Overview

Schema information

Collection name: dc_memory : Collection name used when form does not belong to database model.

Which is not collection at all. DcMemory model is used for entering data on forms where data will not be saved to database but will instead be saved only to memory as temporary variable and processed by custom made methods. For example, define start and end date when making a timeline report.

Example (as used in forms):

table: dc_memory
title: Enter time period

  form:
    actions:
      1:
        type: ajax
        method: post
        controller: reports
        action: do_some_report
        caption: Run report

    fields:
      10:
        name: date_start
        type: date_picker
        caption: Start date
      20:
        name: date_end
        type: date_picker
        caption: End date

And suppose your report saved data to file named public/report.pdf. Put this line at the end of do_some_report method:

render inline: { :window_report => '/report.pdf' }.to_json, formats: 'js'

As result report.pdf file will be opened in new browser window.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(m, *args, &block) ⇒ Object

Method missing will return value if value defined by m parameter is saved to
