URL actions in Tableau - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a URL action that opens a website when a user clicks a mark.

Tableau

URL Action: 'https://www.example.com/' || [1]

Drag options to blanks, or click blank then click option'

A[Category]

BSUM([Sales])

C[ProductID]

D[Region]

Attempts:

3 left

💡 Hint

Common Mistakes

Using aggregated fields like SUM([Sales]) in the URL action.

Using a category or region which may not uniquely identify the item.

The URL action should use a field that uniquely identifies the item, such as ProductID, to direct the user to the correct page.

2fill in blank

medium

Complete the code to encode the URL parameter correctly for spaces.

Tableau

URL Action: 'https://www.example.com/search?query=' || [1]

Drag options to blanks, or click blank then click option'

AREPLACE([Product Name], ' ', '%20')

BLOWER([Product Name])

CUPPER([Product Name])

DLEFT([Product Name], 5)

Attempts:

3 left

💡 Hint

Common Mistakes

Using LOWER or UPPER functions which do not encode spaces.

Using LEFT which truncates the string but does not encode spaces.

Spaces in URLs must be encoded as %20. The REPLACE function substitutes spaces with %20.

3fill in blank

hard

Fix the error in the URL action expression to concatenate base URL and parameter correctly.

Tableau

URL Action: 'https://www.example.com/product=' [1] [ProductID]

Drag options to blanks, or click blank then click option'

A&

B+

C+='

D||

Attempts:

💡 Hint

Common Mistakes

Using + which is not valid for string concatenation in Tableau.

Using & which is used in some other languages but not Tableau.

In Tableau, string concatenation uses the || operator, not + or &.

4fill in blank

hard

Fill both blanks to create a URL action that opens a Google search for the selected category.

Tableau

URL Action: 'https://www.google.com/search?q=' || [1] || REPLACE([2], ' ', '+')

Drag options to blanks, or click blank then click option'

A[Category]

B[Product Name]

C[Region]

D[Customer]

Attempts:

3 left

💡 Hint

Common Mistakes

Using different fields in the two blanks.

Using fields that are not relevant for the search.

The URL action should use the Category field and replace spaces with '+' for Google search queries.

5fill in blank

hard

Fill all three blanks to build a URL action that opens a map with the selected city and state.

Tableau

URL Action: 'https://maps.example.com/?city=' || [1] || ' &state=' || [2] || REPLACE([3], ' ', '%20')

Drag options to blanks, or click blank then click option'

A[City]

B[State]

D[Country]

Attempts:

3 left

💡 Hint

Common Mistakes

Using Country instead of State.

Not encoding the city name for spaces.

The URL uses City for the city parameter (also encoded for spaces), and State for the state parameter.

Practice

1. What is the primary purpose of URL actions in Tableau dashboards?

easy

A. To export dashboard data to Excel files

B. To link dashboard elements to external web pages or resources

C. To filter data within the dashboard automatically

D. To change the color of dashboard charts dynamically

Solution

1. Step 1: Understand URL actions functionality

   URL actions allow dashboard elements to open web pages or external resources when triggered.

2. Step 2: Compare other options

   Changing colors or filtering data are done by other Tableau features, not URL actions.

3. Final Answer:

   To link dashboard elements to external web pages or resources -> Option B

4. Quick Check:

   URL actions = link to web pages [OK]

Hint: URL actions connect dashboards to websites or files [OK]

Common Mistakes:

• Confusing URL actions with filters
• Thinking URL actions change dashboard visuals
• Assuming URL actions export data

2. Which of the following is the correct syntax to insert a field value into a URL action in Tableau?

easy

A. http://example.com/product=[Product ID]

B. http://example.com/product=<[Product ID]>

C. http://example.com/product=<Product ID>

D. http://example.com/product=Product ID

Solution

1. Step 1: Identify Tableau field insertion syntax

   Tableau uses angle brackets around the exact field name without brackets inside, like <Product ID>.

2. Step 2: Check options for correct syntax

   http://example.com/product=<Product ID> correctly uses <Product ID> without extra brackets or symbols.

3. Final Answer:

   http://example.com/product=<Product ID> -> Option C

4. Quick Check:

   Field insertion = <Field Name> [OK]

Hint: Use <Field Name> exactly to insert field values in URLs [OK]

Common Mistakes:

• Adding extra brackets inside angle brackets
• Using square brackets inside URL
• Forgetting angle brackets around field name

3. Given a URL action set as http://sales.com/details?region=<Region>&product=<Product>, what URL will open when a user clicks on a data point with Region = 'West' and Product = 'Shoes'?

medium

A. http://sales.com/details?region=<Region>&product=<Product>

B. http://sales.com/details?region=West&product=

C. http://sales.com/details?region=Shoes&product=West

D. http://sales.com/details?region=West&product=Shoes

Solution

1. Step 1: Substitute field values into URL

   Replace <Region> with 'West' and <Product> with 'Shoes' in the URL template.

2. Step 2: Verify correct order and values

   The URL becomes http://sales.com/details?region=West&product=Shoes exactly as in http://sales.com/details?region=West&product=Shoes.

3. Final Answer:

   http://sales.com/details?region=West&product=Shoes -> Option D

4. Quick Check:

   Field values replace placeholders correctly [OK]

Hint: Replace placeholders with actual field values in URL [OK]

Common Mistakes:

• Mixing up field values order
• Not replacing placeholders
• Leaving placeholders unchanged

4. You created a URL action but clicking it does nothing. Which of the following is the most likely cause?

medium

A. The URL contains incorrect field syntax like missing angle brackets

B. The dashboard filter is not applied

C. The data source is not refreshed

D. The worksheet has no filters

Solution

1. Step 1: Check URL action syntax

   If the URL syntax is wrong, such as missing < and > around fields, Tableau cannot build the URL properly.

2. Step 2: Understand other options

   Filters or data refresh issues do not prevent URL actions from triggering clicks.

3. Final Answer:

   The URL contains incorrect field syntax like missing angle brackets -> Option A

4. Quick Check:

   Incorrect syntax blocks URL action [OK]

Hint: Check angle brackets around fields in URL [OK]

Common Mistakes:

• Ignoring syntax errors in URL
• Blaming filters for URL action failure
• Not testing URL outside Tableau

5. You want to create a URL action that opens a Google search for the selected product name. Which URL template should you use to make the search dynamic?

hard

A. https://www.google.com/search?q=<Product Name>

B. https://www.google.com/search?q=Product Name

C. https://www.google.com/search?q=[Product Name]

D. https://www.google.com/search?q={Product Name}

Solution

1. Step 1: Identify correct field insertion syntax

   Tableau requires angle brackets around the exact field name to insert dynamic values, so <Product Name> is correct.

2. Step 2: Check URL format for Google search

   The URL https://www.google.com/search?q= followed by the field value creates a dynamic search link.

3. Final Answer:

   https://www.google.com/search?q=<Product Name> -> Option A

4. Quick Check:

   Dynamic URL uses <Field Name> syntax [OK]

Hint: Use <Field Name> to insert dynamic values in URLs [OK]

Common Mistakes:

• Using brackets other than angle brackets
• Hardcoding field names as text
• Forgetting to include query parameter 'q='
