Django model validate date and datetime ranges

Django model validate date and datetime ranges

it should still fix some issue It's better to use a form to validate the time range, form has already built in function clean() to fit your needs:
code :
class PriceOptionForm(forms.ModelForm):
    # some normal ModelForm setup goes here
    def clean(self):
        cleaned_data = super(PriceOptionForm, self).clean()
        from_time = cleaned_data.get("from_time")
        end_time = cleaned_data.get("end_time")

        if from_time and end_time:
            if end_time < from_time:
                raise forms.ValidationError("End time cannot be earlier than start time!")
        return cleaned_data

Validate date and datetime with Bootstrap datetime picker, Jquery validation plugin in an Asp.Net MVC4 application

seems to work fine I am currently developping a MVC Asp.Net 4.6 WebApp with Bootstrap 3.1.1, Eonasdan datetime picker v4.7.14 and jquery validation plugin v1.14.0. , You can overrides the date method of the Jquery.validator plugin :
code :
(function () {
    // overrides the jquery date validator method
    jQuery.validator.methods.date = function (value, element) {
        // All dates are valid....
        return true;
    };
})(jQuery);
(function () {
    // overrides the jquery date validator method
    jQuery.validator.methods.date = function (value, element) {
        // We want to validate date and datetime
        var formats = ["DD/MM/YYYY", "DD/MM/YYYY HH:mm"];
        // Validate the date and return
        return moment(value, formats, true).isValid();
    };
})(jQuery, moment);

help you fix your problem There are 2 solutions I can think off.
First one is the hardest on: you could implement your own FieldReflector class and make it able to parse all data formats you mentioned. For this number of formats this may be the best way.
Django AttributeError: type object 'datetime.datetime' has no attribute 'datetime'

Django AttributeError: type object 'datetime.datetime' has no attribute 'datetime'

This might help you You used from datetime import datetime which means your datetime name is already pointing to datetime.datetime. If you try to access datetime.datetime you will end up accessing datetime.datetime.datetime which doesn't exist.
You should use just import datetime instead, and in your code use datetime.datetime and datetime.timedelta, but if you still want to use from datetime import datetime, timedelta, you have to change all datetime.datetimes in your code to say only datetime and datetime.timedelta to say only timedelta.
How to validate forms using django and how many ways to validate form using django

How to validate forms using django and how many ways to validate form using django

it should still fix some issue Django can handle server-side validation for you. The two examples you posted above are two valid ways to do this and they are almost correct. You just need to pass some data to your form to validate. So if you change your view to
code :
# Create your views here.
def index(request):
    form = validform(request.GET or None)
    return render(request,'index.html',{'form':form})
<input type="text" pattern="/hari/">
def __init__(self, *args, **kwargs):
    super().__init__(*args, **kwargs)
    self.fields['firstname'].widget.attrs.update({'pattern': '/hari/'})
