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

#criteriaJSS::Criteriable::Criteria Originally defined in module Criteriable

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

Returns:

#display_fieldsArray<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

# File 'lib/jss/api_object/advanced_search.rb', line 237

def display_fields
  @display_fields
end

#need_to_updateBoolean (readonly) Originally defined in module Updatable

Returns do we have unsaved changes?

Returns:

  • (Boolean)

    do we have unsaved changes?

#result_display_keysArray<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.

  @result_display_keys
end

#search_resultsArray<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

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

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

Parameters:

  • output_file (String, Pathname)

    The file in which to store the exported results

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

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_resultsArray<Hash>

Requery the API for the search results.

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