MVC :: Using EF4 Complex Types / Properties In Repositories?

Jan 13, 2011

Are there advantages in creating complex types in EF4 Entities and then use the complex properties in the repositories; instead of creating the aggregates in the the repository themselves? I.e. If the customer repository consists of properties of 3 entities: customers, addresses, email would it make sense to create a complex type consisting of the address and email properties, and add them as a complex property of the customer entity then just call the customer entity and the complex property in the repository, rather than just creating the repository class and aggregate the entities in the repository.What are there advantages or disadvantages in doing this in a MVC3 application?

C# - Webservice Complex Types And Class Inheritance - Use The Properties Of The Base Class?

Mar 13, 2010

Using the following Webservice definition using aClientArgs as a complex type:

[System.Web.Script.Services.ScriptService]
public class Controller : System.Web.Services.WebService {
[WebMethod]
public void save_client(aClientArgs client)
{
// Save client data
}
}
Then defining aClientArgs as a sub-class:
public class aArgs
{
public string id = null;
public string name = null;
}
public class aClientArgs : aArgs
{
public string address = null;
public string website = null;
}
Returns the following WSDL fragment for the save_client args:
<save_client xmlns="http://tempuri.org/">
<client>
<address>string</address>
<website>string</website>
</client>
</save_client>
When I'm expecting the following:
<save_client xmlns="http://tempuri.org/">
<client>
<id>string</id>
<name>string</name>
<address>string</address>
<website>string</website>
</client>
</save_client>

So it appears that the .NET WebService is not treating inherited properties as arguments/variables for purposes of a web service. How do I get .NET to also use the properties of the base class?

How To Send Complex Types To MVC2 Controller Via Jquery (Ajax )

Feb 22, 2011

I am posting a Jquery Json serialized object to my controller but not all of the data is getting passed. One of the members is a complex type that is also Json serialized. This is the one that isn't getting through to the controller.

Here is the class I'm passing to my controller via Ajax post. Note the complex type, RoutingRuleModel.

SourceCodeModel.cs:

[code]....

Problem: SourceCodeModel contains correct values EXCEPT for it's complex member: RuleModel, which comes back as a RoutingRuleModel with default (null or 0's) values.

Binding View Model From A Form Post With Inner Complex Types?

Apr 15, 2010

[Code]....

What I want to achieve is the ID of the property: item.Item.ID to be bound to the ID from the (route)URL. However I can't get it to work. I tried using [Bind()] attribute.

I fixed it now using a hidden field in the form like so:

<%= Html.HiddenFor(model => model.Item.ID)%>

However this feels a bit icky. I'd like to know if there is a better cleaner way of doing this?

Architecture :: Class Design - Application Allows Admins To Add Types Such As Document Types?

Oct 12, 2010

I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.

When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.

MVC :: Are Repositories Automatically Disposed Of In C#?

Dec 6, 2010

Could someone explain what happens to the Repositories that are created when they are no longer needed? Are they automatically disposed of, or should we dispose of them manually?

Using EF4 as the DAL, to keep the program efficient I have been building repositories for the Model that abstract the data needed for specific views or actions. I have also used the Iinterface for the methods and call them in the Controller to pass them to the View. At some point the program needs to pass a behavior or request that requires the creation of a new repository and the process may repeat itself over and over again. What happens to the repositories that created for previous views, but are no longer needed? Should the dispose be written into each repository, or does garbage collection take care of this? How should this handled?

.net - Architecture With NHibernate And Repositories?

Apr 13, 2010

I've been reading up on MVC 2 and the recommended patterns, so far I've come to the conclusion (amongst much hair pulling and total confusion) that:

Model - Is just a basic data container Repository - Provides data access Service - Provides business logic and acts as an API to the Controller

The Controller talks to the Service, the Service talks to the Repository and Model. So for example, if I wanted to display a blog post page with its comments, I might do:

post = PostService.Get(id);
comments = PostService.GetComments(post); Or, would I do:

post = PostService.Get(id);
comments = post.Comments;

If so, where is this being set, from the repository? the problem there being its not lazy loaded.. that's not a huge problem but then say I wanted to list 10 posts with the first 2 comments for each, id have to load the posts then loop and load the comments which becomes messy.All of the example's use "InMemory" repository's for testing and say that including db stuff would be out of scope. But this leaves me with many blanks, so for a start can anyone comment on the above?

Traditional Repositories Vs Single UnitOfWork

Aug 17, 2010

I would like to start a debate on traditional repositories versus one built on the UnitOfWork pattern. In a traditional repository, we wrap inserts, updates and deletes in a transaction, but selects don't really need them. In addition, nhibernate configuration is typically done once per application due to BuildSessionFactory being rather expensive. We often have several repositories of this type (one per aggregate chain). We also need to have projected, ahead of time, exactly what kinds of queries we'll need in order to build the interfaces and concretes correctly. In a single UnitOfWork repository we have the ability to manage both the current session and transaction, perform several operations, and then commit any changes all at once. In such a repository we may opt to put our configuration in the constructor since (typically speaking) no more than one Action is called per request anyway, initializing it in the application doesn't seem like much of an overall gain in speed. I must admit, I'm very temped to use the UnitOfWork pattern, as the following code looks really nice to me:

Csharp Code:
using (IUnitOfWork worker = new UnitOfWork()){// session and transaction are now both set
// save changes to three itemsworker.SaveOrUpdate(item1);worker.SaveOrUpdate(item2);worker.SaveOrUpdate(item3);
// grab a fourth var item4 = worker.Criteria<Foo>().Add(Expression.Eq("title", title)).UniqueResult<Foo>();
// delete the fourthworker.Delete(item4);
// all pending operations are commited or rolled back as a single unit (if one fails, all are rolled back), and then disposed, along with the session}

My proposed UnitOfWork class is rather simple. It implements IDisposable where I use a try-catch-finally in Dispose() to attempt a tx.Commit(), doing a tx.Rollback on failure, and a cleaning everything up in the finally clause. It also exposes common things like SaveOrUpdate, Delete, GetAll, Get, and even a Critera<T>() for custom on-the-spot queries. So what are your thoughts on this? I'd really like to hear about your experience with this pattern.

Single Repository Or Multiple Repositories?

May 1, 2010

In a typical business application, a session is started and persisted across several pages. It is commited only when the transaction is complete. A good example of this is a tax preparation application. Once the session is started, it is persisted through session, cookies, or both. Nothing is written to file, or database, until the entire profile is complete and the refund/return is calculated. In such an ennvironment, is makes a great deal of sense to work with the structure imposed by domain driven design, and using a single repository to simple commit the session. However, there are times when this doesn't translate correctly, even when domain driven design is used.

An example of this is my forum project. While the entities themselves are good targets for domain driven design, I am not sure about the repositories. The basic structure is that a Category has many Forums, a Forum has many Threads, and a Thread has many posts. There are other things in there, but that's enough to describe what I want to get across. If a user has navigated to /Thread/Edit/42, and they have rights to edit it, all I am concerned about is fetching that record and displaying it. On postback, all I want is to be able to save it..................

C# - Are Repositories Useful Without Domain Driven Design?

Mar 9, 2011

Assuming my application did not warrant a full blown DDD setup, would Repositories still be useful? I like the way they shield from implementation details (such as use of Entity Framework) underneath. However Repositories tend to be tied to Aggregate Roots (the concept is still a holy grail to me) by definition.

I suppose the question could also be put as such: if I have a typical 3-tier application, with a business layer facade consisting of "logical grouping" classes based on functionality (rather than aggregate roots as in DDD) such as TradingManager and ContactsManager, would it make sense to also create "logical grouping" repositories. Or perhaps a Data Access Object, which I believe is like a Repository without the aggregate root requirement. Of course I will still have a Model (EF POCOs) that will be passed up and down between the layers.

Also, is what I just described would be considered as a Transaction Script approach? It's certainly not DDD, and not Active Record. I'm not even sure if Active Record exists with EF4 like it does with Nhibernate.

I am trying to understand how others structure n-layered applications when they do not follow DDD.

MVC :: Multiple Repositories And Save DB Function

May 3, 2010

I have a few repositories in my project. All repositories inherit from an abstract interface repository containing the public datacontext variable and a Save function for the entire DB.

In my controllers I want to make changes to the the db and in one of my functions I'm working with two different repositories. Calling the Save function on each of the repositories I'm using can cause a situation in which one of the calls to Save succeeds and and the other fails resulting in a need of rolling back the changes of the Save function that failed.

What is the best way to work against multiple repositories and access to the DB to avoid such a situation?

C# - .net Development Code Structure -Controllers, Services, Repositories & Contexts?

Dec 11, 2010

As a new developer I'm getting thoroughly confused by naming and structural conventions for developing c# code using best practice.I appreciate it's perhaps applicable to each domain I am developing for but I've seen the code of many different open source projects and there seems to be a common theme. The successful projects have well thought out structure for maintenance and extensibility.The terms context, service, repository and controllers are used often and I wondered if these are open to interpretation or is there a consensus or convention on what, where or how these get used.

In an e-commerce platform I've seen there are order services, order contexts, customer repositories and product controllers for example. What should they do based on these names? Does a controller do something different to a service? When should you use a context? Is there a convention for namespaces? It's mind boggling when you try and push from a spoon fed newbie developer and try to move on.What software/tools should I really be looking at to develop quality code? Unit Testing, Continous Integration, Resharper, Mocking tools, DOI Containers, nHibernate.

I'm not really aware of blogs/books that will help me push on from being a proficient web developer into someone who can develop extensible, quality and testable code. There are big gaps in authors assumptions. You are either a newbie or a software architect. I want to push from being a junior developer with a long term aim of being a software architect. I realise it's all about patterns and practices but where are the training materials? I work on my own so don't have the opportunity of learning from others.

MVC :: How To Organize More Complex Routes

Mar 12, 2011

I understand the basics of setting up routes, I am trying to get a handle on how to organize more complex routes. Does the Route name do anything? I havn't seen a place it's actually used. If I have the route: controller/action/id/paramA/paramB/paramC. ParamA-C could be defining multiple parameters so First/Last/Zip or Phone/Zip/Birthday. Is it common practice to name the additional parameters with a generic name like paramA vs trying to differentiate a separate route for each?

Lastly, if you have multiple sites/functional areas in 1 site, lets say the asp.net site, each area MVC, Ajax, Forums ect were all different functional areas. Is it best to create a different group of routes such as hard coding the controller like:

MVC/action/id
Ajax/action/id
Forums/action/id

or is there a better way? What I am running into is 1 piece of the site overriding the other route because of the number/type of parameters.

Patterns To Use When Building Complex Web UI?

Jun 24, 2010

I need to implement a wizardy, dynamic UI that uses complex validation of the style:

If A = 1, show controls B, C, D. B is required, C is not, and D is not required must be less than 30 if it is populated.

If A = 2, show controls B, D, E. B is not required, D is required but has no limits, and E is not required.

If B is not null, show controls B, D, E. B is not required, D is required but has no limits, and E is not required.

Historically, I have made my presentation layer as "dumb" as possible in that it is only responsible for capturing user input and binding it to the appropriate domain model. The domain model, in turn, contains the logic needed to validate it's state and that of any child objects, and then communicates any invalid state to the presentation layer via notifications. As such, this requirement for a highly "intelligent" UI represents a departure for me.

I think I have no choice but to construct 2 very similar class hierarchies:

one that will capture presentation business rules (i.e. what fields are visible) and control what renders in the View

one that will capture domain business rules (when field A = X, then field B should be not null and in the range of n to m) to disallow objects with an invalid state from being persisted


Sill I have far more questions than answers on my strategy moving forward. Is there a set of design patterns I can draw on to build such a dynamic UI? I do have the option of using ASP.NET MVC or WebForms, so whichever approach will produce cleaner, testable code is preferred.

Complex Filtering In Web Application?

Sep 18, 2010

I need to estimate (and probably build later on) complex filter in ASP.NET WebForms application. The filter has to be mostly based on ASP.NET AJAX or jQuery for high interactivity. The filter has to allow filtering data with complex logical conditions (and, or, braces) and several operators. A user has to be able to save the filter's query and use it (load it) later on (server logic). Moreover there is still discussion about in operator.

Application should provide some graphical filter builder. I want to have full control on set of operands (filtering fields) and operators. The component will be used for all filtering actions in application. My problem is only how to do the UI part - translation of builded "query structure" is not a problem.

Have you ever did something like that? Can you share some experience how to best and fastest build such component? Do I need to develop component or is there any existing one which has at least some of the functionality and can be extended to provide other functionality? Because I'm not very experienced with client side development, I don't know how complex task is developing such component from scratch.

Another possiblity is to define some meta query language and allow users to write the query to some query text box with support for building logical expressions. I have already checked available controls in DevExpress and Telerik toolkits:

DevExpress:

Pros: Really nice visualization, fast. We probably have DevExpress licences. Cons: Tightly coupled with DevExpress grid. Based on documentation no extensibility and no control over operands and operators. It uses operands provided as columns for grid - I need much more. Probably not possible to save and load filters.

Telerik:

Pros: Not coupled with grid, it looks like separate control. Cons: I didn't find documentation - I'm not sure about extensibility but the code looks like it uses some databind control as source of operands = problem. I don't like the visualization. Demo is really slow. We don't have Telerik licences.

MVC :: Creating A Complex Form With C#?

Feb 10, 2011

How can I create a form that creates or updates a complex type that takes a form like:[Code]....

I would like to either create two forms one for tblstudent and one for tbldata and tblStudata or create one form for all three and give the illusion of multiple pages. I came across an old Railscast that talks about virtual attributes and a helper called fields_for which helps you switch between model contexts in a single form. Is there a way of achieving this kind of functionality with C# MVC 2 or 3?

If this sort of thing is not possible how else might I be able to handle create/update scenarios without defining two actions amd voews for each table entity I need to work with or god forbid separate controllers?
