I have a table-plus displaying the rows of a table. I'd like to put a
button on each row that posts an ajax request to update a few fields
in the row, then redisplay it. It sounds easy but I just can't get it to work.
Here's my first attempt:
<page title="Signups">
<content:>
<section class="content-body">
<table-plus fields="this, first_name, last_name">
<empty-message:>No signups match your criteria</empty-message:>
<controls:>
<div part="part-#{this.id}">
<update-button label="Activate"
params="&{:first_name=>'heidy'}" update="self"/>
</div>
</controls:>
</table-plus>
</section>
</content:>
</page>
This fails to render. Dryml complains:
invalid part="part#{this.id}" attribute on <div>
Any idea how I can render 45 different parts, one for each row?
So I tried updating the entire table instead:
<page title="Signups">
<content:>
<section class="content-body">
<table-plus fields="this, first_name, last_name" part="signups-table">
<empty-message:>No signups match your criteria</empty-message:>
<controls:>
<div part="part-#{this.id}">
<update-button label="Activate"
params="&{:first_name=>'heidy'}" update="signups-table"/>
</div>
</controls:>
</table-plus>
</section>
</content:>
</page>
This renders, and when I click the button, the action does happen.
However, when Hobo tries to render the response, it throws:
NoMethodError in SignupsController#update
undefined method `member_class' for <Signup:0xb1f7a380>
/vendor/rails/activerecord/lib/active_record/attribute_methods.rb:260:in

`_tag_context'
/vendor/plugins/hobo/hobo/lib/hobo/dryml/template_environment.rb:248:in
`new_context'
Any ideas on what I can try next? I'd really like to get this working.

P.S.
On the second attempt, maybe Hobo is trying to render the entire table,
except it's only setting the context to the record that was used to render
the one row? The parameters would indicate this:
{"page_path"=>"signups/index", "render"=>{"0"=>{
"id"=>"signups-table",
"part_context"=>"BAhbCDoS...--050f09e43...\n"}},
"signup"=>"",
"id"=>"16",
"first_name"=>"heidy"}
I tried resetting the context to the full table, with="&this_parent":
<update-button with="&this_parent" label="Activate"
params="&{:first_name=>'froufrou'}" update="signups-table"/>
But this fails during render:
undefined method `reverse_reflection' for NilClass:Class
vendor/plugins/hobo/hobo/lib/hobo/hobo_helper.rb:64:in `object_url'
vendor/plugins/hobo/hobo/taglibs/rapid_forms.dryml:482:in `update_button'
vendor/plugins/hobo/hobo/lib/hobo/dryml/template_environment.rb:326:in
`_tag_context'
vendor/plugins/hobo/hobo/lib/hobo/dryml/template_environment.rb:267:in
`new_object_context'
Model and controller are totally straightforward:
class Signup < ActiveRecord::Base
hobo_model # Don't put anything above this
fields do
first_name :string
last_name :string
end
def create_permitted?; true; end
def update_permitted?; true; end
def destroy_permitted?; true; end
def view_permitted?(field); true; end
end
class SignupsController < ApplicationController
hobo_model_controller
auto_actions :all
end
