So preferably like the above method with eloquent, where I output $score->ratingtext, $score->ratingradio, $score-id, and whatever I want. But I don't only want to display the comment, I also want to be able to display all Information regarding this Element. $comments = array_reverse($comments, true) Īnd then looping through the $comments.
Reverse the array, to have the latest element first displayed $comments = array_slice($comments, -20, 20, true) $commenttype = $scores->lists('ratingradio') $comments = $scores->lists('ratingtext') I attempted solving it like this in my Controller: $scores = Score::where('unit_id', $id)->where('created_at', '>', Carbon::now()->subDays(3))->get() Normally I would go about solving it like this: as I don't only want the order to be reversed, but I also want the array to be sliced, so that it just outputs the last 20 Elements of the array. Now, let's imagine we want to retrieve ActivityFeed instances and eager load the parentable parent models for each ActivityFeed instance.I have a Score-Table with different ratings, strings and radio-buttons. I know we can use ->toSql () in laravel but sometimes I need it directly in the database manager to test it, whereas eloquent can't be executed in Database Manager of course because it is one of Laravel's features.

Additionally, let's assume that Photo models "have many" Tag models and Post models "have many" Comment models. I hope it's like a web generator or script or something where we just paste the eloquent and the result is an sql query. We will assume the ActivityFeed model defines a "morph to" relationship named parentable that allows us to retrieve the parent Photo or Post model for a given ActivityFeed instance. In this example, let's assume that Photo and Post models may create ActivityFeed models. If you would like to eager load a "morph to" relationship, as well as related model counts for the various entities that may be returned by that relationship, you may utilize the with method in combination with the morphTo relationship's morphWithCount method. We can summarize the relationship's table structure like so:Ĭounting Related Models On Morph To Relationships In order to provide support for roles being assigned to multiple users, the role_user table is needed. This would mean that a role could only belong to a single user. Remember, since a role can belong to many users, we cannot simply place a user_id column on the roles table. This table is used as an intermediate table linking the users and roles. The role_user table is derived from the alphabetical order of the related model names and contains user_id and role_id columns. To define this relationship, three database tables are needed: users, roles, and role_user. So, a user has many roles and a role has many users.

For example, a user may be assigned the role of "Author" and "Editor" however, those roles may also be assigned to other users as well. Next in series: How To Order Query Results in Laravel Eloquent -> Tutorial Series: A Practical Introduction to Laravel Eloquent ORM Eloquent is an object relational mapper (ORM) that is included by default within the Laravel framework. An example of a many-to-many relationship is a user that has many roles and those roles are also shared by other users in the application. Many-to-many relations are slightly more complicated than hasOne and hasMany relationships. Return $this -> throughEnvironments () -> hasDeployments () Eloquent makes managing and working with these relationships easy, and supports a variety of common relationships: For example, a blog post may have many comments or an order could be related to the user who placed it.
