Extended by:
Retriable, Utils
Defined in:
lib/crea/broadcast.rb

Overview

These class methods make it simple to do things like broacast a Broadcast.vote or Broadcast.comment operation. They accept all of the fields expected by the blockchain plus the following additional options:

* wif
* url (optional)
* database_api (optional)
* block_api (optional)
* network_broadcast_api (optional)
* pretend (optional)

These options are not sent in the broadcast. The ‘wif` authorities can be posting, active, and owner.

Setting ‘url` will allow you to specify a different node instead of taking the default: (ChainConfig::NETWORKS_CREA_DEFAULT_NODE).

Setting ‘database_api`, `block_api`, and `network_broadcast_api` is optional, doing so will allow you to override the default node and/or the RPC Client.

When passing the ‘pretend` field, if it is set to True, nothing is broadcasted, but the `wif` is checked for the proper authority.

For details on what to pass to these methods, check out the Crea Developer Portal Broadcast Operations page.

.comment(options, &block) ⇒ Object

Creates a post/comment. This method simplifies content creation by combining ‘comment` and `comment_options` into one transaction.

options = {
  wif: wif,
  params: {
    author: author,
    title: 'This is my fancy post title.',
    body: 'This is my fancy post body.',
    metadata: {
      tags: %w(these are my fancy tags)

      {account: "frank", weight: 500}
    ]
  }
}

Crea::Broadcast.comment(options)

In addition to the above denormalized ‘comment_options` fields, the author can also vote for the content in the same transaction by setting `author_vote_weight`:

options = {
  wif: wif,
  params: {
    author: author,
    title: 'This is my fancy post title.',
    body: 'This is my fancy post body.',
    metadata: {
      tags: %w(these are my fancy tags)
    },
    author_vote_weight: 10000
