How to bind a user to specific tables in a database?

Question

Laravel

Here I am trying to bind a user to tables:
home and company
But I get an error
1364 Field 'avatar' doesn't have a default value
laravel 5.3
The code itself

Schema::create('house', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('user_id')->unsigned();
            $table->string('description');
            $table->string('country');
            $table->string('region');
            $table->string('street');
            $table->string('nomer_doma');
            $table->timestamps();
            $table->foreign('user_id')->references('id')->on('users');
        });

What exactly in the message " Field 'avatar' doesn't have a default value " do you not understand?
The avatar field (from some other table, most likely users ) must either be nullable or have a default value, or you must substitute a value when creating the entry.
