Output link_remote_to in helper

Rails
1

Hi all,

I have a complex link_remote_to link I need to generate often. I want
to DRY up my view and create a helper that generates this
link_remote_to for me.

Is there a way my helper can output the link_remote_to javascript?

Thanks
STijn

I haven’t actually tried this, but I’m thinking it should work. Since
link_to_remote is just a helper, I don’t see why you couldn’t create
a helper that calls it. Something like:

def my_link_to_remote()
link_to_remote
end

It wouldn’t be hard to find out.

nope, tried that but that doesn’t work.

I’ll have to put it in a partial I think.

It always just outputs 1 linkto_remote (the second). I’m I doing
something wrong?

You are experiencing one of the niceties of Ruby: the last “thing” in
a method gets returned.

You will want to capture the output of both calls to link_to_remote
and return them together. I have not tried this, but somethiing
like this should work

link_string = ‘’

link_string = link_to_remote blahblahblah
link_string += <something to separate the links, maybe a
?>
link_string += link_to_remote blahblahblah

return link_to_string

You might want to do some more research then. I just did a simple
test like this:

In a view template

<%= my_link_to_remote ‘Click here’, ‘wgg’, ‘link_to_test’,
‘link_to_target’ %>

in the helper

def my_link_to_remote(label, controller, action, update)
link_to_remote label, :url => {:controller => controller, :action =>
action}, :update => update
end

and in the controller

def link_to_test
if request.xhr?
render :text => Time.now.to_s
end
end

And it worked as I expected it to. You should be able to pass in
whatever args you need and call link_to_remote to build the link for
you. Unless your need is extremely complex. Maybe you can post some
example of what you’re trying to do?

Peace,

I got it to work. The link_to_remote indeed just works in the helper.

I have an additional problem though:
I want to output 2 link_to_remotes to my view with the helper:

I have something like
if(condition1)
link_to_remote1
link_to_remote2
else
link_to_remote1
link_to_remote2
end

It always just outputs 1 linkto_remote (the second). I’m I doing
something wrong?
