Pagination First, Last, Next, and Previous Buttons
In this lesson, we'll take a look at how to add pagination links to the next and previous pagination pages. Then, we'll follow the same process to add links to the first and last pagination pages.
How To Paginate Filtered Query Results
In this lesson, we'll learn about AdonisJS Model Query Builder pagination and walk through an example of how we can easily paginate the results of our filtered movies.
Joining SQL Tables To Order By A Related Column
In this lesson, we'll learn how to join a related table into our query and use that table to apply a sort via the relationship. We'll then see how we can conditionally apply this join only when it's needed for the selected order by.
How To Apply A Dynamic Sort Filter To Your Query
In this lesson, we'll learn how we can add a user-selected sort option to our filters. Then, we'll apply the selected filter to our movie query
Filtering Our List by Movie Status
In this lesson, we'll alter our form input component to allow selects. Then, we'll learn how to add a select-based filter to our movie list page so that we can see only movies containing a specific movie status.
Filtering A Query By Pattern Likeness
In this lesson, we'll learn how to add a pattern filter to our movies.index page that will allow us to filter our movies list by title using a case-insensitive pattern search.
Remembering A User's Authenticated Session
In this lesson, we'll learn how we can use AdonisJS' Remember Me Tokens feature to allow a user to specify they'd like their authentication state to be remembered for a long time across sessions.
Logging In An Existing User
In this lesson, we'll learn how we can login an existing user using just their email and password. We'll discuss how the AuthFinder mixin protects us from timing attacks, and how we can use it to verify the accuracy of a user's password.
AdonisJS 6 Session Authentication in 15 Minutes
In this lesson, we'll learn how to add authentication to a new AdonisJS 6 application using the session guard. In these 15 minutes, you'll learn how to register a user, logout a user, verify a user's credentials and log them in, and more.
How To Query, Sort, and Filter by Pivot Table Data
In this lesson, we'll learn how we can query pivot table data. We'll then learn how we can also sort and filter our results by those pivot table columns as well.
How To Create Factory Relationships from a Pool of Data
In this lesson, we'll learn how we can refactor our fake data seeder to allow us to assign cast members and crew members to our movies via our many-to-many relationships from a single pool of cineast records.
A Deep Dive Into Relationship CRUD with Models
In this lesson, we'll take a deep look at how we can perform CRUD operations with one-to-one, one-to-many, many-to-one, and many-to-many relationships using our Lucid Models.
Many-To-Many Model Factory Relationships
In this lesson, we'll learn how we can define and use many-to-many relationships with Model Factories, including how we can define pivot table data when creating our fake records.
Defining Many-To-Many Relationships and Pivot Columns
In this lesson, we'll learn how you can define many-to-many relationships within your Lucid ORM Models. We'll also discuss the relationship options, and how you can automatically include pivot table data with all queries.
Using Eager and Lazy Loading to Load A Movie's Writer and Director
In this lesson, we'll learn how we can use eager loading to preload our writer and director onto our movie's details. We'll then, learn how we can load our writer and director onto our movie's details using lazy loading.
