Update: According to this issue async does not work with Diesel, so, the method to_async from web::get might not work as expected, it will work but...

This is a really awesome write-up, thank you!

Have you attempted to port an application from actix_web 0.7 to 1.0 yet? If so, how did it go? There are some significant API changes so I haven't tried yet.

Werner Echezuría • May 14 '19

Hi, thanks.

In the meantime I'm learning about the migration from 0.7 to 1.0 and I'm trying to document everything I can. Something I've realized it's that is easier to create handlers and assigning it to a Server.

you don't have models.rs? in ur project so it confuse for newcomer :) prnt.sc/p0bfqb

Werner Echezuría • Sep 1 '19

Oops!, thanks for pointing this out, fixed now.

Saroar Khandoker • Sep 1 '19

thanks also like to know so you know about the swift back end? I am a little bit confuse is Rust is ready for the production type of API app for a mobile app? i have my own API written in swift that's working good but i am also interested in RUST so i start to reading you post :)

Werner Echezuría • Sep 1 '19

I think as an API backend Rust is ready for production, might need to polish some areas but you could have your app deployed with confident. for example: figma.com/blog/rust-in-production-...

do you know swift back end like vapor ? if yes what you think about swift back end?
thanks

Werner Echezuría • Sep 1 '19

To be honest, I don't know swift, so I can't make an informed opinion about it.

Saroar Khandoker • Sep 1 '19

ok no worry thanks for reply also check this prnt.sc/p0et3l image you don't have still extern crate futures; and you add it so its give us error too

  --> src/main.rs:16:1
   |
16 | extern crate futures;
   | ^^^^^^^^^^^^^^^^^^^^^ can't find crate

but and trying to understand why it not showing :( my products list already debugging more then 2 hours :(

Saroar Khandoker • Sep 1 '19

here is my code please check me if you will have
bitbucket.org/Alifdev/ruststore

Hi, sorry for the late response, I was on vacations. Try to follow these tips and tell me if it works.

git checkout v1.1.
diesel setup.
cargo run.
curl http://127.0.0.1:8088/products -H "Content-Type: application/json" -d '{"name": "socks", "stock": 7, "price": 2}
curl http://localhost:8088/products

Tell me if it works.

Saroar Khandoker • Sep 7 '19

yes it is working thanks :)

Hi, your tutorial is awesome!

But I find a little issue of diesel that the line

use crate::schema::products::dsl::*;

in ProductList implementation cannot be placed in the top which will cause an unmatched type error of id in find method of Product implementation.

This issue caused by a duplicated id from crate::schema::products::dsl.

Werner Echezuría • Aug 14 '19

Hi, did you take a look at the last version, sometimes I fix these issues but I forgot to mention them, github.com/practical-rust-web-deve...

Ryan Li • Aug 16 '19

Thanks for your reply. Your source code can works well.

It is my bad to take the line above to the top of the module. 😄

Thats a neat tutorial! Would like to see how we can use tokio in conjunction with actix. For eg. making multiple async calls(futures) to db, wait for all the futures, aggregate the resultset and respond to the request. I couldn't find any examples like that anywhere

Shawn McElroy • Jul 11 '19

I am still going through these and am new to Rust. But being used to frameworks like flask in python, is it easy or possible to abstract out the model methods to not have the boilerplate for the db connection?

some frameworks make it so you can do request.db or maybe move it to a parent model or something? that way the model methods are a lot cleaner?

Werner Echezuría • Jul 11 '19

Well, I think it's possible, passing the db connection through a Trait, and then implements the trait for every model. Seems like a fun thing to do, maybe in a future post I'll try to implement it.

Shawn McElroy • Jul 12 '19

that would be great.

Saroar Khandoker • Sep 12 '19

impl ProductList {
    pub fn list() -> Self {
        ProductList(result)
    }
}```

 from 

to


```Rust
impl Product {
    pub fn list() -> Self {
        ProductList(result)
    }
}```



then use `Product::list()` look better and don't repeat list two times
