Hi,  
Friends, I am working on ruby on rails,

1. I have created a login form

\<%=flash[:notice].to\_s%\> 

```
<legend>
  Please Log In
</legend>
<% form_tag do %>
<p>
  <label for="name">Name:</label><br/><br/><br/>
  <%= text_field_tag :name, params[:name]%>
</p>
<p>
  <label for="password">Password:</label><br/><br/>
  <%= password_field_tag :password, params[:password]%>
</p>
<p>
  <%= submit_tag "login"%>

</p>
<%end%>

```

\<%#= button\_to “Back”, :controller=\>:main, :action=\>:unreg\_disp\_data%\>

```
</fieldset>

```

1. Then rendered this form in view using render\_component but after  
rendering this way i was unable to get the passed arguments

3)If i am creating a link instead of render\_component e.g.

\<%= link\_to\_remote “Sign In”,{  
:update=\>“account”,:url =\> {:controller =\> :account,:action =\> :login}  
}-%\>

it works fine

Can anyone suggest a solution for this, I will be thankful for the same

Regards,  
Kiran P.

Is there any particular reason you are using render\_component?  
render\_component is mostly dead (IIRC it’s because components are big  
and heavy, because they are actually separate controller instances  
under the hood (which is probably why accessing params from the  
‘other’ instance of ActionController doesn’t work)

components are dead. don’t use components. I’ve never used components  
(because of the former) and so I’m not well aquaintent with their  
intricacies. You probably could get something together using  
the :locals option of render, but like I said, components are dead.  
Use a partial.

Thank you very much… 🙂 it really works. I have used partials to do  
the same thing along with passing the arguments…

I have one more problem regarding using ajax, I want to show and hide  
div on mouseover and mouseout events of another div, but it doesn’t  
work, it continuously does same thing I am expecting some code or
