Render template to string ruby

Modify above code like:. The controller can also able to redirect to some other action. The request comes to the controller. But if they are not logged in then redirect to any other section of our code.

The redirect is a way to indicate browser to the new location to send request. And a new request is being placed in the browser for the new url sent by the server. To Redirect user when the user tries to access hello method of demo controller. We put a redirect to index method when a user requests hello method. Try it yourself. While the 4th line only executes ruby code but no output will be generated.

And the 5th line uses x variable to output with string. And then loop is being executed with multiple ruby code blocks. In order to pass data to View, we have to create instance variable in the controller.

Open demo controller and modify code as follows:. Now we can use it to view. Open hello. Instead of the static loop now we have changed loop into dynamic which cycle through a loop and passes 1 by 1 element of the array into d. When all elements are used loop will be finished automatically.

This is much better and cleaner solution without any additional setup required! If you don't want to escape html, just call. Btw, just in case you are trying it - you can't render a partial in a controller - you can only render partials in views Edit: yeah your problem is you trying to render a partial in the controller action.

Thank you for your reply. I've add the controller to my post. I think it's caused by the erb rendering thing. This app sends orders to restaurants, it's difficult for them to check emails, so fax The string of html is pretty long, and including variables. I wish I could write it into a seperate erb file Try this def create order. Thank you for your replay.
