Overview

Implementation of select DRG CMS form field.

Form options:

  • name: field name (required)

  • type: select (required)

  • choices: Values for choices separated by comma. Values can also be specified like description:value.

In the example description will be shown to user, but value will be saved to document.

choices: 'OK:0,Ready:1,Error:2'
choices: Ruby,Pyton,PHP

  • eval: Choices will be provided by evaluating expression

    • eval: dc_choices4(‘model_name’,‘description_field_name’,‘_id’); dc_choices4 helper will provide data for select field.

    • eval: ModelName.choices4_field; ModelName class will define method choices4_field which

    will provide data for select field.

    • collection_name.search_field_name.method_name; When searching is more complex custom search

    method may be defined in CollectionName model which will provide result set for search.

  • If choices or eval is not defined choices will be provided from translation helpers. For example: Collection has field status choices for field may be provided by en.helpers.model_name.choices4_status entry of english translation. English is of course default translation. If you provide translations in your local language then select choices will be localized.

    en.helpers.model_name.choices4_status: 'OK:0,Ready:1,Error:2'
sl.helpers.model_name.choices4_status: 'V redu:0,Pripravljen:1,Napaka:2'

  • depend: Select options may depend on a value in some other field. If depend option is specified then chices must be provided by class method and defined in eval option.

  • html: html options which apply to select field (optional)

  • with_new: model_name.form_name will invoke view dialog for selected option

  • with_edit: model_name.form_name will invoke edit dialog for selected option

Form example:

30:
  name: type
  type: select
40:
  name: parent
  type: select
  eval: DcCategory.values_for_parent
  html:
    include_blank: true      
50:
  name: company
  type: select
  choices: Audi,BMW,Mercedes
    or
  choices: helpers.label.model.choices4_field
60:
  name: type
  type: select
  eval: Cars.choices4_type
  depend: company
