Green Barrel

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 actix-green-panel.

crates.io

Attention

MongoDB Rust Driver version 1.2.5 is used.

Actix-green-panel is the recommended part of the entire ecosystem ( green-barrel, metamorphose, actix-green-pane ). For those who use actix-green-panel - Follow our updates.

Requirements

Model parameters

( all parameters are optional )

Match field types and widget types

Field attributes

( all attributes are optional )

Install mongodb (if not installed)

```shell

Ubuntu, Mint:

$ sudo apt install mongodb

OR

Ubuntu 20.04, Mint 20.x:

$ sudo apt update $ sudo apt install dirmngr gnupg apt-transport-https ca-certificates $ wget -qO - https://www.mongodb.org/static/pgp/server-4.4.asc | sudo apt-key add - $ sudo add-apt-repository 'deb [arch=amd64] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse' $ sudo apt update $ sudo apt install mongodb-org $ sudo systemctl enable --now mongod

For check

$ mongod --version $ mongo --eval 'db.runCommand({ connectionStatus: 1 })' $ reboot #

Configuration file:

$ sudo nano /etc/mongod.conf #

Systemd:

$ sudo systemctl status mongod $ sudo systemctl start mongod $ sudo systemctl stop mongod $ sudo systemctl restart mongod $ sudo systemctl enable mongod $ sudo systemctl disable mongod #

Uninstall:

$ sudo systemctl stop mongod $ sudo systemctl disable mongod $ sudo apt --purge remove mongodb* # OR (for mongodb-org) - $ sudo apt --purge remove mongodb-org** $ sudo rm -r /var/log/mongodb $ sudo rm -r /var/lib/mongodb $ sudo rm -f /etc/mongod.conf $ sudo apt-add-repository --remove 'deb [arch=amd64] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/4.4 multiverse' # for mongodb-org $ sudo apt update ```
