Security :: Creating Entity Like Classes For MySQL?
Mar 13, 2010
I am starting to build a website project for personal use to learn ASP.NET more in depth. I am wanting to use MySQL as a database since I have a friend thats a MySQL admin guy at his job. But I only have Web Developer Express 2010 and cant get the MySQL plugin to use the Entity Framework with MySQL. So I was wanting to create my own classes for each table in my database with properties related to each column so that I can use something like the following:
[Code]....
I just dont know how to go about doing this or what to search for in Google to find info on this or if this is even possible.

I am setting up my new project..We are using entity frame work 4.0..
Is there any way to generate all classes and interfaces as we create manually for 3-tier architecture...
Or do i need to generate manually...
Ex:
Itest.cs
Public Interface ITest
{
int testproperty {get;set:}
}
Test.cs
Public class Test: ITest
{
public int testproperty {get;set:}
}

I am using the ADO.NET Entity Framework for loading data from the database. The classes are directly mapped to database tables in the database. The problem is that these classes are not optimal for binding to the UI elements. As a result of this I have some custom entities which are populated at the service layer and returned. It is these custom entities (classes) to which I bind the UI elements. My questions on this are1. Is populating these entities at the service layer the most appropriate way to do this. I personally do not think so because if we introduce some additional UI elements which need different entities then I have to modify the service layer again.2. What is the best approach/pattern to get this done.

I am looking for a solid tutorial on using the Entity Framework with POCO (ie. not using the designer) using MySQL as the back-end. I am looking for something that is semi-in-depth covering stuff like attributes (like how to map a database table/field name to a class/field name that is different). Also I am looking for C#, not VB. Does anyone know of any such tutorials?

the problem is that it will insert a new record in a mysql table, I have already done the mapping of the mysql db and I have already done tests returning data and everything works. Now I read from a file, where there are queries written, I have them run me back and the result of true or false based on the final outcome of single query written to the file. Txt; I did this:
using (var w = new demotestEntities ())
(
foreach (var l listaqueri)
(
var p = we.CreateQuery <category> (l);
we.SaveChanges ();
result = true;
)
)
but it does not work, I sense that it returns no errors, but neither the result given written in the query. txt file is as follows: INSERT INTO category (id, name) VALUES (null, 'test2')

I am trying to create a relation between 2 of my model classes. I have separated my Model classes to be in their own project "Domain Model" and the application exists in the "WebUI" project.
I have 2 models.... SupportIssues and Users....
SupportIssues has a column UserID which is also a primary key in the Users table.
I want to create a relationship where one user can have many support issues.
I just can figure out how to do this?
Here is a snippet of my supportIssue.cs class:
[Code]....
How can i link UserID to my User.cs class?
Is it anything to do with the [Associate] tag?

I am setting up a routine whereby I have to copy the results of a MySQL stored procedure into a DataTable so that I can add fields to the end of the result.
Normally I would convert the Msql DateTime to something that I could more easily manipulate; however, the existing code that I have specifically addresses the MySql DateTime type in too many ways to easily change.
So I thought I could do something like this:
Code:
myDataColumn = new DataColumn("ETD_DT");
myDataColumn.DataType = System.Type.GetType("System.DateTime");
returnDataTable.Columns.Add(myDataColumn);
And substitute "MySqlData.Types.MySqlDateTime" for "SystemDateTime", but it fails with "Column Requires a Valid DataType".

I can't believe I'm having so much trouble finding this information. I'm endeavouring to learn about creating model classes with Linq to SQL. By default VS2010 wants to use SQL Express, but our organisation has several database servers for development so I'd rather use one of those. PLEASE can somebody tell me how I can configure VS2010 to do that, as all I get is 'A network-related or instance-specific error occurred while establishing a connection to SQL Server ... Verify that the instance name is correct'. Yeah, thanks Microsoft. Actually telling me how to verify the instance name would be a really good move here.

EDIT: This question is vague and will likely be of little use to anyone. I am awarding internet monies to the gentleman below whom "helped" me.Sorry that the title is a little vague. I am still new to asp mvc & EF. Here is my issue. I have a DB somewhat like this.
Employee
- ID
- Name
- Address
EmployeeJob
- EmployeeID
- JobID
- StartDate
JobTypes
- ID
- JobName
I want a create form that will show all the Employee fields as well as a list of JobTypes for the users to be able to select. Then I will post the results back to the controller and update the DB. I have started looking into custom viewmodels, but am still unsure of exactly how to put that together and get it to work.

I'm trying to customize correct displaying of dropdownlists so information shown in comboboxes is relevant to the kind of user logged on (maintaining referential integrity at data level)
e.g.: I have a user already logged on and depending on his profile I'd like to display to this user only the portion of the database that he would be allowed to see. That would mean that he might have acces to an specific subset of data, e.g.: businesstype = "3", loging level = "2", etc.
Is there a way of creating an Ado.Net Entity Data Model filtered on a Session variables as to maintain proper referential integrity at data level?

I am new to LINQ. when we drag tables we get a dbml file and designer file.
For example DataClasses1.dbml and DataClasses1.designer.cs.
Once we have them then we can start using our LINQ Queries.
In my company project I do not see this designer files and instead there are .tt files which were used as templates to greate ABC.generated.cs files. Is this same as designer class?

I am following the Nerd Dinner tutorial as I'm learning ASP.NET MVC, and I am currently on Step 3: Building the Model. One part of this section discusses how to integrate validation and business rule logic with the model classes. All this makes perfect sense. However, in the case of this source code, the author only validates one class: Dinner.
What I am wondering is, say I have multiple classes that need validation (Dinner, Guest, etc). It doesn't seem smart to me to repeatedly write these two methods in the partial class:
[code]....
This doesn't "feel" right, but I wanted to check with SO to get opinions of individuals smarter than me on this. I also tested it out, and it seems that the partial keyword on the OnValidate method is causing problems (understandably so). This doesn't seem possible to fix (but I could very well be wrong).

I don't know if this has to do with how FindControl works or how scope works. But my base class is having a hard time seeing the fields of child classes. Currently I'm planning have the derived class set a property in the base class, but there are a lot of derived classes, so that isn't a very attractive solution.
