Generate link_to without path (only anchor) - ruby-on-rails

I need to have path like "#privacy" for tab plugin. Link must contain only anchor. When I use link_to 'Privacy', :anchor => 'privacy' Rails generate /privacy#privacy - link, that contains full path and anchor.
How can I told Rails to generate url without path (only anchor)?
Thanks.
Solved: link_to 'Privacy', '#privacy'

The following will create a link the way you want -
link_to "my-privacy", "#privacy"
In most browsers, the path of the current page will be prefixed, but if you check the source of the page, the following html will be seen -
my-privacy
This will most probably serve your purpose for the UI, just that you'll have to split the url at '#' using Javascript.

This will work for you
<%= link_to "title", resource_path(:anchor => "anchor") %>

No generation of routes is needed also no generator is needed.
<%= link_to "link text", "#", :id => 'your_id_here' %>
You will need the id to access the object via jQuery.
//edit
<%= link_to "link text", "/#anchor", :id => 'your_id_here' %>

Your best bet for this exact scenario is to just use <%= link_to "link text", "#anchor" %>. The anchor tag is used within url_for and doesn't really give you a clean way to just use an anchor.

Form_tag link to page in another folder

I am integrating 2 rails projects using button to link the first project to the second. Now I have this code
<%= form_tag fast_url_for(' ') do %>
<%= button_to AppConfig.app_clockout %>
<% end %>
and my current directory is
/var/www/html/wizTime/wizProject/Source/project_1
but I don't know how can this redirect to the home page of another project. The directory of my second project that I want to integrate is
/var/www/html/project_2
Please give me ideas. Thank you!
If you only want a link_to and your projects will have domains later, you can just create a link like this in rails:
<%= link_to 'sec project', "http://www.rubyonrails.org/" %> which will create an ordinary html link: <a href=""http://www.rubyonrails.org/" ...>
The form usually should not link to another project?!
If after submitting the form you want to redirect the view to another project, than you can use the controller action and redirect after submit.
As the other commenter said - you can just create a link to the other domain. You should not ever rely on your directory-structure - because when you deploy, that directory structure will very likely be subtly different.
So use the domains instead.
You can even put the domains into environment variables so that you can use different domains (eg localhost:3000 vs localhost:3001) on your development machine. you'd use them like this:
<%= link_to 'My App', ENV['MY_APP_DOMAIN'] %>
<%= link_to 'My Other App', ENV['MY_OTHER_APP_DOMAIN'] %>
Then google for how to set environment variables on your local machine to set the values.
If you want them to be buttons... then you don't need to use a form. button_to creates its own form and is used exactly the same way as a link_to eg:
<%= button_to 'My App', ENV['MY_APP_DOMAIN'] %>
<%= button_to 'My Other App', ENV['MY_OTHER_APP_DOMAIN'] %>
However... you really don't need to use a button-to if you are just doing a GET for a URL like this...
(you use buttons when you need to POST data eg POSTing form data to a create action)
You can just pass in a CSS-class and style the link-to to look as though it were a button.
eg using Bootstrap classes:
<%= link_to 'My App', ENV['MY_APP_DOMAIN'], class: 'btn btn-success' %>
<%= link_to 'My Other App', ENV['MY_OTHER_APP_DOMAIN'], class: 'btn btn-danger' %>
OR similar.

Ruby on rails submit button

am new in ruby on rails and please i want to execute a method in my controller or in my helper when i click this button, so any ideas for that?
<%= button_to 'Export POINT', :action => :create_file_txt %>
Thanks
Route
button_to is basically a link:
Generates a form containing a single button that submits to the URL
created by the set of options. This is the safest method to ensure
links that cause changes to your data are not triggered by search bots
or accelerators. If the HTML button does not work with your layout,
you can also consider using the link_to method with the :method
modifier as described in the link_to documentation
You need to send it to a route:
#config/routes.rb
get "your_route", to: "controller#action"
This will give you the ability to use the URL helpers to define the path & get the button to work:
<%= button_to 'Export POINT', your_route_path %>
Link
As per the comments, you would also benefit from using link_to for this as well:
<%= link_to 'Export POINT', your_route_path %>

Submit form using link_to in rails

I'm trying to submit a form using link_to as follows:
<%= form_for(#post, :url=> '/post/action', :method=> 'post', :html => {:id=>'form_id'} ) do |f| %>
....
<%= link_to 'submit', "/post/action", :onclick=>"document.getElementById('form_id').submit()" %>
....
but it is not posting the form, it is simply redirecting my form to the specified url. Does anyone know how to do this?
You can use:
<%= link_to 'submit', "#", :onclick => "$('#form_id').submit()" %>
if you are using JQuery and a later version of rails.
Above will work but if you have a really long page it will navigate to top of the page because of "#" so if you want to avoid that you can do:
<%= link_to 'submit', "", :onclick => "$('#form_id').submit()" %>
I think both things happen. The browser starts to submit the form, but it also follows the link's href. You can fix it by linking to # instead of /post/action...
...however, I don't recommend doing it. There are a few better approaches:
First, you can use a button instead of a link. You'll have to style it to make it look like a link, but that should not be a problem. It will be better, because it won't break the Principle of Least Surprise (people who read the code expect forms to be submitted with buttons) and you won't need the JavaScript.
If you insist on using a link, you should at least move the JavaScript code from the view to a JavaScript file. Then have this behavior added unobtrusively (although, you won't have a good fallback with the link). Assuming you're using jQuery, it should be as simple as:
$(document).on('click', '[data-submit-form]', function(e) {
e.preventDefault();
$(this).closest('form').submit()
}

Getting button_to to act like link_to - Rails

I have a button_to call that I essential want to act like a link_to call. I set it up to use a get request but when I click it, in the URL a '?' appears on the end of the URL.
Ex: /admins/new? instead of /admins/new. How do I remove this ? from the URL so it behaves just like a link_to link?
Button_to code
<%= button_to "New Admin", new_admin_path, :method => :get %>
Take a look at your own question:
The red arrow points to elements that look like a button but in fact are links, just styled. You can do the same in your app.
You can customize the method in button_to like such:
<%=button_to "Admin",new_admin_path,{method: :get}%>

Rails button_to fails with path doesn't exist for a path that exists

Writing my first, very simple Rails application, a simple admin app to track work for one of our departments. The generated index page for people has a link_to on it to add a new person. I tried to change that to button_to and it fails saying the path /people/new doesn't exist, though obviously it does since link_to goes to the same place.
I'm using Rails 3/Ruby 1.9.2. I have this code on my /app/views/people/index.html.erb page:
<%= link_to 'New Person', new_person_path %>
<%= button_to "New", :controller => "people", :action => "new" %>
The link_to works. The button_to fails with this:
Routing Error
No route matches "/people/new"
Also tried just
<%= button_to 'New Person', new_person_path %>
Same error. Odd.
button_to defaults to the post method. Try putting :method => :get in there. This is why link_to works.
There's a good explanation for this, as always :)
link_to uses GET as default, where button_to uses POST. And there's no POST route that matches, only a GET route.
If you want to use button_to, you can add :method => :get to your buttons params and it will use GET.
Did you set up your routing options in config/routes.rb? Check if you have this in your routes.rb file:
resources :people
Check this guide for more informations about how routes work.
Is your button_to inside a form? button_to creates a form of its own so this would create a form within a form and likely break routing.
