Inherits:
APIObject show all
Includes:
Creatable, Criteriable, Updatable
Defined in:
lib/jss.rb,
lib/jss/api_object/advanced_search.rb

Overview

A Parent class for Advanced Computer, MobileDevice, and User searchs

Subclasses must define:

  • the constant RESULT_CLASS which is the JSS Module class of the item returned by the search, e.g. JSS::Computer

  • the constant RESULT_ID_FIELDS, which is an Array of Symbols that come from the API in the search_results along with the symbolized display fields. E.g. for AdvancedComputerSearches, :id, :name, and :udid are present along with whatever display fields have been defined.

Instance Attribute Details

#criteria ⇒ JSS::Criteriable::Criteria Originally defined in module Criteriable

Returns the criteria for the instance into which we’re mixed.

Returns:

#need_to_update ⇒ Boolean (readonly) Originally defined in module Updatable

Returns do we have unsaved changes?.

Returns:

  • (Boolean) —

    do we have unsaved changes?

#result_display_keys ⇒ Array<Symbol> (readonly)

The search result Hash keys for the #display_fields of the search

The field names in #display_fields are strings matching how the field is labeled in the web UI (including the names of Extension Attributes). They have to be that way when submitting them to the API, and thats mostly what #display_fields and related methods are for.

However, when those names come back as the Hash Keys of the #search_results they (inconsistently) have spaces and/or dashes converted to underscores, and, the JSON module converts the keys to Symbols, so they don’t match the #display_fields.

For example, the display field “Last Check-in” might come back as any of these Symbols:

  • :“Last Check-in”

  • :Last_Check_in

  • :“Last_Check-in”

Also, the data returned in the #search_results contains more keys than just the #display_fields - namely it comes with some standard identifiers for each found item. such as JSS id number and name.

#result_display_keys will hold just the Hash keys corresponding to the #display_fields by taking the keys from the first result Hash, and removing the identifier keys as listed in each subclass’s RESULT_ID_FIELDS constant.

Returns:

def result_display_keys
  @result_display_keys
end

#search_results ⇒ Array<Hash> (readonly)

Each Hash is one object that matches the criteria. Within each hash there are variable keys, but always at least the keys defined in each subclasses RESULT_ID_FIELDS

The other keys correspond to the #display_fields defined for this Advanced Search.

Returns:

  • (Array<Hash>) —

    the results of the search

Instance Method Details

#clone(new_name) ⇒ APIObject Originally defined in module Creatable

make a clone of this API object, with a new name. The class must be creatable

Parameters:

  • name (String) —

    the name for the new object

Returns:

  • (APIObject) —

    An uncreated clone of this APIObject with the given name

Raises:

#count ⇒ Integer

Returns the number of items found by the search.

Returns:

  • (Integer) —

    the number of items found by the search

def count

end

#create(get_results = false) ⇒ Integer

Create in the JSS

If get_results is true, they’ll be available in #search_results. This might be slow.

Parameters:

  • get_results (Boolean) (defaults to: false) —

    should the results of the search be queried immediately?

Returns:

  • (Integer) —

    the id of the newly created search

  @id # remember to return the id

end

#display_fields ⇒ Array<String>

The API delivers these as an array of Hashes, where each hash has only one key, :name => the name of the fields/ExtAttrib to display. It should probably not have the underlying Hashes, and just be an array of names. This class converts it to just an Array of field names (Strings) for internal use.

These fields are returned in the @search_results data along with :id, :name, and other unique identifiers for each found item. In that data, their names have spaces and dashes converted to underscores, and they are symbolized.

Returns:

  • (Array<String>) —

    the fields to be returned with the search results

#export(output_file, format = :csv, overwrite = false) ⇒ Pathname

Note:

This method only exports the display fields defined in this advanced search for

Export the display fields of the search results to a file.

the search_result members (computers, mobile_devices, or users) It doesn’t currently provide the ability to export subsets of info about those objects, as the Web UI does (e.g. group memberships, applications, receipts, etc)

Parameters:

  • output_file (String, Pathname) —

    The file in which to store the exported results

  • format (Symbol) (defaults to: :csv) —

    one of :csv, :tab, or :xml, defaults to :csv

  • overwrite (Boolean) (defaults to: false) —

    should the output_file be overwrite if it exists? Defaults to false

Returns:

  • (Pathname) —

    the path to the output file

#name=(newname) ⇒ void Originally defined in module Updatable

This method returns an undefined value.

Change the name of this item Remember to #update to push changes to the server.

Parameters:

  • newname (String) —

    the new name

Raises:

#parse_criteria ⇒ void Originally defined in module Criteriable

This method returns an undefined value.

During initialization, convert the @init_data Hash into a JSS::Criteriable::Criteria instance stored in @criteria

Classes mixing in this module must call this in #initialize

#requery_search_results ⇒ Array<Hash>

Requery the API for the search results.

This can be very slow, so temporarily reset the API timeout to 30 minutes

#should_update ⇒ void Originally defined in module Criteriable

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

This method returns an undefined value.

Allow our Criteria to tell us when there’s been a change that needs to be updated.

#update(get_results = false) ⇒ Integer

Save any changes

If get_results is true, they’ll be available in #search_results. This might be slow.

Parameters:

  • get_results (Boolean) (defaults to: false) —

    should the results of the search be queried immediately?

Returns:

  • (Integer) —

    the id of the updated search
