Fetching the replies written to a particular account.
Historically, applications that wanted to retrieve replies written to a particular account would use
get_state. But this method has been scheduled for deprecation. So we’ll use a more supported approach in this tutorial using
- Making the api call - Requesting account history
- Comment Fields - Getting more detail than provided by account history.
- To Run - Running the example.
Making the api call
To request the latest replies to a particular author, we can use the
api = Radiator::Api.new options =  options << account_name options << -1 # start options << 1000 # limit # This is optional, we can mask out all operations other than comment_operation. operation_mask = 0x02 # comment_operation options << (operation_mask & 0xFFFFFFFF) # operation_filter_low options << ((operation_mask & 0xFFFFFFFF00000000) >> 32) # operation_filter_high api.get_account_history(*options) do |history| history.each do |index, item| type, op = item.op next unless type == 'comment' next if op.parent_author.empty? # skip posts next unless op.parent_author == account_name # skip comments by account # . # ... your code here # . end end
Notice, the above example request up to 1,000 operations from history, starting from the oldest. From these results, we iterate on each item in history to locate a) type of
comment, and b)
parent_author that match the
This example also shows how to mask out all but
comment_operation. This is optional, but by providing this mask, the api response will only include posts and replies, reducing the bandwidth required to execute this api call.
Example api call
If we want to get the replies to user @lordvader …
api.get_account_history("lordvader") do |content| ...
Example api call using script
And to do the same with our tutorial script
ruby get_account_replies.rb lordvader
From the example we get the following output from our script:

Replies in the results of
get_account_history will only return the following fields:
In our example script, we want more detail than this, so for every
comment, we call
get_content to retrieve more detail. For a full explanation of the results provided by
get_content, please refer to the tutorial: Get Post Details
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/08_get_account_replies bundle install ruby get_account_replies.rb <account-name>
