[英]Spotfire : How to modify an URL in an input field (after being entered by the user)
[英]Is there a way to get user input appended to a table in spotfire?
我在 Spotfire (dcube) 中有一个表Table1
,其中包含一些上下文信息,其中包含以下内容:
Name Food Seating
XYZ Seafood outdoors
我创建了一个带有两个按钮Yes
和No
的测试区域。 用户将在Table1
选择一条记录并单击其中一个按钮,它应该使用添加的列Preference
填充另一个表Table2
,输出如下:
Name Food Seating Preference
XYZ Seafood outdoor Yes
根据用户Yes
单击Yes
还是No
来填充preference
列的值。 当用户为Table1
另一条记录设置首选项时,它应该作为一行附加到Table2
。
在不使用 TERR 的情况下,这是否可以通过 R 或 IronPython 实现?
您可以使用 python 并写回数据库来实现这一点。 但是我不确定在没有外部数据源的情况下有什么好的/有效的方法来做到这一点。
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)
以上来自Tibco Spotfire我已将其用作模板,使用 SQL 服务器中的表在Spotfire中创建票证系统。
