Description
I am currently getting this alert error in the browser when I click the input checkbox:
"An error occured. Please contact the System Administrator"
```
20:12:06.347 [error] Drab Handler failed with the following exception:
** (ArgumentError) assign @changeset not available in eex template.
Please make sure all proper assigns have been set. If this
is a child template, ensure assigns are given explicitly by
the parent template as they are not automatically forwarded.
Available assigns: [:action, :conn, :parent, :po_grantotal, :type, :view_module, :view_template]

```
**Mi current configuration:**
Drab 0.10.0
Phoenix 1.3.4
Phoenix_html 2.12.0 (currently locked due to fetch_assign/2 issue)
**This is the code:**
**The commander (payment_order_commander.ex):**
```
defmodule EprWeb.PaymentOrderCommander do
use Drab.Commander
defhandler invoice_selected(socket, _sender) do
poke socket, po_grantotal: 1000 * 1
end
end
```
**The controller (payment_order_controller.ex):**
```
defmodule EprWeb.PaymentOrderController do
........
def new(conn, _params, %Epr.Debts.Contract{} = document) do
invoices = Epr.Debts.list_unpaid_invoices(document)
changeset =
%PaymentOrder{}
|> Payments.new_payment_order()
render(
conn,
"new.html",
changeset: changeset,
parent: document,
invoices: invoices,
bank_accounts: Epr.Payments.list_all_bank_accounts(),
currency_us: document.currency_us,
po_grantotal: 0,
type: "contract"
)
end
end
```
**The main template (new.html.drab):**
This template is the one the controller renders. I tried using the eex extension instead of drab and experience the same error.
```
Nueva orden de pago
render "form.html", Map.put(assigns, :action, contract_payment_order_path(@conn, :create, @parent))
```
**The form (form.html.drab):**
```
<%= form_for @changeset, @action, fn f -> %>
<%= render "_invoices.html", conn: @conn, invoices: @invoices, parent: @parent %>
.......
<% end %>
```
**The first partial (_invoices.html.drab)**
```
...........
<%=
case @parent do
%Epr.Partners.Provider{} ->
for i <- @invoices do
render "_invoice_details.html", invoice: i, currency: i.currency_us
end
_ ->
for i <- @invoices do
render "_invoice_details.html", invoice: i, currency: @parent.currency_us
end
end
%>
.........
```
**The second partial (_invoice_details.html.drab):**
This partial has the input checkbox and drab-change event handeler.
```
<%= @invoice.proforma_invoice_number %>
<%= @invoice.exempt_order_number %>
<%= @invoice.invoice_number %>
<%= @invoice.date %>
........
```
Thanks in advance for the help.
Best regards.
Contributor guide
Research direction
Reproduce the checkbox interaction and trace the failure from lib/drab/live.ex through the payment_order templates, especially form.html.drab and new.html.drab. Compare the assigns passed into the partials with the missing @changeset reported by phoenix_html; done means the interaction rerenders without the missing-assign ArgumentError.
