Zapsat přílohy do AGOL Feature Service

Question

Zajímalo by mě, jestli někdo měl úspěch se zápisem příloh do existujícího feature service hostovaného na ArcGIS Online pomocí rozšíření Data Interop. Snažil jsem se spustit zjednodušený pracovní postup (funguje stejně jako nástroj append), ale nepodařilo se mi zapsat přílohy do feature service.<\/P> Pro informaci, používám FME Workbench 2024.0.1.0 a ArcGIS Pro 3.1.1. Workspace je nastaven následovně:<\/P> - Čtečka a zapisovač odkazují na feature services hostované na ArcGIS Online. - "Ending_Locations_A_V2", což je Reader, má 10 prvků, z nichž 2 mají přílohy. - "Ending_Lovations_B_V2" má přesně stejnou datovou strukturu a začíná prázdný, přílohy jsou povoleny.<\/P> <\/span><\/P>Podařilo se mi potvrdit čtení příloh:<\/P><\/span><\/P>Tento proces probíhá bez chyb a pouze varuje o tom, že OBJECTID a GLOBALID jsou pouze pro čtení, což by neměl být problém.<\/P>Každá pomoc je vítána!<\/P>-Brian<\/P> <\/P>

@BrianGiroux I am glad we got this figured out with your AGOL to Enterprise attachment backup workflow.

Let me know if I can be of further assistance as you address the next step in your change detection workflow.

My apologies for this delayed reply.  Data Interoperability does support writing attachments in AGOL (or Enterpise) primarily by using AGOL's REST API. This was my presentation at the last UC - UC24 proceeding to Intro to Data Interop technical session

Here's a guide on what to use in the ESRI stack when working with attachments.

Attachments in feature layers are blobs stored in the data store.

* HFL attachments have simple 1:M relationship in AGOL
* GDB or FS by reference use relationship class allowing 1:1 up to M:N.

Patterns of Use for reading/writing/moving attachments are the following:

For simple use cases, use core product tools (Python, GP tool)

* Attachments collected with ESRI Fields Apps

For complex workflows like below:

* Move attachments from non-ESRI to ESRI format
* Manage attachments, eg change detection 
* Store as hyperlink, database blob or file on disk
* Reports

Leverage the REST API and for tools use Data Interop of no-code/low code solution or Python or Notebook for coded solutions.

For the following workflows:

* Backup or Archive – use Replica or Download as FGDB (in the case of AGOL/Enterprise feature services with attachments)

Non traditional attachment questions can be addressed using Arcade as described in this Blog.

Please send me a note rsalvaleon@esri.com, if you want to pursue further a Data Interop solution. There is a clear pattern when working with attachments and each pattern would have some slightly different approach.

Hi Christopher,

Thanks for confirming my suspicion -- I'll have to look into the alternatives.
