2 solid days of time and I can’t figure this/find answer in previous
group post/find answer via google anything that works. I know the
problem is me (and I will know doubt kick myself later) but if anyone
could direct me I’d appreciate it.
I have items (called ‘WeeeItems’) in one place that need to be
delivered somewhere else. When they get delivered we need a ‘transfer
note’, (called ‘WeeeTransfer’). So, I need to create a new transfer
note recording the destination,date etc and select items from a list
of existing stock that are included with that transfer.
I’ve got forms and things working to add items into the
‘WeeeItems’ (our stock waiting to transfer), but I can’t figure how to
include given weeeitems with a specific transfer. Trying to keep
things as simple as possible while I figure what I’ve got wrong
(normally helps!) I’m finding I don’t know how to refer to the
weee_items_id of the related table. As such, the view detailed below
will NOT add anything to the transfer table failing with:
NoMethodError in WeeeController#confirmtransfer
You have a nil object when you didn’t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.save
So, I think this means I need a form field that references 1 or more
WeeeItems, I just don’t know how to do that. I thought along the
but that and variations haven’t worked so far.
Any direction greatly appreciated.
class WeeeTransfer < ActiveRecord::Base
#belongs_to is in the other model
@transfer = WeeeTransfer.new(params[:transfer])
if request.post? and @weeetype.save
flash[:notice] = ‘WEEE Transfer added’
redirect_to :action => ‘index’
#this bit will get us all the UNtransfered weee items #i will eventually use this to have list of check boxes for items
included in the transfer
#but it’s not used yet… is that my problem?
@tableweees = WeeeItem.find(:all, :include => “weee_type”,
:conditions => “weee_transfers_id is null”)
<% form_for :transfer do |f| %> Weee Destination: <%= f.text_field :weeetransferdestination %><br /
Transfer Type: <%= f.text_field :weeetransfertype %><br /> Transfer Date: <%= f.text_field :weeetransferdate %><br /> <%= submit_tag %> <% end %>
