multiple chat and message models?

[dmlond]

is it possible to have multiple chat and method models, so that they can have different rails activerecord attributes like belongs_to, or Pundit Policies? Do I just create the following migrations:

db/migrate/1234_create_llm_proposal_reviews.rb

class CreateLLMProposalReviews < ActiveRecord::Migration[8.1]
  def change
    create_table :llm_reviews do |t|
      t.references :ruby_llm_model, null: false, foreign_key: { to_table: :ruby_llm_models }, type: :bigint
      t.references :proposal, nullL false, foreign_key: {to_table: :proposals}
      t.boolean :cancelled, null: false, default: false
      t.timestamps
    end
 end

db/migrate/1234_create_llm_proposal_review_messages.rb

class CreateLLMProposalReviewMessages < ActiveRecord::Migration[8.1]
  def change
    create_table :llm_proposal_review_messages do |t|
      t.references :llm_proposal_review, null: false, foreign_key: { to_table: :llm_proposal_reviews }, type: :bigint
      t.string :role, null: false
      t.text :content
      t.boolean :cache_until_here, null: false, default: false
      t.text :thinking_text
      t.text :thinking_signature

      t.jsonb :citations
      t.jsonb :server_tool_calls
      t.jsonb :raw_content
      t.jsonb :raw_reasoning

      t.string :finish_reason
      t.timestamps
    end
  end
end

db/migrate/1234_create_llm_justification_reviews.rb

 class CreateLLMJustificationReviews < ActiveRecord::Migration[8.1]
  def change
    create_table :llm_reviews do |t|
      t.references :ruby_llm_model, null: false, foreign_key: { to_table: :ruby_llm_models }, type: :bigint
      t.references :justification, nullL false, foreign_key: {to_table: :justifications}
      t.boolean :cancelled, null: false, default: false
      t.timestamps
    end
 end 

db/migrate/1234_create_llm_justification_review_messages.rb

class CreateLLMJustificationReviewMessages < ActiveRecord::Migration[8.1]
 def change
   create_table :llm_justification_review_messages do |t|
     t.references :llm_justification_review, null: false, foreign_key: { to_table: :llm_justification_reviews }, type: :bigint
     t.string :role, null: false
     t.text :content
     t.boolean :cache_until_here, null: false, default: false
     t.text :thinking_text
     t.text :thinking_signature

     t.jsonb :citations
     t.jsonb :server_tool_calls
     t.jsonb :raw_content
     t.jsonb :raw_reasoning

     t.string :finish_reason
     t.timestamps
   end
 end
end

is there a generator for generating these (at least the messages, they have a lot of fields)

[github-actions[bot]]

The install generator creates one application-owned chat/message pair and supports custom class names such as chat:Conversation message:ChatMessage the guide. For separate proposal and justification workflows, use one acts_as_chat model with your own associations and policies, or create distinct chat classes that each declare acts_as_chat; the model registry remains RubyLLM-managed rather than an application model the guide.

would making a single message model with a polymorphic belongs_to be possible? e.g. it can belong to either an LLMJustificationReview or LLMProposalReview?

[github-actions[bot]]

The documented Rails integration expects each chat model to have its own message association; acts_as_message maps to one chat association, not a polymorphic owner. You can use custom message classes or separate associations/tables, but a single polymorphic message model is not a documented supported configuration. the guide
