react-table row selection with custom field instead of index - reactjs

I'm using the react-table package. I made a simple table with row selection. The problem is: The row selection result is an object with indexes:
{
0: true,
1: true,
...
}
But I want to be the primary key of my data like this:
{
EXoxMjyd4leYABdpuy8m: true,
2gXlClA38AU8sSM5jnZ7: true,
...
}
Code example
In the documentation, I can't find a configuration where I can set the selection key.
The question is, how can I achieve the second example?

You need to overwrite the table option getRowId.
Example:
const getRowId = (row, relativeIndex, parent) => {
// In row object you have access to data.
// You can choose parameter. In this example I used uniqueId
return parent ? [parent.id, row.uniqueId].join('.') : row.uniqueId;
}
Here is live example:

If you are using version 8 react-table; you can use instance.getSelectedRowModel() in order to get the original (data model of the rows) of the selected rows as well as the row indexes.
For instance:
const arraySelectedUsersId = instance.getSelectedRowModel().rows.map(({ original }) => (original as User).id)

Showing the new row in react-table on the current page

I have been playing with ReactTable v7 for a while and have encountered the following problem: when the table is sorted and uses paginator sometimes adding (or editing) a row causes it to be outside the current page.
You can see the problem here:
https://codesandbox.io/s/github/tannerlinsley/react-table/tree/master/examples/material-UI-kitchen-sink
Sort the table by First Name
Press add
Enter a record with First Name "zzzzz"
The record is added but is currently hidden which confuses users.
Is there a "standard" way to fix the issue? Am I missing something?
In v6 I have done a workaround for it:
React.useEffect(() => {
if (editedElementId && reactTable) {
const { data } = reactTable.props;
if (data && data.length > 0) {
const internal = reactTable.getResolvedState();
let position = -1;
internal.sortedData.forEach((row, i) => {
if (row._original.id === editedElementId) position = i;
});
if (position >= 0) {
const pageNumber = Math.floor(position / pageSize);
setPage(pageNumber);
} else {
alert.info("Element not visible");
}
}
}
}, [editedElementId]);
...
<ReactTable
ref={(r) => {setReactTable(r);}}
...
But maybe there is a bulit-in way to achieve it?
There is not currently a way to only sort the elements which are currently being displayed, no.
React Table v7's useSortBy hook sorts the entirety of the input data array, so sorting by First Name descending (A->Z) naturally places 'ZZZZZZ' at the end of the list, which will be hidden due to pagination. The v7 way of doing it would probably be similar to what you are doing already, using the exposed properties from the useTable hook instead of reactTable.resolvedState() and etc. Another way to do it would be to write your own custom sortBy method and only sort the items [0...n] where n is the number of currently displayed items.
As a side note, since the autoResetSortBy property is true by default in the example you linked, the step of sorting on First Name is irrelevant -- since the function which adds a new user to the list mutates the data array, the sorting method is reset. That function appends the new user to the end of the list, so it will always be on a new page, even if the "Rows per page" option is set to "All". Both issues can be fixed by setting autoResetSortBy to false, and changing the pageSize in addUserHandler.

How to get column index on Cell Click event in ag-grid?

I think of simplifying the click events and instead of attach them on column renderer (I use React), I tried to attach a single onCellClicked event (where I do get all the data for the row) and do a switch for... column. On first column there will be a delete button, on second something else, etc. I do have some colDef and column, but no index for the column. Instead I have a colId, which isn't what I need. I do have a colDef, where column header could be used, but for my case I don't have headers. I can't imagine how they omitted the column index.
You can get all columns and find its index based on the field property if you don't provide the colId:
<AgGridReact
{...}
onCellClicked={(e) => {
const field = e.colDef.field;
const colIndex = e.columnApi
.getAllColumns()
?.findIndex((col) => col.getColDef().field === field);
console.log(field, colIndex);
}}
/>

How to update autoGroupColumnDef property of ag-Grid after table is initialized

I have an ag-grid table (Enterprise version: 22.1.0) which is grouped using autoGroupColumnDef property. The grouping is dependent on the table's data and the data loads on a button click. I need to update the autoGroupColumnDef property's field name (_this.colName in the below code) after the page is loaded, right before loading the data.
Table's grid options:
_this.gridOptions = {
defaultColDef: {
sortable: true,
resizable: true,
filter: true
},
columnDefs: _this.columnDefs,
rowData: [],
enableRangeSelection: true,
autoGroupColumnDef: {
headerName: "Sector",
field: _this.colName,
cellRendererParams: {
suppressCount: true
},
tooltipValueGetter: function(params) {
return _this.tooltipVal
}
},
suppressAggFuncInHeader: true,
enableBrowserTooltips: true
};
I update the variable _this.colName before setting data to the grid. I have tried the following options and none of them worked for me:
_this.gridOptions.api.refreshClientSideRowModel('group');
_this.gridOptions.api.refreshCells();
_this.gridOptions.autoGroupColumnDef.field = 'Column's Name'
Any help would be appreciated!
There is a good workaround for this. You can set autoGroupColumnDef, then remove and readd all row groupings. It will redraw the group column with the new name.
gridOptions.autoGroupColumnDef.headerName = 'new_name';
// Get current groupings
var colstate = gridOptions.columnApi.getColumnState();
var colstateclear = gridOptions.columnApi.getColumnState();
// Clear groupings
var x = 0, xcount = colstateclear.length;
while ( x < xcount ) {
colstateclear[x].rowGroupIndex = null;
x += 1;
}
gridOptions.columnApi.setColumnState(colstateclear);
// Reset groupings
gridOptions.columnApi.setColumnState(colstate);
I contacted ag-grid support and apparently this is a bug and they have it in their backlog with no ETA available for now. A workaround they provided was to use: https://www.ag-grid.com/javascript-grid-grouping/#showRowGroup.
This is not really a good workaround because the grouped columns are separated and makes the page feel cramped. Also there are some look and feel issues that keep popping up (Eg: empty space added before each column that increases with each grouped column. ie second column has 1 cm added before it, third column has 2 cm added before it and so on. I guess this was added to bring the grouped look in the group column but you wouldn't expect this behavior when the columns are separated.)
ag-grid's backlog ID for the ticket: AG-3359 - Allow the autoGroupColumn to be used in the API calls for columns, at the moment there is no way to dynamically change it after creation. (ie, setColumnDefs …)
Link to track the progress: https://www.ag-grid.com/ag-grid-pipeline/
there is a straight forward method to update the autoGroupColumnDef object and its properties with setAutoGroupColumnDef
this.gridOptions.api.setAutoGroupColumnDef(<ColDef>{
...this.gridOptions.autoGroupColumnDef, // preserve the other settings except the ones you need to change
minWidth: 500
})
if any problems with the spread operator,
do it manually:
this.gridOptions.api.setAutoGroupColumnDef(<ColDef>{
// ...this.gridOptions.autoGroupColumnDef, // preserve the other settings except the ones you need to change
headerName: this.gridOptions.autoGroupColumnDef.headerName,
minWidth: 500
})
and one more thing, add this if you have any visual bugs, like: header row gets resized but bellow rows stays the same as previus state, so the refresh of model is required:
this.gridOptions.api.refreshClientSideRowModel();
this refresh is not ideal solution, because it refreshes everything, so you will loose expanded levels for example, still no clue how to preserve all settings.
https://angulargrid.com/angular-grid/client-side-model/#refreshing-the-client-side-model
and best solution for now is tu use:
this.gridOptions.api.redrawRows();
it keeps the rows expanded if are, checkbox selected if is.

Sort an array of objects based on another array of objects in angular 7

I know it's been asked million+1 times. But i've found no help in those questions/answers.
I have 2 arrays of 2 different objects one string property is used to uniquely identify them. This would be the key to sort about, but said object prop names are not equal (accessValue, modifiedOption). But their values are!
Object1: { ... accessValue, ... };
Object2: { ..., modifiedOption, ... };
array1:Object1[];
array2:Object2[];
I'd like to sort array1 based on the object indencies of array2.
So all of array1 items'd be in the same order as array2.
These two arrays are used to model a connected dropdown selection system, which can be added to are removed from. The Addition is screwing me over (lastly added item is appended to the first place and not the last) probably because of filter below?
What I use to add new dropdowns:
addFieldRow() {
this.fieldRows.push(0); // since desired selection is not known yet but need to populate the array that represents the 1st selection so a 2nd main selection dropdown will appear on screen
...
}
public onSelect() {
// if a selection is happened check the values of editOptions (contains data about all main selectable options)
this.fieldRows = this.editOptions.filter(
option => this.selectedOptions.some(el => el.modifiedOption === option.accessValue)
);
this.disableSelected(); // disable already selected items (not related to my issue)
this.optionSelected = true; // this is just for button disabled toggle
}
So either i need to figure out my addRow logic (if it has any flaws) or implement a sorting utility to make sure that the objects of fieldRows are in the same order as selectedOptions' -> since this models the selection directly.
I cannot really add a stackblitz since it's hard to model my current state.
Okay I am a complete idiot!
Since I know the current index (since i am looping through fieldRows).
All I had to do is replace this:
public onSelect() {
this.fieldRows = this.editOptions.filter(
option => this.selectedOptions.some(el => el.modifiedOption === option.accessValue)
);
With this:
public onSelect(index) {
this.fieldRows[index] = this.editOptions.find(option => this.selectedOptions[index].modifiedOption === option.accessValue);
this.disableSelected();
this.optionSelected = true;
}
Now it works correctly.

extjs adding additional field to dynamic forms

I need to allow my users to submit multiple property addresses by clicking a button that will insert a fieldset with extra text fields. I can do this simply with form.insert(index, component); However, that index will change after the user adds an additional property. For example, the index to add the extra properties is after the 7th component, making the index 7. But when you insert it at 7, it's index is now 7 and the next property will be inserted above it. This effect is further compounded when you try to do this with contact emails and numbers in the same form. So my question is, how can I get the index of the component in the form that I wish to insert the extra fields after?
fieldset.items.getCount()
Or am I missing something?
not exactly straight forward, but not too bad either. take a look at the following code: the first part is the button handler to add a set of fields, the second is the actual function that creates the indexed fields.
handler:function () {
var parts = this.up('fieldset'),
index = parts.query('fieldcontainer').length, //calculate existing Part line items
fields = this.up('window').createPartFieldContainer(index);
parts.add(fields);
}
createPartFieldContainer:function (index) {
index = index || 0;
return {
xtype:'fieldcontainer',
items:[
{
xtype:'textfield', fieldLabel:'Item',
name:'lineItem[' + index + '].itemNumber', width:100,
emptyText:'Part Number'
}
]
}
}
