Rails help creating redirecting action and route - ruby-on-rails

I am trying to create a route and a action that redirects the params.
Example when a user visits: www.mywebsite.com/photographer/flv/:ID/:filename
I want the user to be redirected to: www.someotherwebsite.com/photographer/flv/:ID/:filename
I have tried to accomplish with this solution without luck:
My controller URL:
def videore
redirect_to www.whateverwebsite.com + params[:all]
end
And in routes:
match '/photographer/flv/:ID/:filename' => 'URL#videore'

This should do it:
In your controller action:
def videore
redirect_to "http://www.whateverwebsite.com/photographer/flv/#{params[:id]}/#{params[:filename]}"
end
And in routes:
match '/photographer/flv/:id/:filename' => 'url#videore'
This assumes, of course, that 'url' is the name of your controller

From the Ruby on Rails Guide:
match "/stories/:name" => redirect("/posts/%{name}")
In all of these cases, if you don’t provide the leading host
(http://www.example.com), Rails will take those details from the
current request.
So redirecting to another TLD should work like this (no action in your controller required):
match '/photographer/flv/:ID/:filename' => redirect("http://www.someotherwebsite.com/photographer/flv/%{ID}/%{filename}")

Passing params using redirect to different action in controller

This is first action in controller:
def investor_following
#investor = params[:user][:investor_id]
# blah
end
def change_amount
investor = "xyz"
redirect to :action => :investor_following, :user[:investor_id] => investor
end
I am getting error how can I redirect to action investor following, what would be right syntax to do with params.
You should create a named route for your action in your routes.rb. I'm not sure what you investor_following function will do, so I am not certain if it should be a GET, POST, or PATCH. If you intend to modify your model, use a POST/PATCH, if not, use a get.
Once you have a named route, you will get a path helper like investor_following_path which you can send parameters as ruby objects:
#routes.rb
get '/investor_following', to: 'controllername#investor_following', as: 'investor_following'
#in your controller
redirect_to investor_following_path(user: {investor_id: investor})
This is untested but in general what you should do.
Here is info on redirect_to:

Here is the info on routing for your named path:

Use only a single controller in rails app

I'm trying to develop an app where I only want one controller, and use anything in the url as an argument to that controller.
I've read that normally the url is parsed as GET controller/action, as in example.com/controller/action/params, but I would like to use a specific controller and a specific action.
Is there any way essentially to parse a url as example.com/params, always handled by the same action and controller?
There are a couple of examples of this in the Rails guide on routing. The file config/routes.rb is where you set up the mapping from URL's to controllers.
One specific example is this:
match '/:username' => 'users#show'
Any request that doesn't match further up will get routed to the UsersController's show method, with the string passed in the params hash as the value of the username key.
Yes, there is. In your config/routes.rb file define the route:
match "catchall/*page", :to => "catchall#respond"
Then in your controller:
class CatchallController < ApplicationController
def respond
end
end
I think this is bad idea, but you can do this, using render action:
def index
if self.class.instance_methods(false).include? params[:page].to_sym
render action: params[:page]
else
#error_404
end
end

Rails: Route to custom controller action

I have a really hard time understanding routes and I hope someone can help me.
Here's my custom controller
class SettingsController < ApplicationController
before_filter :authenticate_user!
def edit
#user = current_user
end
def update
#user = User.find(current_user.id)
if #user.update_attributes(params[:user])
# Sign in the user bypassing validation in case his password changed
sign_in #user, :bypass => true
redirect_to root_path
else
render "edit"
end
end
end
and I have the file settings/edit.html.erb and my link
<li><%= link_to('Settings', edit_settings_path) %></li>
The route
get "settings/edit"
doesn't work for this, because then I get
undefined local variable or method `edit_settings_path' for #<#<Class:0x00000001814ad8>:0x00000002b40a80>
What route do I have to give this? I can't figure it out. If I put "/settings/edit" instead of a path it messes up as soon as I'm on a other resource page because the resource name is put BEFORE settings/edit
Thx
Following should do:
get 'settings/edit' => 'settings#edit', :as => :edit_settings
# you can change put to post as you see fit
put 'settings/edit' => 'settings#update'
If you use /settings/edit directly in link, you shouldn't have problem with other resource name being prepended in path. However, without the leading slash, i.e. settings/edit it might have that issue.
Reason why edit_settings_path is not working might be because you didn't declare a named route. You have to use :as option to define by which method you will be generating this path/url.
If you want to explicitly define the route, you would use something like
get 'settings/edit' => 'settings#edit', :as => edit_settings
This statement defines that when a GET request is received for setting/edit, call the SettingsController#edit method, and that views can reference this link using 'edit_settings_path'.
Take some time to read the Rails guide on routing. It explains routing better than any other reference out there.
Also keep in mind the rake routes task, that lists the details of all the routes defined in your application.

Rails route dependent on current user

I'd like to create a rails route for editing a user's profile.
Instead of having to use /users/:id/edit, I'd like to have a url like /edit_profile
Is it possible to create a dynamic route that turns /edit_profile into /users/{user's id}/edit, or should I do thing in a controller or?
You might want to create a separate controller for this task but you could also continue using users_controller and just check whether there is a params[:id] set:
def edit
if params[:id]
#user = User.find(params[:id])
else
#user = current_user
end
end
But you should note that /users normally routes to the index action and not show if you still have the map.resources :users route. But you could set up a differently called singular route for that:
map.resources :users
map.resource :profile, :controller => "users"
This way /users would list all the users, /users/:id would show any user and /profile would show the show the currently logged in users page. To edit you own profile you would call '/profile/edit'.
Since a route and controller serve two different purposes, you will need both.
For the controller, assuming you're storing the user id in a session, you could just have your edit method do something like:
def edit
#user = User.find(session[:user_id])
end
Then have a route that looks something like:
map.edit_profile "edit_profile", :controller => "users", :action => "edit"
This route would give you a named route called edit_profile_path
Tomas Markauskas's answer could work, but here's the answer to your question from the Rails Guide:
get 'edit_profile', to: 'users#edit'
So, when someone goes to www.yoursite.com/edit_profile, it will route to www.yoursite.com/users/edit.
Then, in your controller you can access the user with
#user = User.find(session[:current_user_id])
Assuming you set that session variable when someone logs in. Also, don't forget to check if they're logged in. This will work if your using Resourceful Routing (the Rails default) or not.
Source: http://guides.rubyonrails.org/routing.html
make the route as
get '/users/:id/edit', to: 'users#edit', as: 'edit_profile'
As explained in this link section 'The hard way' :
http://augustl.com/blog/2009/styling_rails_urls/
The url will be
/users/edit_profile
Because the ID is no longer in the URL, we have to change the code a bit.
class User < ActiveRecord::Base
before_create :create_slug
def to_param
slug
end
def create_slug
self.slug = self.title.parameterize
end
end
When a user is created, the URL friendly version of the title is stored in the database, in the slug column.
For better understanding read the link below
http://blog.teamtreehouse.com/creating-vanity-urls-in-rails
write it in any home controler.
def set_roots
if current_user
redirect_to dashboard_home_index_path
else
redirect_to home_index_path
end
end
in routes.rb file
root :to => 'home#set_roots'
match "/find_roots" => "home#set_roots"

Rails redirect_to post method?

redirect_to :controller=>'groups',:action=>'invite'
but I got error because redirect_to send GET method I want to change this method to 'POST' there is no :method option in redirect_to what will I do ? Can I do this without redirect_to.
Edit:
I have this in groups/invite.html.erb
<%= link_to "Send invite", group_members_path(:group_member=>{:user_id=>friendship.friend.id, :group_id=>#group.id,:sender_id=>current_user.id,:status=>"requested"}), :method => :post %>
This link call create action in group_members controller,and after create action performed I want to show groups/invite.html.erb with group_id(I mean after click 'send invite' group_members will be created and then the current page will be shown) like this:
redirect_to :controller=>'groups',:action=>'invite',:group_id=>#group_member.group_id
After redirect_to request this with GET method, it calls show action in group and take invite as id and give this error
Couldn't find Group with ID=invite
My invite action in group
def invite
#friendships = current_user.friendships.find(:all,:conditions=>"status='accepted'")
#requested_friendships=current_user.requested_friendships.find(:all,:conditions=>"status='accepted'")
#group=Group.find(params[:group_id])
end
The solution is I have to redirect this with POST method but I couldn't find a way.
Ugly solution: I solved this problem which I don't prefer. I still wait if you have solution in fair way.
My solution is add route for invite to get rid of 'Couldn't find Group with ID=invite' error.
in routes.rb
map.connect "/invite",:controller=>'groups',:action=>'invite'
in create action
redirect_to "/invite?group_id=#{#group_member.group_id}"
I call this solution in may language 'amele yontemi' in english 'manual worker method' (I think).
The answer is that you cannot do a POST using a redirect_to.
This is because what redirect_to does is just send an HTTP 30x redirect header to the browser which in turn GETs the destination URL, and browsers do only GETs on redirects
It sounds like you are getting tripped up by how Rails routing works. This code:
redirect_to :controller=>'groups',:action=>'invite',:group_id=>#group_member.group_id
creates a URL that looks something like /groups/invite?group_id=1.
Without the mapping in your routes.rb, the Rails router maps this to the show action, not invite. The invite part of the URL is mapped to params[:id] and when it tries to find that record in the database, it fails and you get the message you found.
If you are using RESTful routes, you already have a map.resources line that looks like this:
map.resources :groups
You need to add a custom action for invite:
map.resources :groups, :member => { :invite => :get }
Then change your reference to params[:group_id] in the #invite method to use just params[:id].
I found a semi-workaround that I needed to make this happen in Rails 3. I made a route that would call the method in that controller that requires a post call. A line in "route.rb", such as:
match '/create', :to => "content#create"
It's probably ugly but desperate times call for desperate measures. Just thought I'd share.
The idea is to make a 'redirect' while under the hood you generate a form with method :post.
I was facing the same problem and extracted the solution into the gem repost, so it is doing all that work for you, so no need to create a separate view with the form, just use the provided by gem function redirect_post() on your controller.
class MyController < ActionController::Base
...
def some_action
redirect_post('url', params: {}, options: {})
end
...
end
Should be available on rubygems.
