has_many and belong_to association not working

I have two models.  call.rb which has_many :visits and visit.rb which
belongs_to :call.  After populating call from the form which then
shows all the parameters including the call.id I then make a visit
corresponding to the call.  the form for the new visit creates a new
record ok and shows the input information except for I have it show me
the call_id which is the foreign key and it tells me that it is nill
when I look at the record in the ruby console.  So it never associates
the visit with the corresponding call.
my call.rb is as follows

class Call < ActiveRecord::Base
    ALL_FIELDS = %w(name address age area sex notes)
    VALID_SEX = ["Male", "Female"]
    validates_presence_of :name, :address, :age, :area
    validates_inclusion_of :sex,
                            :in => VALID_SEX,
                            :message => "must be male or female"
    has_many :visits, :foreign_key => ''call_id''

end
the visit.rb is as follows

class Visit < ActiveRecord::Base
    belongs_to :call, :class_name => ''Call'', :foreign_key
=> ''call_id''
end

my CallsController is

class CallsController < ApplicationController

  def index
    @call = Call.find(:first, :order => ''RANDOM()'')
  end

  def new
    @call = Call.new
  end

  def create
    @call = Call.new(params[:call])
    if @call.save
      flash[:notice] = "Call submission succeded"
      render :action => ''show''
    else
      render :action => ''new''
    end
  end

  def show
    @call = Call.find(params[:id])
  end
end

My visits controller is

class VisitsController < ApplicationController

  def index
  end

  def show
    @visit = Visit.find(params[:id])
  end

  def new
    @visit = Visit.new
  end

  def create
    @visit = Visit.new(params[:visit])
    if @visit.save
      flash[:notice] = "Visit submission succeded"
      render :action => ''show''
    else
      render :action => ''new''
    end
  end

end
And my schema after migrations is
ActiveRecord::Schema.define(:version => 6) do

  create_table "calls", :force => true do |t|
    t.string   "name"
    t.string   "address"
    t.string   "age"
    t.string   "area"
    t.date     "date"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "sex",        :default => "Male"
    t.text     "notes"
  end

  create_table "visits", :force => true do |t|
    t.integer  "call_id"
    t.datetime "created_at"
    t.datetime "updated_at"
    t.string   "name"
    t.string   "address"
    t.date     "date"
    t.string   "placement"
    t.string   "time_of_day"
    t.text     "topic"
    t.text     "next_topic"
  end

end

Any help for a noob will be much greatly appreciated

Re: has_many and belong_to association not working

"I think make a visit corresponding to the call" is a little
nebulous.  How are you doing that?

Re: has_many and belong_to association not working

Thanks for your reply

What is happening is that I create a call with a form from my new
action in my ViewsController and enter information such as name and
address.  Then I execute the show action to view the entered data.
The show view then has a button which I click to create a visit for
that call (each call has_many visits).  The show view for the call
controller does show also the call.id so I know it exists.
Then when the New action for the VisitsController is executed a new-
visit form is opened in which I enter information for the visit that
belongs_to that call.  I enter information such as placement, topic
etc.  then I execute the show action for the VisitsController and it
displays the information and the flash notice showing that the visit
was sucessfully created.  I try to also display call_id which is the
foreign key for the visit but it displays nothing and when I check the
values for the visit record in the ruby console it tells me that the
value for call_id is nil.  I hope this explains it better.  This is my
first rails project so any help would be greatly appreciated.

Re: has_many and belong_to association not working

Can you get the associations to work at the console?

FWIW--that foriegn_key arg on the has_many looks weird to me--it''s the
child tables that get FKs, not the parent.  And at any rate, you''re
following the rails conventions there, so you shouldn''t have to specify
those explicitly (ditto on the :class_name arg).

Re: has_many and belong_to association not working

Thanks for the reply

In fact I changed the models back to

class Call < ActiveRecord::Base
    has_many :visits
    ALL_FIELDS = %w(name address age area sex notes)
    VALID_SEX = ["Male", "Female"]
    validates_presence_of :name, :address, :age, :area
    validates_inclusion_of :sex,
                            :in => VALID_SEX,
                            :message => "must be male or female"


end

And

 class Visit < ActiveRecord::Base
    belongs_to :call
end


But the association does not work in the console
When I create a new visit from the show action  link in my
calls.view.show.rhtml to new visit I go to the form for the
new visit and populate it with values.  I try to display the call_id
and get nothing though it displays my other entered fieds.  Then when
I go to the ruby console to check
the values of the new visit record  the value of the foreign key
call_id is nil.  So I am not
sure why this is so.  When I do the show page from the call views I
display the call.id for
the call and it has the proper id but it never gets over to the
call_id column in the new
visit I make.  The association doesn''t get the call_id.  I am sorry
I,m such a noob but this is my first rails app   I have all the books
and
have done a few screecasts but am stuck here
Thanks for your help

Re: has_many and belong_to association not working

Well--let''s leave the views out of the picture for a sec.  Can you do
something like:
> my_call = Call.find(:first)
> my_call.visits.count # <- we want one w/a count of 0
> my_visit = Visit.find(:first)
> my_call.visits < my_visit
> my_call.save
> my_call.visits.count # <- does this return ''1''?
> my_call.id == my_visit.call_id # <- do we get a ''true''
here?
If that works, I think you can say your association is in fact working,
and we can start dissecting your views.

Subject: [Rails] Re: has_many and belong_to association not working


Thanks for the reply

In fact I changed the models back to

class Call < ActiveRecord::Base
    has_many :visits
    ALL_FIELDS = %w(name address age area sex notes)
    VALID_SEX = ["Male", "Female"]
    validates_presence_of :name, :address, :age, :area
    validates_inclusion_of :sex,
                            :in => VALID_SEX,
                            :message => "must be male or female"


end

And

 class Visit < ActiveRecord::Base
    belongs_to :call
end


But the association does not work in the console When I create a new
visit from the show action  link in my calls.view.show.rhtml to new
visit I go to the form for the new visit and populate it with values.  I
try to display the call_id and get nothing though it displays my other
entered fieds.  Then when I go to the ruby console to check the values
of the new visit record  the value of the foreign key call_id is nil.
So I am not sure why this is so.  When I do the show page from the call
views I display the call.id for the call and it has the proper id but it
never gets over to the call_id column in the new visit I make.  The
association doesn''t get the call_id.  I am sorry
I,m such a noob but this is my first rails app   I have all the books
and
have done a few screecasts but am stuck here Thanks for your help On Jun

Re: has_many and belong_to association not working

Okay then--cool.  And if I follow the earlier stuff, the view-mediated
Visit create process is not in question, right?  It''s just the bit
where
you create a Call from off a visits/show view?  The resulting call does
not have the proper Visit reference?  (And have you confirmed this by
looking in your db?)

If that''s all right--how are you kicking off the process of creating a
new Call from your visits/show view?  I''m guessing a link_to call?
Let''s see that to start please.

Re: has_many and belong_to association not working

Thanks again for the reply

Actually its the other way around each call has many visits and each
visit belongs to one call.
I create the call first and populate the form and it then shows me in
the ruby console
that all the fields are populated (the call.id, call.name,
call.address, etc)
Then what I try to do is create a new visit form that call (it has
further info and later I want to create new visits for that call)

On each calls.show.rhtml page I show some of what I entered and there
is link to create a new visit for that call that links to the new
action of the visits controller.  This is where I want the association
to take place.  It should take the call.id from the call and make it
the visits.call_id for that visit.

here is the views.calls.show.rhtml code

<h2><%= @call.name %></h2>
<p><%= @call.address %></p>
<p><%= @call.area %></p>
<p><%= @call.date %></p>
<p><%=-wfOwKlo/SGM@public.gmane.org %></><br />
<%= link_to ''New Visit'', :controller =>
"visits", :action =>
"new", :call_id => @call.id %>
<p><%= debug(params) %></p>

which opens a form for a New Visit

And here is the views.visits.new.rhtml

<%= error_messages_for ''visit'' %>
<% form_for @visit do |f| %>

<p>
    date:<br />
    <%= date_select ("post", "date") %>
</p>

<p>
    placement:<br />
    <%= f.text_field :placement %>
</p>
<p>
    time of day:<br />
    <%= f.text_field :time_of_day %>
</p>
<p>
    topic:<br />
    <%= f.text_field :topic %>
</p>
<p>
    next topic:<br />
    <%= f.text_field :next_topic%>
</p>

<p>
    <%= f.submit "Create" %>
</p>
<p>
<%= debug(params) %>
</p>

<% end %>

When I check in the ruby console It show the record having been
populated except fot the visit.call_id which it records as nil.  So it
is not getting the call.id from the call

Thanks again so much for your help

Re: has_many and belong_to association not working

Ah, okay then.  So this 

  <%= link_to ''New Visit'', 
              :controller => "visits", 
              :action => "new", 
              :call_id => @call.id %>

Should bring us over to VisitsController.new().  I would expect that
code to look something like:

  def new
    @visit = Visit.new
    @visit.call_id = params[:call_id]  # <- is something like this line
here?
    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @project }
    end
  end

How close is that?

Thanks again for the reply

Actually its the other way around each call has many visits and each
visit belongs to one call.
I create the call first and populate the form and it then shows me in
the ruby console
that all the fields are populated (the call.id, call.name,
call.address, etc)
Then what I try to do is create a new visit form that call (it has
further info and later I want to create new visits for that call)

On each calls.show.rhtml page I show some of what I entered and there
is link to create a new visit for that call that links to the new
action of the visits controller.  This is where I want the association
to take place.  It should take the call.id from the call and make it
the visits.call_id for that visit.

here is the views.calls.show.rhtml code

<h2><%= @call.name %></h2>
<p><%= @call.address %></p>
<p><%= @call.area %></p>
<p><%= @call.date %></p>
<p><%=-wfOwKlo/SGM@public.gmane.org %></><br />
<%= link_to ''New Visit'', :controller =>
"visits", :action =>
"new", :call_id => @call.id %>
<p><%= debug(params) %></p>

which opens a form for a New Visit

And here is the views.visits.new.rhtml

<%= error_messages_for ''visit'' %>
<% form_for @visit do |f| %>

<p>
    date:<br />
    <%= date_select ("post", "date") %>
</p>

<p>
    placement:<br />
    <%= f.text_field :placement %>
</p>
<p>
    time of day:<br />
    <%= f.text_field :time_of_day %>
</p>
<p>
    topic:<br />
    <%= f.text_field :topic %>
</p>
<p>
    next topic:<br />
    <%= f.text_field :next_topic%>
</p>

<p>
    <%= f.submit "Create" %>
</p>
<p>
<%= debug(params) %>
</p>

<% end %>

When I check in the ruby console It show the record having been
populated except fot the visit.call_id which it records as nil.  So it
is not getting the call.id from the call

Thanks again so much for your help

Re: has_many and belong_to association not working

Thank you again Roy.  Actually Roy my whole visits controller is

class VisitsController < ApplicationController

  def index
  end

  def show
    @visit = Visit.find(params[:id])
  end

  def new
    @visit = Visit.new
  end

  def create
    @visit = Visit.new(params[:visit])
    if @visit.save
      flash[:notice] = "Visit submission succeded"
      render :action => ''show''
    else
      render :action => ''new''
    end
  end

end


So this is most likely where I am having trouble

Re: has_many and belong_to association not working

I think you''re right.  Your link_to call is passing the id of the
current call to your visit controller in a parameter called :call_id.
You can retrieve it out of the params hash in the same way that your
show method pulls :id out.  But right now you''re not doing that.  Try
adding this line under your @vist = Visit.new call:

  @visit.call_id = params[:call_id]

Any better?

Cheers,

-Roy

Re: has_many and belong_to association not working

I''m sorry Roy I am not sure where to put that line - after @visit
Visit.new in the new action of the VisitsController
or do I replace the new action with what you had above

def new
    @visit = Visit.new
    @visit.call_id = params[:call_id]  # <- is something like this
line
here?
    respond_to do |format|
      format.html # new.html.erb
      format.xml  { render :xml => @project }
    end
  end

Thanks again

Re: has_many and belong_to association not working

Thanks again Roy.  After I put it in the new action it looked like
this  and i left off the xml stuff but it still didn''t pass the
call.id to the
call_id field in the visit.  I can''t figure out why - maybe its the
link_to ''New Visit '' line in my show view in my calls.views I
don''t
know.


  def new
    @visit = Visit.new
    @visit.call_id = params[:call_id]
  end

Re: has_many and belong_to association not working

Hmmm--so either we''re not getting a value in params[:call_id] or
it''s
not making it into the visits/new form.  Probably the former.

I''m sure there''s a better way to echo the contents of params
to the
browser from a controller action (little help anyone?) but for now, can
you make this the first line in VisitsController.new:

  raise(debug(params))

And let''s see what''s in that params hash...

Thanks again Roy.  After I put it in the new action it looked like this
and i left off the xml stuff but it still didn''t pass the call.id to
the
call_id field in the visit.  I can''t figure out why - maybe its the
link_to ''New Visit '' line in my show view in my calls.views I
don''t
know.


  def new
    @visit = Visit.new
    @visit.call_id = params[:call_id]
  end

Re: has_many and belong_to association not working

Hello Roy

I got an NoMethodsError in VisitsController#New and undefined method
''debug'' for for #<VisitsController:0x19b90c8>


What I put was

class VisitsController < ApplicationController

  def index
  end

  def show
    @visit = Visit.find(params[:id])
  end

  def new
    raise(debug(params))
    @visit = Visit.new
    #@visit.call_id = params[:call_id]
  end


  def create
    @visit = Visit.new(params[:visit])
    if @visit.save
      flash[:notice] = "Visit submission succeded"
      render :action => ''show''
    else
      render :action => ''new''
    end
  end

end

And then at the bottom of all the errot stuff I got So I''m not sure if
this is what you want but it does say call_id is 43
which is correct.

Request

Parameters:

{"call_id"=>"43"}

Show session dump

Re: has_many and belong_to association not working

Hello again Roy
I was wondering - does it make any difference that I use
render :action => ''show''
rather than redirect_to :action => ''show'' in the def create
action?
Thanks again and again

Re: has_many and belong_to association not working

I suspect it doesn''t matter, but am not sure.  The scaffold-generated
code (for version 2.0.2, which is what I''m using) does a redirect_to,
but I don''t know what informs that choice.

Hello again Roy
I was wondering - does it make any difference that I use render :action
=> ''show''
rather than redirect_to :action => ''show'' in the def create
action?
Thanks again and again

Re: has_many and belong_to association not working

Ach--okay.  I didn''t realize debug wasn''t available in a
controller--sorry about that.  But no matter--rails'' stock error
handling echoed the params anyway--I think we know now that your link_to
call is successfully moving the call_id.  So now we look at the next
step in the chain--your visits/new view.  You''ve got to include the
call_id attribute somewhere in your form, so that when it gets posted
back to the server, it (again) gets stuffed into the params[], so your
VisitsController.create method can stuff it into the database.

Looking at the view code you posted earlier in the thread, I''m not
seeing a reference to the call_id.  So--within your form_for ... end
block throw in a:

  <%= f.text_field :call_id %>

That will actually show the call_id attribute--verify that it''s getting
the value you want.  If that fixes your problem (and I suspect it will)
then you can change that to

  <%= f.hidden_field :call_id %>

And then it won''t be shown to the user, but it will still be part of
the
form.

Hello Roy

I got an NoMethodsError in VisitsController#New and undefined method
''debug'' for for #<VisitsController:0x19b90c8>


What I put was

class VisitsController < ApplicationController

  def index
  end

  def show
    @visit = Visit.find(params[:id])
  end

  def new
    raise(debug(params))
    @visit = Visit.new
    #@visit.call_id = params[:call_id]
  end


  def create
    @visit = Visit.new(params[:visit])
    if @visit.save
      flash[:notice] = "Visit submission succeded"
      render :action => ''show''
    else
      render :action => ''new''
    end
  end

end

And then at the bottom of all the errot stuff I got So I''m not sure if
this is what you want but it does say call_id is 43 which is correct.

Request

Parameters:

{"call_id"=>"43"}
