meteor - MDG ValidatedMethod 与 Aldeed Autoform : "_id is not allowed by the schema" error

Question

当尝试使用自动表单通过 ValidatedMethod 更新集合时，我收到错误“架构不允许_id”。

据我所知this example和 official docs我的架构不期望包含 _id 字段，并且我不期望从更新语句中更新 id，所以我不知道为什么会发生此错误。

如果我从使用经过验证的方法切换到直接写入集合(将模式附加到没有 id 的集合)，一切都会按预期工作，所以我假设问题出在我的在我的 ValidatedMethod 中进行验证。

知道我做错了什么吗？

模板:customer-edit.html

<template name="updateCustomerEdit">
    {{> quickForm
        collection="CustomerCompaniesGlobal"
        doc=someDoc
        id="updateCustomerEdit"
        type="method-update"
        meteormethod="CustomerCompanies.methods.update"
        singleMethodArgument=true
    }}
</template>

模板“代码隐藏”:customer-edit.js

Template.updateCustomerEdit.helpers({

    someDoc() {
        const customerId = () => FlowRouter.getParam('_id');
        const instance = Template.instance();

        instance.subscribe('CustomerCompany.get', customerId());

        const company = CustomerCompanies.findOne({_id: customerId()});
        return company;
    }
});

更新验证方法:

// The update method
update = new ValidatedMethod({

    // register the name
    name: 'CustomerCompanies.methods.update',

    // register a method for validation, what's going on here?
    validate: new SimpleSchema({}).validator(),

    // the actual database updating part validate has already been run at this point
    run( newCustomer) {
    console.log("method: update");
        return CustomerCompanies.update(newCustomer);
    }
});

架构:

Schemas = {};

Schemas.CustomerCompaniesSchema = new SimpleSchema({

    name: {
        type: String,
        max: 100,
        optional: false
    },

    email: {
        type: String,
        max: 100,
        regEx: SimpleSchema.RegEx.Email,
        optional: true
    },

    postcode: {
        type: String,
        max: 10,
        optional: true
    },

    createdAt: {
        type: Date,
        optional: false
    }
});

集合:

class customerCompanyCollection extends Mongo.Collection {};

// Make it available to the rest of the app
CustomerCompanies = new customerCompanyCollection("Companies");
CustomerCompaniesGlobal = CustomerCompanies;

// Deny all client-side updates since we will be using methods to manage this collection
CustomerCompanies.deny({
    insert() { return true; },
    update() { return true; },
    remove() { return true; }
});

// Define the expected Schema for data going into and coming out of the database
//CustomerCompanies.schema = Schemas.CustomerCompaniesSchema

// Bolt that schema onto the collection
CustomerCompanies.attachSchema(Schemas.CustomerCompaniesSchema);

我终于弄清楚了这件事的真相。问题是 autoform 传入一个复合对象，该对象表示要更改的记录的 id 以及数据的修饰符 ($set)，而不仅仅是数据本身。所以该对象的结构如下:

_id: '5TTbSkfzawwuHGLhy',
modifier:
{ 
  '$set':
    { name: 'Smiths Fabrication Ltd',
      email: '<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bcd5d2dad3fccfd1d5c8d4cfdaddde92dfd3d1" rel="noreferrer noopener nofollow">[email protected]</a>',
      postcode: 'OX10 4RT',
      createdAt: Wed Jan 27 2016 00:00:00 GMT+0000 (GMT Standard Time) 
    } 
} 

一旦我弄清楚了这一点，我就将更新方法更改为这个，然后一切都按预期工作:

// Autoform specific update method that knows how to unpack the single
// object we get from autoform.
update = new ValidatedMethod({

    // register the name
    name: 'CustomerCompanies.methods.updateAutoForm',

    // register a method for validation.
    validate(autoformArgs) {
        console.log(autoformArgs);
        // Need to tell the schema that we  are passing in a mongo modifier rather than just the data.
        Schemas.CustomerCompaniesSchema.validate(autoformArgs.modifier , {modifier: true});
    },

    // the actual database updating part
    // validate has already been run at this point
    run(autoformArgs)
    {
        return CustomerCompanies.update(autoformArgs._id, autoformArgs.modifier);
    }
});
