我正在使用Google定义API的AngularJS和Rails应用程序。该API返回一个JSON响应。Rails 4未经允许的参数 - JSON数据
我想将JSON响应存储在我的Words表中。我通过我的Angular控制器发布API请求，然后我试图将数据添加到我的Words表中。
当我尝试插入JSON数据时，出现“Unpermitted parameters”错误。我研究过，这似乎是由于Rails 4 nested params。
我已经尝试添加嵌套括号到Word控制器中的word_params方法，但随后得到“不允许的参数：dataType，numToShow，groupNumber，groupResult，sectionType，字典”...这是API响应的一部分。
有没有一种更简单的方法来允许完整的JSON数据，而无需通过并明确定义控制器的word_params方法中的每个嵌套参数？
scheme.rb
create_table "words", force: :cascade do |t|
t.string "title"
t.json "full_data"
t.integer "list_id"
t.datetime "date"
end
字控制器
class WordsController < ApplicationController
respond_to :json
def create
list = List.find(params[:list_id])
word = list.words.create(word_params)
respond_with list, word
end
private
def word_params
params.require(:word).permit(:title, :date, :full_data => {})
end
end
