Ruby on Rails - Passing values to a link_to

Question

I'm a RoR beginner and am using Rails 3.2.3. I have a search form on my page and it performs a get request and filters the results correctly. I want to add the possibility of also searching Products by dates. I inserted a date_select and am able select the date and when the page refreshes after the search, the chosen dates are still there on the date_select, as I am able to get them through `params`. However, my issue is that when the page renders the products, they have a link_to to their show action. My goal is to also pass alongside the url the dates that were selected to perform the search on that link_to. For ex, if the user selects a date of 20-06-2012 to 25-06-2012 it only shows products inserted on that time frame (and all those params are on the url) But the link to show action of each displayed product is only: ``` link_to <%= link_to product.name, product%> ``` which renders `http://localhost:3000/products/24` (por example) what I want to render/show is something like: ```…

Accepted Answer

If you want to pass arbitrary parameters to the following call ``` <%= link_to product.name, product %> ``` you need to invoke the path method explicitly instead of using the implicit version. The line above is equivalent to ``` <%= link_to product.name, product_path(product) %> ``` Then you can pass parameters ``` <%= link_to product.name, product_path(product, :from => 'whatever', :to => 'whatever') %> ```
