Rails 6 с текстом Action и Active Storage не обрабатывает как создание, а CheckpointsController # new как HTML

Question

Таким образом, форма не сохраняется в БД. Не уверен, почему, но он обрабатывается как: CheckpointsController#new as HTML

Вот форма:

<div class="card">
  <div class="card-header" style='background-color: #3b3a39; color: whitesmoke;'>
    Checkpoint
  </div>
  <div class="card-body">
    <form>
      <%= form_with(model: checkpoint, local: true, remote: true) do |form| %>
        <% if checkpoint.errors.any? %>
          <div id="error_explanation">
            <h2><%= pluralize(checkpoint.errors.count, "error") %> prohibited this checkpoint from being saved:</h2>

            <ul>
              <% checkpoint.errors.full_messages.each do |message| %>
                <li><%= message %></li>
              <% end %>
            </ul>
          </div>
        <% end %>

        <div class="form-group">
          <%= form.label :section_id %>
          <%= form.collection_select :section_id, Section.order(:name), :id, :name, include_blank: true, input_html: { class: "dropdown" } %>
        </div>

        <div class="form-group">
            <%= form.label :title %>
            <%= form.text_field :title, class: "form-control" %>
        </div>

        <div class="form-group">
          <%= form.label :description %>
          <%= form.text_area :description, class: "form-control" %>
        </div>

        <div class="form-group">
          <%= form.label :time_to_complete, "Time to complete as percentage of section" %>
          <%= form.number_field :time_to_complete, class: "form-control" %>
        </div>

        <div>
          <%= form.label :content %>
          <%= form.rich_text_area :content %>
        </div>
        <br />

        <div class="form-group">
          <%= form.button :submit, class: "btn btn-outline-success pull-right" %>
        </div>
      <% end %>
    </form>
  </div>
</div>

Вот контроллер:

class CheckpointsController < ApplicationController
  before_action :set_checkpoint, only: [:show, :edit, :update, :destroy]

  # GET /checkpoints
  # GET /checkpoints.json
  def index
    @checkpoints = Checkpoint.all
  end

  # GET /checkpoints/1
  # GET /checkpoints/1.json
  def show
  end

  # GET /checkpoints/new
  def new
    @checkpoint = Checkpoint.new
    @sections = Section.all
  end

  # GET /checkpoints/1/edit
  def edit
    @sections = Section.all
  end

  # POST /checkpoints
  # POST /checkpoints.json
  def create
    @checkpoint = Checkpoint.new(checkpoint_params)
    @section = Section.find(checkpoint_params[:section_id])
    @course = @section.course

    respond_to do |format|
      if @checkpoint.save
        format.html { redirect_to @course, notice: 'Checkpoint was successfully created.' }
        format.json { render :show, status: :created, location: @checkpoint }
      else
        format.html { render :new }
        format.json { render json: @checkpoint.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /checkpoints/1
  # PATCH/PUT /checkpoints/1.json
  def update
    respond_to do |format|
      if @checkpoint.update(checkpoint_params)
        format.html { redirect_to @checkpoint, notice: 'Checkpoint was successfully updated.' }
        format.json { render :show, status: :ok, location: @checkpoint }
      else
        format.html { render :edit }
        format.json { render json: @checkpoint.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /checkpoints/1
  # DELETE /checkpoints/1.json
  def destroy
    @checkpoint.destroy
    respond_to do |format|
      format.html { redirect_to checkpoints_url, notice: 'Checkpoint was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_checkpoint
      @checkpoint = Checkpoint.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def checkpoint_params
      params.require(:checkpoint).permit(:title, :section_id, :description, :time_to_complete, :content)
    end
end

Вотстек вывода:

Я обнаружил, когда перетаскиваю изображение в редактор trix, которое оно сохраняет. Но форма не обрабатывается созданием в контроллере. Не уверен, почему это происходит. Любая помощь будет очень полезна.
