jasperav / catalytic Goto Github PK

Hi,

First, thanks for your amazing crate. Although I really enjoy it, there's some notable difficulities while using it, mostly with the build.rs codegen.

My proposal for this problem is creating a macros that take similar data like the build.rs (query, transformer,...) and user would just need to derive that one trait. This idea is somewhat similar to sea-orm's DeriveEntityModel.

This can be done if the following issues are closed:

• scylladb/scylla-rust-driver#261
• scylladb/scylla-rust-driver#297
• scylladb/scylla-rust-driver#308
• scylladb/scylla-rust-driver#309
• scylladb/scylla-rust-driver#332

When above issues are closed:

1. Check that https://github.com/Jasperav/scylla-rust-driver is the same as the original driver
2. Remove https://github.com/Jasperav/scylla-rust-driver
3. Update to the crates scylla rust driver in this crate
4. Push to crates
5. Add a reference to this crate in the scylla rust driver repo

SCYLLA-UDT
I'm creating the udt types on build and specify the struct

UDT = Team, Teams and League
~build.rs


src/types_helper/betwise.rs

Do I need to use the text type on creation of table for columns that use UDT?

Hi,

It looks dotenv crate is no longer maintained which cargo audit complaints about.
Hopefully there is an up to date fork dotenvy.

Is it possible to replace it with the maintained one?

People can't get answer to their questions(dotenv-rs/dotenv#74, dotenv-rs/dotenv#87) about future of this crate.

And, thanks for your valuable effort.

Howdy!

With catalytic_table_to_struct, is it possible to rename column names? I'm messing around with a very large database with various type columns.

How can I rename them to, say, r#type?

Hello, thank you for this great crate.

My issue is suddenly, I can't compile this crate, I get this error:

failed to resolve: could not find LegacySerializedValues in _macro_internal
--> ../.cargo/registry/src/index.crates.io-6f17d22bba15001f/catalytic-0.1.20/src/table_metadata.rs:34:17

34 | #[derive(Debug, scylla::ValueList, scylla::FromRow)]
| ^^^^^^^^^^^^^^^^^
| |
| could not find LegacySerializedValues in _macro_internal
| help: a struct with a similar name exists: SerializedValues
|
= note: this error originates in the derive macro scylla::ValueList (in Nightly builds, run with -Z macro-backtrace for more info)

Problem might be related to scylla_macros crate. I could compile until yesterday. I compared Cargo.lock files and only difference was scylla_macros crate version is now 0.2.2, which was 0.2.1 until yesterday. 0.2.2 version came yesterday.

When scylladb/scylla-rust-driver#385 is fixed

The ORM does not support TIMESTAMP and TIMEOUTs for inserts yet: https://docs.scylladb.com/getting-started/dml/#insert-statement.

This can be implemented by following these steps:

1. Add the new method name in query_ident.rs. The query ident mod can be used by other users to interact with always up to date methods, so they never have to type the method names themselves and run into run time errors
2. Add the new insert method somewhere in write_struct.rs, after the insert method (see line 177).
3. Add a test in lib.rs. I want each new change to be tested.

To see the changes of the generated code easily:

1. Change a line somewhere in build.rs. (there is no cargo:rerun-if-changed). This should trigger re-generation of the structs. The structs are in version control, so it should be easy to see what has been changed.
2. Run the test in lib.rs.

I am using ScyllaDB with Leptos and I would love to use Catalytic. There doesn't seem to be much activity here. Is it a good idea to start using the project?

That way it can take &self instead of self

Because the output is different than the local compiler although they are using the same version. Check with rust 1.56 if this is still different

At work, we have a table api_keys_by_id, with a materialized view api_keys_by_orgId. However, when catalytic_table_to_struct creates the MV, it doesn't do much. Here's the generated code, shortened a little:

// Generated file
pub const SELECT_ALL_QUERY: &str = "select  from api_keys_by_orgId";
pub const SELECT_ALL_COUNT_QUERY: &str = "select count(*) from api_keys_by_orgId";
pub const SELECT_UNIQUE_QUERY: &str = "select  from api_keys_by_orgId where ";
#[derive(
    scylla :: FromRow, scylla :: ValueList, catalytic_macro :: Mirror, Debug, Clone, PartialEq,
)]
pub struct ApiKeysByOrgId {}
impl ApiKeysByOrgId {
    pub fn primary_key(&self) -> PrimaryKeyRef {
        PrimaryKeyRef {}
    }
    pub fn primary_key_owned(&self) -> PrimaryKey {
        self.primary_key().into_owned()
    }
    pub fn into_primary_key_owned(self) -> PrimaryKey {
        PrimaryKey {}
    }
}

This is the get_columns function:

select
    column_name,
    kind,
    position,
    type as data_type
from system_schema.columns
where keyspace_name = 'spore'
and table_name = 'api_keys_by_orgId';

and it's response:

Because else a mismatch can easily occur in Scylla versions

Hey! I'm Daniel, Developer Advocate at ScyllaDB and I truly liked your project! It's my first time trying Rust and the way that Catalytic works is fascinating!

I'm wondering if there's any way of me contributing to docs improvements on this project. I mean, it's a great tool but there's not so much information on how to use it and for me from a few hours ago it would be real important :p

In any case I'm here to offer some help to struct some cool documentation for this project! What do you think?

Cheers!
