$processor$: get-data
get-data processor is used to get data from a JSON files in the package or from document-metadata in sitemap.
-- string foo: $processor$: get-data
Lang:
ftd
Assuming
foo: "hello" is part of “data”, the variable foo will be get “hello” as the value.Key
By default, the name of the variable or list where the data is being store is used as the key. You can overwrite the key using
key attribute:-- string foo: $processor$: get-data key: some-other-key-instead-of-foo
Lang:
ftd
Default Value
If the data is not found, we use the body as default value if body is available.
-- string foo: $processor$: get-data "hello world"
Lang:
ftd
The body must be valid json, compatible with the data type on which we are using the
get-data processor.Default Value in Caption For Basic Types
For basic types like
integer, boolean etc, the default value can also be provided in the caption. E.g.-- string foo: hello world $processor$: get-data
Lang:
ftd
Providing both
body and caption when using get-data is an error.Reading data from JSON File
We will be reading the data from JSON file and injecting the value to the caller of the processor (caller could be variable or component).
Step - 1 : We need to make two files i.e. one file should be .ftd and another file should be .json
Step - 2 : Creating .ftd (for example, record.ftd)-- record person: caption name: integer age: string gender: -- person arpita: $processor$: get-data file: foo.json -- ftd.text: $foo.name -- ftd.text: $foo.age -- ftd.text: $foo.gender
Lang:
ftd
Step - 3 : Creating .json (for example, foo.json)
{ "name": "arpita", "age": 15, "gender": "female" }
Lang:
ftd
Step - 4 : Output
arpita 15 female
Lang:
ftd
NOTE : It will throw an error if other than .json file is used.
