Edit a post's attachments and poll

:::tip Rewards
Upon completing this challenge, you will be rewarded 50 Desmos Tokens.

Please note that in order to prevent spam, you will receive the reward just for the first post you edit. No tokens will be awarded for later posts. :::

With version v0.12.0 we've implemented the ability for users to edit posts' attachments and polls.

Editing your first post with some attachments and a poll

Creating the post

Before editing a post and its attachments and poll data, we need to create one. You can do so by running the following command:

The command will then look like this:

desmoscli tx posts create "<Subspace>" \
  --poll-details "question=<Question>,mutiple-answers=<true/false>,allows-answer-edits=<true/false>,end-date=<Poll ending date>" \
  --poll-answer <First answer> \
  --poll-answer <Second answer> \
  ...
  --attachment "<URL>,<Mime type>" \
  --attachment "<URL>,<Mime type>" \
  ...
  --from <your-key-name> --yes \
  --chain-id <chain-id>

Here's an example of such command:

desmoscli tx posts create 4e188d9c17150037d5199bbdb91ae1eb2a78a15aca04cb35530cccb81494b36e \
  --poll-details "question=Which dog do you prefer?,multiple-answers=false,allows-answer-edits=true,end-date=2021-01-01T15:00:00.000Z" \
  --poll-answer "Beagle" \
  --poll-answer "Pug" \
  --poll-answer "German Sheperd" \
  --attachment "https://www.w3schools.com/w3css/img_lights.jpg,image/jpeg" \
  --from jack --yes \
  --chain-id morpheus-10000

Once you've run that command you will be asked to type the password you've chosen during the setup and after having inserted it properly you should see something like this:

height: 0
txhash: E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290
codespace: ""
code: 0
data: ""
rawlog: '[]'
logs: []
info: ""
gaswanted: 0
gasused: 0
tx: null
timestamp: ""

To make sure the transaction has been processed successfully, you can query it using the following command:

desmoscli query tx <hash> --trust-node --output json

# Example
# desmoscli query tx E4920B61BFCFB935124FFC22BC04C1D5619943B138C87913E6EBCF2B5E892290 \
  --trust-node --output json

This will return you the JSON representation of the transaction itself.

Editing the post

Now that the post has been created, we can edit it.

To do so, we can use the following command:

desmoscli tx posts edit "<Post ID>" \
  --poll-details "question=<Question>,mutiple-answers=<true/false>,allows-answer-edits=<true/false>,end-date=<Poll ending date>" \
  --poll-answer <First answer> \
  --poll-answer <Second answer> \
  ...
  --attachment "<URL>,<Mime type>" \
  --attachment "<URL>,<Mime type>" \
  ...
  --from <your-key-name> --yes \
  --chain-id <chain-id>

Here's an example of such command:

desmoscli tx posts edit 19de02e105c68a60e45c289bff19fde745bca9c63c38f2095b59e8e8090ae1af \
  --poll-details "question=Which dog do you prefer?,multiple-answers=false,allows-answer-edits=true,end-date=2021-01-01T15:00:00.000Z" \
  --poll-answer "Beagle" \
  --poll-answer "Pug" \
  --poll-answer "Poodle" \
  --attachment "https://www.w3schools.com/w3css/img_forest.jpg,image/jpeg" \
  --from jack --yes \
  --chain-id morpheus-10000

:::tip Getting your post ID
In order to get the id of the post you previously created, you have two options:

1. Using the CLI and the following command:

   desmoscli q posts posts \
     --creator=$(desmoscli keys show <your-key-name> --address)

2. Using our REST APIs.
