form_for NoMethod Error

Question

I keep getting a NoMethodError for my form_for

This is in my _form.html.erb

<%= form_for @booking do |f| %>
  <%= f.label :content %>
  <%= f.text_area :content, rows: 6 %>
  <%f.submit 'Save' %>

and in new.html.erb

<h1> New Booking </h1>  
<%= render 'form' %>

and the end result: NoMethodError in Bookings#new appears.

(PS this question is a bit off-topic but how would I go in making a form input for selecting a TO and FROM date (in order of month:day:year)?

Answer 1

It appears you don't haven't migrated your model, so it only has an id and timestamps. Just create a new migration (or edit the existing if you don't mind resetting the db, but it isn't a good practice).

Run in terminal:

rails generate migration AddContentToBookings content:text

and then

rake db:migrate
