ArcGIS Field Mapsで関連レコードを使用した計算式の利用

Question

新しいフィーチャに属性情報を自動的に入力して時間を節約し、ミスを減らしたいと思ったことはありませんか？ArcGIS Field Mapsの計算式を使えば可能です！このビデオは2022年8月にArcGIS Field Mapsを使用して録画されました。一般的な計算式と例についての詳細は、こちらをクリックしてください。さらにフィールドデータ管理のトレーニングについては、Esriの「Field Data Collection and Management Using ArcGIS」コースをご覧ください：https://bit.ly/3EyRgd0<\/P> <\/iframe><\/P>以下はコピー＆ペーストできる類似のコードです:<\/P> \/\/ 消火栓のフィーチャセットを取得 var hydrants = FeatureSetByRelationshipName($feature, 'wHydrant', ['facilityid'], true)<\/P> \/\/ 最初の消火栓を取得（通常は1つだけ） var hydrant = First(hydrants)<\/P> \/\/ 消火栓があれば、そのfacilityidを返す。 \/\/ なければnullを返す if (!IsEmpty(hydrant)) { return hydrant['facilityid'] } else { return null }<\/P>

I am having an issue with this code because now I am trying to pull a value instead of a text field. I am trying to pull a value from the related record as an input, but I just keep getting  "Test execution error: Cannot read properties of null (reading 'toString'). Verify test data."

Hi @JordanHeiman yes - that is possible! I just tested it and provided some screenshots. 1. This is where I clicked on a point and saw the related Parent table. 2. After adding a record to the Parent table, I could also add a record to the child table. Now I can see the parent table is related to the point and the child table. I would read this tech support article first to make sure your data relationships are set up correctly for Field Maps https://support.esri.com/en-us/knowledge-base/how-to-set-up-related-tables-in-arcgis-pro-for-use-in-a-000028010. You would need to create a relationship class between the point/line/poly layer and the parent table AND create a relationship class between the parent table and child table.

From there, here are is a great Learning Plan to get started with Field Maps https://learn.arcgis.com/en/paths/try-data-collection/

There are a lot of helpful blogs as well https://www.esri.com/en-us/arcgis/products/arcgis-field-maps/resources

We also offer a 2 day instructor led course that is about Field Data Collection and includes Field Maps https://www.esri.com/training/catalog/5952ca883885672fa2147a4f/field-data-collection-and-management-using-arcgis/

This video was super helpful! I am trying to setup a form with this feature but I was also hoping to collect data to another table that is related to the first table. In your example this would be like having a child table from the inlet inspection that can also be filled out. Previously we were using Survey 123 and were able to have a repeated record within a form but we are considering switching to Field Maps. Is this sort of set up possible with Field Maps?

Also, what is the best resource or training videos for learning about setting up Field Maps?
