Determine if app uses prototype js? - ruby-on-rails

Im taking over an app that was started by someone else. I want to use jquery, but from what i read, the only way to use it replaces Prototype. This shouldnt be a problem, but im not sure if the project uses any protoype. Is there a plugin i can run or something that searches the project and checks compatibility without prototype?

I am not aware of any. The only way I can think of doing it would be to make the change and hunt for errors then translate them to JQuery. Most are not hard. They are usually just slight differences like addClass instead of addClassName

You can use both prototype and jquery, using jquery's NoConflict mode. You can also look at the jquery-rails plugin that removes prototype and reimplements the helpers using jquery.

How do I turn a RoR view to Responsive (html5)

I have a normal view in html in Rails, containing images and links. How do I turn it to be responsive? (I want it to fit also mobile browser sizes, make it html5)
I know I should use fluid, but what is the full command? Or is there another/better way directly from the text editor?
Rails has limited control on the HTML that comes on to the browse.
Try looking at frameworks like Bootstrap or Foundation.
There are some gems that can help you
Foundation-rails
twitter-bootstrap-rails
There is also a railscast episode on Bootstrap basics.
This has nothing much to do with Rails. Rails is a server side language and responsive templates are frontend (html/css) dependent.
However if you are specifically using bootstrap as many beginners do, you could try : https://github.com/seyhunak/twitter-bootstrap-rails gem for a quick integration of things.

Can an admin template be used in a Ruby on Rails web app?

I have been doing UI research and have come across admin templates at http://themeforest.net/. I was wondering how do you apply these onto a web app built on Rails. These templates look very similar to wordpress themes. Are they that easy to configure? Is it just as simple as setting up a link to the database to make the fields form capture data? I've been looking at this theme.
For admin templates I recommend using Active Admin. It's relatively easy to implement and gives you great admin screens with little effort.
Yes, You can. I'm trying to solve the same problem and so far I have a couple options:
1.) do it by hand, I've done this before, it works but takes a lot of time to truly understand how your theme is put together. First I would recommend using the included themes assets exactly as they are bundled with the theme. Don't assume that just because you have twitter-bootstrap-rails gem that the bootstrap classes in the theme will work. Link the assets statically and slowly extract out the static assets and replace them in the asset pipeline once you know they work.
2.) Use the strategy suggested in the install_theme gem (http://drnicwilliams.com/2009/10/06/install-any-html-themetemplate-into-your-rails-app/) the gem itself is not maintained any longer (i'm not sure about any forks), but the strategy is sound. Extract the core parts of the template into partials.
The short answer is yes, but there is no straight forward way to "import to rails"

ruby on rails 3.1 web design

May I ask you how to make rails web design more efficient?
Is compass plus blueprint the perfect match?
Is the current version of compass support rails3.1
Are there any other frameworks that will make rails web deign easier?
Thanks
Definitely a framework like compass is awesome, it includes a lot of helpers, and provides a good solid base.
For form-styling I would recommend using a gem like [formtastic][1], which not only greatly simplifies making forms, but also provides a standard css file. So all needed tags are then known (and can be overwritten if needed).
There a few alternatives to kickstart your application's layout:
twitter-bootstrap: it is plainly awesome and provides a great start (it does not play nice with formtastic, but works perfectly well with simple_form).
web-app-theme provides generators, and a set of templates to style your application quickly
activo is a template that is contained in web-app-theme, but can also be used standalone
Hope this helps.

Which JavaScript framework would be better to be used for Rails?

I have been using jQuery for all my projects in PHP, Java etc. but now since I am starting up with Rails, I am bit confused about whether to stick with jQuery or use Prototype. Since Rails by default supports Prototype, is there any added advantage in using Prototype? Would it be fine if I use jQuery? Which JavaScript framework do you guys normally use?
jQuery will now be the default javascript framework in new version of rails. jQuery is best without any doubt.
Prototype came first but jQuery won the JavaScript framework wars. Rails 3 ships with jQuery by default, not Prototype. Use jQuery—it's pretty much the industry standard now.
Rails 3 is framework agnostic, just use whatever you prefer. I use Jquery.

How to create picture slideshows in a rails project? Flash or otherwise

In a rails project how would I create a picture slideshow? It could be generated as flash or use prototype or something else.
I just want a series of images (as a sub-part of a web page, not be the whole page) to fade into each other, and to advance manually if clicked. It would be nice if I could do things like slowly zoom into the images
I imagine there must be a plugin or something to handle this?
Since this is a UI feature, I'd just use the JQuery plugin CycleLite. See this article from Eric Berry on O'Reilly Ruby or, for a Rails solution, this extract from Ruby on Rails: Up and Running.
