I am trying to maintain a pretty URL when having a user messaging with failed validation.
I have a routes file that looks like the following:
# For logged users convenience
# example.com/messages
# instead of: example.com/users/:user_id/messages
map.resources :messages
# For everyone else
map.resources :users do |p|
p.resources :messages
end
So new_user_message_path(@user) returns:
/users/:user_id/messages/new
The message's new.erb view produces the correct code:
<form action="/users/:user_id/messages" .........
When validation fails it shows the form errors but renders the wrong action:
<form action="/messages" .........
So the second time the user submits the form the "create" method can't find the user_开发者_运维问答id
Here are my controller methods:
def new
@user = User.find(params[:user_id])
@message = @user.messages.build
end
def create
@user = User.find(params[:user_id])
@message = @user.messages.new(params[:message])
if @message.save
flash[:notice] = 'Message saved'
redirect_to user_url(@user)
else
render :action => "new" # Here is the problem I guess
end
end
And my form view:
<% form_for [@user, @message] do |f| %>
<%= f.error_messages %>
Name:<%= f.text_field :name %>
Email:<%= f.text_field :email %>
Message:<%= f.text_area :body, :rows => 3 %>
<%= f.submit 'Send' %>
<% end %>
try
<% form_for [:user, @message] do |f| %>
