Posted in How to deposit, withdraw, transfer coins...

Hi Chris,

I want to create an app where I can keep track of my cryptocurrencies.

This is what I have right now:

  • Coins (can have many wallets)
    • name
    • symbol

  • Wallets (belongs_to coin)(has_many transactions)
    • coin_id
    • name
    • wtype (Type of wallet, Hardware, Exchange, Local, ‚Ķ)
    • address
    • balance
    • description

  • Transactions(belong_to wallet)
    • date
    • txid (Transaction ID) this should be generated when the transaction is saved to the DB. (SecureRandom.hex 32)
    • wallet_id
    • txtype (Transaction Type: Deposit, Withdraw, Transfer)
    • amount
    • amount_currency
    • description
    • old_balance (should take the actual balance from the wallet)
    • new_balance (should calculate the new balance¬† old_balance + amount)

The creation of coins and wallets is no problem.

Im stuck at the transaction part, the deposit and withdraw part.

Where would you put the deposit, withdraw and the transfer methods?

If you need more infos, let me know.

Posted in Switch state of boolean field

Hi Chris,

i got it working.
Is this OK or is there a better way to implement this?

my routes

resources :products do
    member do
        patch :toggle_enable_status
    end
end

products_controller.rb

def toggle_enable_status
    @product.toggle!(:enabled)
end

the link in index.html.erb

<td class="product-<%= product.id %>">
    <%= link_to "#{ product.enabled ? 'Enabled' : 'Disabled' }", toggle_enable_status_product_path(product), method: :patch, remote: :true, class: "btn btn-xs btn-#{ product.enabled ? 'success' : 'warning' }"  %>
</td>

and the toggle_enabled_status.js.erb

console.log(<%= @product.enabled %>);
<% if @product.enabled == true %>
    $(".product-<%= @product.id %> > a").html('Enabled').removeClass('btn-warning').addClass('btn-success')
<% else %>
    $(".product-<%= @product.id %> > a").html('Disabled').removeClass('btn-success').addClass('btn-warning')
<% end %>
$("#product-status-<%= @product.id %>").html("<%= @product.enabled %>")

Posted in Autocomplete a form field

Hi Chris,

thanks for your reply.
I will try your suggestion.

Posted in Autocomplete a form field

Hi,

i have the following models:
users, markets, assignments, products, sales,

a user gets an assignment, and then he should enter his sales for the assignment.

i have a sales form with the following fields:

quantity, product, price

now i want to autocomplete the product_field with the products from the product model.
only products that are in the database, no new products should get over the sales form.

Any hint how to start this?

thanks
