We previously explored how a list of tasks is presented using the following controller code:
In the corresponding index.html.erb file, we employ the @tasks variable to iterate through each task and display its title:
In this context, variables prefixed with @ in Rails controllers are referred to as instance variables. These instance variables possess the unique property of being automatically available in our Rails views.
Hence, in the index.html.erb file, we can directly access and utilize the @tasks instance variable.
It's important to note that any instance variable created in a controller becomes accessible in the corresponding view file. Conversely, variables that are not defined as instance variables in the controller will not be accessible in the views.
There is nothing to commit in this chapter. This chapter primarily focused on elucidating the concept of instance variables in Rails, highlighting their automatic availability in views.
