Hi, I have three entities: Account, Project and Evaluation. An account can have multiple Projects, Projects can have multiple Evaluations. Now, I want to create a table (view only) to show an overview of the Evaluations with their related Project name (opdrachtnaam) and Account name (klantnaam). I have created a view for the Evaluation entity, which also contains the minimal view for Project and Account. I also created a screen fragment (evaluation-fragment.xml) which contains the table and loads the created Evaluation view. I can successfully load the Evaluation date field and Project name field to the table, but I can’t load the Acount name (klantnaam) in the first column table. How can I get this working?
Yes, that does the trick! One more question. I want this table to show all projects with their max evaluation_date (and an empty value if no evaluation has been done yet). How do I do that?
I’m sorry, but I’m a bit stuck here. I’ve created a KeyValueCollection as found in the topic you mentioned. Then I created a JPQL query to get the data, but I’m doing something wrong there. I’m seeing all possible opdrachtnaam/evaluation_date combinations. That’s not what I want. What I want to show in the table is:
all projects (opdrachtnaam) with their max(evalution_date)
if a project doesn’t have an evaluation yet: still list the project, but show an empty evaluation_date cell
Hopefully you are willing to help me a bit with the query. I can’t figure it out with the documentation only. Thanks in advance!
