【问题描述】：

我使用nestjsx 构建我的Nestjs 项目以创建Restful api。我的 customer.controller.ts

import { Controller } from '@nestjs/common';
import { ApiTags } from '@nestjs/swagger';
import { Crud, CrudController } from '@nestjsx/crud';

import { CustomersService } from './customers.service';
import { Customer } from './entities/customer.entity';

@Crud({
  model: {
    type: Customer,
  },
})
@ApiTags('Customer')
@Controller('customers')
export class CustomersController implements CrudController<Customer> {
  constructor(public service: CustomersService) {}
}

我的 customer.service.ts

import { Injectable } from '@nestjs/common';
import { InjectRepository } from '@nestjs/typeorm';
import { TypeOrmCrudService } from '@nestjsx/crud-typeorm';

import { Customer } from './entities/customer.entity';

@Injectable()
export class CustomersService extends TypeOrmCrudService<Customer> {
  constructor(@InjectRepository(Customer) repo) {
    super(repo);
  }
}

我的客户.controller.ts

import { Controller } from '@nestjs/common';
import { ApiTags } from '@nestjs/swagger';
import { Crud, CrudController } from '@nestjsx/crud';

import { CustomersService } from './customers.service';
import { Customer } from './entities/customer.entity';

@Crud({
  model: {
    type: Customer,
  },
})
@ApiTags('Customer')
@Controller('customers')
export class CustomersController implements CrudController<Customer> {
  constructor(public service: CustomersService) {}
}

customer.entity.ts

import {
  Entity,
  PrimaryGeneratedColumn,
  Column,
} from 'typeorm';

@Entity('tbl_Customers')
export class Customer {
  @PrimaryGeneratedColumn({ type: 'int' })
  CustomerID!: number;

  @Column({ type: 'nvarchar', length: 50 })
  CustomerName!: string;

  @Column({ type: 'nvarchar', length: 50 })
  BillingAddressLine1!: string;

  @Column({ type: 'nvarchar', length: 50 })
  BillingAddressLine2: string | null = null;

  @Column({ type: 'nvarchar', length: 50 })
  City!: string;

  @Column({ type: 'nvarchar', length: 8 })
  PostalCode!: string;
}

只有让 /customers 工作，其他 api 端点将返回 Error: Invalid column name 'undefined'. 我按照从 nestjsx 文档的每一步进行设置，但找不到错误。我还尝试了 setup dto 来替换控制器设置中的实体，但得到了同样的错误。我的项目连接到 mssql 并且连接正常。

【解决方案1】：

经过几个小时的搜索，解决方案是添加

params: {
    CustomerId: {
      field: 'CustomerID',
      type: 'number',
      primary: true,
    },
  },

在控制器中作为主键不是默认id。
