Rails 5.1 Mailer错误-模板中的帐户激活参数

Question

I'm following Mike Hartl's Rails tutorial & ran into an issue when creating email templates. (Please note the tutorial is based on Rails 5.0.1, while I'm plowing ahead with Rails 5.1.1.)

The tutorial uses :activation_token & :activation_digest attributes to handle the security risks of signup URLs, and a :create_activation_digest hook to set their values before creating the User model.

Here's the mailer view template:

<%= link_to "Activate", edit_account_activation_url(@user.activation_token, email: @user.email) %>

The issue appears to be telling Mailer to use the value of :activation_token in the :id field of the route. (A URL definition error)

Here's the route definition, from rails routes :

edit_account_activation GET    /account_activations/:id/edit(.:format) account_activations#edit

The error feedback:

No route matches {:action=>"edit", :controller=>"account_activations", :email=>"test7@example.com", :format=>nil, :id=>nil}, possible unmatched constraints: [:id]

I've tried hard-coding id: @user.activation_token in the mailer template, to no avail.

This seems like a easy one, but I'm stumped and a little worried that I'm overlooking something hidden in the transition from Rails 5.0.x to 5.1.x. Any ideas?

Answer 1

You are getting this error because in your config/routes.rb file, you GET /account_activations/:id/edit . That makes it necessary to send an ID which you don't want/need to do. Now I know that Rails Tutorial uses :id for token. But you're not defining id: in your link. So either you need to change the route, or change the link.

<%= link_to "Activate", edit_account_activation_url(id: @user.activation_token, email: @user.email) %>

Notice I define id: . Normally outside this tutorial though, you should consider changing your route to GET /account_activations/edit/:token and then look up the user by token.

Thanks all, But the error was related to how I defined the :activation_token hook in the User model. All tests now pass.
