Read from one database and write to another php/laravel - php

Question

I'm learning Laravel and would know howto read data from a db and write it automatically to a second db.
First I read from db1 and it works:
$paciente_q = Pacientes::on('db1')->find($id);
Then I wish to move the data to an identical table on db2 (assigned in the configuration)
Pacientes::create($paciente_q);
The error is that I pass an object and "::create" wants an array. I converted it to an array but didn't work. The only option that I can find is to create an array with the data and then make the ::create. But I think that there should be an easier way. I'm talking about 10 columns.
What could I do if we talk about hundreds of columns?

Answer 1

Your approach didn't work probably because by default mass assignment is prevented for security reasons; you need to manually set the model's fields that are mass assignable in the fillable property of the model (that should be an array) - if you do not care about that security or are sure that you'll never directly mass-assign user input to your models you can make all the fields mass assignable by setting the guarded property of the model to an empty array.
Once that's done, your code is mostly correct, just convert the model to an array and don't forget to select the second database when creating the model, like so :
// the model to insert, converted to an array - get() would also work but first() ensures we get only one record even if the primary key is messed up and there are multiple values with the same ID
$paciente_q = Pacientes::on("db1")->find($id)->first()->toArray();
// create the same model on the second database
Pacientes::on("db2")->create($paciente_q);
Now, if you want to do it occasionally for a few rows then the above approach is suitable, otherwise you may look at bulk insertion, here's an example for copying the entire table from your first database to the second one :
// an array with all the rows
$patients = Pacientes::on("db1")->all()->toArray();
// get the model's table name
$table = with(new Pacientes)->getTable();
// bulk insert all these rows into the second database
DB::connection("db2")->table($table)->insert($patients);
Note that here we're not using Eloquent for inserting them, so we must first get the table's name from an instance of the model; if the table's name on the second database is different from the first then adjust the $table variable accordingly.

The solution was to change the get() to first() because we were searching for one item. I read wrong the first solution from #André... sorry! Should learn to read instead of Laravel!
$paciente_q = Pacientes::on('db1')->where('numerohistoria',$numerohistoria)->first()->toArray();
Pacientes::create($paciente_q);
Now it works!! Thanks to all and specially to #André !
