Hi,
I''m using acts_as_taggable. I have a form that asks for a question and
a tag
for that question, something like:
<% form_tag -%>
<%= text_area("question", "question_text") %>
<%= text_field("tag", "name") %>
<%= submit_tag %>
<% end_form_tag %>
The question is one model. Tag is another.
My problem is that I can''t figure out how to validate that the user
inputs a
tag. He must input both a question and a tag.
My controller method looks something like:
def add_question
if request.get?
@question = Question.new
@tag = Tag.new #needed this so my errors_messages_for :tag will not
cause error
else
@question = Question.new(params[:question])
if @question.save
@question.tag(@params[:tag][:name])
flash[:notice] = "Thank you. Your question has been
added."
redirect_to edit_url(@question.id)
end
end
end
I tried nesting a transaction for both question and tag, but that
didn''t
work. I tried various ways of passing the tag names into the
@question.tagmethod.
My validations include:
Class Question < ActiveRecord Base
validates_presence_of :question_text, :message=>"must not be
blank."
validates_length_of :question_text, :maximum=>150, :message=>"must
be less
than 150 characters."
end
Class Tag < ActiveRecord Base
validates_presence_of :name
validates_length_of :name, :in => 1..20, :too_long => "Tag name
too long
- max 20 characters", :too_short => "Tag must have a name"
end
Suggestions are appreciated.
