I'm using the gems "haml" and "haml-rails" in my rails app and I have this folder structure
-views
-layouts
-public
-layout.html.haml
-_header.html.haml
-_footer.html.haml
And i wanto to render _header and _footer in layout.html.haml using this code:
= render 'layouts/public/_header'
.container= yield
= render 'layouts/public/_footer'
but rails raises a MissingTemplate error but _header and _footer exists...
how can i solve?
You typically omit the underscores when specifying partial names in these helpers. Also, you should be passing them in as a :partial parameter:.
= render :partial => 'layouts/public/header'
.container= yield
= render :partial => 'layouts/public/footer'
partials are named with a leading underscore to distinguish them from
regular views, even though they are referred to without the
underscore.

I have a problem. I need to render objects using partials of another namespace.
render complain.target
it tryes to render partial from current namespace(current is admin)
Missing partial admin/bulletins/bulletin...
I dont need to render it from admin/..
I cant specify partial path like
render partial: '/bulletins/bulletin', locals: { bulletin: complain.target }
But it's polymorphic association, and different partial pathes are used.
Is it any way to do it?
Thanks in advance!
There seems to be no possible way to achieve this with a render complain.target call (Checked on Rails 5 source).
There is a config option for action_view to disable namespace prepending for partials, though:
Rails.application.config.action_view.prefix_partial_path_with_controller_namespace = false
EDIT
Today, I've used another solution:
When rendering Single-Table-Inheritance models into partials, one can pass the locals variable name based on the Rails model_name lookup, when calling the render partial:
<%= render partial: "admin/#{object.to_partial_path}",
locals: { object.model_name.element => object }
%>
You can use render "/#{complain.target.to_partial_path}"
I've come across an oddity that I can't quite explain with regards to Rails 3 and rendering partials with layouts (from the controller). I'm hoping someone can provide a little insight into what's happening.
First off, we'll call this controller a "legacy" controller. It's been around for a long time and is doing a lot of things wrong, but I'm not looking to refactor it at this point so I'm trying to find ways to work with what we have.
The new action is something like this (in the BarsController)
def new
if something
render :partial => "foo", :layout => "bars"
elsif something_else
render :partial => "foo2", :layout => "bars"
elsif something_else_else
render :partial => "foo3", :layout => "bars"
else
render :partial => "foo4", :layout => "bars"
end
Now, in Rails 2.3.5, this worked fine. It would render the appropriate partial inside the appropriate layout -- I realize the layout option is redundant here as it would default to the bars layout regardless. When we upgraded to Rails 3.0.x, we started getting errors as follows:
Missing partial layouts/bars with {:handlers=>[:erb, :rjs, :builder, :rhtml, :rxml], :formats=>[:html]
Clearly the layouts/bars.html.erb file is and always has been there, so I couldn't figure it out. I was able to render with :layout => false, but that of course wasn't going to work. Eventually I figured out that if I do either of the following, it works:
1) Rename my layout to _bars.html.erb instead of bars.html.erb and:
render :partial => 'foo2', :layout => 'bars'
2) Keep my layout as bars.html.erb (what I want) and :
render '_foo2' # :partial option is redundant here anyway
It seems as though by using the :partial option instead of the string as first parameter is causing rails to apply the _name.html.erb convention to both the partial AND the layout. If I put in the underscore on my own, it falls back to the behaviour I expected which is to not prepend an _ infront of the name of the layout.
Does anyone know why this is the case?
EDIT Alright, not sure how I missed this... but here's something in the docs making mention of this. It seems as though it's been around since 2.3.8, perhaps it was done differently in 2.3.5 (what we were running on)?
3.4.3 Partial Layouts
A partial can use its own layout file, just as a view can use a
layout. For example, you might call a partial like this:
<%= render "link_area", :layout => "graybar" %> This would look for a
partial named _link_area.html.erb and render it using the layout
_graybar.html.erb. Note that layouts for partials follow the same
leading-underscore naming as regular partials, and are placed in the
same folder with the partial that they belong to (not in the master
layouts folder).
Here's my own answer to the question based on what I've edited above:
Since Rails 2.3.8, it would appear as though the default behaviour when rendering a partial with render :partial => 'foo', :layout => 'bars' is to expect a "partial layout" file as well as a partial view file. In this case it will expect
app/views/_foo.html.erb as well as app/views/layouts/_bars.html.erb
For anyone encountering this problem upgrading from Rails 2.3.5, here's the solution I found to have the least amount of impact:
render '_foo', :layout => 'bars'
This solution does not assume you're rendering a partial and therefore does not expect a partial layout. The other option would be to duplicate your layout to
app/views/layouts/_bars.html.erb
and using
render :partial => 'foo', :layouts => 'bars'
but that results in some duplication of code.

I am developing a rails 3 app for 2 locales (:en, :kr).
I have 2 view files:
index.en.html.haml
index.kr.html.haml
And each file uses partial.
_info.en.html.erb
_info.kr.html.erb
(Partials are erb instead of haml)
= render :partial => "info"
This always uses _info.en.html.erb ignoring locale.
Partial can't be auto-selected for locales?
Thanks.
Try
= render :partial => "info"
I have a file in:
RAILS_ROOT/public/system/pages
It is a snippet of HTML. I would like to render it, along with other things, in one of my views.
But it seems like when I try to do a render from a view, Rails is always looking for a partial. But it doesn't pick up the file even when I name it with a leading underscore. How can I read and display this HTML snippet within a view?
have you tried with
<%= render :file => 'your/path/', :layout => false %>
inside the erb?
I am migrating my 1.8.7 rails app to rails 3. But I have a problem with a partial:
I have the following partial:
in my cms controller :
#clients = Client.all
group = render_to_string :layout => 'layouts/window', :partial => 'clients/index'
in my "clients/index" partial:
<%= render :partial => 'clients/item', :collection => #clients %>
This worked great with rails 1.7.8 but with rails 3 only the partial in the index get's rendered!. So, to clarify this, the group variable in the controller doesn't get the html from the layout.
Also the weird thing is that the window layout is _window.erb (if I do window.html.erb or just window.erb rails can't find it which is strange).
Does anybody know if this behavior is normal for rails 3?
thanxs!
Partials in rails have to start with underscore. Try renaming your "item.html.erb" partial to "_item.html.erb".
