Hive Developer Portal
List of replies received by account to its content, post, comment.
Full, runnable src of Get Account Replies can be downloaded as part of: tutorials/python (or download just this tutorial: devportal-master-tutorials-python-08_get_account_replies.zip).
Tutorial will explain and show you how to access the Hive blockchain using the beem library to fetch a list of comments made on a specific accounts content.
In Hive there are built-in functions in the library
beem that we are going to use throughout all Python tutorials. For this one we are using the
- App setup - Library install and import
- Post list - List of filters to select from
- Comment details - Form a query
- Print output - Print results in output
In this tutorial we use 3 packages,
pick - helps us to select filter interactively.
beem - hive library, interaction with Blockchain.
pprint - print results in better format.
First we import all three library and initialize Hive class
import pprint from pick import pick # initialize Hive class from beem import Hive from beem.discussions import Query, Discussions from beem.account import Account h = Hive()
Next we will fetch and make a list of posts and setup
q = Query(limit=2, tag="") d = Discussions() #post list for selected query #we are merely using this to display the most recent posters #the 'author' can easily be changed to any value within the 'reply_history' function posts = d.get_discussions('created', q, limit=2) title = 'Please choose author: ' options =  #posts list for post in posts: options.append(post["author"]) # get index and selected filter name option, index = pick(options, title) # option is printed as reference pprint.pprint("Selected: " + option)
This will show us list of posts to select in terminal/command prompt. And after selection we will get index and post name to
option variables. We will also print the selection on screen for easy reference.
Next we will allocate variables to make the function easier to use as well as provide a limit for the number of replies that we want to print. To retreive the replies we only need the
author object. This is then used in the
reply_history function present in the beem library.
# in this tutorial we are showing usage of reply_history of post where the author is known # allocate variables _author = Account(option) _limit = 1 # get replies for specific author replies = _author.reply_history(limit=_limit)
Next, we will print the details obtained from the function by iterating the array.
# print specified number of comments for reply in replies: pprint.pprint(reply.body)
