How to link a document to a .pdf file + filter on extension about media-bundle HOT 11 OPEN

indeed i think we miss a cmf media FileType that would look very similar (and probably can share code with) ImageType. do you want to have a look at what we do for the image and try to generalize that to handle plain files?

we already have the FileController with downloadAction - i guess that should have a viewAction that omits the Content-Disposition so the file can be viewed in a browser directly (again without duplicating all the code there)

for the file extensions, that would be a general symfony question. i found nothing here http://symfony.com/doc/current/reference/forms/types/file.html
this is a whole can of worms, as you have both the mime type and the extension to worry about, and in general can not trust the client to respect things. but i propose you discuss that in the core symfony channels as its not related specifically to the cmf.

@rmsint do you have inputs for nicolas?

Ok David thanks for your answer.

So just to be sure, the first line of the mediabundle doc say :

Media can be images, binary documents (like pdf files), embedded movies, uploaded movies, MP3s, etc.

So you confirm than right now only images works ?

Did somebody already try to use SonataMedia with the CMF ?

Thanks a lot

Hey Nicolas,

Underneath some inputs from my side, hope it helps you further. (It is some time ago I worked with Symfony, so my knowledge may be a bit rusty.)

Form Type
For a file upload you can use the symfony file form type. After that persist it to phpcr using the Symfony\Cmf\Bundle\MediaBundle\File\UploadFileHelperDoctrine:handleUploadedFile. See the webtest/demo app for an example: https://github.com/symfony-cmf/MediaBundle/blob/master/Tests/Resources/Controller/PhpcrFileTestController.php#L58

Of course you can make it easier, fe. to use with sonata admin, by creating a form type cmf_media_file that puts the last step in a transformer. Actually, the transformer Symfony\Cmf\Bundle\MediaBundle\Form\DataTransformer\ModelToFileTransformer is already handling files and images, so it is just a matter of creating the form type. You can also control then how an uploaded file is rendered, fe. you maybe want to display the filename and filesize and/or a thumnail for your pdf. If it is that generic, and more people can benefit, you could do a PR?

Here a the steps and links how this is done for the cmf_media_image:

• the cmf_media_image form type extends the Symfony file type, see https://github.com/symfony-cmf/MediaBundle/blob/master/Form/Type/ImageType.php#L42
  • the ModelToFileTransformer is configured in the buildForm method, it helps you to persist to phpcr. It accepts
  • notice some configuration params, about imagine, being forwarded to the template
• the ModelToFileTransformer createa a FileInterface object, PR #82 adds to also use the Symfony\Cmf\Bundle\MediaBundle\File\UploadFileHelperDoctrine:handleUploadedFile here
• a custom twig widget does some image rendering, see https://github.com/symfony-cmf/MediaBundle/blob/master/Resources/views/Form/fields.html.twig
  • in this widget an imagine filter is being used, however you can also use fe. a download url in your widget. You can then use the twig function cmf_media_download_url, see Symfony\Cmf\Bundle\MediaBundle\Twig\Extension\CmfMediaExtension and Symfony\Cmf\Bundle\MediaBundle\Templating\Helper\CmfMediaHelper

See also https://github.com/symfony-cmf/symfony-cmf/wiki/Media, it describes some ideas we had before writing this bundle. If I remember correctly there has been some discussion about a PDF having a preview image, there should be a note about this.

File extensions
If the file extensions are important to your application you can add some guards to your model. Fe. a PDF file that only accepts the pdf extension. You could use the symfony validation and/or add guards directly in the model for the content setters. Whatever suits your app best I would say. Symfony has already some code to map between mime-types and extensions, see https://github.com/symfony/HttpFoundation/blob/master/File/UploadedFile.php#L173.

thanks a lot for the inputs roel.

regarding mime-types, see also #77

@nicolas-bastien, for me: yes and no. No with the CmfMediaBundle. Yes, before this bundle existed I had an integration working with SonataMedia and the CMF. I think now 70% of the work is done for integrating with SonataMedia. The Gaufrette adapter is created to do the heavy lifting of the integration with SonataMediaBundle. I expect most work needs to be done in the SonataMediaBundle, and maybe some bugfixes in the CmfMediaBundle.

Hi, thanks so much for your answers.

I will do that next week. I need to make it work on my project before the
end of april.
Then I'll help improving the bundle.

Thanks again for your help

Nico

@nicolas-bastien see sonata-project/SonataMediaBundle#509. Another discussion to pickup integration with SonataMediaBundle

from media-bundle.

do we need to do anything on the cmf side?

Hi,

So thanks to your help I managed to make a file input field.
One problem is that every time I update my document the file (like the
image) field is deleted.

To correct that I made a custom admin and use a sonata_type_admin.

So my media solution is not really great, I'll come back when something
will be working.

you did see that our models check if the file is being set to null and in that case do not remove the child?
