Using AttachmentManager to Download Attachments Saves in Separate Folders

The issue I'm having is with the AttachmentManager module. I wrote a quick code to download all of the attachments for a feature layer stored on ArcGIS online. 

 

############# Get logged in and set up ###############

from arcgis.gis import GIS
PortalUrl = "https://www.arcgis.com"
username = ""
password = ""

FeatureLayerID = "e5c2bdc5755e4e21ab578550f2fa12a3"

SavePath= r"C:\Users\cschooley\Documents\Work\Heritage\Photos"

################# End Set-up #######################

if username == "" and password == "":
    gis = GIS()
else:
    gis = GIS(PortalUrl, username, password)

FeatureLayer = gis.content.get(FeatureLayerID)

layer = FeatureLayer.layers[0]

layer.attachments.download(oid = 1, save_path=SavePath)

 

It works just fine, but the issue I am having is that when it saves into the path I created, it creates a new folder for the ObjectID of that feature and the AttachmentID of that feature, nesting my photos behind two of their own folders. 

 

['C:\\Users\\cschooley\\Documents\\Work\\Heritage\\Photos\\1\\18\\2015-04-11 10.35.42.jpg']

 

I am wondering if there is a way to work around this. I would like to have the photos save directly into the 'photos' folder without the creation of the other folders. 

I suppose using the os module could work, but that's a little over my head. I found this  article which has been kind of helpful, but I couldn't get his code to work for me, which is why I wrote this one above. It was simpler and didn't have the extra stuff I didn't need. I only need to download the photos, not necessarily have all the information (ObjectIDs, etc.) attached to them. 

Thank you. 

 

P.S. The feature ID used in the code is a public one, not the one I'm actually trying to use since that one is protected within my organization. It's from the JoshuaTreeHike feature server. It's the same set-up as mine though, where the Attachment IDs don't necessarily match the ObjectIDs.

Hi cshooley,

Maybe you can used this workaround with os and shutil module to copy jpg after downloaded at Photos dirname as below :

 

############# Get logged in and set up ###############
import os
import shutil
from arcgis.gis import GIS
PortalUrl = "https://www.arcgis.com"
username = ""
password = ""
FeatureLayerID = "e5c2bdc5755e4e21ab578550f2fa12a3"
SavePath= r"C:\Users\cschooley\Documents\Work\Heritage\Photos"

################# End Set-up #######################
if username == "" and password == "":
    gis = GIS()
else:
    gis = GIS(PortalUrl, username, password)
FeatureLayer = gis.content.get(FeatureLayerID)
layer = FeatureLayer.layers[0]
layer.attachments.download(oid = 1, save_path=SavePath)

################# Copy image #######################
for root, dirs, files in os.walk(SavePath):
    for f in files:
        if f.endswith('.jpg'):
            print("Copy jpg: {0}".format(str(f)))
            pathOriginal = os.path.join(root,f)
            pathTarget = os.path.join(SavePath,f)
            shutil.copyfile(pathOriginal, pathTarget)

### remove folders into Photos if you want
##for d in os.listdir(SavePath):
##    if os.path.isdir(os.path.join(SavePath,d)):
##        shutil.rmtree(os.path.join(SavePath,d))

 

Hope this help you,

Best regards,

Fred

Thank you! That worked great. I had figured out how to get a list of all my files with this code:

list_dir = []
for root, dirs, files, in os.walk(SavePath):
    for file in files:
        list_dir.append(file)

But couldn't get any further than that. Now I think I can use your

for root, dirs, files in os.walk(SavePath):
    for f in files:
        if f.endswith('.jpg'):
            print(r"Copy jpg: {0}")
            PathOriginal = os.path.join(root,f)
            PathTarget = os.path.join(SavePath, f)
            shutil.copyfile(PathOriginal, PathTarget)

To get all the files, not just jpegs. Something like this:

for root, dirs, files in os.walk(SavePath):
    for f in files:
       print("Copy jpg: {0}".format(str(f))
       PathOriginal = os.path.join(root,f)
       PathTarget = os.path.join(SavePath, f)
       shutil.copyfile(PathOriginal, PathTarget)

 

Thanks again!

A secondary issue, and I don't know if you can help me here, but if some photos have the same name, there should be a way to rename the doubles right? So that they don't overwrite each other?

Best way is to check if jpg name exist before copy it.

See https://pro.arcgis.com/en/pro-app/latest/arcpy/get-started/checking-for-existence.htm

Right. So, that checks if something exists, but doesn't help with the issue of the shutil.copy overwriting if something exists. I'm downloading attachments from a feature layer where the attachments on different layers have the same name, but aren't the same picture and I want all of the pictures. 

From my reading I need to add something kind of like this to rename them before they save:

 

while os.path.exists(f + "_" + str(i)):
     i+=i

 

Not that exactly of course, but to add a number or something on the end of it so it doesn't overwrite the previous image.

Hi,

Try complete script below:

############# Get logged in and set up ###############
import os
import shutil
from arcgis.gis import GIS
PortalUrl = "https://www.arcgis.com"
username = ""
password = ""
FeatureLayerID = "e5c2bdc5755e4e21ab578550f2fa12a3"
SavePath= r"C:\Users\cschooley\Documents\Work\Heritage\Photos"

################# End Set-up #######################
if username == "" and password == "":
    gis = GIS()
else:
    gis = GIS(PortalUrl, username, password)
FeatureLayer = gis.content.get(FeatureLayerID)
layer = FeatureLayer.layers[0]
layer.attachments.download(oid = 1, save_path=SavePath)

################# Copy image #######################
for root, dirs, files in os.walk(SavePath):
    for f in files:
        if f.endswith('.jpg'):
            print("Copy jpg: {0}".format(str(f)))
            pathOriginal = os.path.join(root,f)
            pathTarget = os.path.join(SavePath,f)
            
            if os.path.exists(pathTarget):
                pathTarget = pathTarget[:-4] + "_copy" + pathTarget[-4:]
                
            shutil.copyfile(pathOriginal, pathTarget)

### remove folders into Photos if you want
for d in os.listdir(SavePath):
    if os.path.isdir(os.path.join(SavePath,d)):
        shutil.rmtree(os.path.join(SavePath,d))

Hope this help you,

Thank you.  I was able to go through this one and make one that worked out for me.
