我正在尝试在 Opportunity 模块中创建一个字段验证，当用户尝试将提交阶段从“Upside”或“Commit”更改回“Funnel”时会引发错误。验证功能在record.js用户尝试保存已编辑的机会时运行。它将选定的提交阶段与保存在数据库中的提交阶段进行比较。如果选定的提交阶段是“漏斗”并且保存的提交阶段是“上行”或“提交”，则会引发验证错误。抛出验证错误时，应突出显示提交阶段字段，并应显示带有错误消息的弹出窗口。

中的验证代码record.js如下所示：

initialize: function (options) {
    this._super('initialize', [options]);
    app.error.errorName2Keys['check_commit_stages'] = 'ERROR_CHECK_COMMIT_STAGES';
    this.model.addValidationTask('check_commit_stages', _.bind(this._doValidateCommitStages, this));
},

_doValidateCommitStages: function(fields, errors, callback) {
    console.log('Validating commit stages in record.js');

    let CommitStageSelected = this.model.get('commit_stage_c');
    let OpportunityId = this.model.get('id');
    let OpportunityBean = app.data.createBean('Opportunities');
    OpportunityBean.set('id', OpportunityId);
    let CommitStageSaved = '';
    OpportunityBean.fetch({success: function(model, data){
            CommitStageSaved = OpportunityBean.get('commit_stage_c');
            console.log('selected commit stage: ' + CommitStageSelected);
            console.log('saved commit stage: ' + CommitStageSaved);

            let SavedStageUpsideOrCommit = 
            ("Upside" == CommitStageSaved || "Commit" == CommitStageSaved);

            if ("Funnel" == CommitStageSelected && SavedStageUpsideOrCommit) {
                errors['commit_stage_c'] = errors['commit_stage_c'] || {};
                errors['commit_stage_c'].check_commit_stages = true;

                app.alert.show('message-id', {
                    level: 'error',
                    messages: 'Commit Stage cannot be changed from Upside or from Commit to Funnel',
                    autoClose: false
                });
            }

            callback(null, fields, errors);
    }});
},

问题是在机会已经保存后会引发验证错误。我收到一个“成功”弹出窗口说“已保存”，然后我收到一个带有验证错误消息的“错误”弹出窗口。提交阶段字段不会突出显示。

我猜测验证任务运行时间太长，可能是由于OpportunityBean.fetch函数的原因，因此在验证任务有时间抛出错误之前保存了记录。有没有办法延迟保存或加快从 bean 获取数据的速度？或者，问题是否完全不同？

我认为您也可以尝试这种方法来完成您要完成的任务

({
extendsFrom: 'OpportunitiesRecordView',

initialize: function (options) {
    this._super('initialize', [options]);
    app.error.errorName2Keys['check_commit_stages'] = 'ERROR_CHECK_COMMIT_STAGES';
    this.model.addValidationTask('check_commit_stages', _.bind(this._doValidateCommitStages, this));
},

_doValidateCommitStages: function(fields, errors, callback) {
    console.log('Validating commit stages in record.js');

    let CommitStageSaved = this.model.getSynced('commit_stage_c');
    let CommitStageSelected = this.model.get('commit_stage_c');

    console.log('selected commit stage: ' + CommitStageSelected);
    console.log('saved commit stage: ' + CommitStageSaved);

    let SavedStageUpsideOrCommit = 
    ("Upside" == CommitStageSaved || "Commit" == CommitStageSaved);

    if ("Funnel" == CommitStageSelected && SavedStageUpsideOrCommit) {
        errors['commit_stage_c'] = errors['commit_stage_c'] || {};
        errors['commit_stage_c'].check_commit_stages = true;

        app.alert.show('message-id', {
            level: 'error',
            messages: 'Commit Stage cannot be changed from Upside or from Commit to Funnel',
            autoClose: false
        });
    }

    callback(null, fields, errors);
}, })

使用这种方法，您甚至不必获取 Opportunities bean 即可从数据库中获取保存的数据。

感谢所有受访者！唯一对我有用的是：

let changedFields = this.model.changedAttributes(this.model.getSynced());
let CommitStageSaved = changedFields.commit_stage_c;

当我在@Sheikh Rahat Ali 的回答中尝试这种方法时，我得到了 CommitStageSaved = undefined。当我尝试@Jay 的方法并将获取功能限制为仅commit_stage_c字段时，我遇到了同样的问题，即在验证运行之前保存记录。我在 Sugar 开发者论坛上对我的问题的回答中发现了该changedAttributes功能。
