Add a Mashup or Mashable as an Information Source

Mashups in Presto Wires : Creating Mashups in Wires : Add a Mashup or Mashable as an Information Source

1. Find and select the mashup or mashable you want in the Block Menus.

See Quickly Find Mashables, Mashups or Other Blocks for search tips.

This opens a list of operations for this mashable or mashup in the Block Menu.

2. Select the operation you want to use and click

to add it to the design canvas or simply drag the operation to the position you want.

The block appears in the canvas with either the

Preview button or the

Inactive flag.

Note:

You can use inactive mashables or mashups in your mashup, but you cannot preview results for these blocks. You also cannot use the mashup until those services or mashups are activated.

3. Set any of the properties you need in the Block Properties pane.

Properties may be a simple list or they can be organized in a hierarchy. Properties may also have default values.

Properties may accept values directly or open the Path Selector list to allow you to supply the value from input fields or other blocks.

a. If needed, expand the hierarchy of properties.

b. Click in any property field and:

Enter a value.

If the Path Selector list opens, add an input field, select an existing input field or select a path to a field from another block to supply the value for the property dynamically. You can also click

to open the Path Selector list.

See Select Fields or Paths for Block Properties with the Path Selector for instructions.

Enter a Presto global or user attribute to supply the value for a property. See Use Presto Global or User Attributes in Block Properties for instructions.

c. Click

Run to preview the results.

It is a good practice to preview the results for this information source. Wires typically shows the results in the Tree view, to show both the structure and data of the result. You can also view just the data in the Grid view:

Note:

Some mashables and mashups return a large volume of results. Wires displays only the first 50 results. If you wish to see more results, your Presto administrator can change this setting. Be aware that large numbers of results can cause your browser to hang and stop responding.
