RE: P4a subtyper / P4a Audio Broken with Blob Storage -2

[Eric Tyrer]

I've found that in p4a.ploneaudio.atct line 193 has

@property def audio_type(self): mime_type = self.context.get_content_type() accessor = component.getAdapter(self.context, interfaces.IAudioDataAccessor, unicode(mime_type))

does this need to have/use ATblob? mime type or interface?

Uploading an audio or video file the subtyper fails with the following error.

Error Message is:

Traceback (innermost last):

Hi Eric,

I had hoped to merge all the plone.tv code back into p4a during the
Plone video sprint, but didn't get time to do it. Here are the things
you need to do:

Make a directory called /blob with these files:
/blob
__init__.py
atct.py with the content of this: http://pastie.org/699381
configure.zcml with the content of this: http://pastie.org/699383
interfaces.py with the content of this: http://pastie.org/699384

and then in the top level configure.zcml, add this line:

<include package=".blob" />

Let me know if that works for you.

Nate

Hi Nate,
I don't know how that worked for Eric, but I now get another error.
The file appears to upload properly and the entry appears in the
folder view, but the metadata is missing. There is no album art or
time displayed, however the file does play properly. When I try to
view the audio file I get the following traceback:

First I moved p4a.ploneaudio to my src/ folder so that my buildout
would not overwrite my changes.

I made the mentioned files and directory but I am getting a zcml
error. I will post the trace later.

Hi Nate,
For some reason the adapter factories are not being called. Is the
interface more specific for the original adapter factory?

Thanks,
Allen

Well I got it to work. Sort of.
I put the files that Nate posted in my own product, but the adapter
factories were not being called. I did get it to work by deleting the
line:
<adapter factory=".atct.ATCTFileAudio" />
from configure.zcml in p4a.ploneaudio and the line:
<adapter factory=".atct.ATCTFileVideo" />
from configure.zcml in p4a.plonevideo
Since these files are in the downloaded eggs, they are going to be
overwritten every time I run buildout, so this is just a temporary
solution.

I am using mr.developer to check in/out the p4a stack into my testing buildout (which is just a copy of my production vm). Its pretty cool and moves those eggs to /src so i can muck around with them without overwriting them when i run buildout.

Question, which files did you modify? (based on Nate's post). p4a.subtyper or ploneaudio to get blob storage to work?

I am having a ridiculous time getting audio to show up in the subtyper menu. I am attaching my buildout.

Eric,
I haven't tried mr.developer yet but It sounds great.
I didn't touch p4a.subtyper, just p4a.plonevideo and p4a.ploneaudio.
In those two products I deleted the lines in my above post.
My buildout is somewhat different since I'm using some different
products and I'm also using a modified version of Martin's
Uberbuildout. I think the relevent parts are:
eggs =
plone.app.blob
ZODB3
hachoir-core
hachoir-metadata
hachoir-parser
p4a.plonecalendar
p4a.ploneevent
p4a.ploneaudio
p4a.plonevideo
p4a.plonevideoembed
Products.basesyndication
Products.fatsyndication

zcml =
plone.app.blob
p4a.plonecalendar
p4a.plonecalendar-meta
p4a.ploneevent
p4a.ploneaudio
p4a.plonevideo
p4a.plonevideoembed

I've also got the versions of hachoir-core, hachoir-metadata and
hachoir-parser pined at version 1.2. and ZODB3 pined at version
3.8.3. If that doesn't work I can send you a copy of my complete
buildout.

Hi,

I've started a branch in collective with your changes and a buildout config.
I have made some changes and suddenly I remembered that I shouldn't
try until it works in my plone but get the tests working with plone.app.blob.
Thats what I am trying to get working right now.

Best regards,

Patrick

Allen, Nate & et al.

I moved my p4a.ploneaudio & p4a.ploneaudio to src with mr.developer.

I then created a blob directory within p4a/ploneaudio & p4a/plonevideo with the files created from Nate's pastie links.

I then added <include package=".blob" /> to each of the configure.zcml

Testing by imbedding a youtube video works fine..

However adding either a video or audio file proceeds somewhat normally.

The blobfile is created fine.. looking at the upload in the ZMI shows..

ATBlob at /1/audio-test/test/test

The object is created, however it doesn't automatically identify the object as a video. Changing the subtype to video causes the following error

Traceback (innermost last):

Hi,

I got p4a.ploneaudio working with blob support.
The branch is here:

http://svn.plone.org/svn/collective/p4a/p4a.ploneaudio/branches/blob_support/

Please try it and give some feedback. One thing I did not try are
Images in music files.
If you test that, please be aware that images are NOT made blob aware
per default,
you have to add a zcml statement for that.

Best regards,

Patrick
