What's new

• Introduce maybe_find methods & functions for optional single model queries (https://github.com/nodecosmos/charybdis/commit/ac1e013c6d66dbfc673d2d99d5923a667ca1fb8a)
  • maybe_find_by_primary_key
  • maybe_find_by_primary_key_value
  • maybe_find_first

let user = User::new();
user.maybe_find_by_primary_key().execute(db_session).await -> Result<Option<Model>, CharybdisError>

What's new

• fix: to_json model serialization

What's new

• local_secondary_indexes are now defined as list of fields. Partition key is derived from partition_keys part of macro declaration and each element in array will result with new local index so now we just do:

  #[charybdis_model(
      table_name = menus,
      partition_keys = [location],
      clustering_keys = [name, price, dish_type],
      global_secondary_indexes = [],
      local_secondary_indexes = [dish_type]
  )]
  

What's new

• updated docs
• fix: ignore non .rs files in charybdis-migrate

Features

• Add configurable queries with method chaining by in https://github.com/nodecosmos/charybdis/pull/7
• Make batch configurable with method chaining in https://github.com/nodecosmos/charybdis/pull/7
• Add increment/decrement counter methods in https://github.com/nodecosmos/charybdis/pull/7

What's new (Breaking changes)

1. All Operations: find, insert, update, delete now return CharybdisQuery that can be configured before execution.

   let user = user.find_by_primary_key().consistency(Consistency::One).execute(session);
   

2. Macro generated operations also return CharybdisQuery so instead of:

   User::find_by_id(session, id).await?;
   

   we have configurable:

   User::find_by_id(id).consistency(Consistency::All).execute(db_sesison).await?;
   

3. Callbacks: We now have only single Callbacks trait that is used for all operation that can accept extension.
   In case extension is not needed, we can use blank ().

4. Batch Operations: Batch is now coupled with Model and it's created by calling Model::batch() method. It
   can also be configured before execution.

   let batch = User::batch().consistency(Consistency::One).chunked_insert(&session, users, 100).await?;
   

5. Counter: Now we have macro-generated increment_<field_name> and decrement_<field_name> model methods to update counter fields.
