Ruby on rails - How to assign a variable in an If else statment check

In Ruby on Rails, or Ruby in general, you can assign a variable within an if-else statement. The typical structure for doing this looks like the following:

variable = if condition # value to assign if condition is true else # value to assign if condition is false end

Here's a concrete example:

user_role = if user.admin? "Admin" else "Standard User" end

In this example, user_role is assigned the value "Admin" if user.admin? returns true, otherwise it is assigned "Standard User".

Another way to write this in a more concise manner is by using the ternary operator:

user_role = user.admin? ? "Admin" : "Standard User"

This does exactly the same thing but in a more compact form. The ternary operator is a common idiom in many programming languages for simple if-else conditions.

Both of these are standard Ruby syntax and are commonly used in Ruby on Rails applications. Remember to choose the one that best fits your code style and readability preferences.

  1. Assign Variable in If-Else Condition:

    if condition variable = value_if_true else variable = value_if_false end

  2. Assign Value to a Variable Based on If-Else in Rails:

    variable = if condition value_if_true else value_if_false end

  3. Conditional Variable Assignment in Ruby on Rails:

    variable = condition ? value_if_true : value_if_false

  4. Set Variable Inside If-Else Block in Rails:

    if condition variable = value_if_true else variable = value_if_false end

  5. Ruby on Rails If Else Statement Assign Variable:

    variable = if condition value_if_true else value_if_false end

  6. Conditional Assignment in Rails Controller:

    @variable = condition ? value_if_true : value_if_false

  7. Variable Assignment Based on Condition in Ruby on Rails:

    variable = if condition value_if_true else value_if_false end

  8. If-Else Block Variable Assignment in Rails View:

    <% if condition %> <% variable = value_if_true %> <% else %> <% variable = value_if_false %> <% end %>

  9. Ruby on Rails Conditional Variable Initialization:

    variable ||= condition ? value_if_true : value_if_false

  10. Dynamic Variable Assignment in If-Else Statement Rails:

    variable = if dynamic_condition dynamic_value_if_true else dynamic_value_if_false end
