But your code is otherwise so messed up that I can't tell exactly what you're 
trying to do. What is the "do" at then end of the call to link_to? Is the 
<%end%> after  intended to be associated with it? Or is it supposed to 
be for the @defautrec.each, but is just in the wrong place?

I suspect you're trying to wrap a button in a link, but that's not how HTML 
works, regardless of whether you're using Rails or not. Do you just want a 
button that acts like a link??? It that's the case, you want button_to:




Anyway, you cannot just stick "do" at the end of a function call in order to 
start a loop. Remember, <%= %> just executes the Ruby code inside and inserts 
the result into the HTML, and this is not legitimate Ruby:

link_to controller: "pages", action: "ajouter" do

Or, for more clarity, since this is the way it would be parsed:

link_to (controller: "pages", action: "ajouter" do)

If you are dynamically generating the table, then you know what index each row 
of that table is, don't you? And if you are generating the table using a 
collection of data, then you know the :id (for example, or the color or stock 
number or any of the parameters of the underlying object) of each item as you 
draw the table. Adding that value to the link_to generated code is a trivial 
exercise.

for foo in @foos

foo.bar
foo.baz
link_to foo.boo, foo.blarg, :stock_number => foo.id

end

Does that help? (Left off all the erb stuff 'cause it's early.)

<%= @operation.id %>

You use @operations.each, just like any other variable. It doesn't matter 
whether it's a model or not.

Fab,
You seem to have put several concepts into one description of the "problem".

Perhaps if you break it into its parts like:

* The link/button initiates a request back to the server
  ( link_to("Text", my_view_path(article), remote: true) )

* The config/routes.rb specifies how a request is directed to a particular 
controller/action

* The action can use the params from the request to determine what to render or 
where to redirect.

Does that help you either understand the problem or at least indicate which 
part you really have a question about?

You can, but you may need to do it a different way.  The first
question is whether you need to use a form, do you need to post data,
or is each button effectively just a link?

[Rails] Use table elements

[Fab Forestier]

Sorry th etitle of the topic isn't very clear but it's difficult to
summarize my problem!

I made a view without model but I display in table the content of a
variable named '@operations'. So each line corresponds to an operation.
In my table I have also a column with a button for each line. When i
click on the button I want to redirect to an existing page 'Operation'
witch correspond to the operation of the line of the table like in the
index view with the 'edit' or 'delete' button.

But I can't do the same think because I'm not working with a special
model in this view.

Is someone did somethink like this yet?

Fab
