Been experimenting with this for a while and still getting an error.
Any thoughts much appreciated.

Here's the line and stack trace.

@table = ModelA.report_table(:all, :only =>
[:id, :name], :include => {:model_b => {:only => [:name], :include =>
{:model_c => {:only => [:name], :include => :model_d }}}})

Just another quick question on this.

In the example where:

model_a has many model_b through model_c

Do you need to include model_c?

Thanks,

Tim

Hi Andrew,

This is exactly what I was looking for and points me back in the right
direction.

My question about the id's stems from the use of it in various
examples that I may have been reading too much in to. It was looking
like you'd need to ensure the id column was present if it was to be

Hi Tim,
Model_c is not a relation on model_a, you want a nested include:
And if you wanted model_d:
Don't ask for the model_d and model_c relations from model_b at the same
level as it will cause duplicates (see many previous messages on list).
I'm afraid you'd actually have to give the exception message and a few

Table data manipulation/copying columns - simple question... I think

2009-06-11T04:17:43Z

Hi,

I'm new to this and though I think this is a simple operation, I can't
find the answer here or in the documentation.

What is the best way to take two columns from a Table and copy them to
a new Table. E.g. Table 1 has columns a,b,c,d with data, I want to
create a new Table, Table 2, with two columns equal to b and d from

Hi,

I have a fairly complex domain that I am trying to report on and am
having
difficulty with report_table.

But, my basic question is about the general use of :include.

model_a has many model_b
model_b has many model_c
model_b has many model_d through model_c

When I do:
model_a.report_table(:all, :include => [:model_b])

well, this works (nesting). thanks! one note, i get some warnings

thanks, andrew. i would have replied sooner, but i was offline all
weekend. i'll test this today.

ftr, i'm using ar 2.3.2

the third strangeness was just pointing out that if i only include one
model, it works as expected.but if i do the equivalent of a 'where'
clause by using :conditions, that the same duplication of records

I think the behaviour is correct because you are including 'events'
twice via the HABTM :through. You would probably want a nested include:
{:events => {:only => :id}}}}
Acts As Reportable has no SQL knowledge it just walks the ActiveRecord
object graph so it doesn't know that the two separate associations go to

i don't see much of what you've written--it looks like there's
supposed to be code here?

but guessing from what appears in your post, it looks like what you
want is:

Ruport::Controller if you're trying to use a model that inherits
Ruport's controller class. or, if you just want a report, you use

hi all,

i'm getting some strangeness w/ acts_as_reportable. short question: is
there a way to ensure a query is only run once? see below for why i
ask: (btw, although this is a longish question, i only put in relevant
info)

assume 3 models
Event, has_many :members, :through => :registrations AND
