I need help with a Symfony project

I am new to Symfony development and would like some help.

I'm doing relatively simple tasks (Adding a field to an entity - currently getting 'Entity 'MyFood\ProjectBundle\Entity\Project' has no field 'projecttoken'. You can therefore not call 'findOneByprojecttoken' on the entities' repository' )

So looking for someone to help me with initial tasks and probably ongoing tasks as they come up.

Thanks
