3.0 Final - TRIAL, December 8th, 2010 Adapter, Mysql, Target Framework: LLBLGen Pro Runtime

Hi All, I want to auto generate methods which will return entities by using unique constraint. as follows by using custom class LLBLGenHelper: DetailEntity e = LLBLGenHelper.Detail.GetDetailEntityByUCEmail ( "email@gmail.com" );

which will either return the entity or null if not exists.

To start, I see in the file entityIncludeAdapter.template the following code, which I have copied and pasted directly without modification into my custom template:

<[Foreach UniqueConstraint]>
        /// <summary> Method which will construct a filter (predicate expression) for the unique constraint defined on the fields:
        /// <[Foreach UniqueConstraintEntityField Comma]><[EntityFieldName]> <[NextForeach]>.</summary>
        /// <returns>true if succeeded and the contents is read, false otherwise</returns>
        public IPredicateExpression ConstructFilterForUC<[Foreach UniqueConstraintEntityField]><[EntityFieldName]><[NextForeach]>()
        {
            IPredicateExpression filter = new PredicateExpression();
<[Foreach UniqueConstraintEntityField]>         filter.Add(new FieldCompareValuePredicate(this.Fields[(int)<[CurrentEntityName]>FieldIndex.<[EntityFieldName]>], null, ComparisonOperator.Equal));
<[NextForeach]>             return filter;
        }

When I copy + paste this into my custom template, the generated output does not seem to get generated correctly, the result is:

<[ForeachUniqueConstraint]>
        /// <summary> Method which will construct a filter (predicate expression) for the unique constraint defined on the fields:
        ///  .</summary>
        /// <returns>true if succeeded and the contents is read, false otherwise</returns>
        public IPredicateExpression ConstructFilterForUC()
        {
            IPredicateExpression filter = new PredicateExpression();
            filter.Add(new FieldCompareValuePredicate(this.Fields[(int)DetailFieldIndex.], null, ComparisonOperator.Equal));
            return filter;
        }

Other code in my custom template is expanded fine, so the template configuration seems ok.

Any ideas ? Many thanks.

The task looks as follows:

            </parameters>
        </task>

I have tried changing emitType to "generic" but that did not seem to have any effect.

I think you are missing the last <[NextForeach]> statement to close the <[Foreach UniqueConstraint]> loop. Use allEntities in emitType.

Yes, thanks!
