I suppose the answer is no but I am asking to be sure.
SensioGeneratorBundle contains a command to generate entities. Do you know if it can generate the mappings for a one2Many or Many2Many field? Is there any project that implements this?
The only example I found:
php app/console doctrine:generate:entity --entity=AcmeBlogBundle:Blog/Post --format=annotation --fields="title:string(255) body:text" --with-repository --no-interaction
Many thanks
I know this is old... but this could help some people.
Here is a Symfony3 bundle that can generate Doctrine 2 associations, including a one-to-many relationship:
https://github.com/Remg/GeneratorBundle
Associations
Handles all Doctrine2 association types (OneToOne, OneToMany, ManyToOne, ManyToMany).
Handles unidirectional and bidirectional associations.
AFAIK the answer is no. I have already asked a similar question and it seems that there is no free tool that can do that. But if you want to pay : http://www.orm-designer.com/
There is a workaround that makes the job perfectly, without any additional software or bundle to install.
You just have to edit the DatabaseDriver.php from doctrine like described here :
Symfony2 Doctrine2 - generate One-To-Many annotation from existing database by doctrine:mapping:import

I am running a Symfony 3.4 based web service using Doctrine to manage and persist the different data entities.
Now I am trying to implement a method which transfers older, abandoned user accounts to another database which acts as archive.
Regarding to the Symfony docs it should be no problem to configure Doctrine to manage different database connections and entity managers.
However I do not completely understand the process on how to setup this use case:
Assume the Symfony project has different data entities DataEntity1, DataEntity2, etc. and different infrastructure entities Infrastructure1, etc..
How to tell Doctrine to initialize the archive DB with the data entities only?
How to move the entities between the DBs? Is loading them from entity manager 1 and persisting them in entity manger 2 the correct way?
Is there any best practice on how to do this?
If I understand your question correctly, you should use the prefix option for the mapping configuration.
prefix
A common namespace prefix that all entities of this mapping share.
This prefix should never conflict with prefixes of other defined
mappings otherwise some of your entities cannot be found by Doctrine.
This option defaults to the bundle namespace + Entity, for example for
an application bundle called AcmeHelloBundle prefix would be
Acme\HelloBundle\Entity.
Have a look at https://symfony.com/doc/3.4/reference/configuration/doctrine.html it shoul help you.
To move the entities between the two DBs, you should have two entity managers and use the correct one to persist olders accounts.
Hope this helps.
I'm learning the Doctrine ORM and I'm loving, but I have a question about how remap a already mapped entity.
I created some of attributes in my table, and I want to map them to my entity. The problem is that I have some of business rule methods on my entity and I can' t lose them, so I need to remap the class and convert to entity without lose the already existed methods.
Actually I use the commands below:
php doctrine orm:convert-mapping --from-database --force annotation /path/project/models
php doctrine orm:generate:entities --update-entities --generate-methods=1 /path/project/models
So, you can help me? How?
I saw old reference (3 years ago) to OneToMany Unidirectional (foreign key) not being implemented:
https://groups.google.com/d/msg/doctrine-user/y8du6cafhdA/QnY_h8NjD10J
I don't see it in current documentation and have also tried using JPA 2.0 onetomany unidirectional annotations and they don't work on Doctrine 2.3.3.
So can I assume OneToMany Unidirectional is still not implemented?
OneToMany Unidirectional is still not implemented as of Doctrine 2.3.3. I base this on the following response from Doctrine User Google Group:
https://groups.google.com/forum/#!topic/doctrine-user/rXLvbhbBXj0
I have two entities related with many to one relation but each one belongs to a bundle.
When forcing the update in the database I get the following error
the target -entity cannot xxxx\Bundle1\Entity be found in xxxx\bundle2\entity
Any ideas please??
Just create an entity extending xxxx\Bundle1\Entity in your xxxx\bundle2 and make the relationship between two xxxx\bundle2 entities.
i ran into the following problem and after hours of searching on the web i don't find any solution.
I want to have a "3-Entity Relationship" between the Entity Project, User and Role.
A Project have many users, and a User can be member of many projects. But in every Relationship between Project <--> User the User can have a different Role.
How can i solve this with Doctrine2?
Many thanks in advance!
EDIT
An little codeexample would be very nice :)
You should have an N:M association between Project and User. Then every instance of this association has the role property (either as an integer for a fixed list, or as an association to a Role entity). Doctrine unfortunately does not explicitly support properties on associations, so in these cases you should use connector entities: an entity that is in ManyToOne connection to both Project and User. This entity then can hold the role value(s)/association(s), but you have to manage (dis)connecting through these objects.
