Overview

Implementation of radio_button AgileRails form field. Field provides radio_button input field. structure. Form options are mostly same as in select field.

Form options:

  • name: field name (required)

  • type: radio_button (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: agile_choices_for(‘model_name’,‘description_field_name’,‘_id’); agile_choices_for helper will provide data for select field. eval: ModelName.choices_for_field; ModelName class will define method choices_for_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(@env.session[:user_id])'

When searching is more complex custom search method may be defined in CollectionName model which will provide dataset 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.choices_for_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.choices_for_status: 'OK:0,Ready:1,Error:2'
sl.helpers.model_name.choices_for_status: 'V redu:0,Pripravljen:1,Napaka:2'

  • inline: radio buttons will be presented inline instead of stacked on each other.

Form example:

10:
  name: hifi
  type: radio_button
  choices: 'Marantz:1,Sony:2,Bose:3,Pioneer:4'
  inline: true
