I am an avid user of PetaPoco. Is there any way to tweak the Database.tt (for generation of POCO's) to specify a ResultColumn in a specific table?
TIA
Currently, the Database.tt states:
// Tweak Schema
tables["tablename"].Ignore = true; // To ignore a table
tables["tablename"].ClassName = "newname"; // To change the class name of a table
tables["tablename"]["columnname"].Ignore = true; // To ignore a column
tables["tablename"]["columnname"].PropertyName="newname"; // To change the property name of a column
tables["tablename"]["columnname"].PropertyType="bool"; // To change the property type of a column
I do not know how to change the template, other then these instructions (which work very well). I was hoping for a similar statement that could produce a POCO like:
[TableName("phoenix.view_medical_records")]
[ExplicitColumns]
public partial class view_medical_records
{
[Column] public string lastname { get; set; }
[Column] public string firstname { get; set; }
[Column] public string birthdate { get; set; }
[Column] public int? chart_number { get; set; }
[ResultColumn] public DateTime tservice { get; set; }
[Column] public string status { get; set; }
[ResultColumn] public DateTime tcompleted { get; set; }
[Column] public string procedure_description { get; set; }
[Column] public string description { get; set; }
[Column] public string provider { get; set; }
}
Note: the [ResultColumn] attribute being automatically supplied?!
Thanks.
As per my comment on the question, PetaPoco doesn't support result columns via the T4 generator files. However, a workaround would be to ignore the columns
tables["phoenix.view_medical_records"]["tservice"].Ignore = true;
tables["phoenix.view_medical_records"]["tcompleted"].Ignore = true;
And, supply partial classes for the generated one which supply the columns.
public partial Poco1
{
// Generated by PP
}
public partial Poco1
{
// Supplied by the developer (Must be in same namespace)
[ResultColumn] public DateTime tservice { get; set; }
[ResultColumn] public DateTime tcompleted { get; set; }
}

I want to perform auditing, by logging entity changes. I have an Audit class:
public class Audit
{
public int Id { get; set; }
public string UserId { get; set; }
public string Type { get; set; }
public string TableName { get; set; }
public DateTime DateTime { get; set; }
public string OldValues { get; set; }
public string NewValues { get; set; }
public string AffectedColumns { get; set; }
public string PrimaryKey { get; set; }
}
I've created AuditingInterceptor which I will add to multiple contexts. The Audits table is not accessible through these contexts.
internal class AuditingInterceptor : SaveChangesInterceptor
{
public override ValueTask<InterceptionResult<int>> SavingChangesAsync...
}
In order to save to the Audits table should I inject AuditContext that has access to Audits table or should I use another aproach?
I am working with the Podio api in C# and "Groupings" is missing from the View and ViewCreateUpdateRequest model.
When I use the sandbox call the result includes the groupings. So I'm thinking it is missing in the C# nuget package. Is there another way to access groupings for both Get View and Update View?
Sadly they are not maintaining the SDK for C#, but you can download their code from https://github.com/podio/podio-dotnet and update the code yourself.
That's what I did, I change the following
ItemId data type from Integer to Long
Added Groupings in View (Below is my View looks like)
public class View
{
[JsonProperty("view_id")]
public string ViewId { get; set; }
[JsonProperty("name")]
public string Name { get; set; }
[JsonProperty("created_on")]
public DateTime CreatedOn { get; set; }
[JsonProperty("sort_by")]
public string SortBy { get; set; }
[JsonProperty("sort_desc")]
public string SortDesc { get; set; }
[JsonProperty("filters")]
public JArray Filters { get; set; }
[JsonProperty("fields")]
public JObject Fields { get; set; }
[JsonProperty("groupings")]
public JObject Groupings { get; set; }
[JsonProperty("created_by")]
public ByLine CreatedBy { get; set; }
[JsonProperty("layout")]
public string Layout { get; set; }
[JsonProperty("type")]
public string Type { get; set; }
[JsonProperty("rights")]
public string[] Rights { get; set; }
[JsonProperty("filter_id")]
public string FilterId { get; set; }
[JsonProperty("items")]
public int Items { get; set; }
}

I have a project where I have a set of forms:
public class Form
{
public string Id { get; set; }
public string Name { get; set; }
public IList<string> FieldValueIds { get; set; }
public string UserId { get; set; } // the user who completed the form.
public string FormTemplateId { get; set; }
}
Which each "implement" a form template selected at creation of the form.
public class FormTemplate
{
public string Id { get; set; }
public string Name { get; set; }
public IList<string> FieldIds { get; set; }
}
Which defines which fields are present within the form. Each field
public class FormField
{
public string Id { get; set; }
public string Name { get; set; }
public string Caption { get; set; }
public ValueType DataType { get; set; } // Enum specifying the type of data this field accepts.
}
Stores information about the field such as a description and what type it is expecting. Each FormField can be present in multiple FormTemplates with the values for the form being stored as FieldValue objects related to the Form itself.
public class FieldValue
{
public string Id { get; set; }
public string FieldId { get; set; }
public string ValueAsJsonString { get; set; }
}
Other objects include the User Object:
public class User
{
public string Id { get; set; }
public string Username { get; set; }
public string GivenNames { get; set; }
public string Surname { get; set; }
}
I would like to be able to perform a query to find all Forms completed by a user with a specified name, or all Forms where a field with name X has value Y and so forth.
I have looked into usage of indexes as specified in the documentation Indexing related documents, however the implementation as presented in the documentation threw a NotSupportedException when I implemented the example as follows:
class FormTemplates_ByFieldAndName : AbstractIndexCreationTask<FormTemplate>
{
public class Result
{
public string Name { get; set; }
public IList<string> FieldNames { get; set; }
}
public FormTemplates_ByFieldAndName()
{
Map = FormTemplates => from FormTemplate in FormTemplates
select new
{
Name = FormTemplate.Name,
FieldNames = FormTemplate.FieldIds.Select(x => LoadDocument<FormField>(x).Name)
};
}
}
// in code:
IList<FormTemplate> TestResults = session.Query<FormTemplates_ByFieldAndName.Result, FormTemplates_ByFieldAndName>()
.Where(x => x.Name == "TemplateName" || x.FieldNames.Contains("FieldName"))
.OfType<FormTemplate>()
.ToList();
As best as I can tell this was implemented correctly, however I have seen a suggestion to replace the .Contains with a .Any implementation instead. In lieu of this I have been experimenting with a different approach by applying successive .Where arguments. Like so:
var pre = session.Query<FormTemplates_ByFieldAndName.Result, FormTemplates_ByFieldAndName>();
var pr2 = pre.Where(x => x.Name == "TypeTest25");
List<FormTemplate> TestResults = pr2
.Where(x => x.FieldNames.Any(a => a == "field25"))
.OfType<FormTemplate>()
.OrderByScoreDescending()
.ToList();
Modifying the system to perform in a more factory oriented approach by applying successive filters based on a supplied string in a pre-specified format.
Is this the way I should be going for this implementation and if not what should I be changing? In particular if I am to proceed with the Indexing option how would I apply this technique to the nested relationship between Forms and FormFields through FormTemplates.
You seems to be trying to do this in a way that is mostly relational, but you don't have to.
Instead of trying to have a set of independent documents that each has part of the data, just store it all in a single document.
public class Form
{
public string Id { get; set; }
public string Name { get; set; }
public IList<FieldValue> FieldValues { get; set; }
public string UserId { get; set; } // the user who completed the form.
public string FormTemplateId { get; set; }
}
public class FieldValue
{
public string Id { get; set; }
// can store the value directly!
//public string ValueAsJsonString { get; set; }
public object Value {get; set; }
}
This will generate documents that looks like this:
{
"Id": "forms/1234",
"Name": "Tom",
"FieldValues": [
{
"Id": "FromValues/SchoolDistrictName",
"Value": "ABi195"
}
],
"UserId": "users/tom",
"FormTemplateId": "FromTemplate/1234"
}
Which is a much more natural way to model things.
At that point, you can use RavenDB's ability to index dynamic data, see the docs here:

I have a table in SqlServerDatabase. Table name is User(Id,Name,Paswd) and Im using automapper in Mvc4. Now i want only specific fields or 2 fields from the table instead of whole table, using automapper.how to do??
basically if the 2 objects have the same fields as in the little example
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public string Paswd { get; set; }
}
public class UserDto
{
public int Id { get; set; }
public string Name { get; set; }
public string Paswd { get; set; }
}
You just have to ignore the field
Mapper.CreateMap<User, UserDto>()
.ForMember(o => o.Paswd, m => m.Ignore());
You can find a lot of usefull example and features here

We are using EF5, Code First approach to an MVC4 app that we're building. We are trying to update 1 property on an entity but keep getting errors. Here's what the class looks like which the context created:
public partial class Room
{
public Room()
{
this.Address = new HashSet<Address>();
}
public int RoomID { get; set; }
public Nullable<int> AddressID { get; set; }
public Nullable<int> ProductVersionID { get; set; }
public string PhoneNumber { get; set; }
public string AltPhone { get; set; }
public string RoomName { get; set; }
public string Description { get; set; }
public string Comments { get; set; }
public string Notes { get; set; }
public virtual ICollection<Address> Address { get; set; }
}
Here's our ViewModel for the view:
public class RoomDetailsViewModel
{
//public int RoomID { get; set; }
public string RoomName { get; set; }
public string PhoneNumber { get; set; }
public string AltPhone { get; set; }
public string Notes { get; set; }
public string StateCode { get; set; }
public string CountryName { get; set; }
public string ProductVersion { get; set; }
public int PVersionID { get; set; }
public List<SelectListItem> ProductVersions { get; set; }
public Room Room { get; set; }
}
Here's the Controller Action being called on "Save":
[HttpPost]
public virtual ActionResult UpdateRoom(RoomDetailsViewModel model)
{
var db = new DBContext();
bool b = ModelState.IsValid;
var rooms = db.Rooms;
var rm = rooms.Where(r => r.RoomID == model.Room.RoomID).Single();
//List<Address> address = db.Addresses.Where(a => a.AddressID == rm.AddressID).ToList<Address>();
rm.ProductVersionID = model.PVersionID;
//rm.Address = address;
db.Entry(rm).Property(r => r.ProductVersionID).IsModified = true;
//db.Entry(rm).State = System.Data.EntityState.Modified;
db.SaveChanges();
return View("RoomSaved", model);
}
All this view does is display data and allow the user to change the Product Version (from a SelectList), so, in the Room Entity, all we are updating is the ProductVersionID property, nothing else. We can get the data to display properly but when we click "save", we get this error:
An object of type 'System.Collections.Generic.List`1[[Models.Address,
Web.Mobile.TestSite, Version=1.0.0.0, Culture=neutral,
PublicKeyToken=null]]' cannot be set or removed from the Value
property of an EntityReference of type 'Models.Address'.
As you can see by the Controller Action, we've tried several different things but all seem to produce this error. I've tried to populate the model.Room.Address collection with an Address, without, but still get this error.
I read this StackOverflow article and this article as well but neither have solved my problem.
ANY help with this would be greatly appreciated!
After hours and hours of digging, turns out that EF did not import some of the PK's for my DB tables. What tipped me off to this was on the Room class, the PK RoomID did not have the [Key] attribute on it. I tried to reimport the table through the edmx but it never came through as a key (even though it's clearly marked PK in the DB). So, to get around it, I created a partial class of my DBContext and override the OnModelCreating event and included the key, like so:
public partial class DBContext
{
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Conventions.Remove<PluralizingTableNameConvention>();
modelBuilder.Entity<Models.Room>().HasEntitySetName("Rooms");
modelBuilder.Entity<Models.Room>().HasKey(r => r.RoomID);
}
}
Once this was done, the Action saved the record as hoped.
I hope this helps someone else!
