I\'m creating a website in which I will be managing users and their permissions. I am looking to implement user roles, and can\'t seem to wrap my head around how things shou

Answer 1

We have managed with two table using json datatype so we does not need any repeating entry like

Role_ID Permission_ID
1       1    
1       2 

Role Table

id, role_name
'1', 'read'
'2', 'write'
'3', 'update'
'4', 'all'

User Table

id,   name,   role_assign, role_type
'1', 'arjun', '[1, 2]',    'admin'
'2', 'dhruv', '[3, 4]',    'user'

Query

SELECT u.id,r.role_name,u.name FROM test.users u inner join
test.role r on JSON_CONTAINS(u.role_assign, cast(r.id as json));

Output

id,  role_name, name
'1', 'read',   'arjun'
'1', 'write',  'arjun'
'2', 'update', 'dhruv'
'2', 'all',    'dhruv'
