I have a following snippt to make a form.
<% form_for :post, @post, :url => { :action => "create" } do |f| -%>
<%- end ->
What does ":post" and "@post" do respectively?
If my understanding is correct, @post is there because I set "@post = Post.new" in the action. But I don't know what ":post " is for.
Tek
:post is the parameter that will be symbolic to f
another form format is
<% form_tag :action => "create" do %>
<%= text_field "post", "name" %> OR <%= text_field :post, "name" %>
<% end %> <% end_tag %>
BUT HERE
<% form_for :post, @post, :url => { :action => "create" } do |f| -%>
<%- end ->
<%= f.text_field "name" %>
in your controller the input parameter will be params[:posts] and its hash. params[:posts]["name"] params[:posts]["id"]
Like that.
