Relationships fields: belongsTo/belongsToMany

QuickAdminPanel supports two types of relationships between CRUDs:

• One-to-Many: belongsTo() + hasMany()

• Many-to-Many: belongsToMany().

To create a relationship, you just need to choose field type belongsTo or belongsToMany.

You don't need to manually create separate field or pivot table, they will be created automatically:

• In case of belongsTo, QuickAdminPanel will automatically create DB column xxxxxx_id with a foreign key to the parent table.

• In case of belongsToMany, QuickAdminPanel will automatically create a pivot table, you don't need to create that table manually.

Here are examples of filled-in forms for belongsTo and belongsToMany:

This will automatically generate column vehicles.owner_id with foreign key to users table

This will automatically generate role_user pivot table

Showing Related Children Records on Parent's Page

One more feature: you can enable the children's records to be shown in a show() method page of a parent CRUD.

If you tick that checkbox, then on the View page of the Parent's CRUD you will see a table of children's record:

You click "View" on parent's record

And it will show children records at the bottom
