I have a model that stores a path in the database under a column named "link_path" - for example:
Model.first.link_path == /posts/1
(or, put another way, I am caching the controller/model_id in a database table so Rails doesn't have to build it from scratch.)
In my view, I would like to build up a URL using this path information - for example, http://www.mysite.com/posts/1
I currently have the following code in my view:
<a href="<%= "#{request.protocol}#{request.domain}#{request.port_string}#{post.link_path}" %>">
In development all works as expected both when using POW/Nginx and Webrick - e.g., the link builds up to
http://localhost:3000/posts/1).
However, in production, when I hover over the link, it shows correctly (e.g., mysite.com/posts/1) BUT, when I click on the link, the '/' between .com and posts is strangely missing. The page links to http://mysite.composts/1
Any thoughts on how to fix?
Thanks to BrMcMullin - I wasn't aware I could use the URL helpers without calling the model. Since I don't need the weight of link_to, I ended up changing to
url_for(post.link_path)
instead of manually building up using string interpolation and that seems to work as expected.

In one of my ActiveAdmin pages I have fields containing a URL (either https: or file:). How can I make that when clicked on a new browser tab opens with the corresponding content ?
I tried
link_to('site web', :siteWeb)
but the result is an error message:
undefined method `siteWeb_path' for #<#<Class:0x00007f048201edb0>:0x00007f048202f700>
The problem here is your using a path helper that isn't defined in your routes.rb file. There's an easy way to see what the right path helper is though, just go to your terminal and run:
rails routes
You'll get a bunch of information about each route, along with the specific name of the route path helper function defined in Rails. Then you can just use it like so: https://apidock.com/rails/ActionView/Helpers/UrlHelper/link_to
So my question is that I have a link to 'pages/home' and I click on it, ill go to my home page.
But then I'll try to click again, but the link changes to 'pages/pages/home' and then I'll get a routing error. Is there anyway to fix this using regular old anchor tags? or do i need to use link_to?
edit:
This is how i insert my link into the page.
Home
This is not related to rails, the problem is you use a relative url :
Home
This will lead to <any_path_you're_in>/pages/home.
For it to be absolute, you have to use (note the leading slash):
Home
By the way, it's quite a bad practice to use hardcoded url to your own rails app. You can avoid using #link_to while still taking advantage of rails' routing :
Home
Provided you have a "home" route, of course :
get '/pages/home' => 'pages#home', as: 'home'
This will save you a lot of pain when you decide to restructure your app.
I would like to create custom SEO friendly routes similar to what is used by http://realestate.com.au For example the following page is shown by google when the search term "real estate melbourne" is used:
www.realestate.com.au/buy/in-melbourne,+vic+3000/list-1
I would like use the following format. mysite.com/trips/search/melbourne-to-sydney/01-01-2011
I have configured the routes in my routes.rb file to get it to pick up the correct parameters when a url is entered is this format.
routes.rb
match '/trips/search(/:fl(-to-:tl(/:tripdate)))' => 'trips#someaction'
My question is how do I setup a form in rails 3 to send a GET request using the above url structure. I have tried playing around with to_params though it seems to then change all my edit, show links etc which is not intended. I could build the link using javascript though I guess this would be a hacky option and the site would not work if javascript was disabled.
Is there a neat way to be able to create a GET submit form in Rails 3.1? The fields are select lists containing name and ids.
Thanks for your help.
This will help you immensely with the friendly URL portion

We have been trying to implement shortcodes on an ASP.NET MVC web app that allow users to uniquely invoke a given article/page using an assigned short code.
For e.g.: www.mysite.com/power would map to an actual URL: www.mysite.com/Power/Home/.
I have created various routes throughout the site that map these shortcodes to various actions and controllers within the application. From a shortcode/route point of view, everything is working great.
I, however, noticed a couple of interesting things. I have hyperlinks that I use Url.Action method to generate the URL pointing pages. Many of these pages also have short codes associated with them. For e.g.: I have a link that says:
Go to Power page
This is a page that also has the previously mentioned short-code assigned to it. When I use Url.Action, I ideally expect it to create a link as /Power/Home/Index or /Power/Home, but since I also have a route constraint mapped to it, it now generates the link as /power.
Is there a way I can just use the actual link URL when generating links? I only want short-codes when I am sending out emails etc. I want the site to generate actual URLs.
This may or may not be possible, but I wanted to see if there were any ideas out there that I could use.
Anup
Index and Home are likely defined in your route table as defaults for the Action and Controller element. When you generate the Url it wont include the defaults if they aren't needed.
You could write your own Action overload or helper, which would allow you to take more direct control of the generated URL or action link. You could approach it from two different ways: 1) a helper to generate short-code specific urls and links, and/or 2) a helper to generate the full url and/or link. If Url.Action is returning the short-code version due to your routing configuration, I'd think a good place to start would be the second option, creating a helper/extension method that will generate the full url for you.
Here's how I solved this:
Instead of naming a route with short code to point to the action url, I made the route point to a different Controller action which would then redirect to the actual route that I want it to.
For e.g.: Originally I had the code "power" defined in the route table such that it would point to www.mysite.com/Power/Home.
Now instead of pointing it to that action - Index, controller - Home, area - Power, I make it resolve to: action - Power, Controller - Home, Area - ShortCode.
In the controller now, I simply do a RedirectToAction("Index", "Home", new { Area = "Power" });
This ensures that the actual links to /Power/Home do not resolve to the shortcode "power".
This is a simple fix increased the work by a little bit, but works like a charm.
My application works fine when I have only one parameter.
e.g.
/Product/Index/2
/Report/Sales/08-2009
But it failes when I add one more part to the url. Let's say I want to add the end month-year parameter to the url routing. Mow it becomes:
/Report/Sales/05-2009/09-2009
I do get both parameters in my action method. I parse it and retrieve the data and pass the Model to the View. With this scenario it throws the client side JS error when I try to access any of the form elements. I get "object expected" error. The same view works fine using just first parameter. What could be the issues here?
I also loose the CSS styles when this error occurs.
Thanks
well, without seeing any code at all this is difficult to troubleshoot, but I'd say it's likely because you are referencing your javascript and css files using a relative path like:
../content/scripts/myjavascript.js
Adding the second url parameter has caused the browser to be unable to find the urls because you have added what looks like an extra level of depth to the url.
You should provide absolute urls to your scripts and css files. An easy way to do this is to use the "ResolveUrl" method like so:
<%= ResolveUrl("~/Content/Scripts/myjavascript.css") %>
