Good day, I'm new to laravel and have been attempting to figure out how on earth to do a multi-way relationship. I could be doing this completely wrong, so do bear with me.

So currently my db structure looks a little like this:

- Users
   -id
   -username

-Trades
  -id
  -user_id

-Trade_Items
  -id
  -trade_id
  -item_id

-Item_db
  -id
  -image etc

Now, what I am trying to achieve is to be able to access all of the information to that makes up a User's 'trade', i.e I get all the user's trades, find out the trade items and return the information from the item_db.

Each user can have many trades, each trade can have many items and those items from Trade_Items relate to one section of the Item_db.

So, what I currently have is an absolute mess, I can post it but I'm not sure it will help very much. If someone could at least point me in the right direction, I would be extremely grateful!
