有没有办法让用户输入附加到 spotfire 中的 table?

Is there a way to get user input appended to a table in spotfire?

我有一个 table Table1 在 spotfire (dcube) 中有一些上下文信息,它有类似的东西:

Name      Food    Seating
XYZ     Seafood   outdoors

我创建了一个带有两个按钮 YesNo 的测试区域。 用户将 select Table1 中的一条记录并单击其中一个按钮,它应该使用添加的列 Preference 填充另一个 table Table2输出如下:

Name      Food    Seating   Preference
XYZ     Seafood   outdoor     Yes

preference 列的值根据用户单击的是 Yes 还是 No 填充。当用户为 Table1 中的另一条记录设置首选项时,它应该作为行追加到 Table2.

是否可以通过 R 或 IronPython 而不使用 TERR?

您可以使用 python 并写回数据库来实现此目的。但是我不确定 good/efficient 在没有外部数据源的情况下如何做到这一点。

from Spotfire.Dxp.Data.Import import DatabaseDataSource
from Spotfire.Dxp.Data.Import import DatabaseDataSourceSettings
from Spotfire.Dxp.Application.Visuals import TablePlot
from Spotfire.Dxp.Application.Visuals import VisualTypeIdentifiers
from Spotfire.Dxp.Data import IndexSet
from Spotfire.Dxp.Data import RowSelection
from Spotfire.Dxp.Data import DataValueCursor
from Spotfire.Dxp.Data import DataSelection
from Spotfire.Dxp.Data import DataPropertyClass

rowCount = Document.ActiveDataTableReference.RowCount
rowsToInclude = IndexSet(rowCount,True)

#Get a cursor to the two columns we want to use. cursor1 is for the key column and cursor2 is for the column selected by the user input

cursor1 = DataValueCursor.Create[int](Document.ActiveDataTableReference.Columns["ProductID"])
cursor2 = DataValueCursor.CreateFormatted(Document.ActiveDataTableReference.Columns[whichCol])

#The following section will add a column to the database table using the name specified by the user. This assumes a column with this name does not already exist.

sqlCommand = "ALTER TABLE Products ADD " + colName + " varchar(50);"
dbsettings = DatabaseDataSourceSettings( "System.Data.SqlClient","Server=localhost;Database=myDB;UID=myuser;PWD=mypass",sqlCommand)
ds = DatabaseDataSource(dbsettings)
newDataTable = Document.Data.Tables.Add("temp",ds)
Document.Data.Tables.Remove(newDataTable)

#The following section will update the specified column in the database using the key column in the where clause
sqlStr=""
for  row in  Document.ActiveDataTableReference.GetRows(rowsToInclude,cursor1,cursor2):
   value1 = cursor1.CurrentValue
   value2 = cursor2.CurrentValue
   sqlStr = sqlStr +  "UPDATE Products SET " + colName + "='" + value2 + "' WHERE (ProductID=" + str(value1)  + ");"

sqlCommand = "UPDATE Products "  + sqlStr + ";"
dbsettings = DatabaseDataSourceSettings( "System.Data.SqlClient",
"Server=localhost;Database=Northwind;UID=myuser;PWD=mypass",sqlStr)
ds = DatabaseDataSource(dbsettings)
newDataTable = Document.Data.Tables.Add("temp",ds)
Document.Data.Tables.Remove(newDataTable)
