I wish this help you I have 2 models I need to save to. In this instance, I do not need cakePHP to saveAll(), but want to save the content manually. , You can use cakephp's saveAssociated() method:
code :
$this->Model1->saveAssociated($this->request->data);

Save multiple child models in Yii

Hope this helps The correct syntax to render what an array of models (doesn't matter if they are child models or not) requires the instantiation of the model in question. So you would have to do something like this in your view:
code :
$child = new ChildModel();
$form->textFieldRow($child,'[]PROPERTY',$dateAtts);
$event->appointments = array(new Appointment);
<?php foreach($model->appointments as $id => $item) : ?>
    <div class="appointment">
        <?php echo $form->textFieldRow($item,'[$id]day',$htmlAtts); ?>
    </div>
<?php endforeach; ?>
$form->textFieldRow(
            $item,
            '[$id]day', 
            array('name' => "Event[appointments][$id][day]")
       );

Save multiple models in loopback

like below fixes the issue You can create RemoteMethods in a Model, which can define parameters, so in your example you could create something like this in your Post model:
code :
// remote method, defined below
Post.SaveFull = function(title, 
        description,
        tags,
        imageUrl,
        cb) {

    var models = Post.app.Models; // provides access to your other models, like 'Tags'

    Post.create({"title": title, "description": description}, function(createdPost) {
         foreach(tag in tags) {
             // do something with models.Tags

         }
         // do something with the image

         // callback at the end
         cb(null, {}); // whatever you want to return
    })

}

Post.remoteMethod(
    'SaveFull', 
    {
      accepts: [
          {arg: 'title', type: 'string'},
          {arg: 'description', type: 'string'},
          {arg: 'tags', type: 'object'},
          {arg: 'imageUrl', type: 'string'}
        ],
      returns: {arg: 'Post', type: 'object'}
    }
);

Save multiple models at a time in Yii2

I wish did fix the issue. You should use transactions to ensure both models are saved correctly. Example:
code :
$transaction = Yii::$app->db->beginTransaction();

try  {
    if ($model->save() && $userModel->save()) {
        $transaction->commit();
    } else {
        $transaction->rollBack();
    }
} catch (Exception $e) {
    $transaction->rollBack();
}

How to save scikit-learn MULTIPLE classifier models with python pickle library (or any efficient others)


By : Anirudh Rs
Date : March 29 2020, 07:55 AM
this will help In general, we could use pickle to save ONE classifier model. Is there a way to save MULTIPLE classifier models in one pickle? If yes, how could we save the model and retrieve it later? , You can save multiple objects into the same pickle:
code :
with open("models.pckl", "wb") as f:
    for model in models:
         pickle.dump(model, f)
models = []
with open("models.pckl", "rb") as f:
    while True:
        try:
            models.append(pickle.load(f))
        except EOFError:
            break
