I'm trying to get a link_to to generate the full url link of a survey in my sample survey app. The way I'm doing it is this in my mailer view:
<p>The survey is located <%= link_to("here", survey_url(#survey)) %>.</p>
The link that's generated is http://localhost:3000/surveys/2.
However, when the same code is run in production, the link that's generated is http://example.herokuapp.com/surveys/2 when it should be http://example.com/surveys/2.
The config files:
development.rb:
config.action_mailer.default_url_options = { :host => 'localhost:3000'}
production.rb:
config.action_mailer.default_url_options = { :host => 'http://example.com'}
Any idea why heroku is adding .herokuapp to the end of the host url/what I can do to generate the url as http://example.com/surveys/2?

I added the following in my production.rb environment file.
config.action_mailer.default_url_options = {host: "domain.com"}
In my view:
<%= tag("img", src: image_url("logo.png")) %>
However, when I look at the path in my email, I see a image_path, not URL.
http:///assets/logo.png
What am I doing wrong?
This is how it works in my application. Try this
<%= image_tag(attachments['logo.png'].url, style: 'margin: 5px') %>
Try asset_path instead of image_url in production email views.
You need to specify config.action_mailer.asset_host = "domain.com" in production.rb. Then use image_tag in your mailer view.
I'm having problems when resetting a password using Devise.
When I click on 'Send me reset password instructions', I get:
ArgumentError at /users/password
Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
It says that the problem is in /views/devise/mailer/reset_password_instructions.html.erb on line 5.
On line 5 in that file there is:
<p><%= link_to 'Change my password', edit_password_url(#resource, :reset_password_token => #resource.reset_password_token) %></p>
I have no idea how to setup a mailer in Rails although I have tried to. Can anybody help me with this?
Finally, you need to set up default url options for the mailer in each
environment. Here is the configuration for "config/environments/development.rb":
config.action_mailer.default_url_options = { :host => 'localhost:3000' }
You need to specify the host so it can be shown in the confimation email.
You can create a default filter like this:
# application_controller.rb
before_filter :mailer_set_url_options
...
def mailer_set_url_options
ActionMailer::Base.default_url_options[:host] = request.host_with_port
end
Assets are working fine for my web views, but for some reason my Mailer doesn't use the asset pipeline. I am trying to use an image_tag in my mailer view:
=link_to image_tag("logo.png")
However, that renders as
<img alt="logo" src="http://mydomain.com/assets/logo.png">
instead of
<img alt="logo" src="http://mydomain.com/assets/logo-xxxxxxxxx...png">
Am I missing something here?
My settings are:
config.action_mailer.default_url_options = { :host => config.domain }
config.action_mailer.asset_host = "http://" + config.domain
Thank you!
Try to put in your mail template the following instead of the link_to ( the link_to makes no sense because you link here your image to nothing, and I don't see the a href as output in your html) :
= asset_path("logo.png")
also put in your specific environment file :
config.action_mailer.default :content_type => "text/html"
Like this you are sure that you always use HTML as default content type. If u are using images in the mails it is better to put it as html.
I'm using ActionMailer to send a sign up confirmation email. The email needs to contain a link back to the site to verify the user, but I can't persuade Rails to generate a full URL (including the domain etc).
I'm using:
<%= url_for :controller => 'login', :action => 'verify', :guid => #user.new_user.guid, :only_path => false, :host => 'http://plantality.com' %>
in my view
Part b:
In development mode Rails gripes if I don't specify the host explicilty in the link above. But I don't want to do this in production. Any solutions?
To solve the problem to pass a host for generating URLs in ActionMailer, check out this plugin and the reason why I wrote it.
To solve the first issue, use named routes when applicable. Instead of
<%= url_for :controller => 'login', :action => 'verify', :guid => #user.new_user.guid, :only_path => false, :host => 'http://plantality.com' %>
assuming the route is called login, use
<%= login_url(:guid => #user.new_user.guid) %>
Note, I'm using login_url, not login_path.
I'm not sure if it is what you want but in config/environments/development.rb you can specify default options for mailer urls
config.action_mailer.default_url_options = {
:host => "your.host.org",
:port => 3000
}
you can do the same in config/environments/production.rb
I don't know why the previous solutions seem so complicated, but since I'm here why not give my 2 cents...
Go to /config/environments and add:
config.absolute_site_url = 'your site url'
for the respective environment (ie. in development.rb, test.rb, or production.rb). Restart web server.
This allows you to call Rails.application.config.absolute_site_url to get the desired URL. No need for plugins or weird cheat, just store the site url as an application wide variable.
I think its not 100% correct way but this can also be a solution :
See the Using asset hosts section in the documentation. You need to specify an asset_host. You can also construct it dynamically from the request chaining "#{request.protocol}#{request.host_with_port}/login/?guid=#{#user.new_user.guid}"
To generate url, try this
Rails.application.routes.url_helpers.user_url(User.first.id, host: 'yourhost.io')
this will generate url like this:
http://yourhost.io/users/1
As well you can pass some params
expires = Time.now + 2.days
params = {expires: expires}
u = User.first.id
Rails.application.routes.url_helpers.user_url(u, params, host: 'host.com')
will generate:
http://yourhost.io/users/1.expires=2018-08-12+15%253A52%253A15+%252B0300
so you can werifi in action if link is not expired
I'm working on a fairly traditional forgot password email - I want to email the user a password change token embedded in a link that they can click on in order to change their password. I'm emailing via the traditional ActionMailer.
If I use a normal link_to tag
<%= link_to "click here", :controller => foo, :action => 'bar', :token => token %>
I get a relative link - rather useless from an email.
If I add in
:only_path => false, then it errors saying I need to set default_url_options[:host]. The ActionController docs imply that you do that by overriding the #default_url_options methods in your controller. Surely there's a configuration option to tell Rails what it's hostname is without adding my own config file, parsing it, etc?
default_url_options is available from config.action_mailer and should be set in your environment's configuration file.
For example, in config/environments/production.rb:
config.action_mailer.default_url_options = {
:host => 'www.yourdomain.com'
}
For local testing, modify config/environments/development.rb:
config.action_mailer.default_url_options = {
:host => '127.0.0.1',
:port => 3000
}
Then, assuming you have a named route called forgot_password_login, you can generate the login link URL in your mailer using something like this:
forgot_password_login_url(:token => 'a7s8q15sk2...')
You probably want to set :protocol => 'https' as well, btw.
config.action_mailer.default_url_options = {
:host => "portal.example.com",
:protocol => 'https'
}
There is another alternative, as described in http://pivotallabs.com/how-i-leaned-to-stop-hating-and-love-action-mailer/
This solution has the advantage that it doesn't require any configuration (so less of a hassle), and works fine as long as you send emails from within controllers.
But if you plan on sending email without going through a controller (e.g. from command line or in response to another email), you need the static configuration.
Setting default_url_options directly is deprecated in Rails 3.1. Use url_for instead.
Add parameter :protocol to override default value (http), :protocol => 'https://'. This will create url starting with "https://..." instead of default "http://"
Interestingly, I had the same issue as you did, but in unit tests (while following Michael Hartl's railstutorial). I had this line in my test.rb file, but that didn't help:
config.action_mailer.default_url_options = { host: 'example.com', protocol: 'http' }
I've also added another line like this to test.rb, and surprisingly this solved the issue
default_url_options = { host: 'example.com', protocol: 'http' }
Setting default_url_options directly is deprecated in Rails 3.1
Use the url_for helper to create it:
<%= link_to "click here", url_for(:controller => foo, :action => 'bar', :token => token, :host => 'www.yourdomain.com') %>
Can you just do
<%="click here", :controller => foo, :action => 'bar', :token => token, :host=>request.host -%>
