Hi, I have set up a simple app involving a parent-child relation. I followed the screencast "Using the Data Environment" part 1 and 2. I also took into account the following post and my app looks exactly the same (except for the names):
Got this from the following thread: http://www.mail-archive.com/dabo-users@leafe.com/msg14437.html I am not aware of a screencast named "Using Data Environment". So I can't directly comment. However, there is no way to use one bizobj and setup a parent child relationship. See below of example code of a parent child relationship. Note that the parent is the customer class and the child is the contacts class. A customer (maybe a company) can have many contacts - a one to many relationship. In the child (the contact class) there are two lines of the class that describes the relation so Dabo can maintain the relationship. self.LinkField = "fk_arcust" self.ParentLinkField ="pkid" So when you move the customer record pointer Dabo will retrieve the contacts data related to the customer. > #the contact table > class PubliccontactsBizobj(dabo.biz.dBizobj): > def afterInit(self): > self.DataSource = "public.contacts" > self.KeyField = "pkid" > self.addFrom("public.contacts") > self.addField("firstname") > self.addField("phone") > self.addField("pkid") > self.addField("lastname") > self.addField("title") > self.addField("custno") > self.addField("continent") > self.addField("email") > self.addField("cont_note") > self.addField("fk_arcust") > self.NonUpdateFields=["pkid"] > self.LinkField = "fk_arcust" > self.ParentLinkField ="pkid" > self.FillLinkFromParent = True > #the customer table > class PublicarcustBizobj(dabo.biz.dBizobj): > def afterInit(self): > self.DataSource = "public.arcustomer" > self.addFrom("public.arcustomer") > self.KeyField = "pkid" > self.addField("czip") > self.addField("city") > self.addField("pkid") > self.addField("state") > self.addField("company") > self.addField("address1") > self.addField("address2") > self.addField("country") > self.addField("custno") The problem is that the child is not behaving like it does in the screencast. It simply displays everything from child table in the grid. In the screencast only the related content from the child would be shown to correspond to the LinkField. This can be seen in the middle of the second screencast (part 2). Is there something I am missing or doing wrong? I have tested and played around with LinkField and ParentLinkField but it makes no difference at all. Exact same result every time. Any help would be appreciated.
