ActiveAdmin不保存has_many嵌套对象 [英] ActiveAdmin not saving has_many nested object
问题描述
我似乎无法找出为什么我的has_many
记录无法保存的原因.我已经在模型中使用has_one
进行了测试,它可以正常工作,但是当我将其更改为has_many
时,它将无法正常工作.我检查了一些类似的stackoverflow帖子,并且我似乎有正确的用法,但是它不起作用. activeadmin中的嵌套表格未保存更新& ActiveAdmin表单未保存嵌套对象
I cannot seem to find out why my has_many
record will not save. I've test with has_one
in the models and it works fine but when I change it to has_many
it doesn't work. I've check a few simular stackoverflow posts and I seem to have this correct but it doesn't work. Nested form in activeadmin not saving updates & ActiveAdmin Form not saving nested object
这是用于Rails version 5.1.0.alpha
和Activeadmin version 1.0.0.pre4
我没有得到任何错误,也没有看到嵌套对象的创建,尽管在创建对象时看到的参数是输出
I do not get any errors nor do I see the nested object get created though I see the params when I create an object here is the output

更新
我只是在Rails控制台中进行了测试,但工作正常(仍然无法通过ActiveAdmin浏览器工作
I just testing in the rails console and it worked fine (still does not work through ActiveAdmin browser

推荐答案
我能够通过添加 ActiveAdmin.register
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
这只是一个补丁.请注意,它起作用的唯一方法是使用.as_json
它不适用于to_json
或仅适用于参数
This is just a patch. Notice and the only way it worked is if I used .as_json
it would not work with to_json
or just the params alone
