YAML data import module for Zotonic

This module lets you import data in YAML format to create new Zotonic Pages.

Pages are represented as YAML list items. Item properties are translated to Page attributes (title, summary, is_published, ...).

Medium URLs can be attached automatically; pages can be connected using predicates.

Next to pages, categories and predicates can be created as well.


Before trying out, first backup you data!


Example data file

%YAML 1.1
---
-
  title: "Cheesy Vegemite pull-apart"
  summary: "Put these cheesy vegemite scrolls into the school lunch-box as an exciting alternative to the sandwich."
  img: "http://www.taste.com.au/images/recipes/sfi/2009/03/22132_l.jpg"
  recipe_tag: "Kids in the kitchen"
-
  title: "Chicken nuggets"
  summary: "Why not let the kids create their own healthy version of chicken nuggets."
  img: "http://www.taste.com.au/images/recipes/tas/2012/01/27997_l.jpg"
  recipe_tag: "Kids in the kitchen"
...

In this example file:

  • title and summary naturally map to Zotonic Page attributes.
  • img can be mapped to medium (to import the image file)
  • recipe_tag can be mapped to Keyword (if the Predicate connection allows this, and the Keyword with that title exists)

Features

The import wizard offers the option to finetune the data before importing, to:

  • rename fields
  • select fields to exclude
  • map the title field if it does not exist in the data
  • map the fields to media type, to automatically download and import media files
  • map the fields to other data types (using a predicate)
  • import a range

To be imported data can be previewed.

Before importing, you can choose Test Run (output is still rather basic).

One category per file

The data file cannot have more than one data structure: all records should be structured the same. Split up the YAML file if you need to import pages in multiple categories.

Importing multiple images

For the property to be mapped to medium, pass a comma-delimited string:

%YAML 1.1
---
# Recipes
-
  title: "Cheesy Vegemite pull-apart"
  summary: "Put these cheesy vegemite scrolls into the school lunch-box as an exciting alternative to the sandwich."
  img: http://www.taste.com.au/images/recipes/sfi/2009/03/22132_l.jpg, http://www.taste.com.au/images/recipes/sfi/2010/03/24404_l.jpg
...
  • At Data Type, choose Medium
  • Check "Multiple import from comma-separated list"

Importing categories

A YAML file to create new categories should have at least the attributes title and name. Example:

%YAML 1.1
---
-
  title: "Recipe"
  name: "recipe"
  is_published: "true"
-
  title: "Recipe category"
  name: "recipe_category"
  is_published: "false"
...
  1. Upload the data source.
  2. At "Create Page type", choose "Category". For attribute is_published, change Data Type from text (in the dialog, choose Status, then "is_published").

Importing predicates

A YAML file to create new predicates should have 4 mandatory attributes for each predicate:

  • title
  • name: must be unique
  • from: similar to Predicate edit screen - the category name (not title)
  • to: similar to Predicate edit screen - the category name (not title)

All attributes have type Text.

Example:

%YAML 1.1
---
-
  title: "Has primary category"
  name: "has_primary_category"
  from: "navigation"
  to: "primary_category"
...

Troubleshooting

  • In case international characters are garbled: make sure the text is saved as UTF-8 (no BOM).

  • In case the module does not import the file at all: make sure the list ends with a newline, and then 3 dots:

      ...
    

Installation

See file INSTALL.

TODO

  • Better error reporting (also in Test Run mode).
  • Support for translation strings.
