I'm pretty new to MVC. I've built an EDMX, successfully created the models and am now trying to go through scaffolding to build a controller. The first thing I notice is that in the Model Class dropdown, I have duplicates:
Now, "BillysRentals2" is the name of the project. I don't know where those extras are coming from or where these "Model classes" are stored. It's true I've had to re-do the adding of the ADO.NET Entity thing several times, but even after I completely delete the EDMX and all its contents, some of those model classes still remain, so which are the real ones and where are the others hiding? It's confusing when you create "Model" and you're seeing "Model1" and stuff popping up.
But the second problem is that once I select a class, and press OK, I get this beautiful gem:
And yes, I tried removing the EDMX completely, doing a Re-build, removing and re-adding connections, Rebuilding again, and I'm still getting that message. What's wrong? I'm sure the fact that I'm getting multiple entries above means that there are bits and pieces of my previous efforts lying around someplace that are confusing MVC (not that it's hard to do) but how do I find them and get rid of them to start over?
And P.S. what is the difference anyway between a model class and a data context class?
I had several metadata files leftover from the last time, which had field names that I didn't import this time around.
My CoreData Worked before when I had an entity with one attribute called test, I tried to add a new attribute in the data model and I also defined it in my data.swift file but when I launch the application, it crashes on the loading screen every time, what am I not doing right? I can provide my code as needed.
When you run the application and then change the CoreDataModel, the next time you run the application it will give you an error indicating that the data model used has changed. To fix this, you can either remove the old version from the simulator (or device) and run the app again, or you can create a new CoreData version.
If just testing before the app has been released, deleting and running the app again works fine...
I have created a table on my app. On the next build I am adding some more column and changing the name of one column.
Because the table is already created it will not create the table again, hence the changes are also not get reflected.
How to deal with this problem? please help me..
I have an existing iPad application to which I've just added core data versioning. I've been through the documentation and followed the steps detailed. Now after choosing my new model as the current versioned model and trying to run it on my dev device from xCode I get the following error:
2012-03-28 07:35:42.137 DocsOnTap[2603:707] CoreData: error: (1) I/O error for database at /var/mobile/Applications/06EECF01-3598-4513-8A3A-BE4FD49EEBF6/Documents/.DocsOnTap.sqlite.migrationdestination_41b5a6b5c6e848c462a8480cd24caef3. SQLite error code:1, 'table Z_2TAG already exists'
The only change that I made to my model was to add in a single new entity. I have a table named Tag in my model - that appears to be what the error is referring to.
If I revert my current versioned model back to the previous model version then I can run my app on my dev device from Xcode without error.
I have read that there can be problems trying to use core data migration on dev devices. However I just want to test the process to be sure that when we update our app in the Appstore the migration works as expected for our customers.
In my case the same error appeared due to Renaming ID which was set in the Data Model inspector for the Entity. After I removed the Renaming ID the problem'd gone.
Well this was an obscure error. The entity that I was adding was named AppKeys - this must be the name of an entity used internally by core data or SQL Lite. I went back to scratch and found that I could add and migrate other attributes and entities without any problems. However if I tried once again to add my entity named AppKeys then I got the same error saying that 'table Z_2TAG already exists'. So the resolution to my problem is to choose another entity name. It is a pity that this is not documented somewhere obvious - or that the error was not more helpful. Anyway hopefully this might just help someone else one day.
I am getting an error about incorrect html when I return from the Save view which means the displayed scheduler is not being refreshed to fix the last set of data. Having made a change or addition, it is displayed correctly if I close the website and open it again, so the update has been saved in the table. It is just the refreshing of the currennt view that I am having problems with. Does anybody have any suggestions as to where I might look?
As usual, this was my mistake. I had created a new project and copied the Save.aspx view from another project. The Inherits="System.Web.Mvc.ViewPage<RLSBCWebSite.Controllers.CalendarActionResponseModel>" still referred to the old project.
Make sure you create a new page in your project and copy just the contenets from old projects!
