While working with devise gem, I need to show the failure messages like “Invalid username / password” (As shown in the below image) when user enters a wrong username/password.

Tip : Making email as optional (not mandatory) field in devise in Rails
This situation arises, when we need to login through a different unique key other than email and wanted email to be optional in the entry form.
Prerequisites
Make sure in config/initializers/devise.rb to set the config.authentication_keys to some other field (not email, which is default) in devise.rb
|
1 2 3 4 |
# config.authentication_keys = [:email] config.authentication_keys = [:user_name] |
Now, let’s do
In the model rb (user.rb in my case) file,

def email_required? false end def email_changed? false end |

Multiple Submit buttons in a single view in Rails
While working in an assignment, I have to dealt with view where I have to re-send the verification code form the same view in which I have to accept the verification code.
As shown in the image, “Confirm” and “Resend code” both are 2 submit buttons. I need to resend another code from the same page without redirecting.
How I made it work ??
View part
Added both the submit buttons
|
1 2 3 4 |
<%= f.submit "Resend Code", :name=>"resend_code" %> <%= f.submit "Confirm" %> |
Controller part
Handled the post action part
|
1 2 3 4 5 6 7 8 |
if params[:resend_code] # code to handle code generation and resend # redirect to the same page else # code to handle confirm functionality end |

Fixing ExecJS::ProgramError in page
How I got the issue
Created a new project in rails
$ rails new StaticPageDemo
Added static_page controller to it with home action
$ rails generate controller static_page home
Ran the server
$ rails server
Got this error while tried to access the page in http://localhost:3000/static_page/home
Solution
After some search in Google, I got a solution from this link, which helped me fixing the issue. I also learned, It is an issue with the windows. The application parameter works on the web server.
Opened the application.html.erb in app/views/layouts folder of StaticPageDemo project. Replaced application with default.
