I generated a simple controller using “script/generate controller form
myfun”.Then edited a /app/view/form/myfun.html.erb simply as
Hello
<%=link_to 'Submit'%>
I created a another
controller using “script/generate controller click fun”.Edited the app/
view/click/fun.html.erb to hold a welcome message as
Welcome
I want click on
submit should show this message,but dont know how to connect these two
controllers.using rails .I am using rails 3.0.7.
Please somebody guide me
Thanks

It is important to distinguish between the three components Model View
Controller of MVC design. If you are not clear on these then some
googling and reading might be worthwhile. I presume that what you
actually want to do is link to a controller action from the view of
another controller. To do that simply put use link_to to link to the
the controller/action that you want.
I think I suggested in a reply to one of your earlier questions (if it
was you, apologies if not) that you worked right through some
tutorials, the free to use online one at railstutorial.org is very
good. Once you have done that then these very basic questions that
you are asking will not need to be asked.

I add the link to click controller(it has a fun action)
You are confusing controller and view again, you cannot add a link to
a controller, only to a view.
as ,but i gave error(may be a syntax error in specifying a controller
path).
Hello
<%=link_to 'Submit',click_path%>
That should probably be clicks_path (plural). If you run
rake routes
it will show you the routes you have defined, one of which will be
something like
clicks GET /clicks(.:format) {:controller=>“clicks”,
:action=>“index”}
which will tell you that clicks_path is a valid route.

So why did you not say last time that the clicks routes are not there?
If you have not got the routes setup then the _path variables will
not be defined. I suggest you read the Rails Guide on Routing.

This means that the URL helpers that exist are click_fun_path,
home_index_path and root_path.
You can use clicks_path because it doesn’t exist.

It was path syntax error.Now i used
"<%=link_to 'Submit',click_fun_path %>" and it worked.
please tell me one thing ,click_fun_path is path to click
controller or click view??
Thanks to colin and Frederick C…

As I suggested previously it would be worth your while reading up on
MVC architecture, as it is fundamental to Rails apps. There is no
such thing as a link to a view, links are always to controller
actions. Also as pointed out previously you can see that from the
output of rake routes that you posted:
click_fun GET /click/fun(.:format) {:action=>“fun”,
:controller=>“click”}
That says that click_fun_path is a route with url click/fun (with
optional format) which will run controller click, action fun.
