Get component template by Name through content delivery API

Question

On the content delivery side I have filtered my components using metadata query, and now I have a list of components that need to be displayed. To get from component to component presentation next step is to choose CT.

As CT Id's will be different across environments, I would like "not to hardcode" id, but instead find CT "by Name".

This is possible through OData

...odata.svc/Templates?$filter=PublicationId eq 5 and Title eq 'Top News'

so the question is, can it be done through API ?

Answer 1

After going through all possible API's, I got a solution to retrieve component template based on component template names.

Mainly you need to use ItemTitleCriteria to retrieving the component templates by names.

Thanks to @NickoliRoussakov for the clue given.

    using (ItemTypeCriteria mItemTypeCriteria = new ItemTypeCriteria(32))
    {
        using (ItemTitleCriteria mItemTitleCriteria = new ItemTitleCriteria("My Component Template"))
        {
            using (PublicationCriteria mPublicationCriteria = new PublicationCriteria(123))
            {
                AndCriteria mTitleCriteria = CriteriaFactory.And(mItemTypeCriteria, mItemTitleCriteria);
                AndCriteria mTemplateCriteria = CriteriaFactory.And(mTitleCriteria, mPublicationCriteria);
                Tridion.ContentDelivery.Meta.IItem[] result = new Query(mTemplateCriteria).ExecuteEntityQuery();

                if (result.Any())
                {
                    Tridion.ContentDelivery.Meta.IItem template = result.FirstOrDefault();
                    String templateTitle = template.Title;
                    String templateId = template.Id.ToString();
                }
            }
        }
    }

Note that above solution might have performance impact. Please test it throughly before using.

Better option would be, by maintaining Component Template ID's in a configuration file with all the required template id's according to the environment and retrieve the component presentations.
