In this tutorial, you have learned how to define one to many relationship and using this relationship how to perform crud operation with an eloquent model from database tables.
#Laravel eloquent delete related models code
To delete all posts for a particular author use below code example. Firstly we get the parent object which is brand and then use the post() method to delete all post. $author = Author::find(1) ĭeleting one to many relationship is the same as we have created them. You can chain the methods on your retrieving query. You might want to filter the related records and want them to sort when retrieving. You can also use the saveMany() method instead of save() to associate multiple records. To create a relationship between two models or associating them, we can first create a child object and then save it using the parent object. Similarly, you can retrieve the inverse related model. In this example, you can get all posts of a particular author: $posts = Author::find(10)->post()->get() Once you have defined the relationship on models, you can retrieve data from the DB table using the eloquent model.
If you don't particularly like that approach, you will need to iterate your collection of organization products and call delete() on them individually.Using this, Here we need to get the author details by using posts, for each post there a single author, within the Post model includes belongsTo relation. now this will only destroy ids associated with the org $orgIds = array_intersect($org->products()->lists('id'), $ids) intersect the product ids for the org with those passed in As you mention in a comment, it won't restrict the deletion to only those products in the organization, so you would need to filter out those ids before passing the list into the destroy() method. It will load a new model for each id, and then call delete() on it. In this case, you can use the destroy method on the model that takes a list of ids. If you have event listeners for the deleting/ deleted model events, you will need to make sure the deletion happens in a way that each model is loaded and then deleted. The issue is that you're calling delete() on a Collection, which does not have that method. Is? From what I see, both find and get are returning Collections I guess, I'm also trying to understand what the difference between: $org->products()->find($ids)->delete()Īnd $org->products()->whereIn('id', $ids)->get()->delete() The stroy code works fine if I pass it a single id The model Product has several belongsTo relationships with other models.Ģ. I have verified that find() is returning a collection of products matching the specified ids.ġ. This gives me the following error: BadMethodCallException in Macroable.php line 81:Īt Collection->_call('delete', array()) in ProductsController.php line 251Īt Collection->delete() in ProductsController.php line 251Īt ProductsController->destroy('62100dd6-7ecf-4870-aa79-4b132e60c904,c4b369f1-d1ef-4aa2-b4df-b9bc300a4ff5') Automatically deleting related rows in Laravel (Eloquent ORM) Ask Question Asked 10 years, 6 months ago Modified 2 months ago Viewed 378k times 214 When I delete a row using this syntax: user->delete () Is there a way to attach a callback of sorts, so that it would e.g. On the other end, my controller action looks like so: public function destroy($id) I call the stroy route using comma separated list of ids ( id is of postgres type uuid), like so: Request URL: I have the id's of all the records I wish to delete. I want to be able to delete multiple records from the database. Now this, from what I can see, should have been simple.
