How to remove all the respond_to code ?

Answer 1

Use respond_with to make your controllers cleaner. This apidoc and
this screencast will answer all your related questions.
Your controller methods will be as clean as this:
def update
#idea.update(idea_params)
respond_with #idea, notice: 'Idea was successfully updated.'
end
To apply that to default scaffold controller template, just copy the template content from github and put it into RAILS_ROOT/lib/templates/rails/scaffold_controller/controller.rb. Then apply the respond_with approach there.

Answer 2

Just do so like this.
For e.g.
respond_to do |format|
if #idea.save
format.html { redirect_to #idea, notice: 'Idea was successfully created.' }
format.json { render action: 'show', status: :created, location: #idea }
else
format.html { render action: 'new' }
format.json { render json: #idea.errors, status: :unprocessable_entity }
end
end
can be replaced with
if #idea.save
redirect_to #idea, notice: 'Idea was successfully created.'
else
render 'new
end
