Symfony have updated its ORM to doctrine and me too have update myself to new ORM . I was able to follow the jobeet tutorial

- wrote yml schema
- generated the model
- generated sql and successfully completed the project .

When i tried to customize the schema.yml by updating the schema , deleting and adding new tables . But after building the model and sql i found that along with new tables old ones were also generated  . Tried the same even after clearing the cache but no use . I couldn’t find a fix for the problem on net . After wasting hours on system i found a fix for it and here is it .

Fix :

Goto :  project_root\lib\model\doctrine – you can find some class files and a folder named base , delete all class files in doctrine and base directory . and try building the model and sql after clearing the cache .

You have fixed the error .

Hope the post helped you !
