I have an MVC project setup, and I've brought the subsonic Active Record templates into my project, and they generated successfully and I can use the subsonic classes to access my database. However, how do I create a strongly typed view using the subsonic generated classes? When I select "add View" and I check the checkbox to create a strongly-typed view, none of the generated classes from subsonic for my data are available.
View 2 RepliesI'm working against a database that wasn't designed by me and in all the tables there is a CreatedBy field that is an int. Now when I generate against this db i get all kinds of errors because subsonic is expecting that field to be a varchar.I don't particularly want to go and rename the field in all of these tables so I was hoping there was a way to "alter" or change the internal convention (without getting into the source) in subsonic.Has anyone been able/done this in subsonic 3.0.4??EDIT: I'm using the active record model in subsonic 3

View 1 RepliesI'm creating a small forum for my CMS and I'm using subsonic 2.2 as my DAL.
I'm loading my theads like this:
DAL.ForumThread item = DAL.ForumThread.FetchByID(id);
In my database my ForumPosts table looks like this:
ForumPostID | ThreadID | Description | UserID | CreatedOn| etc
So now when I have my DAL.ForumThread item I can load the connected post collection by using:
item.ForumPosts();
This all works great, but the problem is that I'm using serverside paging and want to add some additional select parameters too like showing only active records.
Is this even possible when using SubSonic 2.2 ? The workaround I have now is just creating a new SubSonic.Query and select the posts by threadid and there I can set pageindex and pagesize without problems but I think this can be done easier?
I also would like to know if it makes any difference performance wise by just using item.ForumPosts() or starting a new query, I think the forumposts are already in the ForumThreads collection and don't require a new database call right?
i wanna use to subsonic 3.0.4 but i dont know, how can i start to generate class and use to new Template of T4. example: create new solution for generating to table's class and add to my project. ??
View 2 RepliesIn subsonic 2 we could do this:
public static void DeleteTable(SubSonic.TableSchema.Table table)
{
new Delete().From(table).Execute();
}
How can we do the same thing in v3? I can only seem to find documentation about using generics to target a specific table in the database...I want to be able to use it with a parameter as above.
Using a SubSonic (2.2) SqlQuery object, I am querying a view that contains distinct rows from another table. The results of the query, however, contain multiple rows for certain rows in the view. It appears to be because of a join on a temporary table in the query generated to achieve paging. How can I avoid this duplication of rows?
Bonus points: I have to use the view because SubSonic can't do .Paged() and .Distinct() at the same time. Why not?
I have an emergency request that I need to sort it out very quickly as I did not notice it early :(.
I have a dropdownlist, the contnet in the gridview (sqldatasource connection) changes based on the value the user slects, say I have play1, play2 from the dropdownlist, I would like to show column1, column2 and column3 with user selects play1; show column4, column5, and clomn6 when use selects play2; the datatable actually includes all 6 columns.
I understand that I need to use something like RowCreated event, and I need to set up condition based on the dropdownlist value, but I dont really know how to.
I have the following code but when i try and create a new IQuerable i get an error that the interface cannot be implemented, if i take away the new i get a not implemented exception, have had to jump back and work on some old ASP classic sites for past month and for the life of me i can not wake my brain up into C# mode. The code is to create a list of priceItems, but instead of a categoryID (int) i am going to be showing the name as string.
public ActionResult ViewPriceItems(int? page)
{
var crm = 0;
page = GetPage(page);
// try and create items2
IQueryable<ViewPriceItemsModel> items2 = new IQueryable<ViewPriceItemsModel>();
// the data to be paged,but unmodified
var olditems = PriceItem.All().OrderBy(x => x.PriceItemID);
foreach (var item in olditems)
{
// set category as the name not the ID for easier reading
items2.Concat(new [] {new ViewPriceItemsModel {ID = item.PriceItemID,
Name = item.PriceItem_Name,
Category = PriceCategory.SingleOrDefault(
x => x.PriceCategoryID == item.PriceItem_PriceCategory_ID).PriceCategory_Name,
Display = item.PriceItems_DisplayMethod}});
}
crm = olditems.Count() / MaxResultsPerPage;
ViewData["numtpages"] = crm;
ViewData["curtpage"] = page + 1;
// return a paged result set
return View(new PagedList<ViewPriceItemsModel>(items2, page ?? 0, MaxResultsPerPage));
}
