partials in layouts ?

Hi Gurus, how do I include a partial in my main layout?

In views/layouts/application.html.erb I have

<code> ... <%= render :partial => 'navbar_tabs' %> ... </code> No matter where I put _navbar_tabs.html.erb (or renamed it to _navbar_tabs.erb in desperation) I get the error

Showing app/views/layouts/application.html.erb where line #20 raised:

Missing template messages/_navbar_tabs.erb in view path app/views

Can you help?

TIA, Craig

Try giving the whole path in render like this:

<%= render :partial => ‘/messages/navbar_tabs’ %> # if your partial is in messages directory.

Let us know if this does not work.

Thanks--

<%= render :partial => 'layouts/navbar_tabs' %>

works. Seems kind of ugly, though--even in layouts, shouldn't a form look in its own directory for a partial?

Anyway, thanks!

Seems surprising to me as well.

Thanks, Abhinav

What happens if you name it _navbar_tabs.html.erb and put in in views/messages?

Thanks–

<%= render :partial => ‘layouts/navbar_tabs’ %>

works. Seems kind of ugly, though–even in layouts, shouldn’t a form

look in its own directory for a partial?

If you’re using the partial in the layout, it means the partial will be displayed

on every page of the site by default. Is this the case?

By convention, any partials that are loaded by "application.html.erb" are loaded by all controllers in the application. That being the case, when rendering app->messages->index:

  The app...erb line will read "<%= render :partial => 'layouts/ app_wide_partial' %>   The partial will be found in views/layouts/ _app_wide_partial.html.erb   When the line in app...erb is reached that reads "<%= yield %>"      The file "views/messages/index.html.erb" is rendered

  And you have a file views/layouts/application.html.erb     that calls "<%= render :partial => 'navbar_tabs' %>"   Rails will look for the partial named: views/messages/ _navbar_tabs.html.erb

It is customary practice to follow the convention "... :partial => 'directory/partial' %>" just so there is no confusion. Thus, if you had additional message related tabs, you would include in views/ messages/index.html.erb: <%= render :partial => 'messages/ msg_navbar_tabs' %>

It does, you're just misunderstanding what "its own directory" refers to. Your form is not a part of "layouts," it's a part of the controller rendering it.
