我正在尝试为开发和测试创建postgres数据库.
我正在使用...
的Gemfile ...
gem 'pg'
database.yml的
default: &default
adapter: postgresql
encoding: unicode
pool: 5
development:
<<: *default
database: myapp_development
username: username
password:
test:
<<: *default
database: myapp_test
rake db:create:all 回报
PG::InsufficientPrivilege: ERROR: permission denied to create database
: CREATE DATABASE "myapp_development" ENCODING = 'unicode'
.... (lots of tracing)
Couldn't create database for {"adapter"=>"postgresql", "encoding"=>"unicode", "pool"=>5, "database"=>"myapp_development", "username"=>"username", "password"=>nil}
myapp_test already exists
怎么了？
编辑
我只是尝试将database.yml中的用户名更改为我在Mac上使用的用户名.有效.它还告诉我,不仅maybe_test' already exists, but it also just told …
我这里有一个简单的问题.我有一个带有created_at的实例变量.我将如何将其转换为 Month, day, year ~ September, 13, 1987
当我试着= @ example.created_at在我看来它给了我 1987-09-13
奇怪的是,当我在控制台中执行此方法时,我得到了 Sun, 13 Sep 1987
我有一个带有链接的导航栏。“品牌”链接有效，但没有任何ul作用。我已经阅读了有关e.preventDefault();问题的知识$('ul.nav > li').click(function (e) {。我还阅读了与之相关的文章z-index。我没有发现任何这种情况（除非我找不到嵌入在js应用程序加载的文件中并且不在我的Assets文件夹中的文件）。
是什么原因造成的？
我不确定它是否在css或js文件中。另外，切换功能还不错，它只是活动链接。

零件控制器.rb …
我正在尝试使用 Entity Framework Core UseInMemoryDatabase 编写测试，因此我的设置如下所示：
[SetUp]
public void Setup()
{
this.ContextOptions = new DbContextOptionsBuilder<GeneralContext>()
.UseInMemoryDatabase(databaseName: "DiagAc2Tests")
.Options;
}
我不知道是否需要，但上下文如下：
public class GeneralContext : DbContext
{
public DbSet<Entities.Application> Applications { get; set; }
public GeneralContext() { }
public GeneralContext(DbContextOptions<GeneralContext> options) : base(options) { }
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
var config = new DatabaseConfiguration();
optionsBuilder.UseNpgsql(config.GetConnectionString());
}
}
我在整个应用程序中使用此上下文并且它有效，所以我的测试如下所示：
public async Task CreateApplicationByService()
{
Mock<DTO.IApplication> mock = new Mock<DTO.IApplication>();
mock.SetupProperty(f => f.Name, "Application");
mock.SetupProperty(f => f.ProjectId, 666);
mock.SetupProperty(f => f.ConfigFilePath, …我在一个区域托管了一个 API 控制器。但是，路由似乎不起作用，因为我的 ajax 调用在尝试点击控制器操作时不断返回 404。控制器构造函数中的断点永远不会被击中。

public class WorldApiController : ControllerBase
