def ai_fill_analysis_attachments(analysis)
  analysis.children.where(container_type: 'dataset').flat_map do |dataset|
    Attachment.where(attachable_type: 'Container', attachable_id: dataset.id).to_a
  end
end

#ai_fill_analysis_text(element, container_id) ⇒ Object

The container id must be one of the element's own analysis containers. Then concatenate the extracted text of every attachment on that analysis's dataset children, each prefixed "### ", with the analysis name/description prepended as context. Cap at AiTemplate::MAX_FILES; skip unreadable files.

end

#ai_fill_attachment_text(element, attachment_id) ⇒ Object

The attachment must be one of the element's own attachments OR an attachment of one of the element's analysis DATASET containers. Only then is it read.

#ai_fill_dataset_containers(element) ⇒ Object

Dataset containers under all of the element's analysis containers.

def ai_fill_dataset_containers(element)
  element.analyses.flat_map { |analysis| analysis.children.where(container_type: 'dataset').to_a }
end

#ai_fill_element_attachment_ids(element) ⇒ Object

Ids of attachments this element may expose to the AI fill: its own attachments plus the attachments of its analysis dataset containers.

  own = element.attachments.pluck(:id)
  dataset_ids = ai_fill_dataset_containers(element).map(&:id)
  dataset_att = dataset_ids.empty? ? [] : Attachment.where(attachable_type: 'Container', attachable_id: dataset_ids).pluck(:id)
  (own + dataset_att).uniq
end

#ai_fill_element_data(params, current_user) ⇒ Object

AI auto-fill of a generic element instance's DATA VALUES from a document (an existing attachment, an analysis, or freshly uploaded files). Reads the source text, asks the LLM to extract values for the element's OWN template fields, validates them, and returns them for the client to merge into the working copy for human review. Nothing is persisted here.

Authorization: the caller must be able to READ the element, and the source must BELONG to that element (see the ownership checks below) — this endpoint reads files by id, so it must never read an Attachment/Container the user does not already have access to through this element.

#create_ai_element_klass(params, current_user) ⇒ Object

Create a new (inactive) element klass whose properties template is generated by an LLM from a user-provided name/label plus optional description, reference links and uploaded files. The admin reviews/edits the generated template in the designer and activates it (human-in-the-loop).
