Question

我定义了这个状态：

 constructor(props){
        super(props);

        this.state = {
            open: false,
            customers:[],
            customer:{},
            products:[],
            product:{},
            orders:[],
            order:{},
            newForm:true,
            phoneNumbererror:null,
            shop:this.props.salon,
            value:'a',
            showTab:'none',
            slideIndex: 0,

        };
    }

使用包含fetch的以下函数，我收到一个带有responseData的对象数组：

getProducts(){
        fetch(
            DOMAIN+'/api/products/', {
                method: 'get',
                dataType: 'json',
                headers: {
                    'Accept': 'application/json',
                    'Content-Type': 'application/json',
                    'Authorization':'Bearer '+this.props.token
                }
            })
            .then((response) => response.json())
            .then((responseData) => {
                this.setState({products:responseData})
                console.log("Console log de products responseData");
                console.log(responseData);
            })
            .catch(function(e) {
                console.log(e);
            });
    }

此功能在componentDidMount：

中调用

componentDidMount(){
        this.getCustomers();
        this.getProducts();
    }

从fetch中获取并保存在this.state.products内的JSON对象如下所示：

如前面提到的那样，使用此行this.setState({products:responseData})我可以将products传递到我希望显示name和price的表格：

<DataTables
     height={'auto'}
     selectable={false}
     showRowHover={true}
     columns={FAV_TABLE_COLUMNS}
     data={this.state.products}
     showCheckboxes={false}
     rowSizeLabel="Filas por página"
           />

名为：

const FAV_TABLE_COLUMNS = [
    {
        key: 'name',
        label: 'Producto'
    }, {
        key: 'price',
        label: 'Precio del producto'
    }
];

如何过滤产品以仅显示客户最喜欢的产品？

客户端的所有最喜欢的产品都存储在数组favouritesProducts中的另一个对象中：

该对象是通过其他功能获得的：

getCustomers(){
        fetch(
            DOMAIN+'/api/customers/shop/'+this.props.salon, {
                method: 'get',
                dataType: 'json',
                headers: {
                    'Accept': 'application/json',
                    'Content-Type': 'application/json',
                    'Authorization':'Bearer '+this.props.token
                }
            })
            .then((response) =>
            {
                return response.json();
            })
            .then((responseData) => {
                responseData.map(function (v) {
                    v.platform = v.app ? v.app.platform : null  })
                this.setState({customers:responseData})
                console.log(responseData);
            })
            .catch(function() {
                console.log("error");
            });
    }

目前我可以在没有过滤器的情况下打印所有产品。问题是如何使用客户喜欢的产品过滤我获得的产品。

我的上一次尝试是loadfavs()而不是getProducts()：

loadFavs(){
        let favs = this.state.customer.favouritesProducts || [];
        const listOfFavProds = favs.map((element) => {
            console.log("log de element en loadfavs");
            console.log(element);
            this.getProduct();
            fetch(
                DOMAIN + '/api/products/' + element, {
                    method: 'get',
                    dataType: 'json',
                    headers: {
                        'Accept': 'application/json',
                        'Content-Type': 'application/json',
                        'Authorization': 'Bearer ' + this.props.token
                    }
                })
                .then((response) => response.json())
                .then((responseData) => {
                    this.setState({products: responseData})
                    console.log("Console log de products");
                    console.log(responseData);
                })
                .catch(function (e) {
                    console.log(e);
                });
        })
    }

当我按下“消除”按钮时会调用它（是的，我已经将其删除功能替换为更容易测试）：

    <FlatButton
        label='Eliminar'
        secondary={true}
        onTouchTap={this.loadFavs}
    />

但是最后一次尝试我只得到一个新的错误：

TypeError: data.map is not a function

并发出警告：

Warning: Failed prop type: Invalid prop `data` of type `object` supplied to `DataTables`, expected `array`.
