如何在sails.js中定义错误信息

这是我第一次使用风帆，它看起来不错，但我遇到了一个问题，是否有可能在sails模型validation中定义一个自定义的错误消息，因为它看起来像返回的错误信息是技术性的，而不是用户友好的。

谢谢

这是另一种select：

/** * Takes a Sails Model object (eg User) and a ValidationError object and translates it into a friendly * object for sending via JSON to client-side frameworks. * * To use add a new object on your model describing what validation errors should be translated: * * module.exports = { * attributes: { * name: { * type: 'string', * required: true * } * }, * * validation_messages: { * name: { * required: 'you have to specify a name or else' * } * } * }; * * Then in your controller you could write something like this: * * var validator = require('sails-validator-tool'); * * Mymodel.create(options).done(function(error, mymodel) { * if(error) { * if(error.ValidationError) { * error_object = validator(Mymodel, error.Validation); * res.send({result: false, errors: error_object}); * } * } * }); * * @param model {Object} An instance of a Sails.JS model object. * @param validationErrors {Object} A standard Sails.JS validation object. * * @returns {Object} An object with friendly validation error conversions. */ module.exports = function(model, validationError) { var validation_response = {}; var messages = model.validation_messages; validation_fields = Object.keys(messages); validation_fields.forEach(function(validation_field) { if(validationError[validation_field]) { var processField = validationError[validation_field]; //console.log(processField); processField.forEach(function(rule) { if(messages[validation_field][rule.rule]) { if(!(validation_response[validation_field] instanceof Array)) { validation_response[validation_field] = new Array(); } var newMessage={}; newMessage[rule.rule] = messages[validation_field][rule.rule]; validation_response[validation_field].push(newMessage); } }); } }); return validation_response; };

这是一个丑陋的修复：

创build一个名为my-validation-utils的文件夹。 在那里创build一个index.js文件。 并在其中提供以下内容：

 var user = { email:{ required:'Email Required', email:'Should be an email' }, name:{ required:'name required' } }; var product={ name:{ required:'Product name is required' } } var validationMessages = { user:user, product:product }; /** * This function expects the name of the model and error.validationError * and puts the user defined messages in error.validationError */ module.exports = function(model,validationError){ var messages = validationMessages[model]; for(key in messages){ var element = messages[key]; if(validationError[key]){ for(i in validationError[key]){ var err = validationError[key][i]; err.message = element[err.rule]; } } } return validationError; }; 

现在在你的控制器中做这样的事情：

 User.create(user).done(function (error, user) { if (error) { if (error.ValidationError) { var validator = require('path/to/my-validation-utils'); var errors = validator('user',error.ValidationError);// puts the messages for model user //now errors contains the validationErrors with user defined messages } } else { //user is saved } });
