Script
This script will pick a method to call based on the arguments passed. The expected categories are:
- trending
- hot
- active
- created
- votes
- promoted
- children
We will base the name of the API method to execute on the provided argument. Once we know which method to execute, we can build the query options. The defaults for this script is limit: 10
and tag: ''
.
For each post we retrieve, we are going to build up a summary to display the interesting fields. In this case, we’re interested in:
- Creation Timestamp
- Title
- Author
- Net Votes
- Number of replies
- If it’s promoted
- Number of words in the body
- Canonical URL
To Run
First, set up your workstation using the steps provided in Getting Started. Then you can create and execute the script (or clone from this repository):
git clone https://gitlab.syncad.com/hive/devportal.git
cd devportal/tutorials/ruby/04_get_posts
bundle install

Error Handling
We’re checking the result for error
in case the remote node has an issue to raise. Normally, it will be nil
, but if it’s populated, output error.message
and exit.
