Add new localized ProductField's

[monsieurtanuki]

Why - Problem description

I've noticed new localized product fields:

• conservation_conditions_fr
• customer_service_fr

cf. https://fr.openfoodfacts.org/produit/3017620425035/nutella-ferrero.com?fields=conservation_conditions_fr,customer_service_fr

We should implement them as localized fields in ProductField and Product.

i would love to work on this issue

Hi @AffanShaikhsurab!
That should be easy - once you've understood how things work in that project for multilanguage fields.
Good luck!

[AffanShaikhsurab]

I added the fields conservation_conditions_fr and customer_service_fr to the product object. However, I think the issue lies in the conservation_conditions field. The code seems to expect it to be of type List<dynamic> (probably because the field name is plural), but the data being returned is a String.

Here’s an example of the value being returned:
"conservation_conditions_fr": "A conserver au sec et à l'abri de la chaleur. Ne pas mettre au réfrigérateur."

The error we’re encountering is:
Error fetching product: TypeError: "A conserver au sec et à l'abri de la chaleur. Ne pas mettre au réfrigérateur..": type 'String' is not a subtype of type 'List<dynamic>?

How should we approach resolving this issue? Should we:

1. Update the API/logic to return a List<String> instead of a single String for conservation_conditions_fr?
2. Change the code logic to handle String instead of List<dynamic> for this specific case?
3. Change ths conservation_conditions to conservation_condition

I am assuming the issues here please help me to solve the issue

I added the fields conservation_conditions_fr and customer_service_fr to the product object.

@AffanShaikhsurab That may be part of the problem: we don't care about specifically French labels, we want multilingual labels.
I should rather have mentioned https://fr.openfoodfacts.org/produit/3017620425035/nutella-ferrero.com?fields=conservation_conditions_languages,customer_service_languages

{
  "code": "3017620425035",
  "product": {
    "conservation_conditions_languages": {
      "fr": "A conserver au sec et à l'abri de la chaleur. Ne pas mettre au réfrigérateur."
    },
    "customer_service_languages": {
      "fr": "FERRERO FRANCE COMMERCIALE - Service Consommateurs, CS 90058 - 76136 MONT SAINT AIGNAN Cedex"
    }
  },
  "status": 1,
  "status_verbose": "product found"
}

Please use for conservation conditions and customer service the same logic as for product name, cf. https://fr.openfoodfacts.org/produit/3017620425035/nutella-ferrero.com?fields=conservation_conditions_languages,customer_service_languages,product_name_languages

{
  "code": "3017620425035",
  "product": {
    "conservation_conditions_languages": {
      "fr": "A conserver au sec et à l'abri de la chaleur. Ne pas mettre au réfrigérateur."
    },
    "customer_service_languages": {
      "fr": "FERRERO FRANCE COMMERCIALE - Service Consommateurs, CS 90058 - 76136 MONT SAINT AIGNAN Cedex"
    },
    "product_name_languages": {
      "de": "Nutella",
      "en": "Nutella",
      "es": "",
      "fr": "Nutella",
      "zh": "费列罗榛子巧克力酱"
    }
  },
  "status": 1,
  "status_verbose": "product found"
}

Ohh Soory now I see the issue I will fix it asap

[AffanShaikhsurab]

i have added the customer_service_languages , conservation_conditions_languages properly but when regenerating the product.g.dart using the dart run build_runner build i am getting error in different files in model directory / . What should i do ?

Cool!

when regenerating the product.g.dart using the dart run build_runner build i am getting error in different files in model directory / .

Strange, I've never seen that.

What should i do ?

As far as the current issue goes, please create a pull request with only the files needed - regardless of whatever failed generating unrelated files.
Unless you have a problem with product.g.dart too.

[AffanShaikhsurab]

After pulling the repository from GitHub, I did not delete any folder named .dart_tool/build.

However, I am encountering an error while generating product.g.dart using dart run build_runner build.

[INFO] Found 59 declared outputs which already exist on disk. This is likely because the.dart_tool/build folder was deleted, or you are submitting generated files to your source repository.
Delete these files?
1 - Delete
2 - Cancel build
3 - List conflicts
