devise Getting started with devise
Remarks
This section provides an overview of what devise is, and why a developer might want to use it.
It should also mention any large subjects within devise, and link out to the related topics. Since the Documentation for devise is new, you may need to create initial versions of those related topics.
Installation or Setup
1. Add Devise Gem
Open up your Gemfile and add this line
gem 'devise'
Then run;
bundle install
2. Set up devise in your app
Run the following command in the terminal
rails g devise:install
3. Configure Devise
Ensure you have defined default url options in your environments files. Open up config/environments/development.rb and add this line:
config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
Open up app/views/layouts/application.html.erb and add:
<% if notice %>
<p class="alert alert-success"><%= notice %></p>
<% end %>
<% if alert %>
<p class="alert alert-danger"><%= alert %></p>
<% end %>
right above
<%= yield %>
Open up app/views/ideas/show.html.erb and remove the line that says:
<p id="notice"><%= notice %></p>
- Do the same for app/views/comments/show.html.erb. These lines are not necessary as we’ve put the notice in the app/views/layouts/application.html.erb file.
4. Setup the User model
We’ll use a bundled generator script to create the User model.
rails g devise user
rake db:migrate
Coach: Explain what user model has been generated. What are the fields?
5. Create your first user
Now that you have set everything up you can create your first user. Devise creates all the code and routes required to create accounts, log in, log out, etc.
Make sure your rails server is running, open http://localhost:3000/users/sign_up and create your user account.
