form_tag and a very simple form

Hello all

I'm building a form that is not based on a model. The action I want
to happen when I click submit is defined in my controller.

Here's the form code in the html.erb

<% form_tag '/gevents/dotheformstuff/' do -%>
<div>Username: <%= text_field_tag("username", "", :size => 40) %></

<div>Password: <%= password_field_tag("password", "", :size => 40) %></

<div><%= submit_tag 'Find' %></div>
<% end -%>

Is this the best way to proceed, with now me editing my routes file so
that /gevents/dotheformstuff/ get's thrown to a controller and action
of my choosing?

I've been reading about using the form_tag like this

<%= form_tag :action => "create" %>

But my rails is not liking the end_form_tag when I use that. This
might be pre rails 2 code, can someone verify?

It does seem a lot neater to describe the action in the form_tag
rather than edit routes.rb though.

Also, when I do send the data back to the controller, how do I go
about extracting it? I'm not sure of the syntax needed.

Any advice, greatly appreciated.

That is indeed pre rails 2 (and deprecated in 1.2)

You're conflating to things. What's deprecated is end_form_tag (ie the
non block form of form_tag). You can of course do
<% form_tag :action => "create" do %>
...
<% end %>

It just in your params hash.

Ack, brain still asleep. That should of course say "conflating two
things"

Frederick, thanks for clearing that up.

It's a bit tricky out there at them moment with so many sites showing
help on rails prior to 2.

We'll get there though

:slight_smile:

Thanks again.

Frederick, I'm having a doozy of a time finding out how to create a
parameters hash out of those two fields when I'm using form_tag

You couldn't point me in the right direction anyone?

Rails 2, Creating a Parameters Hash in a form using form_tag.

Can't find anything easy enough for my diseased brain

I'm not sure I understand the problem. You will get the params hash in your controller without having to do anything.

I'm not sure how to access the params hash in the controller as I
don't know how to refer to it.

Here's the form in the view

<% form_tag :action => "getcals" -%>

<div>Username: <%= text_field_tag("username", "", :size => 40) %></

<div>Password: <%= password_field_tag("password", "", :size => 40) %></

<div><%= submit_tag 'getcals' %></div>
<% end -%>

How would I refer to the params hash of that in the controller
getcals?

Thanks for helping Frederick

woops, missed a do

<% form_tag :action => "getcals" do -%>

<div>Username: <%= text_field_tag("username", "", :size => 40) %></

<div>Password: <%= password_field_tag("password", "", :size => 40) %></

<div><%= submit_tag 'getcals' %></div>
<% end -%>

Frederick, I promise you it's me who is confused, not yourself.

Thanks mate, that's worked a treat.

I can now pass these variables back and forth and do what I want.

Thanks again.
