Migrating to mormot 2

Is there a document available which lists which units different declarations have moved to?  For example TDocVariantData moved from SynCommons to mormot.core.variants etc?

I am trying to find the location for TDocVariantData.InitFromTypeInfo and also busy making a list of common mormot types that I use a lot and where they are now to make migrating existing projects easier.

Re: Migrating to mormot 2

What is the mormot 2 class for TSQLTableWritable called?

Maybe: unit mormot.orm.rest -> TOrmTableWritable

I did the conversion by taking the descriptive part of the name, in your case TSQLTableWritable => "TableWritable", and running a grep over all units. And as a second option, you can look for the compatibility definitions (example: type TSqlTable = TOrmTable). With this methods, you make fast progress.

With best regards

SQL is usually changed to Orm
I use the total commander to make searches in the files of Mormot2 source if something can not be found in the second attempt

Re: Migrating to mormot 2

Thanks TOrmTableWritable works perfectly.  I've been using windows grep for most of the day searching for the replacements.  Not sure how I missed this one.  Looks like my list is now starting to become useful.  I should be able to start migrating as soon as I find out about TDocVariantData.InitFromTypeInfo

InitArray* probably?

Re: Migrating to mormot 2

It doesnt look as if the InitArray* functions do the same

Re: Migrating to mormot 2

There's no direct equivalent inside TDocVariantData, you can write your own InitFromTypeInfo using same code

Something like TDocVariantData.InitJson(SaveJson(AValue, ATypeInfo));

Re: Migrating to mormot 2

It does exist something to initialize a TDocVariant from a dynamic array.

    /// initialize a variant instance to store some dynamic array content
    procedure InitArrayFrom(var aItems; ArrayInfo: PRttiInfo;
      aOptions: TDocVariantOptions; ItemsCount: PInteger = nil); overload;

Re: Migrating to mormot 2

If the new name for a class isn't obvious (e.g. remove the "SQL") I just search for a piece of text from the comments - the ones I've searched for so far have been unchanged.

Re: Migrating to mormot 2

Will the InitArrayFrom still provide the same structure / result when it is not an array?  I thought that would only apply to dynamic array types.

Re: Migrating to mormot 2

It is for dynamic array only, as you noticed.
