The dgrid Editor is a column-level plugins, which controls the whole column behavior.
Suppose I have a list of parameters, each has different value type that I want to show in different widgets. For example:
param1 value1(bool, shown as a checkbox)
param2 value2(string, shown as a text input)
param3 value3(enum, shown as a combobox)
param4 value4(int, shown as a NumberSpinner)
....
All the values are in the second column in the dgrid, but they are different types. How do I apply the Editor plugin to the cell level? Is there any method I can use to control individual cell in dgrid?
Thanks.

I have a list of data with a title column (among many other columns) and I have a Power BI parameter that has, for example, a value of "a,b,c". What I want to do is loop through the parameter's values and remove any rows that begin with those characters.
For example:
Title
a
b
c
d
Should become
Title
d
This comma separated list could have one value or it could have twenty. I know that I can turn the parameter into a list by using
parameterList = Text.Split(<parameter-name>,",")
but then I am unsure how to continue to use that to filter on. For one value I would just use
#"Filtered Rows" = Table.SelectRows(#"Table", each Text.StartsWith([key], <value-to-filter-on>))
but that only allows one value.
EDIT: I may have worded my original question poorly. The comma separated values in the parameterList can be any number of characters (e.g.: a,abcd,foo,bar) and I want to see if the value in [key] starts with that string of characters.
Try using List.Contains to check whether the starting character is in the parameter list.
each List.Contains(parameterList, Text.Start([key], 1)
Edit: Since you've changed the requirement, try this:
Table.SelectRows(
#"Table",
(C) => not List.AnyTrue(
List.Transform(
parameterList,
each Text.StartsWith(C[key], _)
)
)
)
For each row, this transforms the parameterList into a list of true/false values by checking if the current key starts with each text string in the list. If any are true, then List.AnyTrue returns true and we choose not to select that row.
Since you want to filter out all the values from the parameter, you can use something like:
= Table.SelectRows(#"Changed Type", each List.Contains(Parameter1,Text.Start([Title],1))=false)
Another way to do this would be to create a custom column in the table, which has the first character of title:
= Table.AddColumn(#"Changed Type", "FirstChar", each Text.Start([Title],1))
and then use this field in the filter step:
= Table.SelectRows(#"Added Custom", each List.Contains(Parameter1,[FirstChar])=false)
I tested this with a small sample set and it seems to be running fine. You can test both and see if it helps with the performance. If you are still facing performance issues, it would probably be easier if you can share the pbix file.
This seems to work fairly well:
= List.Select(Source[Title], each Text.Contains(Parameter1,Text.Start(_,1))=false)
Replace Source with the name of your table and Parameter1 with the name of your Parameter.
I wonder if I can create a query param that take multiple values from dropdown just like a non-typing combobox in the UI of ArangoDB. For example
//A route....
.queryParam('A', joi.any().allow(["true","false,"haha"]).required().default("true"))
The one above produce an dropdow that allow you to choose only 1 value. Is it possible to make them behave like a combo box on arango's UI?
I use this query param join's validation that shows as a drop down in the Arango UI
.queryParam('direction', joi.string().lowercase().valid('inbound', 'outbound', 'any')
.required().description('Direction of traversal from given product (inbound/outbound/any)'
))

PROBLEM: I need to extract the View Name from a Text field that contains a full SQL Statements so I can link the field a different data source. There are two text strings that always exist on both sides of the target view. I was hoping to use these as identifying "anchors" along with a substring to bring in the View Name text from between them.
EXAMPLE:
from v_mktg_dm.**VIEWNAME** as lead_sql
(UPPER CASE/BOLD is what I want to extract)
I tried using
SELECT
SUBSTR(SQL_FIELD,INSTR(SQL_FIELD,'FROM V_MKTG_TRM_DM.',19),20) AS PARSED_FIELD
FROM DATABASE.SQL_STORAGE_DATA
But am not getting good results -
Any help is appreciated
You can apply a Regular Expression:
RegExp_Substr_gpl(SQL_FIELD, '(v_mktg_dm\.)(.*?)( AS lead_sql)',1,1,'i',2)
This looks for the string between 'v_mktg_dm.' and ' AS lead_sql'.
RegExp_Substr_gpl is an undocumented variation of RegExp_Substr which simplifies the syntax for ignoring parts of the match
I'm using SPSS modeler and I have a variable that the software recognizes as numeric. So the missing values are $null$. I want that the missing values of the variable are selectionable with '', as character.
So I would: or trasform the format of the variable from numeric to character or change only the missing values from $null$ to ''.
How can I fix?
thanks in advance
The best way to select null values in a numeric field is to use the #NULL() function from the Blanks and Null section of the Expression Builder.
For example, if you wanted to keep only the null values so that you could inspect them, you might use a Select node. Leave the radio button set as Include. Press the Expression Builder (calculator) button. Change the filter in the drop menu on the left side from General Functions to show Blanks and Null (press B 2 or 3 times). Double-click on #NULL(ITEM). Go to the right side and double-click on your numeric field name. Put a Table node at the end and run it.
Using Select #NULL in IBM SPSS Modeler
Another way to view just the null rows is to enter the #NULL(varname) function into the "Highlight records where" section of the Table dialog box.
"Highlight records where" dialog
When you run the table, any row that is true for this condition will be shown in red.
If you really need the variable to be a string, then use a Compute node to create a copy of this field under a new name and use the to_string() function in the Conversion section of the Expression Builder to change the type of the variable. Now you will be able to use the the Select node to grab "" as the missing value. Or you could use the Filler node to replace the column, but then you would not be able to compare before and after.
The dialog examples shown in this answer use this sample stream that is installed with your IBM SPSS Modeler software:
C:\Program Files\IBM\SPSS\Modeler\18.0\Demos\streams\featureselection.str
The easiest way to do it it's using the Fill node with the configurations:
A) FIELD
B) Condition = #NULL(#FIELD)
C) Replace by = ' '
This node will replace all $null$ for ' ' at the same variable chosen in option a.
I don't think you can customize how you visualize $nulls. (I know it's possible in SQL db though)
So I'd suggest that you work with the numbers and when you want to visualize or export the results, then turn the field to a string one then replace nulls:
Filled node > to_string(#FIELD)
Filler node > blank and nulls > #FIELD = ''
Is there a way to use the Dynamic (Moded) Extended Choice Parameter to bind with an Extended Choice Parameter multi-level field to populate the first level's list?
For example if I had:
This would bind with this field below:
Either by having the first level (Choice) default with their ModedChoice selection (Choice1,Choice2,Choice3), or based on their ModedChoice selection 'Value1' would be populated (I would take the Choice level out in that case).
I know the second method I mentioned can be done for a single select list as described on the wiki and it would search for the text file Choice1.txt, Choice2.txt etc., which would contain Value1 values (i.e. key=value1.1,value1.2,value1.3 etc).
I couldn't figure out how to have that key contain a multi level list since it is a tab delimited format to separate columns, i.e:
Choice Value1 Value2
choice1 value1.1 value2.1
choice1 value1.1 value2.2
choice2 value1.2 value2.1
choice2 value1.1 value2.5
choice3 value1.2 value2.7
etc..
I tried something like (Choice1.txt):
key='Value1 Value2
value1.1 value2.1
value1.1 value2.2
value1.2 value2.1
value1.1 value2.5
value1.2 value2.7'
etc.. for Choice2.txt and Choice3.txt.
But this just populates the multi level with Value1 Value2.
I tried binding with another Moded Choice Parameter (Multi Select), and left the Key field empty and kept the proper tab delimited format for the multi level select list, but it still outputs Value1 Value2.
