I am trying to access a url helper that I'm using in my event controller like this event_url(event).
Is there a way to access this in my event model?
Something like this?
event_url(self)
Im using rails v2.3.11.
Try adding this in your model
include ActionController::UrlWriter
You also need to add config lines to env configs:
development.rb
config.action_controller.default_url_options = {:host => "localhost:3000"}
production.rb
config.action_controller.default_url_options = {:host => "example.com"}

In a controller I call a service like:
MyService.call
In the MyService.call method I want to use a url helper:
Rails.application.routes.url_helpers.something_url
However, I get the error:
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
in config/environments/development.rb I have:
config.action_mailer.default_url_options = { host: 'localhost:3000' }
config.action_controller.default_url_options = { host: 'localhost:3000' }
What should I set not to get the error?
You could set the host in the config files as:
Rails.application.routes.default_url_options[:host] = 'your_host'
This will set the default host not just for action_mailer and action_controller, but for anything using the url_helpers.
According to this thread, whenever using route helpers, they don't defer default_url_options to ActionMailer or ActionController config and it is expected that there will be a default_url_options method in the class. This worked for me:
class MyService
include Rails.application.routes.url_helpers
def call
something_url
end
class << self
def default_url_options
Rails.application.config.action_mailer.default_url_options
end
end
end
Note that you can use action_mailer or action_controller config depending which you've configured.
Missing host to link to! Please provide the :host parameter, set
default_url_options[:host], or set :only_path to true
I randomly get this error at time, generally restarting the server fixes the issue for a while, and then it shows up again.
I have added
config.action_mailer.default_url_options = "localhost:3000", in the development and test.rb files.
Also, I have used include Rails.application.routes.url_helpers
in one module to get access to the routes, I read this could be the reason I get these errors but removing it will leave me with no access to the routes.
The module is for the datatables gem.
For Rails 5, use:
Rails.application.routes.default_url_options[:host] = "XXX"
You can put this in a config/environments/ file (or any other initializer), or e.g. at the beginning of config/routes.rb.
You should write in the following way
For Development(development.rb)
config.action_mailer.default_url_options = { :host => "localhost:3000" }
In production (production.rb)
config.action_mailer.default_url_options = { :host => "myproductionsite.com" }
I had a similar error. The problem is in your configuration.
Try rewriting your configuration for your development.rb and test.rb like this:
config.action_mailer.default_url_options = { host: "localhost", port: 3000 }
Also check that your configuration in production.rb is written correctly like this:
config.action_mailer.default_url_options = { host: 'myherokuapp.herokuapp.com' }
You have updated the default url options for action mailer.
URL helpers will take the option from action_controller settings.
config.action_controller.default_url_options = .....
BR
I want to set some of the options on config.action_mailer.default_url_options in an initializer. However, the problem is that this value may be nil, or it may be a hash with other options.
Example of the problem when using the reccomended method:
# config/application.rb
config.action_mailer.default_url_options = {protocol: 'https'}
# config/environments/production.rb
config.action_mailer.default_url_options = {host: "example.com"}
# config/environments/development.rb
config.action_mailer.default_url_options = {host: "staging.example.com"}
Now default_url_options doesn't have ssl: true set.
The only way to accommodate both possibilities as far as I can tell is to set it to an empty hash if it's null, then add to the hash like so:
config.action_mailer.default_url_options ||= {}
config.action_mailer.default_url_options[:host] = 'example.com'
This is not dry, and has to be done anywhere you wish to set this option unless you are absolutely sure none of the options have been set before and nobody will attempt to set one of the options in the future in a file which is loaded before this one.
Is there a better way to do this?
You can do something like in env file.
config.action_mailer.default_url_options.merge(host: "staging.example.com")
Devise confirmation_url is producing just a relative url with no domain such as:
http://users/confirmation?confirmation_token=...
I tried changing
confirmation_url(#resources, :confirmation_token => #resource.confirmation_token)
to
confirmation_url(:confirmation_token => #resource.confirmation_token)
but it produces the same url. I upgraded to devise 2.2.3 but same outcome. Rails 3.1.4
Update:
I have set in my production.rb:
config.action_mailer.default_url_options = { :host => 'mysubdomain.mysite.com' }
and I tried setting
before_filter set_actionmailer_host
def set_actionmailer_host
ActionMailer::Base.default_url_options[:host] = request.host_with_port
end
to no avail in application controller (https://github.com/plataformatec/devise/issues/1567)
Update:
This occurs in both development and production.
Update
I can't understand why Devise isn't using the template in app/views/devise/mailer/confirmation_instructions.html.haml If I could edit that I could append the host manually: 'http://mysite.com/' + confirmation_url(...
I tried setting the scoped views setting but it didn't have any effect
This is a disaster, users can't confirm their registration :(
You might have missed to add the default url hosts to your environment config-files. When you run the rails g devise:install command you usually receive those instructions.
# config/environments/development.rb
# Default actiomailer url host (required by devise)
config.action_mailer.default_url_options = { host: 'myapp.dev' }
You need this setting for all your environments.
# config/environments/production.rb
# Default actiomailer url host (required by devise)
config.action_mailer.default_url_options = { host: 'myproductionapp.com' }
I would like to do something like this
config.default_host = 'www.subdomain.example.com'
in some of my configuration files, so that object_url helpers (ActionView::Helpers::UrlHelper) produce links beginning with http://www.subdomain.example.com
I have tried to search the docs but I did not find anything except ActionMailer docs and http://api.rubyonrails.org/classes/Rails/Configuration.html which is not useful for me, because I do not know in which pat to look. Is there a place which describes the whole structure of Rails::Initializer.config?
asset_host doesn't work for urls
You need to override default_url_options in your ApplicationController (at least in Rails 3)
http://edgeguides.rubyonrails.org/action_controller_overview.html#default-url-options
class ApplicationController < ActionController::Base
def default_url_options
if Rails.env.production?
{:host => "myproduction.com"}
else
{}
end
end
end
Define the default host in your environment config:
# config/environments/staging.rb
MyApp::Application.configure do
# ...
Rails.application.routes.default_url_options[:host] = 'preview.mydomain.com'
# ...
end
Then you can create a URL anywhere in your app:
Rails.application.routes.url_helpers.widgets_url()
Or include the URL helpers in your class:
class MyLib
include Rails.application.routes.url_helpers
def make_a_url
widgets_url
end
end
If you don't define the default host, you will need to pass it as an option:
widgets_url host: (Rails.env.staging? ? 'preview.mydomain.com' : 'www.mydomain.com')
It's also useful to specify things like the protocol:
widgets_url protocol: 'https'
Another way is to set it like this
# config/production.rb
config.action_controller.default_url_options = { host: 'myproduction.com' }
You can easily set :host or/and :only_path parameter for every url_helper.
yours_url(params, :host => "http://example.com", :only_path => Rails.env.test?)
This way you are not setting global default_url_options in your environments, unless you want that.
In Rails 6.1 (at least), application-wide default_url_options can be set as follows:
# config/environments/development.rb
Rails.application.default_url_options = { host: 'localhost', port: 3000 }
Rails.application.configure do
# ...
end
See: https://github.com/rails/rails/issues/29992#issuecomment-761892658
As far as I know, the *_url helpers use the server's configured host name. So for example if my Apache installation is accepting requests for this Rails app at http://www.myapp.com/ then Rails will use that address. That's why the *_url methods in a development environment point to http://localhost:3000 by default.
The asset host suggested in the previous answer will only affect the image_tag, stylesheet_link_tag and javascript_link_tag helpers.
NSD's solution is how I do it, but I had to add a block to make it work with https:
config.action_controller.asset_host = Proc.new { |source, request|
(request ? request.protocol : 'http://') + "www.subdomain.example.com"
}
There's this, but I'm not terribly sure if they're the helpers you're referring to:
ActionController::Base.asset_host = "assets.example.com"
