    Question

    There is a task ā€” to send files from a table via email:

    =: emailSend(to: "test@example.ru"; title: "Some email"; body: "test"; files: #file_field)

    How can I send files from multiple rows of a table if I retrieved them using selectlist?

    Answer

    You have several rows, each with a file field containing one or more files, and you need to send them from multiple rows simultaneously. Therefore, the array of lists obtained with selectList needs to be concatenated using listTrain (to get a one-dimensional list).

    Example of code for sending an email:

    =: emailSend(to: "test@example.ru"; title: "Some email"; body: "test"; files: $train)

train: listTrain(list: $list)
    list: selectList(table: $#ntn; field: 'file_field'; where: 'file_field' != $#lc)
