Laravel 一对多关系不起作用 - 返回递归

Question

I am developing an application with Laravel 8 and I ran into very strange behavior.

I have a Model called "Organisation", this Organisation has many Users (Model from Jetstream).

I did the relationship as usual:

In Organisation Model:

    public function users()
    {
        return $this->hasMany(User::class);
    }

In User Model:

 public function organisation()
    {
        return $this->belongsTo(Organisation::class);
    }

I have a field on the users table called organisation_id which is declared in the migration as such:

 $table->foreignId('organisation_id')->nullable()->constrained();

I checked the DB, everything is filled in, with no null values.

Expected result: If I call

  $testUser=User::find(1);
  $testOrg=$testUser->organisation();

I will get the organization object.

Actual result: I receive a veeeeery log object, stating something including RECURSION , instead of the organization I want. Is this an error regarding the foreign key? The User model also has a belongsToMany Relationship to a different model, is this in the way of the standard belongsTo?

EDIT I can receive the organization when calling

  $testUser=User::with('organisation')->find(1);

But this is not the clean Laravel way I want to work with.

I debugged the query with $testOrg=$testUser->organisation()->toSql();and it displayed me: string(60) "select * from organisations where organisations . id =?",

So the "where" is wrong?

Any hints or help would be very appreciated

Here is some of the output: (whole output is too long)

Try this:

 $testUser=User::with('organisation')->find(1);

If you want to continue your way then update to this:

$testUser=User::find(1);
$testOrg=$testUser->organisation;
