Looks like I marked this one as solved a hair too quickly…
Here is what I have so far to attempt to get the LastModification attribute:
import json
## get gateway context to grab project manager
from com.inductiveautomation.ignition.gateway import IgnitionGateway
gw = IgnitionGateway.get()
project_manager = gw.getProjectManager()
project_names = [name for name in project_manager.getProjectNames()]
project_manifests = []
projects = [project_manager.getProject(name).get() for name in project_names] ## Need to get() from the java "Optional" object
for project in projects:
manifest = project.getManifest()
jsonManifest = json.loads(manifest.toJson(manifest))
project_manifests.append(jsonManifest)
## get all resources and loop over them to find the latest timestamp from 'LastModification' attribute
resources = project.getAllResources()
latest = None ## update this timestamp whenever a more recent timestamp is encountered.
for resource in resources:
if resource.getProjectName() == project.getName():
return({'json': resource}) ## this returns an object with projectName, resourcePath, and resourceType attributes
return({'json': dir(resource)}) ## this returns a list that does not include 'getAttribute' or 'getAttributes'..
return({'json': resource.getAttributes()}) ## this also throws attribute error
lastModification = resource.getAttribute('LastModification') ## this throws attribute error
d = {'project_names': project_names, 'project_manifests': project_manifests}
return({'json': json.dumps(d)})
This is in a python doPost web dev resource. Gateway is running 8.1.10. You can see that I have debug return statements in the code to inspect the resource object in that last loop. The dir(resource) almost returns the same list that I would expect of the ProjectResource object, but it is missing the getAttribute and getAttributes methods I need.
