Purpose

This function queries a Neo4j database to fetch text translation nodes. It's designed for retrieving translation data stored in a graph database structure, useful for applications dealing with multilingual content, localization systems, or knowledge graphs containing translation information. The function provides a simple interface to access translation nodes with pagination support through the limit parameter.

Source Code

def get_all_dbo_texttranslations(limit=100):
    """Return dbo_TextTranslations nodes (limited to 25)"""
    query = """
    MATCH (n:dbo_TextTranslations)
    RETURN n
    LIMIT $limit
    """
    return run_query(query, {"limit": limit})

Parameters

Name Type Default Kind
limit - 100 positional_or_keyword

Parameter Details

limit: Integer value that controls the maximum number of dbo_TextTranslations nodes to return from the database. Default is 100. Note: The docstring incorrectly states 'limited to 25', but the actual default is 100. This parameter allows for pagination and prevents overwhelming the system with large result sets.

Return Value

Returns the result of run_query() function execution. The exact return type depends on the run_query implementation, but typically would be a list of Neo4j node records or a result object containing dbo_TextTranslations nodes. Each node likely contains properties related to text translations such as source text, translated text, language codes, and other metadata. If no nodes are found, it would return an empty result set.

Dependencies

  • neo4j

Required Imports

from neo4j import GraphDatabase

Usage Example

# Assuming run_query is defined and Neo4j connection is configured
# Example 1: Get default 100 translations
translations = get_all_dbo_texttranslations()
for record in translations:
    print(record['n'])

# Example 2: Get only 10 translations
limited_translations = get_all_dbo_texttranslations(limit=10)

# Example 3: Get maximum translations
all_translations = get_all_dbo_texttranslations(limit=1000)

Best Practices

  • The docstring contains incorrect information (states 'limited to 25' but default is 100) - should be updated for accuracy
  • Consider adding type hints for better code documentation: def get_all_dbo_texttranslations(limit: int = 100) -> List[Dict]
  • Validate that limit is a positive integer to prevent invalid queries
  • Consider adding error handling for database connection issues
  • The function depends on run_query() which must be properly implemented with Neo4j connection management
  • For production use, consider adding logging to track query execution
  • Be mindful of memory usage when setting high limit values
  • Consider implementing proper pagination with offset support for large datasets
