Create, get, remove datatable relations in Spotfire using Python

Create, get, remove datatable relations in Spotfire using Python

Imagine you have a data table with countries:

Country code Country name
HKG Hong Kong
ISR Israel
MYS Malaysia

And data table with languages related to these countries:

Country code Language Percentage
HKG Canton Chinese 88.7
HKG Chiu chau 1.4
HKG English 2.2
HKG Fukien 1.9
HKG Hakka 1.6
ISR Arabic 18.0
ISR Hebrew 63.1
ISR Russian 8.9
MYS Chinese 9.0
MYS Dusun 1.1
MYS English 1.6
MYS Iban 2.8
MYS Malay 58.4
MYS Tamil 3.9

Where "Country code" is the common field.

You would like to create link between these tables. It is possible to create relation manually in Spotfire, but for some reason you need to create it automatically via Python script.

Create relation between tables

def add_relation(table1, table2, link_expression):
    Document.Data.Relations.Add(
        Document.Data.Tables[table1],
        Document.Data.Tables[table2],
        link_expression)

Usage:

add_relation("country", "lang", "[lang].[Country code]=[country].[Country code]")

Now you are able to select country in the "country" table and all related languages from the "lang" table will also be selected.

Like here:

Spotfire linked tables

Get relation expression

def get_relation(table1, table2):
    return Document.Data.Relations.FindRelation(
        Document.Data.Tables[table1],
        Document.Data.Tables[table2])

Usage:

print(get_relation("country", "lang").Expression)
# [lang].[Country code]=[country].[Country code]

Delete relation

def del_relation(table1, table2):
    relation = Document.Data.Relations.FindRelation(
        Document.Data.Tables[table1],
        Document.Data.Tables[table2])
    if relation:
        Document.Data.Relations.Remove(relation)

Usage:

del_relation("country", "lang")

Check that Spotfire document has a Visualization on a Page using Python

Just use this simple Python function:

def has_visualization(page_name, vis_name):
    for page in Document.Pages:
        if page.Title == page_name:
            for vis in page.Visuals:
                if vis.Title == vis_name:
                    return True

Try it:

print(has_visualization("SomePage", "SomeChart")) # True
print(has_visualization("SomePage", "ChartNotExists")) # None

Show URLs in Spotfire Table

Show URLs in Spotfire Table

Spotfire uses auto-detection to set URL renderer for a table column. So, if all values in a column start with "http://" or "https://" it sets URL renderer.

Like here:

Spotfire table with URLs

Moreover, it is possible to set URL renderer for columns in which the values do not look like URLs. But these values can be used as parameters for URLs.

Like here in the "Param Links" column:

Spotfire table parameterized URLs

The only step you need is to specify URL with a placeholder:

Spotfire URL renderer settings

via "Table Properties->Columns"

Spotfire column properties

Don't forget to choose "Link" as a "Renderer".
