I've read this, but I'm new to RoR so I'm having a little trouble understanding it. I'm using a form to create a new request record, and all of the variables that I need to send exist already. Here is the data I need to send (this is in a do loop):
:user_id => w[:requesteeID]
:requesteeName => current_user.name
:requesteeEmail => current_user.email
:info => e
Here's my form, which works so far, but only send NULL values for everything:
<% form_for(:request, :url => requests_path) do |f| %>
<div class="actions">
<%= f.submit e %>
</div>
<% end %>
How do I use hidden_fields to send the data I already have? Thanks for reading.
Ref hidden_field or hidden_field_tag
<% form_for(:request, :url => requests_path) do |f| %>
<div class="actions">
<%= f.hidden_field :some_column %>
<%= hidden_field_tag 'selected', 'none' %>
<%= f.submit e %>
</div>
<% end %>
then in controller
params[:selected]="none"
params[:request][:some_column] = request.some_column
Note when you used
<%= f.hidden_field :some_column %>
it change to html
<input type="hidden" id="request_some_column" name="request[some_column]" value="#{@request.some_column}" />
and when you used
<%= hidden_field_tag 'selected', 'none' %>
it change to html
<input id="selected" name="selected" type="hidden" value="none"/>
