The second one is used to change data directly from your application.The remaining functions in this module, such as validations, constraints, association handling, are about manipulating changesets.

When using any of those APIs, you may run into situations where Ecto sees data is being replaced.The difference between them is that most validations can be executed without a need to interact with the database and, therefore, are always executed before attempting to insert or update the entry in the database.Some validations may happen against the database but they are inherently unsafe. On the other hand, constraints rely on the database and are always safe.If you need deletion, it is often preferred to add a separate boolean virtual field to the changeset function that will allow you to manually mark it for deletion, as in the example below: This means that when working with changesets that are not meant to be persisted to the database, such as schemaless changesets, you may need to explicitly set the action to one specific value.Frameworks such as Phoenix use the action value to define how HTML forms should act.
