Especially if one has to maintain something like this monstrosity[^].
What do you get when you cross a joke with a rhetorical question?
The metaphorical solid rear-end expulsions have impacted the metaphorical motorized bladed rotating air movement mechanism.
Do questions with multiple question marks annoy you???

Alright, I have my login stuff sorted, and it's time to start adding models that actually serve the web site's purpose. I'm a complete EF virgin, having been able to successfully avoid using it until today. What is the best (or typical) approach to adding models? Should each model (or model set) get its own dbcontext?

God, no.
There are a few schools of though as to the appropriate use of DbContexts. The two that make the most sense to me are that you separate the models into domains and use a context per model domain, and the other is that you have a DbContext for each separate database. I prefer the latter, unless your object count bloats obscenely.
The important part is that the DbContext implements both the repository and UoW patterns, so design it as you would any repository and use it as a UoW.
The primary guidance that the Ef design team has always espoused is that only the first instance of a particular DbContext has much cost, after that the model has been generated and any further instances are cheap.
I hope that helps.

I only have one database. Would it make sense to use the AppDbContext (derived from IdentityDbContext) that already exists?

No, I would quantify that as an object domain issue; Authentication and Authorization information should be separate from operational models.
|

Yep, I would leave the IdentityDbContext alone as it is used internally for Identity Framework. You should use your own DbContext for your database. I would recommend one dbcontext for one db.

Isn't it the DbSet that acts as the repository?

That's a fair question, and would certainly jive with some of the patterns I've seen built around EF.
My take on it is that a repository is not constrained to a single business object, especially in a relational setting where changes to object state can influence relations, so the DbContext is the repository. The functionally important part (to me) is that changes are tracked by the context, not the sets, and that multiple sets can have simultaneous changes tracked by the context.
This is entirely my personal opinion, I know, but from a design standpoint it makes a lot more sense to me.
Reading it again, I did make a mis-statement on the "implement UoW" part. "Supports UoW" would have been a much more appropriate statement, as it's entirely contingent on how you actually use the context.

Hi All.
I Create a website in this the login control connect to my SQL server (in the same machine) to verify user name and passs....
The connectionstring
<add name="RNOCDBConnecRNOCDB" connectionstring="Data Source=RNOCDB\;Initial Catalog=RnocDB;Integrated Security=True" providername="System.Data.SqlClient">
When I Run
http://localhost:4212/Default.aspx
It OK
But if I change the localhost by the server IP it has error:
Server Error in '/RNOC' Application
Login failed for user 'RNOC\RNOCDB$'.

Looks like you are not able to connect to your SQL server in hosting. Is the server from hosting company? Are you able to connect to it using SSMS?
|

|

Does your db sever require credentials?

I have a ASP.net page with an update panel triggered by a few imagebuttons (outside the updatepanel). All works OK.
Starting the page through a rewritemap.config however the imagebutton click is not executed, it becomes active but the click is not fired anymore.
I now do not know how to continu troubleshooting this problem, can anyone help me? Or provide a link where to look for more information?
Thanks in advance
Erik

Hello John,
The link provided the answer:
after a Form.Action = Request.RawUrl at page startup the problem was solved.
Thank you very much,

Let's say you have an individual user authentication scheme on a MVC5 app. Two part question:
0) When a user tries to browse directly to a controller action that is not specifically marked with the AllowAnonymous attribute, will the user automatically get redirected to the login page, or do I have to code it to do so?
1) Is the Authorize attribute involved? If so, where do I put it - on the controller or on the individual actions?
(The MVC5 app template does not provide an example of how this is done, or if it does, I haven't discovered it.)

Nevermind - I found the answer (and it is by using the Authorize attribute.

You don't have to do anything. When a controller or action is decorated with [Authorize] attribute then the ASP.NET automatically redirects the user to login page if the user is not already logged in.
1) Is the Authorize attribute involved? If so, where do I put it - on the controller or on the individual actions?
If your all actions in a controller to be authorized then it makes sense to put the [Authorize] attribute at controller level. If you have to leave at least of one of actions to be [AllowAnonymous] then obviously you have no option other than doing it at action level.
Hope this makes sense

i am familiar with form authentication. so please point out some difference between form authentication and claim authentication.
why people use claim authentication instead of form auth ?
in case of form auth a auth cookie is saved in client pc which pass to server for next subsequent request and check at server side which ensure user is authenticated or not.
so in case of claim authentication what kind of into is stored at client pc ?
please share the knowledge in detail and if any good write up exist on it then please redirect me there. thanks
