I have a mailer template in rails. I am trying to use the url of a paperclip attachment: <%=item.picture.url%>
OFcourse, this only renders the path which is pretty useless in an email. I need to get the absolute url.
Also since I am using rake to run the task, there is no request per se.
I remember setting the default host in
config.action_mailer.default_url_options = { :host => 'sitename.com' }
How do I access this value in the mailer template?
you can use helper in action-mailer and absolute url helper is root_url.
Try this
You can get the host name using the below line of code
request.host

I am making rails app and I need to get just hostname of my URL from my one of Rails controllers.
If my URL is http://www.example.com/path/0,then I just want to extract www.example.com part. How can I do this? I found request.base_url but this returns http://www.example.com which I do not want.
In javascript there is a function, window.location.hostname. I wonder there is a equivalent in Ruby on Rails.
You can use request.host to get exact your URL which you want.
And you can use request.port to get your port from url
The URI module can do this for you.
uri = URI("http://www.example.com/path/0")
uri.host # => "www.example.com"
I am using Rails 4.2
We can get host and port with one method
request.host_with_port
=> "localhost:3002"
In my app I have a few APIs that under api domain. Now in one of the API I want to generate a url that pointing to the main domain, say
test.com/blabla...
I tried to use url_for but seems the default root_url or request.host is in api domain. Url_for will make it to be
api.test.com/blabla..
while I want it to be
test.com/blabla...
Url_for can take a parameter
host: ...
to set it to be test.com/, the question is how can I get the root/base url (test.com) for host? root_url or request.host are all api.test.com.
Any ideas? Thanks.
Just so that it's useful to someone else , i came across this today
request.base_url
gives the full path in local as well as on live .
request.domain
gives just the domain name so it sometimes kinda breaks the link while redirecting
According to this you can do request.domain
Simplest alternative method:
include in you're class
include Rails.application.routes.url_helpers
create function or just use root_url to get app root/base url:
def add_host_prefix(url)
URI.join(root_url, url).to_s
end
finally: add
Rails.application.routes.default_url_options[:host] = 'localhost:3000'
in:
Your_project_root_deir/config/environments/development.rb
although helpers can be accessible only in views but this is working solution.
request.domain fails on CF it given domain url not base url
When sending emails (for example for 'Reset password instructions') using Devise, i need to know current domain URL, and set that value into mailer's template.
request.url doesn't work for me.
Assuming, this Rails application is accessibly from multiple URLs.
Any ideas?
Request object is not available in the mailers. You will need to set up the host in the environment configuration file with something like:
ActionMailer::Base.default_url_options[:host] = 'myhost.com'
in my config/application.rb file I have a line:
config.action_mailer.default_url_options = { :host => 'example.com' }
How can I configure the host attribute for default url options automaticaly from the domain, where my Rails app is hosted ?
It has to be explicitly specified somewhere because how else would rails know what the domain is?.. A request through the browser (or curl, or whatever) will have a host which rails knows about, but if you load up rails console, what would the domain be?
If you're using something like capistrano, you could write a task to create an initializer which sets the mailer url depending on the host(s) you've set in your deploy recipe.
i want to send an email to user after he sign-up with code.for ex
http://192.168.1.51:3000/logins/activate/435546dgfd757676657 #link contains in an email
how can i create the above URL in my notifier model.
i know following way
url_for :controller=>'logins', :action=>'activate', :id=>'435546dgfd757676657' , :host=>'http://192.168.1.54:3000'
Which is working properly.
what i want that host should not be hard coded. How can i get host with port in a model.
In controller i can find it using follwing ways
request.host_with_port
Please provide me correct ruby way for doing same.
You can define the host in your environment.rb file.
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
As your host probably changes depending of your environment (development, test, production), it's better to put that config line inside the environment file.
After that, every link in emails will be made with that host. You don't have to provide it in the view anymore.
