Multireference fields are a valuable tool when it comes to creating relationships between different content collections in a database. They represent a one-to-many relationship, where one row in one content collection can be related to multiple rows in another content collection. In this article, we will provide a technical explanation of what multireference fields are and how they work, as well as an example to help demonstrate their usage.
To begin, imagine a website that lists different sandwiches and their ingredients. On this website, users can also create their own sandwiches by giving them a name and selecting ingredients from a list. This is an example of the kind of relationship that can be represented using multireference fields. On one side, we have the sandwiches collection, which has a title and a list of ingredients. On the other side, we have the ingredients collection, which has one row for each ingredient.
When defining the properties of the multireference field, we would name the field and set the field type as multireference. Then, a drop-down menu will appear where we can choose which other content collection we are referencing with this field. In this case, it would be the ingredients collection. By doing this, we have tied these two collections together, allowing our sandwich collection to contain multiple ingredients. This is a useful way to represent relationships in a database, as it allows for more efficient querying and insertion of data.
It's worth noting that there are other things that can be done with multireference fields, but once you understand the basics, the rest will come naturally. By the end of this article, you should have a good understanding of what multireference fields are and how to use them in your code, including how to query for them and how to insert them. With this knowledge, you'll be able to create complex and efficient relationships between different content collections in your database.
