ComfyUI Node: D2 Filename Template

D2 Filename Template:

The D2 Filename Template node is designed to facilitate the dynamic generation of filenames based on customizable templates. This node is particularly useful for AI artists who need to organize and manage their files systematically. By using placeholders within a template string, you can automatically insert various types of data, such as the current date and time, specific node parameters, or custom arguments, into your filenames. This capability not only enhances file organization but also streamlines workflows by reducing the need for manual file naming. The node's flexibility allows you to tailor filenames to suit your specific project requirements, ensuring consistency and clarity in your file management practices.

D2 Filename Template Input Parameters:

format

The format parameter is a string that defines the template for generating filenames. It supports placeholders for dynamic content insertion, such as %date:{yyyy/MM/dd/hh/mm/ss}% for the current date and time, %node:{id}.{key}% for node-specific parameters, and %arg_1%, %arg_2%, %arg_3% for custom arguments. This parameter is required and allows you to create complex and meaningful filenames by combining static text with dynamic data. There are no predefined minimum or maximum values, but the string should be structured correctly to ensure proper filename generation.

arg_1

The arg_1 parameter is an optional input that can be used to pass any type of data into the template. It is particularly useful when you want to include specific information in the filename that is not covered by the default placeholders. This parameter is flexible and can accept various data types, allowing you to customize the filename further based on your needs.

arg_2

Similar to arg_1, the arg_2 parameter is an optional input that allows you to pass additional data into the template. It provides another layer of customization for your filenames, enabling you to include more specific details or metadata that are relevant to your project.

arg_3

The arg_3 parameter functions like arg_1 and arg_2, offering yet another optional input for passing data into the template. This parameter enhances the node's flexibility by allowing you to incorporate even more custom information into your filenames, ensuring they are as descriptive and informative as possible.

D2 Filename Template Output Parameters:

STRING

The output parameter, STRING, represents the generated filename based on the provided template and input parameters. This output is crucial as it reflects the successful application of the template logic, resulting in a filename that incorporates all specified dynamic elements. The generated filename can then be used for saving files in a structured and organized manner, aiding in efficient file management and retrieval.

D2 Filename Template Usage Tips:

• Use descriptive placeholders in the format parameter to ensure filenames are informative and easy to understand.
• Combine date and time placeholders with custom arguments to create unique filenames that reflect both the creation time and specific project details.
• Test different template configurations to find the most effective structure for your file organization needs.

D2 Filename Template Common Errors and Solutions:

Invalid placeholder format

• Explanation: This error occurs when the template string contains placeholders that are not correctly formatted or recognized by the node.
• Solution: Ensure all placeholders in the format string are correctly formatted according to the node's specifications, such as %date:{yyyy/MM/dd/hh/mm/ss}% for date and time.

Missing required format parameter

• Explanation: The node requires a format string to generate filenames, and this error indicates that it was not provided.
• Solution: Provide a valid format string that includes the necessary placeholders for dynamic content insertion.

Unsupported data type in arg_1, arg_2, or arg_3

• Explanation: The node encountered a data type in one of the optional arguments that it cannot process.
• Solution: Ensure that the data types passed to arg_1, arg_2, and arg_3 are compatible with the node's processing capabilities, typically simple data types like strings or numbers.
