routes

I believe I messed up the routes in one of my models.

Should I delete the model and try again?

Thanks,

Joe

Routes do not belong to a model, they map request pathes to actions in controllers, so can you please go into a little bit more detail?

As Nobert says they are independent. Post your routes.rb, where the view is you want the route to go to and say what you were expecting.

Ruby on Rails Guides: Rails Routing from the Outside In may help.

Also if you have not done so do the Getting started guide on the rails website. See it through to the end. I got confused half way when I did it but kept with it and its a great foundation.

I myself have a habit of just diving in and doing stuff. Knowing the conventions rails has and the rails way saves a lot of time in the medium term.

Uh, any particular reason to post a link to a guide for a version of Rails that's been unsupported for a very long time?

ok, it looks like my other form


<%= simple_form_for @gallery do |f| %>
    <% if @gallery.errors.any? %>
        <div id="error_explanation">
          <h2>
            <%= "#{pluralize(@gallery.errors.count, "error")} prohibited this image from being saved:" %>
          </h2>
          <ul>
            <% @gallerys.errors.full_messages.each do |msg| %>
                <li>
                  <%= msg %>
                </li>
            <% end %>
          </ul>
        </div>
    <% end %>






this is the error i'm getting...

I’m using… in my routes file.



get resources :gallery






Thanks,

You do have this in your routesfile literally? Seems invalid for me.

Also As far as I can remember the convention, `resources` needs the plural name, not the singular name. But I haven't used rails since about 3.x-ish.

8

RIght, I tried resources galleries, resources gallerys

But all come up with other errors. My post controller and views work, this gallery controller seems to look the same? (I don’t get it).

Thanks,

Joe

Doesn’t running the scaffold command put the route in the routes file for you?

rails routes will show you all configured routes, which may help

yes, I know that. :slight_smile:

12

But you did not understand… If you had shown the output, it might be easier for us to see what exactly went wrong.

13

+1

post output from ‘$ rails routes’, it will really help people help you.

also 'NoMethodError in Gallery#new sounds like the new method is missing from the Gallery controller so posting that would also be good.

Thanks, I’ll add the post the results of my routes tonight. (when I’m at home).

15

Why is the 'get' there?

I asked before, but that wasn't heard, perhaps increasing the noise might help?

I’m removing most of the “noise” from your output and focussing on the gallery-relevant bits:

here’s the output of my routes… (sorry about the formatting)

Prefix Verb URI Pattern Controller#Action

gallery_index GET /gallery(.:format) gallery#index

POST /gallery(.:format) gallery#create

new_gallery GET /gallery/new(.:format) gallery#new

edit_gallery GET /gallery/:id/edit(.:format) gallery#edit

gallery GET /gallery/:id(.:format) gallery#show

PATCH /gallery/:id(.:format) gallery#update

PUT /gallery/:id(.:format) gallery#update

DELETE /gallery/:id(.:format) gallery#destroy

the key bit to notice is that the index route is “named” gallery_index because you used:

resources :gallery

and :gallery is the singular form

You very likely want to say instead:

resources :galleries

which will give you similar routes except from the index:

Thanks. What should I do to fix it? Should I re-run the generator?

You could start by trying Rob's suggestion.
