I new to Ruby on Rails, and I am coming from Drupal/PHP background.
I am trying to do something simple. A "Static" controller for some pages like about us, disclaimer etc. and a "Video" controller for videos.
The whole application has same look. I am trying to figure out how I can avoid duplicating views.
In drupal the theming goes like this:
html.tpl.php (renders page.tpl.php)
- page.tpl.php (renders multiple block.tpl.php)
- block.tpl.php (renders more nested tpls or some html generated by theme functions).
I find this to be great.
In rails, what I read is there is application.html.erb (Which I think is similar to html.tpl.php of Drupal, as it normally contains stylesheets, js, etc. available throughout the application) called "Layout". Then there are "Views", which "yield" content in this layout. We specify the view in controller, or it gets one automatically. I think of a view as "page.tpl.php" of Drupal.
Most of my site uses same structure i.e. header, top menu, content, right sidebar, footer. But content of each area changes depending on the path. So I am thinking of doing it like this:
Both 'Static' & 'Video' will call the same view, with different variable values i.e. values for content area and sidebar.
This View will the use 'render' to render another view, with a subset of variables passed from controller i.e. it will render content & sidebar views.
If needed, those views will render more views, and so on.
Another one I read about is partials. I can't seem to differentiate between rendering a view inside another view, and rendering a partial.
Which method is better? Or is there a better "Rails Way"?
This is quite a large topic to cover but edited highlights are
If you want to repeat content on every page, like a header or navbar for example then put it in layouts/application.html.erb
if you want to keep your views tidy with content specific to that page then you can use partials. Normally in views I create a folder called shared and then put my partials in there. for example if i save a partial called _form.html.erb (make sure you name partials with the underscore at the beginning of the file name), i would then call that in my view like
<%= render 'shared/form' %>
you can also use partials in the layouts/application file to keep that clean aswell
This is just my way of doing it, I'm sure more experienced rails guys have better ways
Hope that helps, any more questions then just ask

I would like to share content (essentially blocks of html) between templates.
For example, suppose I have a common footer section with a graphic or two, text and links to 'about us', 'contact us' and so on.
I have different templates for different page layouts, but they all require this footer.
So far I can think of three ways :
Nesting templates : ie have a master one which has the footer content, then a child one for each layout, then the actual page template, but this could get tricky if some pages need a different footer
Using a Partial View to hold the footer content and using #Html.Partial() to pull in the partial view on the various templates
Create a settings document with the footer content and use Umbraco.Content() to fetch the footer property
Is any of these the recommended process (and are there any pitfalls?) or is there a better way?
I would normally do one of the following:
Have properties on the homepage for the footer links etc (in a separate tab) and pull in the values into the footer partial, this way you only have to set it once, rather than having it on every page
Have a Site Settings node at the same level as the home page and pull the values from there into the footer partial
That seems to be fairly standard from most of the Umbraco sites that I've worked on. I wouldn't have all of the properties on each page, unless you need a unique footer each page for some reason.
For example, lets say you add a tab called "Footer Settings" to the Home Page DocType with a single string property with the alias "copyRightNotice" and then you want to display that in a partial, your partial might look something like:
#inherits Umbraco.Web.Mvc.UmbracoTemplatePage
#{
var rootPage = Model.Content.AncestorOrSelf(1);
<h3>#rootPage.GetPropertyValue("copyRightNotice")</h3>
}
With Grails, is it possible to get the name of the view that is being rendered while in the layout GSP file? I'd like to change one minor thing in the layout file depending on which view is going to be rendered.
If found this to be rather difficult to determine. It's easy if you use conventions, but you can always explicitly render any view you want. See the code in How to detect which view file has been rendered in grails for how to determine this in a filter.
The name of the view is normally the same as the action that has just been executed (e.g. show action normally renders the show.gsp view) - if this is the case in your view, then you can get it in your layout gsp using ${actionName}.
I am busy changing the default T4 Templates that gets generated when I click on the "Add View" dialog from my Controller. I know how to change the templates. But the following i can not wrap my head around.
I want to be able to generate the following when the user clicks on Add View.
A partial view that only contains the Form part of the view that is generated by default
A View that calls the partial view generated above.
Is it possible to generate 2 files like this using the T4 Templates ?
thanks in advance
Why? Are you going to be routinely doing this exact same thing over and over again? If so, then a T4 template may make sense. If you're doing it once or twice, then just modify the files by hand.
I am looking for a way in Ruby on Rails to render a completely different controller's action within other views.
For example I am writing a band website that displays their albums. So I have /albums/list that shows a list of all of their albums with other stuff around the page as the layout. Now what I am looking to do is also render /news/list in every page as part of the layout as well so that every page you go to you can see it.
I cannot find a way to call the news controller list action and display it in the list view using partial views. Any help would be appreciated.

render() method give you ability to render specific file, placed in any directory :)

I am working on a help page which is composed of a navigation tree, content box, and search box. The navigation tree has links to Frequently Asked Questions and Glossary, each of which are linked to an Action which return partial views.
To the right of the navigation tree I have a single content div that I would like to contain whichever partial view is selected in the navigation tree.
Success case (what I want to accomplish): clicking on one of the FAQ links calls the FAQ() method in my controller, then returns a partial view which is then displayed in my content div to the right of the navigation tree. Clicking on another item would cause another partial view to be loaded.
How do I go about this? I've read a ton of ASP.NET MVC JQuery loading blog posts and tutorials but can't find anyone who's done exactly this.
Many thanks!
You should be able to use the jQuery method .load() to load HTML into your div.
http://api.jquery.com/load/
You can create an action that returns the partial view as HTML.
ASP.NET MVC Returning Partial View as a full View Page
jQuery:
one easy way you can do is load all partial views in "Container Div" at page load in one go (if performance is not a issue)
then assign each partial div with different div id inside "container", than use jquery to control show(); hide(); for each div.
MVC:
however if i were you, "Glossary" and "FAQ" looks same model to me it shouldn't be put in different partial view in first place.
if they did designed in separate model, in this scenario, i would recommend you to create a proxy class as a ViewModel above models you want to display, and then load it with one partial view only
