applyEdits() addAttachments - optional file/image attachments?

luckachi — Mon, 27 Jun 2022 13:58:58 GMT

As part of my featureForm.on(submit) event, I have a piece of code that grab files from an HTML file input, creates a blob and then adds them as attachments to the record. However, I can't seem to correctly handle the addAttachments process when no files are selected. When there are no files selected, the applyEdits() addAttachments still fires and adds 2 undefined ( dW5kZWZpbmVk) blobs that have a file size of 9, which ends up being the length of the type 'image/jpg'. When I tweak the code to be an if else statement based on the files.length, in the console log I receive an error that "Attachment should have 'data' or 'uploadId'"

/******** ** Feature Form Submit Process ********/ // Listen to the feature form's submit event. Update feature attributes shown in the form. featureForm.on("submit", () => { if (editFeature) { // Grab updated attributes from the form. const updated = featureForm.getValues(); // Loop through updated attributes and assign the updated values to feature attributes. Object.keys(updated).forEach((name) => { editFeature.attributes[name] = updated[name]; }); // grabs the image file and converts it to a blob (req.) for addAttachments to process const blob = new Blob([document.getElementById("photo").files[0]]); // Photo 1 const blobTwo = new Blob([document.getElementById("photoTwo").files[0]], {type: "image/jpeg"}); // Photo 2 if (document.getElementById("photo").files.length === 0) { console.log("no files selected"); } if (document.getElementById("photoTwo").files.length === 0) { console.log("no files selected"); } // When you submit a record with no photos, two attachments still get loaded // a white square with 9 bytes? // // First Photo const attachments = { feature: editFeature, attachment: { globalId: editFeature.attributes.GlobalID, name: "attachment_OBJECTID_" + editFeature.attributes.OBJECTID, contentType: "image/jpeg", data: blob } } // // Second Photo const attachmentsTwo = { feature: editFeature, attachment: { globalId: editFeature.attributes.GlobalID, name: "attachment_OBJECTID_" + editFeature.attributes.OBJECTID, data: blobTwo } } // Setup the applyEdits parameter with updates. const edits = { updateFeatures: [editFeature], // addAttachments: [attachments] addAttachments: [attachments, attachmentsTwo] }; const options = { globalIdUsed: true, // has to be true when adding, updating or deleting attachments rollbackOnFailureEnabled: false // has to be true or at least I think so }; console.log(edits); applyEditsToIncidents(edits, options); document.getElementById("viewDiv").style.cursor = "auto"; } });
