Fetching the comments written by a particular account.
Historically, applications that wanted to retrieve comments written by 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 comments by a particular author, we can use the
api = Radiator::Api.new api.get_account_history(account_name, -1, 10000) do |history| history.each do |index, item| type, op = item.op next unless type == 'comment' next if op.parent_author.empty? # skip posts next if op.parent_author == account_name # skip replies to account # . # ... your code here # . end end
Notice, the above example request up to 10,000 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 do not match the
Example api call
If we want to get the comments by 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_comments.rb lordvader
From the example we get the following output from our script:

Comments 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 firstname.lastname@example.org:steemit/devportal-tutorials-rb.git cd devportal-tutorials-rb/tutorials/09_get_account_comments bundle install ruby get_account_comments.rb <account-name>
