Question

I have a entity called Container in a Symfony application, which I have included in the schema.yml file:

Container:
  columns:
    id:    { type: integer, primary: true, autoincrement: true }
    name:  { type: string(127), notnull: true }

Strain:
  columns:
    id: { type: integer, primary: true, autoincrement: true }
    ...
    container_id: { type: integer }
    ...
  relations:
    Container:  { foreignAlias: Strains }

Then I have regenerated the models, forms and filters using the symfony doctrine:build --all-classes task.

Now when I try to use $strain->getContainer(), e.g. in a showSuccess action, it returns no object at all. I have double-checked that container_id has a reference to a record in container table.

Moreover, when I try to edit a Strain object and unlink the relationship with Container, the form is saved correctly, but the container_id column keeps the old value.

Do you know if Container is a reserved word or something like that in Symfony or Doctrine? What can be happening?

Thanks!

Answer 1

No, it isn’t a reserved word.
(In fact, I have a model in my project with a Container relation).

Have you tried setting the local property on Container relation to container_id?
