EDIT: I know this question was closed because of the lack of information provided by recently I have encountered the issue that is exactly the same as described in the below code sample.
DbMigrationsConfiguration configuration = new Configuration();
DbMigrator dbMigrator = new DbMigrator(configuration);
dbMigrator.Update();
Unable to update database to match the current model because there are
pending changes and automatic migration is disabled. Either write the
pending model changes to a code-based migration or enable automatic
migration. Set DbMigrationsConfiguration.AutomaticMigrationsEnabled to
true to enable automatic migration.
EDIT (Continuation): This exception was caused by the call to Update method without parameters (I did reflected the method and found out that without providing the name of the target migration EF expects that you database and model are compatible with the Automated migrations.
Calling the Update("") solved my problem. Hope this edit will help someone.
The error exactly says you what you have to do:
configuration.AutomaticMigrationsEnabled = true;

I'm new to MVC web dev. As you know, Visual Studio generated local database to store the user credential, it has the UserProfile table. Shall I create a new database or use the auto generated local database and just create new tables there?
It will easier to use the existing database. And you don't even have a requirement to have a separate database.

In a different question I was suggested to use SSKeychain, and after searching the web it seems that SSKeychain is the preferred method for working with Keychain.
It is very hard to find code examples, and the ones there is just stores a string, which is a password.
How would you go about saving and retrieving a NSArray with SSKeychain, when you have several keys you wanna store in the keychain.
Thanks.
Have a look here: http://github.com/granoff/Lockbox. It's a project I built to store data securely in the keychain, which has the added advantage of surviving an app being deleted and re-installed.
This is drop in class. It just works.
EDIT: Now it just works. I think something about Xcode 4.5 got more strict than when I originally developed Lockbox. Thanks to a contribution from a forked version, it is again simply a "drop and go" solution.

Hi i have a requirement to simulate an error that states the iphone applicatio is unable to open the database and display values from it. i use sqllite. Please let me know how to simulate that error. I tried by locking the database file, changing the db file to readonly, but nothing happened... please let me know how to simulate the error...
Open the database with a separate connection, set exclusive locking mode, and make some change (you don't need to commit it).

I am currently working on a grails project. What I am trying to do now is to create an application that can store values of the user input without saving it on a database, and later access that stored values for further processes. Is there a way on how to realize this?
Please help. Thanks!
Update:
Sorry for the vague question..through further reading I have come to a solution that putting the user data input in a file is the solution to this query. It would be saved in a non-volatile storage, but not in the database perse..Thank you so much!
The options are almost endless.
You could just keep the data in memory, if it doesn't need to survive a restart.
Otherwise, you could write it to file, etc.
But it all comes down to pretty much the same thing as using a database.
Just curious - why don't you want to use a database?

I want to create an app where I have a table view and when I select a row where inside is written a name (at example "house") it give me in a textView the explanation of its meaning. What's the approach to do this app? I sould use a database as core data? but what's the way to take the text for every word? Can I use txt file or what? Can you help me?
If you want to store the data locally, I'd go either for core db, or xml file, depending on the kind of data. When you create a project in XCode with core data enabled, you can see how the crud is done.
