Dear sirs,
I dont’t think the addition of :message => “can’t be blank” does make a
difference.\
Validations have their own strings already packed, in en.yml in the
active_model gem. In the console (rails c) you can try it out (assuming
your model is named ‘Person’):
p=Person.new
p.valid?
p.errors
or p.errors[:name]
You will see that it will show a message “can’t be blank” also when you
don’t’ specify :message in the validation!
So, these messages are already generated, now you want to show them,
look
here:
http://guides.rubyonrails.org/active_record_validations_callbacks.html#displaying-validation-errors-in-the-view
for documentation.
Also, have a look at validation_hints gem
(GitHub - acesuares/validation_hints: Hints for validation) which helps you display
helpful context sensitive messages for form fields</shameless plug>!

Hi manoj,
I am replying to a message that you posted on the ruby-forum but didn’t
show up in google groups.
Anyway, did you put
gem “dynamic_form”
in your Gemfile?
And then after that, run ‘bundle install’ ?
Please do so and try again.
cheers

Dear ace,
as per you have told, i wrote <%= f.error_messges %> in my
view page to display error when leaving name as empty , but right now am
getting like “undefined error_messages”, please help me to solve this
problem .

manoj
Manoj,
Open up the console (rails c), and then create a new User (or whatever
model you want) like this:
u = User.new
Check if this user is valid:
u.valid?
This should result in false! if NOT, then you dont’ have any errors.
Then
you have to look at you validation lines in the model…
If it is false then try:
u.errors
u.errors.full_messages
this SHOULD give you an array of error messages. If not, there’s
something
wrong.
Now go back to your view and insert
ERRORS: <%= @object.errors.full_messages %> !!! %>
into your view. Of course the @object must match the one you are making
the
form for.
Tell me what you see then.
Cheers

view page,where only empty array is displayed, i have no idea what to
do, its been more than 4 days i have stucked please help me out,

try to write this
<% if @variable_name.errors.any? %>
<%= pluralize(@ variable_name .errors.count, “error”) %>
prohibited this user from being saved:
<ul>
<% @ variable_name .errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
