I'm either missing something really fundamental here or there are some missing instructions for turning the pallet template into an empty kitties pallet.

1. Basic set-up
   • under Getting started with the node template
     • Might be worth adding "all instances of node-template and node-template-runtime in /node/Cargo.toml under features, bin, package, and dependencies should be renamed"; instructions are vague and might suggest not renaming under deps or benchmarks.
   • under Creating and integrating pallet_kitties
     • Should we copy the "most bare-bones version" pallet code into pallets/kitties/src/lib.rs? If so, we should state that. So far, it only describes what a bare-bones pallet looks like but then doesn't use it to explain anything.
     • instructing to rename pallets/template to pallet/kitties breaks everything related to pallet_template in runtime/src/lib.rs:
       • this includes the import, config impl, TemplateModule reference, benchmarks at the bottom, so instructions handling that should be included
     • include instructions to rename pallets/template to pallets/kitties in /Cargo.toml.
     • Fix all references to pallet_template in runtime/src/lib.rs. There are several, and they don't exist anymore
     • it says the the pallets/kitties/Cargo.toml file should be modified, but it does not say what needs to be modified
       • include instructions of "rename pallet-template to pallet-kitties"
       • in runtime/Cargo.toml include instructions to rename every instance of
         • pallet-template to pallet-kitties
         • ../pallets/template to ../pallets/kitties
       • in runtime/src/lib.rs rename pallet_template to pallet_kitties
     • impl pallet_kitties::Config for Runtime {} implements an empty config for runtime, but it is never included in construct_runtime!

Hi there,

Trying to set up this pallet, but I get the following errors.

Is something missing from the storage declaration below?

/// Storage item for balances to accounts mapping. #[pallet::storage] #[pallet::getter(fn get_balance)] pub(super) type BalanceToAccount<T: Config> = StorageMap< _, Blake2_128Concat, T::AccountId, T::Balance, ValueQuery >;

 cargo +nightly build --release

results in:

Also, coming from many other different languages I find it surprising the +nightly pervasive usage. Removing it makes compilation work in my particular environment.

Who is in charge of some projects? Can you support it? I follow the tutorial and can't understand it at all. The subject node template I saw has been updated to monthly-2021-07 release by Jimmy Chu. I can't compile in step 3 of part I: basic setup

As I copy over the bare-bones of the pallet into kitties/src/lib.rs, it can't be build or check directly, the compiler said SubstrateKitties does not have defined, and the full error is as followed:

I look for some more or less working example of staking pallet and found the example and I have found not updated documentation.

Here is the source of new functions.

Trying to use the latest stable node, npm

nvm use stable
Now using node v14.13.0 (npm v7.24.0)

Updating packages, removing unused ones, start at modifying to get the build working. I am stuck here, and would love some support to get this working and merge-able :pray:

Having a script that sets a template node up in a single command would speed things up for new comers. This would alleviate potential issues as raised in #36.

It would take away a large chunk of what's in Kitties Part I for example, resulting in a more rewarding experience.

1. Right now the "tags" are in the form of keywords in the metadata of each guide. Working on a solution to have them displayed as a component under each heading. Possibly an MDX thing.
2. In tandem, modify search functionality to display content by tags.

Hi, I'm working on a new small project that looks like part of Entreprise Sample. I find this WIP enterprise tutorial branch aims to render in v2 frame.

Maybe I can help with this tutorial during my coding. my project needs several pallets like DID, registrar and rbac. I'm planning to start by adapting them to the new v2 frame. Do you have any suggestions for me to do this? Thx.

Use kickstart to easily create how-to guides from the CLI.

E.g:

• Title?
• Goal?
• Use cases?
• Overview?
• Steps?

Note: this is a future feature, kickstart is a cool tool but still has a few bugs.

Adding some new guides:

• [x] Simple origin guide: how to assign accountId to a custom origin
• [ ] Multiple origins: create a custom origin to handle multiple origin types
