Rails: undefined local variable or method `tenant' for #<ActionView::Base:> - ruby-on-rails

Question

I'm currently trying to render a partial with errors messages if when a form submission fails to create a tenant instance. Im using locals as described in the Rails documentation to pass variables to a partial.
controllers/tenants_controller.rb
def new
#unit = Unit.find(params[:unit_id])
#tenant = Tenant.new
end
def create
#unit = Unit.find(params[:unit_id])
#tenant = #unit.tenants.new(tenant_params)
if #tenant.save
redirect_to #tenant
else
Rails.logger.error('Unable to save Tenant')
render 'new'
end
end
In here im redirecting to the new template if the #tenant fails to be created. This should be adding errors to the #tenant
tenants/new.html.erb
<div class="py-6">
<div class="max-w-7xl mx-auto px-4 sm:px-6 md:px-8">

Here im passing tenant variable via the locals however it doesn't seem to be passing the variable to the partial errors in the line <%= render 'errors', locals: { tenant: f.object } %>
When the errors partial is rendered an error is raised.

<% if tenant.errors.any? %>

Any idea why
undefined local variable or method `tenant' for #<ActionView::Base
is being raised?

Answer 1

You are calling render incorrectly.
You have two options. You can call it like this:
<%= render partial: 'errors', locals: { tenant: f.object } %>
or like this:
<%= render 'errors', { tenant: f.object } %>
