Form_for problem after upgrading

rubyonrails-talk
1

I am upgrading to rails 3 and afer diong so, none of my form_for are working. (I can not actually say not all of them are working but the few that i have tried are not). The page loads fine but the form is not output. This is after making the the change from <% to <%=. A sample form is below.

<%= form_for @user_session, :url => user_session_path do |f| %>   Email <br/>   <%= text_field_tag :login %><br/>   Password <br/>   <%= f.password_field :password %><br/>   Remember Me   <%= f.check_box :remember_me %> <br/>   <%= f.submit "Login" %> <% end %>

<%= form_for @user_session, :url => user_session_path do |f| %>   Email <br/>   <%= text_field_tag :login %><br/>   Password <br/>   <%= f.password_field :password %><br/>   Remember Me   <%= f.check_box :remember_me %> <br/>   <%= f.submit "Login" %> <% end %>

replace <%= text_field_tag :login %><br/> with <%= f.text_field :login %>

what is the output in the log?

<%= form_for @user_session, :url => user_session_path do |f| %> <p><%= f.label( :login , "Email ") %><br /> <%= f.text_field :login %></p> <p><%= f.label :password %><br /> <%= f.password_field :password %></p> <p><%= f.label :remember_me%><br /> <%= f.text_field :remember_me%></p> <p><%= f.submit "Login" %></p> <% end %>

Hi,

In that case you need to use 'dynamic-form' plugin for rails3

This plugin can auto modify you syntax at runtime.

Good Luck :wink: -Ganesh K

hmmm... well i installed that plugin however i am still having no luck.

form_tag seems to work properly.

my dev log does not give me any errors, just some depreciation warning unrelated to this problem.

any ideas?

Any ideas? Below is the dev log when i load that page. none of the below seems to be related.

even when i add random text with the form liek "Email" as below is not even outputted. it is as if the whole blcok is being ignored...

<%= form_for @user_session, :url => user_session_path do |f| %>         Email <br/>   <%= text_field_tag :login %><br/>   Password <br/>   <%= f.password_field :password %><br/>   Remember Me   <%= f.check_box :remember_me %> <br/>   <%= f.submit "Login" %> <% end %>

solution found. there is apparently a conflict with an older version of haml.

https://rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/5493

install haml 3.0.18 or higher to resolve.
