The reason why the second relation is not allowed is that this package should apply all those clauses on the join clause, eloquent use all those clauses isolated with subqueries NOT on join clause and that is more simpler to do.
You can add not allowed clauses on relations and use them in the normal eloquent way, but in these cases, you can't use those relations for join queries. Other clauses like whereHas, orderBy etc. Clauses where and orWhere can only have these variations. Relations that you want to use for join queries can only have these clauses : where, orWhere, withTrashed, onlyTrashed, withoutTrashed. arguments are the same as in default eloquent orWhereNotIn()Īllowed clauses on BelongsTo, HasOne and HasMany relations on which you can use join clauses on the query. arguments are the same as in default eloquent orWhereIn(). arguments are the same as in default eloquent whereNotIn(). WhereNotInJoin($column, $values, $boolean = 'and') arguments are the same as in default eloquent whereIn(). WhereInJoin($column, $values, $boolean = 'and', $not = false) arguments are the same as in default eloquent orWhere(). arguments are the same as in default eloquent where(). WhereJoin($column, $operator, $value, $boolean = 'and') $aggregateMethod argument defines which aggregate method to use ( SUM, AVG, MAX, MIN, COUNT), default MAX. $column and $direction arguments are the same as in default eloquent orderBy(). OrderByJoin($column, $direction = 'asc', $aggregateMethod = null) $leftJoin use left join or inner join, default left join. JoinRelations($relations, $leftJoin = null) New clauses for eloquent builder on BelongsTo and HasOne relations : Options are : SUM, AVG, MAX, MIN, COUNT Usage Currently available relations for join queries The second way is by eager loading the relationship with an order by statement.Select "sellers".*, MAX("locations". Now, whenever you call $company->users (as a collection), or $company->users() (as a query builder), the users will be automatically ordered by their name. Return $this->hasMany(User::class)->orderBy('name')

The way to do this is different depending on the relationship type.
For example, maybe we want to order some users by the name of their company, which is in a separate companies table.
