D3_FORMATS PROBLEM about superset HOT 5 OPEN

To change the number format to European in Apache Superset, modifying the superset_config.py file alone might not be sufficient. Instead, you should update the D3FormatConfig.ts file in the frontend code. Here’s how you can do it:

1. Locate the D3FormatConfig.ts file in the frontend codebase:

   superset-frontend/packages/superset-ui-core/src/number-format/D3FormatConfig.ts
   

2. Update the DEFAULT_D3_FORMAT parameter to use a European format locale definition. Here’s an example:

   import { FormatLocaleDefinition } from 'd3-format';
   
   export const DEFAULT_D3_FORMAT: FormatLocaleDefinition = {
     decimal: ',',
     thousands: '.',
     grouping: [3],
     currency: ['€', ''],
   };

This change will ensure that the number format is applied globally across your Superset instance ^[1].

Additionally, ensure that there are no overriding configurations in other files such as superset_config_docker.py or any other local configuration files that might affect the D3_FORMATS settings ^[2][3][4].

To ensure that your changes to D3FormatConfig.ts and config.py are applied correctly, follow these steps:

1. Recompile the Frontend Code:
   After modifying D3FormatConfig.ts, you need to recompile the frontend assets. You can do this using Docker commands provided in the Superset repository:

   docker-compose up

   Alternatively, you can use the js_build.sh script located in the superset-frontend directory to rebuild the frontend assets:

   cd superset-frontend
   ./js_build.sh

2. Ensure Configuration is Loaded:
   Make sure that your custom superset_config.py is recognized by setting the SUPERSET_CONFIG_PATH environment variable to the full path of your superset_config.py file. For example:

   export SUPERSET_CONFIG_PATH=/app/superset_config.py

   If you are using Docker, you can add your overrides as shown below:

   COPY --chown=superset superset_config.py /app/
   ENV SUPERSET_CONFIG_PATH /app/superset_config.py

3. Restart Services in Correct Order:
   Restart the services in the following order to ensure that the configuration changes are applied correctly:

   docker-compose restart redis db superset superset-init superset-worker superset-worker-beat

4. Clear Cache:
   Clear the cache to ensure that the new configuration is applied. You can do this by adding the following lines to your superset_config.py:

   from superset.utils.cache_manager import cache_manager
   
   cache_manager.cache.clear()
   cache_manager.data_cache.clear()
   cache_manager.thumbnail_cache.clear()
   cache_manager.filter_state_cache.clear()
   cache_manager.explore_form_data_cache.clear()

   Alternatively, you can clear the cache manually using the following methods:

   cache_manager.cache.clear()
   cache_manager.data_cache.clear()
   cache_manager.thumbnail_cache.clear()
   cache_manager.filter_state_cache.clear()
   cache_manager.explore_form_data_cache.clear()

By following these steps, you should be able to apply the changes to the number format configuration successfully ^[1][2][3][4].

D3_FORMATS isn't a thing, as far as I know. There is D3_FORMAT in config.py, but that takes the parameters for a single format, not an array or object of various formats like you seem to be using.

Hi,
I've modified the D3FormatConfig.ts file, as per follow:
import { FormatLocaleDefinition } from 'd3-format';

export const DEFAULT_D3_FORMAT: FormatLocaleDefinition = {
decimal: ',',
thousands: '.',
grouping: [3],
currency: ['€', ''],
};

I've modified also the config.py:

class D3Format(TypedDict, total=False):
decimal: str
thousands: str
grouping: list[int]
currency: list[str]

#D3_FORMAT: D3Format = {}

D3_FORMAT: D3Format = {
"decimal": ",",
"thousands": ".",
"grouping": [3],
"currency": ["€", ""]
}

no changes into: superset_config.py

After those activities I've restarted the docker, but everything is the same, no changes.

Where I'm wrong?
