I apologize for the embarrassingly simplistic nature of this question,
but I’m new to Ruby/Rails.
From within a html.erb file, what is the syntax for assigning a value
to a parameter? For example, when a specific form is used, the
following attribute (make_this_true) should always be 1
<% form_for(@foo) do |f| %>
<%= f.error_messages %>
…
<%= f.label :make_this_true %>
<% foo.make_this_true = 1 %>
but I don’t have to tell the readers of this group that the above code
is garbage.
- is there an easy way to set this attribute? If so, what is the
syntax?
- My first attempt at solving this problem involved using a check box
or a radio button that defaulted to “true” but this turned out to be
non-intuitive as well. I then realized that the user should not need
to interact with this variable here.
- Perhaps making the default value of this variable true in the
database schema? Any tips on that route?
Sorry for the long-windedness and simplistic nature of this question.

I’d do it with a hidden field, others may be able to recommend something
else though.

I’d go for a hidden field too.

In your controller:
new:
@foo = Foo.new(:make_this_true => true)
new.html.erb
<%= f.hidden :make_this_true %>
or, create:
@foo = Foo.new(params[:foo]) {|f| f.make_this_true = true }
Having a default in the DB schema is likely a good idea,too. If this
is actually a boolean, having :default=>true,:null=>false keeps you
from dealing with NULL values in the database.
