It will then be accessible via a dynamic property by the same name as the relation. Eloquent will automatically load the relationship for you, and is even smart enough to know whether to call the get (for one-to-many relationships) or first (for one-to-one relationships) method. By convention, Eloquent will take the snake case name of the owning model and suffix it with id.So, for this example, Eloquent will assume the foreign key on the Comment model is postid. So the orderBy method should use these aliases instead. For example, createdat, updatedat in pivot table have got pivotcreatedat, pivotupdatedat aliases. Since, like Eloquent models themselves, relationships also serve as powerful query builders, defining relationships as methods provides powerful method chaining and querying capabilities. Eloquent allows you to access your relations via dynamic properties. Remember, Eloquent will automatically determine the proper foreign key column on the Comment model. If you print out the SQL query of belongsToMany relationship, you will find that the column names of pivot tables are using the pivot prefix as a new alias. Eloquent makes managing and working with these relationships easy, and supports several different types of relationships:Įloquent relationships are defined as methods on your Eloquent model classes. For example, a blog post may have many comments, or an order could be related to the user who placed it. The relevant tables are set up like so: conversations messages messageuser conversationuser - id id messageid conversationid. The new factory class will be placed in your database/factories directory. Dynamic Propertiesĭatabase tables are often related to one another. I am creating a basic messaging system and need to query the data on a pivot table. 1 In other words, I want to check if the user has completed the course or not through the pivot table value isComplete as shown in the example below.
