Multiple create of one model in single form - ruby-on-rails

Question

Hello I am building ROR Survey application for survey. I am having a problem of saving multiple objects into my database.My paramters after submission look all good but instead get an error of:
undefined methodpermit' for #Array:0x00007ff29d873010`
My parameters look like
Parameters: {
"utf8"=>"✓",
"authenticity_token"=>"vdUPSIU43ex1Wx3qZB4Xr6qNEaG0FbEyK2tkJ9OCcAtxK3jHe5lKVohS9JFOdpx/cISwIvzAKTRGw5zxUUS4QA==",
"survey_response"=>[
{"user_id"=>"1", "survey_question_id"=>"22", "answer"=>"Hello"},
{"user_id"=>"1", "survey_question_id"=>"23", "answer"=>"Hello"}],
"commit"=>"Create Survey response"
}
My survey_response_params methods is
def survey_response_params
params.require(:survey_response).permit(:answer, :survey_question_id, :user_id, :survey_answer_id)
end
My controller looks like :
class SurveyResponsesController < ApplicationController
def index
#survey_responses = SurveyResponse.all
end
def show
end
def new
#survey_response = SurveyResponse.new
#survey = Survey.find(1)
#survey_questions = #survey.survey_questions
end
def edit
#survey = Survey.find(1)
#survey_questions = #survey.survey_questions
end
def create
#survey_response = SurveyResponse.new(survey_response_params)
respond_to do |format|
if #survey_response.save
format.html { redirect_to #survey_response, notice: 'Survey response was successfully created.' }
format.json { render :show, status: :created, location: #survey_response }
else
format.html { render :new }
format.json { render json: #survey_response.errors, status: :unprocessable_entity }
end
end
end
def update
respond_to do |format|
if #survey_response.update(survey_response_params)
format.html { redirect_to #survey_response, notice: 'Survey response was successfully updated.' }
format.json { render :show, status: :ok, location: #survey_response }
else
format.html { render :edit }
format.json { render json: #survey_response.errors, status: :unprocessable_entity }
end
end
end
def destroy
#survey_response.destroy
respond_to do |format|
format.html { redirect_to survey_responses_url, notice: 'Survey response was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_survey_response
#survey_response = SurveyResponse.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def survey_response_params
params.permit(survey_response: [:answer, :survey_question_id, :user_id, :survey_answer_id])
end
end
Model
class SurveyResponse < ApplicationRecord
belongs_to :survey_question
belongs_to :user
end

You need to change your strong params, for array it looks like:
def survey_response_params
params.permit(survey_response: [:answer, :survey_question_id, :user_id, :survey_answer_id])
end
UPDATE:
I don't know anything about your models and controller, but I think it should be something like this in the controller
survey_response_params[:survey_response].each do |attrs|
SurveyResponse.new(attrs)
end
