create.json.jbuilder 没有返回对象？

Question

def create
    @practice = Practice.new(practice_params)

    if @practice.save && @practice.start
      respond_to do |format|
        format.html { redirect_to practice_learnings_path(@practice) && return }
        format.json
      end
    else
      redirect_to practices_path
    end
  end

//create.json.jbuilder
json.practice @practice

Answer 1

您需要为此 create 操作创建新的视图文件，即 create.json.jbuilder 在 views/pratices 下。将您的代码写到 return json。

例如：

# app/views/practices/create.json.jbuilder

json.practise do
  json.attr1 @practice.attr1
  json.attr2 @practice.attr2
  json.attr3 @practice.attr3
end
