i''m trying to create a form which has dropdown menus for certain items
and text boxes for others. i have a feeling i''m trying way too hard to
make this happen. i have a method which writes strings of the proper
tags, which are then brought to life by eval() in the view. the strings
are correct, but something about how eval parses the string only allows
for one argument, even if i parenthesize them. i feel like i should not
have to be using eval at all.
any guidance is appreciated.
THE CONTROLLER:
def run
@script = @@scriptinfo.getTest(params[:choose][:scriptname])
@parameterforms = @script.parameters.collect { |param|
chooseForm(param) }
end
def chooseForm(parameter)
if parameter.length <= 1
"f.text_field :#{parameter.name}"
else
"f.select :#{parameter.name}, #{parameter.values.join('',
'')}] "
end
end
THE RUN VIEW:
<% form_for :scriptparams, :url => {:action => "results"} do
|f| %>
<% @script.parameters.each_index do |index| %>
<%= @script.parameters[index].name %>
<%= eval(@parameterforms[index]) %><br />
<% end %>
<% end %>
