iterate_items

  • async iterate_items(*, offset, limit, clean, desc, fields, omit, unwind, skip_empty, skip_hidden): AsyncIterator[dict]

  • Iterates over items in the dataset according to specified filters and sorting.

    This method allows for asynchronously iterating through dataset items while applying various filters such as skipping empty items, hiding specific fields, and sorting. It supports pagination via offset and limit parameters, and can modify the appearance of dataset items using fields, omit, unwind, skip_empty, and skip_hidden parameters.

    Parameters

    • optionalkeyword-onlyoffset: int = 0

      The number of initial items to skip.

    • optionalkeyword-onlylimit: int | None = None

      The maximum number of items to iterate over. None means no limit.

    • optionalkeyword-onlyclean: bool = False

      If True, removes empty items and hidden fields, equivalent to 'skip_hidden' and 'skip_empty'.

    • optionalkeyword-onlydesc: bool = False

      If set to True, items are returned in descending order, i.e., newest first.

    • optionalkeyword-onlyfields: list[str] | None = None

      Specifies a subset of fields to include in each item.

    • optionalkeyword-onlyomit: list[str] | None = None

      Specifies a subset of fields to exclude from each item.

    • optionalkeyword-onlyunwind: str | None = None

      Specifies a field that should be unwound into separate items.

    • optionalkeyword-onlyskip_empty: bool = False

      If set to True, omits items that are empty after other filters have been applied.

    • optionalkeyword-onlyskip_hidden: bool = False

      If set to True, omits fields starting with the '#' character from the output.

    Returns AsyncIterator[dict]

list_items

  • async list_items(*, offset, limit, clean, desc, fields, omit, unwind, skip_empty, skip_hidden, flatten, view): DatasetItemsListPage

  • Retrieves a paginated list of items from a dataset based on various filtering parameters.

    This method provides the flexibility to filter, sort, and modify the appearance of dataset items when listed. Each parameter modifies the result set according to its purpose. The method also supports pagination through 'offset' and 'limit' parameters.

    Parameters

    • optionalkeyword-onlyoffset: int | None = 0

      The number of initial items to skip.

    • optionalkeyword-onlylimit: int | None = _LIST_ITEMS_LIMIT

      The maximum number of items to return.

    • optionalkeyword-onlyclean: bool = False

      If True, removes empty items and hidden fields, equivalent to 'skip_hidden' and 'skip_empty'.
