建立vue-admin前端页面

1、编写api->position.js

import request from '@/utils/request'

export function getPositionAll() {
  return request({
    url: '/aivisit/position/',
    method: 'get'
  })
}

export function createPosition(data) {
  return request({
    url: '/aivisit/position/',
    method: 'post',
    data
  })
}

export function updatePosition(id, data) {
  return request({
    url: `/aivisit/position/${id}/`,
    method: 'put',
    data
  })
}

export function deletePosition(id) {
  return request({
    url: `/aivisit/position/${id}/`,
    method: 'delete'
  })
}

2、编写views->demo->position.vue

<template>
  <div class="app-container">
    <div>
      <el-input
        v-model="search"
        placeholder="输入岗位名称进行搜索"
        style="width: 200px"
        class="filter-item"
        @keyup.native="handleFilter"
      />
      <el-button
        type="primary"
        icon="el-icon-plus"
        @click="handleAdd"
        v-if="checkPermission(['position_create'])"
        size="small"
        >新增</el-button
      >
    </div>
    <el-table
      v-loading="listLoading"
      :data="
        tableData.filter(
          (data) =>
            !search || data.name.toLowerCase().includes(search.toLowerCase())
        )
      "
      style="width: 100%; margin-top: 10px"
      highlight-current-row
      row-key="id"
      height="100"
      stripe
      border
      v-adaptive="{ bottomOffset: 50 }"
    >
      <el-table-column type="index" width="50" />
      <el-table-column label="岗位名称">
        <template slot-scope="scope">{{ scope.row.name }}</template>
      </el-table-column>
      <el-table-column label="创建日期">
        <template slot-scope="scope">
          <span>{{ scope.row.create_time }}</span>
        </template>
      </el-table-column>
      <el-table-column align="center" label="操作">
        <template slot-scope="scope">
          <el-button
            type="primary"
            size="small"
            icon="el-icon-edit"
            :disabled="!checkPermission(['position_update'])"
            @click="handleEdit(scope)"
          />
          <el-button
            type="danger"
            size="small"
            icon="el-icon-delete"
            :disabled="!checkPermission(['position_delete'])"
            @click="handleDelete(scope)"
          />
        </template>
      </el-table-column>
    </el-table>

    <el-dialog
      :visible.sync="dialogVisible"
      :title="dialogType === 'edit' ? '编辑岗位' : '新增岗位'"
    >
      <el-form
        ref="Form"
        :model="position"
        label-width="80px"
        label-position="right"
        :rules="rule1"
      >
        <el-form-item label="名称" prop="name">
          <el-input v-model="position.name" placeholder="名称" />
        </el-form-item>
      </el-form>
      <span slot="footer">
        <el-button type="danger" @click="dialogVisible = false">取消</el-button>
        <el-button type="primary" @click="confirm('Form')">确认</el-button>
      </span>
    </el-dialog>
  </div>
</template>

<script>
import {
  getPositionAll,
  createPosition,
  deletePosition,
  updatePosition,
} from "@/api/position";
import { genTree, deepClone } from "@/utils";
import adaptive from '@/directive/el-table'
import checkPermission from "@/utils/permission";

const defaultM = {
  id: "",
  name: "",
};
export default {
  directives: { adaptive },
  data() {
    return {
      position: {
        id: "",
        name: "",
      },
      search: "",
      tableData: [],
      positionList: [],
      listLoading: true,
      dialogVisible: false,
      dialogType: "new",
      rule1: {
        name: [{ required: true, message: "请输入名称", trigger: "blur" }],
      },
    };
  },
  computed: {},
  created() {
    this.getList();
  },
  methods: {
    checkPermission,
    getList() {
      this.listLoading = true;
      getPositionAll().then((response) => {
        console.log(response)
        this.positionList = response.data;
        this.tableData = response.data;
        this.listLoading = false;
      }).catch(err => {
        // 报错
        console.log(err)
      })
      ;
    },
    resetFilter() {
      this.getList();
    },
    handleFilter() {
      const newData = this.positionList.filter(
        (data) =>
          !this.search ||
          data.name.toLowerCase().includes(this.search.toLowerCase())
      );
      this.tableData = genTree(newData);
    },
    handleAdd() {
      this.position = Object.assign({}, defaultM);
      this.dialogType = "new";
      this.dialogVisible = true;
      this.$nextTick(() => {
        this.$refs["Form"].clearValidate();
      });
    },
    handleEdit(scope) {
      this.position = Object.assign({}, scope.row); // copy obj
      this.dialogType = "edit";
      this.dialogVisible = true;
      this.$nextTick(() => {
        this.$refs["Form"].clearValidate();
      });
    },
    handleDelete(scope) {
      this.$confirm("确认删除?", "警告", {
        confirmButtonText: "确认",
        cancelButtonText: "取消",
        type: "error",
      })
        .then(async () => {
          await deletePosition(scope.row.id);
          this.getList();
          this.$message({
            type: "success",
            message: "成功删除!",
          });
        })
        .catch((err) => {
          console.error(err);
        });
    },
    async confirm(form) {
      this.$refs[form].validate((valid) => {
        if (valid) {
          const isEdit = this.dialogType === "edit";
          if (isEdit) {
            updatePosition(this.position.id, this.position).then(() => {
              this.getList();
              this.dialogVisible = false;
              this.$message({
                message: "编辑成功",
                type: "success",
              });
            });
          } else {
            createPosition(this.position).then((res) => {
              // this.position = res.data
              // this.tableData.unshift(this.position)
              this.getList();
              this.dialogVisible = false;

            });
          }
        } else {
          return false;
        }
      });
    },
  },
};
</script>

3、加菜单router->index.js

  {
    path: '/position',
    component: Layout,
    redirect: '/demo/position',
    children: [
      {
        path: 'index',
        component: () => import('@/views/demo/position'),
        name: 'Position',
        meta: { title: '岗位管理', icon: 'guide', noCache: true }
      }
    ]
  },

4、配置服务端.env.development

# just a flag
ENV = 'development'

# base api
VUE_APP_BASE_API = 'http://127.0.0.1:8000/api'

4、 遇到的坑：页面获取不到json

utils->request.js

    // if the custom code is not 20000, it is judged as an error.
    if (res.code !== 20000 && res.code !== 0 && res.code !== 200) {  //原来只有 res.code !== 20000
      Message({
        message: res.message || 'Error',
        type: 'error',
        duration: 5 * 1000
      })

5、遇到的坑：没有实现表格页面缩放

position.vue

import adaptive from '@/directive/el-table'
export default {
  directives: { adaptive },
  data() {
	....
  }
}

    <el-table
      v-loading="listLoading"
      :data="
        tableData.filter(
          (data) =>
            !search || data.name.toLowerCase().includes(search.toLowerCase())
        )
      "
      style="width: 100%; margin-top: 10px"
      highlight-current-row
      row-key="id"
      height="100"
      stripe
      border
      v-adaptive="{ bottomOffset: 50 }"  //原代码有错，应该是v-adaptive
    >
