sql "LIKE" equivalent in django query

What is the equivalent of this SQL statement in django?

SELECT * FROM table_name WHERE string LIKE pattern;

How do I implement this in django? I tried

result = table.objects.filter( pattern in string )

But that did not work. How do i implement this?

Use __contains or __icontains (case-insensitive):

result = table.objects.filter(string__contains='pattern')

The SQL equivalent is

SELECT ... WHERE string LIKE '%pattern%';

contains and icontains mentioned by falsetru make queries like SELECT ... WHERE headline LIKE '%pattern%

Along with them, you might need these ones with similar behavior: startswith, istartswith, endswith, iendswith

making

SELECT ... WHERE headline LIKE 'pattern%

or

SELECT ... WHERE headline LIKE '%pattern
