Why won't apply edits update, but adding a new point will for Features?

ChrisSergent — Sun, 12 Dec 2021 00:44:39 GMT

My application will create new feature points, but will not update existing points. Is there different syntax besides the applyEdits to perform an update? I have debugged and the attributes are there when I start. They just don't take, which is why I thought my syntax may be wrong.

Here is a block of code that I am trying to use for one of the updates:

 // get sign attributes from form and submit
    var updateSigns = function () {


        // alert(domClass.contains("attributesSignModal", "in"));


        var attributes = {
            // TODO: not sure if this is needed  
            //requestreceived: null
        };
        var currentDate = new Date(); // current date is defined but never used.
        var graphic;




        graphic = new Graphic(app.currentGeometry);


        query("#attributesSignModal input, #attributesSignModal select, #attributesSignModal textarea").forEach(function (formInput) {
            attributes[formInput.name] = formInput.value;
        });


        // Form validation - ensures that the values for the data are here if left blank
        if ((attributes.installed === undefined) || (attributes.installed === "")) {
            attributes.installed = null;
        }
        if ((attributes.signId === undefined) || (attributes.signId === "")) {
            attributes.signId = null;
        }
        if ((attributes.supportId === undefined) || (attributes.supportId === "")) {
            attributes.supportId = null;
        }


        graphic.setAttributes(attributes);
        stopCaptureRequest();


        console.log(attributes);
        app.signLayer.applyEdits(null, [graphic], null).then(function (response) {
            console.log(response);
            app.signLayer.refresh();


        });


    };

and here is an addSign that does work:

 // get sign attributes from form and submit
    var addSigns = function () {


       // alert(domClass.contains("attributesSignModal", "in"));


        var attributes = {
            // TODO: not sure if this is needed  
            //requestreceived: null
        };
        var currentDate = new Date(); // current date is defined but never used.
        var graphic;




        graphic = new Graphic(app.currentGeometry);


        query("#attributesSignModal input, #attributesSignModal select, #attributesSignModal textarea").forEach(function(formInput) {
            attributes[formInput.name] = formInput.value;
        });


        // Form validation - ensures that the values for the data are here if left blank
        if ((attributes.installed === undefined)|| (attributes.installed === "")) {
            attributes.installed = null;
        }
        if ((attributes.signId === undefined) || (attributes.signId === "")) {
            attributes.signId = null;
        }
        if ((attributes.supportId === undefined) || (attributes.supportId === "")) {
            attributes.supportId = null;
        }


        graphic.setAttributes(attributes);
        stopCaptureRequest();


        console.log(attributes);  
        app.signLayer.applyEdits([graphic], null, null).then(function (response) {
            console.log(response);
            app.signLayer.refresh();
            
        });


    };

and finally, here is my latest github commit:

Chris,

the applyEdits method take an arrays for adds, updates, and deletes. Depending on which operation you are attempting to do will determine which position you need to have that array in.

applyEdits(adds?, updates?, deletes?, callback?, errback?)

Notice for updates the array has to be in the second position.

applyEdits(null, [your updates], null, callback, errback)

ChrisSergent — Fri, 22 May 2015 21:46:22 GMT

Right and that's the way I have it in my first block of code.

Chris,

Sorry I did not see that. Try adding an error callback function so that you can see what the issue is. Right not you only have a result call back.

Robert,

I'll have to look into that hopefully at home if I can this weekend. Our area looks like it's shutting down right now.

I was getting an error on this statement though, couldn't figure out why: app.attributesSignModal.modal("hide");

Chris,

Are you sure that there is a modal function on this app.attributesSignModal object?

Re: Why won't apply edits update, but adding a new point will for Features?

ChrisSergent — Tue, 26 May 2015 14:18:18 GMT

Yes, modal is a function. There is a file modal.js and I have use it on other elements to hide or show.

ChrisSergent — Tue, 26 May 2015 14:23:42 GMT

I am not sure what to write for a callback. Do you have an example?

You may also want to check that the OBJECTID for the feature you're trying to update is included in the attributes. I know that tripped me up before.

Re: Why won't apply edits update, but adding a new point will for Features?

ChrisSergent — Tue, 26 May 2015 15:11:52 GMT

I've checked this. All items have an OBJECTID. Or do you think I need to include this on my form?

Re: Why won't apply edits update, but adding a new point will for Features?

BethManghi — Tue, 26 May 2015 15:42:05 GMT

Try including it in the form so that it gets passed with the updated attributes.

ChrisSergent — Tue, 26 May 2015 19:18:36 GMT

This didn't work. With my latest updates I get this error message:

and I have updated my project here:csergent45/streetSigns at 119dc2ec277a347c066f92fa13e0ca76f182fb8f · GitHub

ChrisSergent — Sun, 12 Dec 2021 00:44:42 GMT

I did take out the hide line and then received an error, unable to completed function, so I believe it's something before I hide the form.

The code never makes it to the second line of code shown here:

app.signLayer.applyEdits([graphic], null, null).then(function (response) {
            console.log(response);
            app.signLayer.refresh();
           
        });

In your app it looks like you create a new graphic for the update feature operation. If you are updating an existing feature you should already have a graphic. So instead of creating a new one just get the existing one and update what has changed (attributes or geometry).

graphic = new Graphic(app.currentGeometry);

KyleMorgan — Tue, 26 May 2015 22:18:38 GMT

Hey Chris,

Make sure your form is submitting the correct "type" during your POST operation. Number fields and ObjectIDs can't be passed as strings (wrapped in ' or "). You can use parseInt(<field>)/parseFloat(<field>) on the appropriate text fields before applying the API applyEdits() call.

Re: Why won't apply edits update, but adding a new point will for Features?

ChrisSergent — Tue, 26 May 2015 22:34:33 GMT

I am just updating the attributes, but I don't see how to exclude the graphics.

Re: Why won't apply edits update, but adding a new point will for Features?

ChrisSergent — Tue, 26 May 2015 22:35:08 GMT

Tried it out. No luck so far. Going to try again in the morning.

Re: Why won't apply edits update, but adding a new point will for Features?

KellyHutchins — Tue, 26 May 2015 22:36:54 GMT

Its not a matter of excluding the graphics its a matter of updating the existing feature (graphic) rather than creating a new one.

Re: Why won't apply edits update, but adding a new point will for Features?

ChrisSergent — Tue, 26 May 2015 22:39:49 GMT

Would taking new out work then for that?

Re: Why won't apply edits update, but adding a new point will for Features?

KellyHutchins — Tue, 26 May 2015 22:44:21 GMT

No. How are you determining that the feature is being updated? Is the user clicking on it? If so then the click event should give you access to the feature that is being updated. If you look at the API reference for the Feature Layer click event you'll see that the returned object includes the graphic that was clicked.
