I am experimenting with building a web app in Rust using Tera and there is a panic every time on the render() call below. Example of the chunk of code:
async fn login(tera: web::Data<Tera>) -> impl Responder {
let mut data = Context::new();
data.insert("title", "Login");
let rendered = tera.render("login.html", &data).unwrap();
HttpResponse::Ok().body(rendered)
}
Link to my repo to review: https://github.com/ClusterberrySquirrels/oasis/blob/oasis_db/src/main.rs
I get the following panic call:
thread 'actix-rt:worker:0' panicked at 'called `Result::unwrap()` on an `Err` value: Error { kind: TemplateNotFound("login.html"), source: None }', src/main.rs:101:53
Something fixed this panic when I was having the same problem at the beginning of this project on the index.html page. At first I thought it was Tera causing the issue but I didn't find any steps to fix it. Eventually something I did made it behave as intended and everything was fine until now. I would appreciate any advice on how to fix this and avoid it happening in the future.
File structure:
Project Folder\
templates\
login.html
index.html
src\
main.rs
Trouble shooting on my side not necessarily in order:
- Switch toolchain default from stable -> cargo build/run, to nightly -> cargo build/run and back.
- rustup update
- sudo apt update
- sudo apt upgrade
- wsl --set-default-version 2
- cargo clean
- Delete target folder then cargo clean, cargo build, cargo run
- cargo update
Update to question: Minimum reproducible example.
use actix_web::{HttpServer, App, web, HttpResponse, Responder};
use tera::{Tera, Context};
async fn index(tera: web::Data<Tera>) -> impl Responder {
let mut data = Context::new();
let posts = [
Post {
title: String::from("This is the first link"),
link: String::from("https://example.com"),
author: String::from("Nutrition-Tracker"),
},
Post {
title: String::from("This is the second Link"),
link: String::from("https://example.com"),
author: String::from("Other cool app"),
},
];
data.insert("title", "index");
data.insert("posts", &posts);
let rendered = tera.render("index.html", &data).unwrap(); // TemplateNotFound??
HttpResponse::Ok().body(rendered)
}
async fn login(tera: web::Data<Tera>) -> impl Responder {
let mut data = Context::new();
data.insert("title", "Login");
let rendered = tera.render("login.html", &data).unwrap(); // TemplateNotFound??
HttpResponse::Ok().body(rendered)
}
#[actix_web::main]
async fn main() -> std::io::Result<()> {
HttpServer::new(|| {
let tera = Tera::new("templates/**/*").unwrap();
App::new()
.data(tera)
.route("/", web::get().to(index))
.route("/login", web::get().to(login))
})
.bind("127.0.0.1:8000")?
.run()
.await
}
