问题
I am working on Sonata admin bundle in Symfony2.3.3. I have a parent table and a child table which has a foreign key. Right now I am showing the Add/Edit screen of parent table. Is it possible to show the child table foreign key also along with the Add/Edit screen of parent table? And when clicked it should go to the Add/Edit screen of child table. Please help me. I googled much and have been with this for quite sometime now only to not find a suitable answer. Thanks in advance.
