# File 'lib/labimotion/helpers/element_helpers.rb', line 287

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.

    parts << "### #{att.filename}\n#{content}"
  end
  parts.join("\n\n")
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.

  att = Attachment.find(attachment_id)
  Labimotion::FileExtractor.extract_bytes(att.filename, att.read_file)
end

#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.

  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.

end

#ai_fill_instructions(element) ⇒ Object

The template's own auto-fill guidance, from Template settings in the designer. Read from the KLASS rather than the element's copied properties, so editing it takes effect on elements that already exist instead of only on new ones.

#ai_fill_pasted_text(text) ⇒ Object

Text pasted straight into the dialog. Capped like an extracted file so a very long paste cannot blow the model's context or the request budget — the same MAX_FILE_CHARS the file path is held to.

  error!('400 Bad Request', 400) if body.empty?

  body[0, Labimotion::AiTemplate::MAX_FILE_CHARS].to_s
end

#ai_fill_properties(element) ⇒ Object

The element's properties, with the select_options its own fields point at.

An element instance never stores select_options: create and update both delete the key (see create_element/update_element below), because the options belong to the template, not to the instance. The fill prompt lists a select's allowed options so the model can pick one, and reads them out of the properties it is handed — so passing element.properties straight through offered the model an EMPTY list for every select and select-multi field. Nothing to choose from, so those fields came back unfilled, which reads as the AI having ignored them.

properties_release, not the klass's current properties_template: it is the release this element was actually built against, so its option keys are the ones the element's fields reference and the ones the form will accept back. Same source the UI and the exporter read for 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).
