Rendering another model's views

Rails
#1

I want to render Model B’s views inside Model A’s, how would I do this?

For instance, I want to display the “new.html.erb” of Model B in A’s
index.html.erb, and be able to create new B’s in A.

Thanks.

Views correspond to controllers, not models. If that is what you mean,
in
Controller A, you can redirect_to B, use render :controller => :B,
:action
=> :new, or just move new.html.erb into A’s views. Unless you are also
using it for B alone, this makes more sense

Another option is to move the content of the view into a partial and
have each parent render the partials. So you’d have something similar to

controller A

def new
…
end

views/A/new.html.erb

render :partial => ‘/’

controller B

def new
…
end

views/B/new.html.erb

render :partial => ‘/’

If the partial you are rendering is a form, you can set instance
variables containing the controller and action to post to. I’m doing
something similar to this right now in that I have a particular form
that I am using in three different situations.

Are you getting some kind of error? Post all relevant code so we can
have a look.

In which file is a dom element with the id ‘results’ defined? Is it in
the current page at the time of the ajax request?

The ‘results’

is in index.html.erb

No error. When I click the link, it just seems as though nothing is
happening.

\views\users_user_management.html.erb:
<%= link_to_remote( “Add requirement”, :url => { :action =>
:show_add_req } ) %>

\controllers\users_controller.rb:
def show_add_req
if(request.xhr?)
render :update do |rjs|
rjs.replace_html :results, :partial => ‘\req_details\form’ #
tried multiple things here ‘form’, ‘_form’, ‘\req_details\form’,
‘\req_details_form’,…
rjs.visual_effect(:blind_down, “results”, :duration => 1)
end
else
redirect_to_index and return
end
end

\views\req_details_form.html.erb:
sdfkjsdlfkjsdlfkjsldkfjsdkf

That’s all of the relevant code…I think.

Thanks for the help!

Okay. Let me make sure I understand. You hit the index action which
ultimately renders the partial \views\users_user_management.html.erb.
That partial includes the link_to_remote which calls the show_add_req
action. That action updates the results div which is part of the
index.html.erb view. So the only thing we haven’t seen yet are the
contents of req_details/_form. I’m wondering if you’re missing an
instance variable or something in the show_add_req action.

\views\req_details_form.html.erb:
sdfkjsdlfkjsdlfkjsldkfjsdkf

I just stuck that in for testing purposes…

I think the problem must be in the action show_add_req
def show_add_req
if(request.xhr?)
render :update do |rjs|
rjs.replace_html :results, :partial => ‘\req_details_form’
rjs.visual_effect(:blind_down, “results”, :duration => 1)
end
else
redirect_to_index and return
end
end

Particularly, rjs.replace_html :results (<-/users/views/index.html.erb),
:partial => ?? (<-req_details/views/_form.html.erb)

Thanks

The ‘results’

is in index.html.erb

Hi Justin,

I think I might have an idea. Comment out the visual_effect line and try
again. I believe you’re getting an error in the javascript, and you’re
just not seeing it. Are you using Firebug? You would be able to see it
in there. I think your visual_effect line is incorrect at the duration.
It should have the duration in curly braces as a hash, like

rjs.visual_effect(:blind_down, ‘results’, {:duration => 1})

At least that’s how I have always coded it. Maybe I’m wrong. It’s worth
a shot, though.

Peace,
Phillip

I remember you from my filemaker days.

Heavily suggest that you learn rails with sql db first so that you get
the power of rails before you attempt to connect to a Filemaker DB
because that’s likely to be disappointing (wouldn’t know, I never
tried).

Once I got into Rails, Filemaker seemed so painful and I have stopped
doing Filemaker.

\views\users_user_management.html.erb:
<%= link_to_remote( “Add requirement”, :url => { :action =>
:show_add_req } ) %>

Let me try to understand , you said u have parent and child models/
views.
and u wish to call daughter action from parent view.

try adding controller => "daughter " to the link_to_remote url

I’m out of my league here for sure, but shouldn’t that partial reference
be:

:partial => ‘req_details/form’

instead of:

:partial => ‘\req_details_form’

?
