I was using rails to create a sqlite table in my application, I tried an example from a tutorial which I typed the command:
rails generate scaffold Product \
title:string description:text image_url:string price:decimal
It worked and generated a table, however, when I ran
rake db:migrate
It came up some problem:
SyntaxError in ProductsController#index
products_controller.rb:72: syntax error, unexpected ':', expecting ')' ...rams.require(:product).permit(: title, :description, :image_... ... ^
So I looked into the table and found that there's an extra space between title and string, it's like this:
title : string
description :text
image_url :string
price :decimal
Then I changed it and the corresponding controller. The controller was like this before I changed it, also an extra space here:
def product_params
params.require(:product).permit(: title, :description, :image_url, :price)
end
After that, whenever I tried to create a table, the same problem came again and again. The first attribute always has an extra space while the following attributes don't. So anyone knows what's the problem? Thank you so much! :)
