vue+Element项目中v-for循环+表单验证

如果在Form 表单里有通过v-for动态生成，如何设置验证呢？

<el-form ref="ruleFormRef" :model="ruleForm" status-icon :rules="rules" label-width="120px"
                    class="demo-ruleForm" hide-required-asterisk>
<div v-for="(item, index) in ruleForm.input" :key="index">
                        <el-form-item label="活动奖品">
                            <el-form-item :prop="'input.' + index + '.prizename'" :rules="rules.prizename">
                                <el-input v-model="item.prizename" style="width: 165px; margin-right: 10px;"
                                    autocomplete="off" placeholder="请输入奖品名称" clearable>
                                </el-input>
                            </el-form-item>
                            <el-form-item :prop="'input.' + index + '.ptock'" :rules="rules.ptock">
                                <el-input v-model="item.ptock" style="width: 165px; margin-right: 10px;" autocomplete="off"
                                    placeholder="请输入奖品库存" clearable>
                                </el-input>
                            </el-form-item>
                            <el-form-item :prop="'input.' + index + '.odds'" :rules="rules.odds">

                                    placeholder="请输入中奖几率" @change="handleChange" />
                            </el-form-item>
                            <el-form-item :prop="'input.' + index + '.prizelog'" :rules="rules.prizelog">
                                <el-input v-model="item.prizelog" style="width: 165px;" autocomplete="off"
                                    placeholder="请输入奖品数量">
