My error messages are not showing automatically, so I decided to use flash as a workaround. This is what I'm doing
Controller:
flash[:notice] = @post.errors.full_messages
View:
<%= flash[:notice] %>
Then, I get this ugly error message on my view.
["Content can't be blank", "Content is too short (minimum is 10 characters)"]
But at least, the user successfully gets the error message. Now I need to customize the error message and make it look a little bit more pretty. I guess I could parse each error sentence into some local variables and show them (is there a more sophisticated way?). However, I don't know how to customize the error message. For example, "Content can't be blank" should be changed to "You left the content blank". Where can I fix this?
What happens is that when @post contains some validation errors doing @post.errors.full_messages
returns an array of errors that happened during validation.
To display them nicely you might want to do something like
<%- flash[:notice].each do |error| %>
<%= error %>
<% end %>
EDIT Whoops I misread the question.
These errors are validation errors in your model where you have the validations like
validates
you can pass custom messages like so
validates :content, :presence => { :message => "You left the content blank" }
