ActiveAdmin不保存has_many嵌套對象

Question

我似乎無法找出爲什麼我的has_many記錄不會保存。我已在模型中使用has_one進行測試，並且它工作正常，但是當我將其更改爲has_many時，它不起作用。我檢查了幾個simulate stackoverflow的帖子，我似乎有這個正確的，但它不工作。 Nested form in activeadmin not saving updates & ActiveAdmin Form not saving nested object

這是Rails version 5.1.0.alpha和Activeadmin version 1.0.0.pre4

我沒有得到任何錯誤，我也不看嵌套對象獲得創建，雖然我看到PARAMS，當我在這裏創建一個對象是輸出

UPDATE

我只是在軌測試控制檯和它工作得很好（仍然沒有通過ActiveAdmin瀏覽器中工作

Answer 1

我能夠在ActiveAdmin.register添加修補

controller do 
    def create 
     @section = AbqDistricts::District.create!(permitted_params[:abq_district].as_json) 
     redirect_to admin_faq_sections_path, notice: "Section was successfully created!" 
    end 
end 

這只是一個補丁。注意和它的唯一工作方式是如果我使用.as_json 它不會與to_json或只是params
