The validation is fired when you call Project(), and since the
"required=True" attributes aren't yet present.
Try replacing:
proj = Project()
proj.ProjectId = self.request.get("txtProjectId")
proj.ProjectName = self.request.get("txtProjectName")
with:
proj = Project(ProjectId=self.request.get("txtProjectId"),
ProjectName =
self.request.get("txtProjectName"))
