Search with act_as_taggable_on

I am trying to search by model for all records with a specific tag.

An example of the output we are trying to find:

ruby-1.9.2-p0 :1 > Question.last.tags => [#<ActsAsTaggableOn::Tag id: 2, name: "preferences">, #<ActsAsTaggableOn::Tag id: 13, name: "travel">]

So, Question has tags , for example, preferences and travel. I tried:

 @tags = @questions.where("tags LIKE ?", "%#{params[:tags]}%") => [] @tags = @questions.where("tag LIKE ?", "%#{params[:tags]}%") => [] @tags = @questions.where("tag_list LIKE ?", "%#{params[:tags]}%") => BadFieldError: Unknown column 'tag_list'

How to return the top record if params[:tags] is, for example, "refere" or "ences"?

Question Model

 class Question < ActiveRecord::Base has_many ... acts_as_taggable_on :tags end

Second attempt

I just created a custom controller action to try to modify the request according to the @Nash suggestion. How can I fix it?

 def autocomplete_question_tags @tags = Question.tagged_with("%#{params[:term]}", :any => true) respond_to do |format| format.json end end

When entering "travel" in the form:

You can let your parameter search for any part of the tag instead.

 Question.tagged_with("%#{params[:tags]}%", :any => true)

The accepted answer no longer works.

Current solution:

 Question.tagged_with(params[:tags], wild: true, any: true)
