Retrieving all feature layer views with View Manager list()

GIS_utahDEM

I am trying to return a list of all feature layer views of a specific item. I am able to successfully do this with the arcgis.gis ViewManager .list() method, however it only returns the first 100 (I know, I've got a lot of view layers). Is there a way to overrule this and make it return all of them? I should have about 350 for every jurisdiction in my state.

It looks like the problem is the logic as written doesn't incorporate paging. ViewManager.list() uses the relatedItems endpoint which itself does support paging. The supporting method that needs to be updated is related_items in arcgis/gis/__init__.py.

You could fix it rather easily by introducing a while loop and adding "start" and "num" parameters in the postdata. The num value should be 100 based on what you've shared. If you decide to give this a try, I would recommend experimenting in a new python environment as changes to the source voids technical support.

I've not tested this, but something like this should get you more or less started (you will need to open/save the file as an Administrator):

 

    def related_items(self, rel_type: str, direction: str = "forward"):
        if rel_type not in self._RELATIONSHIP_TYPES:
            raise Error("Unsupported relationship type: " + rel_type)
        if not direction in self._RELATIONSHIP_DIRECTIONS:
            raise Error("Unsupported direction: " + direction)

        related_items = []

        postdata = {"f": "json"}
        postdata["relationshipType"] = rel_type
        postdata["direction"] = direction
        postdata["num"] = 100
        postdata["start"] = 0
        keep_going = True
        while keep_going:
            resp = self._portal.con.post(
                "content/items/" + self.itemid + "/relatedItems", postdata
            )
            if len(resp["relatedItems"]) > 0:
                postdata["start"] = postdata["start"] + 100
                for related_item in resp["relatedItems"]:
                    related_items.append(Item(self._gis, related_item["id"], related_item))
            else:
                keep_going = False
        return related_items

 

 

 

 

 

In any case, I would recommend logging an enhancement with Esri Technical Support for paging to be added.
