[dependabot-preview]

Bumps ecto from 3.2.5 to 3.4.2.

Changelog

Sourced from ecto's changelog.

v3.4.2 (2020-04-10)

Enhancements

• [Ecto.Changeset] Support multiple fields in unique_constraint/3

v3.4.1 (2020-04-08)

Enhancements

• [Ecto] Add Ecto.embedded_load/3 and Ecto.embedded_dump/2
• [Ecto.Query] Improve error message on invalid JSON expressions
• [Ecto.Repo] Emit [:ecto, :repo, :init] telemetry event upon Repo init

Bug fixes

• [Ecto.Query] Do not support JSON selectors on type/2

Deprecations

• [Ecto.Repo] Deprecate conflict_target: {:constraint, _}. It is a discouraged approach and {:unsafe_fragment, _} is still available if someone definitely needs it

v3.4.0 (2020-03-24)

Enhancements

• [Ecto.Query] Allow dynamic queries in CTE and improve error message
• [Ecto.Query] Add Ecto.Query.API.json_extract_path/2 and JSON path support to query syntax. For example, posts.metadata["tags"][0]["name"] will return the name of the first tag stored in the :map metadata field
• [Ecto.Repo] Add new default_options/1 callback to repository
• [Ecto.Repo] Support passing :telemetry_options to repository operations

Bug fixes

• [Ecto.Changeset] Properly add validation annotation to validate_acceptance
• [Ecto.Query] Raise if there is loaded non-empty association data without related key when preloading. This typically means not all fields have been loaded in a query
• [Ecto.Schema] Show meaningful error in case schema is invoked twice in an Ecto.Schema

v3.3.4 (2020-02-27)

Bug fixes

• [mix ecto] Do not rely on map ordering when parsing repos
• [mix ecto.gen.repo] Improve error message when a repo is not given

v3.3.3 (2020-02-14)

Enhancements

• [Ecto.Query] Support fragments in lock
• [Ecto.Query] Handle nil in select_merge with similar semantics to SQL databases (i.e. it simply returns nil itself)
