mango-orm

ORM-like API MongoDB for Rust

To simulate fields of type ForeignKey and ManyToMany, a simplified alternative (Dynamic Widgets) is used. For examples of how to add fields to the Model, see tests. For maximum convenience use mango-panel.

Requirements

• mongodb
• serde
• chrono
• image
• lazy_static
• rand
• regex
• rust-argon2
• serde_json
• validator
• metamorphose
