I'm tasked with moving some UI-Grids to AG-Grid.
I need to allow the user to use a space delimited string for a column filter so "1 4 23 88" would return all rows where column has 1 or 4 or 23 or 88 as a value.
AG-Grid has the drop down OR option but is added clicks and only allows two values.
With UI-Grid the filter parameter in columnDefs can have a condition:
filter:{condition: filterFunction}
FilterFunction simply has the custom logic and returned true or false.
Is there something similar with AG-Grid? Reading through the docs it seems to get overly involved to create a custom filter. The UI-Grid solution is like 6 lines of code.
CentOS 7, VueJS
I ended up using:
filter:'agTextColumnFilter', filterParams: {textCustomComparator: this.filterFunction}
With filterFunction holding the logic.
https://www.ag-grid.com/javascript-grid/filter-text/#text-custom-comparator
Though I'm using a number column there is not a comparator filterParam for numbers, only 'comparator' for dates and 'textCustomComparator' for text.
This seems to work fine for what I need.

Filtering by a second column removes the filter from the first column, Ag Grid, Vue. How can it be avoided?
I would like to be able to filter by more than one column.
I am using the server side rendering. I found out the framework code which is responsible for checking if there is a filter applied (and if this code piece tells that a filter is not applied, then the respective filter gets removed):
SetValueModel.prototype.isFilterActive = function () {
return this.filterParams.defaultToNothingSelected ?
this.selectedValues.size > 0 :
this.allValues.length !== this.selectedValues.size;
};
In my case I did not set the defaultToNothingSelected, it is undefined, so it results in a falsy value. But since I update my set filter values after running the filter, the this.allValues.length becomes equal to the this.selectedValues.size, which results in the isFilterActive returning false.
So far the two solutions I see are to either set the defaultToNothingSelected to true or do not remove the available filter values after the filtering was done. I remove them using the api.getFilterInstance(colId).setFilterValues(values).
By removing the filter values I mean the following:
A column has the a, b and c values. I filter by a. Now I set the available filter values to be only a. Probably I should not be doing that.
I still hope to find a cleaner solution, so let the question hang here.
I am currently facing a Regex problem which apparently I cannot find an answer to.
My Regex is embedded in a teradata SQL of the form:
REGEXP_SUBSTR(column, 'regex_pattern')
I want to find the first appearance of any number except if it appears at the end of the string.
For Example:
"YEL2X30" -> "2"
"YEL19XYZ05" -> "19"
"YELLOW05" -> ""
I tried it with '[0-9]+(?!$)/' but this returns me a blank String always.
Thanks in Advance!
Shot in the dark here since I'm unfamiliar with teradata and the supported SQL-functionality. However, reading the docs on the REGEXP_SUBSTR() function it seems like you may want to use the 3rd and 4th possible argument along with a slightly different regular expression:
[0-9]+(?![0-9]|$)
Meaning: 1+ Digits that are not followed by either the end of the string or another digit.
I'd believe the following syntax may work now to retrieve the 1st appearance of any number from the matching results:
REGEXP_SUBSTR(column, '[0-9]+(?![0-9]|$)', 1, 1)
The 3rd parameter states from which position in the source-string we need to start searching whereas the 4th will return the 1st match from any possible multiple matches (is how I read the docs). For example: abc123def456ghi789 whould return 123.
Fiddling around in online IDE's gave me that:
CREATE TABLE TBL (TST varchar(100));
INSERT INTO TBL values ('YEL2X30'), ('YEL19XYZ05'), ('YELLOW05'), ('abc123def456ghi789');
SELECT REGEXP_SUBSTR(TST, '[0-9]+(?![0-9]|$)', 1, 1) as 'RESULTS' FROM TBL;
Resulted in:
RESULTS
2
19
NULL
123
NOTE: I also noticed that leaving out the 3rd and 4th parameter made no difference since they will default back to 1 without explicitly mentioning them. I tested this over here.
Possibly the simplest way is to look for digits followed by a non-digit. Then keep all the digits:
regexp_substr(regexp_substr(column, '[0-9]+[^0-9]'), '[0-9]+')
This may be something really simple, but I couldn't figure it out and been trying to find an example online to no avail. I'm basically trying to remove items found in one sequence from another sequence.
Example #1
Items added to the cart is in one sequence; items removed from cart is in another sequence:
<#assign Added_Items_to_Cart = "AAAA,BBBB,CCCC,DDDD,EEEE,FFFF">
<#assign Deleted_Items_from_Cart = "BBBB,DDDD">
The result I'm looking for is: AAAA,CCCC,EEEE,FFFF
Example #2
What if the all items added to and deleted from cart are in the same sequence?
<#assign Cart_Activity = "AAAA,BBBB,BBBB,CCCC,DDDD,EEEE,DDDD,FFFF,Add,Add,Delete,Add,Add,Add,Delete,Add">
The result I'm looking for is the same: AAAA,CCCC,EEEE,FFFF
First things first: You ask about sequence but the data you are dealing with are strings.
I know you are using the string to work as a sequence (and it works), but sequences are sequences and strings are strings, and they have diferente ways of dealing with. I just felt this was important to clarify if someone who is starting to learn how to program get to this answer.
Some assumptions since you're providing strings with data separated by comma:
You want a string with data separated by comma as a result.
You know how to properly create strings with data separated by comma.
You dont have commas in your items names.
Observations:
I'll give you the logic but not the code donne, as this can be a great chance for you to learn/practice freemarker (stackoverflow spirit, you know...)
You question is not about something specific of freemaker (it just happens to be the language you want to work with). Think about adding the logic tag to you question. :-)
Now to the answer on how to do what you want on a "string that is working as a sequence":
Example #1
Change your string to a real sequence :-)
1 - Use a built-in to split your string on commas. Do it for both Added_Items_to_Cart and Deleted_Items_from_Cart. Now you have two real sequences to work with.
2 - Create a new string tha twill be your result .
3 - Iterate over the sequence of added itens.
4 - For each item of the added list, you will check if the deleted list also contains this item.
4.1 - If the deleted list contains the item you do nothing.
4.2 - If the deleted list do not contains the item, you add that item to your string result
At the end of this nested iteration (thats another hint) you should get the result you're looking for.
Example #2
There are many ways of doing it and i'll just share the one that pops out of my mind right now.
I think it's noteworthy that in this approach you will always have an even sized list, as you always insert 2 infos each time: item and action.
So always the first half will be the 'item list' and the second half will be the 'action list'.
1 - Change that string to a sequence (yes, like on the other example).
2 - Get half of its size (in your example size = 16 so half of it is 8)
3 - Iterate over a range from 0 to half-1 (in your example 0 to 7)
4 - At each iteration you'll have a number. Lets call it num (yes I'm very creative):
4.1 - If at the position num + half you have the word "Add" you add the item of position num in your result string
4.2 - If at the position num + half you have the word "Delete" you remove the item of position num from your result string

The list starts empty. Then I want to append an value to it for each iteration in a loop if certain condition is met. I don't see append option in Variable Operation.
You can use string split for this, assuming you know of a delimiter that won't ever be in your list of values. I've used a semi-colon, and $local_joinedList$ starts off empty.
If (certain condition is met)
Variable Operation: $local_joinedList$;$local_newValue$ To $local_joinedList$
End If
String Operation: Split "$local_joinedList$" with delimiter ";" and assign output to $my-list-variable$
This overwrites $my-list-variable$.
If you need to append to an existing list, you can do it the same way by using String Join first, append your values to the string, then split it again afterward.
String Operation: Join elements of "$my-list-variable$" by delimiter ";" and assign output to $local_joinedList$
Lists are buggy in Automation Anywhere and have been buggy for several versions. I suggest not using them and instead use XML.
It it a much more versatile approach and allows you to do much more that with lists. You can search, filter, insert, delete etc.
For the example you mention, you would use the "Insert Node" command.
Throwing in my 2 cents as well - my-list-variable appears to be the only mutable in size list you can work with. From my experience with 10.7, it only grows though.
So if you made a list with 60 values, and you wanted to use my-list-variable again for 55, you'll need to clear out those remaining 5 values and create an if condition when looping over the list to ensure the values are not whatever you set those 5 values to be.
I used lime's answer as a reference (thanks lime!) to populate a list variable from some data in an Excel spreadsheet.
Here's my automation for it:
I would like to ask you if you could please explain the anatomy of the Openerp domain filters. I have to use it my project.
Please explain the description of the following domain filter.
['|',('order_id.user_id','=',user.id),('order_id.user_id','=',False)]
I want to know the exact meaning of (order_id.user_id','=',user.id), what is order_id, user_id, and user.id. Are they referencing any table. If yes then how am I supposed to know which one...
Basically I want to know decipher the notation from bottom up so that can use it as per my requirement.
This one is pretty simple.
Consider the following fields (only XML i've given here, python you got to manage)
<field name="a"/>
<field name="b"/>
<field name="c"/>
Single Condition
Consider some simple conditions in programming
if a = 5 # where a is the variable and 5 is the value
In Open ERP domain filter it would be written this way
[('a','=',5)] # where a should be a field in the model and 5 will be the value
So the syntax we derive is
('field_name', 'operator', value)
Now let's try to apply another field in place of static value 5
[('a','=',b)] # where a and b should be the fields in the model
In the above you've to note that first variable a is enclosed with single quotes whereas the value b is not. The variable to be compared will be always first and will be enclosed with single quotes and the value will be just the field name. But if you want to compare variable a with the value 'b' you've to do the below
[('a','=','b')] # where only a is the field name and b is the value (field b's value will not be taken for comparison in this case)
Condition AND
In Programming
if a = 5 and b = 10
In Open ERP domain filter
[('a','=',5),('b','=',10)]
Note that if you don't specify any condition at the beginning and condition will be applied. If you want to replace static values you can simply remove the 5 and give the field name (strictly without quotes)
[('a','=',c),('b','=',c)]
Condition OR
In Programming
if a = 5 or b = 10
In Open ERP domain filter
['|',('a','=',5),('b','=',10)]
Note that the , indicates that it's and condition. If you want to replace fields you can simply remove the 5 and give the field name (strictly without quotes)
Multiple Conditions
In Programming
if a = 5 or (b != 10 and c = 12)
In Open ERP domain filter
['|',('a','=',5),('&',('b','!=',10),('c','=',12))]
Also this post from Arya will be greatly helpful to you. Cheers!!
The '|' is an OR that gets applied to the next comparison. The (..., '=', False) gets converted into an IS NULL so the SQL for this would be
WHERE order_id.user_id = x OR order_id.user_id is NULL
The default is AND which is why you don't see ('&', ('field1', '=' ,1), ('field2' ,'=', 2) everywhere.
Note that another useful one is ('field1', '!=', False) which gets converted to WHERE field1 IS NOT NULL
There isn't a lot of great documentation for this and they get quite tricky with multiple operators as you have to work through the tuples in reverse consuming the operators. I find I use complex ones infrequently enough that I just turn on query logging in Postgres and use trial and error observing the generated queries until I get it right.
