I have been using SubSonic 2 on several projects before but with the new SubSonic 3 I have implemented in 2 projects. However, my question has always been is if I can change the the output T4 template to generate a class file for each table instead of single ActiveRecord.cs file. I want to use it in a very large project and I can see where is not practical to have 80+ tables in a single file. I prefer to have separate class files.
Would I need to change SubSonic.Core?
If its not possible, please let me know.
Thanks
Why does it matter how many files there are if the code is entirely generated? What practical difference is there?
You can change the templates to output multiple files. No changes would be required to the SubSonic dll, just the T4 Templates.
However, I fail to see how it is worth even just the time to post the question here, much less the time required to actually make those changes.
There is a way to do this, if you rewrite the T4s to follow this example. However, I think there is an issue that may arise when you drop a table, the previously created .cs file for that table will not be removed. I think you would have to further edit the T4 to start by deleting all its previously generated files.

In Lotuscript you can manipulate design elements - create them, change them, rename them, etc.
Are you able to do the same thing for Xpages and custom controls design elements?
====================================================================
My question should have been clearer. What I want to accomplish is to copy an existing cc and give it a new name, programatically. The app will then close and reopen (or refresh or get rebuilt) so that the app can "see" the new cc. If I copy the cc it will only have one field on it. I will add custom code later. I could just create a new cc with no code in it, that would work too.
I am not familiar with the DXL exporter but I can research it. Using that can I just export the design of the cc to an XML file in a temp directory, use the transform to change the name, and then import the control?
I think the XPage or Custom Control design elements are probably under MISC_CODE or MISC_FORMAT design elements in a NoteCollection.
However, accessing that design element is the easy part. Doing a create / rename / change etc is a much bigger task.
Remember that the XPage or Custom Control XML file is only a starting point:
XPages and Custom Controls also have a .xsp.metadata file, as you'll see with source control.
Custom Controls will also have (and need) a .xsp-config file.
There are corresponding .java files for every XPage and Custom Control in the Local source folder. They're created by a builder based on parsing the XML. I don't think you'll be able to create those programmatically. I'm not sure of the impact of renaming them.
For Custom Controls, even if you can rename the .java file, it's referenced in the .java files of relevant XPages. Updating those is goiong to be a significant task.
The XPages runtime doesn't even use those .java files. Instead it uses the .class files in WebContent\WEB-INF (you need to use Project Explorer view and modify the filter to see those files). This is compiled byte code, so you won't be able to update the .class files for XPages containing renamed Custom Controls, as far as I know.
Even if you can rename the .class files, the XPages runtime almost certainly won't use them until either a Clean (which will overwrite anything you've done) or an HTTP restart. As far as I can tell they're cached.
Depending on your use cases, it's possible not all these points will be an issue, e.g. if you're modifying the XML files and building with headless designer.
I suspect this is why nothing was added to the NoteCollection object or a specific NotesXPage / NotesCustomControl API class added.
In Lotuscript you can manipulate design elements - create them, change them, rename them, etc.
This is only partially true. There is a LS API to create/alter views and outlines. Good luck with other design elements - although they're standard "notes", so you can access their items, in most cases you won't compile them and there will be some problems with signatures (real experience with TeamStudio CIAO).
Your question has two points of view - do you want to alter design elements in design process or alter running application?
To help a designer you can go the way of Eclipse extensions and enrich tools in IBM Designer to help developer. Something like TeamStudio Designer. In this case you need to look for source design elements, mentioned by Paul.
To enrich application you don't need to alter source design elements. IBM Designer transforms XML in source code to a Java code (JSF framework) - so you can generate your Java code from anything you wish. Take a look inside Local\xsp folder of NSF in Package explorer. You will find Java sources made from your XPages and Custom Controls. So if you don't need to work with design elements, go for Java components - they can be built on the fly.
And of course, there is always the option of DXL framework - so you can clone/alter design of the application through XML transformations. Good starting point: http://www-10.lotus.com/ldd/ddwiki.nsf/dx/ls-design-programming.htm
I ran into my first Core Data versioning problem - learn something every day!
Following instructions found here, I made a new version of the model, added the code for lightweight migration, and then went to set the active version…
Uhhh, where do you do that? The docs don't actually say, and other threads here talk about "click on the main file". WHAT "main file"?
The original xcdatamodel has no version number in it. Is that a problem? Is the Migration Manager still going to be able to figure this out?
All I did was add a field, this seems like a lot of work…
Core Data model files don't use version numbers. The files might include a number in their name, but that's for people to see, Core Data doesn't care about it. It uses entity hashes to compare models.
The "main file" is the .xcdatamodeld that contains all the versions (which have names ending in .xcdatamodel).
Select that then look in the file inspector pane on the right. It has a pop-up menu that you use to select the current version.
When generating my DAL files with SubSonic, I'd like the names of the files to be .gen.cs. The main reason for this is that the files are partial classes, and I would like to add some additional implementation details into another source file for the table called .cs. This is somewhat the standard pattern for generated source files , and I'm wondering if its possible with SubSonic? I'm using SubSonic 2.2.
I thought you might be able to do this by using a set of custom templates, but the CS_ClassTemplate.aspx (or VB_ClassTemplate.aspx) doesn't control the file name of the class.
I don't think this is possible.
As an alternative, you can do what I do. I have a "generated" directory, such as \database\generated and then I put my partial classes at \database\custom. As long as the namespaces of the files in the two different directories match (like .database or whatever), then it works fine. By using two different directories, it's easier to find your custom files without looking at the generated ones.
Hi I just downloaded subsonic 3.0 and I want to work with stored procedures. I don't know which template to choose: ActiveRecord or LinqTemplates. I don't really know the difference. I know that I don't want to deal with Linq code. I just want subsonic to generate classes based on tables and also their relationships (if possible) and generate code to interface with stored procedures.
I couldn't find a lot of info on the subsonicproject site. I don't know which template folder to drag into my project, and which _settings.tt file to change. Under the T4 templates, there are four folders: ActiveRecord, LinqTemplates, SubSonic.TemplatesVB, TemplateProviders. I don't know which one to deal with for my situation. Can somebody post step by step instructions please, or point me to a page that already does?
Thanks
I'm currently using the Activerecord template, wich generates a class with every stored procedure in the database. The settings.tt files depend on wich database you're working (SQL Server, SQLite, MySQL..) There is a straightforward instruction to configure the Activerecord templates: http://subsonicproject.com/docs/Using_ActiveRecord
Are there any restrictions on the names of tables, or issues with certain names when working with SubSonic?
I have table called 'Activity' and SubSonic doesn't seem to recognise it. When it was called 'Activities' it worked fine.
Basically I am wanting to go with singular table names as a convention (and the other conventions as detailed in the SubSonic Conventions blog post) and added fixPluralClassNames="false" to the web.config (because I have a table called 'Focus', which SubSonic kept naming 'Focu')
Generally, reserved words in C# are not allowed as table names. I'm not sure why Activity would be a problem though. The first thing to check when a table is not generated is that the table has a primary key.
One common problem that I ran into was it would not work if my tables begin with special characters or numbers. Changing that fixed it on my end. Apart from that I did not run into any other issues.
Clearing files in the Temporary ASP.NET Files folder (After closing Visual Studio), or changing the .abp file seems to be a valid fix to this.
