映射时嵌套数据表

Question

Basically I have two tables products and categories . I managed to map out products with:

var ProductsList = React.createClass({
render: function () {
    var EachProduct = this.props.data.map(function (item) {
        return (
                <SingleProduct key={item.Id } data={item}/>
        );
    });
    return (
        <ul>
            {EachProduct}
        </ul>
        );
}

});

...and there is yet that second table categories . I tried googling but I did not really knew how to google it. Normally I could just send two models to view from controller and could just do foreach in foreach and the second one would just look into categories for fk_product_id or something like that, so that <SingleProduct/> class could show all categories that are connected with mapped product ..but this is just a different story.

How to do that?

Answer 1

Maybe something like this would help:

render: function () {
var EachProduct = this.props.data.map(function (item) {
    var category = this.props.categories.find((categoryItem)=>{
         return (item.categoryId === categoryItem.id)
    })
    return (
            <SingleProduct key={item.Id } data={item} category={category}/>
    );
});
return (
    <ul>
        {EachProduct}
    </ul>
    );

}
