mysql - 如何从 f.select in rails 中插入选定值

Question

我想在提交表单时将选择标签中的选定值插入到数据库中。

问题是所有值都是从 select 标签中选择的，但是当我提交表单时，只有第一个值总是插入到数据库中，而不是选择的值。

我的_form.html.erb文件

<div class="form-group">
  <label class="control-label">Requirement Type</label>
  <div class="input-group"> <span class="input-group-addon"> <i class="fa fa-globe"></i> </span>
     <%= f.select :job_types, Settings.job_types_for_job_posting.to_a.map { |w| [w.humanize, w] }, {}, class: "form-control" %>
   </div>
</div>

我的枚举在setting.yml文件中定义

job_types_for_job_posting: [Contract, Permanent, On Demand, Internal]

我的jobs_controller.rb文件是

    def create
    @job = current_user.job_postings.build(params_value)

    respond_to do |format|
      if @job.save
        add_or_update_skills
        format.json { render json: { result: true } }
        format.html { redirect_to root_path, notice: 'Job is posted successfully' }
      else
        format.json { render json: { result: false } }
        format.html { render :new }
      end
    end
  end

    params.require(:job_posting).permit(:title, :description, :salary_from, :salary_to, :experience, :experienceto,
                                        :expected,:key,:sourcing,:client_id, :job_assignment,:status, :no_of_opening, :location, :designation, :responsibilities, :job_skills, :industry_id, :functional_area_id, :role_category_id, :job_role_id, :job_types)
  end 

当我准备新工作时，每次只插入“契约(Contract)”表示 0。任何人都可以告诉我，我哪里错了......

(没有测试)我认为你的行应该是:

<%= f.select(:job_types, Settings.job_types_for_job_posting.to_a.collect.with_index { |w, i| [w.humanize, i] }, {}, class: "form-control") %>

数组的索引应该是你的值，对吧？
