  • u
    i've always used uuids for ids in general my end goal is to be able to say "a bucket has many columns", that's it
  • u
    (column the object, not an SQL column 😆)
  • u
    so if I want to query all of the columns for a bucket, I'd do like "get all of the columns where the column id is some specified bucket id"?
  • u
    I guess I'm still working in a prisma mindset where I'd do it the other way around: 
    someBucket.columnIds.map(id => getColumn(id))
  • s
    You'd query with something like
    Copy code
    javascript
await supabase.from('columns').select('*').eq('bucket_id', id);
  • s
    again, i don't really understand what you are trying to achieve, but perhaps you could use row level security to lock it down (assuming buckets correspond to users?)... probably not though
  • u
    yeah, that works. I was thinking that I had to set up some "official relation" but I suppose not
  • s
    How come i cant see the RLS options (I know i can do them myself) on my supabase instance?
  • s
    Nevermind, I was on the complete wrong page
  • s
    how do i query from auth.users using supabase?
  • s
    im trying to utilize the javascript api and its like it doesnt even see it
  • s
    can it not see the auth schema?
  • s
    is there a way to pump in a raw AQL query
  • s
    SQL
  • b
    Correct, for security reasons, you can't access the 
    auth
    schema from the client.
  • b
    You can create a 
    view
    or a create a 
    function
    to access 
    auth.users
    and then call the function with 
    .rpc()
    .
  • u
    Is there a way to restrict fields a user can update in a policy? For example if I add a role field to a table I would like to not allow regular users to update their own roles.
  • s
    I would probably move that to a seperate table
  • s
    e.g. 
    public.users
    table has a FK referencing 
    public.roles
    table. Then you can lock down the roles table?
  • s
    I'm starting to learn these fancy stored procedures/psql functions and was hoping for some help. I've got the below table, and I want to insert a record in it within my function... this is what I've tried but the Supabase SQL editor gives an error 
    syntax error at or near "returning"
    public.users
    Copy code
    sql
CREATE TABLE users (
  id bigint generated by default as identity primary key,
  user_id uuid references auth.users,
);
    function
    Copy code
    sql
...
insert into public.users returning id into new_user_id;
...
    Right now, all I want it to do is create a record with an auto-generated PK and a user_id of null
  • j
    you have to specify the fields you're inserting
  • j
    and the values
  • j
    insert into public.users(id, ...) values(...
  • j
    btw why dont you use the id from 
    auth.users
    directly?
  • s
    Even if it auto generates 
    id
    I need to specify? What value do I pass?
    Copy code
    sql
insert into public.users (id) values () returning id into new_user_id;
  • s
    I'm trying to set up a form submission that optionally creates a user, so have an intermediate users table
  • s
    Ok changing the insert to be:
    Copy code
    sql
insert into public.users default values returning id into new_user_id;
    gets me past that error and onto a new one 🙂
  • s
    Using the auto-generated api for my newly created function results in below error: api
    Copy code
    ts
let { data, error } = await supabase.rpc('new_job_post', {...})
    error
    Copy code
    ts
{"hint":"To call a procedure, use CALL.","message":"public.new_job_post(...) is a procedure","code":"42809","details":null}
    Oh I think it needs to be a function rather than a procedure?
  • j
    yeah i think so
  • j
    CREATE FUNCTION
    syntax
