New Post: Suggestion needed for object level changes.

mehfuzh — Fri, 15 Jan 2010 07:59:29 GMT

As with current version, if we need a book object

public class Book

{

public string Name {get;set;}

public string MyBook {get;set;}

}

Here , i dont need the MyBook property to be included in my searh or being considered with Linqextender. Currently, the way is to mark it with [Ignore] attribute. But rather doing that how about making the implemention dependent on interface or "virual" proeprties. In that case if you dont need something then. just dont define it in your interface or dont mark as virual.

So, the Book becomes :

public Book : IBook

{

public string Name {get;set;}

public string MyBook {get;set;}

}

where IBook implements the "Name" property. So, "MyBook" wont be considered anyway. Or mark the property as "vrual" :

public Book : IBook

{

public virtual string Name {get;set;}

public string MyBook {get;set;}

}

Any issue you see ?

New Post: Does this Support Nested Object Graphs

Hi,

Can you please write here the LINQ query that you are looking for here. LinqExtender do supports nested object graph. But which is not impllement SQL ORM that comes with it. Its in the todo list.

AB_dreeve — Tue, 20 Oct 2009 21:04:34 GMT

Is there support for object graphs like this? Or can this only be used with simple graphs?

public class Order {
   public int Id {get;set;}
   public string Description {get;set;}
}

public class Customer {
   public int Id {get;set;}
   public string Name {get;set;}
   IEnumerable<Order> Orders {get;}
}

What license is this library released under? When I click the download links, I get offered a copy of the GPL to agree to before downloading, but the only license I can see in the downloaded source code itself is a waranty disclaimer (no GPL). My intention was to use the library as part of a commercial closed-source project, which will be impossible if the code is GPL-licensed.

First of all can you give me another username of yours at codeplex, unfortunate whenever I try to add in the contributor list I get an exception, don’t know why ? You can feel free to make changes that solve problem globally.

Hi Again Mehfuz

Sorry for being a little away of the project but I was attending some work issues different to this, so I found the cause of my predication issues, the reason is located on IQuery interfaces, it only implements any and count methods, but not the where that I need, please tell me if I need to expand this Interface to achieve this or you have a better idea on that, fixing this, I will have the time needed to be dedicated to help you achieving your new goal, if you still need my help off course, just let me know the details of your new idea if you have them, and I will separate some hours at my weekend to working on it by now, when I resolve my predicate issue I can give more time to work on it.

Thank you in advance.

Hi,

I have added you as a contributor to the project with this kmilovm username. If you get , latest bits, you will see that I have separated the SQL formatter from the main project as it should not be tied to the main project.

Now, the idea is that we can be able to add any attributes to the settings using the Fluent settings, that will make it as a generic project.

Extender.Settings.For(book=> book.id).WithAttribute(typeof(MyAttribte)).MarkAsUnique(false); that will make it unique but non identity.

Similarly,

Extender.Settings.For(book=> book.id). MarkAsUnique(false); that will make it unique but non identity.

Also, I have a plan to generate meta language like (OQL) instead of original sql from the formatter that will make it portable to different databases. That’s it for now, let me know, if you can help me on that.

Regards,

Mehfuz

Hi,

Now, the issue is Identity makes the attribute more database centric, remember LinqExtender is a generic product not a database tool , but yes , it is mostly used in database. Actually, I should remove the TSql stuff from LinqExtender.Core to LinqExtender.Providers , then we can modify the TSqlFormat provider the way we want.

You could have added just a property in unique attribute that will make it , non identity. Like IsAutoGenerated = true, then you can specify it either from attribute or Extender.Settings. Let me know what is the issue with predicate, I mean few codes.

My email : mehfuz@gmail.com

Mehfuz.

Hi Mehfuzh,

First than all I want to apologize for my mispelling of your name at last post, sorry for that!!! well about the modifications that I made were in the bucket attempting to work with Ignore attributes at all time but the sql process, in fact you could make several operations at bucket time with this fields at your own implementation of the provider and another objetcs but it will ignore them at CRUD time, another feature is the Identity attribute, marking a property with this attribute you will gain some database like functionality where the unique field is different than identity one.

Im still having issues with the predicates, can you give me a little help on that? Thanks in advance.

Hey,

Let me know the features.. I will take a look.. optionally.. I will set you up an account, which i forgot to do earlier. But please list down the features you have made, also add few test methods regarding it.

Hi again Mezfuzh,

I recently finished my own implementation of LINQEXTENDER, and has some new features that I would like to you to check, please tell me where I can send you an email with the code, Im currently correcting some troubles with the predicates at the objects collections, do you know if your version has this issues too? the issues are expecifically that I provide the predicate and the collection cannot make the query on itself and returns me the entire collection, any ideas?

TIA,

That's cool but original idea was to remove the dependency from any database related attrubutes as extender can be used in other projects like LinqToFlickr. May be you can do a TSqlFormater modification.. any let me know how it goes.. i will be adding you to the project as well. Is this your original codeplex id?

New Post: What if UniqueAttribute is not the identity one?

kmilovm — Thu, 16 Jul 2009 15:34:11 GMT

Ok, Im start the modifications to the extender I implement a new attribute marked as IsIdenity for making a difference on Unique and Identity fields on database, this works perfectly at inserting time on the datacontext, but when I modify some entities the bucket still recognize the IsNewlyAdded because the method to get this property value its getting all the unique and identity attributes on item, and if its new or modified always will have this atributtes set, how can I difference better when Im inserting or updating?

Thanks In Advance

Thank you for your sooner answer Mehfuzh.

I was reading the article that you describe me before I post, I think that I was not too specifical at the last post, Im currently implementing a vsaddin for emulating the behavior of linqtosql, but my entities are objects generated upon some queries on database, for example: I have a table that holds all the object information, another to get the attributes of this object and the last one with the relations of this attributes with the object itself and another objects like itself, so my addin shows graphically this objects and using CodeDOM I will build a dbml diagram with all the custom logic inside to get this objects works as linq, in this part is where your extender comes up, so my objects are dinamically generated using the database properties like nullable and primarykey, in the case of being primary keys my codedom marks this field as uniqueattribute, but getting into your code I could see that your mark as IsNewlyAdded the item when you submit the changes on the objectcontext based on the condition if the item has uniqueattributes, but if mark some attributes as unique, the extender assume that these fields are Identity and are not part of the insert operation, I see several things to do, but all of them implies modifying the core of the extender, and as I say on the first post I dont wanna do that because any time you drop a new version I will have to check if the new version impacts my modifying one, if you want for being more clear about my position, I will send the code to you if you want to see it by yourself.

Thanks in Advance

KMILO
