小编use*_*867的帖子

actix-web我正在尝试通过将 Rust 与和 一起使用来学习 Rust diesel。

当我尝试使用板条箱名称导入/使用架构时，它仅在文件中有效example.rs，但在post.rs文件中无效。这两个文件都嵌套在它们自己的文件夹中，我使用的命令如下：

use web_project_core::schema::posts;

当我使用另一个命令时，它可以在以下命令中工作，post.rs但不能在以下命令中工作example.rs：

use super::super::schema::posts;

我缺少什么？

// Cargo.toml
[lib]
name = "web_project_core"
path = "src/lib.rs"

[[bin]]
name = "main"
path = "src/main.rs"

// main.rs

use actix_web::{App, HttpServer};

mod handlers;

// lib.rs
#[macro_use]
extern crate diesel;
extern crate dotenv;

use diesel::prelude::*;
use diesel::pg::PgConnection;
use dotenv::dotenv;
use std::env;

pub mod schema;
pub mod modelz;

// post.rs

use serde::{Serialize, Deserialize};
use nanoid::generate;

use super::super::schema::posts;        // <-- …

我是Spring和Maven的新手。我正在尝试运行一个简单应用程序的jar，但收到以下错误：

java -jar target/gs-rest-service-0.0.1-SNAPSHOT.jar

这是pom.xml：

这是需要SpringApplication的主要类：

package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication …

这是来自karma.conf.js文件:

module.exports = function (config) {
  config.set({
      frameworks: ['mocha', 'chai'],
      files: [
        'bower_components/angular/angular.js',
        'bower_components/angular-mocks/angular-mocks.js',
        'public/ng-app/module.js',
        'public/ng-app/**/*.js',
        'test/ng/**/*.spec.js'
      ],
  ...

我试图使用beforeEach函数注入这样:

describe('my.test', function () {
  beforeEach(module('app'));

  var MyService;
  beforeEach(inject(function (_MyService_) {
    MyService = _MyService_;
  }));

  describe('#send', function () {
    it('exists', function () {
      expect(MyService.save).to.exist;
    });
  });

});

但是beforeEach(inject(function(...)...);当我尝试运行测试时,部分代码会导致此错误:

PhantomJS 1.9.8 (Windows 8 0.0.0) my.test "before each" hook: workFn for "exists" FAILED
        Error: [$injector:modulerr] Failed to instantiate module ng due to:
        TypeError: 'undefined' is not an object (evaluating 'Function.prototype.bind.apply')

我无法弄清楚问题是什么.有人有什么想法吗？谢谢.

我正在使用bcrypt-nodejs在预保存函数中散列密码.我无法弄清楚为什么我继续在bcrypt.hash的回调函数中收到错误'[TypeError:undefined is not a function]'.

var mongoose = require('mongoose'),
    validate = require('mongoose-validate'),
    bcrypt   = require('bcrypt-nodejs'),
    SALT_WORK_FACTOR = 10,
    REQUIRED_PASSWORD_LENGTH = 8;

function validateStringLength (value) {
    return value && value.length >= REQUIRED_PASSWORD_LENGTH;
}

var schema = mongoose.Schema({
    email: {type: String,
            required: true,
            unique: true,
            validate: [validate.email, 'is not a valid email address']
    },
    passHash: {type: String,
                required: true,
                validate: [validateStringLength, 'The password must be of min ' + REQUIRED_PASSWORD_LENGTH + ' characters length.']}
});
