what is connection_cache_size in zodbconn.uri(pyramid-framework-zodb-scaffold)?

it helps some times The parameter configures how many objects the connection caches in RAM. Note that this is an object count, not a size in bytes.
Keeping a number of objects in memory reduces load times, but increases RAM size. What you set the number to then depends on how much RAM you have and how big your objects are.

Pyramid + ZODB Image storing

Pyramid + ZODB Image storing

I hope this helps . The error you see is unrelated to image storing in the ZODB.
To store larger pieces of data, you really want to use a ZODB Blob instead of putting the image data directly in an attribute. Blobs are stored separately on disk and do not flush the ZODB cache, and can be streamed back to the client on access again.
code :
from ZODB.blob import Blob

uid = Blob(imagebinary.read())
from pyramid.response import Response

def serveimage(request):
    # retrieve uid from somewhere
    resp = Response(content_type='image/jpeg')
    resp.app_iter = uid.open('r')  # open for reading
    return resp

it helps some times To read the information you'll need to have the original classes available for import; the pickles can only be loaded into the original class structures.
I am not sure that will work all that well; there are a lot of assumptions and dependencies that may clash with the Pyramid framework, or cannot be satisfied without the Zope framework being available.

should help you out The pyramid_tm package is used; it installs a Tween that manages the transaction.
It simply starts a transaction for every request, and if the request was successful the transaction is committed, and aborted otherwise.

may help you . Alas, the list of scaffolds available when you are using PyCharm's "New Project" Pyramid support is limited to the scaffolds that Pyramid ships with. You will unfortunately need to do it manually, then open the project.
