php - What kind of entities i should create in doctrine for this db structure -

i have 2 tables in db (topic, topic_content):

what kind of entities should create symfony2? think, should have in symfony structure (entities/topic.php, entities/topic_content.php) me please..

yes, create topic , topic content. , user entity (because user_id looks foreign key).

however, idea in symfony2 approach application model site instead of database site. quoting https://doctrine-orm.readthedocs.org/en/latest/tutorials/getting-started-database.html:

development workflows

when code first, start developing objects , map them onto database. when model first, modelling application using tools (for example uml) , generate database schema , php code model. when have database first, have database schema , generate corresponding php code it.

for database first, there generator derive objects based on schema:

• https://github.com/beberlei/doctrinecodegenerator

the recommended approach though have doctrine generate db schema entities.

quoting getting started - generating db schema

doctrine has command-line interface allows access schematool, component generates required tables work metadata.

it requires setup, explained in guide. once have that, tell doctrine generate or update schema, whenever object structure changes.
