Render a partial on buttonclick?

Rails
1

I currently have a link to a Login screen, but its a separate page
althogether. I have created a partial that is just the login box and
password, and would like that partial to appear at a place on the page
when the user clicks the link. Anyone know where I can find out how to
do this?

Thanks so much.

You use link_to_remote instead of link_to… then you have the
destination
be a controller that just renders your partial and puts the result in
that
div. Pretty easy actually.

<%= link_to_remote “Delete this post”, :update => “login_form”,
:url => { :action => “show_login_form”, :controller=>“login” } %>

Then in your controller, assuming you have a partial at
app/views//login/_form.rhtml you just do

displays the login form partial… used by an AJAX request

def show_login_form
render :partial=>“login/form”
end

You can do a lot more cool stuff though… There’s a really good O’Reilly
shortcut on RJS, but sadly I forget what it’s called… I think it’s RJS
Templates for Rails or something. Quality read, and helps you get
started
quite quickly.

it works out…
Thanks so much!

Ok so some of it worked, but not all of it. I have the partial “app/
views/login/_login_small.rhtml” that has this:

=========================================================
<% form_tag do %>








username:
<%= text_field_tag :name, params[:name] %>
password:
<%= password_field_tag :password, params[:password] %>
<%= submit_tag “Login” %>

<% end %>

and my layout which should be the header for every page, "app/views/
layouts/application.rhtml

=========================================================
<%= link_to_remote “Login”, :update => “loginPartial”, :url =>
{:action => ‘show_small_login’, :controller => ‘login’} %>

=========================================================

and the problem is that it is rendering the main “login/index.rhtml”
instead of my partial… any idea why?

Use a link_to_remote for the link. In the action it calls,

render :page do
page[:id_of_place_on_page].replace(:partial => ‘path_to_partial’)
end

don’t forget to setup the variables used in the partial in the action
as well.

What’s your controller’s action look like that does the rendering?

Couldn’t you also do this in your controller?

displays the login form partial… used by an AJAX request

def show_login_form
render :partial=>“login/form”, :layout => false
end

So it wouldn’t render the layout for that action?

Here is my action:

def show_login_partial
render :update do |page|
page.visual_effect :fade, ‘loginPartial’
end
end

Here is the location of the actual link on the rhtml page:

<%= link_to_remote “Login”, :update => “loginPartial”, :url =>
{:action => ‘show_small_login’, :controller => ‘login’} %>

I’m looking for the same effect as http://www.digg.com when you click
login…

You can look at the source code of Digg.

They have a division where they keep hidden and when you click on it
they just show it.
