I have a model called resource in my rails app and in need of modifying the return value of the helper *resource_path*, I've read some docs and SO Q/A and they're generally suggesting put the customized helper in *app/helpers/application_helper.rb*. The thing bothers me is that what do I do with the old auto generated helper? should I do something like
undef resource_path
before I go ahead and write my own helper? Currently I have a *resource_path* method defined within ApplicationHelper, interestingly when I open rails console, app.resource_path and helper.resource_path giving me different result.
Also, I'd like to hear a deeper explanation on how *_path* helpers implemented and how they are related to *link_to* helper, as the source code are kinda hard to read with so many meta programming techniques involved
Yes, you are able to do it like following:
resources :photos, as: 'images'
in your config/routes.rb file.
More details you can find here http://guides.rubyonrails.org/routing.html especially 4.3 Overriding the Named Helpers

We are in the process of taking a few pages out of our rails app to be served separately (they are a few static pages with some content being managed through a cms). The urls will stay the same. Our own routing system in front of the servers will decide which request should go to the rails app and which to the static part.
My question is about path helpers that we use quite a bit throughout the rails app, such as link_to about_path that generate mahwebsite.com/about. As I understand I can just leave them be, they will still generate correct urls. My only concern is that for them to work I'll have to keep the routings in the routes file, which will have to be connected to the dummy controller methods. Seems like a lot of redundant code just to fool rails into creating path helpers.
Alternatively, I can hard-code links to the static pages. But before I start replacing a whole lot of code, I'd like to know if there is a clean Railsy way to keep the path helpers without having to route to the redundant controllers.
Thanks.
Why not just create your own helper method? E.G.
# application_controller.rb
def about_path
"mahwebsite.com/about"
end
helper_method :about_path
alias_method :about_url, :about_path
This will overwrite any Rails helper method and do exactly what you're after :)
Hope this helps - give me a shout if you've any questions or comments.
How about
resources :custom_pages, only: [:your_options] do
get :view/:page_id_or_whatever_for_identify
end
and do the following content with the controller?
I'm trying to translate the routes in a Rails application. I tried with i18n_routes, but I had some problems with translating actions that didn't depend on a resource. In the end, I solved it without using i18n_routes, as explained here.
The issue now is that I don't find the way to translate scopes. This is my routes.rb:
scope "sport" do
translated_named_route 'it_is_healthy', 'sport#it_is_healthy'
translated_named_route 'it_is_social', 'sport#it_is_social'
end
How to translate sport? I tried with i18n_routes again, but I don't see how to translate the scope. Thanks!
If you are open to using a gem for this, I would recommend using
https://github.com/francesc/rails-translate-routes
The readme is fairly comprehensive and it definitely covers namespaces and scopes in the routes as well.
I'm a total noob to rails and I'm trying to understand a project I'm working on. I've found a method named cv_member_url in one of the views, but I can't for the life of me figure out where it is defined... One thing I do know about rails is that it is a very flexible language so it could be some sort of gem creating this method.
Any ideas where this method may have come from? (or better yet, how I can add others)
Thank you!
Do you have a model called CvMember? If so, the method is probably a named route for that model. See here for more info:
http://guides.rubyonrails.org/routing.html#paths-and-urls
To see all your named routes, you can run
rake routes
Those are named routes which are automatically defined based on what you have in routes.rb. *_url should be used in the controller, and *_path should be used in the views. Here's some more info from the official rails guide.
Assuming you can run this in development: You should put a breakpoint on it and step inside. Most likely it is dynamically defined or maybe in plugin.
Is there a method like "full_url" such that #comment.full_url or full_url_for(#comment) returns "http://www.host.com/comments/id" where www.host.com is the default host domain and id is #comment.id. Or, if not, what would be an elegant way to generate this url string?
I'm pretty new at Rails, most of the methods I've learned insert the tag and other markup.
url_for is not helping because I can't do something like the following:
url_for(#comment, {:only_path => false})
I've spent way too much time trying to figure this out. It came down to either hacking or asking for the right way on SO. Here I am.
If you are setting up your routes correctly in your config/routes.rb file then you should have access to named routes in your controller and in your views. Which should mean that all you should need to do is:
comment_path(#comment)
Or for the full url
comment_url(#comment)
To see a list of all of the routes from the command line, you can type rake routes from the project root. Welcome to rails! Here is a good resource for rails 3 routing: http://guides.rubyonrails.org/routing.html

I would to nest some helper methods to simplify my application_helper, for example I have a bunch of methods dealing with currencies which apply for the entire app and I would like to put in the currencies_helper and then simply include that entire helper into the application helper.
How can I do this?
I tried:
helper :currencies
and got
undefined method `helper' for ApplicationHelper:Module
Helpers in rails are just modules which get included in controllers to help share functionality between them. There's been some weirdness around helpers in rails 3, so depending on what version you're running things may or may not work as you expect out the box.
Essentially what you want to do is add helper :all to your application_controller which will include ALL helpers in ALL your controllers. If this isn't what you want you can specify the specific helpers you want helper :currencies for example.
In the rails 3 betas helper :all was the default behavior, but I think they've reverted that in the latest release.
There's a great article that discusses how this works in rails 2, but there may be differences in rails 3, but it should be a good starting point.
