/**
|
|
* @module SearchSelect
|
|
* The `SearchSelect` is an implementation of the [ember-power-select](https://github.com/cibernox/ember-power-select) used for form elements where options come dynamically from the API.
|
|
* @example
|
|
* <SearchSelect
|
|
* @id="policy"
|
|
* @models={{array "policies/acl"}}
|
|
* @onChange={{this.onChange}}
|
|
* @inputValue={{get @model this.valuePath}}
|
|
* @wildcardLabel="role"
|
|
* @fallbackComponent="string-list"
|
|
* @selectLimit={{1}}
|
|
* @backend={{@model.backend}}
|
|
* @disallowNewItems={{true}}
|
|
* class={{if this.validationError "dropdown-has-error-border"}}
|
|
* />
|
|
*
|
|
// * component functionality
|
|
* @param {function} onChange - The onchange action for this form field. ** SEE UTIL ** search-select-has-many.js if selecting models from a hasMany relationship
|
|
* @param {array} [inputValue] - Array of strings corresponding to the input's initial value, e.g. an array of model ids that on edit will appear as selected items below the input
|
|
* @param {boolean} [disallowNewItems=false] - Controls whether or not the user can add a new item if none found
|
|
* @param {boolean} [shouldRenderName=false] - By default an item's id renders in the dropdown, `true` displays the name with its id in smaller text beside it *NOTE: the boolean flips automatically with 'identity' models or if this.idKey !== 'id'
|
|
* @param {array} [parentManageSelected] - Array of selected items if the parent is keeping track of selections, see mfa-login-enforcement-form.js
|
|
* @param {boolean} [passObject=false] - When true, the onChange callback returns an array of objects with id (string) and isNew (boolean) (and any params from objectKeys). By default - onChange returns an array of id strings.
|
|
* @param {array} [objectKeys] - Array of values that correlate to model attrs. Used to render attr other than 'id' beside the name if shouldRenderName=true. If passObject=true, objectKeys are added to the passed, selected object.
|
|
* @param {number} [selectLimit] - Sets select limit
|
|
|
|
// * query params for dropdown items
|
|
* @param {Array} models - An array of model types to fetch from the API.
|
|
* @param {string} [backend] - name of the backend if the query for options needs additional information (eg. secret backend)
|
|
* @param {object} [queryObject] - object passed as query options to this.store.query(). NOTE: will override @backend
|
|
|
|
// * template only/display args
|
|
* @param {string} id - The name of the form field
|
|
* @param {string} [label] - Label for this form field
|
|
* @param {string} [labelClass] - overwrite default label size (14px) from class="is-label"
|
|
* @param {string} [subText] - Text to be displayed below the label
|
|
* @param {string} fallbackComponent - name of component to be rendered if the API call 403s
|
|
* @param {string} [helpText] - Text to be displayed in the info tooltip for this form field
|
|
* @param {string} [wildcardLabel] - string (singular) for rendering label tag beside a wildcard selection (i.e. 'role*'), for the number of items it includes, e.g. @wildcardLabel="role" -> "includes 4 roles"
|
|
* @param {string} [placeholder] - text you wish to replace the default "search" with
|
|
* @param {boolean} [displayInherit=false] - if you need the search select component to display inherit instead of box.
|
|
* @param {function} [renderInfoTooltip] - receives each inputValue string and list of dropdownOptions as args, so parent can determine when to render a tooltip beside a selectedOption and the tooltip text. see 'oidc/provider-form.js'
|
|
*
|
|
// * advanced customization
|
|
* @param {Array} options - array of objects passed directly to the power-select component. If doing this, `models` should not also be passed as that will overwrite the
|
|
* passed options. ex: [{ name: 'namespace45', id: 'displayedName' }]. It's recommended the parent should manage the array of selected items if manually passing in options.
|
|
* @param {function} search - Customizes how the power-select component searches for matches - see the power-select docs for more information.
|
|
*
