habtm in rails 4.1

[markmcdonald51]

Hi,

I am trying to use the habtm feature of rails in activescaffold. I didnt think this would be so troublesome and at this point i am not sure if i am finding a bug or not doing something right in AS. So i have a very simple model that has a habtm like such...

class MultinationalCompany < ActiveRecord::Base
has_and_belongs_to_many :stock_exchange_countries
end

When i try to list (or do anything with this AS controller now I get:

Showing /home/mark/.rbenv/versions/2.1.3/lib/ruby/gems/2.1.0/gems/active_scaffold-3.4.11/app/views/active_scaffold_overrides/_list_record.html.erb where line #12 raised:

undefined method `multinationalcompanies_stock_exchange_countries' for #MultinationalCompany:0x007f17798182f0

undefined method `multinationalcompanies_stock_exchange_countries' for #MultinationalCompany:0x007f17798182f0

<% columns.each do |column| %> <% authorized = record.authorized_for?(:crud_type => :read, :column => column.name) -%> <% column_value = authorized ? get_column_value(record, column) : active_scaffold_config.list.empty_field_text -%> <%= content_tag :td, column_attributes(column, record).merge(:class => column_class(column, column_value, record)) do %> <%= authorized ? render_list_column(column_value, column, record) : column_value %>

I know this works because i can add items to the habtm tables via console. Just not sure why AS is looking for a method like this.

Thanks in advance.

What is your active_scaffold config block in that controller? It seems like trying to display multinationalcompanies_stock_exchange_countries column instead of stock_exchange_countries

[markmcdonald51]

Hi Sergio,

this one is pretty simple actually...it looks to be getting the
tableize/constantize mixed up as if this was going to be a method like
the error states shouldn't it be 'multinational_companies_stock_exchanges'
and not multinationalcompanies? I fished around a bit with the stacktrace
and went into the gem trying to look for where this takes place but decided
not to get to deep...

class MultinationalCompaniesController < ApplicationController

active_scaffold :"multinational_company" do |config|
config.label = 'Multinational Companies'
config.columns.exclude(:shareholder_relationships, :created_at,
:updated_at)

   # trying different things here but they are commented out because it

makes no diff....
# :stock_exchange_countries, :stock_exchanges,
# config.columns[:stock_exchange_countries].form_ui = :multi_select

end
end

Try to exclude :multinationalcompanies_stock_exchange_countries column
Rails 4.1 changes internal of habtm, it works like a has_many through with a new has_many with intermediate model. multinationalcompanies_stock_exchange_countries column can be that association created by ActiveRecord.

I haven't used ActiveScaffold with Rails 4.1 yet because of some rails 4.1 bug, I have only tested against rails 4.1 with some automated tests, although many features are not tested yet. Maybe that internal association will be excluded by default in the future.

[markmcdonald51]

Good call Scambra! That worked. Now if i could just figure out how to create a multi-select out of this i would be in business! I already tried the form_ui = :multi_select (from the api) but it didnt seem to work.

I excluded these:

:multinationalcompanies_stock_exchange_countries)

config.columns.exclude( :multinationalcompanies_stock_exchanges,
:multinationalcompanies_stock_exchange_countries)

and it worked.... then added:

   config.columns[:stock_exchange_countries].form_ui = :select
   config.columns[:stock_exchanges].form_ui = :select

and i at least get the checkboxes for the ui. Just wish i could have multiselect which is a rather useful form ui for this cause.

THanks for all you help, again Scrambra!

cheers

There is no :multi_select form_ui. There is a :multi_select search_ui but it's displayed as checkbox list too, and it's only for singular associations where you want to allow searching for multiple values.

You can enable draggable lists with:

config.columns[:stock_exchanges].options = {:draggable_lists => true}

It's not the same but it's better than checkboxes. Also, you can create your own override for that column in your helper. Or create your own form_ui in ApplicationHelper, named like active_scaffold_input_multi_select(column, html_options)
