Java 303 / 349 start date before end date validation


Java 303 / 349 start date before end date validation

wish of those help Is there a better way of writing a Java validator which ensures that a start date is before an end date than writing a class level ConstraintValidator in the following manner: , One way would be to add an interface to MyBean
code :
public interface StartEndDateable {
   public LocalDate getStartDate();
   public LocalDate getEndDate();
}

public class MyBean implements StartEndDatable {
...
public class StartBeforeEndDateValidator implements ConstraintValidator<StartBeforeEndDateValid, StartEndDatable> {

    @Override
    public void initialize(StartBeforeEndDateValid annotation) {
    }

    @Override
    public boolean isValid(StartEndDatable bean, ConstraintValidatorContext context) {
        final LocalDate startDate = bean.getStartDate();
        final LocalDate endDate = bean.getEndDate();

        return !startDate.isAfter(endDate);
    }
}

Hope this helps Convert the values into a Date object. Then you can use it to compare, eg. convert to Unix timestamp or something...
See here for more info on Date:https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Date
code :
<input value="" class="validate[required,funcCall[checkDates]]" type="text" id="startdate" name="startdate" />
<input value="" class="validate[required,funcCall[checkDates]]" type="text" id="enddate" name="enddate" />
var checkDates = function(field, rules, i, options) {
    // Do your date comparisons here between startdate and enddate values
};
<input value="" class="validate[required,past[#enddate]]" type="text" id="startdate" name="startdate" />
<input value="" class="validate[required,future[#startdate]]" type="text" id="enddate" name="enddate" />

I hope this helps . I am doing a program to filter data between two dates, Starting date and End Date. In my controller I have this : , The Controller :
code :
 public ActionResult List(DateTime startdate, DateTime enddate) 
        {


                List<Card> cards = new List<Card>();

                using (var db = new CardDBEntities())
                {

                    var cardr = (from c in db.Cards
                                 join d in db.RegistrationDTs
                                 on c.CardId equals d.CardId
                                 where d.RegistrationDateTime >= startdate &&
                                       d.RegistrationDateTime <= enddate
                                 select new eReader1.Models.Model
                                 {
                                     CardId = d.CardId,
                                     Description = c.Description,
                                     RegistrationDateTime = d.RegistrationDateTime
                                 }).OrderByDescending(x => x.RegistrationDateTime).ToList();


                    //WebGrid grid = new WebGrid(cardr);

                    //ViewData["cardr"] = cardr;



                    return View(cardr);
                }

I wish this help you You can make the simple helper function that check the date validation.
code :
    checkDateValidation(startDate, endDate) {
        // check the dates
        if ((new Date(startDate) > new Date(endDate)) || (new Date(endDate) < new Date(startDate))) {
          // set date error validation true 
        } else {
          // null or false date error validation 
        }
      }
Date Validation --> end date must be greater than start date

fixed the issue. Will look into that further You can override the Model.clean(..) method [Django-doc] for this. If you use a ModelForm [Django-doc], then it will automatically call .clean() on the model instance to check if the constraint is satisfied.
code :
from django.db import models
from django.utils import timezone

class MyModel(models.Model):
    start = models.DateTimeField()
    end = models.DateTimeField()

    def clean(self):
        super().clean()
        if not (timezone.now() <= self.start <= self.end):
            raise ValidationError('Invalid start and end datetime')
# since Django-2.2

from django.db import models
from django.db.models import F, Q
from django.db.models.functions import Now

class MyModel(models.Model):
    start = models.DateTimeField()
    end = models.DateTimeField()

    def clean(self):
        # ...
        pass

    class Meta:
        constraints = [
            models.CheckConstraint(
                check=Q(start__lte=F('end'), start__gte=Now()),
                name='correct_datetime'
            ),
        ]
