symfony2-Create submission form generate data process

First, "one-to-many" relationship

Table Shop (i)

Table Comment (Multi)

Save with SHOP_ID

Second, we first to manually generate shop and comment relationship

First case (can be generated)

Controller in

Tables can be generated, corresponding relationships

Table Shop

Table: Comment

Because the shop table in the comments, in fact, there is no field in the shop table, here is just a sign, to take comments convenient. such as $shop->getcomments (), and it is convenient to add comment.

Second case (cannot be generated)

What if I change the addcomments function?

Table correspondence cannot be generated

Table: Shop

Table: Comment

Why is it?

Because the comment table ID is not associated with the shop (that is, the ID of the shop is not stored in the real comment table)

Scenario Three: (Table relationships can be generated)

Table: Shop

Table: Comment

Add shop directly to the comment

Well, actually there's a "many-to-many" relationship?

How do I automatically generate a one-to-multiple relationship when I submit a table?

Say it next time.

The above describes the symfony2-to create a submission form to generate data, including the content, I hope to be interested in PHP tutorial friends helpful.
