我花了很多时间,不知道如何使这个查询工作。我正在制作一个小时的操作类型模块,用户可以在其中选择如下内容:
Monday open from 8am to 11am closed from 11am to 1pm and open from 1pm to 5pm
这是完全动态的,用户可以选择他们想要打开和关闭的次数(动态生成的表单输入)
为此,我做了几节课(我不知道这是否是一种正确的方法,因为我已经使用 asp.net mvc、C# 和 EF 大约一周了。任何建议将不胜感激)
public class HoursOfOperation
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int Id { get; set; }
public IQueryable<CompanyHour> Monday { get; set; }
public IQueryable<CompanyHour> Tuesday { get; set; }
public IQueryable<CompanyHour> Wednesday { get; set; }
public IQueryable<CompanyHour> Thursday { get; set; }
public IQueryable<CompanyHour> Friday { get; set; }
public IQueryable<CompanyHour> Saturday { get; set; }
public IQueryable<CompanyHour> Sunday { get; set; }
//Navigation Property
public CompanyInformation Company { get; set; }
}
和
public class CompanyHour
{
public int id { get; set; }
public Status Status { get; set; }
public string From { get; set; }
public string To { get; set; }
}
public enum Status
{
Closed,
Open,
ByAppointmentsOnly
}
为了完整起见,这里是我的 companyInformation 类
public class CompanyInformation
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int id { get; set; }
//[Required]
[DisplayName("Company Name:")]
public string companyName { get; set; }
[DisplayName("Website Address:")]
[Url(ErrorMessage="The Website field is not a valid fully-qualified http, https, or ftp URL. (Example: http://www.website.com)")]
public string website { get; set; }
public string contactTitle { get; set; }
//[Required]
[DisplayName("Contact First Name:")]
public string contactFirstName { get; set; }
//[Required]
[DisplayName("Contact Last Name:")]
public string contactLastName { get; set; }
//[Required]
[Phone]
[DisplayName("Phone Number:")]
public string contactPhoneNumber { get; set; }
[DisplayName("Address Display?")]
public bool displayAddress { get; set; }
[DisplayName("Phone Number?")]
public bool displayPhoneNumber { get; set; }
//[Required]
[DisplayName("Address 1:")]
public string address1 { get; set; }
[DisplayName("Address 2:")]
public string address2 { get; set; }
//[Required]
[DisplayName("City:")]
public string city { get; set; }
//[Required]
[DisplayName("State:")]
public string state { get; set; }
//[Required]
[DisplayName("Zip/Postal Code:")]
public string zipCode { get; set; }
[DisplayName("Search Engine?")]
public bool allowSearchEngines { get; set; }
//navigation Properties
public virtual ICollection<UserProfile> CompanyUsers { get; set; }
public virtual ICollection<HoursOfOperation> CompanyHours { get; set; }
}
原因是,我在 hoursofoperation 类中对星期一、星期二进行了硬编码是为了让 mvc 轻松映射动态生成的字段(这部分有效!!!:))
现在我想查询数据库并创建一个小时的操作模型以发送回视图(在获取时),以便我可以带回保存的信息。但是,我不知道该怎么做。我正在发回一个 HoursOfOperation 课程。
我目前的查询:
var model = company.CompanyHours.Where(e => e.Company.id == company.id);
只返回一个只有 id(正确 id)的 HoursOfOperation 模型,所有 companyHours 实体都为空。
谁能帮我提出正确的查询?
