Ignore() is ignored by FluentMapping about npoco

[CaspianCanuck]

Looking deeper in the NPoco code I can see that it has something to do with TypeDefinition.ExplicitColumns being set to true in FluentMappingConfiguration.CreateMappings().

Then in the FluentMappingsPocoData constructor the code skips checking a property's IgnoreColumn flag is the ExplicitColumns is true.

I am having a hard time figuring out the logic behind this. As far as I am concerned, if a column is flagged as ignored then it should be truly ignored when SQL is built.

I got it! I need to pass false into the second optional parameter of Columns() in my InvoiceHeaderMap's constructor.

Adam, you might wanna clarify this fine point in your wiki to help other devs avoid a similar confusion.

Hey,
I'm trying to digest all of this.
Let me have a look and I'll get back to you. Could you summarize what you have found and what you think could be changed etc, so we have a plan of attach so to speak.
Cheers,
Adam

No need to change anything in the code itself, perhaps just make a point of explaining the importance of the explicitColumns argument in the wiki. Currently it's not even mentioned anywhere in your wiki example, so it's easy to overlook.

Thanks for your quick response!

2.2.45 has fixed the Ignore. It was not working when using the FluentMappings. It will always look at the ignore now.
Thanks!
