Working with forms
The next example shows the use of ArangoDB with Symfony’s form component.
This is how our form will look like. The topics are represented as a text field and the user is required to separate them by commas. This delivers questionable user experience, but leads to an interesting question: how can we transform our topics array from our movie document to a text field? And: we’ll need it at least two times, both for creating and editing movies.
