DBT 0.21.0 requires new configuration to override global DBT macros

[mroy-seedbox]

See https://docs.getdbt.com/reference/dbt-jinja-functions/dispatch#overriding-global-macros

dispatch:
  - macro_namespace: dbt
    search_order: ['my_project/my_package', 'dbt']

@mroy-seedbox did you get this to work? I'm struggling with this

[mroy-seedbox]

Yup, all you need is something like this in your dbt_project.yml:

name: my_project

# Allow my macros to override global DBT macros
dispatch:
  - macro_namespace: dbt
    search_order: ['my_project', 'dbt']

[AdrianCio]

This is strange, I did this but it gives me No materialization 'plain' was found for adapter postgres! (searched types 'default' and 'postgres')

[mroy-seedbox]

That is weird indeed! But I've never tested it with Postgres (only with Snowflake)... maybe there's something missing to make it work? 🤔

[mroy-seedbox]

Try with something like this:

# Allow my macros & DDO macros to override global DBT macros
dispatch:
  - macro_namespace: dbt
    search_order: ['my_project', 'dbt_packages/DDO/macros', 'dbt']

[AdrianCio]

Same issue :(

macro-paths: 
  - "macros"
  - dbt_modules/DDO/macros/materializations

# Allow my macros & DDO macros to override global DBT macros
dispatch:
  - macro_namespace: dbt
    search_order: ['my_project', 'dbt_modules/DDO/macros', 'dbt']

[mroy-seedbox]

Try with dbt_packages/ instead of dbt_modules/.

dbt_modules/ was for older versions of DBT.

Same result with this config. It is a good point that I was using the old name, but unfortunately it didn't change the output.
I also ran a quick test where I removed dbt_packages from clean-targets but again, same result as in my previous post.

macro-paths: 
  - "macros"
  - dbt_packages/DDO/macros/materializations

# Allow my macros & DDO macros to override global DBT macros
dispatch:
  - macro_namespace: dbt
    search_order: ['my_project', 'dbt_packages/DDO/macros', 'dbt']

target-path: "target"  # directory which will store compiled SQL files
clean-targets:         # directories to be removed by `dbt clean`
  - "target"
  - "dbt_packages"

[mroy-seedbox]

Have you tried creating a copy of the materialization in your own project?

If that doesn't work, then it must be something specific to do with the DBT Postgres implementation. 😕

[mroy-seedbox]

@AdrianCio: did it work? 😅

[AdrianCio]

Apologies, I was off for a week. Indeed I ended up copying the materialization in my project which works fine.
