Added associations but don't see generated methods

Hi Fred,

I posted four files for easier viewing, I will also post details
below, though I find reading them unattractive.

The code in question (I thought) was in app\views\expenses
\new.html.erb, specifically the lines:
<%# New version of vendor selection -%>
<% @vendors = Vendor.find( :all, :order=>“nickname ASC”) -%>
<%= f.collection_select(:vendor_id, @vendors, :id, :nickname) %>
<%# NOTE: first argument, symbol :vendor, does not produce an
error here either -%>
<%# End of New version -%>
You may download the file in its entirety from

However, the output from the crash indicates the failure was in line
44 of the controller,
app\controllers\expenses_controller.rb
The code in the neighborhood around line 44 is:

GET /expenses/1/edit

def edit
@expense = Expense.find(params[:id])
end

POST /expenses

POST /expenses.xml

def create
debugger # <== Line 44
@expense = Expense.new(params[:expense])

respond_to do |format|
  if @expense.save
    flash[:notice] = 'Expense was successfully created.'
    format.html { redirect_to(@expense) }
    format.xml  { render :xml => @expense, :status

=> :created, :location => @expense }
Apparently, the crash display-logic doesn’t think the “debugger” line
merits a line number.
You can download the controller in its entirety from:

The dump from the crash is shown below. It strikes me as fairly ugly,
so I did screen captures which may be download from:

(My screen-capture utility doesn’t support scrolling, so I had to take
two images.)

Incidentally, the crash dump includes a display of params[:expense],
which includes “vendor”=>“65”. That’s what I’ve been trying to get,
i.e. the vendor field is now populated with the vendor::id of the
vendor I selected in the drop-down, rather than the vendor:nickname
that I used to get. Hooray!!

I hope you can define a cause for my current crash. I can’t.

Best wishes,
Richard

Incidentally, the crash dump includes a display of params[:expense],
which includes “vendor”=>“65”. That’s what I’ve been trying to get,
i.e. the vendor field is now populated with the vendor::id of the
vendor I selected in the drop-down, rather than the vendor:nickname
that I used to get. Hooray!!

Are you absolutely certain that the trace you show is as a result of
the code you have posted? I would have expected the vendor id value
(65) to be passed in vendor_id in params not vendor, as that is what
you have put in your collection_select. Have a look at the html
generated by the collection_select and see if that looks right.

Before I start, let me mention that I have posted a Microsoft Word
document of the following response, along with two relevant files of
the app here:

You may wish to download some or all for reference purposes of ease of
reading.

Are you absolutely certain that the trace you show is as a result of the code you have posted?
No. When I originally ran the app (and when I ran it just now), I
had expense\new.html.erb set with:
<%# New version of vendor selection -%>
<% @vendors = Vendor.find( :all, :order=>“nickname ASC”) -%>
<%= f.collection_select(:vendor_id, @vendors, :id, :nickname) %>
<%# NOTE: first argument, symbol :vendor, does not produce an
error here either -%>
<%# End of New version -%>

Because of “vendor_id” in the collection_select, I get;
NoMethodError in Expenses#new

%>
14: <%# NOTE: first argument, symbol :vendor, does not produce an

16:

But I had originally run it with (and just now changed it to):

<%# New version of vendor selection -%>
<% @vendors = Vendor.find( :all, :order=>"nickname ASC") -%>
<%= f.collection_select(:vendor, @vendors, :id, :nickname) %>
<%# NOTE: first argument, symbol :vendor, does not produce an

error here -%>
<%# End of New version -%>
where I went back to :vendor (and removed “also” from my comment.

I had changed to vendor_id because that’s what Frederick C.
suggested, but I apparently changed it after I encountered the error
in the Expense controller.

Now with the change back to :vendor and clicking the “Reload current
page” icon in Firefox, the Expense\new.html.erb pages is displayed
without error. From there I click the down arrow in the item
immediately below the Vendor tag and select the item with the vendor
nickname “vendor 7/12/2010-1623” and populate the rest of the fields.

Then when I click Create, I get the error display:

For some reason, this above dump does not display line 45 nor its
context. But the relevant portion of app\controllers
\expenses_controller.rb is shown here:

POST /expenses

POST /expenses.xml

def create
debugger
@expense = Expense.new(params[:expense]) # <== Line 45

respond_to do |format|
  if @expense.save
    flash[:notice] = 'Expense was successfully created.'
    format.html { redirect_to(@expense) }
    format.xml  { render :xml => @expense, :status

=> :created, :location => @expense }
else
format.html { render :action => “new” }
format.xml { render :xml => @expense.errors, :status
=> :unprocessable_entity }
end
end
end

I note that the params[“expense”][“vendor”]=>“65”, which I view as
almost perfect, i.e. it’s a vendor ID as opposed to a vendor
nickname. But is it the ID matching my selection?

It is indeed, as witnessed by the fact:

I hope you can see what’s wrong here. Maybe I should just rebuild the
Expense portion in its entirety, now that I’m so close to getting the
ID of a selected vendor to appear ready to be saved in new expense
records.

Best wishes,
Richard

This is precisely the error you’ll get if you put :vendor (the name of
the association) rather than :vendor_id (the name of the attribute).
There’s a section explaining why this happens in the form helpers guide
(at guides.rubyonrails.org )

OK Guys,

I think I understand the problem now. We’ve got to populate the join-
table with the ID of the new Expanse record and the ID of the selected
Vendor record.

Heretofore, I thought using vendor instead of Fred’s vendor_id was
cool because:

  1. It didn’t crash the new Expense record
  2. It populated the Expense vendor field with the ID of the selected
    vendor.

Only now do I see that our goal is to populate the join-table. My
idea of qualifying vendor_id as expenses_vendor/:vendor didn’t fly.
But you guys sound like you’ve got enough experience in Rails to see
through this problem. I keeping my fingers crossed.

27

Hey Guys,

How about this idea.

  1. We revert to vendor as the first arg to collection_select.
  2. That populates params[“expense”][“vendor”] with the selected
    vendor’s ID
  3. We create an observer on the Create button
  4. In the observer, we create a new join record and populate it
    with:
    a. The new Expense record’s ID
    b. The selected vendor’s ID
    c. Save the the join record.

Ideally, that’s what collection_select would do for us if we could
invoke it in just the right way.

Any votes in favor of this idea?

Best wishes,
Richard

Hey Fred and Colin,

I presume you have got a vendor_id column in the expenses table?

No, I don’t. I thought that’s the kind of thing was generated
dynamically. But now that you ask, I see that dynamic generation of
methods would extend to the addition of columns to tables

On second thought, vendor_id should be in the join_table, not in the
expense_table. And that’s true:

.mysql> show columns in expenses_vendor;
±------------±---------±-----±----±--------±------+
| Field | Type | Null | Key | Default | Extra |
±------------±---------±-----±----±--------±------+
| expenses_id | int(11) | YES | | NULL | |
| vendor_id | int(11) | YES | | NULL | |
| created_at | datetime | YES | | NULL | |
±------------±---------±-----±----±--------±------+
3 rows in set (0.31 sec)

So why does:
<%# New version of vendor selection -%>
<% @vendors = Vendor.find( :all, :order=>“nickname ASC”) -%>
<%= f.collection_select(:vendor, @vendors, :id, :nickname) %>
<%# NOTE: first argument, symbol :vendor, does not produce an
error here -%>
<%# End of New version -%>
fail when I use vendor_id as the first argument of collection_select,
i.e.

Could it be I need to add some path of sorts in front of vendor_id,
e.g. expenses_vendor/vendor_id.

Just grasping at straws here. Is there any solution to my dilemma?

Best wishes to you both,

In stead of the observer idea, how about switching to an option
containing the link-record creation/population with the caveat that
the join-table be checked for the existence of a join-record for the
current expense-record ID, offering to overwrite the existing link or
canceling the new-link request.

That sounds pretty simple. Any fans of this idea?

Best,
Richard

Hey Fred and Colin,

I presume you have got a vendor_id column in the expenses table?

No, I don’t. I thought that’s the kind of thing was generated
dynamically. But now that you ask, I see that dynamic generation of
methods would extend to the addition of columns to tables

They aren;t

On second thought, vendor_id should be in the join_table, not in the
expense_table. And that’s true:

Wrong. You’ve got a belongs_to/has_many so there is no join table.

NoMethodError in Expenses#new

Showing app/views/expenses/new.html.erb where line #13 raised:

undefined method `vendor_id’ for #Expense:0x47fa518

Because Expense doesn’t have a vendor_id method since you haven’t
added that column to it. I’d recommend having another read of

I am sorry Richard I have completely lost track of what you are trying
to do, and have no idea what the relationships between your models is.
Have you worked through Rails Guide on Active Record Relationships?
I mean worked through it and understood all the concepts there, and
experimented with the code there to see how it all works. If not then
I suggest you do it. Then do the same for the other guides there.

When you have done that then hopefully you will have a better idea of
how to organise your relationships and what fields you need to put in
the tables.

Then I suggest you work right through some tutorials, I like the one
at http://railstutorial.org/. The one in Agile Development with Rails
is also excellent.

When you have done the above then you should have a much better idea
of the basics or Rails. If you still have problems then come back
again, with a new thread, and try again.

OK Fred and Colin,

Problem solved: Throw away the join table; add a vendor_id column to
the expense table; use vendor_id in the collection_select method.

This has been a thorn in my side for a long time. I’m so relieved to
learn the way out of my dilemma.

Best wishes,
Richard
