Hi -
I''m trying to understand the help for this:
http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M000940
it says:
select(object, method, choices, options = {}, html_options = {})
questions-
1) what is ''object'' ? Is this an ActiveRecord object?
2) what is method?
3) do i assume that my form object created from form_for calls select
directly?
4) what is the form of object- is it "user", @user, user, or :user ?
Please explain why, this is terribly confusing for a newbie.
So, if I have a view:
<% content_for(:page) do %>
<h1>New user</h1>
<% form_for :user, @user, :url => { :action => "create" } do
|form|
%> #NOTE I''M TRYING TO USE FORM_FOR
<%= render :partial => ''form'', :locals => { :form
=> form, :genders =>
@genders, :user=>@user} %> #SEND THE FORM INSTANCE DOWN TO PARTIAL
<%= submit_tag "Create" %>
<%end%>
<%end%>
Notice I''m attempting to send the current user to the partial,
I''m not
sure if I''m doing this right. Also, my controller created a User
instance (@user) which I''m sending to the partial.
and the partial:
<p>
<label>
Last Name<br/>
<%= form.text_field :lastname %>
</label>
</p>
...
<p>
<label>
Gender<br/>
<%= form.select(''user'', "gender",
{"Male" => 1, "Female" =>2 })%>
#THIS DOESN''T WORK
</label>
</p>
Note, there is no gender table, just 2 choices. User has a gender
field which is an integer.
So all I''m trying to do is let the client choose a gender from a
select box. Please tell me what I''m doing wrong and if possible,
answer my questions above.
Thanks,
Dino

This could be a db column or a computed property. form_for makes things a bit easier: when using form_for you don''t need to specify object (since that is setup in the call to form_for) ie you can do form.select(:gender, ...) (in the same way that you can do form.text_field :lastname) Fred> > So, if I have a view: > > <% content_for(:page) do %> > <h1>New user</h1> > <% form_for :user, @user, :url => { :action => "create" } do |form| > %> #NOTE I''M TRYING TO USE FORM_FOR > <%= render :partial => ''form'', :locals => { :form => form, :genders => > @genders, :user=>@user} %> #SEND THE FORM INSTANCE DOWN TO PARTIAL > <%= submit_tag "Create" %> > <%end%> > <%end%> > > Notice I''m attempting to send the current user to the partial, I''m not > sure if I''m doing this right.
