Javascript I'；我不确定这个项目发生了什么，它在本地工作，但在服务器上有问题

我正在尝试将一个项目从本地移动到服务器，但它不像在本地那样工作，我不知道发生了什么。我有产品，当我编辑它们时，它不会像本地那样从数据库中获取信息，它会将2个非常重要的数字作为0，当我知道数据库中没有这些数字作为0时，价格就无法计算

这是它为产品带来的信息

[ { "country": { "id": 1, "name": "COSTA RICA", "currency_symbol": "CRC" }, "country_id": 1, "margin": 0, "fi": 0 }, 
{ "country": { "id": 2, "name": "NICARAGUA", "currency_symbol": "COR" }, "country_id": 2, "margin": 0, "fi": 0 }, 
{ "country": { "id": 3, "name": "HONDURAS", "currency_symbol": "HNL" }, "country_id": 3, "margin": 0, "fi": 0 } ]

对于数据库中的此产品，其边距和fi为

product_id: 1
country_id: 1
margin: 0.65
fi: 0.50

product_id: 1
country_id: 2
margin: 0.65
fi: 0.50

product_id: 1
country_id: 3
margin: 0.65
fi: 0.50

“编辑产品”是“创建模型”的克隆，由于某些原因，它没有提供应有的信息

这是打开“创建”和“编辑”对话框的函数

showDialog(model) {
    if (this.processing) {
        return;
    }
    if (model) {
        let cloneModel = {...model};
        this._formatModel(cloneModel);
        this.actionText = 'Actualizar';
        this.form = cloneModel
    } else {
        this.dialogTitle = 'Nuevo';
        this.actionText = 'Agregar';
        this._isNew();
            if (this.form.id) {
                this._resetForm();
                this.$refs.form.resetFields()
            }
    }

    this.dialogTitle = this._getDialogTitle(this.form);
    this.dialogVisible = true
}

_formatModel(model) {
    this.productCategories = [];

    this.loadingResource = true;
    this.$http.post(this.baseUrl + '/show/' + model.id).then(
        (res) => {
            this.model.export_factors = this.countries.map((country) => {
            let result = res.body.export_factors.filter((item) => item.country_id === country.id);
            let margin = 0;
            let fi = 0;

            if (result.length > 0) {
                margin = result[0].margin;
                fi = result[0].fi;
            }
            return {
                country: country,
                country_id: country.id,
                margin: margin,
                fi: fi,
            }
        });
        this.model.prices = this.countries.map((country) => {
            let result = res.body.prices.filter((item) => item.country_id === country.id);
            let resultExport = res.body.export_factors.filter((item) => item.country_id === country.id);
            let price = 0;

            if (result.length > 0) {
                price = (this.form.cif / resultExport[0].margin) / resultExport[0].fi;
            }
            return {
                country: country,
                country_id: country.id,
                price: price.toFixed(2),
            }
        });
        this.productCategories = res.body.categories.map((category) => {
            category.fields = category.fields.map(item => {
                item.allFields = [item.field];
                return item;
            });
            return category;
        });
        this.form.tags = res.body.tags;
        this.form.sizes = res.body.sizes;
        this.loadingResource = false;
    },
    (res) => {
        this.loadingResource = false;
        this.dialogVisible = false;
        this.$message.error(parseError(res)[0])
    }
  )
},

_isNew() {
    this.model.prices = this.countries.map((country) => {
        return {
            country: country,
            country_id: country.id,
            price: 0,
        }
    });

    this.model.export_factors = this.countries.map((country) => {
        return {
            country: country,
            country_id: country.id,
            fi: 0,
            margin: 0
        }
    });
    this.productCategories = [];
}

可能会发生什么情况？

过滤器函数内部的比较可能有问题。在比较两个id时，您可以将id解析为整数，如下所示。我只是在纠正你的_格式模型

_formatModel(model) {
this.productCategories = [];

this.loadingResource = true;
this.$http.post(this.baseUrl + '/show/' + model.id).then(
    (res) => {
        this.model.export_factors = this.countries.map((country) => {
        let result = res.body.export_factors.filter((item) => parseInt(item.country_id) === parseInt(country.id));
        let margin = 0;
        let fi = 0;

        if (result.length > 0) {
            margin = result[0].margin;
            fi = result[0].fi;
        }
        return {
            country: country,
            country_id: country.id,
            margin: margin,
            fi: fi,
        }
    });
    this.model.prices = this.countries.map((country) => {
        let result = res.body.prices.filter((item) => parseInt(item.country_id) === parseInt(country.id));
        let resultExport = res.body.export_factors.filter((item) => parseInt(item.country_id) === parseInt(country.id));
        let price = 0;

        if (result.length > 0) {
            price = (this.form.cif / resultExport[0].margin) / resultExport[0].fi;
        }
        return {
            country: country,
            country_id: country.id,
            price: price.toFixed(2),
        }
    });
    this.productCategories = res.body.categories.map((category) => {
        category.fields = category.fields.map(item => {
            item.allFields = [item.field];
            return item;
        });
        return category;
    });
    this.form.tags = res.body.tags;
    this.form.sizes = res.body.sizes;
    this.loadingResource = false;
},
(res) => {
    this.loadingResource = false;
    this.dialogVisible = false;
    this.$message.error(parseError(res)[0])
}

}，

您显示的响应是json响应。在转换为json格式之前，您能检查并显示响应吗？另外，我认为您显示的vuejs代码不完整。能否显示正确的vuejs代码，如初始化所有内容和所有内容？@KCP我显示的是关系带来的结果，我添加了另一个函数_formatModel我认为

内部过滤器后的
结果
值
\u formatModel
函数返回为空。你能在过滤器后面控制台并查找结果值吗？@KCP它在服务器上返回数组（0），但在本地项目上返回数据。如果你控制台res.body.export\u factors，是否有任何数据？
