Extend inner join to fetch not yet connected rows also - Mailing list pgsql-general

I have craftsmanships table which has (id, name) and users table (id, email, ..). When a user has some craftsmanships,
theyare stored inside the contractor_skills(user_id, craftsmanship_id, id) table. 

What I want here is that to list all the available craftsmanships with id, name and has column. I can get now only
thosecraftsmanships that a specific user has,  

SELECT
    craftsmanships.id,
    craftsmanships.name,
    TRUE as has
FROM
    "craftsmanships"
    INNER JOIN "contractor_skills" ON "contractor_skills"."craftsmanship_id" = "craftsmanships"."id"
    INNER JOIN "users" ON "users"."id" = "contractor_skills"."user_id"
WHERE (contractor_skills.user_id = 8)
ORDER BY
    "craftsmanships".”id"

——————
 id |  name   | has
----+---------+-----
  1 | paint   | t
  2 | drywall | t
(2 rows)

But I want to list all craftsmanships and has column should have `t` when user_id #8 has it, else `f`. How can I extend
this    query?
