I'm almost finished with a heavily-modified version of Paul Welter's templates. I don't want to release them until I do a little more testing, but I wrote about them on my blog so you can get an idea as to what's different. Feel free to check it out at http://demarzo.net/archive/2006/11/15/957.aspx and let me know what you think. When I publish the final templates (probably no later than tomorrow) I'll post a follow-up here. |

Hi there,
I have just downloaded and started using your template with Codesmith 4.0. There a couple of questions I came up with:
1. Did you include a generator for the mapping file? I couldn't find it and the generator kept asking for a mapping file. In the end I had to fire up Codesmith 3.2 and use Paul Welter's to generate a Mapping.config file first.
2. I haven't checked the rest of the code but have found at least one decrepancy between the examples in your blog and the generated code. The method Retrieve<T>.RetrieveFirst() has no parameterless overload. The closest one expects a (string whereClause). I have just passed a String.Empty for the meantime.
3. This is the only method I've tried so far: Dog dog = Retrieve<Dog>.RetrieveFirst(String.Empty). Unfortunately the solution failed during runtime right at the point of instantiating objectSpace. The error message was:
<quote>
Exception Wilson.ORMapper.ORMapperException was thrown in debuggee:
ORMapper: Type could not be located in any loaded assembly - BernerLine.Data.DataAccess.Dog
</quote>
I can't quite figure out what this means. Any ideas why this comes up?
Thanks,
Dany. |

- I didn't include Welter's generator file, though the one he had should work fine (barring compatibility issues with CodeSmith 4.0, but you can always use 3.2 with it).
- Thanks for the note -- I'll update my article to reflect this.
- It's tough to figure out without seeing your code, but some things I can suggest you check:
- Have you specified a different namespace for your Entities and Data Access layers?
- Did you create a project reference between both projects (this is not done automatically)?
- Do you have a Dog object in both namespaces?
Based on your example, the compiler seems to be looking for a Dog object in your Data Access namespace, not your Entity namespace. For example, the code this:
Dog dog = Retrieve<Dog>.RetrieveFirst(String.Empty)
... but the compiler sees this:
BernerLine.Data.DataAccess.Dog dog = Retrieve<BernerLine.Data.DataAccess.Dog>.RetrieveFirst(String.Empty)
The compiler should be looking for Dog in your entity namespace.
I hope that helps!

Hi Brian,
Thanks for the quick reply. I have done everything as you mentioned in your check list. There's only one Dog class and it's in the Entities namespace, which is in a separate project. I have no idea why it's looking for that class in the DataAccess namespace.
If you like I can put up the code on my SVN site for you to have a look? I can email you privately for login/password to the server.
I have also bastardised the generated code a little, by changing the default Provider.Sql2005 to Provider.MsSql when it finds "System.Data.SqlClient" - but I don't think that has anything to do with this problem....hopefully.....
Please let me know if you have some time to look at my code.
Cheers,
Dany. |

Problem found in your Mappings.config file --- the namespace and entity types must match your entities. In other words you have this:
<mappings version="4.2" defaultNamespace="BernerLine.Data.DataAccess">
<entity type="BernerLine.Data.DataAccess.Dog" table="Dog" keyMember="_id">
... where you should have this:
<mappings version="4.2" defaultNamespace="BernerLine.Data.Entities">
<entity type="BernerLine.Data..Entities">.Dog" table="Dog" keyMember="_id">
