First off, thanks for all your efforts on this project. I have been evaluating several platforms for a project I am working on and Saltcorn is by far my favorite so far. One thing that I am struggling with is summing data across tables. For example, lets say that I have three tables. The first table contains employee information with a key field being the the employee number. Another table is a list of project which has a key field of project number. The third table is a table that contains time spent on projects. It contains three fields - the time spent, the employee number and the project number. What I would like to be able to do is create views that summarize in a list the projects and total accumulated time as well as another view with a list of employees and accumlated time. Is this possible and if so, could you share some instructions?
