In this video Emmanuel Henri demonstrates how to make a list of items within a field so you can list multiple items inside a field, like a list.
- [Instructor] In many cases you will need to have…inside of a field, multiple values,…for example, a list of episodes a character…is featured in for a television show.…This is where you can create a type…and use the array characters to signify…a list of items inside the field.…In our case, we would like to implement a way…to list contacts for a friend.…Let's get to it.…So again, open the schema,…and inside of our type Friend here,…let's create a new field called contacts, like so.…
And then this contacts takes a list of contacts,…so you are making an array of a type Contact.…So we need to create that type.…So let's go ahead and create the type Contact,…which will basically have a first name,…which is a String, and then a last name,…which is also a String.…And let's make sure we also create an input,…so we can enter these contacts.…
So we need to create a contact input.…So just below the input here,…let's create a new one, ContactInput,…and again, same thing here.…So let's copy from line 16 to 17,…and let's paste these right there, very simple.…
