How can I save the currentRating in rails

[kerbong]

Hi, Iam so exhausted about it... I tried so much. Pls help me.

its my _form.html.erb

I wanna make this system.
If user select "star-rating", it is automatley filled by rating score (like 3.5)

then user write title and desc. If user click "submit" button, then review(has title/desc/star-rating) should be created.
But, I don't know how can I grab currentRating and put it in :rating params...

(when I've been tested it, I can save ca_review but there is no :rating value... it was always nil...)

I'm using rails6.

bottom of _form.html.erb

<script> $(function() { $(".my-rating").starRating({ initialRating: 3.5, strokeColor: '#894A00', strokeWidth: 10, starSize: 35, starShape: 'rounded', onHover: function(currentIndex, currentRating, $el){ $('.live-rating').text(currentIndex); }, onLeave: function(currentIndex, currentRating, $el){ $('.live-rating').text(currentRating); const c_rating = currentRating; } }); }); </script>

middle of _form.html.erb

<%= form_with(url: care_article_ca_reviews_path, class: "shadow p-3 mb-3 bg rounded", local: true) do |f| %>

<%= obj %>

	<div class="form-group row" style= "font-size:1.5em; padding-left:1em; margin-bottom:-1em;">
      <%= f.label :rating, "평점", class: "col-12 col-form-label text-light" %>
		<div class="text-light" style= "font-size:0.5em; padding-left: 15px;"> 
			(0.5점 단위로 가능하고 한 번 누르면 고정됩니다)
		</div>
      <div class="col-11">
		<!-- 별 평점 매기기 -->
	  	<div class="my-rating jq-star" style="text-align:center;" name="rating" id="rating">
	    </div>
		<div style="text-align:center;">
			 <label class= "live-rating padding-left:4em;" ></label>
			 <%= number_field_tag 'rating', "", class: "live-rating" %>
		</div>
      </div>

```

ca_reviews_controller.rb

  def create 
    @ca_review = CaReview.new(title: params[:title], review: params[:review], care_article_id: params[:care_article_id], user_id: current_user.id, rating: params[:rating])

    respond_to do |format|
      if @ca_review.save
        format.html { redirect_to care_article_path(@care_article), notice: '돌봄 후기가 성공적으로 저장되었습니다.' }
        format.json { render :show, status: :created, location: @ca_review }
      else
        format.html { render :new }
        format.json { render json: @ca_review.errors, status: :unprocessable_entity }
      end
    end
  end
