Question

I am trying to put a search (microposts) function into my app. All of the ways to do it involve giving the definition

@microposts=Micropost.search(params[:search])

or something like that. you always have to define @microposts in the microposts_controller.rb

The problem is that I already have

def home
     @microposts=Micropost.all
end

because initially the home page is just a list of all microposts. How can I change the definition once the user uses the search function. Is that the only way? Do I need an if then statement.

like if they press search @microposts=Micropost.search(params[:search]) else @microposts=Micropost.all? how can I do that?

Answer 1

when the page is initially loaded, i guess the params[:search] was not present. so you can try:

if params[:search].present?
  @microposts=Micropost.search(params[:search])
else 
  @microposts=Micropost.all
