Adding custom field to listing_searchable_text

1

Hi everyone,

I am using listing to add additional custom fields to samples grid. However, I am stuck as I am not able to add these extra columns to ‘search’ using listing_searchable_text. I have tried below approaches, but listing_searchable_text doesn’t add extra field. I’d appreciate any help.

  1. Using an adapter that implements

    ``IListingSearchableTextProvider``.

# @adapter(IAnalysisRequest, IBikaCatalogAnalysisRequestListing)  # object type + catalog (None is fine)
# @adapter(IAnalysisRequest, IBikaCatalogListing)
@adapter(IAnalysisRequest, ISampleCatalog)
@implementer(IListingSearchableTextProvider)
class ARListingSearchableTextProvider(object):
    """Include PatientFirstName and PatientLastName in listing_searchable_text"""

    def __init__(self, context, catalog=None):
    # def __init__(self, context):
        logger.info("Initializing ARListingSearchableTextProvider")
        self.context = context
        self.catalog = catalog
        # self.PatientFirstName = context.getField('PatientFirstName').get(self.context)

    def __call__(self):
        tokens = []
        logger.info("ARListingSearchableTextProvider: __call__ invoked")
        
        # Patient First Name
        if getattr(self.context, "getPatientFirstName", None):
            logger.info("Getting Patient First Name")
            val = self.context.getPatientFirstName()
            if val:
                tokens.append(val)

        # Patient Last Name
        if getattr(self.context, "getPatientLastName", None):
            logger.info("Getting Patient Last Name")
            val = self.context.getPatientLastName()
            if val:
                tokens.append(val)

        return tokens

  1. by simply calling the function

    `get_searchable_text_tokens`

  2. # @indexer(IAnalysisRequest, ISenaiteCatalogSample)
@indexer(IAnalysisRequest) 
def ar_listing_searchable_text(instance):
    """Indexer for listing_searchable_text on AnalysisRequests"""

    logger.info("Indexing listing_searchable_text for %s", instance.getId())
    
    exclude = []
    include = ["PatientFirstName"]

    tokens = get_searchable_text_tokens(
        instance,
        "senaite_catalog_sample",
        exclude_field_names=exclude,
        include_field_names=include,
    )

    logger.info("Indexer tokens for %s: %s", instance.getId(), tokens)
    return u" ".join(tokens)

Thanks,
