I want the link which goes to
http://example.com/shop/:shop_name
so it should be something like this.
<%= link_to "Shop", req.host + "/shop/"+ #shop.shop_name , :class => 'btn' %>
I don't want to use something_path or something_url here.
I just want to create url link from current host, and variable.
How can I?
UPDATE:
<%= link_to "Shop", request.host + /shop/ +#shop.shop_name , :class => 'btn' %>
This takes me to
http://www.example.com/shop/www.example.com/shop/walmart
try with,
<%= link_to "Shop", "/shop/"+ #shop.shop_name , :class => 'btn' %>
Why don't you want to use url helpers? Doing it by hand is error-prone.
Simply put this to routes.rb
get "shop/:name", to: "shops#show", as: "shop_name"
Then you can use this in your templates:
<%= link_to "Shop", shop_name_path(#shop.shop_name), :class => 'btn' %>
In the show action of shops controller just fetch the name param:
shop_name = params[:name]

<%= link_to (:controller => "company_stuff", :action => "index", :anchor => :menu), :class => 'links' do %>
<li>Terms of Use</li>
<% end %>
I am having difficulty linking a page which is on a different controller and also the link is an anchor. Basically the controller is called company_stuff the action is index and the anchor is called #terms
The problem was that the :controller :action :anchor was not being passed through as a hash, separate from the CSS class
Below is the solution
<%= link_to "Terms Of Use", {:controller => "company_stuff", :anchor => "terms"}, :class => "links" %>
I believe you can try something like this
<%= link_to index_company_stuff_path + "#terms", :class => 'links' do %>
<li>Terms of Use</li>
<% end %>
Or
<%= link_to index_company_stuffs_path + "#terms", :class => 'links' do %>
<li>Terms of Use</li>
<% end %>
Depending on your controller name and route.

I would like to be able to add an additional query string parameter on submit that is the same as the value of the classrooms_search_textbox that the user will type. How do I do this?
<%= form_tag classrooms_path, :method => :get, :id => "classrooms_search_form" do %>
<%= text_field_tag "classrooms_search_textbox", "Find a classroom" %>
<%= submit_tag "Find", :id => "classrooms_search_button", :class => "button" %>
Do I need to add a hidden_tag (and if so, how would I go about doing this?) or can I just add to the classrooms_path somehow?
Thanks!
Since you're sending it your controller first, then you can just manipulate the params in your controller method before sending it off:
params[:classrooms_query] = params[:classrooms_search_textbox]
And then go ahead and use those params to send off to the other service. There's no need to add hidden field tags or use some fancy JS code.
<%= form_tag classrooms_path, :method => :get, :id => "classrooms_search_form" do %>
<%= text_field_tag "classrooms_search_textbox", "Find a classroom" %>
<%= hidden_field_tag "classrooms_query" %>
<%= submit_tag "Find", :id => "classrooms_search_button", :class => "button" %>
$('#classrooms_search_form').submit(function() {
$('#classrooms_query').value($(classrooms_search_textbox.value());
});
That would achieve what you want. Nonetheless, maybe it is in your interest to refactor the controller or view so that it doesn't have this kind of conflicts.
I have a view that uses link_to to pass parameters to a controller. The url is a variable. Something is not working. I'd appreciate any clues. Thanks!
<% url1 = dialogs_path(#dialogId) %>
<%= url1 %>
<%= link_to "Go!", url1(:uid1 => #uid1, :uid2 => #uid2), :id => "my_link" %>
url1 displays correctly. However, executing link_to crashes.
You should use dialog_path(#dialogId) instead.
You're trying to view a particular object, it's singular and what rails expects.
Take a look here :
http://guides.rubyonrails.org/routing.html#paths-and-urls
The way you use url confuses me, try something like this :
<%= link_to "Go!", dialog_path(#dialogId, :uid1 => #uid1, :uid2 => #uid2), :id => "my_link" %>
The url1 should be defined as:
<% url1 = dialogs_path(#dialogId)+'?uid1=' + #uid1 + '&uid2=' + #uid2% , :id => "my_link" %>
And the link_to should be:
<%= link_to "Go!", url1, :id => "my_link" %>
I'm using link_to in RoR 3
When I use it like this, it works fine:
<%= link_to "Add to your favorites list",:controller =>
'favourite_companies', :action =>'create',
:company_id=>"#{#company.id}",
:company_name=>"#{#company.company_name}" %>
But I would like to pass in a class as well
however, this is not working for me. The class works, but it breaks the link. Any ideas?
<%= link_to "Add to your favorites list",{:controller =>
'favourite_companies', :action =>'create'},
:company_id=>"#{#company.id}",
:company_name=>"#{#company.company_name}",
:class=>"ui-button-text button_text"} %>
<%= link_to "Add to your favorites list",{:controller =>
'favourite_companies', :action =>'create'},
:company_id=>"#{#company.id}",
:company_name=>"#{#company.company_name}",
:class=>"ui-button-text button_text"} %>
try this
<%= link_to "Add to your favorites list", :controller =>
'favourite_companies', :action =>'create',
:company_id=>"#{#company.id}",
:company_name=>"#{#company.company_name}",
{ :class=>"ui-button-text button_text" } %>
Since the :class should be in :html_options (refering to API)
link_to(body, url, html_options = {})
The proper way of doing what you have is as follows:
link_to "Foo", { URL_FOR PARAMS HERE }, :class => "bar"
As far as setting the controller and action manually like this, well, it's crap. Rails builds url helpers for you; use them and save yourself some time, energy, and add clarity, all at once:
link_to "Foo", favourite_companies_path(#company), :method => :post
What you're doing with the string interpolation is a bad idea too…it's just wasteful and cluttered for no reason at all. The following is the same, just better:
link_to "Foo", :company_id => #company.id, :company_name => #company.name
As far as why your link wasn't working, if wrapping it in a div helped it sounds like you have a problem with your HTML structure, not the link_to syntax.
I'm using a link_to do-end block so the above previous solutions didn't work for me.
If you want to embed other tags in your a tag, then you can use the link_to do-end block.
<%= link_to favourite_companies_path(:company_id => #company.id, :another_url_param_here => "bar"), { :class => "ui-button-text button_text", :title=> "We can have more html attributes as well" } do %>
<i class="fa fa-star"></i>
<%= #company.company_name %>
<% end %>
In this case it's
<%= link_to path(url_params), html_options = {} do %>
<% end %>
Be careful because in Rails 5 the above methods will still result in a wrong URL generation. The controller and action need to be put in a literal hash in order for it to work in Rails 5. What you will have should be something like this
<%= link_to "Add to your favorites list",
{ controller: "favourite_companies", action:"create"},
company_id: #company.id,
company_name: #company.company_name,
class: "ui-button-text button_text" %>
I am using link_to img tag like following
<%= link_to image_tag("Search.png", :border=>0, :class => 'dock-item'),
:action => 'search', :controller => 'pages'%><span>Search</span></a>
Which results in following html
<a href="/pages/search"><img alt="Search" border="0" class="dock-item"
src="/images/Search.png?1264132800" /></a><span>Search</span></a>
I want the class="dock-item" to go to the <a> tag instead of the img tag.
How can i change this?
Update:
<%= link_to image_tag("Search.png", :border=>0), :action => 'search',
:controller => 'pages', :class => 'dock-item' %>
results in
<a href="/pages/search?class=dock-item"><img alt="Search" border="0"
src="/images/Search.png?1264132800" /></a>
hi you can try doing this
link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, {class: 'dock-item'}
or even
link_to image_tag("Search.png", border: 0), {action: 'search', controller: 'pages'}, class: 'dock-item'
note that the position of the curly braces is very important, because if you miss them out, rails will assume they form a single hash parameters (read more about this here)
and according to the api for link_to:
link_to(name, options = {}, html_options = nil)
the first parameter is the string to be shown (or it can be an image_tag as well)
the second is the parameter for the url of the link
the last item is the optional parameter for declaring the html tag, e.g. class, onchange, etc.
hope it helps! =)
Just adding that you can pass the link_to method a block:
<%= link_to href: 'http://www.example.com/' do %>
<%= image_tag 'happyface.png', width: 136, height: 67, alt: 'a face that is unnervingly happy'%>
<% end %>
results in:
<a href="/?href=http%3A%2F%2Fhttp://www.example.com/k%2F">
<img alt="a face that is unnervingly happy" height="67" src="/assets/happyface.png" width="136">
</a>
This has been a life saver when the designer has given me complex links with fancy css3 roll-over effects.
Best will be:
link_to image_tag("Search.png", :border => 0, :alt => '', :title => ''), pages_search_path, :class => 'dock-item'
this is my solution:
<%= link_to root_path do %>
<%= image_tag "image.jpg", class: "some class here" %>
<% end %>
Easy:
<%= link_to image_tag("Search.png", :border=>0), :action => 'search', :controller => 'pages', :class => 'dock-item' %>
The first param of link_to is the text/html to link (inside the a tag). The next set of parameters is the url properties and the link attributes themselves.
I tried this too, and works very well:
<%= link_to home_index_path do %>
<div class='logo-container'>
<div class='logo'>
<%= image_tag('bar.ico') %>
</div>
<div class='brand' style='font-size: large;'>
.BAR
</div>
</div>
<% end %>
To respond to your updated question, according to http://api.rubyonrails.org/classes/ActionView/Helpers/UrlHelper.html...
Be careful when using the older argument style, as an extra literal hash is needed:
link_to "Articles", { :controller => "articles" }, :id => "news", :class => "article"
# => Articles
Leaving the hash off gives the wrong link:
link_to "WRONG!", :controller => "articles", :id => "news", :class => "article"
# => WRONG!
The whole :action =>, :controller => bit that I've seen around a lot didn't work for me.
Spent hours digging and this method definitely worked for me in a loop.
<%=link_to( image_tag(participant.user.profile_pic.url(:small)), user_path(participant.user), :class=>"work") %>
Ruby on Rails using link_to with image_tag
Also, I'm using Rails 4.
Hey guys this is a good way of link w/ image and has lot of props in case you want to css attribute for example replace "alt" or "title" etc.....also including a logical restriction (?)
<%= link_to image_tag("#{request.ssl? ? #image_domain_secure : #image_domain}/images/linkImage.png", {:alt=>"Alt title", :title=>"Link title"}) , "http://www.site.com"%>
Hope this helps!
<%= link_to root_path do %><%= image_tag("Search.png",:alt=>'Vivek',:title=>'Vivek',:class=>'dock-item')%><%= content_tag(:span, "Search").html_safe%><% end %>
You can also try this
<li><%= link_to "", application_welcome_path, class: "navbar-brand metas-logo" %></li>
Where "metas-logo" is a css class with a background image
