URL routing ASP Core MVC - asp.net

Question

I have 2 Models. Organization and Site. A org can have many sites but a site can only have 1 org. I have been able to successfully create a page that you can create an org with its primary site and all saves fine into the database.
What id like to do is have a page that shows all the sites for an organization. Id like the url to be something like ~/Organizations/6/Sites. and to see info on a specific site, the url should read ~/organizations/6/sites/2
How would i go about achieving this? Can anyone point me in the right direction. My understanding is that it would be done within the endpoints.MapControllerRoute section under the startup.cs file.
Below are the 2 models and the view action for the org and the viewsites action for the sites which currently both reside in the orgcontroller
public class Organization:BaseEntity
{
[Required]
[Display(Name = "Name")]
public string Name { get; set; }
[Display(Name = "Logo")]
public string Logo { get; set; }
[Required]
[Display(Name = "Type")]
public OrganizationType Type { get; set; }
[DataType(DataType.DateTime)]
public DateTime CreatedDate { get; set; }
[DataType(DataType.DateTime)]
public DateTime ModifiedDate { get; set; }
public int Demo { get; set; }
[Required]
public bool Active { get; set; }
public virtual ICollection<Contact> Contacts { get; set; }
public virtual ICollection<Site> Sites { get; set; }
}
public class Site : BaseEntity
{
[Required]
[Display(Name = "Name")]
public string Name { get; set; }
[Display(Name = "Address")]
public string FullAddress
{
get
{
return StreetNumber + " " + StreetAddress + " " + Suburb + " " + State + " " + PostCode + " " + Country;
}
}
[Required]
[Display(Name = "Street Number")]
public string StreetNumber { get; set; }
[Required]
[Display(Name = "Street Address")]
public string StreetAddress { get; set; }
[Required]
[DataType(DataType.PostalCode)]
[Display(Name = "Postcode")]
public string PostCode { get; set; }
[Required]
[Display(Name = "Suburb")]
public string Suburb { get; set; }
[Required]
[Display(Name = "State")]
public string State { get; set; }
[Required]
[Display(Name = "Country")]
public string Country { get; set; }
[Required]
[DataType(DataType.PhoneNumber)]
[Display(Name = "Phone Number")]
public string PhoneNumber { get; set; }
[DataType(DataType.DateTime)]
public DateTime CreatedDate { get; set; }
[DataType(DataType.DateTime)]
public DateTime ModifiedDate { get; set; }
[Required]
public bool IsPrimary { get; set; }
public int Demo { get; set; }
[Required]
public bool Active { get; set; }
[Display(Name = "Image")]
public string Image { get; set; }
public virtual Organization Organization { get; set; }
}
// GET: Organizations/View/5
public async Task<IActionResult> View(Guid? id)
{
if (id == null)
{
return NotFound();
}
var organization = _context.Organizations.Include("Sites").Include("Contacts").FirstOrDefault(x=> x.ID == id);
ViewBag.SiteCount = organization.Sites.Count;
ViewBag.ContactCount = organization.Contacts.Count;
if (organization == null)
{
return NotFound();
}
return View(organization);
}
// GET: Organizations/View/5
public async Task<IActionResult> ViewSites(Guid? id)
{
if (id == null)
{
return NotFound();
}
List<Site> sites = _context.Organizations.Include("Sites").Where(x=>x.ID == id).ToList().FirstOrDefault().Sites.ToList();
return View(sites);
}

Here is a working demo like below:
Model:
public class BaseEntity
{
public Guid Id { get; set; }
}
public class Organization : BaseEntity
{
[Required]
[Display(Name = "Name")]
public string Name { get; set; }
[Display(Name = "Logo")]
public string Logo { get; set; }
[DataType(DataType.DateTime)]
public DateTime CreatedDate { get; set; }
[DataType(DataType.DateTime)]
public DateTime ModifiedDate { get; set; }
public int Demo { get; set; }
[Required]
public bool Active { get; set; }
public virtual ICollection<Site> Sites { get; set; }
}
public class Site : BaseEntity
{
[Required]
[Display(Name = "Name")]
public string Name { get; set; }
[Display(Name = "Address")]
public string FullAddress
{
get
{
return StreetNumber + " " + StreetAddress + " " + Suburb + " " + State + " " + PostCode + " " + Country;
}
}
[Required]
[Display(Name = "Street Number")]
public string StreetNumber { get; set; }
[Required]
[Display(Name = "Street Address")]
public string StreetAddress { get; set; }
[Required]
[DataType(DataType.PostalCode)]
[Display(Name = "Postcode")]
public string PostCode { get; set; }
[Required]
[Display(Name = "Suburb")]
public string Suburb { get; set; }
[Required]
[Display(Name = "State")]
public string State { get; set; }
[Required]
[Display(Name = "Country")]
public string Country { get; set; }
[Required]
[DataType(DataType.PhoneNumber)]
[Display(Name = "Phone Number")]
public string PhoneNumber { get; set; }
[DataType(DataType.DateTime)]
public DateTime CreatedDate { get; set; }
[DataType(DataType.DateTime)]
public DateTime ModifiedDate { get; set; }
[Required]
public bool IsPrimary { get; set; }
public int Demo { get; set; }
[Required]
public bool Active { get; set; }
[Display(Name = "Image")]
public string Image { get; set; }
public virtual Organization Organization { get; set; }
}
Controller:
public class OrganizationsController : Controller
{
private readonly YourDbContext _context;
public OrganizationsController(YourDbContext context)
{
_context = context;
}
// GET: Organizations/Details/5
public async Task<IActionResult> Details(Guid? id,Guid siteId )
{
if (id == null)
{
return NotFound();
}
var organization = await _context.Organization.Include(o=>o.Sites)
.FirstOrDefaultAsync(m => m.Id == id);
var site = organization.Sites.Where(x => x.Id == siteId).FirstOrDefault();
return View(site);
}
}
Startup.cs:
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
//...
app.UseRouting();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}/{siteId?}");
});
}
Result:
Request url: https://localhost:portNumber/Organizations/Details/orgnizationid/siteid.
UPDATE:
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapControllerRoute(
name: "custom",
pattern: "Organizations/{id?}/{sites}/{siteId?}",
defaults: new { controller = "Organizations", action = "Details" });
});
Or a simple way is to use route attribute:
[Route("[controller]/{id}/sites/{siteId}")]
public async Task<IActionResult> Details(Guid id,Guid? siteId )

Answer 2

The way ive done it in the end is
Controller
// GET: Organizations/5
// GET: Organizations
[Route("[controller]/{id?}")]
public async Task<IActionResult> View(int? id)
{
if (id == 0)
{
return NotFound();
}
if (id == null)
{
return View("ViewAll",await _context.Organizations.Include("Sites").Include("Contacts").ToListAsync());
}
var organization = _context.Organizations.Include("Sites").Include("Contacts").FirstOrDefault(x=> x.ID == id);
if (organization == null)
{
return NotFound();
}
return View("View",organization);
}
// GET: Organizations/5/Sites/2
// GET: Organizations/5/Sites
// GET: Organizations/5
[Route("[controller]/{id}/sites/{siteId?}")]
public async Task<IActionResult> ViewSites(int ordId, int? siteId)
{
if (ordId == 0)
{
return NotFound();
}
if (siteId == 0)
{
List<Site> sites = _context.Organizations.Include("Sites").Where(x => x.ID == ordId).ToList().FirstOrDefault().Sites.ToList();
return View("ViewSites",sites);
}
Site site = _context.Organizations.Include("Sites").Where(x => x.ID == ordId).ToList().FirstOrDefault().Sites.ToList().Where(y=>y.ID == siteId).FirstOrDefault();
return View("ViewSite", site);
}
Startup.cs
app.UseEndpoints(endpoints =>
{
endpoints.MapControllerRoute(
name: "OrgSites",
pattern: "Organizations/{id}/{sites}/{siteId?}",
defaults: new { controller = "Organizations", action = "ViewSites" });
endpoints.MapControllerRoute(
name: "Orgs",
pattern: "Organizations/{id?}",
defaults: new { controller = "Organizations", action = "View" });
endpoints.MapControllerRoute(
name: "Orgs",
pattern: "Organizations",
defaults: new { controller = "Organizations", action = "View" });
endpoints.MapControllerRoute(
name: "default",
pattern: "{controller=Home}/{action=Index}/{id?}");
endpoints.MapRazorPages();
});
