August 8, 2016 No comments Article

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.

I have added the flash massage to show the error as shown in below code in app/view/devise/sessions/new


<%= flash[:alert]%>

<%= flash[:alert]%>

Hope this helps

Tip : Making email as optional (not mandatory) field in devise in Rails

August 4, 2016 No comments Article

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


# config.authentication_keys = [:email]
config.authentication_keys = [:user_name]

# 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

def email_required?

false

end

def email_changed?

false

end
