在上面的例子中,我们将日期'1990-01-01', '1992-03-05', '1988-12-10', '1995-10-11'转化为集合,并使用sortBy函数按照birthdate排序。我们从输出结果可以看出,集合中的日期已按照日期顺序进行了排序。 结论 在Laravel中,我们可以使用sortby函数按照varchar和date进行排序。我们只需要将字符串和日期转化为集合...

Previously, the storage format for Eloquent date fields could be modified by overriding the getDateFormat method on your model. This is still possible; however, for convenience you may simply specify a $dateFormat property on the model instead of overriding the method....

$query->when(request('filter_by') == 'date', function ($q) { return $q->orderBy('created_at', request('ordering_rule', 'desc')); }); 它可能看上去不是很优雅,但它强大的功能是传递参数: $query = User::query(); $query->when(request('role', false), function ($q, $role) { ...
我们可以通过SQL代码将列操作传递给称为“RAW”函数的函数，例如selectRaw、whereRaw、orderByRaw等。
