019
Controller Training
public function index()
{
$trainings = Training::oldest()->paginate(5);
$formersNoTrainingToday = Training::whereDate('date_sitting', "!=", Carbon::today())
->orWhere('date_sitting', null)->get();
return view('admin.trainings.index', compact('trainings', 'formersNoTrainingToday'))
->with('i', (request()->input('page',1) -1)*5);
}
And
public function create()
{
$formers = Former::all();
return view('admin.trainings.create', compact('formers','trainings'));
}
I would like to see only the formers who have no training today.
Sure - you can determine your correct list of candidates to show by using the following query:
$formersNoTrainingToday = Training::whereDate('date_sitting', "!=", Carbon::today())
->orWhere('date_sitting', null)->get();
This should work... but it assumes a few things within your code / db. If this fails, consider a few options to replace the whereDate section above:
Using where:
->where('date_sitting', '!=', \Carbon::today()->toDateString())
Using formatted date if that column on the DB is a different format than Carbon:
->whereDate('date_sitting', "!=", Carbon::now()->format('m/d/Y'))
If you're not using Carbon for some reason, you can try the raw query route for today:
->whereDate('date_sitting', "!=", DB::raw('CURDATE()'))
Bottom line, here are a number of ways to get close to this. But you may need to tweak this on your own to suit your needs. You may need to take Timezone or some hours of difference into account, so you may need to add a range or buffer. But the above should get you close if not all the way there.

I want to return values in my model based on dates but not sure how to?
Logic
calculate the date that post has published + 7 days after that and return true or false.
example
Let say I want add new label in posts from the date that post published till 7 days after that, and in the day 8th that new label be removed.
How do I do that?
Update
I ended up with something like this in my model currently
public function isNew($query){
return $query->where('created_at', '<=', Carbon::now()->toDateTimeString());
}
but it returns Undefined variable: isNew in my blade.
please give me your suggestions.
Are labels stored in a separate table from your posts? You could use 'effective dating'. Have indexed 'show_at' and 'hide_at' fields in your labels table. Have entries there get created as soon as the post does. You could use database triggers to do this, or model observers. And when querying for all labels related to a given post, make sure they're between those dates (or those dates are null).
For a more simple solution, you could do a whereRaw('CURRENT_DATE <= DATE_ADD(dateFieldName, INTERVAL 7 DAY)'). If timezones are a factor, you could use the CONVERT_TZ() function, though it's generally good practice to store everything in UTC to avoid those issues.
I would recommend you make use of Carbon:
https://carbon.nesbot.com/docs/#api-difference
That link should help a lot but to point you in the correct direction, you should be able to do a comparison:
I assume you DB date is held in ISO (Y-M-D, eg: 2019-01-07)
$date= Carbon::createFromFormat('Y-m-d', $dateFromDB);
if($date->diffInDays(Carbon::now() < 8){
Code for Add Label here
}
Or if you are using timestamps:
$date= Carbon::createFromTimestamp($dateFromDB);
if($date->diffInDays(Carbon::now() < 8){
Code for Add Label here
}
Solved
thanks for all the helps I solved my issue with code below:
public function getisNewAttribute(){
$now = Carbon::now();
return Carbon::parse($now) <= Carbon::parse($this->created_at)->addDays(7);
}
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.
