Child form

[Leonid]

Hi,
Wondering of recommendations oh how open a secondary (child) form from a main form and return back to the original one after the secondary is submitted. Thoughts welcome!

[Alexander Bautz]

This is more or less what the vLookup plugin is used for: https://spjsblog.com/vlookup-for-sharepoint/

Thx Alex! Would it allow use rules for the fields in the chcild list?

[Leonid]

Looks like I already know the answer to previous question – its yes. Right now Im puzzled to pass ID of a newly created item in a child list to a field in the parent list in a New form

[Leonid]

Here is the part Im not getting. The sample suggests autopopulating parentId in the Child list from parent’s list ID. But that ID doesnt exist in a New form, only in Edit and View forms. My approach is to pass ID from the Child list (after item is created there) to a field in the New form. That doesnt work.

[Leonid]

Continuing with mono- discussion. It appears that ID is not item ID but randomly generated unique ID prior to item creation, and it works. I still need to save child item ID in a parent list because parent list has multiple association with the same child list and reverse ralationship is much simpler.

The other question, whats the best way to make Add Child Record button conditional? E.g. I want to show it only when there is no records in the child list matching query

[Alexander Bautz]

Hi,
As you already have figured out, the _vLookupID column is auto-generated and used to link the two items together.

Also, you cannot get the ID directly from NewForm. What you can try in the Parent form, is to add this code snippet to pick up the last item added and write the ID to a field.

function vlookupChildAddedCallback(){
    var res = spjs.utility.queryItems({
        "listName": "DISPLAY_NAME_OF_CHILD_LIST",
        "query": "<Where><Eq><FieldRef Name='_vLookupParentID' /><Value Type='Text'>"+getFieldValue("_vLookupID")+"</Value></Eq></Where><OrderBy><FieldRef Name='ID' Ascending='FALSE' /></OrderBy>",
        "rowLimit": 1,
        "viewFields": ["ID"]
    });
    if(res.count > 0){
        var newItemId = res.items[0].ID;
        setFieldValue("THE_FIELD_YOU_WANT_TO_SET", newItemId);
    }
}

Replace DISPLAY_NAME_OF_CHILD_LIST and THE_FIELD_YOU_WANT_TO_SET with the correct ones.

To dynamically hide the button if there is items already added you can add this custom js:

function vLookupIsLoadedCallback(fin) {
    if (fin === "NAME_OF_YOUR_VLOOKUP_FIELD") {
        if(spjs.vLookup.dataObj[fin][spjs.dffs.data.thisItemID].count > 0){
            jQuery("#dffs_" + fin).find("#newItemWrap_" + fin).hide(); 
        }
    }
}

Replace NAME_OF_YOUR_VLOOKUP_FIELD with the correct field name.

Just tested hiding the vlookup button. Brilliant!

[Leonid]

Thanks Alex, I will try that! What is the best event to add the code in New form to ensure it fires right after the Child item created?

Followup questions:
I need multiple associations: whats the naming rule for _vLookupID? e.g. _vLookupID1, _vLookupID2, etc.

Do I understand correctly that if I use regular item IDs those wont work in Edit form to show proper relationship between Parent and Child. Thus OOB lookup wont work

[Alexander Bautz]

Hi,
This function does not have the field name as an argument, but we have the field name in a variable and can use it like this:

function vlookupChildAddedCallback() {
    switch (spjs.vLookup.data.refreshThisField) {
        case "vLookup_field1":
            // Do something for vLookup_field1
        break;
        case "vLookup_field2":
            // Do something for vLookup_field2
        break;
    }
}

I’m not sure I understand your last sentence – can you clarify?

Alexander

[Leonid]

Thanks Alex! To clarify vlookupChildAddedCallback(): Im using folders with vLookup. CAML query should have a recursive scope to go through the folders (?). How this can be accomplished with

spjs.utility.queryItems

[Alexander Bautz]

Add “scope” like this:

var res = spjs.utility.queryItems({
    "listName": "DISPLAY_NAME_OF_CHILD_LIST",
    "query": "<Where><Eq><FieldRef Name='_vLookupParentID' /><Value Type='Text'>" + getFieldValue("_vLookupID") + "</Value></Eq></Where><OrderBy><FieldRef Name='ID' Ascending='FALSE' /></OrderBy>",
    "rowLimit": 1,
    "viewFields": ["ID"],
    "scope":"RecursiveAll"
});

Alexander

[Leonid]

That worked like a charm!

Im facing sort of rendering issue with multiple vLookups. Sometimes only 1st button shows up. 2nd vlookup button will show if I click the one shown and then close the dialogue

Not sure what could cause this – do you have any custom css or js to hide this button? – if not, try hitting f12 to bring up the developer console and see if you have any errors there.

Alexander

[Leonid]

Alex,
The button visibility is driven only by the Rule on the dropdown.

[Alexander Bautz]

Not sure I follow, please show me some screenshots of your current code and corresponding rules.

Alexander

[Leonid]

The only function related to vLookup is:
`function vlookupChildAddedCallback(){
var res = spjs.utility.queryItems({
“listName”: “LCR Answers”,
“query”: “<Where><And><Eq><FieldRef Name=’_vLookupParentID’ /><Value Type=’Text’>” + getFieldValue(“_vLookupID”) +
“</Value></Eq><Contains><FieldRef Name=’FileRef’ /><Value Type=’Text’>” + LCR_ID +
“</Value></Contains></And></Where><OrderBy><FieldRef Name=’ID’ Ascending=’FALSE’ /></OrderBy>”,
“rowLimit”: 1,
“viewFields”: [‘ID’, ‘Title’, ‘FileRef’],
“scope”:”RecursiveAll”
});
if(res.count > 0){
//debugger;
var id = res.items[0].ID;
var title = res.items[0].Title;
setFieldValue(title.replace(” “, “”) + “ID”, id);
}
}

and the rule is attached

Ah, I think this is a bug related to the field being hidden initially when the tab is rendered. The vLookup field is only initiated if the field is visible and it looks like it does not initiate correctly when being made visible by a rule. I’ll look into this and see if there is something I can do to fix it in the next release. In the meantime you might consider just leaving the field visible.

Alexander

[Leonid]

Got it. I will set the field visible and hide it on form loaded instead. Hope that will work

[Leonid]

Alex, the other question came up. I copied vLookup settings from New to Edit form.
Prefill values in child works fine in the New form, but doesnt in the Edit form. Is there some settings that should be adjusted?

[Alexander Bautz]

If you create a new child item from the parent items EditForm it should still prefill values in the child item NewForm. Can you show me a screenshot of your config and also note what field types you are trying to set.

Alexander

[Alexander Bautz]

Hi Leonid,
I tried to recreate the problem with the vLookup field not rendering when you had it hidden in a rule initially, but could not get the same result as you.

As soon as the choice is selected (and the rule is evaluated to true) the vLookup field shows as it should.

Which version of DFFS are you running (hover over the Enhanced with DFFS below the form and click the License and version information link)?

Alexander

[Leonid]

Alex, Im emailing snapshots and vLookup config to your gmail.
Im running 4.4.4.23 DFFS Loader with 1.1.19 Lookup

[Leonid]

Any luck in pointing me to right direction?

[Alexander Bautz]

Sorry for the late reply. I looked at the screenshots and cannot see anything that could cause he button to now show.

I cannot remember to have fixed this explicitly, but if you are able to update to the latest version and test it it would help me trying to sort out the problem.

Alexander

[Leonid]

Alex,
The issue is with vlookup: fields not pre-filling in the Edit form whereas they prefill in the New form, same configuration

• This reply was modified 4 years, 3 months ago by Leonid.

[Alexander Bautz]

Ah, sorry about that. Unfortunately I don’t see anything that could cause the form to not prefill when adding a child item from EditForm. Do you see any error messages if you open the developer console (hit f12 > console)?

Also, is there any difference if you test it in another browser?

Alexander

[Leonid]

I posted 2 replies and none made it to this thread

[Alexander Bautz]

The two comments were interpreted as spam and filtered out. I deleted them now that you got it working.

PS: I looked at the errors and it didn’t really tell me anything other that that there was an error in the spellcheck in a rich text field.

Alexander

[Leonid]

I redid the whole thing with new lists and sofar prefill is working

[Leonid]

Alex,
For the snippet

function vlookupChildAddedCallback(){
    var res = spjs.utility.queryItems({
        "listName": "DISPLAY_NAME_OF_CHILD_LIST",
        "query": "<Where><Eq><FieldRef Name='_vLookupParentID' /><Value Type='Text'>"+getFieldValue("_vLookupID")+"</Value></Eq></Where><OrderBy><FieldRef Name='ID' Ascending='FALSE' /></OrderBy>",
        "rowLimit": 1,
        "viewFields": ["ID"]
    });
    if(res.count > 0){
        var newItemId = res.items[0].ID;
        setFieldValue("THE_FIELD_YOU_WANT_TO_SET", newItemId);
    }
}

Seems setFieldValue works only if SAVE button clicked on Edit form of the Parent item. Any way to set the field value w/o forcing user click Save?

[Alexander Bautz]

Sorry, but the only way to get the values saved in the parent is by manually saving it.

It is possible to write back and save it directly from the child item, but the you would get a save conflict when returning to the parent editform and trying to manually save it (because updating with code from the child makes a new version).
