34942	Add icontains support for PostgreSQL ArrayField	aminabbasov	nobody	"Django ORM for PostgreSQL ArrayField allows to make only ""contains"", and doesn't support ""icontains"", although the database itself supports this type of query.

For example, I have this Product table:

{{{#!python
class Product(models.Model):
    name = models.CharField(max_length=255)
    options = ArrayField(base_field=models.CharField(max_length=255))

    def __str__(self):
        return self.name
}}}

And only two rows in table:

||= id =||= name =||= options =||
|| 1 || First || [""foo"", ""Bar"", ""BAZ""] ||
|| 2 || Second || [""Foo"", ""Bar"", ""baZ""] ||

If I want to filter rows by options сolumn, I can make only this ORM queries:

{{{#!bash
>>> Product.objects.filter(options__contains: ""foo"")
<ProductQuerySet [<Product: First>]>

>>> Product.objects.filter(options__contains: ""Bar"")
<ProductQuerySet [<Product: First>, <Product: Second>]>
}}}

But if I want to do case-insensitive filtering, {{{Product.objects.filter(options__icontains: ""foo"")}}} wouldn't work. So, the only option to do this query, is to use {{{.extra()}}} method:

{{{#!bash
>>> Product.objects.extra(
...     where=['%s ILIKE ANY (options)'],
...     params=[""foo""],
...     )
<ProductQuerySet [<Product: First>, <Product: Second>]>
