I'm trialling HandsOnTable via the Vue wrapper to make a simple database editor. I can populate the table easily, however I now need to save changes back to the database.
If I use the afterChange() method hot will give me the changes in the cells that have changed, however I need to be able to associate those changes with a database id to send them back to the server. Any idea of how to do this, and also is it possible to get the changes associated with a row? Would it also be possible to do this without displaying the database id to the user in the table?
To answer your main question, you can associate metadatas to cells. So you can put your technical id in your first column for example or a hidden column (or whereever you want).
hot.setCellMeta(0, 0, 'myIdName', 'myIdValue');
where "hot" is your Handsontable instance. (documentation reference)
You can then access getCellMeta(0, 0).
Second question :
and also is it possible to get the changes associated with a row ?
You already are able to get the changes of specific rows by filter the changes in the afterChange hook. Taking the example from Handsontable documentation this is how you get the row :
new Handsontable(element, {
afterChange: (changes) => {
changes.forEach(([row, prop, oldValue, newValue]) => {
// Some logic...
});
}
})
As you can see changes is an array of change that contain row and col (prop).
Hope this helps.

I'm building a PowerApps app on Azure SQL
The requirement
I have a form which has "Save" and "Confirm" buttons.
Both buttons should save the form data. The Commit button should also set database column "Confirm" to 1
I've read at length about how I can programatically override the update value of a hidden control for this. But I'm not satisfied with the level of complexity (maintenance) required to get this working, i.e.
Populate a variable with the current db value
In the button code set the variable value
In the form field, set the update property to the variable
What I'm Trying
So I'm trying a different approach: SubmitForm then Patch. Even though this requires an extra database call, I'd like to understand if this will work. This is the code for OnSelect in the commit button:
// Save the record
SubmitForm(frmEdit);
// Update confirmed to 1
Patch('[dbo].[Comments]',cRecord,{Confirmed:1});
Some Complexities
Note that my record is a variable, cRecord. In short I want this app to be able to upsert based on URL parameters.
This is my App.OnStart which captures URL values, inserts a record if required. Regardless, the result of this event is that cRecord is set to the record to be edited.
// Cache employees and store lookups (as they are in a different db)
Concurrent(Collect(cEmployees, Filter('[dbo].[SalesPerson]', Status = "A")),Collect(cStores, '[dbo].[Store]'));
// Check for parameters in the URL. If found, set to Edit/Add mode
Set(bURLRecord,If((!IsBlank(Param("PersonId")) && !IsBlank(Param("Date"))),true,false));
// If URL Parameters were passed, create the record if it doesn't exist
If(bURLRecord,
Set(pPersonId,Value(Param("PersonId")));
Set(pDate,DateValue(Param("Date")));
// Try and find the record
Set(cRecord,LookUp('[dbo].[Comments]',SalesPersonId=pPersonId && TransactionDate = pDate));
If(IsBlank(cRecord),
// If the record doesn't exist, create it with Patch and capture the resulting record
Set(cRecord,Patch('[dbo].[Comments]',Defaults('[dbo].[Comments]'),{SalesPersonId:pPersonId,TransactionDate:pDate}))
);
// Navigate to the data entry screen. This screen uses cRecord as its item
Navigate(scrEdit);
)
frmEdit.Item is set to cRecord. As an aside I also have a gallery that sets this variable value when clicked so we can also navigate here from a gallery.
The navigating using new and existing URL parameters works. Navigating from the gallery works.
The problem
When I press the Commit button against a record which has Confirmed=0 I get this popup error:
The data returned by the service is invalid
When I run this code against a record which already has Confirmed=1 I don't get an error
If I run the PowerApps monitor it doesn't show any errors but it does show some counts being run after the update. I can paste it here if required.
I also tried wrapping the Path in a Set in case it's result was confusing the button event but it didn't make a difference.
What I want
So can anyone offer me any of the following info:
How can I get more info about "The data returned by the service is invalid"?
How can I get this to run without erroring?
Is there a simpler way to do the initial upsert? I was hoping a function called Patch could upsert in one call but it seems it can't
With regards to the setting field beforehand approach, I'm happy to try this again but I had some issues implementing it - understanding which control where to edit.
Any assistance appreciated.
Edit
As per recommendations in the answer, I moved the patch code into OnSuccess
If(Confirmed=1,Patch('[dbo].[CoachingComments]',cRecord,{Confirmed:1}));
But now I get the same error there. Worse I cleared out OnSucces and just put SubmitForm(frmEdit); into the OnSelect event and it is saving data but still saying
The data returned by the service was invalid
First things first,
Refactoring has multiple steps,
I can t type all out at once...
The submitform and patch issue:
Never use the submitforn with extra conplexity
Submitform is only the trigger to send the form out,
The form handler will work with your data...
If you hsven t filled out the form correctly, u don t want to trigger your patch action...
So:
On your form, you have an OnSucces property,
Place your patch code there...
Change your cRecord in your patch statement:
YourForm.LastSubmit
Apologies in advance, I'm new to relay and not sure I've got all the terminology here right...
I have a (simplified) graph that looks like:
customer {
summary(id: "ABC123") {
records { // This is an array of Record
tag
}
}
}
Customer, Summary and Record are all objects with global IDs - they show up as records in the Relay DevTools inspector.
I have a mutation that removes a tag by name (from elsewhere in the graph - not shown), from which I need to update the customer summary object to remove the record with associated tag. I have tried two approaches and not gotten very far with either:
Re-request customer.summary as part of the mutation. The problem is I don't know what the ID is at that point. (Maybe I can thread it through some how, but that would be messy.) Also doesn't really solve the problem, since I'd like to do this optimistically.
In an optimistic updater, remove any tag record that matches. This seems like it should work, but the RecordProxy doesn't appear to have a rich enough API to enable me to do this.
First approach, I can't seem to get access to the summary record via the root:
const customer = store.getRoot().getLinkedRecord('customer') // works!
customer.getLinkedRecord("summary") // undefined
customer.getLinkedRecord("summary", {id: "ABC123"}) // undefined
Second approach, if I could ask the store for "all records of type" or even "all records" I could iterate through and find the one I need to edit, but this doesn't seem to be a method that's exposed (even though Relay DevTools must be doing it somehow).
I have a situation where i'd like to enter a "3" into a textbox on a user story grid, call something like RankToPosition(3) to move that user story row to position 3 in the current rank. Within the same grid, the idea is to have a textbox on each row, so the row beneath may have a 4 in there, and when i click SUBMIT, the entire table would be processed by using the numbers in the row textbox and calling RankToPosition(#). This is like the Netflix queue. There have been similar questions on here, but my thought is to just call the underlying method alluded to here as "_onMoveToPositionClicked":
https://help.rallydev.com/apps/2.0rc3/doc/source/MoveToPositionMenuItem.html#Rally-ui-menu-item-MoveToPositionMenuItem-cfg-rankRecordHelper
If i could iterate through the table grid, store initial rank values (i realize they're not just integers), and pick the new text values up, run code to call the _onMoveToPositionClicked beneath the scenes, it may accomplish a bulk rank grid for when users have 200+ items to manage, for instance.
Any insight you have for just calling this in custom code would be helpful. Any solution for representing this functionality would be appreciated. I am currently using Rally 2.0rc3.
Thank you for your time
Is it possible to upgrade to a newer version of the App SDK? 2.0rc3 is a very old pre-release. The latest is 2.1: https://help.rallydev.com/apps/2.1/doc/
In any case, the way ranking is performed is relative to another object via the rankAbove or rankBelow parameters. So given the record you want to rerank:
record.save({
params: {
rankAbove: '/hierarchicalrequirement/12345'
}
});
I have a table driven by DataTables 1.10. Filtering is turned on. When I talk about "doing a search" below, I'm talking about using the filtering function of this table.
Description of the Problem
Everything works fine with stateSave off. However, when stateSave is on, the following happens:
Alice logs in as admin. Because admin has all privileges, when she does a search through articles, she can see all articles. Because some articles are published and some are unpublished the table has a column that show which are published and which are not. So far so good.
Bob, a random user, accesses the site. Random users cannot ever see unpublished articles so the table hides the column that shows publication status. So far so good.
Alice logs out. She now accesses the site like a random user. So she should see exactly what Bob sees. However, when she does a search she still sees the column that indicates publication status.
(Note: The issue I'm discussing here is purely one of user interface. The server ensures that unprivileged users cannot ever get a record for an unpublished article. The problem though is that the additional column gives unpriviledged users information that they do not need. They can only see published articles in their search so they don't need to see that every article they get in a search is published.)
The code that configures the datatable hides the publication column by doing something like this:
var columnDefs = [];
if (!privileged) {
columnDefs.push({
targets: [1],
orderable: false,
visible: false
});
}
columnDefs is passed to DataTables as the columnDefs option.
Technical Reason for the Problem
The problem is that DataTables store things like column visibility into the state it saves into localStorage. So when Alice logs out and makes a search again as an unprivileged user, even though the value of columnDefs is correct, it is overwritten by the saved state. That state was stored when Alice was an admin, and it declared the publication column to be visible, so it remains visible even when Alice is accessing the site as an unprivileged user.
What I want is for users to benefit from the saved state but avoid having this state carry over when the user's privileges change.
Caveats:
I don't want to use sessionStorage because I want the state to persist between browser closings, but sessionStorage is cleared when the browser is closed.
I cannot use the session cookie assigned by the server to detect logins and logouts because it is HTTP only. Besides, privileges could change for other reasons.
I do not want to arbitrarily set an expiration time on the saved state.
The solution I've settled on is to use an additional field in the saved data to know when the conditions I care about have changed. This is a field whose value changes depending on the privileges that the user currently has. For instance, because in the case I described here, I decide to hide or show a column on the basis of a variable named priviledged (which is initialized from data provided by the server), it could be as simple as:
var token = privileged;
Then I set stateSaveParams to record the token when the state is saved:
stateSaveParams: function (settings, data) {
data.myapp_token = token;
}
The prefix myapp_ is just there to avoid possible collisions with DataTable's own fields.
I set stateLoadParams so that if the current value of token differs from what has been recorded before, the state is cleared:
stateLoadParams: function (settings, data) {
if (data.myapp_token !== token) {
this.api().state.clear(); // Clears the state.
return false; // Tells DataTables to not use the state that was stored.
}
// This return is here to keep the IDE happy but does not do anything special.
return undefined;
},
I've just set token to the single condition I've shown in my question (privileged) in this example but in production I use a combination of variables plus a local version number so I can bump the value of token as needed if I do something that requires clearing the state but cannot be detected just as a privilege change.
I have a ruby script that is trying to pull up some custom fields from Rally, the filter works just fine ( the filter contains one of the custom fields i want to pull up) but when I try to display it, it doesn't show up in the list (the value returned for all custom fields is blank, while appropriate values are returned for FormattedID, Name, Description).
Here's the link [link]http://pastebin.ubuntu.com/6124958/
Please see this post.
Do you fetch the fields?
What version of WS API are you using? If it is v2.0 is c_ prepended to the name of the field in the code?
How is the field spelled in your code and how that spelling compares to Name and Display Name of the field in UI?
There is another reason why custom fields might not appear (other than the versioning and 'c_' issues nickm mentioned). I just found this out after a ton of head banging. The Rally SDK's ui stuff will filter out all fields that are hidden (such as _ref, or other 'hidden' custom fields) so you cannot view them in your apps in grids, charts, etc. For example, when constructing a Rally.ui.grid.Grid, a class called Rally.ui.grid.ColumnBuilder is constructed and it executes a command on the columns of the chart that look like this:
_removeHiddenColumns: function (columns) {
return _.filter(columns, function (column) {
return !column.modelField || !column.modelField.hidden;
});
},
As you can see, if you try to display any fields that are hidden (like _ref for example) in a grid, the column gets removed. So, although you may be fetching the custom fields, they will not show up unless those fields are not 'hidden'.
