Return Feature Collection and Layers

Clive_S — Fri, 04 Dec 2020 08:55:49 GMT

Greetings,

The script query returns items from Portal, the query doesn't recognise Item_Type??

The aim is to return a Feature Collection and associated Layers, this might be 1 or might be 10. I find it odd that I would have to use an IF loop to return the Feature Type

all_users = portal.users.search(max_users = 700) # The default of max_users = 100 #groups = portal.groups.search(query='owner:*', max_groups=50) #groups = portal.content.search(query='owner:*', item_type='Feature*') groups = portal.groups.search('title:*', max_groups=50) ## output file outFile = (r"C:\Users\users\Documents\local\Programme\GIS Data Catalogue\GIS_Items.csv") with open(outFile, 'w') as csvfile: filewriter = csv.writer(csvfile, delimiter=',', quotechar='|', quoting=csv.QUOTE_MINIMAL) filewriter.writerow(['group_id', 'group_title', 'group_owner', 'item_id', 'item_title', 'item_type', 'item_owner']) for group in groups: # ### Prints the Group Name + Owner # #print(group.title, group.owner) for user in all_users: #print(group.id, group.title, group.owner) #### List the Items in Portal content_item = user.items() for item in content_item: #print(group.id, group.title, group.owner, item.id, item.title, item.owner) rowitem = (group.id, group.title, group.owner, item.id, item.title, item.type, item.owner) filewriter.writerow(rowitem ) ## outFile.close print("END")

Appreciate any pointers.

Regards,

Clive

I added an IF loop to try and remove files.

if item.url != "None":

The != "" or != "None" doesn't have any effect??

In case this is not clear.

I have a number of Feature Serveries that have layers that I want to interrogate/return and loop through. I return the Feature Service, but can't return the Layers??

Hi Clive,

Could it be that you want to check for python's None type rather than the string "None"?

maybe try:

if item.url != None:

or maybe even:

if item.url != None or item.url != "": # to also capture empty strings

also, I could be wrong but you won't need the parentheses around your csv path. If it still works for you then thats alright.

## output file outFile = r"C:\Users\users\Documents\local\Programme\GIS Data Catalogue\GIS_Items.csv"
