I am using ActiveRecord and when I call Model.Save which calls
repositry.Update and then BuildUpdateQuery, it checks to see if item
is ActiveRecord and then return dirty columns. I don't have any dirty
columns. I assume this is because I haven't changed anything on my model but the problem is is that it continues to try and update the database with no columns set so you get UPDATE TABLE WHERE ID = 22
Definitely seems to be a bug in the ActiveRecord templates. You should submit an issue to the google code repository http://code.google.com/p/subsonicthree/issues/list. Check the bug isn't already listed first.

The PrePersistHook offers this method
Optional<ItemModel> execute(ItemModel item);
When implementing the PrePersistHook the changed model is passed to the method. The executing path already open a transaction and it seems that the item is already persisted, but the transaction is not committed, yet.
If I try to get the same Item again from the database with flexible search, it returns the already updated object.
The documentation => https://help.sap.com/viewer/bad9b0b66bac476f8a4a5c4a08e4ab6b/v2005/en-US/028a2af06880407cb4b1c0624693dadd.html
defines that one should not open transactions or create new threads.
But if it is not allowed, how is it possible to get the old version of the Model in a PrePersistHook to perform a validation or perform other check before the changes are persisted?
In our case, we want to create a new version of the OrderModel, but the persisted old version ever already have the old values. We see no opportunity to get the old version in a clean way.
Many standard prepersist hooks always fetch the item again from the database and return Option.empty() in the hook

I found a solution that works for me. I override the DefaultModelEntityService and read the data before it's updated.
I want to update Original Estimate field using Groovy in Scriptrunner that way changes will not appear in history.
I know that customfield.updatevalue() method does what i want, but it's for custom fields, not for TimeTracking field.
In documentation I saw a matching method
updateValue(FieldLayoutItem fieldLayoutItem, Issue issue, ModifiedValue modifiedValue, IssueChangeHolder issueChangeHolder)
, but there is 2 problems:
I dont know how to retrieve this field for an issue
And what modifiedValue should look like in code
I want to store information in some activities that are modified versions of activities imported from an existing database (ecoinvent).
I know we can add fields to activities created from scratch (example). (I guess this is because the structure of the database has not yet been defined...) but is there a way of adding it to activities of an already defined database without breaking it?
The way around I found is to add entries to the author dict, which I can easily access later on. e.g.
act['author']['scenario']='myscenario'
but I admit it is not a very elegant solution.
You can just add whatever data you want. Brightway is a (semi-)schemaless database for exactly this reason.
act['foo'] = 'bar'
act.save()
I'm developing an ASP.NET MVC 4.5 project using EF 6 Code First to an Existing Database. I would like to create some new tables with foreign key relationships to one of the tables in the dbcontext I've created. I've altered and added columns in that original table, creating several migrations. There is real data in that table.
I would prefer to create the new tables in the database, but don't see how EF would generate a model for me. I can code the model myself, but don't see any documentation about how I would add it to the context class generated by EF. And then the migrations would be out of whack.
So I'm thinking that the best thing to do would be to delete all the migrations, delete the context class and drop the migrations table. Then I could start from scratch with an initial migration. Am I missing some gotcha? Is there a better way?
FWIW to others facing this dilemma, I figured it out. First I got rid of all the migrations, following the 100+ up-voted answer here: Reset Entity-Framework Migrations
Second, I created new the tables and constraints I needed in the database.
Third, I created a new entity in my solution and generated model classes from the database. I changed calls from the old entity to the new entity.The generator overwrote the model for the original table, but since I have all the annotations in version control, it is trivial to paste them in.
If I need to, I can enable migrations again.
Hope this helps.
I have a data model that includes common columns like addedBy, editedby (user), addedDate, editedDate.
Is there a setting I can use in SubSonic 2.1 that will automatically update these fields appropriately instead of having to explicitly specify in every update?
Check out http://subsonicproject.com/setup/subsonic-conventions/. SubSonic uses a convention-based approach when it comes to audit columns. If you can change your column names to CreatedBy, ModifiedBy, CreatedOn, and ModifiedOn respectively, then they will be updated automatically. I don't think there's a way to change what those names can be without making changes to the SubSonic source code.
