Symfony OneToMany Persistence using entity/collection field type

Question

My Problem: I cannot get an associated Entity to save using the entity field type or collection field type.

My Database Relations

Database Structure Description:

• I have a 'Usage' entity that has many 'telephone numbers' attached to it.
• Each 'telephone number' has one and only one region.

What I want to Achieve

• On my edit 'Usage' form I want to display a dropdown box for each 'telephone number' that the 'Usage' already has attached to it.

• Each dropdown box will list all the telephone numbers for that region, allowing the user to select a new telephone number

How I want to display my Usage Form

My Controller

• Usage Controller line 146 - 203

My Entities

• Usage Entity

• Telephone Entity

Form Type

• UsageType - form

Twig Template

• Usage Form Page line 80 -128

ViewTransformer

ObjectToArrayTransformer

My Problem: When I submit the form, nothing happens, the new telephone number I selected is not persisted.

Answer 1

I think your problem is that in your Usage Entity, you don't cascade the persist operation. You should try this :

@ORM\OneToMany(targetEntity="Telephone", mappedBy="usage", cascade={"persist"})

Hope this helps
