Defined in:

lib/decidim/term_customizer/import/readers/base.rb

Overview

Imports an exported file to data arrays that can be processed during yields.

Direct Known Subclasses

CSV, JSON, XLS

Instance Method Summary

• #initialize(file) ⇒ Base constructor

  A new instance of Base.

• #read_rows ⇒ Object

  The read_rows method should iterate over each row of the data and yield the data array of each row with the row’s index.

Constructor Details

#initialize(file) ⇒ Base

Returns a new instance of Base.

def initialize(file)
  @file = file
end

Instance Method Details

#read_rows ⇒ Object

The read_rows method should iterate over each row of the data and yield the data array of each row with the row’s index. For example, this could look like following:

Parser.read(file).rows.each_with_index do |row, index|
  yield row.to_a, index
end

The first row yielded with index 0 needs to contain the data headers which can be later used to map the data to correct attributes.

This needs to be implemented by the extending classes.

Raises:

• (NotImplementedError)

# File 'lib/decidim/term_customizer/import/readers/base.rb', line 25

def read_rows
  raise NotImplementedError
