Apply a single variable to all fields

If you're someone who values efficiency in backend development, Xano has a nifty feature that will become your new best friend. Say goodbye to the tedious task of manually mapping variables to individual input fields, and embrace the power of Xano's variable mapping tool. In this blog post, we'll guide you through the steps to leverage this time-saving feature and unlock a smoother development workflow.

Step 1: Identify the Function and Variable

Let's start by locating the function where you want to apply the variable mapping. For this example, we'll use the "add record" function, where all the fields need to be mapped to a single variable called "data" from the "get all input" function.

Step 2: Access the Variable Mapping Tool

Once you've opened the "add record" function, you'll notice input fields corresponding to the fields in your database table. Instead of manually typing the variable name and using dot notation for each field, look for the magic wand icon next to the input fields. This icon holds the key to unlocking the variable mapping feature.

Step 3: Apply the Variable to All Inputs

Click on the magic wand icon, and a pop-up window will appear with the option "Apply a single variable to the inputs." Select this option, and then choose the variable you want to apply from the dropdown menu. In our case, we'll select the "data" variable.

Xano will automatically map the selected variable to all the input fields, saving you from the hassle of repetitive manual input. However, there's a crucial step to ensure everything works smoothly.

Step 4: Match the Field Names

For the variable mapping to work correctly, the field names in your database table must match the path names in the variable you're applying. Xano will automatically find the corresponding field names and use them as the path names for the variable.

Step 5: Set Default Values (Optional)

The variable mapping tool also provides an option to set flexible default values. If you anticipate scenarios where the incoming variable might not have a value for certain fields, you can define default values to handle those cases.

When selecting the "Apply a single variable to the inputs" option, you'll see an additional checkbox labeled "Flexible default values." Check this box, and you'll be prompted to enter a default value (e.g., null, a specific value, etc.). Xano will use this default value for any fields that don't have a corresponding value in the incoming variable.

With Xano's variable mapping feature, you can streamline your backend development process, saving valuable time and effort. Whether you're a no-code enthusiast, a citizen developer, a traditional developer, or part of a startup or small business, this handy tool will undoubtedly become a go-to resource in your backend development arsenal.
