# diesel
Basic integration of [Diesel](https://diesel.rs/) using SQLite for Actix Web.
## Usage
### Install SQLite
```sh
# on OpenSUSE
sudo zypper install sqlite3-devel libsqlite3-0 sqlite3
# on Ubuntu
sudo apt-get install libsqlite3-dev sqlite3
# on Fedora
sudo dnf install libsqlite3x-devel sqlite3x
# on macOS (using homebrew)
brew install sqlite3
```
### Initialize SQLite Database
```sh
cd examples/diesel
cargo install diesel_cli --no-default-features --features sqlite
echo "DATABASE_URL=test.db" > .env
diesel migration run
```
There will now be a database file at `./test.db`.
### Running Server
```sh
cd examples/diesel
cargo run (or ``cargo watch -x run``)
# Started http server: 127.0.0.1:8080
```
### Available Routes
#### `POST /user`
Inserts a new user into the SQLite DB.
Provide a JSON payload with a name. Eg:
```json
{ "name": "bill" }
```
On success, a response like the following is returned:
```json
{
"id": "9e46baba-a001-4bb3-b4cf-4b3e5bab5e97",
"name": "bill"
}
```
Client Examples
Using [HTTPie](https://httpie.org/):
```sh
http POST localhost:8080/user name=bill
```
Using cURL:
```sh
curl -S -X POST --header "Content-Type: application/json" --data '{"name":"bill"}' http://localhost:8080/user
```
#### `GET /user/{user_uid}`
Gets a user from the DB using its UID (returned from the insert request or taken from the DB directly). Returns a 404 when no user exists with that UID.
Client Examples
Using [HTTPie](https://httpie.org/):
```sh
http localhost:8080/user/9e46baba-a001-4bb3-b4cf-4b3e5bab5e97
```
Using cURL:
```sh
curl -S http://localhost:8080/user/9e46baba-a001-4bb3-b4cf-4b3e5bab5e97
```
### Explore The SQLite DB
```sh
sqlite3 test.db
```
```
sqlite> .tables
sqlite> SELECT * FROM users;
```
