# Impulse Values

The liquid-field manipulator can use liquid templates to build a more complicated field value. There are two different attributes of the field that are used based on what type of field is being built.

1. Value
2. Relation

## Value

A value field is used for most field types.

Used with field types:

* Array
* Big Integer
* Big String
* Boolean
* Checkbox
* Date
* Date-Time
* Decimal
* Float
* Integer
* JSON
* Key Value
* Multi-select
* Radio
* Select
* String
* Text Area
* Time
* WYSIWYG

**Template**

```
[{"value":"<insert field value>"}]
[{"value":"<insert field value>"}, {"value":"<insert field value>"}]
```

**Example**

```
[{"value":"my static value"}]
[{"value":"my static value"}, {"value":"my second static value"}]
```

```
[{"value":"{{ content.fields.title.value }}"}]
[{"value":"{{ content.fields.first.value }}"}, {"value":"{{ content.fields.second.value }}"}]
```

## Relation

A relation field is used for any relationship type field.

Used with field types:

* Category
* File
* Image
* Relationship
* Tag

**Template**

```
[{"relations":{"parentIds":{"value":"{{content.id}}"}, "childIds":{"value":"<insert child ID value>"}}}]
[{"relations":{"parentIds":{"value":"{{content.id}}"}, "childIds":{"value":"<insert child ID value>"}}}, {"relations":{"parentIds":{"value":"{{content.id}}"}, "childIds":{"value":"<insert child ID value>"}}}]
```

**Example**

```
[{"relations":{"parentIds":{"value":"{{content.id}}"}, "childIds":{"value":"blt6eb2f3dd9c154fc7"}}}]
[{"relations":{"parentIds":{"value":"{{content.id}}"}, "childIds":{"value":"blt6eb2f3dd9c154fc7"}}}, {"relations":{"parentIds":{"value":"{{content.id}}"}, "childIds":{"value":"blt1716d8a3b330e674"}}}]
```

## Example Use Case

This use case creates a new array of relation values based on values found from an attribute in a JSON field. This uses a variety of filters and tags in the liquid template to convert an array of json strings to an array of relation values for a relationship field.

```
[

<div data-gb-custom-block data-tag="assign" data-rel_arr=''></div>

<div data-gb-custom-block data-tag="assign" data-0='.secondaryTerm[]' data-1='.secondaryTerm[]' data-2='.secondaryTerm[]'></div>

<div data-gb-custom-block data-tag="for">

 

<div data-gb-custom-block data-tag="unless" data-0='' data-1='' data-2=''>

  

<div data-gb-custom-block data-tag="assign" data-0='content.id' data-1='content.id' data-2='content.id' data-3=', ' data-4=', ' data-5=', ' data-6=', ' data-7=', ' data-8=', ' data-9=', ' data-10='category_secondary' data-child_id=''></div>

  

<div data-gb-custom-block data-tag="-"></div>

   {{ rel_arr | append: '{"relations":{"parentIds":{"value":"' | append: content.id | append: '"}, "childIds":{"value":"' | append: term | append: '"} } }' }}
  

<div data-gb-custom-block data-tag="-"></div>

   {{ rel_arr | append: '{"relations":{"parentIds":{"value":"' | append: content.id | append: '"}, "childIds":{"value":"' | append: term | append: '"} } }' | append: ',' }}
  

<div data-gb-custom-block data-tag="-"></div>

 

</div>

</div>
{{ rel_arr }}
]
```
