Overview

Implementation of text_with_select DRG CMS form field. Field will provide text_field entry field with select dropdown box with optional values for the field. Form options are mostly same as in select field.

Form options:

  • name: field name (required)

  • type: text_with_select (required)

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

In this case 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. Since expression is evaluated in the context of Form Field object

Even session session variables can be accessed. 

eval: 'MyClass.method(@parent.session[:user_id])'

When searching is more complex custom search method may be defined in CollectionName model which will provide result set for search.

eval: collection_name.search_field_name.method_name;

If choices or eval is not defined choices will be provided from translation helpers. For example: Collection has field status. Choices for field will 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'

  • html: html options which apply to select and text_field fields (optional)

Form example:

10:
  name: link
  type: text_with_select
  eval: '@parent.dc_page_class.all_pages_for_site(@parent.dc_get_site)'
  html:
    size: 50
