经典前端+后端+表头+表身的开发实战参考简易模板【珍藏】
前端部分(Vue 3 + Element Plus)
1. 修改
MPS002HList.vue
(主生产计划列表)
a. 添加查询表单
在模板中添加查询表单,包含产品料号、品名、规格和年月的输入项。
<template> <div> <!-- 查询表单 --> <el-form :inline="true" :model="filters" class="demo-form-inline"> <el-form-item label="产品料号"> <el-input v-model="filters.bo_no" placeholder="请输入产品料号"></el-input> </el-form-item> <el-form-item label="品名"> <el-input v-model="filters.item_name" placeholder="请输入品名"></el-input> </el-form-item> <el-form-item label="规格"> <el-input v-model="filters.item_spec" placeholder="请输入规格"></el-input> </el-form-item> <el-form-item label="年月"> <el-date-picker
v-model="filters.mps_ym"type="month"placeholder="选择年月"format="yyyy-MM"value-format="yyyy-MM" /> </el-form-item> <el-form-item> <el-button type="primary" @click="fetchMpsList">查询</el-button> <el-button @click="resetFilters">重置</el-button> </el-form-item> </el-form> <!-- 生产计划列表 --> <el-table :data="mpsList" style="width: 100%" v-loading="loading"> <el-table-column prop="mps_no" label="单号" width="180"> <template #default="{ row }"> <el-button type="text" @click="showMpsDetails(row.mps_no)">{{ row.mps_no }}</el-button> </template> </el-table-column> <el-table-column prop="mps_date" label="单据时间" width="180" /> <el-table-column prop="fa_no_name" label="厂别" width="180" /> <el-table-column prop="bo_no" label="产品料号" width="180" /> <el-table-column prop="bo_no_name" label="品名" width="180" /> <el-table-column prop="bo_no_spec" label="规格" width="180" /> <el-table-column prop="mps_ym" label="年月" width="100" /> <el-table-column prop="mps_qty" label="数量" width="100" /> </el-table> <!-- 分页 --> <el-pagination
v-if="mpsList.length"background
:current-page="page":page-size="pageSize"layout="total, prev, pager, next":total="total"@current-change="handlePageChange" /> <!-- 详情对话框 --> <el-dialog :visible.sync="showDetails" width="80%"> <template #header> <h3>主生产计划详情</h3> </template> <MPS002HDetail :mps_no="selectedMpsNo" /> </el-dialog> </div> </template>
b. 修改脚本部分
在
setup
函数中,添加
filters
数据,并修改
fetchMpsList
函数以包含查询参数。
<script>import { ref, onMounted } from'vue';
import { getMPS002 } from'@/api/mpsApp/MPS002HModel';
import MPS002HDetail from'./MPS002HDetail.vue';
exportdefault{
components: { MPS002HDetail },
setup() {
const mpsList=ref([]);
const page= ref(1);
const pageSize= ref(10);
const total= ref(0);
const loading= ref(false);
const showDetails= ref(false);
const selectedMpsNo= ref(null);
const filters=ref({
bo_no:'',
item_name:'',
item_spec:'',
mps_ym:'',
});
const fetchMpsList= async () =>{
loading.value= true;try{
const params={
page: page.value,
page_size: pageSize.value,
bo_no: filters.value.bo_no,
item_name: filters.value.item_name,
item_spec: filters.value.item_spec,
mps_ym: filters.value.mps_ym,
};
const response=await getMPS002(params);
mpsList.value=response.data.results;
total.value=response.data.count;
}catch(error) {
console.error('Error fetching MPS002 list:', error);
}finally{
loading.value= false;
}
};
const resetFilters= () =>{
filters.value={
bo_no:'',
item_name:'',
item_spec:'',
mps_ym:'',
};
fetchMpsList();
};
const showMpsDetails= (mps_no) =>{
selectedMpsNo.value=mps_no;
showDetails.value= true;
};
const handlePageChange= (newPage) =>{
page.value=newPage;
fetchMpsList();
};
onMounted(fetchMpsList);return{
mpsList,
page,
pageSize,
total,
loading,
showDetails,
selectedMpsNo,
filters,
fetchMpsList,
resetFilters,
showMpsDetails,
handlePageChange,
};
},
};</script>
2. 修改
MPS002D1List.vue
(物料需求明细列表)
a. 添加查询表单
<template> <div> <!-- 查询表单 --> <el-form :inline="true" :model="filters" class="demo-form-inline"> <el-form-item label="料号"> <el-input v-model="filters.item_no" placeholder="请输入料号"></el-input> </el-form-item> <el-form-item label="品名"> <el-input v-model="filters.item_name" placeholder="请输入品名"></el-input> </el-form-item> <el-form-item label="规格"> <el-input v-model="filters.item_spec" placeholder="请输入规格"></el-input> </el-form-item> <el-form-item> <el-button type="primary" @click="fetchMpsD1List">查询</el-button> <el-button @click="resetFilters">重置</el-button> </el-form-item> </el-form> <!-- 物料需求明细列表 --> <el-table :data="mpsD1List" style="width: 100%" v-loading="loading"> <el-table-column prop="item_no" label="料号" width="180" /> <el-table-column prop="item_name" label="品名" width="180" /> <el-table-column prop="item_spec" label="规格" width="180" /> <el-table-column prop="item_qty" label="需求数量" width="180" /> <!-- 添加更多列 --> </el-table> <!-- 分页 --> <el-pagination
v-if="mpsD1List.length"background
:current-page="page":page-size="pageSize"layout="total, prev, pager, next":total="total"@current-change="handlePageChange" /> </div> </template>
b. 修改脚本部分
<script>import { ref, onMounted } from'vue';
import { getMPS002D1 } from'@/api/mpsApp/MPS002D1Model';
exportdefault{
setup() {
const mpsD1List=ref([]);
const page= ref(1);
const pageSize= ref(10);
const total= ref(0);
const loading= ref(false);
const filters=ref({
item_no:'',
item_name:'',
item_spec:'',
});
const fetchMpsD1List= async () =>{
loading.value= true;try{
const params={
page: page.value,
page_size: pageSize.value,
item_no: filters.value.item_no,
item_name: filters.value.item_name,
item_spec: filters.value.item_spec,
};
const response=await getMPS002D1(params);
mpsD1List.value=response.data.results;
total.value=response.data.count;
}catch(error) {
console.error('Error fetching MPS002D1 list:', error);
}finally{
loading.value= false;
}
};
const resetFilters= () =>{
filters.value={
item_no:'',
item_name:'',
item_spec:'',
};
fetchMpsD1List();
};
const handlePageChange= (newPage) =>{
page.value=newPage;
fetchMpsD1List();
};
onMounted(fetchMpsD1List);return{
mpsD1List,
page,
pageSize,
total,
loading,
filters,
fetchMpsD1List,
resetFilters,
handlePageChange,
};
},
};</script>
后端部分(Django REST Framework)
为了支持前端的查询功能,需要在后端的视图中添加筛选功能。
1. 修改
MPS002HModel
的视图
from rest_framework import viewsets, filters
from django_filters.rest_framework import DjangoFilterBackend
from .models import MPS002HModel
from .serializers import MPS002HSerializer
class MPS002HViewSet(viewsets.ModelViewSet):
queryset= MPS002HModel.objects.all().order_by('-mps_date')
serializer_class=MPS002HSerializer
filter_backends=[DjangoFilterBackend, filters.SearchFilter]
filterset_fields= ['mps_ym']
search_fields= ['bo_no__item_no', 'bo_no__item_name', 'bo_no__item_spec']
说明
- filter_backends
:使用
DjangoFilterBackend
和
SearchFilter
,可以实现精确过滤和模糊搜索。 - filterset_fields
:精确过滤的字段,这里包括
mps_ym
。 - search_fields
:模糊搜索的字段,包括关联的
bo_no
(产品料号)的
item_no
、
item_name
、
item_spec
。
2. 修改
MPS002D1Model
的视图
from rest_framework import viewsets, filters
from django_filters.rest_framework import DjangoFilterBackend
from .models import MPS002D1Model
from .serializers import MPS002D1Serializer
class MPS002D1ViewSet(viewsets.ModelViewSet):
queryset=MPS002D1Model.objects.all()
serializer_class=MPS002D1Serializer
filter_backends=[DjangoFilterBackend, filters.SearchFilter]
search_fields= ['item_no__item_no', 'item_no__item_name', 'item_no__item_spec']
说明
- search_fields
:对于物料需求明细,可以根据
item_no
(料号)、
item_name
(品名)、
item_spec
(规格)进行模糊搜索。
3. 安装和配置
django-filter
如果还没有安装
django-filter
,需要先安装:
pip install django-filter
并在
settings.py
中添加:
REST_FRAMEWORK ={'DEFAULT_FILTER_BACKENDS': ['django_filters.rest_framework.DjangoFilterBackend']
}
更新序列化器
确保您的序列化器包含必要的字段,以便前端能够正确接收数据。
MPS002HSerializer
from rest_framework import serializers
from .models import MPS002HModel
class MPS002HSerializer(serializers.ModelSerializer):
fa_no_name= serializers.CharField(source='fa_no.fa_name', read_only=True)
bo_no_name= serializers.CharField(source='bo_no.item_name', read_only=True)
bo_no_spec= serializers.CharField(source='bo_no.item_spec', read_only=True)
bo_no= serializers.CharField(source='bo_no.item_no', read_only=True)
class Meta:
model=MPS002HModel
fields= ['id', 'mps_no', 'mps_date', 'fa_no', 'fa_no_name', 'bo_no', 'bo_no_name', 'bo_no_spec', 'mps_ym', 'mps_qty']
MPS002D1Serializer
from rest_framework import serializers
from .models import MPS002D1Model
class MPS002D1Serializer(serializers.ModelSerializer):
item_name= serializers.CharField(source='item_no.item_name', read_only=True)
item_spec= serializers.CharField(source='item_no.item_spec', read_only=True)
item_no= serializers.CharField(source='item_no.item_no', read_only=True)
class Meta:
model=MPS002D1Model
fields= ['id', 'mps_no', 'item_no', 'item_name', 'item_spec', 'item_qty', 'rmk']
更新 API 请求
1. 更新前端 API 调用
在您的 API 请求文件中,确保查询参数能够正确传递。
MPS002HModel
API
import request from '@/utils/request';
const baseUrl= '/mpsApp/MPS002HModel/';
exportfunctiongetMPS002(params) {returnrequest({
url: baseUrl,
method:'get',
params,
});
}
MPS002D1Model
API
import request from '@/utils/request';
const baseUrl= '/mpsApp/MPS002D1Model/';
exportfunctiongetMPS002D1(params) {returnrequest({
url: baseUrl,
method:'get',
params,
});
}
总结
通过上述步骤,我们实现了:
前端
:在
MPS002HModel
和
MPS002D1Model
的列表页面中添加了查询表单,可以根据指定的字段进行筛选,并将查询条件传递给后端。后端
:在 Django REST Framework 的视图中,使用
django-filter
和
SearchFilter
实现了对指定字段的精确过滤和模糊搜索。序列化器
:更新了序列化器,以便在返回数据时包含关联字段的信息,如品名和规格。API 请求
:确保查询参数能够正确地通过前端 API 请求发送到后端。
这样,用户就可以在前端界面上根据产品料号、品名、规格和年月对主生产计划列表进行查询,也可以在物料需求明细列表中根据料号、品名、规格进行筛选。
