Support for files in fixtures

[viliam-husar]

Proposed changes allows to load files in fixtures. It is compatible with the symfony cookbook article about uploading files in doctrine and also with VichUploaderBundle. If you consider these changes as acceptable I will update docs. I also changed the composer.json, because it was impossible to make it work work with symfony 2.2.0BETA.

Example:

model:                          App\Bundle\SomeBundle\Entity\SomeDocument
tags:                           [ test, dev ]
save_in_reverse:                false
file_fields:                    [ file ]
persistence:                    orm
fixtures:
   some_document_1:
        name: 'xxx'
        file: some_document/1.txt

The path is relative to fixtures yml file.

It's "$file" here, but it was "$path" in the constructor

[viliam-husar]

That is because $fixtures_data in constructor is $file. (Correction would require small refactoring.)

What was blocking with 2.2?

Composer output:

Problem 1
    - Installation request for khepin/yaml-fixtures-bundle dev-patch-files -> satisfiable by khepin/yaml-fixtures-bundle dev-patch-files.
    - Conclusion: remove symfony/symfony 2.2.x-dev
    - Installation request for doctrine/doctrine-fixtures-bundle dev-master -> satisfiable by doctrine/doctrine-fixtures-bundle dev-master.
    - Conclusion: don't install symfony/symfony 2.2.x-dev
    - doctrine/doctrine-bundle 1.2.x-dev requires symfony/framework-bundle >=2.2.0-beta2,<2.3-dev -> satisfiable by symfony/symfony 2.2.x-dev, symfony/symfony 2.2.x-dev, symfony/framework-bundle 2.2.x-dev.
    - doctrine/doctrine-bundle 1.2.x-dev requires symfony/framework-bundle >=2.2.0-beta2,<2.3-dev -> satisfiable by symfony/symfony 2.2.x-dev, symfony/symfony 2.2.x-dev, symfony/framework-bundle 2.2.x-dev.
    - don't install symfony/framework-bundle 2.2.x-dev|don't install symfony/symfony v2.2.0-BETA1
    - Installation request for symfony/symfony 2.2.* -> satisfiable by symfony/symfony 2.2.x-dev, symfony/symfony v2.2.0-BETA1.
    - Installation request for doctrine/doctrine-bundle 1.2.* -> satisfiable by doctrine/doctrine-bundle 1.2.x-dev.

This wasn't wery helpful, but finally the problem part is:

"doctrine/doctrine-fixtures-bundle": "2.*@alpha",

beacuse of it's composer.json. When I changed (in your original composer.json) only this dependency for

"doctrine/doctrine-fixtures-bundle": "dev-master",

problem disappeared. So if you want I can change composer.json again.

[viliam-husar]

And I think that dependency for

"doctrine/data-fixtures": "1.*@alpha",

is not required.

[khepin]

That's kind of me being a freak about tagging all versions and never using dev-master... I'll have a look

It's been merged on a "merge" branch.
Needs tests before I merge on master
