ok. so I am still trying to get erattachment working. I have a little test app.
I can select an image (pdf, jpg) and 'upload' it. When I click its link it will
show in the ERAttachmentViewer.
however if I quit and relaunch my app, the images do not reload from the
database (postgresql).
i see in the eclipse logs:
evaluateExpression: <com.webobjects.jdbcadaptor.PostgresqlExpression: "SELECT
t0.attachmentDataID, t0.available, t0.configurationName, t0.creationDate,
t0.filesystemPath, t0.height, t0.id, t0.mimeType, t0.originalFileName,
t0.ownerID, t0.parentID, t0.proxied, t0.s3Path, t0.size, t0.smallData,
t0.storageType, t0.thumbnail, t0.webPath, t0.width FROM ERAttachment t0 WHERE
((t0.storageType = ?::varchar(10) OR t0.storageType = ?::varchar(10) OR
t0.storageType = ?::varchar(10)) AND t0.id = ?::int4) LIMIT 1" withBindings:
1:"db"(storageType), 2:"file"(storageType), 3:"s3"(storageType), 4:1(id)>
Sep 24 12:28:12 AttachmentTest[54058] DEBUG NSLog - fetch canceled
Sep 24 12:28:12 AttachmentTest[54058] DEBUG NSLog - 1 row(s) processed
Why the fetch canceled, I don't know. Little things I see that shouldn't
matter, 'FROM ERAttachment'. of course postgresql will fold the name to
lowercase automatically and my table is named erattachment so this shouldn't
matter.
I see in the postgresql logs right after I click the hyperlink to view the
image:
[unknown]LOG: execute <unnamed>: SELECT t0.data, t0.id FROM ERAttachmentData
t0 WHERE t0.id = $1::int4
[unknown]DETAIL: parameters: $1 = '1'
so it is trying to get the link. maybe I am saving bad data?
should I be massaging the data before trying to save it to the backend?
I do have in my properties file:
er.attachment.ImageMeta.image.storageType=db
my migrations and connection dict look like:
# Migrations
er.migration.migrateAtStartup=true
er.migration.createTablesIfNecessary=true
er.migration.modelNames=AttachmentTest
AttachmentTest.MigrationClassPrefix=com.eltek.migrations.AttachmentTestMigration
