Overview

Renders a clickable link to another presenter’s index page, optionally with Ransack filter parameters pre-filled from the current record.

Options:

slug          — static presenter slug (e.g., "import-rows")
model_field   — record field whose value is a model name; resolved to
                 a routable presenter slug at render time
filter        — Hash of Ransack predicate => value template.
                 Value templates starting with ":" are resolved from the
                 record (e.g., ":id" → record.id)
label         — link text (default: humanized slug)
icon          — optional icon name (rendered as <span class="lcp-icon ...">)
css_class     — optional CSS class override (default: "btn btn-sm btn-outline-secondary")

Examples:

# Static slug with filter
field :id, renderer: :record_link, options: {
  slug: "import-rows",
  filter: { "job_execution_id_eq" => ":id" },
  label: "Import Rows", icon: "list"
}

# Dynamic slug from model field
field :target_model, renderer: :record_link, options: {
  model_field: "target_model",
  filter: { "import_rows_job_execution_id_eq" => ":id" },
  label: "Imported Records", icon: "external-link"
}
