Errors on `get_result`, `execute`, `first::`, `diesel::AsChangeset`

[SamuelMarks]

Running:

dsync -i 'src/schema.rs' -o 'src/generated_models' -c 'diesel::pg::Pg' --single-model-file

Which produces a bunch of files with a bunch of errors.

For example, this one (which seems to be referenced in #94):

Other errors also but this should give you the gist. I'm sure I'm doing something wrong, my types are super simple so not sure what that is. My schema.rs:

4 | use crate::diesel::*;
  |            ^^^^^^ could not find `diesel` in the crate root

dsync currently expect you to re-export diesel on the crate level, see for example this test

1 error[E0277]: the trait bound NaiveDateTime: diesel::Expression is not satisfied

do you have the chrono feature enabled in diesel? see this example cargo toml

---

as for the other errors, do they still appear when fixing the above ones?

also please provide what version you are using of dsync (or git commit if using self-compiled)? in addition known the used diesel version would also be good.
